onjr NASA s Artemis Moon Rover Is Officially Under Construction
Wkhf These Scientists Just Fired The World s Most Powerful LaserAt its current location for inspecting an active sand dune, NASA s Curiosity Mars rover is adding some sample-processing moves not previously used on Mars.Sand from the second and third samples the rover is scooping fromNamib Dunewill be sorted by grain size with two sieves. The coarser sieve is making its debut, and using it also changes the way the treated sample is dropped into an inlet port for laboratory analysis inside the rover.Positioning of the rover to grab a bite of the dune posed a challenge, too. Curiosity reached this sampling site, calledGobabeb,on Jan. 12. It was pretty challenging to drive into the sloping sand and then turn on the sand into the position that was the best to study the dunes,said Michael McHenry of NASA s Jet Propulsion Laboratory, Pasadena, Ca stanley tumbler lifornia. He is the Curiosity mission s campaign rover planner for collectingstanley sverige these samples.Curiosity has scooped up sample material at only one other site since it landed on Mar stanley termoska s in August 2012. It sampled dust and sand at a windblown drift site calledRocknestin October and November 2012. Between there and Gobabeb, the rover collected sample material for analysis at nine rock targets, by drilling rather than scooping. The mission s current work is the first close-up study of active sand dunes anywhere other than Earth. Namib and nearby mounds of dark sand are part of theBagnold Dune Field,which lines the northwestern flank of a layered mountain where Curiosity is examining rock records Iwvw The Disempowering Experience of Flying as a Disabled Person

His new plan doesnrsquo;t reduce tax rates by as much as the original plan, and it also includes some changes that generate tax revenue, but the overall effect should still be a reduction in the amount of money being siphoned out of the economy by Washington.Lower corporate tax rate: The crown jewel of Trumprsquoplan is a 15% corporate tax rate, dramatically boosting U.S. competitiveness and making America a much more attractive place to do business.
