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.

The Recently Created iSpace Crater Has Been Spotted

It doesn’t look like much, but NASA’s Lunar Reconnaissance Orbiter recently spotted the small crater made by the crashed ispace lunar lander named Resilience. The Japanese lander crashed on the Moon’s surface earlier this month after the company’s second try at a lunar landing.

The Moon is littered with debris and pockmarks from various successful and failed missions. The Apollo crew alone left enormous amounts of trash, debris, and space equipment scattered around the Moon. The Russians also left quite a bit of space equipment on the Moon many years ago, as well as its most recent Luna-25 mission, which crash-landed.

We can only hope that the Artemis mission will soon enough be adding to the equipment on the Moon without the drama of crash landings.

Pic of the Week: Mars or Bust?

As shown in the image above, SpaceX lost one of its Starships yesterday in a massive explosion at the Brownsville, Texas Starbase, making the Moon and Mars seem even farther away. Fortunately, no one was injured during this failed test firing of the Starship 36 rocket engines.

We should expect some problems along the way, but the trend is going backwards for Mr. Musk.

In a press release, SpaceX stated:

Engineering teams are actively investigating the incident and will follow established procedures to determine root cause. Initial analysis indicates the potential failure of a pressurized tank known as a COPV, or composite overwrapped pressure vessel, containing gaseous nitrogen in Starship’s nosecone area, but the full data review is ongoing. There is no commonality between the COPVs used on Starship and SpaceX’s Falcon rockets.

In separate comments, Mr. Musk initially stated:

Just a scratch.

Yes, the scratch heard round the world.

A Day in Astronomy: Beginnings and Ends

On this day in 1963, Valentina Vladimirovna Tereshkova from the USSR became the first woman in space. She flew solo on the Vostok 6 for three days. It was her first and last time in space. Her importance as a symbol for women and the USSR meant she would never fly again lest something happen to her.

She was quoted as saying:

They forbade me from flying, despite all my protests and arguments. After being once in space, I was desperately keen to go back there. But it didn’t happen.

On this same day in 1977, German-American Wernher von Braun passed away. As the chief designer of the Saturn rockets that took men to the Moon, he was to see all of the Apollo missions before his death.

He is also quoted as saying:

I’m convinced that before the year 2000 is over, the first child will have been born on the moon.

It is unlikely he would have believed that it would be another 50 years before we found our way back to the Moon.

Space Stories: Spirals in the Oort Cloud, Killer Asteroid Heading Towards Moon, and Starlink Messes Up Astronomy

—NDTV: “Visual Glitch Leads To Accidental Discovery Of Spiral In Mysterious Oort Cloud“

Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical. But during the pre-production of their new space show, “Encounters in the Milky Way,” they noticed a strange spiral pattern in the middle of the cloud. The show, which premiered on Monday at New York City’s Hayden Planetarium, featured a computer-generated visualisation of the Oort Cloud on the dome. The team was reviewing the animation when they noticed what appeared to be a spiral structure inside the typically spherical cloud shape.

—Daily Mail: “NASA Issues Urgent Update on ‘City Killer’ Asteroid Heading Towards the Moon in 2032“

The ‘city killer’ asteroid 2024 YR4 may not be on a collision course with Earth anymore. But NASA has raised the odds of it hitting the moon in just seven years’ time. According to the space agency, there’s now a 4.3 per cent chance that 2024 YR4 will smash into the moon on December 22, 2032…The impact event would be the first time scientists could watch a known asteroid create a lunar crater in real-time.

—New Scientist: “Starlink Satellites are Leaking Radio Signals that May Ruin Astronomy“

SpaceX’s Starlink satellites are leaking radio waves to such an extent that it could threaten our ability to study and understand the early universe, say astronomers. Interference from the thousands of Starlink satellites in orbit, where they provide a global internet service, has been a continuing concern for astronomers, who say that the radio emissions from the craft could affect sensitive telescopes that observe distant, and faint, radio sources. SpaceX has worked with astronomers to try to prevent this interference, by switching off their internet-transmitting beams when they fly over key telescopes, but it turns out that this isn’t enough.
