2 Mars Missions Set For Arrival, Both Prepare for Orbital Maneuvers

As reported by the BBC, NASA's Maven Mars orbiter has nearly reached the red planet, and will undergo a 33-minute rocket burn to slow its course. Monday's big manoeuvre on Maven's engines will place the satellite in a high, elliptical, 35-hour orbit around the planet. Confirmation of capture should be received on Earth shortly after 0220 GMT (2220 EDT Sunday; 0320 BST). "We should have a preliminary answer within just a few minutes after the end of the burn," said [principal investigator professor Bruce] Jakosky. In the coming weeks, engineers will then work to bring Maven into a regular 4.5-hour, operational orbit that takes the probe as close as 150km to Mars but also sends it out to 6,200km. India's first mission to Mars faces a critical test as it does a similar maneuver -- firing of a rocket to slow its travel as it approaches Mars orbit.

a collision wouldn't surprise me

For somw reason, it wouldn't surprise me if these two craft collided, despite being the only two approaching the entire planet. It just seems that any time a government spends a lot of money to do anything, it normally ends with a fail worthy of Monty Python .
