4 Min Read NASA to Embrace Commercial Sector, Fly Out Legacy Relay Fleet
An artist's concept of commercial and NASA space relays. Credits: NASA/Morgan Johnson NASA is one step closer on its transition to using commercially owned and operated satellite communications services to provide future near-Earth space missions with increased service coverage, availability, and accelerated science and data delivery.
As of Friday, Nov. 8, the agency’s legacy TDRS (Tracking and Data Relay Satellite) system, as part of the Near Space Network, will support only existing missions while new missions will be supported by future commercial services.
“There have been tremendous advancements in commercial innovation since NASA launched its first TDRS satellite more than 40 years ago,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) program. “TDRS will continue to provide critical support for at least the next decade, but now is the time to embrace commercial services that could enhance science objectives, expand experimentation, and ultimately provide greater opportunities for discovery.”

Just as NASA has adopted commercial crew, commercial landers, and commercial transport services, the Near Space Network, managed by NASA’s SCaN, will leverage private industry’s vast investment in the Earth-based satellite communications market, which includes communications on airplanes, ships, satellite dish television, and more. Now, industry is developing a new space-based market for these services, where NASA plans to become one of many customers, bolstering the domestic space industry.
NASA’s Communications Services Project is working with industry through funded Space Act Agreements to develop and demonstrate commercial satellite communications services that meet the agency’s mission needs, and the needs of other potential users.
In 2022, NASA provided $278.5 million in funding to six domestic partners so they could develop and demonstrate space relay communication capabilities.

NASA/Morgan Johnson A successful space-based commercial service demonstration would encompass end-to-end testing with a user spacecraft for one or more of the following use cases: launch support, launch and early operations phase, low and high data rate routine missions, terrestrial support, and contingency services. Once a demonstration has been completed, it is expected that the commercial company would be able to offer their services to government and commercial users.
NASA also is formulating non-reimbursable Space Act Agreements with members of industry to exchange capability information as a means of growing the domestic satellite communications market. The Communications Services Project currently is partnered with Kepler Communications US Inc. through a non-reimbursable Space Act Agreement.
As the agency and the aerospace community expand their exploration efforts and increase mission complexity, the ability to communicate science, tracking, and telemetry data to and from space quickly and securely will become more critical than ever before. The goal is to validate and deliver space-based commercial communications services to the Near Space Network by 2031, to support future NASA missions.
NASA’s Tracking and Data Relay System
While TDRS will not be accepting new missions, it won’t be retiring immediately. Current TDRS users, like the International Space Station, Hubble Space Telescope, and many other Earth- and universe-observing missions, will still rely on TDRS until the mid-2030s. Each TDRS spacecraft’s retirement will be driven by individual health factors, as the seven active TDRS satellites are expected to decline at variable rates.

NASA The TDRS fleet began in 1983 and consists of three generations of satellites, launching over the course of 40 years. Each successive generation of TDRS improved upon the previous model, with additional radio frequency band support and increased automation.
The first TDRS was designed for a mission life of 10 years, but lasted 26 years before it was decommissioned in 2009. The last in the third generation – TDRS-13 –was launched Aug. 18, 2017.
The TDRS constellation has been a workhorse for the agency, enabling significant data transfer and discoveries.”

A preview image of the Minecraft world inspired by NASA’s James Webb Space Telescope. Credit: Minecraft NASA invites gamers, educators, and students to grab their pickaxe and check out its latest collaboration with Minecraft exploring a new world inspired by the agency’s James Webb Space Telescope. The partnership allows creators to experience NASA’s discoveries with interactive modules on star formation, planets, and galaxy types, modeled using real Webb images.
The James Webb Space Telescope Challenges were developed to inspire the next generation of scientists, engineers, and technicians. Through the game, students can immerse themselves in the science and technology behind Webb, deepening their understanding of NASA’s mission and sparking an interest in the real-world applications of science, technology, engineering, and math (STEM).
“We’re thrilled to bring the wonders and science of NASA’s James Webb Space Telescope into the hands of the Artemis Generation through this exciting Minecraft collaboration,” said NASA Deputy Administrator Pam Melroy. “This collaboration is yet another way anyone can join NASA as we explore the secrets of the universe and solve the world’s most complex problems, making space exploration engaging for learners of all ages.”
NASA’s James Webb Space Telescope launched to space Dec. 25, 2021, and has gone on to make detailed observations of the planets within our own solar system, peer into the atmospheres of planets orbiting other stars outside our solar system, and capture images and spectra of the most distant galaxies ever detected.
“NASA’s collaboration with Minecraft allows players to experience the excitement of one of the most ambitious space missions ever,” said Mike Davis, Webb project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “No matter where Webb looks, it sees something intriguing, setting the stage for amazing discoveries yet to come. As people explore the Minecraft world of Webb, we hope they will be inspired to carry that interest further and maybe someday help NASA build future space telescopes.”
Webb is the world’s premier space science observatory. The space telescope is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
NASA’s Office of STEM Engagement provides unique opportunities for students to learn about STEM. In 2023, NASA partnered with Minecraft on an Artemis Challenge where users could build and launch a rocket, guide their Orion spacecraft, and even establish a lunar base alongside their team. Through collaboration with partners such as Microsoft, NASA can share the excitement of space exploration with even more students who are part of the Artemis Generation.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A major component of NASA’s Nancy Grace Roman Space Telescope just took a spin on the centrifuge at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Called the Outer Barrel Assembly, this piece of the observatory is designed to keep the telescope at a stable temperature and shield it from stray light.
This structure, called the Outer Barrel Assembly, will surround and protect NASA’s Nancy Grace Roman Space Telescope from stray light that could interfere with its observations. In this photo, engineers prepare the assembly for testing.NASA/Chris Gunn The two-part spin test took place in a large, round test chamber. Stretching across the room, a 600,000-pound (272,000-kilogram) steel arm extends from a giant rotating bearing in the center of the floor.
The test itself is like a sophisticated version of a popular carnival attraction, designed to apply centrifugal force to the rider — in this case, the outer covering for Roman’s telescope. It spun up to 18.4 rotations per minute. That may not sound like much, but it generated force equivalent to just over seven times Earth’s gravity, or 7 g, and sent the assembly whipping around at 80 miles per hour.
“We couldn’t test the entire Outer Barrel Assembly in the centrifuge in one piece because it’s too large to fit in the room,” said Jay Parker, product design lead for the assembly at Goddard. The structure stands about 17 feet (5 meters) tall and is about 13.5 feet (4 meters) wide. “It’s designed a bit like a house on stilts, so we tested the ‘house’ and ‘stilts’ separately.”
The “stilts” went first. Technically referred to as the elephant stand because of its similarity to structures used in circuses, this part of the assembly is designed to surround Roman’s Wide Field Instrument and Coronagraph Instrument like scaffolding. It connects the upper portion of the Outer Barrel Assembly to the spacecraft bus, which will maneuver the observatory to its place in space and support it while there. The elephant stand was tested with weights attached to it to simulate the rest of the assembly’s mass.
This photo shows a view from inside the Outer Barrel Assembly for NASA’s Nancy Grace Roman Space Telescope. The inner rings, called baffles, will help protect the observatory’s primary mirror from stray light.NASA/Chris Gunn Next, the team tested the “house” — the shell and a connecting ring that surround the telescope. These parts of the assembly will ultimately be fitted with heaters to help ensure the telescope’s mirrors won’t experience wide temperature swings, which make materials expand and contract.
To further protect against temperature fluctuations, the Outer Barrel Assembly is mainly made of two types of carbon fibers mixed with reinforced plastic and connected with titanium end fittings. These materials are both stiff (so they won’t warp or flex during temperature swings) and lightweight (reducing launch demands).
If you could peel back the side of the upper portion –– the house’s “siding” –– you’d see another weight-reducing measure. Between inner and outer panels, the material is structured like honeycomb. This pattern is very strong and lowers weight by hollowing out portions of the interior.
Designed at Goddard and built by Applied Composites in Los Alamitos, California, Roman’s Outer Barrel Assembly was delivered in pieces and then put together in a series of crane lifts in Goddard’s largest clean room. It was partially disassembled for centrifuge testing, but will now be put back together and integrated with Roman’s solar panels and Deployable Aperture Cover at the end of the year.
In 2025, these freshly integrated components will go through thermal vacuum testing together to ensure they will withstand the temperature and pressure environment of space. Then they’ll move to a shake test to make sure they will hold up against the vibrations they’ll experience during launch. Toward the end of next year, they will be integrated with rest of the observatory.

The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

Sols 4325-4326: (Not Quite) Dipping Our Toes in the Sand
NASA’s Mars rover Curiosity captured this image using its Left Navigation Camera on Sol 4323 — Martian day 4,323 of the Mars Science Laboratory mission — on Oct. 4, 2024, at 00:29:40 UTC. NASA/JPL-Caltech Earth planning date: Friday, Oct. 4, 2024
If you read this blog very often, you know that nearly every time the rover stops for science, MAHLI and APXS focus on interesting (and accessible!) rocks as targets. The rover science team is, after all, built with a lot of geologists. But geology is not all rocks, all the time — sand is former rock that if buried and pressurized long enough will become rock again. Today was time for sand to shine, as the workspace was cut by troughs of sand of different colors and brightnesses, and it had been nearly 500 sols since we acquired our last dedicated sand measurement with APXS and MAHLI. The “Pumice Flat” target was one of the brighter sand patches while “Kidney Lake” was one of the darker sand patches. APXS uses a special placement mode over sand targets so the instrument gets close, but not too close, to the loose material which could foul up the instrument. Not-rock was also the purview of our environmental observations. Navcam is scheduled for imaging seeking out clouds and dust devils, and changes in the sand and dust on top of the rover deck. Both Navcam and Mastcam will make observations to measure the amount of dust in the atmosphere. REMS will keep track of our weather with regular measurements, RAD will monitor our radiation environment, and DAN will look through rock for signs of water beneath our drive path.
Unsurprisingly, the rest of the rover could not ignore bedrock. We managed to squeeze in DRT cleaning of a nice bedrock slab, “Ribbon Fall,” for MAHLI-only imaging. In places, the bedrock slabs were cut by thin veins of darker gray material, similar to dark gray materials we saw in the bedrock on the other side of Gediz Vallis. ChemCam targeted one of these dark gray examples at “Black Divide,” and also rastered across some of the prominent layers visible in the vertical faces in the workspace at the aptly named “Profile View.”
Our imaging efforts could be roughly divided between looking back at our path through Gediz Vallis from our new and higher perspective, and looking ahead to what awaits us. ChemCam planned RMI mosaics back toward a field of the white stones we spent time studying in Gediz Vallis and toward a part of the edge of Gediz Vallis that we did not explore previously. Mastcam looked back at the part of the edge of Gediz Vallis we just traversed, “Pilot Peak,” for clues as to why it sits higher than the bedrock farther from the channel edge. They also targeted “Clyde Spires,” which was a gravel ridge in Gediz Vallis of interest as we drove by it initially. Looking ahead, Mastcam imaged a puzzling gray rock sitting atop the bedrock slabs south of us at target “Buena Vista Grove,” and further south still, they planned a large mosaic covering a very big rock — the spectacular “Texoli” butte that has loomed and will continue to loom over our path for months to come.

NASA Administrator Bill Nelson, left, and Kirk Johnson, Sant director, the Smithsonian’s National Museum of Natural History, preview NASA’s new Earth Information Center at the museum in Washington on Oct. 7, 2024. The exhibit includes a video wall displaying Earth science data visualizations and videos, an interpretive panel showing Earth’s connected systems, information on our changing world, and an overview of how NASA and the Smithsonian study our home planet.Credit: NASA/Bill Ingalls NASA Administrator Bill Nelson joined the director of the Smithsonian’s National Museum of Natural History in Washington and agency leadership to unveil the new Earth Information Center exhibit during an early preview on Monday.
“NASA has studied Earth and our changing climate for more than 60 years. The Earth Information Center at the Smithsonian Museum of Natural History will expand access to NASA’s data and our decades of Earth observation to even more people,” said Nelson. “Together with the Smithsonian, we are providing detailed, usable, and scalable information to enable the public to better understand the climate crisis and take action in their community.”
The exhibit includes a 32-foot-long, 12-foot-high video wall displaying Earth science data visualizations and videos, interpretive panels showing Earth’s connected systems, information on our changing world, and an overview of how NASA and the Smithsonian study our home planet. It opens to the public Tuesday, Oct. 8.
“The new Earth Information Center at the National Museum of Natural History will bring Smithsonian and NASA data on the Earth’s environment and climate to thousands of museum visitors every year,” said Kirk Johnson, the museum’s Sant director. “It is an honor to partner with NASA to bring this dynamic view of Earth to museumgoers and connect people more deeply with their home planet.”
Visitors also can explore Earth observing missions, changes in Earth’s landscape over time, and how climate is expected to change regionally through multiple interactive experiences. The exhibit will remain on display through 2028.
“The Earth Information Center allows people to see our planet as we at NASA see it – an awe-inspiring and complex system of oceans, land, ice, atmosphere, and the life they support,” said Karen St. Germain, division director, Earth Sciences Division at NASA Headquarters in Washington. “We are thrilled that this collaboration puts NASA’s Earth science at the fingertips of Smithsonian visitors for the benefit of all.”
With more than two dozen missions in orbit, NASA observes our planet’s oceans, land, ice, and atmosphere, and measure how a change in one drives change in others. NASA develops new ways to build long-term data records of how our planet evolves. The agency freely shares this unique knowledge and works with institutions around the world.
As part of NASA’s ongoing mission to better understand our home planet, NASA created the Earth Information Center which draws insights from across all NASA centers and its federal partners – the National Oceanic and Atmospheric Administration, U.S. Geological Survey, U.S. Department of Agriculture, U.S. Agency for International Development, Environmental Protection Agency, and Federal Emergency Management Administration. It allows viewers to see how our home planet is changing and gives decision makers information to develop the tools they need to mitigate, adapt, and respond to those changes.
NASA’s Earth Information Center is a virtual and physical space designed to aid people to make informed decisions on Earth’s environment and climate. It provides easily accessible Earth information, enabling global understanding of our changing planet.
The expansion of the physical Earth Information Center at the Smithsonian National Museum of Natural History makes it the second location in the Washington area. The first is located at NASA Headquarters in Washington at 300 E St., SW.
