The astronaut servicing team must carry out the first ever in-space repairs of Hubble’s defective instruments, a task that requires ingenious engineering fixes and the most intensive NASA spacewalk ever. NOVA presents the inside story of the mission and the extraordinary challenges faced by the rescue crew.
