NASA's Nancy Grace Roman Space Telescope launched at 7:26 a.m. EDT on Aug. 30 from Launch Complex 39A at Kennedy Space Center aboard a SpaceX Falcon Heavy.

The telescope separated from the upper stage 31 minutes after liftoff and began flying on its own. Solar panel and instrument deployments followed, and controllers at Goddard Space Flight Center reported telemetry arriving with all systems nominal.

Size and destination

Roman is about the size of a tour bus. Its destination lies roughly a million miles from Earth, and the transit will take considerable time.

That region, where solar and terrestrial gravity balance, offers a stable thermal environment favourable to infrared observation.

What it will look at

The mission's core is wide-field survey observation. Targets range from dark matter and dark energy to exoplanets, and from solar system objects to galaxies at the edge of the observable universe.

Repeatedly imaging wide areas to catch small changes is a different role from telescopes that stare deeply at individual objects.

What follows

After arrival, the observatory must go through alignment and commissioning before routine science begins — typically a matter of months.

A successful launch is not a successful mission. Optical alignment and cooling stages remain, and problems have surfaced at that point on past missions.

Release of the data

Data from large surveys is generally released after a set period and then analysed by institutions and universities worldwide.

Astronomy is a strongly collaborative field internationally, and data release policy shapes the research ecosystem around it.
