Hubble space telescope orbiting the Earth focusing on the black high-gain antenna

Hubble High-gain Antenna

This photo, taken during Servicing Mission 3B, shows one of Hubble’s two high-gain antennas (black dish near center) in the stowed position while the telescope was docked in the shuttle’s cargo bay. One of the cone-shaped, low-gain antennas can also be seen in the upper right.
