  • missed the window of opportunity for its flight to Mars
  • the probe could still be used in another research mission
  • Phobos-Grunt mission scientist Alexander Zakharov said that if the spacecraft is fully operational, the best scientific mission for it would be to study a near-earth asteroid.

  • on the rover's deck
  • is a plaque inscribed with the signatures of President Barack Obama and Vice President Joe Biden, in addition to other administration and NASA leaders
  • continues a more than 40-year tradition of sending presidential plaques on planetary missions
  • ...13 more annotations...
  • Elsewhere on the rover is the autograph of the 14-year-old girl from Kansas who gave Curiosity its name
  • millions of digital signatures from members of the public who signed up through NASA
  • NASA's Mars program leaders round out the autographs on the plate
  • It's on the rover in the front left corner
  • it will be visible and that at some point will be photographed on Mars by Curiosity's camera-topped mast
  • "When we made the request to the White House for permission to launch, we took this along with us and said, 'Oh by the way, if you sign this we will stick it on the rover.'"
  • Clara Ma, who won NASA's naming contest with the suggestion of "Curiosity," signed the rover in 2009
  • As part of her prize, she was invited to the Jet Propulsion Laboratory in California, where in June 2009 she donned a "bunny suit" to step into a clean room and sign her name on the rover
  • Silicon chips attached to Curiosity's deck bear the digital signatures of people who submitted their names through NASA's website for going to Mars aboard the rover. Each chip is about the size of a dime
  • More than 1.24 million names were submitted online
  • etched into silicon using an electron-beam machine used for fabricating micro-devices at JPL
  • more than 20,000 visitors to locations of work on the rover at JPL and Kennedy Space Center wrote their names on pages, which were scanned and reproduced at microscopic scale on another chip
  • As Curiosity drives over the martian terrain, the groves in each wheel will form a string of 'dash' and 'dot' imprints — morse code that will spell out "J-P-L."

  • signal was received at a Russian station at the Baikonur cosmodrome in Kazakhstan on Thursday afternoon
  • expected that fragments of the probe would fall to Earth in January or February although the exact date would depend on external factors
  • One expert said that its surprise show of life had generated hope that the probe could be brought down back to Earth safely

  • Following the first successful contact on Tuesday, ESA's tracking station in Australia again established two-way communication with Russia's Phobos–Grunt spacecraft on 23 November
  • data received from the spacecraft have been sent to the Russian mission control centre for analysis
  • The first pass was successful in that the spacecraft's radio downlink was commanded to switch on and telemetry was received
  • ...3 more annotations...
  • The signals received from Phobos–Grunt were much stronger than those initially received on 22 November, in part due to having better knowledge of the spacecraft's orbital position
  • Telemetry typically includes information on the status and health of a spacecraft's systems

  • the head of Russia's space agency, said after launch the mission could be salvaged until early December
  • many experts said the launch period has already expired, meaning Phobos-Grunt would have to wait until 2013 for another shot at Mars
  • Tuesday's brief contact did not produce telemetry to gain insight into the situation on-board the spacecraft
  • ...2 more annotations...
  • Phobos-Grunt is likely functional and charging batteries through its solar panels
