  • LISA Pathfinder Mission Paves Way for Space-based Detection of Gravitational Waves (14 Jun 2016)
    LISA Pathfinder (LPF), an ESA-led mission with NASA contributions, has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves: it has reduced non-gravitational forces on the two floating test masses to a level about 10,000 times smaller than drag-free control technologies used on all previous science missions.
  • Happy 4th Birthday to NuSTAR (14 Jun 2016)
    The Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft was launched on a Pegasus XL rocket dropped from a Lockheed L-1011 "TriStar" aircraft flying over the Pacific Ocean near the Kwajalein Atoll on June 13, 2012. Since then it has made over 1660 hard X-ray observations in science mode which have yielded (to date) hundreds of refereed and other publications.
  • Results of 2016 NASA SMD Astrophysics Senior Review of Operating Missions (10 Jun 2016)
    The Astrophysics Division held the 2016 Senior Review in February and March this year.
