Heres how to watch NASAs Nancy Grace Roman Space Telescope launch live

If the weather plays nice, NASA plans to launch its next flagship space observatory this Sunday, and viewers can watch the coverage live online from home.

NASA and SpaceX are targeting the launch of the Nancy Grace Roman Space Telescope no earlier than 7:26 a.m.

ET on Aug.

30 at the Kennedy Space Center in Cape Canaveral, Florida.

The infrared telescope's ride, a SpaceX Falcon Heavy rocket, will lift off from the historic Launch Complex 39A pad, the same that sent Apollo 11 and the maiden voyage of the Space Shuttle into orbit.

Roman, with a lifecycle cost of about $4.3 billion, combines Hubble-like sharpness with a field of view at least 100 times larger, allowing scientists to map billions of galaxies, probe dark energy and dark matter , and discover exoplanets at an unprecedented scale.

The telescope sees the universe in infrared light, which human eyes cannot see.

Its wide surveys let astronomers track how structures, such as stars, galaxies, and galaxy clusters, grow over time, as well as measure how the universe expands.

Mission planners expect Roman images from a major survey to include more than 2 billion galaxies and, over time, reveal tens of thousands of supernova explosions and many new planets.
