Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.

  • Demeter - . Mass: 125 kg (275 lb). Nation: France. Agency: CNES. Class: Earth. Type: Seismology satellite. Spacecraft: Demeter. USAF Sat Cat: 28368 . COSPAR: 2004-025C. Apogee: 723 km (449 mi). Perigee: 695 km (431 mi). Inclination: 98.3000 deg. Period: 99.00 min. Demeter studied disturbances of the ionosphere due to seismo electromagnetic effects and human activities (power lines, VLF transmitters, HF broadcasting stations). Study of natural electromagnetic emissions in the ULF/ELF/VLF range related to seismic or volcanic activity could be used to predict earthquatkes or eruptions in advance. Demeter tracked these emissions and other space plasma parameters (ion composition, electron density and temperature, energetic particles). The scientific payload consisted of three electric and three magnetic sensors (covering six components of the electromagnetic field from DC to 3.5 MHz); a Langmuir probe; an ion spectrometer; and an energetic particle analyzer. 8 Gbits of onboard memory recorded the data, which was returned to earth as 18 Mb/s high bit rate telemetry in the X band. The two-year mission was handled from a control center in Toulouse.
