SAGE

 1979-013A

---

Applications Explorer Mission B (AEM-B) was the Stratospheric Aerosol and Gas Experiment. The satellite carried a single experiment, the 4-channel SAGE radiometer which measured the intensity of the sun seen through the Earth's atmosphere on the horizon, studying aerosols and the ozone layer.

Launch was at 1618 on 1979 Feb 18 by Scout D-1 from Wallops Island. Orbit insertion was at 1629 and the fourth stage separated at 1633. SAGE was in a 96.7 min, 549 x 661 km x 54.9 deg orbit. It operated until 1981 Nov and on 1989 Apr 11 reentered from a 87.51 min, 146 x 157 km x 54.9 deg orbit.

Minisat 1

 1997-018A

---

Minisat-01 is a technology precursor to the Minisat-1 observation satellite and the Minisat-2 comsat. It carries technology and astronomy experiments. The EURD spectrographs will observe the interstellar medium. The LEGRI gamma ray experiment is a joint Spanish-British instrument, testing out advanced hard X-ray (10-100 keV) HgI2 detectors. A third experiment measures effects of microaccelerations on liquids.

The 209 kg satellite was built for INTA (Espana) by CASA. The Orbital Sciences Pegasus XL launch vehicle was attached to the L-1011 carrier plane at Torrej'on AFB, Madrid. The L-1011 then flew to Gando Air Base on the eastern end of the island of Gran Canaria. Gran Canaria is Spanish territory located just off the North African coast. On Apr 21, the L-1011 took off from Gando, and flew south to the drop point at 11.5 km over the ocean between Gran Canaria and Africa, at 27.0 N 15.33 W. Five seconds after drop, the XL ignited and soared westward to a record high inclination orbit in a ten minute flight. Minisat separated from the Pegasus third stage carrying the Celestis satellite. The inclination of 151.0 degrees was six degrees higher than the record set by OV1 satellites in the 1960s. Launch control and orbit control was from Maspolamas space center on the southern tip of Gran Canaria. Operational control is from INTA/Torrejon and the science operations center is at INTA's LAEFF lab at Villafranca del Castillo.

The satellite was 1.1 x 1.0 x 1.2m with four solar panels 1.5m in size, so approx 4.0 span.

Aurora 2

 1991-037A

---

The GE Satcom C-5 satellite was renamed Aurora 2 on reaching orbit; it is owned by GE Alascom and used for Alaskan domestic communications. The Series 3000 satellite had 24 C-band transponders.

1338 kg launch (Jane's); 644 kg BOL (Martin). About 180 kg hydrazine.

The transfer orbit perigee was 1440 km, occuring 30 minutes after launch. To reach such an altitude requires a steep climb; from the normal 185 km insertion orbit a 185 x 6700 km orbit is required to achieve the altitude in the required time and this seems unlikely. Alternatively a direct ascent orbit of -80 x 2625 km does the trick.

Synchronous Meteorological Satellite 1 was launched at 0931 on 1974 May 17 by Delta 2914 from Cape Canaveral. The Thor first stage shut down prematurely at 0935 after a LOX tank pressure loss; the Delta burned from 0935 to 0940 and reached a 155 x 213 km x 28 deg parking orbit with insufficent propellant to make its second 8s burn. After a 14 minute coast, the Star 37E third stage ignited at 0954. After it separated at 0956, SMS 1 was in a 182 x 33250 km x 24 deg transfer orbit, significantly lower in apogee than planned. The solid SVM-5 apogee motor fired at 0700 on May 19, and was followed by 9 daily thruster burns to raise the altitude. Finally on Jun 4 SMS 1 was near geostationary at 86 deg W. After a brief checkout it was stationed at 45W for GATE (the GARP Atlantic Tropical Experiment). SMS 1 was turned over to NOAA for operational use on 1974 Dec 10 despite problems with the S-band transmitter. By 1975 Oct it had been moved back to 75 W, which was to become the operational GOES East position. In early 1976 it was moved to 105W as a standby satellite, after being replaced by GOES 1. On 1979 Jan 26 it arrived at the GOES E position to replace GOES 2 in the First GARP Global Experiment (FGGE), but after SMS 1 had S-band transmitter problems in April GOES 2 took over again and SMS 1 moved to the side. SMS 1 spent 1980 at 131W backing up the GOES W position. On 1981 Jan 29 the orbit was raised by 500 km and SMS 1 was decommissioned a few days later.
