Earth's Water Is Much Older Than the Sun, Carnegie Institution for Science

"Our findings show that a significant fraction of our solar system's water, the most-fundamental ingredient to fostering life, is older than the Sun, which indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems," Alexander said."

Water On Earth Is Older Than Our Sun, University of Exeter

"A pioneering new study has shown that water found on Earth predates the formation of the Sun -- raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy. The ground-breaking research set out to discover the origin of the water that was deposited on the Earth as it formed."

Keith's note: This is a rather profound finding - the sort of thing that would make Carl Sagan excoted - something that you'd think a lot of people would like to know about. The Carnegie Institution for Science notes: "This research was supported by the NSF, the Rackham Predoctoral Fellowship, NASA Astrobiology, NASA Cosmochemistry and NASA.". Yet no mention is made at @AstrobiologyNAI,,, or at The word "inept" once again comes to mind with regard to NASA's Astrobiology program.

NASA Still Won't Look For Existing Life on Mars (update), earlier post

Keith's 31 July note: I obviously expected Jim Green to answer in the same cautious way that NASA has always answered this question - one I have asked again and again for the nearly 20 years. Instead, Green launched into a detailed description of all the things that the Mars 2020 rover could detect that have a connection with life. Much of what he said clearly referred to extant / existing life. Now THAT is cool. To clarify things I sent the following request to NASA PAO "Can the Mars 2020 rover detect extant/existing life on Mars?  Will NASA be looking for extant/existing life on Mars?" Let's see how they respond.

Keith's 3 Sep update: Well it has been more than a month. Dwayne Brown from NASA SMD PAO specifically asked media reps who were on the telecon to send him any questions via email they might have and that he'd get an answer back to them. I haven't heard a thing from him since I sent him the email he requested (wth cc: to SMD management). So much for his promises. Either NASA cannot/will not answer this rather simple question or it is not on Dwayne's priority list right now. I sent additional requests via email to NASA SMD and PAO last week. Still no response.
