05:35 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. Launch Pad: SLC17B. LV Family: Thor. Launch Vehicle: Delta 7920H.
  • SIRTF - . Mass: 923 kg (2,034 lb). Nation: USA. Agency: NASA. Class: Astronomy. Type: Infrared astronomy satellite. Spacecraft: SIRTF. USAF Sat Cat: 27871 . COSPAR: 2003-038A.

    Originally to have launched January 9, 2003. Delayed six times. The Space Infrared Telescope Facility (SIRTF) was the last of NASA's 'Great Observatories'. It had a 0.85-meter infrared telescope, with a liquid-helium cooled focal plane carrying the three main instruments. SIRTF was launched by the second Delta II Heavy. The second stage entered a 166 x 167 km x 31.5 deg Earth parking orbit, and after about 33 minutes of coast, passing south of Madagascar, restarted at 0613 UTC to enter a hyperbolic orbit with a perigee of 170 km, an eccentricity of 1.0061, and a velocity of 11.05 km/s. This placed it in a solar orbit of 0.996 x 1.019 AU x 1.14 deg with a year about 4 days longer than Earth's.

16:05 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. Launch Pad: SLC17B. LV Family: Thor. Launch Vehicle: Delta 7920H.
  • Fermi Gamma Ray Space Telescope - . Payload: SA-200HP. Mass: 500 kg (1,100 lb). Nation: USA. Agency: Martin. Class: Astronomy. Type: Gamma ray astronomy satellite. Spacecraft: SA-200. USAF Sat Cat: 33053 . COSPAR: 2008-029A. Apogee: 562 km (349 mi). Perigee: 542 km (336 mi). Inclination: 25.60 deg. Period: 95.70 min. Gamma-ray Large Area Space Telescope; renamed Fermi GST after launch..

2011 September 10

13:08 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. Launch Pad: SLC17B. LV Family: Thor. Launch Vehicle: Delta 7920H.
  • Grail A Ebb - . Mass: 202 kg (445 lb). Nation: USA. Class: Moon. Type: Lunar probe. Spacecraft: LM-300. Decay Date: 2012-12-17 . USAF Sat Cat: 37801 . COSPAR: 2011-046A.

    NASA dual-spacecraft lunar gravity mapping mission. Grail A was deployed from the Delta upper stage at 14:28 GMT and Grail B at 14:37 GMT. The spacecraft reached the Sun-Earth L1 point 1.5 million km from Earth and then fell back towards the Moon. Lunar orbit insertion was at 01:00 GMt on 1 January 2012 for Grail A, and at 02:00 GMT on 2 January for Grail B. After completing their mission, the satellites were intentionally crashed onto the lunar surface at 75.62 deg N / 26.63 deg W on 17 December 2012 at 22:29 GMT.

  • Grail B Flow - . Mass: 202 kg (445 lb). Nation: USA. Class: Moon. Type: Lunar probe. Spacecraft: LM-300. Decay Date: 2012-12-17 . USAF Sat Cat: 37802 . COSPAR: 2011-046B.
