In 2022 NASA’s DART spacecraft made history, and changed the Solar System forever, by impacting the Dimorphos asteroid and measurably shifting its orbit around the larger Didymos asteroid. In the process a plume of debris was thrown out into space.
The latest modelling, available on the preprint server arXiv and accepted for publication in the September volume of The Planetary Science Journal, shows how small meteoroids from that debris could eventually reach both Mars and Earth – potentially in an observable (although quite safe) manner.

Image: ESA’s Metal 3D Printer has produced the first metal part ever created in space.
The technology demonstrator, built by Airbus and its partners, was launched to the International Space Station at the start of this year, where ESA astronaut Andreas Mogensen installed the payload in the European Drawer Rack of ESA’s Columbus module. In August, the printer successfully printed the first 3D metal shape in space.
This product, along with three others planned during the rest of the experiment, will return to Earth for quality analysis: two of the samples will go to ESA’s technical heart in the Netherlands (ESTEC), another will go to ESA’s astronaut training centre in Cologne (EAC) for use in the LUNA facility, and the fourth will go to the Technical University of Denmark (DTU).
As exploration of the Moon and Mars will increase mission duration and distance from Earth, resupplying spacecraft will be more challenging. Additive manufacturing in space will give autonomy for the mission and its crew, providing a solution to manufacture needed parts, to repair equipment or construct dedicated tools, on demand during the mission, rather than relying on resupplies and redundancies.
ESA’s technology demonstrator is the first to successfully print a metal component in microgravity conditions. In the past, the International Space Station has hosted plastic 3D printers.

Credit: NASA NASA has awarded the Center, Operations Maintenance, and Engineering II contract to Jacobs Technology Inc. of Tullahoma, Tennessee, to support operations at the agency’s Langley Research Center in Hampton, Virginia.
The contract is a cost-plus-fixed-fee indefinite-delivery/indefinite-quantity contract with a maximum potential value of $973.7 million. Following a phase-in period that starts Tuesday, Oct. 1 and runs to Dec. 31, the contract will have a base period of 15 months followed by five optional periods that could extend the contract to the end of 2035.
Under this contract, Jacobs Technology will assist in crucial research operations, engineering, and maintenance services at NASA Langley to help the center continue its work to solve the mysteries of our home planet, solar system, and beyond. The firm also will provide institutional and research operations support, maintenance and engineering for the center’s facilities, and central utilities operations, among other services.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Two robotic arms wrapped in gold material sitting on top of a black and silver box.Naval Research Laboratory NASA and the Defense Advanced Research Projects Agency (DARPA) have signed an interagency agreement to collaborate on a satellite servicing demonstration in geosynchronous Earth orbit, where hundreds of satellites provide communications, meteorological, national security, and other vital functions.
Under this agreement, NASA will provide subject matter expertise to DARPA’s Robotic Servicing of Geosynchronous Satellites (RSGS) program to help complete the technology development, integration, testing, and demonstration. The RSGS servicing spacecraft will advance in-orbit satellite inspection, repair, and upgrade capabilities.
NASA is excited to support our long-term partner and advance important technologies poised to benefit commercial, civil, and national objectives. Together, we will make meaningful, long-lasting contributions to the nation’s in-space servicing, assembly, and manufacturing (ISAM) capabilities.
Pam Melroy
NASA Deputy Administrator
NASA will use expertise from the agency’s On-orbit Servicing, Assembly, and Manufacturing 1 project and other relevant efforts to provide hands-on support to RSGS in the areas of space robotics, systems engineering, spacecraft subsystems, integration and testing, operator training, and spaceflight operations. NASA’s involvement in RSGS will continue advancing the agency’s understanding of and experience with complex ISAM systems.
DARPA will continue to lead the RSGS program, which has already achieved several important milestones, including the completion of two dexterous robotic arms designed for inspection and service that have been stress-tested for an on-orbit environment and the integration of those arms with their associated electronics, tools, and ancillary hardware to produce the fully integrated robotic payload.
