TDRS-M – Behind The Black – Robert Zimmerman

ULA’s Atlas 5 successfully launches NASA communications satellite

Capitalism in space: ULA this morning successfully launched NASA TDRS-M communications satellite, following a several week delay caused by an accident during satellite preparation that forced the replacement of the satellite’s antenna.

This was ULA’s fifth launch for 2017, which is behind the once-a-month pace they have maintained for the previous five years.

TDRS-M launch moved to August 20

NASA has decided to delay the launch of its TDRS-M satellite until August 20.

This simplifies their launch schedule, as it allows SpaceX to launch as planned on August 12 and thus not interfere with an August 17 Russian spacewalk that is releasing two satellites from ISS. It will also give them plenty of time to replace the antenna that was damaged during launch prep, in an incident which they still have not described in any detail.

The damage and repair of TDRS-M creates complicated scheduling problems

July 26, 2017 9:10 am Robert Zimmerman

Because of the launch delay caused by the accident that damaged the antenna of NASA’s TDRS-M communication satellite, requiring its replacement, the agency is now faced with a cascading series of scheduling problems.

They are now aiming for an August 10 launch of TDRS-M on a ULA Atlas 5. This will then force a delay in the August 12 launch of a Dragon capsule to ISS to August 14, which can’t be delayed past August 16 because of a scheduled Russian spacewalk on ISS that must happen on August 17 because it involves the release of two satellites. Making things even more complicated is Dragon’s cargo, which includes mice for a rodent experiment. If it doesn’t occur before August 16, the mice will then have to be replaced with fresh mice, causing further delays.

There is then even the chance that these scheduling problems might impact SpaceX’s scheduled August 28’s launch of the X-37B, as well as ULA’s scheduled August 31 launch of surveillance satellite.

One additional tidbit: This Dragon will be the last unused cargo capsule. All future SpaceX cargo missions will use previously flown capsules.

I should add that these scheduling issues illustrate starkly the growing need for more launch sites. There is money to be made here, fulfilling this need.

NASA and Boeing to replace damaged antenna on NASA satellite

July 20, 2017 8:49 pm Robert Zimmerman

Due to an accident during satellite launch preparations, NASA and Boeing are planning to replace a damaged antenna on NASA’s TDRS-M satellite, used by NASA mainly for communications between the ground and ISS.

The update at the link however says nothing whether the satellite will still launch on August 3, as presently scheduled. Nor have they released any information about the accident itself.
