1. Delhi skies were just clear enough last Sunday to let sky-watchers have a ringside view of
a close encounter in space: a half-a-mile-wide asteroid buzzing the earth at a distance a
little farther than the moon. It was a rare opportunity to watch a close-up of one of these
visitors from the asteroid belt between the orbits of Mars and Jupiter who often drop in
without notice and cause the world's pulse to quicken.
2. A two-mile wide tumbling rock from space suddenly became the cynosure of all telescopes
last month as astronomers proclaimed it the most earth-threatening object' ever detected
Preliminary calculations even suggested it might hit the earth in 2019. That it proved to be
a false alarm is another matter. What's important is that such celestial brushes may form
part of a countdown to Armageddon.
3. For every asteroid spotted, several whiz by unnoticed, with some actually passing closer
to us than the moon. The number of these Near Earth Objects, or NEOs, far exceeds the
known list-a catalogue that needs to be completed before it's too late
4. Space, agencies have projects to push potential earth-grazers off course. But there's yet
to be a comprehensive global space watch program. Most NEOs slip through unnoticed
because of limitations to telescope time, technology and funding. So, it's important for
governments not to grudge asteroid hunters the resources they badly need to keep a close
watch.
5. A global asteroid monitoring system of sorts already exists in the form of an assorted group
of government and private agencies, along with amateur and professional asteroid
researchers. But it has no mechanism to assess the risk factors of NEOs or to determine
what, and how much, information should be passed on to the public. As a result, the
discoveries of more NEOs do not necessarily lead to a corresponding increase in public
awareness of the threat they pose. Newspapers, television and movies aren't of much help
