NASA’s Europa Clipper Spacecraft’s high-gain antenna undergoes testing

NASA - National Aeronautics and Space AdministrationHampton, VA – NASA says it probably goes without saying, but this isn’t your everyday satellite dish.

In fact, it’s not a satellite dish at all. It’s a high-gain antenna (HGA), and a future version of it will send and receive signals to and from Earth from a looping orbit around Jupiter.

The antenna will take that long journey aboard NASA’s Europa Clipper, a spacecraft that will conduct detailed reconnaissance of Jupiter’s moon Europa to see whether the icy orb could harbor conditions suitable for life. Scientists believe there’s a massive salty ocean beneath Europa’s icy surface. The antenna will beam back high-resolution images and scientific data from Europa Clipper’s cameras and science instruments.

A full-scale prototype of the high-gain antenna on NASA's Europa Clipper spacecraft is undergoing testing in the Experimental Test Range at NASA's Langley Research Center in Hampton, Virginia. (NASA/Langley)

NASA research shows Smoke from Wildfires can Impact Climate more than previously thought

NASA - National Aeronautics and Space AdministrationHampton, VA – The 2017 wildfire season is well underway in the United States with thousands of acres scorched already in Georgia and Florida alone, according to the National Park Service. New research using data collected during NASA airborne science campaigns shows how smoke from this type of wildfire worldwide could impact the atmosphere and climate much more than previously thought.

The study, led by researchers at the Georgia Institute of Technology, found brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun – sometimes cooling the air and at other times warming it.

NASA - National Aeronautics and Space AdministrationHampton, VA – It’s a complex and daunting thing, dreaming up ways to assemble spacecraft in space.

But don’t tell that to a few whip-smart college students — they’re up for the challenge.

In fact, five university teams will soon get the chance to make the case for their in-space spacecraft assembly concepts as part of the 2017 Breakthrough, Innovative and Game-changing (BIG) Idea Challenge.

NASA’s Game Changing Development Program looks for idea for putting spacecraft together in space

NASA - National Aeronautics and Space AdministrationHampton, VA – In the 2017 Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge, NASA is engaging university-level students in its quest to reduce the cost of deep space exploration.

NASA’s Game Changing Development Program (GCD), managed by the agency’s Space Technology Mission Directorate, and the National Institute of Aerospace (NIA) are seeking novel and robust concepts for in-space assembly of spacecraft — particularly tugs, propelled by solar electric propulsion (SEP), that transfer payloads from low earth orbit (LEO) to a lunar distant retrograde orbit (LDRO).
