Ariane 40 V44 - Ariane 40 V44 - COSPAR 1991-050 13,688 bytes. 108 x 439 pixels.

As Ariane 2/3 with stretched first (61%) and third stages, strengthened structure, new propulsion bay layout, new avionics, Spelda dual-payload carrier. The basic 40 version uses no strap-on motors (see Ariane 42L, 44L, 42P, 44P, 44LP for figures on varous combinations of solid and liquid propellant strap-on motors). A fully fueled Ariane core cannot lift off the ground without strap-on liquid or solid motors. When Ariane 4 is launched in this configuration, the propellant tanks of the first and second stages are not completely filled. Development was authorised in January 1982, with the objective of increasing payload by 90%. Total development cost 476 million 1986 ECU's.

  Experimental Interferometric Microsatellite built by Interferometrics Inc, of Chantilly, Virginia. The satellite was also equipped with amateur radio equipment, constructed by AMRAD, a non-profit organization of radio amateurs, to conduct digital satellite communications experiments. The Amrad-Oscar-27 payload was an 'FM Repeater', consisting of a crystal controlled FM receiver operation at 145.850 MHz and a crystal controlled FM transmitter operating at approximately 436.795 MHz. Output power of the transmitter was normally 0.5 watts. Because of the satellite's limited power budget the amateur transmitter was on for only part of the daylight portion of each orbit. As of September 1998, the satellite passed its five year design goal.

• Healthsat 2 Spacecraft: Microsat SSTL. Mass: 48 kg.

  Customer: SateLife. Store and forward communications satellite operating in the SatelLife 'HealthNet' LEO satellite communications network for remote regions. Still operational as of 2000.

  Healthsat - II joined UoSAT-3/HealthSat-I as the second microsatellite in the HealthNet global communications system of SatelLife, a U.S. not-for-profit organisation. HealthNet, which was licensed in eighteen countries in Africa and Latin America, was providing desperately needed low cost 'last mile' communication links between medical institutions and health programmes in the developing world.

  The HealthSat-II mission was completed, from concept to launch, within one year. SSTL were responsible for all the programmatic aspects of the mission including procuring the launch slot on the Ariane ASAP and arranging suitable insurance for the launch and early commissioning phase - all within a total contract price of �1M. Additional Details: Healthsat 2.

• ITAMsat Spacecraft: Oscar. Payload: Oscar 26. Mass: 50 kg.

  ITAMsat was built by AMSAT-ITALY. Its mission was to store and forward amateur radio messages.

• Kitsat-2 Spacecraft: Microsat SSTL. Payload: Oscar 25. Mass: 49 kg.

  KITSAT-OSCAR 25 was a South Korean experimental microsatellite based on the SSTL UoSAT bus built by the Korean Advanced Institute of Science and Technology (KAIST). KO-25 was operated from The Satellite Technology Research Center (SaTReC) in South Korea. KO-25's mission was to take CCD pictures, process numerical information, measure radiation, and receive and forward messages. The Infrared Sensor Experiment (IREX) was designed to acquire I/V characteristics of IR sensors. A passive cooling structure was devised for this experiment. KO-25 was eventually operated purely as a packet store-and-forward satellite.
