The lack of Martian methane and the search for extraterrestrial life

Joel Achenbach writes about the search for life off earth and the recent measurement by the Curiosity Mars rover (see earlier post) that found no significant level of methane in the atmosphere : On Mars, no proof yet, but scientists’ search for extraterrestrial life continues – The Washington Post.

The lack of methane does not mean there cannot be subterranean life on Mars. Just that it is not the sort of bacteria that generates methane. The previous indications of methane were exciting because it would have been a fairly strong signal for life: Mars Science Laboratory | Mars rover gives negative result on Mars methane – Spaceflight Now.

Sci-Tech: Hyperloop update + Better Li-ion battery + Tesla patents hybrid battery system

A study of Elon Musk’s hyperloop super fast mass transit concept finds that it appears to be feasible: Hyperloop sounds crazy … but simulation says it just might work – NBC News.com

A reader points to this article about a project that could triple the energy density of Li-ion batteries with their new composite cathode:  Solid State Batteries could double the range of electric cars – NextBigFuture.com.

Seems like there have been announcements every few months for years from companies announcing big increases in Li-ion batteries with improved anodes/cathodes. Hope some of them finally get to market soon.

Meanwhile, Tesla Motors Inc patents a system that combines ” a standard lithium ion battery along with a metal-air battery pack”:  Tesla patent describes hybrid battery pack system for EVs – Phys.org

2001: A Space Odyssey with live NY Philharmonic score

Would have been great to watch “2001” with a live orchestra playing the soundtrack: New York Philharmonic Plays ‘2001 – A Space Odyssey’ – NYTimes.com.

Maybe this will happen someday at Wolf Trap, which just had a similar orchestral performance for Lord of the Rings: The Fellowship of the Rings.

James Lovell backs commercial lunar ventures + Space policy roundup

Jim Lovell of Apollo 13 fame now backs the commercial approach to space development: Back to the Moon, Commercially – SpaceNews.com.

Some in Congress are at this very moment talking once again about forcing NASA to establish a program to sustain a human presence on the Moon. I, unfortunately, am not optimistic as we have been here before.

But there is hope. The private sector is stepping up to meet the challenge: an ambitious startup, the Golden Spike Co., is leading the way in creating commercial models to mount human expeditions to the surface of the Moon for nations, companies and individuals.

Until now I have been very doubtful and indeed critical of many existing commercial space ventures that are largely funded by taxpayer dollars. But after several meetings with Golden Spike executives, including the chairman of its board — my old friend — former Apollo Flight Director Gerry Griffin, I became convinced that we truly are on the cusp of a brand new era of commercial lunar space travel.

He has become an advisor to Golden Spike, which is developing a system architecture to enable human missions to the Moon at a small fraction of what NASA’s Constellation program  would have cost. Their mission architecture combines existing rockets and in-space transports with new landing/return vehicles and surface systems.

Lovell probably won’t be invited back to any Congressional hearings on space.

Perhaps Apollo 17 astronaut Gene Cernan, who has repeatedly dissed commercial approaches to human spaceflight, will be the next one to come around.

[ Update: Stephen C. Smith gives the background story to Lovell’s new views on commercial spaceflight: Jim Lovell Joins NewSpace – Space KSC.]
