Just days after the reentry of the latest Cygnus cargo vehicle, Russia has lost a Progress spacecraft. Something went wrong during the third stage of the flight, and the vehicle broke up and reentered over the Tuva Republic of eastern Russia, just north of Mongolia. Most of the vehicle is believed to have burned up in the upper atmosphere. It will take time to determine exactly what happened, but initial indications suggest a premature separation of spacecraft and launch vehicle.
Progress was carrying 710 kg of propellant for Zvezda, 420 kg of water, 52 kg of oxygen, 315 kg of food, 115 kg of miscellaneous gear including medical and hygiene supplies, 83 kg of gear for the Russian segment’s toilet system, 67 kg of air purification hardware, an Orlan suit, cables, cameras, science experiements, and 87 kg of supplies for NASA (including equipment for the environmental control and water recycling systems). All of that of course has now been lost.
Consumables on the station are within comfortable margins at present. The next scheduled cargo flight is a Japanese HTV on Dec 9.
