Servicing Mission 2
STS-82 Discovery • February 11-21, 1997
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 components increased efficiency and
