 Revised: Feb 13, 2015              Venus Express Spacecraft               -248

 NOTE: Full contact with the spacecraft was lost on Nov 28, 2014; telemetry 
  and command links were partly re-established, but were unstable and only 
  limited information could be retrieved.

  It is thought the spacecraft exhausted its remaining propellant about halfway
  through a set of maneuvers Nov 23-28 intended to raise periapse and prolong
  the mission into 2015. The nominal mission length of 500 days had already
  been extended to eight years.

  No further trajectory updates are expected.

   Nominal mission: 500 days in 24-hour elliptical, quasi-polar Venus orbit

 Venus Express is ESA's first mission to Venus. 

 Venus Express was designed to be the first space probe to perform a global 
  investigation of the Venusian atmosphere and plasma environment.
