Fantasyland: Turkey to establish its own spaceport

10:11 am

If you believe this I have a bridge I can sell you cheap: According to Turkey’s state-run press, the Turkish Space Agency is now researching locations for its own spaceport, either in Turkey or in some other nearby nation such as Somalia.

According to information provided by relevant government agencies, efforts are ongoing to select a suitable location for the facility. Discussions are underway with countries near the equator, including Somalia, to maximize launch efficiency.

…Once operational, the spaceport will support independent satellite launches, marking a major step in Türkiye’s ability to access space without relying on foreign platforms.

Recently Turkey launched its first home-built smallsat on a SpaceX Falcon 9 rocket. It seems its space agency now believes it can quickly whip up its own rocket and launch it from a quickly built spaceport, likely in another country.

This announcement is nothing but government blather published to puff up these government officials so that they can garner more funding and build bigger more palatial offices.

Iran accelerates plans for new coastal spaceport

10:01 am

Iran's spaceports

According to Iran’s state-run press, the government is about to begin the next construction phase for its proposed new coastal spaceport near the city of Chabahar.

The head of the Iranian Space Agency has announced that the second phase of the Chabahar spaceport for semi-heavy liquid-fueled launchers is to be inaugurated in the current Persian calendar year. Hassan Salarieh said on Tuesday that the first phase of the Chabahar spaceport is for solid fuel launchers and is expected to be inaugurated this year (which started March 21), adding that adequate studies were conducted regarding the second phase of the site in previous years and the new phase for semi-heavy liquid fuel launchers is to be opened during the year.

The details are very vaguely words. Will launches of solid-fueled rockets begin this year, or construction? Earlier reports had promised the first launch from Chabahar would occur in March 2025. That clearly has not occurred.

This spaceport will supplement Iran’s older Semnan launch facility in the country’s interior, from which all previous Iranian launches have occurred.

ULA and Amazon schedule first Kuiper satellite launch for April 9, 2025

9:49 am

The launch of the first 27 satellites in Amazon’s 3,200-plus satellite Kuiper internet constellation has now been scheduled for April 9, 2025, using ULA’s Atlas-5 rocket lifting off from Cape Canaveral.

The Kuiper constellation, intended to compete directly with SpaceX’s Starlink constellation, was first conceived at about the same time as Starlink. Since then — while Amazon moved slowly launching only two test satellites — SpaceX launched thousands and signed up millions of customers, grabbing market share that it will be difficult for Kuiper to re-capture.

The launch will also be the first in 2025 for ULA, which had hoped to do as many as 25 launches this year with its old soon-to-be-retired Atlas-5 and new Vulcan rocket. The six-month delay in getting the Pentagon to finally certify Vulcan for commercial military launches has put a damper on that plan. Right now ULA will be lucky if it can complete half those launches.

Using new infrared images and data from the Webb Space Telescope, astronomers have further refined the orbit and size of the potentially dangerous asteroid 2024 YR4.

The image of 2024 YR4 to the right was taken by Webb’s mid-infrared camera, and provides information on its thermal surface characteristics.

First, the Webb data narrowed the uncertainty about the asteroid’s size, suggesting it is about 200 feet in diameter. You can read the paper outlining this result here. The data also suggested nature of the asteroid’s surface, which is important in determining its future path. The pressure from sunlight can change the orbits of small asteroids, but figuring out how much is extremely difficult without knowing the rotation of the asteroid and the reflective qualities of its entire surface.

Second, based on this new data, other astronomers are increasingly certain 2024 YR4 will not hit the Earth in 2032, but the odds of it impacting the Moon have now increased to 4%.

Update on the private Fram2 manned orbital spaceflight

9:15 am

The crew of Fram2 in weightlessness

In the past day the crew of the private Fram2 manned orbital spaceflight have released several updates, describing their initial experience in weightlessness as well as releasing some images of themselves inside the Resilience capsule.

First, on April 1, 2025 the mission commander, Chun Wang, the billionaire who paid for the flight, posted a tweet describing how all four crew members experienced space sickness the first day in orbit.

The first few hours in microgravity weren’t exactly comfortable. Space motion sickness hit all of us—we felt nauseous and ended up vomiting a couple of times. It felt different from motion sickness in a car or at sea. You could still read on your iPad without making it worse. But even a small sip of water could upset your stomach and trigger vomiting.

Things however quickly settled down, allowing them to open the nose cone so that they could see out the large cupola window. They released the first images of the Antarctic, and followed soon after with the first images of themselves inside Resilience. The picture to the right, taken by Wang, shows is three crewmates, Jannicke Mikkelsen, Rabea Rogge, and Eric Philips clearly now enjoying the experience of weightlessness.

Still no word on a return date. The mission was initially supposed to last 3 to 5 days. We are now on day three, with no indications of a planned return date.

Senate schedules hearing to review Jared Isaacman’s nomination as NASA administrator

8:59 am

After months of delays, the Senate Committee on Commerce, Science, and Transportation yesterday finally announced it has scheduled for April 9, 2025 the confirmation hearing for Jared Isaacman’s nomination as NASA administrator.

I have previously speculated that the delay in scheduling this hearing was because there was opposition to Isaacman among Republicans both in the Senate and inside the White House, based on his past donations to the Democratic Party as well his previously strong support for Divesity, Equity, and Inclusion in his companies. It appears Isaacman must have eased those concerns when he began face-to-face private meetings with several Senate Republicans in the last two weeks, thus allowing the hearing to be scheduled.

Isaacman has been in Washington in recent days for one-on-one meetings with senators, a standard part of the confirmation process before a formal hearing. That included Sen. Jerry Moran (R-Kansas), who chairs the committee’s subcommittee on aviation, space and innovation, as well as the Senate Appropriations Committee’s subcommittee on commerce, justice and science, which funds NASA.

Moran said in an April 1 social media post that he met with Isaacman and discussed topics such as exploration and “a shared desire to beat our adversaries back to the Moon” as well as work on science and technology at NASA. “I am eager for the Commerce Committee to quickly conduct a confirmation hearing on his nomination to lead NASA,” Moran stated.

It now appears likely that this opposition is dissolving, and that Isaacman’s confirmation is likely.

Starliner’s troubles were much worse than NASA made clear

11:51 am

Starliner docked to ISS
Starliner docked to ISS.

According to a long interview given to Eric Berger of Ars Technica, the astronauts flying Boeing’s Starliner capsule on its first manned mission in June 2024 were much more vulnerable than NASA made it appear at the time.

First, the thruster problem when they tried to dock to ISS was more serious than revealed. At several points Butch Wilmore, who was piloting the spacecraft, was unsure if he had enough thrusters to safely dock the capsule to ISS. Worse, if he couldn’t dock he also did not know if had enough thrusters to de-orbit Starliner properly.

In other words, he and his fellow astronaut Sunni Williams might only have a few hours to live.

The situation was saved by mission control engineers, who figured out a way to reset the thrusters and get enough back on line so that the spacecraft could dock autonomously.

Second, once docked it was very clear to the astronauts and NASA management that Starliner was a very unreliable lifeboat.

ESA isn’t forcing private companies building cargo capsules to hire contractors from all its partners

10:33 am

Capitalism in space: When the European Space Agency (ESA) in May 2024 awarded two contracts to the French startup The Exploration Company and the established Italian contractor Thales-Alenia to develop unmanned capsules for bringing cargo to and from orbit, it also made a major policy change that went unnoticed at the time.

During a press briefing on 23 May [2024], following the Phase 1 awards, ESA Director General Josef Aschbacher explained that the agency would not require participants in the initiative to adhere to its geo-return policy. The policy typically ensures that contracts are distributed among ESA member states in proportion to their financial contributions. “We contract very differently because we will be the anchor customer,” said Aschbacher. “That means we buy a service. We give industry all the freedom to find the best solution technically, but also the best partners, with whomever they want to work with.”

What means is that the two companies, in developing their capsules, have not been required to spread the work out across Europe. Instead, they have been free to do the work entirely in house, or hire just the subcontractors they prefer, from anywhere. As the CEO of The Exploration Company noted, “In plain terms, we choose our suppliers based purely on quality and cost—not because they’re French, Italian, or German. We choose the best supplier for the job.”

In the past, as part of its bureaucratic and political needs, ESA’s “geo-return policy” required every space project to spread the wealth to all of the ESA’s partner nations, in amounts proportional to their financial contributions to the ESA. The result was that every project went overbudget, took too long to complete, and was unrealistically complex. Many projects simply failed because of these issues. Others took decades to get completed, for too much money. And when it came to rockets, it produced the Ariane-6, that is too expensive and cannot compete in today’s market.

This decision last year means that ESA is very slowly adopting the concept of capitalism in space, whereby it acts merely as a customer, buying products that are completely owned and controlled by the seller.

This new policy presently only applies to the development phase of these capsules. Though no decision has been made about the construction phase, involving much more money, ESA publications indicate it will apply there as well.

Though it is taking time, Europe’s space bureaucracy is beginning to accept the idea of freedom and capitalism.

Fram2 passengers take their first pictures of Earth’s polar regions

10:10 am

The Arctic as seen from Fram2

SpaceX yesterday released a short video of the first pictures of the Earth’s polar regions taken by its Fram2 passengers on the capsule Resilience.

The picture to the right is a screen capture from that film, looking out the capsule’s large cupola window in its nose. The capsule’s nosecone can be seen at the bottom, having hinged sideways out of the way during orbital operations.

The tweet provided little information about the images. For example, it did not say which pole was imaged. Since the ground and ice below is dark, we are likely looking at the north pole, which at this time of year is mostly in shadow. You can see what looks like the edge of the ice pack, partly hidden by clouds.

The flight is scheduled to last from three to five days, and is presently in its second day. Not much information from the crew in orbit has at this point been released. I suspect they are simply enjoying their experience in private, since they are not obligated to share it with the world.

Another example of the weird taffy terrain in Mars’ death valley

1:29 pm

More taffy terrain

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

12:00 pm

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

9:19 am

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

9:09 am

Uranus over twenty years
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

8:39 am

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.
