Nancy Grace Roman Space Telescope Mission Tracker Live

This stream is a live mission tracker rather than a camera. It follows the Nancy Grace Roman Space Telescope on its journey to L2, about one and a half million kilometres from Earth, told with data rather than adjectives.

On screen are the telescope's distance from Earth, geocentric speed and one-way light time, recalculated every second from state vectors published by NASA JPL's Horizons system. Roman's position on the way to L2 is shown in two alternating views, alongside the Deep Space Network antennas currently in contact with the spacecraft according to the public DSN Now feed, and the latest official NASA updates.

## About the mission

• Named after Nancy Grace Roman, NASA's first chief of astronomy
• A wide-field infrared telescope for surveying huge areas of sky
• Designed to study dark energy, exoplanets and the structure of the universe

The L2 point is a gravitationally stable spot beyond Earth, also home to the James Webb Space Telescope. There's no physical location to show on Earth; the stream lives in space. The tracker is provided by Radio El Respeto.
