NASA Roman Telescope launches aboard SpaceX Falcon Heavy

scienceAug 30, 2026785,249

The Nancy Grace Roman Space Telescope launched Aug 30 from Kennedy Space Center aboard a SpaceX Falcon Heavy, beginning a climb toward the Sun, Earth L2 point on a roughly three-month transit. The $4.3 billion observatory carries a 300-megapixel infrared camera that will image a field wider than the full Moon and survey billions of galaxies, hundreds of black holes and dusty planet-forming disks. NASA and astronomers expect Roman to expand the known exoplanet tally from the current several thousand to more than 100,000 by using microlensing and other survey techniques. Roman’s wide, deep infrared maps will trace the distribution of dark matter via gravitational lensing, measure cosmic expansion with specific supernova observations, and probe dark energy’s effects across cosmic time. A U.S. Space Force official said the launch-day weather forecast was 50 percent favorable; backup launch windows were set for the next two mornings. Commissioning begins while Roman is en route to L2 and its data releases will drive follow-on studies of galaxy evolution, dark matter mapping and an enlarged exoplanet census.

The telescope has been set free in space! Successful deployment! #Roman

Yes YES The telescope is out

And Dominic is crushing it on the broadcast! (Megan too, but I never worked with her.)

Thank you for that. Been very little information about Roman considering the scale of operation!!

Exciting to anticipate the kinds of discoveries #Roman may produce. The slow peeling back of the mysteries of the cosmos is at the heart of science.

I remember watch the Gemini launches in grade school when the lift-off occurred later in the morning. They'd gather three classes together and wheel in a television. Everyone was so excited. Deployment of Nancy Grace Roman Space Telescope is just as exciting to me. Amazing.

Nice to see a space telescope being successfully rewilded. Too often science instruments like this are euthanized because smaller predatory private satellites have encroached on their native habitat.

Darryl Mott2

Fly, little (actually huge) telescope! Give me science! I have a space opera idea I've put on hold entirely because I'm not sure if Nancy Grace and Euclid will confirm it as plausible or prove it wrong. So I'm waiting...

Breaking: We have lift off! NASA’s Roman Telescope is on its way to deep space, embarking on a mission that could solve some of the universe’s greatest and most enduring mysteries and discover new, alien worlds.

Elons goal is to make NASA privately owned. NASA is also being held hostage by MAGA. America is messy.

altie-a-alterson.bsky.social3

Keep double taking on these headlines because my stupid brain reads it as the “Nancy Grace” roman telescope.

The greatest mystery is how America cannot have free healthcare but can afford to subsidise billionaires. As to an alien world, look at the Trump administration and then try and tell me they aren't aliens 🙄

Roman est l'avant-dernière grande mission scientifique de la NASA développée dans les années 2010 à partir, ne reste que Dragonfly prévue en 2028. Ensuite c'est le désert. HWO et UOP ne sont pas attendus avant les années 2040, MSR annulé (SR-1 Freedom...) et la sélection de NF5 n'a même pas débuté.

Looking forward to all the new higher resolution images and data on exoplanets around other suns in the galaxy after November.

It's got the same size mirror as the Hubble, but much more sophisticated optics. I love that the National Reconnaissance Office had this sitting around in a warehouse, and offered it to NASA. en.wikipedia.org/wiki/2012_Na...

I can’t believe they named a telescope after the crazy crime lady from tv

nancy grace built a roman space telescope??

This telescope will study dark energy and dark matter. It will discover tens of thousands of exoplanets. It will picture huge swathes of the universe. It survived two attempts by the Administration to scrap it 🚀

This is the only thing that gives me hope about humanity. Our drive to colonize in space and learn more about the universe. That and our development of vaccines and drugs to help humanity.

got to see it before it left Earth and meet some of the folks working on the project and I’m so excited for everybody!!

On Sunday morning, the Nancy Grace Roman Space Telescope blasted off from the Florida coastline & sailed toward the stars. So begins its journey to capture deep, sweeping cosmic views to explore the dark universe & hunt for new worlds. www.nytimes.com/2026/08/30/s...

NASA’s latest offering to the stars follows a line of great observatories that enabled decades of discovery. It is driven by the legacy of Nancy Grace Roman, who paved the way for the agency's space astronomy program. www.nytimes.com/2026/08/28/s...

A remarkable shot by John Kraus of the launch this morning of NASA's new Nancy Grace Roman Space Telescope. Liftoff was at 7:26 am Eastern; the spacecraft will take about three months to climb up to the second Sun–Earth Lagrange point. Roman will search for dark matter, dark energy, and exoplanets.

Very curious to see what they get out of the coronagraph to image exoplanets.

Space exploration is good, as long as we keep it on Earth but what will all of this benefit humankind in the immediate future with our environment and natural resources in dire question?😒

Godspeed, Nancy Grace Roman Space Telescope. Say hi to JWST when you get to L2. Can't wait to learn what you can see from up there.

That was the loudest launch I’ve experienced in thirty eight years of living on the Space Coast.

crazy NASA is controlled by the same nazi rigging and interfering in our elections. Same nazi whose cars are killing it's drivers at a high rate. Same nazi that "we threw USAID into the wood chipper" but was spineless when the body count of his actions rose to 700k America is messy.

Nominal launch, nominal trajectory. Next up: awesome science!

I hate that we have privatized space stuff, but I am happy to see this telescope launch. My kid got to attend this in-person and is looking forward to examining the data recordings once they start coming in and are released for research. She is on the black hole side. This will also find exoplanets.

Additionally good fun watching non-space nonce rocket missions make it into space without exploding.

This is a neat view of the separation of the #Roman telescope from the rocket. Very Sci-Fi looking!

The Nancy Grace Roman Space Telescope leaves Earth behind for good. Between 2018 and 2024, the Trump Administration tried no fewer than 4 times to cancel NASA’s next flagship observatory. Congress wisely told the White House to stuff it. Science won, as it always must. Go Roman.
