Payback time.
DART is a test of the kinetic impactor technique, a potential method to deflect an asteroid on course to impact the Earth. Kinetic impactors are one of only a small number of approaches we think are mature enough to deploy in the near future if they are needed (though we hope they won’t be). The most powerful asteroid-deflection technique is the use of a nuclear device. While such a device makes for good (and bad) sci-fi movies, there is widespread desire to develop alternate techniques.
The kinetic impactor concept is rather straightforward: ram the threatening object with a spacecraft and change its orbit so that it misses our planet. In theory, we could heave ever-larger masses at ever-faster speeds to deflect ever-larger objects. However, we think there is a practical limit — we don’t want to break up an incoming object into several pieces, lest we replace one big impact with multiple, only-slightly-smaller impacts. Exactly where that tradeoff lies is still uncertain, but we believe we can keep an object intact if we change its speed by less than the object’s own escape speed. In other words, since we think a lot of these objects are loose aggregates of gravel held together by gravity, we don’t want to shove so hard that we accidentally overcome that weak gravity and disperse the gravel.

SpaceX to Launch Japanese Startup’s Lunar Missions
Posted by Genevieve Klien in categories: robotics/AI, space travel
A Japanese startup called Ispace is shooting for the moon, and SpaceX is going to help. The company wants to lead the charge in the search for large water ice deposits on the lunar surface, and it has two missions planned to make it happen. Both missions, currently slated for 2020 and 2021, will fly on SpaceX rockets.
Ispace was among the companies competing for the Google-backed Lunar Xprize — it funded the Japanese “Hakuto” team. That challenge to land a rover on the moon dragged on for years as the list of competitors dwindled until the last team failed to secure a place aboard an Indian rocket. Ispace didn’t make it that far, but it was in the final five. Google declined to extend the cash prizes (totaling $25 million) in March of this year after pushing back the deadline several times as teams struggled to get their robots launched.
Ispace isn’t letting that failure bog it down. The first of its two planned lunar missions will consist of an orbital module. The second will be more ambitious with a pair of rovers going all the way to the surface. These are mainly technology demonstration missions rather than true ice scavengers, though.
