On September 24 this year, a NASA capsule parachuted down to Earth carrying a precious cache of material grabbed from an asteroid. The space agency has now revealed images and a preliminary analysis of the space rocks it found after lifting the lid off that capsule.

The mission to the asteroid was called Osiris-Rex, and in 2020, it collected a sample of material from the asteroid Bennu. Afterward, it traveled back to Earth and released the capsule containing the rocks into our atmosphere three weeks ago.

The fine black dust and small coal-like rocks shimmering in the capsule are beautiful—and somewhat unassuming. But this handful of space rock has the potential to answer questions about not only how the Earth was created, but also how water arrived here and how life got started.

After spending more than a year in space, Frank Rubio now has to get used to that pesky thing Earthlings call gravity.

"Walking hurts a little bit the first few days, the soles of your feet and lower back," he said at a news conference Friday at NASA's Johnson Space Center in Houston, Texas.

Throughout the 20th century, multiple proposals have been made for the crewed exploration of Mars. These include the famed "Mars Project" by Werner von Braun, the "Mars Direct" mission architecture by Robert Zubrin and David Baker, NASA's Mars Design Reference Mission studies, and SpaceX's Mars & Beyond plan. By 2033, two space agencies (NASA and the CNSA) plan to commence sending crews and payloads to the Red Planet. These and other space agencies envision building bases there that could eventually lead to permanent settlements and the first "Martians."

This presents several major challenges, not the least of which have to do with exposure to radiation, extreme temperatures, dust storms, low atmospheric pressure, and lower gravity. However, with the right strategies and technology, these challenges could be turned into opportunities for growth and innovation. In a recent paper, a Leiden University researcher offers a roadmap for a Martian settlement that leverages recent advancements in technology and offers solutions that emphasize sustainability, efficiency, and the well-being of the settlers.

NASA's goal to reduce the costs of the powerful Space Launch System rocket for its Artemis program by 50% was called "highly unrealistic" and a threat to its deep space exploration plans, according to a report by NASA's Office of the Inspector General released on Thursday.

The audit says the costs to produce one SLS rocket through its proposed fixed-cost contract will still top $2.5 billion, even though NASA thinks it can shrink that through "workforce reductions, manufacturing and contracting efficiencies, and expanding the SLS's user base."

"Given the enormous costs of the Artemis campaign, failure to achieve substantial savings will significantly hinder the sustainability of NASA's deep space human exploration efforts," the report warns.

Already, the Biden administration is requesting its largest NASA budget ever for the next fiscal year, although a Republican-led U.S. House is likely to kneecap some of NASA's requests.

The audit looked at NASA's plans to shift from its current setup among multiple suppliers for the hardware to a sole-sourced services contract that would include the production, systems integration and launch of at least five SLS flights beginning with Artemis V currently slated for as early as 2029.

Canadian-French astrophysicist Hubert Reeves, who was renowned for his work popularizing space science, died Friday aged 91, his son said in a post on Facebook.

"My whole family joins me in the pain of having to announce that our dear father has gone to join the stars," Benoit Reeves said.

The history of the universe was Reeves' life passion—he famously said that "to look far is to look early," evoking the concept of space-time—and he was also an ardent defender of planet Earth.

Born in Montreal on July 13, 1932, his thirst for knowledge began at a young age.

At night at their home in Quebec, Reeves and his family would go out to admire the sky, where he first learned to recognize constellations using a cardboard sheet.

It's unlikely to be a bad omen, but NASA's mission Psyche is currently due to launch on Friday 13 October. Lifting off at 10:19 EDT on a SpaceX Falcon Heavy rocket, it faces a perilous journey and isn't scheduled for arrival at its namesake asteroid, 16 Pscyhe, until 2029.

Asteroid 16 Psyche (meaning "soul" in Greek) was discovered in 1852 and is named after an ancient Greek princess who married Eros (the namesake of another asteroid). It orbits the sun in the main asteroid belt between Mars and Jupiter, at approximately three times the distance from the sun as Earth. It is a massive M-type asteroid (M stands for "metal-rich"), over 230km across.

Astronomers have to be careful with the term metal though, as in stellar physics "metallicity" means anything heavier than helium. In this case though, we are talking about metals such as iron and cobalt.

To give an idea of scale, if the sun was shrunk down to the size of an official NBA basketball, then the asteroid's diameter would be about the same size as the thickness of three pieces of paper (0.3mm), and located at a distance of 161 meters away.
