Orbit Debris Space Threat to FORMOSAT-3 / COSMIC
•  More than 18,000 tracked Objects (> 10 cm) travelling around the
earth now, only 900 of them are active satellites
•  2007 January, the China FY-1C polar orbit satellite of
865 kilometres, with a mass of 750 kg was destroyed
deliberately.
–  It generate more debris than any other breakup and cause
total orbit debris number increased by 20%
•  2008 February collision of the Iridium 33 and Cosmos 2251
satellites
–  debris are concentrated near 800 km altitude where a large
number of spacecraft perform communications and Earth
observation missions. (FS3 are exact 800 km altitude)
–  1500 Large (>10 cm) Debris has been identified by US Space
Surveillance Network. Only half of them has chances to fall
back to Earth in 5 years.

•  Since Sep
2009，There are 6
warning alerts
issued by JSpOC
to NSPO SOCC.
•  Once higher
probability is
identified, it is
possibly to
perform orbit
transfer to avoid
the Debris threat.

Closing Remarks
 
Global warning has
become an international
attention
 
RO technique has shown a   NSPO has exhibited the first
successful operational RO
positive impact to the
constellation and ready for
weather forecast system
  Taiwan is willing to continue to
contribute to the RO weather
monitoring system to raise the
awareness of global warming
with reliable accurate weather
data
FORMOSAT-3/COSMIC FollowOn
 
NSPO is willing to continue   It is anticipated that the
Follow-on mission to be
the space mission for the
executed by the joint efforts of
remarkable constellation
NSPO and NOAA will continue
RO weather system
beyond 2014.
