5 Min Read NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of [...]

Astronaut Suni Williams monitors an Astrobee robotic free-flyer outfitted with tentacle-like arms containing gecko-like adhesive pads as it grapples a “capture cube.”NASA Free flying robotics and space agriculture topped Tuesday’s research schedule as the Expedition 72 crew helps advance the space industry. The International Space Station will also see the departure of a cargo craft [...]
2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft. Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is [...]
