Level 1 - Absolute Beginner
NASA sent a new space telescope into space. It is called the Nancy Grace Roman Space Telescope. It went up on Sunday, August 30, 2026, at 7:26 in the morning.
A big rocket called a Falcon Heavy carried the telescope. The rocket launched from Kennedy Space Center in Florida.
The telescope will travel for about three months. It will go about one million miles. It will not orbit Earth. It will orbit the Sun instead, far out in space.
This telescope will look for dark matter and dark energy. These are mysterious things in space that we cannot see, but scientists know they are there. The telescope will also look for exoplanets, which are planets that go around other stars, not our Sun.

Level 2 - Elementary
NASA's Nancy Grace Roman Space Telescope launched on Sunday, August 30, 2026, lifting off at 7:26 a.m. EDT. A SpaceX Falcon Heavy rocket carried it into space from Launch Complex 39A at NASA's Kennedy Space Center in Florida.
The telescope is now on a journey that will take roughly three months and cover about one million miles. It is heading to a point in space known as the Sun-Earth L2 point, where it will orbit the Sun rather than the Earth. The James Webb Space Telescope also orbits in that same general region.
The telescope is named after Nancy Grace Roman, who was NASA's first chief astronomer. She is sometimes called the 'Mother of Hubble' because of how strongly she pushed for the earlier Hubble Space Telescope to be built.
Roman's main mirror is the same size as Hubble's, but its camera can capture a view of the sky about 100 times larger than Hubble's in a single picture. This means Roman can survey much more of the sky, much faster, than Hubble ever could. Its main goals are studying dark energy and dark matter, along with searching for and studying exoplanets. NASA expects to release the telescope's first images in early 2027, after it reaches its final orbit and its instruments are calibrated.

Level 3 - Intermediate
NASA's Nancy Grace Roman Space Telescope lifted off on Sunday, August 30, 2026, at 7:26 a.m. EDT, launched aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA's Kennedy Space Center in Florida. The telescope is now embarked on a roughly three-month, million-mile voyage toward its operational post in space.
Rather than orbiting Earth as Hubble does, Roman is headed for the Sun-Earth L2 point, a gravitationally stable location where it will circle the Sun in the same general vicinity already occupied by the James Webb Space Telescope. This positioning allows the observatory to maintain a stable thermal environment and an unobstructed view of deep space, shielded from the glare and heat of both the Sun and Earth.
The telescope honors Nancy Grace Roman, NASA's first chief astronomer, whose forceful advocacy for the Hubble Space Telescope decades ago earned her the nickname the 'Mother of Hubble.' Fittingly, her namesake observatory shares Hubble's primary mirror size, yet it carries a camera capable of capturing a field of view roughly 100 times larger in a single exposure, a leap that allows Roman to survey vast stretches of sky at a pace Hubble could never match.
That combination of resolving power and breadth is central to Roman's scientific mission, which centers on probing the nature of dark energy and dark matter, the invisible forces and mass believed to govern the universe's structure and expansion, as well as detecting and characterizing exoplanets orbiting distant stars. NASA anticipates releasing the telescope's first images in early 2027, once it settles into its final orbit and its onboard instruments have been calibrated.

Level 4 - Advanced
NASA's Nancy Grace Roman Space Telescope ascended into orbit on Sunday, August 30, 2026, lifting off at 7:26 a.m. EDT atop a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. The observatory now embarks on an approximately three-month, million-mile transit toward its designated operational station, a journey that will culminate not in orbit around Earth but around the Sun itself.
Roman's destination is the Sun-Earth L2 point, a gravitationally balanced location already home to the James Webb Space Telescope, where the combined pull of the Sun and Earth allows a spacecraft to maintain a comparatively stable position with minimal fuel expenditure. The site's advantages extend beyond orbital mechanics: shielded from the thermal interference and stray light of both Earth and Sun, an observatory stationed there can sustain the extraordinarily stable, cold operating conditions that infrared and wide-field instruments require for precision work.
The telescope's namesake, Nancy Grace Roman, served as NASA's first chief astronomer and is remembered as the 'Mother of Hubble' for the sustained institutional advocacy that helped bring that earlier flagship observatory into being. Her successor instrument shares Hubble's primary mirror diameter yet marries it to a camera capable of capturing a field of view roughly a hundredfold larger in a single exposure, a design choice that trades none of Hubble's resolving power for a dramatically expanded survey capacity, enabling Roman to map far greater swaths of sky within a fraction of the time.
That architecture is purpose-built for Roman's twin scientific mandates: interrogating the nature of dark energy and dark matter, the largely unseen phenomena thought to govern the universe's structure and its accelerating expansion, and conducting wide-field searches for exoplanets orbiting stars beyond our own. NASA anticipates unveiling the telescope's first images in early 2027, once Roman has settled into its final orbital station and undergone the calibration of its onboard instruments, a milestone that will mark the transition from a successful launch to the beginning of its scientific operations.
