Okay, soyou?ve started the New Year with big aspirations. Maybe you?ve got sky-highambitions to change the world?perhaps even save it.
How aboutfending off mean, nasty, Earth-threatening objects lurking out there in thedark of deep space? There?s surely heaps of glory and macho mojo to win by taking on such scarycelestial beasts Bruce Willis-style as depicted in that striking movie Armageddon!
For thoseof you sleepless in Seattle and elsewhere about Earth-poundingprojectiles from afar, the esteemed National Academies is on the lookoutfor scientific and technically credible ideas.
The SpaceStudies Board ? in coordination with the Aeronautics and Space EngineeringBoard of the National Research Council ? has put in gear a two-part study onNear-Earth Objects, or NEOs for short.
Ablue-ribbon group of experts has been selected to address issues concerning thedetection, tracking, and characterizationof NEOs ? and approaches to mitigating identified hazards.
Thiscommittee has issued a Request for Information (RFI) to solicit ideasto survey, detect and characterize NEOs, as well as potentialmission concepts for deflection/mitigation of Earth-smacking objects.
Thosewishing to submit their schemes may draw upon the use of different facilities ? ground-or space-based ? and/or involve international cooperation in their proposedsolutions.
Over theyears, there?s been a roster of NEO-thwarting proposals, among them: Blastingthem with reflected solar energy, nuking them outright, gravity tractors,strapping little rocket motors onto the object, even pushing a NEO out of theway by collective mental channeling.?
To get moreon this RFI request, I launched my own information probe to the committee.
?Congressasked the National Academies to look at current efforts for detecting andmitigating the threat posed by objects whose orbits may take them close to Earth. Specifically,Congress wants suggestions as to what steps to take next,? responded IrwinShapiro of the Harvard Smithsonian Center for Astrophysics and chairman of theCommittee to Review Near-Earth Object Surveys and Hazard Mitigation Strategies.
Shapirosaid that the study will be comprehensive, but added: ?In addition to lookingat all current efforts and ideas, we want to learn about new approaches thatmight be valuable. Hence, we've issued a request to the scientific andtechnical communities for such suggestions."
In seeking proposals, suggestions sent in must be anchored in reality. That is,they need to be capable of being evaluated both from a technical and from acost perspective, since one of the committee?s tasks is to produce costestimates of the options.
?So nomagic, please, just well-thought out concepts and plans commensurate with thetime available for response to this request,? Shapiro said.
Underscoring thatview is Dwayne Day, the study director for the NEO assessment: ?No moviescripts, please. Wedon?t need Bruce Willis.?
So theinvite is out to write a program or mission concept for detecting,characterizing, or mitigating the hazards of NEOs.
The deadlinefor ideas is March 20, 2009.
However,for logistical reasons, the Committee asks that you first submit a Letter ofIntent by Jan. 30, 2009.
