Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Roman Coronagraph is integrated with the Instrument Carrier for NASA’s Nancy Grace Roman Space Telescope in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., in October 2024.NASA/Sydney Rohde
NASA’s Nancy Grace Roman Space Telescope team has successfully completed integration of the Roman Coronagraph Instrument onto Roman’s Instrument Carrier, a piece of infrastructure that will hold the mission’s instruments, which will be integrated onto the larger spacecraft at a later date. The Roman Coronagraph is a technology demonstration that scientists will use to take an important step in the search for habitable worlds, and eventually life beyond Earth.
This integration took place at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the space telescope is located and in development. This milestone follows the coronagraph’s arrival at the center earlier this year from NASA’s Jet Propulsion Laboratory (JPL) in Southern California where the instrument was developed, built, and tested.
In a clean room at NASA’s Jet Propulsion Laboratory in Southern California in October 2023, scientist Vanessa Bailey stands behind the Roman Coronagraph, which has been undergoing testing at the lab. Designed to block starlight and allow scientists to see the faint light from planets outside our solar system, the Coronagraph is a technology demonstration that will be part of the Roman telescope.NASA/JPL-Caltech The Roman Coronagraph Instrument is a technology demonstration that will launch aboard the Nancy Grace Roman Space Telescope, NASA’s next flagship astrophysics mission. Roman will have a field of view at least 100 times larger than the agency’s Hubble Space Telescope and explore scientific mysteries surrounding dark energy, exoplanets, and infrared astrophysics. Roman is expected to launch no later than May 2027.
The mission’s coronagraph is designed to make direct observations of exoplanets, or planets outside of our solar system, by using a complex suite of masks and active mirrors to obscure the glare of the planets’ host stars, making the planets visible. Being a technology demonstration means that the coronagraph’s goal is to test this technology in space and showcase its capabilities. The Roman Coronagraph is poised to act as a technological stepping stone, enabling future technologies on missions like NASA’s proposed Habitable Worlds Observatory, which would be the first telescope designed specifically to search for signs of life on exoplanets.
“In order to get from where we are to where we want to be, we need the Roman Coronagraph to demonstrate this technology,” said Rob Zellem, Roman Space Telescope deputy project scientist for communications at NASA Goddard. “We’ll be applying those lessons learned to the next generation of NASA flagship missions that will be explicitly designed to look for Earth-like planets.”

The coronagraph was successfully integrated into Roman’s Instrument Carrier, a large grid-like structure that sits between the space telescope’s primary mirror and spacecraft bus, which will deliver the telescope to orbit and enable the telescope’s functionality upon arrival in space. Assembly of the mission’s spacecraft bus was completed in September 2024.
The Instrument Carrier will hold both the coronagraph and Roman’s Wide Field Instrument, the mission’s primary science instrument, which is set to be integrated later this year along with the Roman telescope itself. “You can think of [the Instrument Carrier] as the skeleton of the observatory, what everything interfaces to,” said Brandon Creager, lead mechanical engineer for the Roman Coronagraph at JPL.
The integration process began months ago with mission teams from across NASA coming together to plan the maneuver. Additionally, after its arrival at NASA Goddard, mission teams ran tests to prepare the coronagraph to be joined to the spacecraft bus.
The Instrument Carrier for Roman is lifted during the integration of the Coronagraph in October 2024 at NASA Goddard.NASA/Sydney Rohde During the integration itself, the coronagraph, which is roughly the size and shape of a baby grand piano (measuring about 5.5 feet or 1.7 meters across), was mounted onto the Instrument Carrier using what’s called the Horizontal Integration Tool.
First, a specialized adapter developed at JPL was attached to the instrument, and then the Horizontal Integration Tool was attached to the adapter. The tool acts as a moveable counterweight, so the instrument was suspended from the tool as it was carefully moved into its final position in the Instrument Carrier. Then, the attached Horizontal Integration Tool and adapter were removed from the coronagraph. The Horizontal Integration Tool previously has been used for integrations on NASA’s Hubble and James Webb Space Telescope.
As part of the integration process, engineers also ensured blanketing layers were in place to insulate the coronagraph within its place in the Instrument Carrier. The coronagraph is designed to operate at room temperature, so insulation is critical to keep the instrument at the right temperature in the cold vacuum of space. This insulation also will provide an additional boundary to block stray light that could otherwise obscure observations.
Following this successful integration, engineers will perform different checks and tests to ensure that everything is connected properly and is correctly aligned before moving forward to integrate the Wide Field Instrument and the telescope itself. Successful alignment of the Roman Coronagraph’s optics is critical to the instrument’s success in orbit.
Team members stand together during the integration of the Roman Coronagraph in a clean room at NASA Goddard in October 2024. NASA/Sydney Rohde This latest mission milestone is the culmination of an enduring collaboration between a number of Roman partners, but especially between NASA Goddard and NASA JPL.
“It’s really rewarding to watch these teams come together and build up the Roman observatory. That’s the result of a lot of teams, long hours, hard work, sweat, and tears,” said Liz Daly, the integrated payload assembly integration and test lead for Roman at Goddard.
“Support and trust were shared across both teams … we were all just one team,” said Gasia Bedrosian, the integration and test lead for the Roman Coronagraph at JPL. Following the integration, “we celebrated our success together,” she added.
The Roman Coronagraph Instrument was designed and built at NASA JPL, which manages the instrument for NASA. Contributions were made by ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), the French space agency CNES (Centre National d’Études Spatiales), and the Max Planck Institute for Astronomy in Germany. Caltech, in Pasadena, California, manages NASA JPL for the agency. The Roman Science Support Center at Caltech/IPAC partners with NASA JPL on data management for the Coronagraph and generating the instrument’s commands.

Red Rocks with Green Spots at ‘Serpentine Rapids’
NASA’s Mars Perseverance rover acquired this image, a nighttime mosaic of the Malgosa Crest abrasion patch at “Serpentine Rapids,” using its SHERLOC WATSON camera, located on the turret at the end of the rover’s robotic arm. The diameter of the abrasion patch is 5 centimeters (about 2 inches) and the large green spot in the upper center left of the image is approximately 2 millimeters (about 0.08 inch) in diameter. Mosaic source images have been debayered, flat-fielded, and linearly color stretched. This image was acquired on Aug. 19, 2024 (sol 1243, or Martian day 1,243 of the Mars 2020 mission) at the local mean solar time of 19:45:30. NASA/JPL-Caltech After discovering and sampling the “leopard spots” of “Bright Angel,” it became apparent that Perseverance’s journey of discovery in this region was not yet finished. Approximately 20 sols (Martian days) after driving south across Neretva Vallis from Bright Angel, the rover discovered the enigmatic and unique red rocks of “Serpentine Rapids.”
At Serpentine Rapids, Perseverance used its abrading bit to create an abrasion patch in a red rock outcrop named “Wallace Butte.” The 5-cm diameter abrasion patch revealed a striking array of white, black, and green colors within the rock. One of the biggest surprises for the rover team was the presence of the drab-green-colored spots within the abrasion patch, which are composed of dark-toned cores with fuzzy, light green rims.
On Earth, red rocks — sometimes called “red beds” — generally get their color from oxidized iron (Fe3+), which is the same form of iron that makes our blood red, or the rusty red color of metal left outside. Green spots like those observed in the Wallace Butte abrasion are common in ancient “red beds” on Earth and form when liquid water percolates through the sediment before it hardens to rock, kicking off a chemical reaction that transforms oxidized iron to its reduced (Fe2+) form, resulting in a greenish hue. On Earth, microbes are sometimes involved in this iron reduction reaction. However, green spots can also result from decaying organic matter that creates localized reducing conditions. Interactions between sulfur and iron can also create iron-reducing conditions without the involvement of microbial life.
Unfortunately, there was not enough room to safely place the rover arm containing the SHERLOC and PIXL instruments directly atop one of the green spots within the abrasion patch, so their composition remains a mystery. However, the team is always on the lookout for similar interesting and unexpected features in the rocks.
The science and engineering teams are now dealing with incredibly steep terrain as Perseverance ascends the Jezero Crater rim. In the meantime, the Science Team is hanging on to the edge of their seats with excitement and wonder as Perseverance makes the steep climb out of the crater it has called home for the past two years. There is no shortage of wonder and excitement across the team as we contemplate what secrets the ancient rocks of the Jezero Crater rim may hold.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Stennis Space Center near Bay St. Louis, Mississippi, achieved a key milestone this week for testing a new SLS (Space Launch System) rocket stage to fly on future Artemis missions to the Moon and beyond.
Over a two-week period beginning Oct. 10, crews completed a safe lift and installation of the interstage simulator component needed for future testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. The component will function like the SLS interstage section that helps protect the upper stage during Artemis launches.
“NASA Stennis is at the front end of the critical path for future space exploration,” said Barry Robinson, project manager for exploration upper stage Green Run testing on the Thad Cochran Test Stand. “Installing the interstage simulator is a significant step in our preparation to ensure the new, more powerful upper stage is ready to safely fly on future Artemis missions.”

The new stage will replace the current interim cryogenic propulsion stage on the Block 1 version of SLS, which features a single engine and is capable of lifting 27 tons of crew and cargo to lunar orbit.
The new exploration upper stage will be powered by four RL10 engines, manufactured by SLS engines contractor L3Harris. It will increase payload capacity by 40%, enabling NASA to send 38 tons of cargo with a crew to the Moon or 42 tons of cargo without a crew.
In the first two weeks of October 2024, crews at NASA’s Stennis Space Center completed a successful lift and installation of an interstage simulator unit on the B-2 side of the Thad Cochran test Stand. The interstage simulator is a key component for future testing of NASA’s new exploration upper stage that will fly on Artemis missions to the Moon and beyond. Before the first flight of the exploration upper stage on the Artemis IV mission, the stage will undergo a series of Green Run tests of its integrated systems at NASA Stennis. The test series will culminate with a hot fire of the stage’s four RL10 engines, just as during an actual mission.
The simulator component installed on the Thad Cochran Test Stand (B-2) at NASA Stennis weighs 103 tons and measures 31 feet in diameter and 33 feet tall. It will function like the SLS interstage section to protect EUS electrical and propulsion systems during Green Run testing. The top portion of the simulator also will serve as a thrust takeout system to absorb the thrust of the EUS hot fire and transfer it back to the test stand. The four-engine EUS provides more than 97,000 pounds of thrust.

Installation onto the test stand enables NASA Stennis crews to begin fabricating the mechanical and electrical systems connecting the facility to the simulator. As fabrication of the systems are completed, crews will conduct activation flows to ensure the test stand can operate to meet test requirements.
Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
