Here are some recent space-related stories of interest.

—NASA “NASA Aircraft, Sensor Technology, Aid in Texas Flood Recovery Efforts“

In response to recent flooding near Kerrville, Texas, NASA deployed two aircraft to assist state and local authorities in ongoing recovery operations. The aircraft are part of the response from NASA’s Disasters Response Coordination System, which is activated to support emergency response for the flooding and is working closely with the Texas Division of Emergency Management, the Federal Emergency Management Agency (FEMA), and the humanitarian groups Save the Children and GiveDirectly.

—Newsweek: “China Appears to Pull Off Satellite Feat That NASA Has Never Achieved“

Two remote-controlled Chinese satellites appear to have docked in high orbit to allow refueling and servicing for the first time. The achievement, which has yet to be matched by the U.S, involved autonomous spacecraft Shijian-21 and Shijian-25, completing the task in geostationary orbit earlier this month. Geostationary orbits occur at 22,236 miles above the surface, and are typically used for communications satellites so that they can move with the rotation of the Earth. However, the high orbit and need for satellites to maintain speeds with the Earth’s rotation makes docking extremely difficult.

—Royal Astronomical Society: “Life on Venus? UK Probe Could Reveal the Answer“

The answer to whether tiny bacterial lifeforms really do exist in the clouds of Venus could be revealed once-and-for-all by a UK-backed mission. Over the past five years researchers have detected the presence of two potential biomarkers – the gases phosphine and ammonia – which on Earth can only be produced by biological activity and industrial processes. Their existence in the Venusian clouds cannot easily be explained by known atmospheric or geological phenomena, so Cardiff University’s Professor Jane Greaves and her team are plotting a way to get to the bottom of it. Revealing a new mission concept at the Royal Astronomical Society’s National Astronomy Meeting 2025 in Durham, they plan to search and map phosphine, ammonia, and other gases rich in hydrogen that shouldn’t be on Venus.

Space Stories: Mysterious Signal Solved, Trusting AI in Astronomy, and a New Particle Detected on the Moon

Here are some recent space-related stories of interest.

—Phys.org: “Mysterious Fast Radio Burst Turns Out to be From Long-dead NASA Satellite“

A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant source, but from one circling the planet—a long-dead satellite. The team has posted a paper outlining their findings on the arXiv preprint server…The findings could lead to the development of new tools for studying signals coming from space, whether near or far, and possibly new ways to monitor the movement of dead satellites.

—Futurism: “Nobel Prize Winner Warns About Astronomers Using AI to Make Discoveries“

A team of astronomers say they’ve gleaned the mysterious traits of our galaxy’s black hole by probing it with an AI model. But a pretty big name on the field is throwing a little bit of cold water on their work. Just a little bit. Reinhard Genzel, a Nobel laureate and an astrophysicist at the Max Planck Institute, expressed some skepticism regarding the team’s use of AI, and the quality of the data they fed into the model. “I’m very sympathetic and interested in what they’re doing,” Genzel told Live Science. “But artificial intelligence is not a miracle cure.”

—Swedish Institute of Space Physics: “Swedish-built Instrument Discovers New Type of Particle on the Lunar Surface“

A space instrument, built by the Swedish Institute of Space Physics (IRF), has for the first time detected negative hydrogen ions on the surface of the Moon – a type of particle never seen there before. The discovery was recently published in the scientific journal Nature Communications Earth and Environment.

Space Stories: Kuiper Launch, NASA Workforce Cuts, and Prepping for Moon Landing

—ABC News: “Amazon Launches First Kuiper Internet Satellites, Taking on Starlink“

The first 27 satellites for Amazon’s Kuiper broadband internet constellation were launched into space from Florida on Monday, kicking off the long-delayed deployment of an internet-from-space network that will rival SpaceX’s Starlink. The satellites are the first of 3,236 that Amazon plans to send into low-Earth orbit for Project Kuiper, a $10 billion effort unveiled in 2019 to beam broadband internet globally for consumers, businesses and governments – customers that SpaceX has courted for years with its powerful Starlink business.

—Government Executive: “NASA preparing for steep workforce cuts but hopeful it can avoid more layoffs“

As NASA ramps up plans to return to the moon and, eventually, Mars, it is moving forward with plans to shrink its workforce by incentivizing employees to leave government...NASA officials have told employees they may receive a second “deferred resignation” offer to allow staff to take paid leave until they exit government by Sept. 30, as well as early retirement and buyouts, to incentivize departures from the agency. These options were submitted as part of NASA’s reduction-in-force and reorganization plan, employees who attended the meetings in which the plans were shared said, which all agencies had to turn over to the Office of Personnel Management and the White House in recent weeks.

—NASA: “NASA Marshall Fires Up Hybrid Rocket Motor to Prep for Moon Landings“

To better understand the physics behind the interaction of exhaust from the commercial human landing systems and the Moon’s surface, engineers and scientists at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently test-fired a 14-inch hybrid rocket motor more than 30 times. The 3D-printed hybrid rocket motor, developed at Utah State University in Logan, Utah, ignites both solid fuel and a stream of gaseous oxygen to create a powerful stream of rocket exhaust.

The Internet Satellite Race Continues, Almost

Posted on by onespaceman2000

Amazon hopes to challenge SpaceX’s Starlink system, but not just yet.

The launch planned for earlier this week place 27 internet satellites into orbit as part of Amazon’s Project Kuiper was scrubbed at the last minute. The United Launch Alliance (ULA) launch, scheduled for last Wednesday, was delayed due to bad weather.

If all goes according to plan, Project Kuiper will have about 1,600 satellites in orbit by the middle of next year. That would mean about 80 launches over that period, which seems somewhat unlikely given ongoing delays. In addition to ULA launches, Amazon is booking launches with Arianespace, Blue Origin, and SpaceX. When the project is complete, about 3,200 Kuiper internet satellites will be in orbit.

The Kuiper satellites will compete head-to-head with SpaceX’s Starlink (with its goal of 42,000 satellites) and China’s SpaceSail (with its goal of 15,000 satellites).

A new launch date for the first launch of the Kuiper internet satellites has not been announced yet.

Update: I forgot to mention another competitor – Eutelsat’s Oneweb in the European Union, which already has about 650 Internet satellites in Low Earth Orbit.

Second Update: This story, “Telecommunications Satellites and Space Exploration,” has a nice summary about how we arrived at the current moment with our satellite technology as well as what the future may hold.

Weather Issues Impact SPHEREx Mission, But its Ready Now

One can expect weather issues in Florida, but California? It seems that the west coast also has its issues, per a tweet yesterday from SpaceX:

Due to unfavorable weather at the launch site and an issue with one of the @NASA spacecraft, we are standing down from tonight’s Falcon 9 launch of NASA’s SPHEREx and PUNCH missions. Next launch opportunity is Tuesday, March 11 at 8:10 p.m. PT

Given that the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) observatory mission has gotten this far with all of the challenges along the way, I think a few extra days are okay. NASA is also keen to see the Polarimeter to Unify the Corona and Heliosphere (PUNCH) satellites aloft as well.

Everything is ready to go in less than an hour (8:10 p.m. PDT, 11:10 p.m EDT). If you would like to watch it, you can go to NASA+.

Update: The SPHEREx and PUNCH missions were successfully launched yesterday evening, March 11th.
