Plus de photos depuis hier; le rover est en panne....
PASADENA, Calif. - The ground team for NASA's Mars rover Curiosity has
switched the rover to a redundant onboard computer in response to a
memory issue on the computer that had been active.
The intentional swap at about 2:30 a.m. PST today (Thursday, Feb. 28)
put the rover, as anticipated, into a minimal-activity precautionary
status called "safe mode." The team is shifting the rover from safe mode
to operational status over the next few days and is troubleshooting the
condition that affected operations yesterday. The condition is related
to a glitch in flash memory linked to the other, now-inactive, computer.
"We switched computers to get to a standard state from which to begin
restoring routine operations," said Richard Cook of NASA's Jet
Propulsion Laboratory, project manager for the Mars Science Laboratory
Project, which built and operates Curiosity.
Like many spacecraft, Curiosity carries a pair of redundant main
computers in order to have a backup available if one fails. Each of the
computers, A-side and B-side, also has other redundant subsystems linked
to just that computer. Curiosity is now operating on its B-side, as it
did during part of the flight from Earth to Mars. It operated on its
A-side from before the August 2012 landing through Wednesday.
Quelque part sur Mars, un robot nommé Curiosity, censé nous fournir des informations sur cette planète prend des centaines de photos tous les jours, et nous les transmet. Certaines de ces photos, publiées pas la NASA présentent des choses surprenantes, pas toujours explicables: jeux d'ombres et de lumières, objets réels ou pas, artefacts, interprétations de l'esprit...de quoi alimenter ces pages et se laisser aller a des rêves cosmiques ou comiques :)
