Can nuclear waste help humanity reach for the stars?
With the shortage of plutonium-238 to power space missions, Europe has decided to focus on an accessible alternative material that could power future spacecraft: americium-241.
Rosetta update: Two close flybys of an increasingly active comet
In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.
