  • CFESat - . Payload: Heavily modified Surrey MicroSat-100. Mass: 159 kg (350 lb). Nation: USA. Agency: Los Alamos. Manufacturer: Surrey. Class: Technology. Type: Navigation technology satellite. Spacecraft: MicroSat-100. USAF Sat Cat: 30777 . COSPAR: 2007-006F. Apogee: 563 km (349 mi). Perigee: 558 km (346 mi). Inclination: 35.4000 deg. Period: 95.90 min. The Cibola Flight Experiment satellites carried eight new technologies for space flight validation, including a new power supply, inflatable antennas, deployable booms, a new type of launch-vehicle separation system, and a high-density pack of AA lithium-ion batteries. Cibola's on-board field programmable gate array supercomputer processed data onboard, then beamed only the results rather than the raw data to the ground. The Cibola also had a science mission: the study of lightning, ionospheric disturbances, and other sources of radio frequency (RF) atmospheric noise.

  • Tachys - . Mass: 152 kg (335 lb). Nation: Germany. Agency: Makeyev. Manufacturer: Surrey. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: SSTL-150. USAF Sat Cat: 33312 . COSPAR: 2008-040A. Apogee: 632 km (392 mi). Perigee: 606 km (376 mi). Inclination: 98.0000 deg. Period: 97.10 min. RapidEye AG of Brandenberg paid for launch of a constellation of five environmental monitoring satellites in a single launch, each with a mass of 152 kg including 12 kg of propellant. The satellites had an optical resolution of 6 meters, and were designed to provide on-demand images for agricultural storm damage assessment and support of emergency services.
