Robotic Servicing Mission Launches with NASA Support

2026-07-22 18:04

Following its liftoff from Cape Canaveral on July 21 aboard a SpaceX Falcon 9 rocket, the Mission Robotic Vehicle (MRV) hosting the NASA-supported Robotic Servicing of Geosynchronous Satellites (RSGS) payload is now en route to geosynchronous Earth orbit, where it will use its advanced robotics to service spacecraft.

RSGS leverages in-space robotics expertise from NASA, aligned with the agency’s broader goals to advance U.S. capabilities for in-space servicing, assembly, and manufacturing that can be applied to space commerce and exploration.

Funded by the Defense Advanced Research Projects Agency (DARPA), the RSGS program uses twin dexterous robotic arms designed and developed by the U.S. Naval Research Laboratory. DARPA provided the robotic arm assembly for integration onto Northrop Grumman’s MRV, the nation’s first multi-mission robotic in-space servicer. The spacecraft will inspect and upgrade satellites in orbit by installing small propulsion modules – called mission extension pods – extending the operational life of existing spacecraft for years.

RSGS brings together government agencies and industry to test advanced robotic systems in space. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began supporting the RSGS mission in 2024 under an interagency agreement with DARPA.

NASA’s contributions to the mission leverage its legacy of servicing missions including the Hubble Space Telescope servicing missions and the Robotic Refueling Missions on the International Space Station. NASA support to RSGS program includes the development of dynamic simulation and analysis tools, software analysis for performance verification, and a team of flight robot operators who will support highly technical procedures in orbit. Hundreds of satellites are in geosynchronous orbit. Of those, fully functional satellites are often decommissioned early because they run out of fuel or their equipment becomes obsolete.  RSGS establishes a critical U.S. capability to extend the lifetime of spacecraft in orbit, allowing for more innovative and cost-effective mission designs.

NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev are wrapping up their 241‑day mission aboard the International Space Station.

The crew and its Soyuz MS-28 spacecraft will undock from the orbiting laboratory’s Rassvet module at 3:02 a.m. EDT Sunday, July 26, heading for a parachute-assisted landing at 6:26 a.m. (3:26 p.m. local time) on the steppe of Kazakhstan, southeast of Dzhezkazgan.

NASA’s live return coverage will stream through a variety of platforms. Learn where to watch online:

https://www.nasa.gov/live

Williams and his crewmates will complete 3,856 orbits and travel more than 102 million miles before returning to Earth. The flight marks the first mission for Williams and Mikaev and the second for Kud‑Sverchkov.

After landing, the crew will fly by helicopter to Karaganda, Kazakhstan, where recovery teams are based. Williams then will return to NASA’s Johnson Space Center in Houston, while Kud‑Sverchkov and Mikaev head back to their training base in Star City, Russia.

NASA’s live return coverage is as follows (all times Eastern and subject to change based on real-time operations):

Saturday, July 25

9:40 a.m. – Coverage of the Space Station Expedition 74/75 change of command ceremony begins.

Kud‑Sverchkov will transfer command of the orbital complex to NASA astronaut Jessica Meir. Expedition 75 officially begins when Soyuz MS‑28 undocks.

11:10 p.m. – Coverage of crew farewells and hatch closing begins.

11:30 p.m. – Hatch closing

Sunday, July 26

2:30 a.m. – Coverage of undocking begins.

3:02 a.m. – Undocking

5:15 a.m. – Coverage of deorbit and landing begins.

5:32 a.m. – Deorbit burn

6:26 a.m. – Landing

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

A New Look – and Sound – for Messier 94

NASA’s Chandra X-ray Observatory unveiled this new look at the galaxy NGC 4736, also known as Messier 94, on June 30, 2026. Messier 94 is a spiral galaxy with a bright inner ring around it, called a starburst ring, where new stars are forming, perhaps fueled by gas driven in the unique oval-shaped structure seen here.

In this image, X-rays of different wavelengths from Chandra (red, orange, and blue) are layered with a visible light image from astrophotographers using their telescopes on the ground (red, green, and blue).

Mapping Io’s Hidden Heat With NASA’s Juno

A spherical projection of Io overlaid with a latitude and longitude grid. Broad, curved tracks — composed of overlapping ellipses crossing the surface — are black across the center and left of the globe, transitioning to blue toward the lower right.

Description

This graphic illustrates the areas of Jupiter’s moon Io sampled by the Microwave Radiometer (MWR) instrument aboard NASA’s Juno spacecraft during two close flybys. The black overlapping lines show the instrument’s footprints during Perijove 57 on Dec. 30, 2023, when the spacecraft primarily mapped the northern hemisphere. The blue lines represent Perijove 58 on Feb. 3, 2024, which focused heavily on the moon’s mid-latitudes and equatorial regions. 

Both passes mapped the side of Io that constantly faces Jupiter. The sweeping, overlapping patterns are a result of the spacecraft spinning at two revolutions per minute as it flew past the moon at a distance of roughly 930 miles (1,500 kilometers). 

NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The MWR was built by JPL. Lockheed Martin Space in Denver built and operates the spacecraft.

NASA’s Juno Peers Beneath Io’s Surface

Description

This map represents data captured by the Microwave Radiometer (MWR) aboard NASA’s Juno spacecraft, indicating heat rising from just beneath the surface of Jupiter’s moon Io. While infrared instruments measure the temperature of the moon’s surface, the lowest frequency microwave channels (0.6 and 1.25 gigahertz) on the MWR can penetrate between about 6 and 20 feet (2 and 6 meters) into the crust. The colors on this map illustrate a distinct temperature gradient across the moon, with the most extreme, localized heat output in red. 

The most prominent red anomaly in the upper left (between 60 and 120 degrees west longitude) reveals subsurface temperatures 18 to 36 degrees Fahrenheit (10 to 20 degrees Celsius, or 10 to 20 Kelvin)  warmer than the surrounding area. This massive regional heat source coincides with the Zal Montes Patera complex, an area where Juno’s Stellar Reference Unit observed an active lava flow. A second major subsurface heat source is also visible near the equator, stretching from 0 to 50 degrees west longitude. Together, these distinct microwave anomalies indicate significant internal heating occurring within the upper tens of meters of Io’s crust. 

Contrasting with these intense hot spots are the yellow and green regions, which reflect temperatures more common across the moon. The yellow areas represent intermediate temperatures that naturally warm up to near -190°F (-123°C, or 150 Kelvin) as they approach the equator. Meanwhile, the green areas, primarily visible toward the higher northern latitudes, indicate the coolest subsurface temperatures, dropping to around -298°F (-183°C, or 90 Kelvin) near the pole.
