Bonjour à tous,
The problem of parachutes to land on the red planet the European rover Rosalind Franklin and its surface platform Kazachok built by Russia will most likely result in the postponement of the Exomars mission to the next (but farther) launch window, in about two years.
The European and Russian space agencies are to meet on 12 March to make a final decision on this subject.
Until then, it was expected that the launch would take place in July this year from the cosmodrome in Baikonur, Kazakhstan. But the problems found during parachute deployment tests will certainly not be solved in time.
An ESA spokesperson said:
"An operational review of the project took place between ESA and Roscosmos at the end of January. A preliminary assessment was sent on 3 February to the heads of space agencies, Jan Wörner of ESA and Dmitry Rogozin of Roscosmos."
"Programme leaders were asked to submit an updated plan and schedule covering all remaining activities necessary for the authorisation to launch. This plan will be reviewed by the two heads of agencies who will meet on 12 March to jointly agree on next steps."
With this deadline, we are waiting for a public announcement on a possible confirmation of a launch in July or, more probably, of a two-year postponement at the next window favorable for a launch towards March.
The modifications on the parachute system that have been undertaken since the discovery of the problems must be validated, with the help of the JPL, by a last test at high altitude which was initially planned during February. Unfortunately, a change in NASA’s schedule would have postponed this indispensable test in March.
In its space section, the BBC informs us of another complication concerning especially the rover Rosalind Franklin.
Thales Alenia Space reportedly discovered a defect in the hinges of the solar panels of the rover. The problem was found on the rover test model and on the flight model during the thermal and vacuum tests. The glue that was holding the hinges in place took off. Engineers are working to solve this problem. It is planned to replace the glue with bolts. The margins for the maximum payload are such that it’s not really going to be a problem.
In two weeks we should be fixed the fate of this launch in July 2020 ...
