Gov. Gavin Newsom’s office confirmed that on Saturday morning he tested positive for COVID-19 after exhibiting mild symptoms.
The positive test came the day after Newsom had met in San Francisco with New Zealand Prime Minister Jacinda Ardern to sign a new climate partnership agreement.
The Governor’s Office said he will continue to work remotely.
In accordance with local and state health guidelines, Newsom will remain in isolation at least through Thursday, June 2, and until he tests negative.
As outlined in California's SMARTER Plan, which focuses on testing and treatment, the governor will test prior to leaving isolation.
He also has received a prescription for Paxlovid, the antiviral that has been proven effective against COVID-19, and will begin his five-day regimen immediately.
Gov. Newsom is vaccinated and has received two booster shots, including as recently as May 18.
The Governor’s Office said vaccinations and boosters remain the best way to protect yourself from COVID-19.
California was the first state in the nation to announce a comprehensive plan to deal with COVID-19 going forward, the SMARTER plan, that focuses on testing and treating patients to avoid serious disease.
By following the guidelines outlined in the SMARTER plan, individuals can help protect themselves and others, and public officials can prepare for surges in COVID-19 transmission, like the one currently occurring across the country, Newsom’s office reported.
KELSEYVILLE, Calif. — After qualifying at their Spring Regional Leadership Conference in late February, seven students from the Kelseyville High School Advanced Culinary Arts class joined about 700 other attendees at the 75th annual California Family, Careers and Community Leaders of America State Leadership Conference held April 23 to 26 in Riverside.
All KHS students received either gold, silver or bronze seals in recognition of their scores, and KHS senior Karina Sonato placed third in state for her charcuterie board.
The Family, Careers and Community Leaders of America State Leadership Conference, or FCCLA, is a career technical student organization for students in grades sixth through 12th who are enrolled in Family and Consumer Sciences education programs in California public schools and the KHS Culinary Arts class is associated with the organization.
This was the first year KHS competed, and teacher Tami Cramer said she was “thrilled with the results” and looking forward to her students participating again next year.
This year’s participants included Karina Sonata, Sarahi Sonato and Estefani Ramirez Reyes, who) competed in culinary display: appetizers; as well as Delayna Dothage, Emily Jimenez, Briseyda Cacho and Anthony Ruiz Matias, who competed in salad preparation.
The theme of the conference, “Make it Count,” was intended to inspire members to get out of their comfort zone and get involved in all the activities and events.
In addition to competing, students attended statewide and regional meetings, workshops, industry visits, a formal banquet and a dance.
Approximately 70 FCCLA chapters from across the state competed for more than $1.6 million dollars in cash and scholarships in leadership and career development competition events.
This year, the following colleges provided FCCLA scholarships: Auguste Escoffier School of Culinary Arts, Culinary Institute of America, FIDM, Johnson and Wales University, and Sullivan University.
Instructional programs, career education, and competitive events relate to one or more of nine industry sector pathways that are included in FCS education programs, including: child development; education; consumer services; family and human services; fashion design and merchandising; interior design; food science, dietetics, and nutrition; hospitality, tourism and recreation; and food service and hospitality.

Organizers invite the community to join them for this important event to honor our veterans.
Imagine inhaling just a few drops of liquid or mist to get protected from COVID-19. That is the idea behind nasal COVID-19 vaccines, and they have been getting a lot of attention recently as a spray or liquid. These nasal vaccines would be based on the same technology as normal vaccines given by injection. But as Mayuresh Abhyankar, a University of Virginia researcher who studies infectious diseases and works on nasal vaccines, explains, vaccinating someone right where the coronavirus is likely to start its attack comes with many immunological benefits.
1. What are nasal vaccines?
Nasal vaccines are administered, as the name suggests, through the nose. More accurately called intranasal vaccines, these vaccines are liquids that can be given as a spray or through a dropper or syringe. The most common nasal vaccine is FluMist, a nasal spray that uses inactivated flu virus to protect against influenza. An intranasal vaccine could be a weakened live virus similar to FluMist, a nucleic acid vaccine like mRNA coronavirus vaccines or a protein vaccine like Hepatitis B vaccines or the CorbeVax coronavirus vaccine.
Intranasal vaccines are best suited to protect against pathogens that enter through the nose, like the flu or the coronavirus. By mimicking the first step of natural exposure to an airborne pathogen, these vaccines help train a person’s immune system at the potential place of infection. Scientists have shown that the first immune response in the respiratory tract after a person is exposed to an airborne virus can influence how sick a person gets. So in theory, intranasal vaccines could provide better protection than vaccines given through a shot in the arm.
2. How does the coronavirus infect people?
SARS-CoV-2, the virus that causes COVID-19, usually enters the body through the nose and lands on the mucus membrane at the back of the nasal passage and in the throat. The virus then enters the cells it touches, replicates and spreads.
Just underneath these cells of the mucus membrane are many types of immune cells that form what is called the mucosal immune system. Cells of the mucosal immune system are the first to identify invading coronavirus particles and start mounting a protective response.
Nasal vaccines follow a lot of the same steps. When you inhale a nasal vaccine, the particles land on the mucus membrane in your nasal cavity or the back of your throat, enter the cells in those places and trigger an immune response. This process teaches the body about the coronavirus and allows it to deal with any future real infections.
3. How are nasal and intramuscular vaccines different?
When you get a COVID-19 shot in your arm, the vaccine triggers a strong immune response in the cells near where you got the shot. It also causes your immune system to produce some coronavirus-specific antibodies and other immune cells in other locations throughout your body.
When the coronavirus begins infecting cells in a person’s respiratory tract, the immune cells nearby will start mounting a defense. Your body will also send anti-viral immune cells and antibodies from other locations to the site of infection. But by the time enough coronavirus-specific immune cells gather around the infection site to stop the virus from replicating, the virus has likely already begun to spread throughout the body, making it difficult for the immune system to keep up.
Nasal vaccines mimic the virus in order to prepare the immune system against a virus, just like any other vaccine. But importantly, they mimic the process of infection, too, and boost protective response within the mucosal immune system of the nose and throat. In simple terms, intranasal vaccines are like knowing there is going to be a break-in and putting your guards in the right location before the trouble even starts.
Nasal vaccination could also be used in concert with intramuscular immunization. In a recent study, my colleagues and I gave some mice both a nasal and intramuscular vaccine and exposed them to a lethal dose of SARS-CoV-2 – 100% of these mixed-vaccinated mice survived, compared to only 10% of the unvaccinated mice. We are now testing if this mixed approach is superior to just intranasal or just intramuscular approaches on their own.
Finally, intranasal vaccines are painless, noninvasive and do not require specialized training to use.
4. What are the risks of nasal vaccines?
Getting the dosage correct can be harder with nasal vaccines than a shot, especially with young children. If someone has a stuffy nose or sneezes out a part of the vaccine before it’s completely absorbed, this can result in a lower-than-desired dose.
There are some unique health risks too. All vaccines go through rigorous safety testing and clinical trials, but these processes are especially important for nasal vaccines due to the simple fact that the nose is close to the brain. In 2000, 27.7% of people who received an inactivated intranasal influenza vaccine in Switzerland developed transient facial paralysis – also known as Bell’s palsy. Later, researchers found that a bacterial toxin added to the vaccine to enhance the immune response was the culprit.
This is the only reported instance of neurological issues stemming from intranasal vaccines, but it is something to consider.
5. How long until intranasal COVID-19 vaccines are ready?
As of late May 2022, there are no approved COVID-19 intranasal vaccines for human use. There are currently seven in clinical trials, and three of them – manufactured by Beijing Wantai Biological Pharmacy, Bharat Biotech, and Codagenix and Serum Institute of India – are in phase-3 human trials.
In the coming months, the results of these trials will not only show how safe these promising new vaccines are, but also if they perform better than the vaccines in use today.
As Californians gear up for another beautiful summer full of outdoor recreation, boaters are being asked to remember the importance of cleaning, draining and drying their watercraft to combat the spread of invasive quagga and zebra mussels.
Quagga and zebra mussels are invasive freshwater mussels native to Europe and Asia. They multiply quickly, alter water quality and the aquatic food web, and ultimately impact native and sport fish communities. These mussels spread from one waterbody to another by attaching to watercraft, equipment and nearly anything that has been in an infested waterbody.
Invisible to the naked eye, microscopic juveniles are spread from infested waterbodies by water that is entrapped in boat engines, ballasts, bilges, live-wells and buckets.
Quagga mussels have infested 34 waters in Southern California and zebra mussels have infested two waters in San Benito County, 13 of which are boatable by the public.
To prevent the spread of these mussels and other aquatic invasive species, people launching vessels at any waterbody are subject to watercraft inspections and should clean, drain and dry their motorized and non-motorized boats, including personal watercraft and any equipment that contacts the water, before and after use.
“The California Department of Food and Agriculture (CDFA) operates border protection stations that inspect trailered watercraft entering the state,” said California Department of Fish and Wildlife Invasive Species Program Manager Martha Volkoff. “Early this year, the stations marked their two-millionth watercraft inspected, a milestone that represents a monumental contribution in preventing further introductions of mussels into the state. In addition to the border protection stations, water managers throughout the state continue to implement inspections at their waterbodies. Memorial Day is a great opportunity to spread the word to boaters about the simple actions they should take in preparation for their next outing.”
“Boaters need to conduct the ‘Clean, Drain and Dry’ practice each time they enjoy recreating on waterbodies,” said California State Parks Division of Boating and Waterways Acting Deputy Director Ramona Fernandez. “This responsible boating practice will help keep our water bodies free from invasive species, such as freshwater quagga and zebra mussels.”
Quagga and zebra mussels can attach to and damage virtually any submerged surface. They can:
• Ruin a boat engine by blocking the cooling system and causing it to overheat; • Jam a boat’s steering equipment, putting occupants and others at risk; • Require frequent scraping and repainting of boat hulls; • Colonize all underwater substrates such as boat ramps, docks, lines and other underwater surfaces, causing them to require constant cleaning; • Impose large expenses to owners.
CDFW advises boaters to take the following steps before leaving a waterbody to prevent spreading invasive mussels, improve the efficiency of their inspection experience and safeguard California waterways:
• CLEAN — inspect exposed surfaces and remove all plants and organisms, • DRAIN — all water, including water contained in lower outboard units, live-wells and bait buckets, and • DRY — allow the watercraft to thoroughly dry between launches. Watercraft should be kept dry for at least five days in warm weather and up to 30 days in cool weather.
Please visit websites for CDFW and California State Parks for extensive information on invasive species, the harm they can produce, and how California boaters can provide crucial assistance in the fight against invasive mussels.
Travelers are also advised to be prepared for inspections at CDFA border protection stations. Inspections, which can also be conducted by CDFW and California State Parks, include a check of boats and personal watercraft, as well as trailers and all onboard items.
Contaminated vessels and equipment are subject to decontamination, rejection, quarantine or impoundment.
CDFW, CDFA, State Parks and the California Department of Water Resources thank boaters for their continued and valuable cooperation in joining the fight against invasive quagga and zebra mussels.
LAKE COUNTY, Calif. — Caltrans held its Litter Cleanup Day on Thursday with crews and volunteers removing trash and debris along highways throughout the state.
In Del Norte, Humboldt, Lake, and Mendocino counties, Thursday’s event included District 1 crews removing litter from area highways and a call out to our communities to join in by picking up litter in their neighborhoods and nearby parks.
Litter Cleanup Day is part of Gov. Gavin Newsom’s Clean California initiative, a sweeping $1.1 billion, multiyear effort led by Caltrans to keep roads and waterways free of litter, create thousands of jobs, and transform state and local public spaces through beautification efforts.
“Litter on our roadways pollutes waterways, threatens wildlife and increases the risk of fire,” said Caltrans Acting Director Steven Keck. “Californians can be part of the solution by disposing of garbage responsibly, securing cargo properly and volunteering to collect litter through the Adopt-A-Highway program.”
Motorists can help prevent highway litter by following a few basic travel behaviors:
• Keep a trash bag in your vehicle and always dispose of garbage appropriately. • Properly extinguish cigarettes and cigars, and never throw any item, particularly one that is lit, from a vehicle. • Always cover and properly secure cargo or materials hauled in truck beds to prevent items from falling off the vehicle. • Volunteer to adopt a California highway and remove litter.
In January, Caltrans announced a Clean California incentive program that offers up to $250 per month to Adopt-A-Highway volunteers who pick up litter along state highways.
Since its inception in 1989, more than 120,000 Californians have cleaned more than 15,000 shoulder-miles of roadside.
The incentives augment the overall goals of the Clean California program to maintain and beautify the state's roadways.
Since launching Clean California in July, Caltrans has removed more than 630,000 cubic yards of litter from state highways — the equivalent of 10,600 tons or enough to fill 193 Olympic-size swimming pools — and hired 700 new team members as part of Clean California, including 482 maintenance workers who collect litter and remove graffiti.

Expanding California’s global climate leadership, Gov. Gavin Newsom on Friday established a new international climate partnership with New Zealand Prime Minister Jacinda Ardern.
California and New Zealand signed a memorandum of cooperation, or MOC, to tackle the climate crisis, reduce pollution, and bolster the clean economy, while emphasizing community resilience and partnership with indigenous leaders.
In the New Zealand Garden at the San Francisco Botanical Garden in Golden Gate Park, California and New Zealand outlined common objectives to achieve carbon-neutrality by mid-century, as well as their shared world-leading policies for zero-emission transportation, climate innovation, clean power generation, nature-based solutions, and zero waste initiatives.
The MOC furthers these common objectives through sharing information and best practices. A copy of the MOC signed today can be read below.
“Later is too late to address climate change, and California is taking aggressive steps to bolster the clean economy while reducing pollution in our communities – but we can’t do it alone,” said Gov. Newsom. “This partnership with New Zealand, another global climate leader, will strengthen ties between our two governments to deploy critical solutions that are essential to addressing this existential crisis.”
“No country is immune from the impacts of climate changes, so it’s just common sense to collaborate with like-minded partners to meet our mutual goals,” said Prime Minister Jacinda Ardern. “We both aim to achieve net zero carbon emissions by the middle of the century. This agreement means we’ll work together to share expertise and experience and collaborate on projects that help meet each other’s targets.”
California’s world-leading climate policies have led the state to exceed its 2020 climate target four years ahead of schedule, and created partnerships across the U.S. and around the world.
Gov. Newsom has committed $47.1 billion to tackle pollution, build climate-resilient water supplies, reduce the risk of catastrophic wildfires, ensure grid reliability and accelerate clean energy solutions, and protect communities from extreme heat.
California’s ZEV market is leading the nation in every category and the state is ending the sale of new gas cars by 2035, reducing demand for oil and spurring partnerships across the nation and around the world.
Responding to the governor’s nature-based solutions executive order, which identified California’s lands as a critical yet underutilized sector in the fight against climate change, California last month released the Pathways to 30x30: Accelerating Conservation of California’s Nature strategy and Natural and Working Lands Climate Smart Strategy.
Earlier this year, California signed a Memorandum of Cooperation with Japan to advance cooperation on climate and clean energy priorities, and strengthen trade relations.
Gov. Newsom also signed a Memorandum of Understanding with China to accelerate ongoing initiatives to protect the environment, reduce carbon and air pollution, and promote clean technology development.
Last year, Gov. Newsom and 24 governors from the bipartisan U.S. Climate Alliance committed to collectively achieve net-zero greenhouse gas emissions no later than 2050.
Gov. Newsom and other Under2 Coalition partners announced the transition to become a net zero coalition, raising ambition for member states and regions.
California also joined the Beyond Oil & Gas Alliance, which brings together national and subnational governments committed to advancing a just transition away from oil and gas production.
In the wake of the recent, horrific shootings in Buffalo, New York, and Uvalde, Texas, and the nation’s long history of devastating firearm-related massacres, Assemblymember Cecilia Aguiar-Curry (D-Winters) announced on Thursday her support for a package of legislation adopted by the State Assembly to stem the scourge of mass shootings.
“We are the only country in the world where the regulation of guns and gun-ownership is treated with such callous disregard, where no place is safe, including places of worship, grocery stores and elementary schools,” said Aguiar-Curry, whose Fourth Assembly District includes Lake County.
“I want to make very clear that these bills do nothing to infringe upon the rights of law-abiding gun owners,” she said. “They are meant to increase attention to violence prevention, increase transparency, and promote registration of and accountability for gun manufacturers. These measures will help. But, until the US Congress takes up such common sense measures as Congressman Mike Thompson’s HR 8, The Bipartisan Background Checks Act of 2021 and renews the ban on assault weapons and other implements of war, Californians will be at continued risk.
The bill package includes:
• AB 2571 (Bauer-Kahan) Prohibits firearm industry members from marketing or advertising firearm-related products to minors and authorizes public attorneys and injured plaintiffs to bring a civil action to enforce the prohibition, obtain injunctive relief, and seek either civil penalties, or, in some cases, damages for harms caused by a violation.
• AB 1621 (Gipson) Changes the definition of a firearm and firearm precursor part and prohibits a person from possessing or manufacturing a firearm precursor part without authorization, seeking to address the rising problem of ghost guns..
• AB 2156 (Wicks) Reduces, from 50 to three, the number of firearms a person, firm or corporation may manufacture in a calendar year without having a state license to manufacture firearms. Also prohibits a person, firm or corporation from using a 3D printer to manufacture any firearm, including a frame or receiver, or any firearm precursor part, without having a state license to manufacture firearms.
• AB 2552 (McCarthy) Mandates additional notices related to the storage, handling, purchase and theft of a firearm be posted at each public entrance of any gun show, event or exposition and requires the California Dept. of Justice to inspect half of all gun shows and events every year.
• AB 1929 (Gabriel) Requires the Department of Health Care Services (DHCS) to establish a community violence prevention and recovery program, under which violence-preventive services are required to be provided by qualified violence prevention professionals as a covered benefit under the Medi-Cal program. Defines the eligibility of Medi-Cal beneficiaries for violence prevention services, and training and certification program and continuing education requirements for violence preventive professionals.
• AB 2239 (Maeinschein) Creates a 10-year firearm prohibition for individuals convicted of child abuse and elder and dependent adult abuse involving violence.
“Before I am an Assemblywoman, I am a mother and grandmother,” Aguiar-Curry said. “Too many mothers and grandmothers have buried their loved ones in the wake of violence like what we saw yesterday in Texas. I was proud to support these measures, which are supported by the vast majority of Americans and a majority of gun owners.”
More Americans died of gun-related injuries in 2020 than in any other year on record, according to recently published statistics from the Centers for Disease Control and Prevention.
That included a record number of gun murders, as well as a near-record number of gun suicides.
Nearly eight in 10 (79%) U.S. murders in 2020 — 19,384 out of 24,576 — involved a firearm. That marked the highest percentage since at least 1968, the earliest year for which the CDC has online records.
“Too many Californians have faced what families in Uvalde faced last night — empty beds and broken hearts,” Assemblymember Aguiar-Curry said. “These bills will take real steps toward keeping guns out of the hands of those who would do harm.”
With its mirror segments beautifully aligned and its scientific instruments undergoing calibration, NASA’s James Webb Space Telescope is just weeks away from full operation. Soon after the first observations are revealed this summer, Webb’s in-depth science will begin.
Among the investigations planned for the first year are studies of two hot exoplanets classified as “super-Earths” for their size and rocky composition: the lava-covered 55 Cancri e and the airless LHS 3844 b.
Researchers will train Webb’s high-precision spectrographs on these planets with a view to understanding the geologic diversity of planets across the galaxy, and the evolution of rocky planets like Earth.
Super-hot super-Earth 55 Cancri e
55 Cancri e orbits less than 1.5 million miles from its Sun-like star (1/25th of the distance between Mercury and the Sun), completing one circuit in less than 18 hours. With surface temperatures far above the melting point of typical rock-forming minerals, the day side of the planet is thought to be covered in oceans of lava.
Planets that orbit this close to their star are assumed to be tidally locked, with one side facing the star at all times. As a result, the hottest spot on the planet should be the one that faces the star most directly, and the amount of heat coming from the day side should not change much over time.
But this doesn’t seem to be the case. Observations of 55 Cancri e from NASA’s Spitzer Space Telescope suggest that the hottest region is offset from the part that faces the star most directly, while the total amount of heat detected from the day side does vary.
Does 55 Cancri e have a thick atmosphere?
One explanation for these observations is that the planet has a dynamic atmosphere that moves heat around.
“55 Cancri e could have a thick atmosphere dominated by oxygen or nitrogen,” explained Renyu Hu of NASA’s Jet Propulsion Laboratory in Southern California, who leads a team that will use Webb’s Near-Infrared Camera, or NIRCam, and Mid-Infrared Instrument, or MIRI, to capture the thermal emission spectrum of the day side of the planet.
“If it has an atmosphere, [Webb] has the sensitivity and wavelength range to detect it and determine what it is made of,” Hu added.
Or is it raining lava in the evening on 55 Cancri e?
Another intriguing possibility, however, is that 55 Cancri e is not tidally locked. Instead, it may be like Mercury, rotating three times for every two orbits (what’s known as a 3:2 resonance). As a result, the planet would have a day-night cycle.
“That could explain why the hottest part of the planet is shifted,” explained Alexis Brandeker, a researcher from Stockholm University who leads another team studying the planet. “Just like on Earth, it would take time for the surface to heat up. The hottest time of the day would be in the afternoon, not right at noon.”
Brandeker’s team plans to test this hypothesis using NIRCam to measure the heat emitted from the lit side of 55 Cancri e during four different orbits. If the planet has a 3:2 resonance, they will observe each hemisphere twice and should be able to detect any difference between the hemispheres.
In this scenario, the surface would heat up, melt, and even vaporize during the day, forming a very thin atmosphere that Webb could detect. In the evening, the vapor would cool and condense to form droplets of lava that would rain back to the surface, turning solid again as night falls.
Somewhat cooler super-Earth LHS 3844 b
While 55 Cancri e will provide insight into the exotic geology of a world covered in lava, LHS 3844 b affords a unique opportunity to analyze the solid rock on an exoplanet surface.
Like 55 Cancri e, LHS 3844 b orbits extremely close to its star, completing one revolution in 11 hours. However, because its star is relatively small and cool, the planet is not hot enough for the surface to be molten. Additionally, Spitzer observations indicate that the planet is very unlikely to have a substantial atmosphere.
What is the surface of LHS 3844 b made of?
While we won’t be able to image the surface of LHS 3844 b directly with Webb, the lack of an obscuring atmosphere makes it possible to study the surface with spectroscopy.
“It turns out that different types of rock have different spectra,” explained Laura Kreidberg at the Max Planck Institute for Astronomy. “You can see with your eyes that granite is lighter in color than basalt. There are similar differences in the infrared light that rocks give off.”
Kreidberg’s team will use MIRI to capture the thermal emission spectrum of the day side of LHS 3844 b, and then compare it to spectra of known rocks, like basalt and granite, to determine its composition. If the planet is volcanically active, the spectrum could also reveal the presence of trace amounts of volcanic gases.
The importance of these observations goes far beyond just two of the more than 5,000 confirmed exoplanets in the galaxy. “They will give us fantastic new perspectives on Earth-like planets in general, helping us learn what the early Earth might have been like when it was hot like these planets are today,” said Kreidberg.
These observations of 55 Cancri e and LHS 3844 b will be conducted as part of Webb’s Cycle 1 General Observers program. General Observers programs were competitively selected using a dual-anonymous review system, the same system used to allocate time on Hubble.
The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it.
Webb is an international program led by NASA with its partners, European Space Agency and the Canadian Space Agency.

Video from the navigation camera aboard NASA’s Ingenuity Mars Helicopter shows its record-breaking 25th flight on April 8, 2022. Covering 2,310 feet (704 meters) at a maximum speed of 12 mph (5.5 meters per second), it was the rotorcraft’s longest and fastest flight to date. Credits: NASA/JPL-Caltech.
Imagery has come down from Mars capturing a recent flight in which the rotorcraft flew farther and faster than ever before.
The Ingenuity Mars Helicopter’s black-and-white navigation camera has provided dramatic video of its record-breaking 25th flight, which took place on April 8.
Covering a distance of 2,310 feet at a speed of 12 miles per hour, it was the Red Planet rotorcraft’s longest and fastest flight to date. (Ingenuity is currently preparing for its 29th flight.)
“For our record-breaking flight, Ingenuity’s downward-looking navigation camera provided us with a breathtaking sense of what it would feel like gliding 33 feet above the surface of Mars at 12 miles per hour,” said Ingenuity team lead Teddy Tzanetos of NASA’s Jet Propulsion Laboratory in Southern California.
The first frame of the video clip begins about one second into the flight. After reaching an altitude of 33 feet, the helicopter heads southwest, accelerating to its maximum speed in less than three seconds.
The rotorcraft first flies over a group of sand ripples then, about halfway through the video, several rock fields. Finally, relatively flat and featureless terrain appears below, providing a good landing spot. The video of the 161.3-second flight was speeded up approximately five times, reducing it to less than 35 seconds.
The navigation camera has been programmed to deactivate whenever the rotorcraft is within 3 feet of the surface. This helps ensure any dust kicked up during takeoff and landing won’t interfere with the navigation system as it tracks features on the ground.
Ingenuity’s flights are autonomous. “Pilots” at JPL plan them and send commands to the Perseverance Mars rover, which then relays those commands to the helicopter.
During a flight, onboard sensors — the navigation camera, an inertial measurement unit, and a laser range finder — provide real-time data to Ingenuity’s navigation processor and main flight computer, which guide the helicopter in flight. This enables Ingenuity to react to the landscape while carrying out its commands.
Mission controllers recently lost communication with Ingenuity after the helicopter entered a low-power state. Now that the rotorcraft is back in contact and getting adequate energy from its solar array to charge its six lithium-ion batteries, the team is looking forward to its next flight on Mars.
The Ingenuity Mars Helicopter was built by JPL, which also manages the project for NASA Headquarters. It is supported by NASA’s Science Mission Directorate. NASA’s Ames Research Center in California’s Silicon Valley and NASA’s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity’s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Space designed and manufactured the Mars Helicopter Delivery System.
At NASA Headquarters, Dave Lavery is the program executive for the Ingenuity Mars Helicopter.
The Employment Development Department on Thursday announced it has blocked a recent unemployment insurance fraud attempt involving crooks trying to steal hundreds of millions in benefits using paper and fax applications.
EDD is now mailing notices to claimants to separate the fraud attempts from any legitimate claims.
This latest scheme involved fraudsters flooding EDD with unemployment insurance claims filed by paper and fax — including as many as 47,000 potentially fraudulent claims earlier this month. EDD would normally expect to receive roughly 7,000 such applications in that time frame.
EDD did not pay the potentially fraudulent claims and its action prevented up to $560 million in potential unemployment insurance fraud.
“EDD’s tough new fraud filters thwart a constant stream of new fraud attempts, schemes and criminal tactics” said EDD Fraud Special Counsel McGregor Scott. “These criminals again tried to pierce the Department’s defenses but we stopped them dead in their tracks.”
The work of fraudsters in this case will likely slow claims for some paper-filing claimants as EDD separates the fraud attempts from legitimate claims.
EDD is mailing notices to all paper and fax benefit applicants to quickly identify any legitimate claimant and disqualify all fraudulent ones.
The mailed notices explain that an issue must be resolved before any benefits are paid, and include information about fraud reporting.
Any legitimate claimant who receives an EDD notice should respond with the requested verification right away and EDD will review and process the legitimate claim.
Some Californians may receive multiple notices from EDD if a scammer tried to file multiple claims in their name. EDD’s mailed notices are part of its fraud fighting system and help warn potential identity theft victims that fraudsters are attempting to use their personal information.
Californians who suspect fraudulent activity, including those receiving mailed EDD notices and did not apply for benefits, should report the fraud as indicated on the mailed notice and call 1-866-401-2849 for assistance. Californians can also report benefits fraud by visiting Report Fraud in Ask EDD. EDD has additional resources to help identity theft victims on the Help Fight Fraud webpage.
EDD encourages Californians to stay vigilant against scam attacks. Scammers attempt to get personal information in many sophisticated and creative ways.
Scammers may “phish” for victims by pretending to be banks, stores, or even government agencies. They do this over the phone, in emails, by text message, in the regular mail, and by other communications forms. Once scammers have stolen this information they may attempt to file false benefit claims.
EDD runs one of the nation’s largest public benefit systems. Over 20 million people filed over 60 million unemployment, disability insurance, and paid family leave claims over the past decade. EDD prepared, printed and mailed 45 million documents to customers through the most recent fiscal quarters. EDD was mailing nearly 600,000 a day during the height of the pandemic.
In response to the unprecedented increase in fraudulent unemployment claims related to the COVID-19 pandemic, EDD implemented new safeguards in 2020 to detect and prevent identity theft and other organized criminal activities, including identity verification through ID.me and cross-checking applications against law enforcement databases from Thomson Reuters.
EDD’s new anti-fraud measures blocked an estimated $125 billion in unemployment fraud attempts during the pandemic. Still, fraudsters continue trying new tactics. Last year, EDD detected and halted a complex scheme involving stolen medical or health provider credentials.
Fraudsters flooded EDD with over 30,000 fake medical provider accounts, forcing EDD to review hundreds of thousands of claims associated with those accounts and block billions of dollars in fraud attempts.
As part of its effort to better serve Californians, EDD invested in cutting-edge document production and distribution systems to deliver millions of documents to Californians and keep them informed about the status of claims during the pandemic.
“Criminals will probe for weakness every day of the year and EDD will keep blocking them,” said Scott. “EDD will continue to strengthen its fraud fighting capability and remind Californians to guard against identity theft.”
