GOES-10

 1997-019A


GOES K was launched in Apr 1997 on the final Atlas I Centaur and renamed NOAA GOES 10. Mass was 2100 kg. GOES 10 was placed in on orbit storage as an operational spare. The plan was to spin-stabilize it while in storage. A solar panel drive failure in Jun 1997 threatened the mission, but operating it in reverse (and flipping the whole satellite) fixed the problem, at the cost of rewriting the ground analysis software.

HETE-2

 2000-061A


The HETE-2 gamma ray burst locator satellite was funded to replace the original HETE lost in a launch failure. It replaced the UV sensor with an extra soft X-ray imager, following the discovery by BeppoSAX of X-ray afterglows to gamma ray bursts. HETE-2 is built by MIT rather than AeroAstro, using left over HETE parts. The ground network is a series of small terminals across the world, which relay data back to MIT. MIT operates the satellite; management is GSFC.

HETE-2 was staged from KMR on Pegasus mission P-35. The Pegasus H (Hybrid) has standard stages 1 and 2, with XL's stage 3 and avionics. Takeoff from PKWA (Bucholz Army Airfield) RW 06/24, at 08 42.9N 167 43.6E. Drop point is 7.65N 167.7E; azimuth is 118.45 deg, altitude 11.9km.

Launch control was remotely from CCAFS Hangar AE.

Mass is 124 kg. Size is about 1.0h 0.5d 2.5 span. Resolution 10' to 10".

In Dec 2005 NASA stopped funding but MIT continued operating the satellite.
