It is common knowledge that leads time is often a critical aspect of Procurement of EEE parts for Space Applications. Some specific family types usually suffer from having long lead times (more than 1 year on some occasions), which makes them a major driver on any procurement. One of the most affected families are Space Qualified Panel C Mounted EMI filters.
During the Evaluation phase, components/technologies can be expensively characterized and margins determined. If the evaluation is successful we can then proceed with Qualification, on components produced strictly as defined in the final PID (Process Identification Document) and from a given lot (actually, the first production lot). Once qualified, the component is listed in the QPL (Qualified Part List).
LISA Pathfinder is paving the way for future missions by testing in flight the very concept of gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy.
The Meteosat program finds its origin in 1977 when the first prototype satellite was launched to explore the technologies needed to acquire meteorological data from Geostationary Orbit. Two more prototype satellites were launched in 1981 and 1988 before the first operational satellite, Meteosat-4, launched in 1989. As part of the Meteosat Operational Program, three satellites were launched followed by Meteosat-7 in 1997 as part of the Meteosat Transition Program that was implemented to bridge the gap between the first and second generation of Meteosat spacecraft by launching one improved first generation satellite.
The space probe Rosetta was built by the European Space Agency (ESA ) with the objective of reach and study Comet 67P/Churyumov-Gerasimenko. Was launched on March 2004 from Kourou. To place it on the required orbit to rendezvous with Comet 67P/ Churyumov-Gerasimenko it received four gravity assist manoeuvres: 3 from Earth (4 March 2005, 13 November 2007 and 13 November 2009) and 1 from Mars (25 February 2007).
The HTV vehicle is an unmanned spacecraft that in an autonomous way is able to supply food, replacement parts, test equipment and other items to the crew of the ISS. The “brain” of this vehicle – it is Avionic Module – was developed by Mitsubishi Electric. Currently, several launches of this ship are planned in addition to the 6 (HTV-1, HTV-2, HTV-3, HTV-4, HTV-5 and HTV-6) made to date.
