Collisions in Space

Space is a dangerous place
Something might have hit THEMIS-B

You could fly around forever and never hit a thing

Astronomy News – Considering the volume of bodies circling in the solar system one might think that collisions between bodies in the solar system is commonplace, but in fact collisions between bodies circling in the solar system are relatively uncommon. This is what makes a recent report by NASA of a possible collision of one of their spacecraft with a meteorite a highlight of sorts, or at least something relatively unusual. NASA reported a possible collision between a meteorite and part of the sensitive instrumentation on board their THEMIS-B spacecraft, which is one of the two ARTEMIS spacecraft, at 0605 UT on October 14. Apparently, the flight dynamics data collected on THEMIS-B indicated that it might have been struck by a meteorite, which likely means the meteorite made a slight change in the flight path of the spacecraft. According to NASA, everything is still a go with THEMIS-B’s insertion into Lissajous orbit, and up coming simultaneous measurements of particles and the electric and magnetic fields in two different locations, using both ARTEMIS spacecraft. This will provide astronomers with the first three-dimensional look at how energetic particle acceleration happens near the Moon’s orbit, in the solar wind, and in the distant magnetosphere.
