Avio to begin testing its own Grasshopper prototype later this year

10:01 am

According to recent changes to its proposed plans, it appears that the Italian rocket company Avio hopes to begin tests of its own Grasshopper prototype vertical takeoff-and-landing stage later this year, with the hope of incorporating a reusable first stage in its upgraded Vega-Next rocket.

In the latest rendering shared in Avio’s 2024 full-year financial results presentation, control surfaces resembling those on a Falcon 9 booster are visible, seemingly confirming that the stage will be used to explore reusability.

In addition to the new rendering, Avio’s 2024 full-year financial results presentation included an update on the progress of the IFD1 mission. According to the company, integration of the demonstrator is ongoing, with an initial “firing test” expected in the third quarter of 2025. This test will likely be the final major milestone before the demonstrator is launched.

The company is targeting a 2032 first orbital launch of Vega-Next. Right now Avio owns the Vega-C rocket, and is the only private rocket company in Europe launching its own rocket. The only other operational European rocket, the larger Ariane-6, is operated by the European Space Agency. Another half-dozen-plus new private rockets are under development by other European rocket startups, but non have so far launched.

Norway awards the German rocket startup Isar Aerospace a two-satellite contract

9:48 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

In what appears to be a concerted effort by Norway to cement the establishment of its Andoya spaceport on its northwest coast, last week it awarded a two-satellite launch contract to the German rocket startup Isar Aerospace, launching from that spaceport.

The launch is scheduled until 2028 and will take place from Andøya Spaceport, Europe’s first operational spaceport on the mainland. The agreement between the Norwegian Space Agency and Isar Aerospace involves launching two Norwegian satellites as part of the AOS program, a national maritime surveillance system.

Isar is now gearing up for the very first orbital test launch of its Spectrum rocket, which will also be the very first from Andoya, and the very first from the four proposed spaceports in Europe. Regulatory filings from Norway suggest it will occur during a ten-day launch window beginning on March 20, 2025, but Isar has not yet confirmed this.

Unlike the two UK spaceports, which have been delayed years due to government red tape, Norway’s government has apparently worked hard to cut red tape and help Isar get off the ground quickly. It also appears that Norway’s government is acting to stymie Sweden’s Esrange spaceport, releasing a report last week that suggested it will not give permission for launches over its territory from Esrange.

Varda’s third capsule begins orbital operations

9:37 am

Varda's space capsule, on the ground in Utah
Varda’s first capsule on the ground in Utah.

The in-space commercial company Varda on March 15, 2025 confirmed that its third capsule has successfully begun orbital operations after its launch on a Falcon 9 rocket, carrying an Air Force payload that will test measuring the capsule’s re-entry speeds in connection with military hypersonic research.

W-3’s payload is an advanced navigation system called an Inertial Measurement Unit (IMU) developed by the US Air Force and Innovative Scientific Solutions Incorporated (ISSI). This payload will be tested at reentry speeds it was designed to withstand but has never encountered before.

This payload is part of a $48 million Air Force contract awarded to Varda in December. The company also notes in the press release that it is aiming for a monthly launch rate for its capsules, which provide customers an opportunity to do all kinds of in-space testing and manufacturing. Since this launch took place only fifteen days after the landing of its second capsule, it appears Varda is moving swiftly in that direction, thus providing more business for American rocket startups.

The capsule includes a service module built by Rocket Lab, and will stay in orbit several weeks before it returns to Earth, landing at the Koonibba Test Range in South Australia, operated by the Australian commercial spaceport startup Southern Launch.

Firefly’s Blue Ghost ends its mission, having achieved all its mission goals

9:23 am

after landing, with the Earth in the background.

Five hours after lunar sunset Firefly yesterday shut down its Blue Ghost lander, ending its mission after successfully completing all its assigned tasks in carrying ten NASA research payloads to the Moon and softly placing them on the lunar surface.

Firefly also captured imagery of the lunar sunset on March 16, providing NASA with data on whether lunar dust levitates due to solar influences and creates a lunar horizon glow that was hypothesized and observed by Eugene Cernan on Apollo 17. Following the sunset, Blue Ghost operated for 5 hours into the lunar night and continued to capture imagery that measures how dust behavior changes after sunset.

“Whether lunar dust levitates” is one of the biggest scientific mysteries about the Moon. Only one person, astronaut Harrison Schmidt, has observed the phenomenon during the last Apollo mission to the Moon, and numerous attempts since to confirm and better understand it have all failed for one reason or the other. The preliminary results of Blue Ghost observations will be announced at a press conference tomorrow.

Firefly is now gearing up for annual Blue Ghost lunar missions. The next is targeting a launch next year, and will also deliver payloads for NASA, the European Space Agency, and Australia.

Chinese pseudo-company launches 8 satellites

9:09 am

The Chinese pseudo-company Galactic Energy today successfully placed eight remote-sensing satellites into orbit, its solid-fueled Ceres-1 rocket lifting off from the Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages crashed inside China.

This was Ceres-1’s eighteenth launch, making Galactic Energy the most successful rocket pseudo-company so far in China. That its rocket uses solid-fueled shows us however that it is strongly tied to China’s military, and likely controlled tightly by it.

Norway questions Sweden’s plan to launch orbital rockets from Esrange spaceport

12:56 pm

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

In the capitalist competition between Norway, Sweden, and the United Kingdom to establish Europe’s prime launch site, Norway’s government has now issued a long study questioning Sweden’s plan to launch orbital rockets from its Esrange spaceport, since polar launches heading north from there will have to cross Norway.

You can read the report here [pdf]. For Esrange to conduct orbital launches it will need the permission of Norway for each launch, and it appears Norway is not satisfied with Sweden’s assessments that say launches can occur safely. The report concludes:

Norway recommends that the relevant Norwegian authorities conduct an assessment of the risks a launch will pose to the people in Norway and Norwegian interests, and determine whether this risk is acceptable, taking into account the interests and safety of the Norwegian people and the severity of the risk.

…Due to the significant economic costs associated with the impact on oil and gas production in
the Barents Sea, CAA Norway recommends that no launches be permitted in areas where there
is any risk to Norwegian oil and gas installations.

The release of this report illustrates Norway’s geographic advantages. The German rocket startup Isar is gearing up to do its first launch from Norway’s new spaceport, Andoya, possibly before the end of this month. It will have a clear path to space. Meanwhile, the American rocket startup Firefly, which wants to launch from Esrange, faces serious regulatory hurdles from neighboring countries, like Norway, because any rocket must fly over their territories.

Four more launches, two by SpaceX, following manned launch

10:33 am

Following SpaceX’s successfully launch of four astronauts to ISS yesterday afternoon, the launch industry upped the pace by completing four more launches in the next few hours, two by SpaceX, one by Rocket Lab, and one by China.

Beginning with SpaceX, it first launched another one of its Transporter missions, carrying about three dozen smallsat payloads, its Falcon 9 rocket lifting off from Vandenberg. The first stage completed its thirteenth flight, landing on a drone ship in the Pacific. The two fairings completed their eighth and eleventh flights respectively.

Five hours later the company launched another 23 Starlink satellites, the Falcon 9 lifting off from Cape Canaveral in Florida, with the first stage completing its eighteenth flight, landing on a drone ship in the Atlantic.

Rocket Lab meanwhile successfully placed the first of eight commercial radar satellites into orbit for the Japanese satellite company iQPS, its Electron rocket launching from one of its two launchpads in New Zealand.

China in turn used its Long March 2D rocket to place two satellites into orbit, lifting off from its Jiuquan spaceport in northwest China. Its state-run press provided little information about either satellite. Nor did it provide any information about where the rocket’s lower stages — using very toxic hypergolic fuel — crashed inside China.

The leaders in the 2025 launch race:

SpaceX launches new crew to ISS

10:16 pm

Falcon 9 first stage barreling home to Florida
Falcon 9 first stage barreling home to Florida tonight.

After a scrub two days ago due to a ground equipment issue, SpaceX tonight successfully launched a new crew of four to ISS, its Falcon 9 rocket lifting off from Kennedy in Florida.

The Dragon capsule is Endurance, on its fourth flight. The first stage completed its third flight, landing back in Florida.

This launch will allow the two-person crews launched by Boeing’s Starliner capsule in June and SpaceX’s Freedom capsule in September to come back home on Freedom.

When it was decided not to allow the Starliner astronauts to come home on Starliner because of thruster issues on the capsule, NASA decided to keep its ISS launch schedule as normal as possible, thus forcing that crew to complete a mission of about eight months, with a planned return in February 2025. Initially their Starliner mission was expected to last anywhere from two weeks to two months-plus, depending on how well Starliner functioned while docked to ISS.

An evening pause: Actually Dovydas is a street performer who provides the background music and asks passersby if they want to sing something. Diane was listening to this across our house and I asked her if that was Stevie Nicks and Fleetwood Mac. Nope, but about as good. The singer’s name is Brielle Anderson, as per the first comment on the youtube page.

Florida’s two senators introduce bill to move NASA HQ to their state

2:25 pm

It what seems to be a direct response to the demand earlier this week by Ohio state and federal lawmakers to make Ohio the new home of NASA’s headquarters, Florida’s two senators today introduced a bill that would legally require the headquarters go to Florida instead.

The bill [pdf] itself is short, barely more than two paragraphs, and if passed would simply require the headquarters to move to Florida’s Brevard County within one year of enactment.

The last word however is critical. There is no chance this idiotic bill will be passed. The only reason these senators introduced it today is to up their game against Ohio and any other state that wants NASA’s headquarters moved there.

And if it is passed by some miracle? It will then become a perfect example of congressional micromanaging in the stupidest way.

Scientists issue new map of land below Antarctica’s icecap

1:18 pm

Map of Antarctica's estimated land mass
Click for original image.

Using decades of data and more advanced computer software, scientists have now compiled the most detailed map of the land and shorelines hidden below Antarctica’s massive icecap.

The map to the right, reduced to post here, shows that bedrock terrain generally in hues of green to brown, with lower elevations comparable to the ocean in hues of blue. The actual shoreline is however impossible to determine, since without the pressure of the icecap on top, the continent would rise, while the ocean itself would also rise with the addition of all that water.

You can read the science paper here.. From the press release:

Known as Bedmap3, it incorporates more than six decades of survey data acquired by planes, satellites, ships and even dog-drawn sleds. … The map gives us a clear view of the white continent as if its 27 million cubic km of ice have been removed, revealing the hidden locations of the tallest mountains and the deepest canyons.

One notable revision to the map is the place understood to have the thickest overlying ice. Earlier surveys put this in the Astrolabe Basin, in Adélie Land. However, data reinterpretation reveals it is in an unnamed canyon at 76.052°S, 118.378°E in Wilkes Land. The ice here is 4,757 m thick, or more than 15 times the height of the Shard, the UK’s tallest skyscraper.

The paper describes at length the large uncertainties that exist in this data. As thorough as they tried to be, we must remember that Antarctica is very large with a very hostile environment. Much of it has never been visited by any humans. Getting an accurate picture of the thickness of the ice at all points is presently impossible. This is basically an excellent summary of our best guess.

Europe’s Hera asteroid probe sends back data from Mars fly-by

1:00 pm

Deimos and Mars as seen by Hera
Click to see full movie.

The European Space Agency (ESA) Hera probe, on its way to study the Didymos/Dimorphos asteroid binary, has successfully sent back images and data obtained during its close-by of Mars yesterday.

The infrared image to the right, a screen capture from a short movie assembled from Hera’s first images, shows the Martian moon Deimos with Mars in the background. The mission scientists have compiled all of these first images taken by Hera to create a short movie, that I have embedded below. From the movie’s caption:

The car-sized Hera spacecraft was about 1000 km away from Deimos as these images were acquired. Deimos orbits approximately 23 500 km from the surface of Mars and is tidally locked, so that this side of the moon is rarely seen. Hera’s TIRI – supplied to the mission by the Japan Aerospace Exploration Agency, JAXA – sees in mid-infrared spectral bands to chart surface temperature. Because Deimos lacks an atmosphere, the side of the moon being illuminated by the Sun is considerably warmer than the planet beneath it.

Although it appears as if Deimos is passing in front of Mars from south to north, the image was actually taken as Hera passed very close to Deimos from north to south at high speed.

Deimos appears brighter than Mars. This means that the surface of airless Deimos is hotter than the surface of Mars. The material covering the surface of Deimos has low reflectivity and is pitch black. This allows it to absorb sunlight well and become hotter. In contrast, the surface of Mars is highly reflective, and its atmosphere transports heat from the warm daytime side to the cooler nighttime side. This is why there is a large temperature difference between Mars and Deimos.

These infrared images also tell us the excellent quality of the camera. Note how detailed the features are on the Martian surface. When Hera gets to Didymos/Dimorphos in December 2026 it is going to be able to document those two asteroids in remarkable detail, including the results of the Dart impact on Dimorphos in September 2022.

Ghana hires Axiom to help it develop its space industry

12:02 pm

Ghana and the American space station startup Axiom yesterday signed a deal whereby Axiom would provide Ghana’s Space Science and Technology Institute (GSSTI) advice and help in developing its own space projects.

The deal does not involve flying any astronauts into space, likely because Ghana simply can’t afford it. However, Axiom’s long experience working with NASA and flying astronauts to ISS gives it enough value that it can still make money providing advice and aid to poorer countries.

Whether Ghana will really benefit remains unclear. The government recently approved a national space policy, but that policy was mostly designed to establish a government bureaucracy, not encourage private enterprise. If this Axiom deal will provide educational aid than it might produce something. If instead the deal has Axiom working only with that bureaucracy don’t expect much.

Axiom however will welcome this extra cash. It illustrates another profit center for all American space companies.

Pick a perfect March Madness bracket and SpaceX will award you a trip to Mars

10:55 am

College basketball fans now have a second motivation for predicting perfectly the team results during the March NCAA championship finals: SpaceX will award a perfect bracket a trip to Mars.

In a post from X’s business account, the platform officially announced their bracket challenge, partnered with their sponsor Uber Eats, announcing that anyone with a perfect bracket would win a trip to Mars as a part of the SpaceX program.

Those who are at least 18 years old and submit their bracket on X between March 16, after the CBS Selection Show, and the first game of the Round of 64 on March 20 will be eligible for the prize.

For those who don’t wish to travel to Mars, anyone who fills out a perfect bracket in the challenge could alternatively accept a prize of $250,000 and additional perks involved with the SpaceX program. This includes 1 year of free residential Starlink service, the chance to train like a SpaceX astronaut for a day, an opportunity to send a personal item of choice to space on a Falcon 9 launch, VIP viewing of a Starship launch.

If no one picks a perfect bracket (which is normally the case) a $100,000 prize was be awarded to the best non-perfect bracket.

Launch window for first launch of German rocket startup Isar rocket revealed

10:39 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

According to filings from the Norway’s Andoya spaceport, the launch window for Germany’s rocket startup Isar Aerospace for the first test orbital launch of its Spectrum rocket is now from March 20, 2025 to March 30, 2025.

On 12 March, Andøya Space, the mostly government-owned commercial entity that operates Andøya Spaceport, published a launch period notice covering 20 to 30 March. In relation to a maritime danger-area warning, the notice specifies launch windows between 12:30 and 16:30 CET throughout the 11-day period.

While the notice does not explicitly mention Isar Aerospace, as the company is currently the launch site’s sole customer, it can only refer to Isar. The company itself has yet to make a formal announcement regarding the published launch window.

In general Isar has been very closed-mouthed about its launch plans, so this supposition is not uncertain. The article however is right that there is no other rocket entity at Andoya that the launch window could refer to.

If Isar succeeds at this launch, it will win the race among about a half dozen European rocket startups to get an orbital launch off the ground first. Rocket Factory Augsburg had hoped to launch last year, but a fire during the one of the last rocket engine tests destroyed the rocket.

Regardless of whether Isar’s launch is successful, Norway meanwhile will win the race to be the first European spaceport to achieve an orbital launch. Though it shifted to orbital commercial operations much later than the two UK spaceports, years of regulatory red tape has prevented those UK spaceports from launching.

Blue Ghost watches the Earth eclipse the Sun from the Moon

10:23 am

Eclipse as seen by Blue Ghost
Click for original image.

Firefly’s Blue Ghost lunar lander last night successfully recorded images and data as the Earth slowly over hours crossed the face of the Sun, producing an eclipse.

The image to the right, cropped and reduced slightly to post here, is one such image. From the Firefly update page:

Captured at our landing site in the Moon’s Mare Crisium around 3:30 am CDT, the photo shows the sun about to emerge from totality behind Earth. This marks the first time in history a commercial company was actively operating on the Moon and able to observe a total solar eclipse where the Earth blocks the sun and casts a shadow on the lunar surface. This phenomenon occurred simultaneously as the lunar eclipse we witnessed on Earth.

The company has the right to tout its success, since it is the first of five private companies to actually succeed at a landing on the Moon. However, this is not the first such eclipse captured by a lander on the Moon. Surveyor 3 did it in April 1967, while Japan’s Kaguya orbiter did it also in 2009. (Watch this great lecture outlining the entire Surveyor program, presented during the 50th anniversary of its success. Hat tip reader Richard M.)

It is now past noon on the Moon, the temperatures will begin dropping, and Firefly will begin reactivating some instruments for the final week of operations before lunar sunset and shutdown for the long very cold lunar night.

Is the nomination of Jared Isaacman as NASA’s administrator facing political headwinds?

10:18 am

Jared Isaacman
Jared Isaacman

I admit immediately that I have no inside information to back up the speculation that will follow. Instead, it is based entirely on my fifty years of experience observing the political machinations that take place inside the DC swamp.

In the past week there have been a slew of stories all aimed at pressuring Congress to quickly confirm Jared Isaacman (billionaire, jet pilot, businessman, and commercial astronaut), Trump’s pick to be NASA’s next administrator. For example, two days ago NASA’s last Republican-appointed administrator Jim Bridenstine publicly called for Isaacman’s confirmation by the Senate.

“I think Jared Isaacman is going to be an amazing NASA administrator,” he said. “I think he’s got all the tools to be what could be the most consequential NASA administrator given the era in which we live in now.” That era, he said, involves greater reliance on commercial space capabilities. “He’s going to be able to take that and do things that have never been able to be done before.”

This week there was also an article in Space News, touting Isaacman’s desire to increase funding to NASA’s planetary defense program, expressed by him in February when it looked like asteroid 2024 YR4 had a good chance of hitting the Earth in 2032.

Furthermore, a group of seven Republican senators this week also joined the chorus, sending a letter [pdf] to Senators Ted Cruz (R-Texas) and Maria Cantwell (D-Washington), the chair and ranking members respectively of the Senate Commerce, Science, and Transportation Committee, extolling Isaacman in glowing terms and calling for his quick confirmation.

So with all this enthusiastic support bubbling out everywhere, why do I suspect Isaacman might actually be in trouble?

Indian engineers successfully undock its two Spadex robot satellites

9:33 am

After a delay of several months following the first autonomous robotic docking of its two-satellite Spadex mission, engineers from India’s space agency ISRO have now successfully undocked the chase satellite from its target satellite.

According to ISRO, the in-orbit performance of the docked satellites was extensively analysed, with a viable operational window identified from March 10 to March 25. Isro plans to conduct further experiments with the satellites in the coming days.

…Now that the undocking is complete, more docking attempts are expected to evaluate: How precisely ISRO can execute multiple docking maneuvers, how well the algorithms perform under various conditions, how the integrated inertial systems function and how the propulsion system performs during repeated operations.

These rendezvous and docking capabilities are essential for India to achieve its goal of building a manned space station and resupplying it on a regular basis.

Ohio lawmakers lobby Trump to move NASA headquarters there

9:26 am

In a letter [pdf] dated March 11, 2025 to both vice president J.D. Vance and Jared Isaacman, presently nominated to become NASA administrator, a group of federal and state lawmakers from Ohio urged the Trump administration to move the agency’s headquarters to their state.

“While we recognize that other states, including Florida, Alabama, and Texas, may pursue similar proposals, Ohio presents a uniquely advantageous case due to its rich aerospace heritage, lower operational costs, and central role in the nation’s technology and defense sectors,” read the letter, signed by Ohio Republican Reps. Max Miller, Troy Balderson, Mike Carey, Warren Davidson, Jim Jordan, Dave Joyce, Bob Latta, Michael Rulli, Dave Taylor and Mike Turner and Democratic Rep. Marcy Kaptur. Buckeye State Sens. Bernie Moreno and Jon Husted, both Republicans, signed onto the letter as well.

Florida officials have already made their own proposal for capturing NASA headquarters. Based on this growing lobby effort, it really looks like the Trump administration is serious about scaling down NASA’s headquarters and moving it from the District of Columbia.

ULA pinpoints reason a nozzle fell off a Vulcan rocket side booster during last launch

9:11 am

During a press briefing earlier this week, ULA’s CEO Tory Bruno noted that a manufacturing defect was the reason a nozzle fell off one of the two solid-fueled strap-on boosters during the second launch of the company’s new Vulcan rocket.

In a March 12 media roundtable, Tory Bruno, president and chief executive of ULA, said the anomaly was traced to a “manufacturing defect” in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary. “We have isolated the root cause and made appropriate corrective actions,” he said, which were confirmed in a static-fire test of a motor at a Northrop test site in Utah in February. “So we are back continuing to fabricate hardware and, at least initially, screening for what that root cause was.”

The company however still awaits approval by the Pentagon to begin Vulcan commercial military launches. That delay has forced it to shift its first launch in 2025 from Vulcan to an Atlas-5 launch of Amazon’s first set of operational Kuiper satellites. Bruno also revealed during the press briefing that the company has scaled down the number of launches it hopes to complete in 2025 from 20 to 12, with the reduction caused almost entirely by fewer Vulcan launches.

NASA releases Blue Ghost movie landing while Firefly prepares lander to observe solar eclipse of the Moon by Earth

8:54 am

NASA today released a fantastic movie of Firefly’s Blue Ghost lunar lander as it touched down on the Moon on March 2, 2025, taken by four cameras mounted on the underside of its Blue Ghost lunar lander.

I have embedded the movie below.

The compressed, resolution-limited video features a preliminary sequence that NASA researchers stitched together from SCALPSS 1.1’s four short-focal-length cameras, which were capturing photos at 8 frames per second during the descent and landing.

The sequence, using approximate altitude data, begins roughly 91 feet (28 meters) above the surface. The descent images show evidence that the onset of the interaction between Blue Ghost’s reaction control thruster plumes and the surface begins at roughly 49 feet (15 meters). As the descent continues, the interaction becomes increasingly complex, with the plumes vigorously kicking up the lunar dust, soil and rocks — collectively known as regolith. After touchdown, the thrusters shut off and the dust settles. The lander levels a bit and the lunar terrain beneath and immediately around it becomes visible.

Engineers will use this imagery to better anticipate and possibly reduce the amount of dust kicked up during future landings.

Meanwhile, Firefly engineers are preparing the lander to observe tomorrow night’s lunar eclipse, but from a completely different perspective. On Earth we will see the Earth’s shadow slowly over five hours cross the Moon. On the Moon Blue Ghost will see the Earth cross in front of the Sun. Because of our home world’s thick atmosphere, there should be a ring remaining during totality.

Because the Moon will be in shadow during the eclipse, the challenge will be power management, operating the spacecraft solely on its batteries.

SpaceX launches more Starlink satellites but scrubs manned Dragon launch

8:37 am

SpaceX yesterday attempted two launches from its Florida launchpads, but only got one off. First the company placed another 21 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage completed its 22nd flight, landing on a drone ship in the Atlantic.

In the second launch from the Kennedy Space Center, SpaceX had to scrub the launch because of a problem with the hydraulic system operating a support clamp arm. The flight is now rescheduled for no earlier than tomorrow at 7:03 pm (Eastern).

The leaders in the 2025 launch race:

28 SpaceX
11 China
3 Russia
2 Rocket Lab

SpaceX now leads the rest of the world, including American companies, in total launches, 28 to 20.

Graceful isolated dunes at the edge of the sea of dunes that surrounds Mars’ north ice cap

12:44 pm

Graceful isolated dunes on the edge of the dune sea that surrounds Mars' north pole
Click for original image.

Cool image time! The picture to the right cropped, reduced, and sharpened to post here, was taken on January 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have also rotated it so north is up. Labeled simply as a “terrain sample,” it was likely taken not as part of any specific research request but to fill a gap in the schedule in order to maintain the camera’s proper temperature.

In this case the timing allowed the camera team to capture this breath-taking picture of these graceful arching dunes sitting in what is likely the near-surface ice sheet that covers much of the red planet’s high latitudes. That sheet is not pure ice, but a complex mixture of ice, dirt, dust, and sand, covered during the winter by a thin mantle of dry ice.

The isolated dunes appear to be ridges sticking up from that flat terrain, but this impression is probably incorrect, based on the location.

Readers!

My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.

As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!

Chinese man convicted of flying drone over Vandenberg illegally

9:32 am

The Chinese man, Yinpiao Zhou, who was arrested in November when he flew a spy drone illegally over Vandenberg Space Force Base for almost an hour, has now been convicted of a misdemeanor.

A 39-year-old man from Contra Costa County and Chinese citizen, Yinpiao Zhou, pled guilty to a misdemeanor charge in U.S. District Court in Los Angeles Monday morning for flying a drone over Vandenberg Space Force Base, according to the U.S. Attorney’s Office.

Zhou was arrested in December on charges of failing to register an aircraft that was not providing transportation and violation of national defense airspace, based on federal court documents. Following an indictment by a federal grand jury on the two misdemeanor charges, Zhou, under a plea agreement, admitted guilt to one charge—violation of national defense airspace. … The plea agreement stipulates Zhou may face up to one year imprisonment, one year supervised release, and a $100,000 fine.

All the evidence suggests this guy was doing spying for China. For one, he was arrested at the airport as he tried to board a plane back to flee back to China. Second, when confronted by security he lied about his actions, trying to hide the drone. Third, he had an accomplice who security people foolishly allowed to get away, who is still unidentified and still at large (assuming he is even still in the country).

Based on these facts, at a minimum Zhou should be immediately deported after he completes his one year sentence. In the past he would not have gotten off so lightly. He would have been tried as a spy, and hanged.
