Beagle 2 Science
Unique Objectives (in 2003):
Detection of extinct and/or extant life (detection of organics*)
 Analysis of subsurface material and regime
 First attempt at in-situ radiometric dating of rocks on another planet*
*Recently achieved by NASA’s Curiosity Mission

Beagle 2 Mission
Beagle 2 Mission Details:
Landing Site Isidis Planitia 11.6°N 269.5°W (90.5°E)
 Flat Ancient Impact Basin just North of Equator
 Launch 2nd June 2003
 Ejected from Mars Express 19th December 2003 08:31
 Expected Entry Time into Mars Atmosphere: 25th December 2003
02:51:22

Results:
No communication from Lander
 Presumed lost due to EDL or Lander Systems
Failure
 No data of EDL available as no EDL radio system
as no spacecraft available to receive signals
 Searched for using blind commanding and via
NASA imaging data
 ESA Inquiry
 Beagle 2 Internal Investigation
