Ensemble De Lancement Vega
ELV () is a launch complex at the Guiana Space Centre in French Guiana supporting launches of the Vega and Vega C rockets. It was first built in November 1971 and was previously used to support launches of the Europa, Ariane 1 and Ariane 3 rockets. History Europa (BEC) ELA-1, at the time designated BEC () was constructed as an equatorial launch site for the Europa-II rocket which was being built as part of the ELDO programme. The first launch occurred on 5 November 1971. This was the only flight of the Europa-II, which ended in failure due to a guidance problem. The launch site was mothballed, and later demolished. Ariane (ELA) When the Ariane 1 programme was started, to replace the failed ELDO programme, a new launch site was built on the site of the former BEC, re-designated as ELA (). The first Ariane 1 launch occurred on 24 December 1979. ELA was also used by Ariane 2 and Ariane 3 rockets, which first flew on 31 May 1986 and 4 August 1984 respectively. ELA was redesi ...

Viking (satellite)
Viking was Sweden's first satellite. It was launched on an Ariane 1 rocket as a piggyback payload together with the France, French satellite SPOT (satellites), SPOT 1, on February 22, 1986. Operations ended on May 12, 1987. Viking was used to explore plasma processes in the magnetosphere and the ionosphere. Spacecraft Space was limited underneath the SPOT 1 satellite, and Viking had to be quite sturdy in order to withstand the stress of launch. The basic shape of the Swedish satellite was a flat octagonal disc, 0.5 metres thick and 1.9 metres across. The mechanical interface of the Payload (air and space craft), payload adapter from the Ariane rocket was duplicated on top of Viking. This enabled it to be added to the launch with a minimum of redesign of the SPOT satellite. The satellite was developed by SAAB Space with Boeing Aerospace as a major subcontractor. The launch sequence was designed to enable Viking to separate and fire its own Star (rocket stage), Star 26C apogee k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Giotto (spacecraft)
''Giotto'' was a European robotic spacecraft mission from the European Space Agency. The spacecraft flew by and studied Halley's Comet and in doing so became the first spacecraft to make close up observations of a comet. On 13 March 1986, the spacecraft succeeded in approaching Halley's nucleus at a distance of 596 kilometers. It was named after the Early Italian Renaissance painter Giotto di Bondone. He had observed Halley's Comet in 1301 and was inspired to depict it as the star of Bethlehem in his painting ''Adoration of the Magi'' in the Scrovegni Chapel. Mission Development Members of the ESA’s Solar System Working Group started investigating a mission to Halley’s comet in 1977 before rejecting it in August 1978 in favour of a lunar orbiter. Shortly afterwards this was reversed by the Science Advisory Committee and the ESA started to study a joint mission with NASA. This mission was to be the International Comet Mission consisting of a carrier NASA probe and smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
