Do I geek out about cool-looking sandstone? You bet. A shallow scouring with my drill’s abrasion bit shows this rock has veins of lighter material inside. Could it hold clues about ancient life? Time for more #SamplingMars. More on “Yori Pass”: go.nasa.gov/3AnIv4Q

I’ve got over a dozen rock cores on board, with many more samples to come. Meanwhile, NASA and @ESA are preparing the extraction team. Check out the bold plan that would bring these samples safely back to Earth in the early 2030s. mars.nasa.gov/msr

A black hole's gravity is so powerful that not even light can escape it. 😱 But on this #BlackHoleFriday, we ask you not to fear the mysterious things in our universe and instead be open to their beauty.

A team of researchers has discovered at least two new minerals never before been seen on Earth in the 15 tonne El Ali #meteorite found in Somalia — the 9th largest ever found. #UAlberta Faculty of Science, University of Alberta UofA EAS Department University of Alberta Museums ualberta.ca/folio/2022/11/…

My collection is growing! 🪨 I’ve now got my 15th rock core: a nice piece of sandstone. Up next, I’m heading back to a nearby dune to break out a new tool – my regolith collection bit – for gathering loose, sandy material. #SamplingMars continues…

This just in - the THIRD new #mineral in the El Ali #meteorite has been approved! Olsenite, KFe4(PO4)3, is named after Edward J. Olsen, the former mineralogy and meteorites curator at the Field Museum of Natural History in Chicago. cbc.ca/news/canada/ed…

Remember that #fireball on Feb 22, 2021 over #yeg and surroundings? You might have picked it up on your doorbell cam! It came from the Oort Cloud! We spotted it on our Fireballs in the Sky cams and helped Denis Vida with getting those data.

Here is your #marssamplereturn scorecard. Samples collected thus far by NASA's Perseverance Mars Rover (thanks to Mapperwocky(@[email protected] and Mastodon)). Green boxes around the samples we are starting to put down in the first sample depot. Depot spot is near the “RV” in “Observation Mountain”.

There is a group of large dark asteroids in the Outer Main Belt that shares properties and history with Ceres: they accreted late (1.5-3.5 Myr after SS formation) and come from the outer Solar System. @drisstakir, @astromaterials, Sean Raymond et al.: nature.com/articles/s4155…

The HAYABUSA2@JAXA spacecraft collected a combined total of 5 grams from two locations on near-Earth asteroid #Ryugu. A new special issue of Science describes lab analyses of the samples, revealing the asteroid's composition, formation process, and history. scim.ag/1Fd

Keep your eyes on the low, western horizon shortly after sunset this week: Jupiter, Mercury, Venus, Uranus, and Mars will line up across the evening sky! 🌟 Use binoculars to see Mercury + Uranus 🌟 Be timely: Jupiter + Mercury will dip below the horizon just 30 min after sunset

How exciting is this! Tomorrow the crew for the #Artemis II mission will be selected! This will bring us one step closer to #Artemis III when humans will return to the surface of the Moon - and when they return they'll have lots of new samples for us to look at 😀 #ToTheMoon
