Editor AIAA Bulletin A devastating asteroid or comet impact is unlikely to come in my lifetime or that of my children. My cerebrum knows this, but a little deeper down is my limbic Contributing Writers system, and it subscribes to Murphy’s Law: Whatever can go wrong will go wrong, Philip Butterworth-Hayes, Keith Button, and probably sooner than expected. Duane Hyalnd, Tom Jones, Natalia There’s a reason our brains developed a complex emotional center. Emotions Mironova, Marc Selinger, Brian Steiner, focus us. We should be doing more to protect ourselves from a collision with a Robert van der Linden, Mark Williamson, Frank H. Winter near-Earth object. It’s not a likely event, but the stakes are almost unimaginable. Not all of the preparations would mean spending gobs of taxpayer dollars. The White Jane Fitzgerald House and Congress could create an agency or assign one to lead and marshal Art Direction and Design international talents before a dangerous object pops up. We know we should do James F. Albaugh, President this, but it’s easy to procrastinate, and that’s what we’ve been doing for a decade Sandra H. Magnus, Publisher now. In 2005, a NASA task force recommended establishing a Planetary Defense Craig Byl, Manufacturing and Distribution Coordination Office. As it stands, the Pentagon is focused on earthly threats. Congress has directed STEERING COMMITTEE Steven E. Gorrell, Brigham Young University; NASA to find, track and describe dangerous NEOs. No one has the job of figuring David R. Riley, Boeing; Mary L. Snitch, out how to deflect dangerous objects or blow them up. For its observation mis- Lockheed Martin; Vigor Yang, Georgia sion, NASA relies on a loose, global network of ground telescopes and astronomers Institute of Technology; Annalisa Weigel, from other organizations. A better way would be to launch a telescope into space Fairmont Consulting Group; Susan X. Ying specifically to look for NEOs. For that, we’re counting on a private group, the B612 EDITORIAL BOARD Foundation, to raise the necessary funds to build and launch the Sentinel Space Ned Allen, Jean-Michel Contant, Telescope in 2017. Maybe the foundation will succeed, but in the meantime, our Eugene Covert, L.S. “Skip” Fletcher, view of space remains disturbingly incomplete. We’re trusting that someone will be Michael Francis, Cam Martin, looking in the right place when the big one comes. Murphy’s Law says we should Don Richardson, Douglas Yazell plan on the opposite kind of luck. History shows that objects are sometimes spotted ADVERTISING alarmingly late. Comet Hale-Bopp, for example, was discovered in 1995 and flew Joan Daly, 703-938-5907 through the solar system in 1996 and 1997.
