Trouble.
http://www.nasaspaceflight.com/content/?cid=5375 Ariane 5 ES launches with ATV - suffers early fault on orbit Teams are evaluating a problem with ATV's Propulsion Drive Electronics (PDE) 2. The system in question controls 25 percent of the vehicle's thrusters, and would require extra prop usages for vehicle control should recovery fail. The fault is believed to related to a mismatch in ox/fuel flow rates, with a second failure sending the ATV in survival mode. All burns have been canceled until further notice. |
