After many years of people hoping and waiting, NASA has announced that a new mission to Europa has successfully completed its first major review by the agency and now is entering the development phase, known as formulation. In other words, we are finally going back to Europa!
The debate over whether Mars used to be warmer and wetter or colder and wetter earlier in its history has been a long and contentious one. Now, a new study suggests it may be the latter, that Mars was indeed wetter, as overwhelming evidence has already shown, but that it was still a rather cold and icy climate overall.
For the first time, impact glass has been detected on the surface of Mars; the discovery not only provides new information about the formation of impact craters, but might even offer clues to the possibility of ancient life on the Red Planet. The discovery was made by the Mars Reconnaissance Orbiter (MRO) spacecraft.
An exciting new development in planetary exploration was announced yesterday: NASA has chosen the science instruments which will be included in a new mission to Jupiter’s moon Europa. For those advocating and supporting such a mission, this is welcome news indeed. Europa’s subsurface ocean has become a prime target in the search for possible life elsewhere in the Solar System, and this mission may finally help to answer long-standing questions about this fascinating moon.
Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, should that evidence be found by future rovers or landers.
