China released a new white paper on its policy and activities in space, outlining ambitious deep space exploration, human spaceflight and space science projects as major priorities for the years up to 2020 and beyond.
SpaceX's plans to colonize Mars differ considerably from NASA's Journey to Mars ambitions. But direct comparison is difficult. SpaceX is able to wipe the slate clean and start fresh with a bold new approach to humans in space. NASA has no such luxury, and must use existing pieces and people to make their goals a reality.
A difficult but necessary decision by ESA and Roskosmos to postpone the launch of the ExoMars rover from 2018 to 2020 raises a question about the fate of other planetary exploration programs in the pipelines of both space agencies.
At a recent meeting of an advisory group for NASA, the Committee on Astrobiology and Planetary Science (CAPS), Jim Green, the head of NASA’s Planetary Science Division, and Barry Goldstein from the Jet Propulsion Laboratory, provided updates on plans to explore our solar system's ocean worlds.
This past week brought to the fore two challenges for NASA’s managers as they try to enable the richest possible mix of coming planetary missions. At stake are whether the agency will be able to select two Discovery missions from the current competition, and whether there will be the possibility of a mission selected for Enceladus and/or Titan in the next decade.
NASA announced the first-round selections for its next Discovery mission today. A total of five planetary mission concepts -- three targeted at asteroids, two at Venus -- will move to the next stage of the competition.
