Another example of the weird taffy terrain in Mars’ death valley
Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on January 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists label it dimply as “layers in Helles Planitia.” Other scientists have given this strange landscape a much more interesting label, “taffy terrain.” It is found only in the Hellas Basin, the basement of Mars, having the lowest elevation found anywhere on the red planet. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, and here).
Is taffy terrain still viscous, or has it become solidified? That question I think remains unanswered, though pictures taken of the same spot over time do not yet appear to show changes.

Sunspot update: NOAA scientists try to hide how wrong they have gotten things
My monthly sunspot update today will have less to do with the Sun’s sunspot activity itself — which continues to show a very very slow decline from a peak in August 2024 — and more to do with more games-playing by NOAA solar scientists to fool the public into believing they know more than they do.
Below is my annotated version of NOAA’s monthly graph showing the amount of sunspot activity on the Earth-facing hemisphere of the Sun. This graph is significantly different from the graph that NOAA’s scientists have issued for the past few years, with all the changes designed to make it seem as if these scientists’ predictions are on the money, when they have been entirely wrong now for two solar cycles in a row.

Chinese man who used drone illegally over Vandenberg, spying for China, given slap on wrist in sentencing
Yinpiao Zhou, the Chinese man who flew a drone illegally over Vandenberg last fall in order to spy for China, has now been sentenced for his crime.
Yinpiao Zhou was sentenced Monday morning by a U.S. district judge in Los Angeles to four months in prison with a year of supervised released [sic]. He was also ordered to pay a $200 fine and $25 special assessment.
Since Zhou has been held in prison almost four months already, he will likely be released in days for time served.
All the evidence suggests he did this either willingly or unwillingly under orders from China. A second man that was with him while he flew the drone was never identified or arrested, and has likely been allowed to flee the country. Zhou himself tried to flee as well, as he was arrested at the airport as he tried to board a plane back to China. He is a Chinese citizen who is lawfully in the U.S., but having been caught spying it is astonishing that he is being allowed to remain in the country. He should be deported immediately.
Twenty years of Hubble data map one long season on Uranus
Click for original image.
Astronomers using the Hubble Space Telescope multiple times since 2002 have now tracked the changes in its atmosphere during one quarter of its 84 year orbit around the Sun.
The image to the right, reduced and sharpened to post here, shows Hubble’s views across several electromagnetic wavelengths. Uranus’s rotational tilt or inclination is almost 90 degrees, so that it literally rolls on its side as it orbits the Sun. You can see this especially in the bottom two rows. From 2012 to 2022 one pole slowly shifted westward. From the press release:
The Hubble team observed Uranus four times in the 20-year period: in 2002, 2012, 2015, and 2022. They found that, unlike conditions on the gas giants Saturn and Jupiter, methane is not uniformly distributed across Uranus. Instead, it is strongly depleted near the poles. This depletion remained relatively constant over the two decades. However, the aerosol and haze structure changed dramatically, brightening significantly in the northern polar region as the planet approaches its northern summer solstice in 2030.
Since we have not yet observed Uranus over one full year, there are a lot of uncertainties in any conclusions the scientists propose. For one, we don’t know the general atmospheric patterns across all four seasons. For another, any changes seen now might simply be the planet’s weather, random events not directly related to long term climate patterns.
SpaceX launches 28 Starlink satellites; China launches test internet satellite
SpaceX yesterday successfully placed 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.
Thank you from several readers for letting me know that I missed it. This was the company’s first of two launches yesterday, the second of which was the Fram2 manned mission. I was so focused on that I missed the first.
The first stage completed its seventeenth flight, landing on a drone ship in the Atlantic.
China in turn today launched a satellite to test new technology for providing the internet from orbit, its Long March 2D rocket lifting off from its Jiuquan spaceport in China’s northwest. Little information was released about the satellite, and no information was released about where the rocket’s lower stages — using very toxic hypergolic fuels — crashed inside China.
The leaders in the 2025 launch race:
37 SpaceX
17 China
5 Rocket Lab
4 Russia
SpaceX now leads the rest of the world in successful launches, 37 to 30.
SpaceX launches four commercial private citizens on the first manned polar orbital mission
Capitalism in space: SpaceX tonight successfully launched its Resilience capsule carrying four private citizens on commercial manned mission, its Falcon 9 rocket lifting off from Kennedy in Florida.
The first stage completed its sixth mission, landing on a drone ship in the Atlantic. Resilience in turn is on its fourth flight, with the last three all dedicated to commercial flights for private citizens.
The crew is made up of four rookie space-flyers, mission commander Chun Wang (who paid for the flight), vehicle commander Jannicke Mikkelsen, vehicle pilot Rabea Rogge, and mission specialist and medical officer Eric Philips. The plan is for them to stay in orbit from three to five days, circling the Earth in a polar orbit, the first time any humans have flown in space in such an orbit.
As always, the mission, dubbed Fram2 to honor Fridtjof Nansen’s Fram ship that explored the north pole region from 1893 to 1896, touts its many science experiments, but we should not fool ourselves. Its real goal is to provide Wang and his compatriots the thrill of flying in space.
That the flight is attracting relatively little press compared to previous private and NASA missions indicates how routine SpaceX is making its business. It is making space exploration profitable and no longer reliant on government funds. This is a big deal. Too bad most news outlets don’t realize it.
The leaders in the 2025 launch race:
36 SpaceX
16 China
5 Rocket Lab
4 Russia
SpaceX now leads the rest of the world in successful launches, 36 to 28.

March 31, 2025 Quick space links
Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.
- FAA confirms that it has closed its investigation into the seventh flight of Starship/Superheavy
The FAA also noted the flight’s failure posed no safety issues, something that was clear almost immedately.
- Cuba’s state-run press attacks the arrival of Starlink in Cuba, claiming it is a plot by Trump and Musk to “destabilze” the island
In other words, Cuba’s communist dictators don’t like it that its citizens might now have other options for getting information that those dictators don’t control.
- On this day in 1997 Pioneer-10’s mission ended, 25 years after launch
It continued to send signals back through 2003.
Blue Origin completes investigation of the failed landing of New Glenn’s 1st stage
Blue Origin today announced that it has completed its investigation into the failure of New Glenn’s first stage when it attempted to land on a barge in Atlantic during the rocket’s first launch on January 16, 2025.
Our ambitious attempt to land the booster, “So You’re Telling Me There’s a Chance,” was unsuccessful due to our three BE-4 engines not re-igniting properly. Our review confirmed that all debris landed in our designated hazard area with no threat to public safety. The report identified seven corrective actions, focusing on propellant management and engine bleed control improvements, which we’re already addressing. We expect to return to flight in late spring and will attempt to land the booster again.
It is very concerning that the three BE-4 engines that were supposed to relight were unable to do so, especially because this engine was supposedly designed from the start of re-usability.
The next scheduled New Glenn launch in for June, launching NASA’s Escapade Mars orbiters.
CEO of rocket engine startup accused of bankrupting company by misuse of funds
Buyer beware: Christopher Craddock, the founder in 2014 of the rocket engine startup RocketStar, has now been accused by his former CEO of bankrupting the company by the misuse of funds for “pricey jaunts to Europe, jewelry for his wife, child support payments, and, according to the company’s largest investor, ‘airline tickets for international call girls to join him for clandestine weekends in Miami.'”
Onetime stockbroker Christopher Craddock established RocketStar in 2014 after financial regulators barred him from working on Wall Street over a raft of alleged violations. Craddock held the firm out as “an entity that intended to reinvent space exploration,” states a $6 million lawsuit filed by former CEO Michael Mojtahedi and obtained by The Independent.
….according to Mojtahedi’s complaint, RocketStar “is nothing more than a Ponzi scheme… [that] has been predicated on Craddock’s ability to con new people each time the company has run out of money.”
“Craddock recklessly and lavishly misappropriated for his lifestyle almost every cent RocketStar received from investors, running the company into the ground by August 2024,” the complaint says. “At that point, Craddock’s ‘keeping up with the Joneses’ lifestyle caught up with him, investor funds dried up completely, and his house of cards collapsed.”
Whether Craddock was the crook Mojtahedi say he was remains at this moment unproved. In a sense however this is beside the point. This story illustrates one reality about capitalism that no one should ever forget: Be careful with whom you invest your money. Make sure you know their background. And above all, investigate the company thoroughly before investing in it.
It sure appears that the wealthy people who invested in RocketStar did none of this research. They were the con-man’s perfect mark, innocently handing over cash to someone because what he said sounded good. Rocket science however ain’t easy, and merely sounding good is not enough.
