See the NASA Mars InSight seismometer level itself out

first_imgEnlarge ImageNASA’s InSight mission set this seismometer on the ground in December. NASA/JPL-Caltech NASA’s InSight mission has a way of making you feel like you’re standing on Mars. Some vivid new images show the latest steps in deploying the lander’s seismometer as the space agency gets ready to listen for marsquakes.InSight gently placed the seismometer on the Mars surface in December using a robotic arm, but it was sitting at a slight angle. On Sunday, NASA shared a before-and-after look at the seismometer leveling itself out. You can see the cable that connects the instrument to the lander.

There’s still some more instrument prep to do, but it’s looking good. pic.twitter.com/FlEsAKjzTT— NASA InSight (@NASAInSight) January 4, 2019 I’ve released the slack in my cable so it won’t flutter as much in the wind and pull on the seismometer. Keeping it still will help as I listen for #marsquakes. pic.twitter.com/8NJ9S4gD9i— NASA InSight (@NASAInSight) January 7, 2019 To get ready to record #marsquakes, my seismometer has been leveling itself out and adjusting its internal sensors. It’s always good to be centered and balanced. pic.twitter.com/2A6mpeLNKj— NASA InSight (@NASAInSight) January 6, 2019 Tags 22 Photos The instrument moves slightly between the two frames of the GIF. The InSight team reports the seismometer is adjusting its internal sensors. It’ll also receive a wind and thermal shield to protect it while it listens for activity from the interior of Mars.On Friday, NASA showed how the lander’s arm and claw was able to let go of the seismometer before it leveled itself.  These little Mars movies are giving space fans a fabulous view of InSight’s delicate and ambitious work. We can soon look forward to learning more about the red planet’s stomach rumblings.  NASA InSight lander rocks its journey to Mars: A view in pictures Post a comment InSight landed on Mars in late November to investigate the planet’s vital signs and learn more about how rocky planets are formed. “The seismometer is the highest-priority instrument on InSight: We need it in order to complete about three-quarters of our science objectives,” said Bruce Banerdt, InSight principal investigator.NASA made an additional adjustment to its seismometer deployment. The InSight team tweeted on Monday that the mission has “released the slack in my cable so it won’t flutter as much in the wind and pull on the seismometer.” NASA Spacelast_img read more

T rex was actually bigger than we thought

first_img3:36 This is what would happen if we still had dinosaurs 15 Photos The new conclusions are based on a 66-million-year-old skeleton found in Canada in the early ’90s. Roger Harris/SPL/Getty The undisputed king of the dinosaurs, Tyrannosaurus rex, is even bigger than we once believed.That’s according to new research conducted on “Scotty,” a 66-million-year-old T. rex skeleton first discovered in Canada in 1991. A team of paleontologists at the University of Alberta measured up the skull, hip and limbs of Scotty and suggested that it had a living weight of almost 20,000 pounds (approx. 8,800 kilograms).With that kind of weight, the monstrous ancient lizard would be up there with the largest terrestrial animal currently alive, the African bush elephant, which can weigh up to 26,000 pounds.”This is the rex of rexes,” Scott Persons, lead author of the new study, said in a statement. Tags 5 Sci-Techcenter_img The skeleton was discovered in the western Canadian province of Saskatchewan, encased in sandstone. It took 10 years of fine excavation work to extricate the fossil and now scientists have finally been able to stitch together a picture of Scotty as he would have been 66 million years ago.The findings were published in the journal The Anatomical Record on March 21. The research team describes Scotty as “exceptionally large” and “robust”, which in reality means he was an absolute unit.Making Scotty even more unique is the fact that it is the oldest T. rex skeleton discovered and was likely in his early 30s when he died — which is a pretty good run for the theropods because as far as we currently know, they lived to between 20 and 30 years. By studying one of the major leg bones, the research team could determine that Scotty was a mature T. rex.And in his time, he’d seen things — he bore the marks of a fair few scuffles.”Riddled across the skeleton are pathologies — spots where scarred bone records large injuries,” said Persons.Scotty takes the crown for biggest ever ancient lizard from Sue, a wonderfully preserved T. rex skeleton discovered in South Dakota in 1990. Sue’s estimated weight is around 400 kilograms less than that estimated for Scotty, but with around 90 percent of that skeleton recovered, she is still the most extensive T. rex specimen ever found.
