Secret Space Escapes

In 1997 astronauts and cosmonauts Alexsandr on MIR deals with a life-threatening cabin fire and an out-of-control cargo ship; In 2001 astronaut Chris Hadfield's rookie spacewalk takes a terrifying turn leaving him temporarily blinded in space.

In 1997 on board the Russian Space Station Mir a collision put a hole in the station and the vacuum of space bares down; another astronaut's first spacewalk becomes a nightmare when he and his partner have only the oxygen in their suits to survive.

A Space Shuttle crew discovers damage to protective tiles on the shuttle's underbelly that could kill them during re-entry in temperatures up to 3000 degrees.

A toxic ammonia leak endangers a crew; and a space walk goes wrong when an astronaut's helmet fills with water. Also: a cosmonaut is stranded in the wilderness after narrowly surviving re-entry.

An astronaut loses his vision and is locked outside his craft after a spacesuit malfunction during a spacewalk; a fire on the launchpad threatens cosmonauts; and a space shuttle is aborted seconds before launch, but the crew doesn't know why.

A toxic leak threatens the lives of astronauts; a crew suffers from depressurization; and an engine malfunctions at takeoff.
