After more than two years in orbit around asteroid Bennu, NASA’s OSIRIS-REx spacecraft is ready to come home. It’s bringing with it a pristine sample of space rocks that geologists here on Earth are eager to study up close. The sample will arrive in September 2023, but we won’t have to wait nearly that long for new data from OSIRIS-REx. Last week, the probe carried out one final flyby of Bennu, in an effort to photograph the sample collection site. The photographs are being downlinked now, and should be here by midweek.
If you’ve been following the OSIRIS-REx mission, you probably already know why scientists are keen to see these photographs, but if you haven’t, hold on to your hats – it’s a wild story.

Geologists love fieldwork. They love getting their specialized hammers and chisels into seams in the rock, exposing unweathered surfaces and teasing out the rock’s secrets. Mars would be the ultimate field trip for many of them, but sadly, that’s not possible.
Instead, we’ve sent the Perseverance rover on the field trip. But if a geologist were along for the ride, what would it look like to them?

You have to be careful what you say to people. When NASA or someone else says that the Perseverance rover will be looking for fossil evidence of ancient life, the uninformed may guffaw loudly. Or worse, they may think that scientists are looking for actual animal skeletons or something.
Of course, that’s not the case.
So what is Perseverance looking for?

On Tuesday, December 1st, at 10:11 EST (07:00 PST) the Chang’e-5 sample return spacecraft landed safely on the Moon. This mission is the latest in China’s lunar exploration program, which is paving the way for the creation of a lunar outpost and a crewed mission by the 2030s. The day after it landed, the Lunar Reconnaissance Orbiter (LRO) passed over the site and acquired an image of the lander.

For the first time in more than 40 years, a robotic spacecraft has blasted off from the Moon – and for the first time ever, it’s a Chinese spacecraft, carrying precious lunar samples back to Earth.
The ascent vehicle for the Chang’e-5 mission fired its engine and rose a region called Oceanus Procellarum at 1510 UTC (11:10 p.m. Beijing time) on December 3rd, the China National Space Administration’s China Lunar Exploration Project reported.
Imagery sent back from the Moon provided a view of the blastoff from ground zero. It was the first successful lunar launch since the Soviet Luna 24 probe took off during a sample return mission in 1976.

When astronauts return to the Moon for the first time since the Apollo Era, they will be tasked with conducting some very lucrative science operations. Like their predecessors, this will include a sample-return mission, where they bring back lunar rocks and regolith for study. There have also been proposals that renewed missions to the Moon bring back samples of lunar ice so scientists can determine where the Moon’s water came from.
And it appears NASA was listening and would like some public input on this! To this end, the NASA Tournament Lab and TechConnect Ventures (a n open-innovation platform) have come together to launch the NASA Lunar Deep Freeze Challenge. Basically, NASA is looking for ideas on how cold samples collected in the lunar polar region could be preserved and kept frozen for the return trip to Earth.

NASA is about to achieve another first for their organization. In about three weeks time, on October 20th, the OSIRIS-REx spacecraft will descend to Bennu’s surface, briefly touch down, and collect a sample from the asteroid. The spacecraft will collect a minimum of 60 grams (2 oz.) of material for return to Earth.

NASA’s OSIRIS-REx is getting closer, physically and temporally, to its primary goal. The spacecraft arrived at Bennu at the end of 2018, and for just over a year it’s been studying the asteroid, searching for a suitable sampling site. To do that, it’s getting closer and closer.

NASA’s OSIRIS-REx spacecraft reached its target, asteroid Bennu (101955 Bennu), on December 3rd, 2018. Since then, the spacecraft has been examining the asteroid’s surface, looking for a suitable landing spot to collect a sample. The problem is, Bennu has a much rockier and challenging surface than initially thought.

NASA has chosen the sampling site for its OSIRIS-REx spacecraft. After narrowing it down to four potential sites and examining them in detail, they’ve settled on one location. Their choice? Nightingale.
