There’s a small army of adorable
We know that Mars once had an Earth-like atmosphere dense enough to support liquid water on the surface of the planet, we’ve found the dry riverbeds and the presence of minerals only formed in water to prove it. We’re also pretty sure that the planet slowly lost that atmosphere into the depths of space on account of climate change. What we don’t know is why. And that’s where NASA’s brand new MAVEN satellite comes in.
For nearly three years, the Wide-field Infrared Survey Explorer (WISE) satellite was one of our most potent tools in the search for asteroids, discovering 33,500 of them (more than a dozen of which are potential impact threats) before being placed into hibernation in 2011. But with a new-found interest in asteroid mining
At this very moment, NASA’s Fermi space telescope is up in the sky, zooming around Earth, and doing space stuff like sidestepping Soviet space junk
Over the past decade there’s been a big push for cheaper alternatives to space travel. Blasting man-made objects into orbit has never been a cheap endeavour, and a company called Titan Aerospace thinks gigantic solar-powered drones could even be a far more affordable alternative to launching satellites.
The Earth’s atmosphere is actually a churning sea of fluid, though it’s easy to forget when you’re just hanging out, breathing it all in. This satellite shot of a tiny island in the Pacific shows the spiral trails it leaves as an ocean of air swirls by.
Watching the animation above, it’s hard not to get goosebumps when the the clock hits 2012 and the whole United States goes red. That’s what it looks like from space when the Earth is parched.
In the 1980s, the US Air Force only knew about roughly 5,000 pieces of space debris orbiting our planet. By 2010, that number had tripled to 15,639 objects. And our current space trash tracking system can’t even detect some of the smaller bits zipping around up there. That’s why the USAF is developing a new iteration of the venerable "Space Fence" that’s both more precise and more cost effective than its predecessor.
How NASA Predicts the Weather
Posted in: Today's ChiliAmerica’s current combined fleet of civilian and military weather monitoring satellites are quickly nearing the end of their operational life spans. It’s a big deal; these satellites provide accurate weather reports for a lot of major government agencies including NASA, NOAA, and the Department of Defense (not to mention our allies). But while the DoD scrambles to replace its aging Defense Meteorological Satellite Program and the Europeans are launching their own HD weather stations
Russia’s radio telescope, Speckt-R, currently holds the record for the largest satellite orbiting Earth, weighing in at around 11,000 pounds. But thanks to the magical product designers at Postlerferguson, you can now fit a Speckt-R on your desk—along with three other iconic unmanned spacecraft.
