ISS : the output of Thomas Pesquet in the space is a great success – Futura Sciences

For its first extra-vehicular, the fourth by a Frenchman from Jean-Loup Chrétien in 1988, Thomas has perfectly accomplished its mission with a duration of 5 hours and 58 minutes. With his team-mate Shane Kimbrough (theastronaut of Nasa, who is the commander current on the ISS), two astronauts in particular have replaced the lithium-ion in order to improve the supply of energy of the station. These batteries, which should last for ten years, are now connected to 2,500 m2 of solar panels that supply energy to the Station and take their relay when it is in the shadow of the Eart h. The orbital complex orbits around the Earth in 90 minutes, which involves alternating every 45 minutes day and night.

A task performed much faster than planned, so that the two astronauts were able to do the activities are complementary, including the replacement of a camera being faulty, installed on the robotic arm and various other components. They have also made shots of a number of parts of the Station for control purposes.

An output in space is a team effort

The two astronauts were under the constant surveillance of their colleagues remained aboard the orbital complex and different control centers of the Station spread on the Earth. Since Houston, Thomas Pesquet was monitored by the Italian Luca Parmitano, the astronaut who officiated as capcom to guide the two astronauts, and by his medical team of twenty people. medical point of view, dr Brigitte Godard, doctor Thomas Pesquet of the Cnes detached from the european astronaut centre in Cologne, are not reported to us, no bad surprise. the ” An astronaut in full form and knowing how to keep calm in spite of the beauty and the complexity of the environment “ she commented.

In France, it was monitored from the Cadmos, the Centre of the Cnes to Aid in the Development of Activities in Microgravity and Space Operations. In the framework of the mission, Proxima, this team is going to drive 21 of the 55 experiences that lead Thomas Pesquet to theEsa. Seven of them, including Matiss (test for anti-bacterial surfaces, ” smart “), have been developed and directly prepared by the Cadmus.

ISS : Thomas Pesquet will be the fourth Frenchman to go out in to the space

Hope he is not superstitious. For his first stay aboard the international space Station, ESA astronaut Thomas Pesquet has been cleared out in the space. A dream that materializes. This output extra-vehicular will be live on the 13th of January, from 13: 05 a.m., Paris time, on the sites Internet of the Cnes, ESA and Nasa.

After Jean-Loup Chrétien in 1988, Jean-Pierre Haigneré in 1999 and Philippe Perrin in 2002, Thomas Pesquet is poised to become the fourth Frenchman to make a trip in the space ! On the 13th of January, from 13: 05 a.m. Paris time, it will perform its first extra-vehicular (EVA) in the framework of an operation of the maintenance to install new batteries to the outside of the ISS.

The French will come out with the commander of the expedition 50, Shane Kimbrough. Given its experience, the astronaut of Nasa has been appointed a member of crew extra-vehicular number 1 (EV1). It will be a combination of red tape, while Thomas will be a combination without a scratch and will have the designation EV2.

in this output, they will complete the work commenced on January 6, during the previous EVA, when Shane Kimbrough and Peggy Whitson have particular installed three new adapter plates and hooked up the electrical connections for three of the six new batteries of lithium-ion batteries on the orbital complex.

More electricity for the Station, the night

These two outputs have the aim of bringing to the level of the power supply system of the international space Station by replacing a 12-battery nickel-hydrogen that lose their power through six new lithium-ion batteries is delivered to the Station by the cargo ship HTV-6 in December 2016.

These new batteries, which enables the storage of the energy stored during the day by the solar panels of the ISS, and to redistribute it during periods of the night, have a capacity equivalent to two batteries, nickel-hydrogen, currently used on the station to store the electrical energy produced by the solar panels.

Thomas Pesquet book his first impressions aboard the ISS Three days after his arrival aboard the international space Station, Thomas Pesquet has answered the questions of journalists during a press conference about twenty minutes streamed live by the Esa. The spationaut, also tenth French to go into space, is obviously very happy and at ease in weightlessness : “we adapted very quickly “. He came back on his first impressions aboard the ISS, the organization of days, his trip in the Soyuz capsule, etc
