#ANSMET expedition complete! Team spent 5 weeks in #Antarctica searching for #meteorites!

#ANSMET 2015/2016 expedition complete! This amazing team, like so many others before them, spent five weeks in Antarctica (Miller Range) searching for meteorites in what most would consider bitter cold conditions. Think these team members would want to do this again next year?? Ask any one of them the next time you see them and see what they say! How about you – would you want to search for meteorites in Antarctica?

Now that this year’s mission is complete, the collected samples will be transported to our #NASA_Curation Meteorite Laboratory in Building 31 at the NASA Johnson Space Center in Houston, TX. We can’t wait to receive this year’s fabulous finds that through research and analysis, will help scientists better understand the history of our solar system! #RocksFromSpace

#ANSMET team continues their search for #meteorites in the #MillerRange in #Antarctica

This season’s #ANSMET team continues their search for meteorites in the Miller Range. The team searches for meteorites both large and small. Our very own @NASA_ARES team member, Cindy Evans, is seen here “face to the ice” searching for meteorites. As a sample is deemed worth collecting, a team member takes a photo of the sample with a counter/image scale device hovering above it. The sample is recovered using tongs and is put into a Teflon bag provided by #NASA_Curation. Once the sample is in the bag, the unique identifying number, embossed on a metal tag, is affixed to the sample bag (without touching the sample). The team did a midseason inventory (Nina and Morgan in bottom right image) and as of January 7, 2016, they have recovered a total of 392 samples….but their search continues!

#Curiosity conducts first in-depth study of an active #SandDune on another planet (#Mars)

Curiosity is currently performing the first in-depth study of an active sand dune on another planet. The rover is investigating a dune called ‘Namib,’ which is part of the Bagnold Dunes along the northwestern base of Mount Sharp. These images were taken by Navcam and show the slip face of Namib Dune, which is ~13 feet high. The slip face of a dune is the steep, downwind side down which sand grains cascade from the brink of the dune. Images taken from orbit show that some of these dunes move up to 3 feet per Earth year. Mars has much less gravity and a much thinner atmosphere than Earth, which affects the movement of sediments on the surface. Curiosity’s dune campaign will help scientists better understand how wind on Mars transports and sorts sand grains.
