  Science drives exploration and nowhere is that more evident than through our discoveries about Mars. From Apollo to the Curiosity rover, the pace of scientific exploration will allow us to answer the question: Are We Alone?
  Dr. John Grunsfeld, our associate administrator for Science and former space shuttle astronaut discusses the path to landing humans on Mars.

  Our pilot Jim Less and videographer Lori Losey refuel their F-15D #897 aircraft from a KC-135 refueling tanker. The F-15D Eagle aircraft flies for research support and pilot proficiency. Our research support aircraft NASA's Armstrong Flight Research Center are commonly called chase planes and fill the role of escort aircraft during research missions.

  A full mission dress rehearsal was held for the Low-Density Supersonic Decelerator (LDSD) project today at the U.S. Navy Pacific Missile Range Facility (PMRF) in Kauai, HI. The ‪#‎LDSD‬ crosscutting technology demonstration mission will test breakthrough entry, descent and landing technologies that will enable large payloads to be landed safely on the surface of Mars. The second flight test of LDSD will be attempted on Tuesday, June 2, launching a rocket-powered, saucer-shaped test vehicle into near-space. Mission blog: http://blogs.nasa.gov/ldsd

  The same GPS technology that helps you get where you’re going in a car will soon be used in space to improve hurricane forecasting. The technology is a key capability in a our mission called the Cyclone Global Navigation Satellite System (CYGNSS) currently in development.
  CYGNSS, set to launch in 2016, will use eight micro-satellites to measure wind speeds over the ocean, increasing the ability of scientists to understand hurricanes. For more on the mission, visit: http://www.nasa.gov/cygnss

  A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the quantum nature, or “foaminess” of spacetime at extremely tiny scales. Details: http://go.nasa.gov/1GJv25G

  A billowing plume of steam signals a successful 450-second test of the RS-25 rocket engine today! RS-25 engines tested on the stand will power the core stage of our new rocket, the Space Launch System (SLS), which is being developed to carry humans deeper into space than ever before. This is another step on our ‪#‎JourneyToMars‬!
