The Rosetta Orbiter update 03-31-2015

 The Rosetta Orbiter continues its studies of comet 67-P/CG.

 So far the spacecraft discovered the water on the comet is unlike that on Earth.  This has scientists questioning the theory that Earth's water was delivered by comets.

Nitrogen atoms are now found by Rosetta in the comet's outgassing.  This is the first time the element has been discovered since Rosetta began its studies.

The Lander Philae is still silent.  Mission operators still hold out hope the lander will get enough sunlight to recharge its batteries and renew studies of the comet's changing surface.

In other news, the Dawn spacecraft is in orbit around the planetoid Ceres.  It is mapping the surface features of this body which scientists think is about 25 percent water.
