One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on some distant exoplanet. However, the best way to go about that is a subject of much debate. Now, researchers at NASA’s Jet Propulsion Laboratory have come up with a new proposal: a “Chemical Laptop,” a miniaturized portable laboratory which would look for signs of materials associated with life (at least as we know it), such as amino acids.
Looking ahead to future planetary missions, NASA has selected five new science investigations for refinement over the next year. Later, one or two of those missions will be chosen to actually be launched, perhaps as early as 2020. The selections are part of NASA’s Discovery Program, which had requested the proposals in November 2014. Initially, 27 proposals had been submitted, from which the five current finalists were chosen. The five proposals would study Venus, near-Earth objects, an unusual metallic asteroid and Trojan asteroids.
NASA’s Curiosity rover has just reached its third anniversary milestone on Mars, after landing in Gale crater on Aug. 5, 2012, and since then has made some incredible science discoveries, with more to come in the months and years ahead. NASA is celebrating this achievement and you can take part, too!
