The White House Office of Science and Technology Policy (OSTP) sent letters to Congress on October 15 spelling out agency responsibilities in the event a Near Earth Object (NEO) is on a collision course with Earth. NEOs are asteroids or comets on trajectories that come close to Earth.
The letters are in response to a provision in the 2008 NASA Authorization Act. The bottom line is that NASA would notify the Federal Emergency Management Agency (FEMA) "in the unlikely event of an impending NEO threat." FEMA would use its existing communications mechanisms to warn state and local officials. The Department of State would notify other countries as needed. NASA would be responsible for notifying FEMA after coordinating with other organizations "within the NEO detection community." The notification would go to FEMA's Operations Center, as well as DOD's Joint Space Operations Center, the State Department, appropriate White House offices, and "other relevant Federal officials and organizations."
But the letters do not solve the larger question of what agency would be in charge of "mitigating" the threat -- deflecting or destroying the NEO. OSTP says only that the government's "assessment of potential mitigation/deflection options is at an early stage of development and not yet ready for implementation...." A recent National Research Council (NRC) report, which also was requested by Congress, provides "helpful insights" into mitigation options, says OSTP, but more analysis and simulation is needed. NASA is designated by OSTP as the lead agency to conduct that work in coordination with DOD, FEMA and other appropriate agencies.
Those agencies are also directed to "conduct outreach with relevant private sector stakeholders and organizations" as well as other countries and multilateral forums.
OSTP Director John Holdren, who signed the letters, made the concluding point that the approach was subject to further review as more information becomes available that "could lead to different philosophies on agency roles and responsibilities in this arena as we continue to consider the most effective way to address these potential threats. It also would be constructive to explore what resources may be needed to support these assessment activities going forward.""
SpacePolicyOnline.com correspondent Laura M. Delgado has a really interesting piece about space commercialization on Space News' guest blog. "A Pop-corn Bred Perspective on Space Commercialization" talks about the "gap" not between the end of the space shuttle and whatever succeeds it, but the gap between the space policy community and the public on the role of the private sector in the future of the space program because their exposure to the topic is through science fiction movies. Take a look!
NASA's Lunar CRater Observation and Sensing Satellite (LCROSS) mission confirmed that there is water at the south pole of the Moon -- more than expected -- according to a NASA press conference yesterday. The results are published in the journal Science today.
The Centaur upper stage of the rocket that launched LCROSS and its companion spacecraft, the Lunar Reconnnaissance Orbiter, was targeted to impact a crater on the south pole of the Moon last year. LCROSS was able to observe the impact for a few minutes before it, too, impacted the Moon. Michael Wargo, chief lunar scientist for NASA's Exploration Systems Mission Directorate, characterized the material that the Centaur impacted as "fluffy snow-covered dirt." He said the Moon's south pole has some of the coldest temperatures in the solar system and can "preserve water ice in a vacuum for billions of years."
Wargo reported that they definitely saw water ice in the ejecta plume created by the Centaur impact, and it was 50 percent more than their initial estimates.
Presentation materials from the briefing are available on the LCROSS website, and an audio recording is available for the next 14 days by calling 1-888-566-0674. The New York Times has a nice summary.
NASA will celebrate the 10th anniversary of astronauts living aboard the International Space Station (ISS) next week. The anniversary itself is not until November 2, but on October 27 NASA will hold panel discussions at three NASA Centers -- Johnson Space Center, Kennedy Space Center and Marshall Space Flight Center -- as well as at NASA Headquarters. The participants and schedule were announced in a press release today.
To search for life elsewhere in the solar system and the universe beyond, one must first define "life." That was the message of a day-long celebration of 50 years of NASA research in exobiology and astrobiology on Thursday.
Molecular biologist Steve Benner explained to the audience that one can develop a "laundry list" of criteria that must be met for something to be described as life, but any such list necessarily rests on the biases of the person creating it -- a carbon-based life form that needs water to survive. What about life forms that might be based on other elements, like silicon? Benner was a member of a National Research Council study committee that published a report entitled Limits of Organic Life in Planetary Systems, dubbed the "Weird Life" report, which ruminated scientifically on other types of life forms that might exist.
Such questions are not only for Star Trek fans, but for researchers who are actively engaged in searching for life on other planets and their moons in our solar system and beyond. In this case "life" is just that, life, not necessarily intelligent life, which is the focus of the Search for Extraterrestrial Intelligence (SETI), a more controversial undertaking. As recounted by former NASA Administrator Dan Goldin in a rare talk about the space program since he left NASA in 2001, NASA has not directly supported SETI since 1993 when the Senate led the effort to cancel NASA's involvement in the program. Since then, SETI has relied on private sponsorship.
NASA, however, is fully engaged in the search for life in earlier stages. Since the life forms we know do require water for survival, "follow the water" became the theme for NASA's planetary exploration program while Goldin was Administrator. Although Benner and others want a more expansive view of what life might be, the reality is that one can only search for what one knows.
James Lovelock of Oxford University, founder of the Gaia hypothesis, reminisced about joining NASA in the early 1960s and being given the task of designing a method to determine if there is life on Mars in four days, which he did -- by studying the atmosphere. A decade later he published a book outlining a hypothesis he called Gaia, after the Greek goddess of Earth, that argues that life on Earth is part of a self-regulating system - essentially the planet and all the life on it function as a single organism. The somewhat controversial idea is that life on Earth developed and continues to exist not just because of luck, but because the physical, chemical and biological systems of Earth work together to regulate the planet to maintain that life. Some scientists refer to a "Goldilocks" zone around a star where temperatures are not too hot, not too cold, but just right for life to develop. Lovelock calls that "ridiculous," insisting that Earth is not within what scientists would consider the Goldilocks zone for our Sun, yet it is teeming with life because of the interaction of the atmosphere and everything else on the planet.
Lynn Margulis of the University of Massachusetts, one of the primary proponents of the Gaia hypothesis -- or theory, depending on one's viewpoint -- blamed neo-Darwinists for attacking it and explained that it takes time for people to accept a new way of thinking. Quoting Emily Dickinson, she told the audience that "The truth must dazzle gradually or every man be blind."
The seminar was information- and intellectually-rich. Topics included historical accounts of NASA's Viking program, the first designed specifically to find life on Mars, and of the ups and downs of astrobiology at NASA, which dipped when people misinterpreted Viking's findings as proof that there was no life anywhere on Mars, but resurged after the 1996 "Martian meteorite" discovery.
Cultural perspectives on the implications of finding life elsewhere -- or not finding it, which would be equally significant -- were discussed in a panel that included journalist Marc Kaufman of the Washington Post. He is writing a book on astrobiology and said that in his travels around the world doing research for it he found that people everywhere were fascinated by the search for life. A story he wrote for the Post on the discovery of a planet in the habitable zone of another star was the most read and emailed story on the Post's website for several days and shared on Facebook more than 7,500 times. Other members of that panel emphasized the need to consider religion and science together when communicating with the public since astrobiology is based on the theory of evolution. Connie Bertka of the Carnegie Institution pointed out that 42% of the U.S. population does not accept evolution and that number has been unchanged for 50 years.
But the question that kept returning throughout the day is "What is life?" Nobelist Baruch Bloomberg, who was the first director of NASA's Astrobiology Institute, argued that it is not that we are searching for life, we are testing the hypothesis that there is life elsewhere and searching for the data to prove the hypothesis. "How do you know if something's alive," he mused. "We have characteristics and if enough of them are satisfied then people say 'that's life.' It is hard to know how much data you need, but when it happens, you know it."
Former NASA Administrator Sean O'Keefe returned to work at EADS for the first time yesterday after being in an airplane crash in Alaska that took the lives of Senator Ted Stevens and four others. NASAWatch and Reuters both report the story.
Keith Cowing at NASAWatch adds a note from O'Keefe friend and former NASA General Counsel Paul Pastorek that Dateline NBC will have a one-hour segment devoted to the crash on Friday night at 9:00 pm, and O'Keefe will make appearances on NBC's Today show and CNBC that morning. O'Keefe's 19-year-old son, Kevin, also survived the crash and was interviewed for Dateline NBC along with his parents.
Reuters quotes O'Keefe as saying he is at 75% strength and still has "several hurdles to overcome," but "getting back to work will surely help speed that process along."
UPDATE: NASA's media teleconference on new results from LRO and LCROSS has been added for Thursday.

NASA's Kepler Mission and the SETI Institute invite anyone 18 or over to submit an essay in honor of Carl Sagan's birthday reflecting on the vision he inspired in his 1980 book, Cosmos, of Earth as the shore of the cosmic ocean.
Essays must be submitted by October 26, 2010 and the winner will be announced on Sagan's birthday, November 9. Dr. Sagan passed away in 1996. See the announcement for further instructions.
NASA's Kepler mission is searching for other habitable planets outside our solar system. The SETI Institute is a privately funded effort to search for intelligent life elsewhere in the universe.
The Space Foundation is making available a tracking tool for anyone who is following the mid-term elections and their impact on the space program. Available as either a PDF or Excel spreadsheet, the tool lists all the House and Senate members who are on the congressional committees that impact space program policy and funding or have constituent interests in space and whether they are running for reelection, retiring, or have been defeated in primaries. The list will be updated after the November 2 elections.
