One evening late last year, I left my Manhattan office and
started walking down Park Avenue. Glancing up at the sky, I noticed a bright
point of light passing overhead and slowly fading as it sunk towards the
southeast. I immediately realized, based on previous experience, that I was
looking at a space station—either Mir (it had been reported in the previous
day’s news that Russia had given up on Mir and would in a matter of months
plunge it into the Pacific) or the International Space Station (ISS). When I got
home, I checked the Heavens Above web page (
www.heavens-above.com
), which has information on
where and when to see bright satellites. Sure enough, I found I had been looking
at Mir.

The year 2001 is finally here, but
there are no spaceliners, let alone Pan Am to fly them. No lunar colonies. No
black monoliths, no psychedelic stargates. The only craft to have visited
Jupiter are spindly and unmanned, and as far as we know, their computers aren’t
psychotic. There are no giant wheels spinning in orbit to the tune of Strauss
waltzes. But there are space stations; for the next month, perhaps, there are
still two of them.

As urban observers, light pollution
can impose severe restrictions on what we are able to see. This can prove
particularly frustrating to newcomers to amateur astronomy, or those with
minimal equipment or without a decent observing site. However, the brightest
satellites, particularly the space stations and the Shuttle, can be easily seen
without optical aid, and can provide a moving and thought-provoking look into
the High Frontier, the extension of humanity’s questing spirit into Earth’s
orbit, and sometimes the feeling of history in the making; over a three-day span
in early February, I watched the Space Shuttle Atlantis from launch through
rendezvous and docking with the ISS. On Wednesday, February 7, from the top of
the Empire State Building, I saw the Shuttle (a probable sighting) just after
launch as it rocketed up the East Coast, just skirting the southeastern horizon
before its main engine burned out and it was plunged into darkness. (This was
thanks to Joe Rao’s predictions.) The following night, from my
neighborhood of Ridgewood, Queens, I watched the ISS pass nearly overhead, to be
followed a few minutes later by the Shuttle; both rivaled Jupiter when at their
brightest. Two nights later, I saw the linked Shuttle-ISS pass overhead, shortly
after the deployment of the Destiny science module. Binoculars, though, showed
them only as a single point of light.
The Heavens-Above web site, as well
as several others, gives information regarding satellite passes, including
expected brightness, passage times and trajectories, even maps showing the path
the satellite will take across the constellations.
The space stations
tend to be visible in cycles, with a couple of weeks of morning passes visible
from a given location, followed by a string of evening passes. If it has not yet
been crashed into the Pacific, Mir will be in the evening sky in early March;
this will likely be its last period of visibility. Particularly promising are
the passes of March 9 and 10, when it is high in the sky with a magnitude of
about –1.
