SAMPEX

 1992-038A


The first SMEX was SAMPEX, the Solar and Anomalous Magnetospheric Particles Explorer. It carried a set of experiments from a team lead by the University of Maryland, and was built in-house at NASA-GSFC.

The 158 kg satellite was a box + 2 panels 0.86m in diameter and 1.5m long. It studied trapped radiation in the magnetosphere, solar flare composition, cosmic rays, and precipitating electrons.

LEICA is a high resolution mass spectrometer for low energy particles in an approximate range of 0.2-10 MeV/nucleon. MAST measures isotopic composition with a mass resolution of 0.3 amu in the 15-300 MeV/nucleon range; PET measures H and alpha in the same range and electrons in 0.4-30 MeV. HILT detects particles in the 10-200 MeV/nucleon range.

Launch was at 1419 on 1992 Jul 3 by Scout S215C from Space Launch Complex 5 at Vandenberg AFB into a 550 x 657 km x 82 deg orbit. SAMPEX was still operating in 1994. POCC was at GSFC with a Science Ops Center at Maryland. In 2010, SAMPEX was being operated by the Bowie State control center in Maryland.

Radarsat 1

 1995-059A




The CSA's Radarsat was built by Spar Aerospace. The 4.2m long, 2.8m wide spacecraft bus, built by Ball and based on the RME satellite, carried a large solar array and a 15 x 1.5m C-band synthetic aperture radar. It had a mass of 2750 kg. The radar has a 500 km swath width and can be steered electronically, with a fine (8-m resolution) 50 x 50 km area mode and a scan (100 m resolution) 500 x 500 km mode. It is intended to image the Arctic region and Canada, and will also improve maps of the Antarctic. 15 percent of the observing time is allocated to the US in return for the launch. Radarsat is to be operated by the Canadian Space Agency from the Radarsat Control Center at St Hubert, Quebec. Radarsat was launched into a 6am/6pm sun-synchronous orbit for continuous solar array illumination.

In Sep 1997 the satellite was flipped in orientation (yaw) to begin the Antarctic-1 mapping mission, imaging to the left of the satellite track.

The MDA company operates Radarsat. The Dept. Foreign Affairs and the military DND does tasking for surveillance to MDA; commercial tasking is done directly by MDA, while civil tasking is sent to MDA by CSA.

Payload:

  • C-band 1.5 x 15m SAR radar, 5.3 GHz

GSAT-2

 2003-018A


GSAT-2 launch mass was 1823 kg, 840 kg dry. Prop was MMH/MON-3. Size 2.4 x 1.6 x 1.5m with 9.6m span. Launch 2003 May by GSLV-D2 into GTO; LAM to GEO at 48E.

D2 had 10t of extra prop in stage 1, and improved strapon and stage 2 engines. Mass 414t at launch. The S139 first stage has four L40H strapons. GS2 is 11.6l 2.8d with 39.3t prop of UH25/N2O4 and 804 kN thrust. GS3 is cryo, 8.7l 2.9dia. The payload adapter was also made lighter, for a total gain of 485 kg; the lower-than-design Isp of the 12KRB represented a loss of 200 kg.

Launch from SDSC-SHAR (Satish Dhawan Space Center). Azimuth 104 deg.

The satellite carried SOXS, a solar X-ray spectrometer.

IceSat

 2003-002A


EOS Laser ALT-1, or ICESAT (Ice, Cloud and Land Elevation Satellite), launched to 705 x 705 x 94. ICESAT is built by Ball Aerospace/Boulder under an IDIQ contract with the BCP-2000 (Ball Commercial Platform) bus. ICESAT will study the Greenland and Antarctice ice sheets.

The 300 kg ICESAT is mounted on the RH-DPAF (Reduced Height Dual Payload Attach Fitting) containing CHIPSAT. RH-DPAF consists of an upper cone/cylinder and a lower cone.

The GLAS lidar instrument is a 1-m telescope with a ND-YAG 0.5 and 1 micron laser. ICESAT is 3.1m tall, 1.9m in dia, with two 2.1 x 2.3m solar panels for an approx 6.5m span.

The first of ICESAT's 3 lasers failed after only 36 days due to a solder contamination problem. A second laser was activated in Sep 2003.

Thor 3

 1998-035A


Thor III is an HS376HP to be colocated at the Nordic Hot Bird position of 1W with other Thor satellites belonging to Telenor AS/Oslo. Launch was Jun 1998 by Delta 7925 with a 9.5 foot fairing. It will broadcast DTH to Nordic countries, and central and eastern Europe. The satellite has 1400W generated by GaAs solar cells. Hughes delivered the satellite on orbit to Telenor.

Launch mass was 1451 kg. Size is 2.16m dia, 3.32m high stowed, 7.76m high deployed. The mission used a 'Thor 2A DTO' boost trajectory, with three Delta stage 2 burns to a high perigee geostationary transfer orbit.

STS-104 (Atlantis)

 2001-028A


Transfer of Atlantis to the VAB was delayed while the tiles were dried out; they had been soaked while at Edwards and moisture was still trapped almost three months later. Problems on orbit with the SSRMS delayed the launch further.

Launch mass is 117127 kg (press kit). OMS 2 mass is 116074 kg. Pre docking mass is 111066 kg. Docked mass with ISS is 231515 kg. Post undocking mass is 100606 kg, post sep 100572 kg. OV launch mass 117127 kg. Airlock 6063 kg. Landing mass 94007 kg.

The astronauts removed thermal covers from Quest. They returned to the airlock briefly while it was unberthed, but then emerged again to go to Unity to monitor its installation.
