How does NASA control Hubble?

Communications with Hubble are accomplished via a network interface from the STOCC to NASA’s White Sands Test Facility complex located in White Sands, New Mexico, near Las Cruces. The large antennas there transmit radio waves to NASA’s Tracking and Data Relay Satellite System (TDRSS), which forwards them to Hubble.

What signals does the Hubble telescope use to collect information about the universe?

Near-ultraviolet and near-infrared are just beyond what our eyes can see. The Advanced Camera for Surveys captures images of large areas of space. These images have helped scientists study some of the earliest activity in the universe. The Cosmic Origins Spectrograph reads ultraviolet light.

How does the Hubble telescope communicate?

To communicate with Hubble, the STOCC utilizes NASA’s Space Network. This network consists of a constellation of satellites in geosynchronous orbit named the Tracking and Data Relay Satellites (TDRS) as well as the ground facilities that support and communicate with those satellites.

What prevents the Hubble telescope from falling back into the Earth’s orbit?

Earth’s gravity is stronger in some places than others. You would think gravity was enough to deal with. But, satellites in low earth orbit such as the Hubble Space Telescope can also get pulled out of their orbit by drag from the atmosphere.

How does the Hubble telescope get its energy?

Hubble is powered by solar energy, collected by the two wing-like solar arrays seen in this image of the telescope taken during the final servicing mission in 2009. The solar arrays collect energy from the Sun, generating power for all of Hubble’s systems.

What is the purpose of the Hubble telescope?

Hubble was designed as a general purpose observatory, meant to explore the universe in visible, ultraviolet and infrared wavelengths. To date, the telescope has studied more than 40,000 cosmic objects, providing views astronomers were unable to capture from the ground.
