NASA’s Nancy Grace Roman Space Telescope, aboard a SpaceX Falcon Heavy rocket, transits the Sun during launch from the agency’s Kennedy Space Center in Florida on Aug. 30, 2026. Roman is named after the agency’s first chief astronomer.
Roman will survey billions of stars and galaxies with a field of view far larger than Hubble’s, helping scientists study dark energy, exoplanets, and the evolution of the universe.

Where is Roman?
Roman is making its three-month journey from Earth to Sun-Earth Lagrange Point 2, or L2. Along the way, Roman is undergoing a process called commissioning, where systems are turned on, adjusted, calibrated, and prepared for science operations. Commissioning is the time for scientists and engineers to make sure that Roman is performing as expected. The schedule is subject to change as the team assesses and adjusts as needed.
Deployments
An hour and 23 minutes after launch, Roman began to emerge from the tight configuration that allowed it to fit in the rocket fairing. The solar panels and sunshade deployed, shading the rest of the observatory and providing power to the systems. Within the upcoming days, the antenna will swing out and the visor-like deployable aperture cover will move into place to permanently reveal and shade the primary mirror.
Roman’s Orbit
This visualization shows the stable, halo orbit that Roman will have around L2. At this location, the gravity of the Sun and Earth, together with an object’s motion around the Sun, let it stay lined up with Earth as they orbit, allowing Roman to have a relatively steady orbit without using much fuel. This location also offers exceptionally stable optical performance and a constant, unobstructed view of a wide swath of the sky; Earth won’t block much of Roman’s view since it will be so distant. And at L2, heat from Earth, the Sun, and the Moon have less effect on infrared telescopes, which “see” heat.

APOD: 2026 August 31 – Launch of the Roman Space Telescope
APOD
Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Launch of the Roman Space Telescope
Explanation: A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST’s main mirror is more curved, its secondary mirror is closer, and its main camera is larger. The result is that RST can inspect more of the sky more quickly, likely allowing, among other capabilities, the discovery of many more supernovas which tell us more about the expansion rate and composition of our universe, and many more planets orbiting other stars that tell us more about the possibilities for life elsewhere in the universe. RST will orbit the Sun, not the Earth, like the James Webb Space Telescope. The featured video shows Roman being launched yesterday from Kennedy Space Center, Florida, USA aboard a SpaceX Falcon Heavy rocket.

New Next-Gen Dish Adds Muscle to NASA’s Deep Space Network
Antennas soak in the summer Sun in August 2026 at the Deep Space Network’s Goldstone complex near Barstow, California, including the recently completed Deep Space Station 23 (shown in the foreground, to the right).
NASA/JPL-Caltech
NASA’s Deep Space Network facility in California is marking the addition of a brand new 34-meter-wide (114-foot-wide) radio frequency antenna to the agency’s deep space communications and navigation system. The network uses giant dish antennas located at three global facilities to support more than 40 spacecraft exploring the solar system and interstellar space.
The new Deep Space Station 23 (DSS-23) is located at the Goldstone Deep Space Communications Complex, near Barstow, and is managed by NASA’s Jet Propulsion Laboratory in Southern California.
NASA leadership and personnel as well as dignitaries gathered at the complete DSS-23 antenna for a ceremonial ribbon cutting. It’s the latest to be added as part of the Deep Space Network’s Aperture Enhancement Project, which began in 2009 to upgrade and expand the network by adding six new 34-meter multifrequency beam-waveguide antennas. These versatile dishes can enhance many missions operating over different radio frequencies.
“By expanding the Deep Space Network, we are strengthening the communications foundation NASA needs for the bold missions ahead — from exploring more of the Moon than ever before to peering deeper into the solar system,” said James Kenyon, associate administrator of the Research and Technology Mission Directorate at NASA Headquarters in Washington. “This new antenna will help us deliver on our national goals for space exploration and push beyond the limits of what once seemed impossible.”
After completing a testing campaign from May through July to demonstrate its capabilities, the new DSS-23 began operations on Aug. 3, tracking NASA’s Chandra X-ray Observatory. Since then, it has been communicating with dozens of missions such as NASA’s Mars Reconnaissance Orbiter, Psyche, Juno, Voyager 1, and other robotic spacecraft in deep space.
Long shadows are cast by the recently completed Deep Space Station 23 at the Deep Space Network’s Goldstone complex near Barstow, California. A multifrequency beam waveguide antenna, DSS-23 will boost the DSN’s capacity and enhance NASA’s deep space communications capabilities for decades to come.

“The addition of this next-generation antenna brings us closer to a completely modernized network that embraces advanced technology to ensure NASA’s leadership in deep space communications,” said Dave Gallagher, director of JPL. “After over 60 years of continuous operations supporting consequential missions, these upgrades prime the network for a new era of exploration. The teams that designed, planned, and built DSS-23 should be proud.”
Enhanced capabilities
Construction of DSS-23 began in February 2020. After the 133-ton metal reflector framework was placed and bolted atop the antenna’s pedestal in December 2024, engineers installed the panels to the framework that reflect radio frequency signals transmitted to and received from spacecraft. Then came the careful process of calibrating the antenna so it can work in concert with the rest of the network.
It is the fifth antenna at Goldstone (joining three 34-meter antennas and one 70-meter, or 230-foot, antenna) and the fifth enhancement project antenna to join the network, which includes antennas at the DSN’s Goldstone, Madrid, and Canberra, Australia, complexes. Multifrequency beam waveguide antennas direct signals down to a stable, climate-controlled underground room, rather than housing heavy, sensitive electronic equipment on the moving antenna dish. In addition to offering versatility, this design allows easy access for maintenance and upgrades to the system.
“The biggest challenge wasn’t actually constructing the antenna. It was transforming a complex collection of mechanical, electrical, software, radio frequency, and infrastructure systems into a single, mission-ready asset,” said Germaine Aziz, manager of the Deep Space Network Aperture Enhancement Project at JPL. “Every subsystem must be integrated, calibrated, and verified to operate with extraordinary precision and reliability before it can support NASA’s deep space missions.”
The enhancement project will be complete when a sixth enhancement-project antenna, Deep Space Station 33, comes online at the Canberra facility in 2029, bringing the total number of 34-meter antennas across the network to 13. The 34-meter antennas can be arrayed (combined and operated together) to provide an equivalent communications backup for each facility’s single 70-meter antenna, which, after more than 50 years of near-continuous operation, are getting increasingly costly to maintain and repair.
Managed by Caltech for NASA, JPL manages the agency’s Deep Space Network with the oversight of NASA’s SCaN (Space Communications and Navigation) Program within NASA’s Research and Technology Mission Directorate. More than 100 NASA and non-NASA missions rely on the Deep Space Network and Near Space Network. They include missions that support astronauts aboard the International Space Station and future Artemis missions, monitoring Earth, exploring the Moon, and exploring the solar system and beyond.
