The Second Servicing Mission, launched February 11, 1997, greatly improved Hubble's productivity. The installation of new instruments extended Hubble's wavelength range into the near infrared for imaging and spectroscopy, allowing us to probe the most distant reaches of the universe. The replacement of failed or degraded spacecraft components increased efficiency and performance.
A seven-member STS-82 crew took part in this mission. Four astronauts conducted the planned spacewalks: Mark Lee, Gregory Harbaugh, Steven Smith and Joseph Tanner were part of the extravehicular activity crew. Kenneth Bowersox was the commander, Scott Horowitz was the pilot, and Steven Hawley was the Remote Manipulator System Operator.
