This enormous piece of space hardware is NASA’s Nancy Grace Roman Space Telescope’s spacecraft bus, which will maneuver the observatory to its place in space and enable it to function while there. It is photographed here in the largest clean room at NASA’s Goddard Space Flight Center, where engineers are inspecting it upon delivery. The bus rests atop an aluminum ring that will temporarily protect its underside. The two copper-colored flaps are Roman’s Lower Instrument Sun Shade –– deployable panels designed to help shield the observatory from sunlight.NASA/Chris Gunn The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.
Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself.
“They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said Jackie Townsend, the Roman deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s really more like an RV because it has a whole assortment of functions that enable Roman to accomplish its scientific goals while out there too.”
Those goals include surveying wide swaths of the universe to study things like: dark energy, a mysterious cosmic pressure thought to accelerate the universe’s expansion; dark matter, invisible matter seen only via its gravitational influence; and exoplanets, worlds beyond our solar system.
The mission’s science wouldn’t be possible without a spacecraft to transport the telescope, point the observatory toward different cosmic targets, provide power, communicate with Earth, control and store instrument data, and regulate Roman’s temperature. Nearly 50 miles of electrical cabling are laced throughout the assembly to enable different parts of the observatory to communicate with each other.
The spacecraft will also deploy several major elements that will be stowed for launch, including the solar panels, deployable aperture cover, lower instrument Sun shade, and high-gain antenna. It’s also responsible for collecting and beaming down data, which is no small task for a space observatory that will survey the cosmos like Roman will.
“Roman will send back 1.4 terabytes of data per day, compared to about 50 to 60 gigabytes from the James Webb Space Telescope and three gigabytes from the Hubble Space Telescope,” said Jason Hylan, the Roman observatory manager at NASA Goddard. “Webb’s daily downlink is roughly comparable to 13 hours of YouTube video at the highest quality while Roman’s would amount to about 2 weeks.”

It rests atop an aluminum ring that will not be part of the observatory and is surrounded by an enclosure used in testing to ensure electromagnetic interference will not affect the bus’s sensitive electronics. The bus is covered in gray bagging material to prevent contamination –– even tiny stray particles could affect its performance.NASA/Chris Gunn A Goddard Grand Slam
This milestone is the culmination of eight years of spacecraft design work, building, and testing by hundreds of people at Goddard.
“Goddard employees were the brains, designers, and executors. And they worked with vendors who supplied all the right parts,” Townsend said. “We leaned on generations of expertise in the spacecraft arena to work around cost and schedule challenges that arose from supply chain issues and the pandemic.”
One time- and money-saving technique the team came up with was building a spacecraft mockup, called the structural verification unit. That allowed them to do two things at once: complete strength testing on the mockup, designed specifically for that purpose, while also assembling the actual spacecraft.
The spacecraft’s clever layout also allowed the team to adapt to changing schedules. It’s designed to be modular, “more like Trivial Pursuit pie pieces than a nesting egg, where interior components are buried inside,” Townsend said. “That’s been a game-changer because you can’t always count on things arriving in the order you planned or working perfectly right away with no tweaks.” It also increased efficiency because people could work on different portions of the bus at the same time without interfering with each other.
The slightly asymmetrical and hexagonal spacecraft bus is about 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms).
While it may look small in this photo, the spacecraft bus for NASA’s Nancy Grace Roman Space Telescope is 8 feet (2.5 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms). In this photo, it rests atop an aluminum ring that will not be part of the observatory. The bundles of wires on top are part of more than 50 miles of cabling laced throughout the assembly to enable different parts of the observatory to communicate with each other.NASA/Chris Gunn One reason it doesn’t weigh more is that some components have been partially hollowed out. If you could peel back some of the spacecraft’s panels, you’d find superthin metallic honeycomb sandwiched between two slim layers of metal. And many of the components, such as the antenna dish, are made of strong yet lightweight composite materials.
When the spacecraft bus was fully assembled, engineers conducted a comprehensive performance test. Prior to this, each component had been tested individually, but just like with a sports team, the whole unit has to perform well together.
“The spacecraft passed the test, and now we’re getting ready to install the payload –– Roman’s instruments and the telescope itself,” said Missie Vess, a spacecraft systems engineer for Roman at NASA Goddard. “Next year, we’ll test these systems together and begin integrating the final components of the observatory, including the deployable aperture cover, outer barrel assembly, and solar panels. Then we’ll finally have ourselves a complete observatory, on track for launch by May 2027.”

The Sun rises above the Flight Research Building at NASA’s Glenn Research Center in Cleveland.Credit: NASA NASA‘s Watts on the Moon Challenge, designed to advance the nation’s lunar exploration goals under the Artemis campaign by challenging United States innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions, concludes on Friday, Sept. 20, at the Great Lakes Science Center in Cleveland.
“For astronauts to maintain a sustained presence on the Moon during Artemis missions, they will need continuous, reliable power,” said Kim Krome-Sieja, acting program manager, Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “NASA has done extensive work on power generation technologies. Now, we’re looking to advance these technologies for long-distance power transmission and energy storage solutions that can withstand the extreme cold of the lunar environment.”
The technologies developed through the Watts on the Moon Challenge were the first power transmission and energy storage prototypes to be tested by NASA in an environment that simulates the extreme cold and weak atmospheric pressure of the lunar surface, representing a first step to readying the technologies for future deployment on the Moon. Successful technologies from this challenge aim to inspire, for example, new approaches for helping batteries withstand cold temperatures and improving grid resiliency in remote locations on Earth that face harsh weather conditions.
Media and the public are invited to attend the grand finale technology showcase and awards ceremony for the $5 million, two-phase competition. U.S. and international media interested in covering the event should confirm their attendance with Lane Figueroa by 3 p.m. CDT Tuesday, Sept. 17, at: lane.e.figueroa@nasa.gov. NASA’s media accreditation policy is available online. Members of the public may register as an attendee by completing this form, also by Friday, Sept. 17.
During the final round of competition, finalist teams refined their hardware and delivered a full system prototype for testing in simulated lunar conditions at NASA’s Glenn Research Center in Cleveland. The test simulated a challenging power system scenario where there are six hours of solar daylight, 18 hours of darkness, and the user is three kilometers from the power source.
“Watts on the Moon was a fantastic competition to judge because of its unique mission scenario,” said Amy Kaminski, program executive, Prizes, Challenges, and Crowdsourcing, Space Technology Mission Directorate at NASA Headquarters in Washington. “Each team’s hardware was put to the test against difficult criteria and had to perform well within a lunar environment in our state-of-the-art thermal vacuum chambers at NASA Glenn.”
Each finalist team was scored based on Total Effective System Mass (TESM), which determines how the system works in relation to its mass. At the awards ceremony, NASA will award $1 million to the top team who achieves the lowest TESM score, meaning that during testing, that team’s system produced the most efficient output-to-mass ratio. The team with the second lowest mass will receive $500,000. The awards ceremony stream live on NASA Glenn’s YouTube channel and NASA Prize’s Facebook page.
The Watts on the Moon Challenge is a NASA Centennial Challenge led by NASA Glenn. NASA Marshall manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA has contracted HeroX to support the administration of this challenge.

Image Credit: BitGrit The Digital Information Platform (DIP) Sub-Project of Air Traffic Management – eXploration (ATM-X) is seeking to make available in the National Airspace System a variety of live data feeds and services built on that data. The goal is to allow external partners to build advanced, data-driven services using this data, and to make these services available to flight operators, who will use these capabilities to save fuel and avoid delays. Different wind directions, weather conditions at or near the airport, inoperative runway, etc., affects the runway configurations to be used and impacts the overall arrival throughputs. Knowing the arrival runway and its congestion level ahead of time will enable aviation operators to perform a better flight planning and improve the flight efficiency. This competition seeks to make better predictions of runway throughputs using machine learning or other techniques. This competition engages students, faculty members and other individuals employed by United States universities to develop a machine learning model that provides a short-term forecast of estimated airport runway throughput using simulated real-time information from historical NAS and weather forecast data, as well as other factors such as meteorological conditions, airport runway configuration, and airspace congestion.
Award: $120,000 in total prizes

NASA’s Artemis campaign is a series of lunar missions to further explore the lunar landscape to prepare for future missions to Mars. The Artemis missions will send humans to land on the moon and explore the lunar south pole. This will be NASA’s first human lunar landing since the Apollo missions over 50 years ago. The Artemis missions will be landing at the lunar south pole; this area is of interest because the permanently shadowed regions that exist there may be traps for water ice which could be accessed to support future missions to Mars. One area of interest is Shackleton Crater, measuring 13 miles (21 km) in diameter and 2.6 miles (4.2 km) deep. The crater has steep sides and continuous shadows cause the floor of the crater to be below 90 K and may have water ice trapped beneath the surface. To support these missions, NASA is seeking two solutions: one low-tech and one high-tech. While both solutions are related to navigation, they are independent challenges and solutions. For Challenge 1, NASA is seeking an orienteering aid that will help the astronauts navigate on traverses away from the lunar lander and return back. While there were similar devices available to the Apollo astronauts, NASA is looking for new and unique solutions. Among other considerations, devices must be accurate, easy to use, able to be used on the moon’s surface by an astronaut wearing pressurized gloves. If your solution is one of the best, you could be eligible for a share of the $15,000 prize purse. For Challenge 2, NASA is looking for assistance in getting to and mapping the bottom of Shackleton Crater. The design must work in the extreme conditions of the lunar south pole and Shackleton Crater, map the crater, characterize and quantify what is in the crater, and send the data back to be used for future missions. If you can solve this challenge by describing your design concept in detail, you could be eligible for a share of the $30,000 prize purse.
