2005 CloudSat News
29 December 2005
- The Boeing labor union strike enters its ninth week, and all
spacecraft launch processing remains on hold.
29 November 2005
- Due to the Boeing labor strike and other issues, the earliest possible
launch date is in February 2006. The spacecraft are being prepared
for an extended period in the Astrotech payload processing facilities
on North Vandenberg.
- Starting on 19 December, the Western Range begins a planned two-month
maintenance, upgrade and refurbishment period. Work will be performed
on Range Safety tracking facilities, computers and launch support
- While progress has been made on the problems encountered during
testing of the Flight Termination System batteries, Boeing has not
formally determined and documented a root cause for engineering review.
Approximately 15 days are necessary to prepare for launch once all
issues are resolved.
23 November 2005
- The CloudSat Project was notified that because of insufficient
on the resolution of the Boeing labor problems, among other factors, the
CloudSat and CALIPSO satellites will not be able to launch in December
2005. The two missions will have to wait until after the re-opening of
the Vandenberg Air Force Base (VAFB) in February 2006 before their first
launch attempt. We are implementing their planned contingency activities
to place the two satellites in standby for the reminder of 2005, and
completing plans to define the appropriate start-up time and startup
activities in order to support a launch as early as mid-February 2006.
17 November 2005
- Another spacecraft battery reconditioning activity was successfully
10 November 2005
- Repairs on the JPL Airborne Cloud Radar are completed. The system was
installed into the Twin Otter aircraft and test flights begin this
Friday. Following the test flights, the aircraft will be shipped to
Darwin, Australia, to participate in the TWP-ICE field experiment for
CloudSat validation from Jan-Feb 2006.
- Spacecraft battery reconditioning started on 8 November 2005.
- All other spacecraft launch processing activities are on indefinite
hold due to the International Association of Machinist (IAM) strike
against Boeing. The FTS battery situation is also still unresolved.
3 November 2005
- Due to the Boeing labor union strike, CloudSat continues to stand
- CloudSat and CALIPSO are installed within the Dual Payload Attach
Fitting at the Astrotech payload processing facilities. When Boeing
labor contract issues are resolved, the payload combination will be
placed in an environmentally-controlled canister and installed on the
payload transporter for the trip to the launch pad.
- Delta II preparations at Launch Complex 2 have gone according to
schedule. Work is on hold until the payloads arrive at the pad for
installation on top of the second stage.
31 October 2005
- CALIPSO and CloudSat are installed within the Dual Payload Attach
Fitting. They continue to undergo spacecraft battery charging. The
processing team is maintaining the spacecraft safely inside the payload
facility at Vandenberg. NASA, Boeing and the Air Force are addressing
the problem encountered while testing batteries used for the flight
termination system of the Delta II.
27 October 2005
- Due to the imminent threat of labor union strikes, NASA decided to
delay CloudSat-CALIPSO spacecraft canning operations which were to take
place on Monday, 24 October 2005. As a result of this delay, the launch
is on a day-for-day slip.
- Spacecraft battery reconditioning was completed on schedule.
20 October 2005
- The CloudSat Team is continuing to work launch activities to a launch date of no earlier than 7 November.

Kirtland AFB last week. The detachment commander concluded the staff
was ready to support operations and gave his approval to proceed with
activities supporting launch.
- The CloudSat dress rehearsal was successfully completed at the RSC
- CloudSat spacecraft battery reconditioning began on 19 October and
will conclude on Saturday at the Astrotech payload processing facility.
19 October 2005
- NASA, Boeing, and the U.S. Air Force are working on the problem encountered
while testing batteries used for the flight termination system of the
Delta II. CALIPSO and CloudSat are installed within the Dual Payload Attach
Fitting. CloudSat will continue to undergo final battery charging through
Saturday. On Sunday, the combination will be placed in an
environmentally-controlled canister and installed on the payload transporter
in preparation for the trip to the launch pad. Delta II preparations
at Space Launch Complex 2 continue, as the launch vehicle awaits arrival
of the payloads for installation on the second stage on 24 October.
13 October 2005
- The launch was postponed pending resolution of a problem encountered while testing
launch-vehicle flight-termination system batteries. CALIPSO and CloudSat are
installed within the Dual Payload Attach Fitting and are undergoing final battery
charging in preparation for transport to the launch pad. Except for the battery
problem, Delta II preparations at NASA's Space Launch Complex 2 continue to go well.
- A launch countdown rehearsal was conducted at Vandenberg Air Force Base with
participation from mission operations support complex personnel at Kirtland
Air Force Base.
- Spacecraft battery reconditioning was completed on schedule.
6 October 2005
- The RSC (Research, Development, Test & Evaluation Support Complex) completed a series of
proficiency supports for CloudSat at each of the 15 AFSCN (Air Force Satellite Control
Network) antenna stations. This activity involves bringing up the CloudSat configuration
at the station, sending commands, and playing recorded telemetry from the antennas back
to the RSC. The database configurations were verified at all stations and
the AFSCN is ready to support launch.
- The final spacecraft battery reconditioning was started at Vandenberg Air Force Base.
22 September 2005
- A successful Launch & Early Orbit mission phase Ascent Simulation was held last week.
An independent committee from within ESMO provided simulated orbit data to the participants
per the simulation timeline. Operations teams from CloudSat, CALIPSO, ESMO CCS, and Aqua/Aura
Flight Operations were all participants. They tested the operations procedures for addressing
off-nominal injection errors, daily product deliveries, and coordination/communication during
the L&EO mission phase. No critical issues were found.

The CloudSat Science Team held a special meeting in Santa Fe last week to plan "first light" research for the first six months after launch and to review the plans for validation. A number of "first-light" activities were identified, including improvements to satellite cloud and rain products (e.g. MODIS, TRMM), comparisons with numerical weather prediction results (e.g. cloud fields and rain/no rain identification), and a focused study of arctic dehydration-greenhouse feedback. A number of new validation activities were presented, including a Japan-funded shipborne radar-lidar cruise from San Diego to Japan (Oct 2005- Feb 2006), flights of the University of Wyoming King Air cloud radar, aerosonde flights out of Wallops Flight Facility (Virginia) and Australia, and possible ground and aircraft observations in China. These activities are in addition to the already planned activities in Canada and Europe, and the Darwin, Australia experiment.

Prof. Graeme Stephens, CloudSat Principal Investigator, was named a Colorado State University Distinguished Professor. This is the highest academic recognition awarded by the University, bestowed upon no more than 12 CSU professors at any one time on the basis of outstanding scholarship and achievement. Professors receiving this title hold the distinction for the duration of their association with the University.
Ground support equipment was shipped from the BATC (Ball Aerospace & Technologies Corporation) campus in Boulder, CO and arrived at VAFB (Vandenberg Air Force Base), located on California's central coast, on 26 April 2005.
