SUMMARY

Beagle 2 is currently on its final approach to Mars, relying solely on the alignment of Mars Express and its eject mechanism for navigation. The landing ellipse is now estimated to be 80km by 15km, significantly smaller than initially planned. Despite the successful trajectory, communication with Beagle 2 remains unestablished, raising concerns about its fate. Historical failures, such as the Mars Climate Orbiter crash due to unit conversion errors, highlight the challenges faced by space missions.

PREREQUISITES
  • Understanding of spacecraft navigation and propulsion systems
  • Familiarity with Mars Express mission parameters
  • Knowledge of historical Mars missions and their outcomes
  • Awareness of communication protocols in space exploration
NEXT STEPS
  • Research the Mars Express mission and its role in Beagle 2's navigation
  • Study the failure analysis of the Mars Climate Orbiter
  • Explore the communication technologies used in Mars missions
  • Investigate the design and objectives of the Beagle 2 lander
USEFUL FOR

Aerospace engineers, space mission planners, and enthusiasts interested in the challenges of interplanetary exploration and the history of Mars missions.

As part of Beagle 2 interest, I thought I'd post the mailshot I receive.

Latest:Beagle 2 is currently traveling the last miles of its journey to the Red Planet alone and without any propulsion systems of its own. Thanks to the careful alignment of Mars Express on 19th December and accuracy of the spin-up and eject mechanism it is now believed that Beagle 2 is heading for a landing ellipse measuring 80km by 15km, much smaller than originally envisaged.

Beagle 2 should have landed yet, but unfortunately is impossible to make contact with it

It's frustrating the amount of failures that are accumulating in the last missions to Mars, for example the loss of the Mars Climate Orbiter in 1999. It seems that is not a unique problem of NASA, now ESA wants to join the failure club.

Did they ever confirm for certain what happened to the Mars Climate Orbiter? Has it (or its wreckage) ever been found or detected?
 
Aw crap. Beagle still missing...

Japan lost its Nozomi mission to Mars back in early December too.

NASA still has the Spirit and Opportunity missions about to land on Mars (planned for Jan 3, 2004 and Jan 24, 2004 respectively). Keep your fingers crossed (or whatever the Martian equivalent is).

Keep your fingers crossed (or whatever the Martian equivalent is). I believe it's :Keep your tentacles crossed!

Actually the best communication window is set for the 7th of January04, that's when the mothership is at its optimum orbit for a direct overhead pass for the Beagle's 'intended landing zone'.

P.S The whole purpose of the Beagle is to trawl for 'Life', I wonder if there is genuine life there, and if so would this lifeform be 'communicating' with itself?..maybe the initial warning echo of :THE ALIENS ARE COMING!..THE ALIENS ARE COMING! have rung out across the Martian landscape..and the Beagle craft has been carted off to..maybe a 'coat-hanger No2?'at AREA 15?, and is currently being systematically back-engineered?[b(]

Certain? Yes; it crashed. Wreckage? Not seen yet, unlikely to be seen, even with Mars Express.

Cause of failure? One team used metric units, the other English; failure was guarranteed. Details:

well if it is in a crator, they said they might be able to get a signal with one of the orbiters by changing its path slightly.

I am surprised NASA didn't equip the MERs to pick up a beagle signal... I am sure they can probably contact each other

You'd think that at least one of the craft we've got (or will have) orbitting will have an omni-directional antenna. At least you'd hope that they would...
