A Kosmos 3M failed in its attempt
to launch QuickBird 1 from Plesetsk Cosmodrome at 2300 UTC (3 p.m.
PST) November 20. Signals from the satellite were not picked up as
planned by ground stations. The US$60 million satellite was to be
owned and operated by EarthWatch Inc., Longmont, Colorado. The
launch was reportedly insured for US$230 million.
During the final stage of the
satellite's entry into orbit, it was outside the field of Russian
tracking stations. However, after entering the tracking stations'
reach, the QuickBird satellite did not make contact with Earth.
U.S. tracking data indicated the satellite's
initial orbit was 81 km x 614 km (44 nmi x 332 nmi) at 65.8
degrees, and now lists the orbit as "decayed".
Rosaviakosmos (Russian Aerospace Agency - RAKA) reported that
preliminary analysis indicates the second stage of the Kosmos 3M
may have shut down too early. Cosmodrome experts have identified
three possible scenarios: the thrust value of the second stage
engines had been improperly oriented and caused a malfunction in
the control system, the engines did not develop sufficient thrust
or the nose fairing cone covering the satellite did not
separate. A commission headed by the
cosmodrome's commander will investigate the situation.
EarthWatch
lost its first satellite EarlyBird 1 in 1997, due to a problem
with the satellite’s power system. EarthWatch has been working
with Ball Aerospace, Kodak, and Fokker Space in the development of
the QuickBird family of satellites. QuickBird 1 was to be followed
in the middle of 2001 by the launch of QuickBird 2.
QuickBird 1 was planned for orbit a
circular 590 km (319 nmi) orbit, inclined at 66 degrees. This
inclination was to permit unique imaging times. QuickBird 1 was to
collect both one-meter resolution digital black-and-white imagery
and four-meter resolution digital color images. These high
resolution images were to be taken by the QuickBird instrument, a
high resolution camera, during orbital day-time.
Digital images taken from orbit were expected to rival aerial
photography in terms of both cost and possible economic and
scientific applications. The 950 kg (2094 lbm) spacecraft was
manufactured by Ball Aerospace and Technologies, Corp., Boulder,
Colorado and was based on the Ball Commercial Platform 2000 (BCP
2000) satellite bus.
EarthWatch has been developing a
network of satellites to image different regions of the Earth for
a variety of commercial applications, including environmental
monitoring, land management, mapping, agriscience studies, and
disaster monitoring.
