NASA - National Aeronautics and Space AdministrationPasadena, CA – Construction is now complete on the first of the two satellites for NASA’s Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, planned for launch in the December 2017/January 2018 timeframe.

The satellite, built by Airbus Defence and Space at its manufacturing facility in Friedrichshafen, Germany, will spend the next several months undergoing testing at the IABG test center in Ottobrunn, near Munich. The second GRACE-FO satellite will be ready for testing in the near future.

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) finishes it’s 2nd Year in Space

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, a premier black-hole hunter among other talents, has finished up its two-year prime mission, and will be moving onto its next phase, a two-year extension.

“It’s hard to believe it’s been two years since NuSTAR launched,” said Fiona Harrison, the mission’s principal investigator at the California Institute of Technology in Pasadena. “We achieved all the mission science objectives and made some amazing discoveries I never would have predicted two years ago.”

Artist's concept of NuSTAR on orbit. NuSTAR has a 10-m (30') mast that deploys after launch to separate the optics modules (right) from the detectors in the focal plane (left). The spacecraft, which controls NuSTAR's pointings, and the solar panels are with the focal plane. NuSTAR has two identical optics modules in order to increase sensitivity. The background is an image of the Galactic center obtained with the Chandra X-ray Observatory.
