The mission due to launch next year has seen the projected costs balloon to more than a billion euros. In particular, problems with the parachute have frustrated engineers as they have been unable t develop a method of safely landing the rover on the red planet’s surface. Now the ESA is appealing to NASA’s Jet Propulsion Laboratory for assistance, with trials of a new design for the parachute set to start trials in Pasadena in the new year.“It is going to be very, very tight getting the probe ready for next summer’s launch,” ExoMars project manager Pietro Baglioni told the Guardian. “I think we have only got a 50-50 chance we will be able to go ahead as scheduled.”The plan is to employ a heat shield as it travels through Mars’ upper atmosphere, which should see its speed drop from 13,000mph to near a more manageable 1000mph. At that point a couple parachutes should slow the lander further allowing the rover to reach the surface at a safe speed.“The entire sequence from atmospheric entry to landing will take only six minutes,” said Baglioni. “There is a great deal that can go wrong in that time, however.”Baglioni says that the latest tests, with NASA’s help, have gone well. “However,” he says, “the crunch will come when we repeat the high-altitude tests in February…
