Video: 00:01:43 An essential part of ESA’s Space Safety programme is dedicated to getting and keeping Earth’s orbits clean from space debris. In the long run, the Agency aspires to stimulate a true circular economy in space, minimising the impact of spaceflight on Earth and its resources where possible. As part of ESA’s Zero Debris approach, new ESA missions will be designed for safe operations and disposal to stop the creation of new debris by 2030.
ESA has now taken another important step on the road towards sustainability in space with its first in-orbit servicing mission RISE, planned for launch in 2029.
RISE is a commercial in-orbit servicing mission that will demonstrate that it can safely rendezvous and dock to a geostationary client satellite, extending the life of geostationary satellites that need support with attitude and orbit control, but are otherwise in working order.
After verifying that it meets all the performance standards in a first demonstration, prime contractor, operator and co-founder D-Orbit will start commercial life extension services for geostationary satellites.
ESA’s RISE mission marks a promising step towards enhancing in-orbit services and technologies, such as refuelling, refurbishment and assembling – all essential elements for creating a circular economy in space.

This NASA Hubble Space Telescope image features a dense and dazzling array of blazing stars that form globular cluster ESO 591-12.NASA, ESA, and D. Massari (INAF — Osservatorio di Astrofisica e Scienza dello Spazio); Processing: Gladys Kober (NASA/Catholic University of America) A previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular clusters like this one, called ESO 591-12 or Palomar 8, are spherical collections of tens of thousands to millions of stars tightly bound together by gravity. Globular clusters generally form early in the galaxies’ histories in regions rich in gas and dust. Since the stars form from the same cloud of gas as it collapses, they typically hover around the same age. Strewn across this image of ESO 591-12 are a number of red and blue stars. The colors indicate their temperatures; red stars are cooler, while the blue stars are hotter.
Hubble captured the data used to create this image of ESO 591-12 as part of a study intended to resolve individual stars of the entire globular cluster system of the Milky Way. Hubble revolutionized the study of globular clusters since earthbound telescopes are unable to distinguish individual stars in the compact clusters. The study is part of the Hubble Missing Globular Clusters Survey, which targets 34 confirmed Milky Way globular clusters that Hubble has yet to observe.
The program aims to provide complete observations of ages and distances for all of the Milky Way’s globular clusters and investigate fundamental properties of still-unexplored clusters in the galactic bulge or halo. The observations will provide key information on the early stages of our galaxy, when globular clusters formed.

4 Min Read Future Engineers Shine at NASA’s 2025 Lunabotics Robotics Competition
And the winner is… the University of Utah in Salt Lake City. The Utah Student Robotics Club won the grand prize Artemis Award on May 22 for NASA’s 2025 Lunabotics Challenge held at The Astronauts Memorial Foundation’s Center for Space Education at the Kennedy Space Center Visitor Complex in Florida.
“Win was our motto for the whole year,” said Brycen Chaney, University of Utah, president of student robotics. “We had a mission objective to take our team and competition a step further, but win was right up front of our minds.”
Lunabotics is an annual challenge where students design and build an autonomous and remote-controlled robot to navigate the lunar surface in support of the Artemis campaign. The students from the University of Utah used their robot to excavate simulated regolith, the loose, fragmented material on the Moon’s surface, as well as built a berm. The students, who competed against 37 other teams, won grand prize for the first time during the Lunabotics Challenge.
“During the 16th annual Lunabotics University Challenge the teams continued to raise the bar on excavating, transporting, and depositing lunar regolith simulant with clever remotely controlled robots,” said Robert Mueller, senior technologist at NASA Kennedy for Advanced Products Development in the agency’s Exploration Research and Technology Programs Directorate, and lead judge and co-founder of the original Lunabotics robotic mining challenge. “New designs were revealed, and each team had a unique design and operations approach.”
Students from University of Illinois Chicago receive first place for the Robotic Construction Award during the 2025 Lunabotics Challenge.NASA/Isaac Watson Other teams were recognized for their achievements: The University of Illinois Chicago placed first for the Robotic Construction Award. “It’s a total team effort that made this work,” said Elijah Wilkinson, senior and team captain at the University of Illinois Chicago. “Our team has worked long and hard on this. We have people who designed the robot, people who programmed the robot, people who wrote papers, people who wired the robot; teamwork is really what made it happen.”
The University of Utah won second and the University of Alabama in Tuscaloosa came in third place, respectively. The award recognizes the teams that score the highest points during the berm-building operations in the Artemis Arena. Teams are evaluated based on their robot’s ability to construct berms using excavated regolith simulant, demonstrating effective lunar surface construction techniques.

Students from Purdue University in Lafayette, Indiana received the Caterpillar Autonomy Award during the 2025 Lunabotics Challenge.
NASA/Isaac Watson Students from Purdue University in Lafayette, Indiana received the Caterpillar Autonomy Award for their work. The University of Alabama placed second, followed by the University of Akron in Ohio. This award honors teams that successfully complete competition activities autonomously. It emphasizes the development and implementation of autonomous control systems in lunar robotics, reflecting real-world applications in remote and automated operations.
An Artemis I flag flown during the Nov. 16, 2022, mission was presented to the University of Illinois Chicago, as well as the University of Virginia in Charlottesville as part of the Innovation Award. The recognition is given to teams for their original ideas, creating efficiency, effective results, and solving a problem.
Dr. Eric Meloche from the College of DuPage in Glen Ellyn, Illinois, and Jennifer Erickson, professor from the Colorado School of Mines in Golden each received an Artemis Educator Award, a recognition for educators, faculty, or mentors for their time and effort inspiring students.
The University of Utah received the Effective Use of Communications Power Award and the University of Virginia the agency’s Center for Lunar and Asteroid Surface Science Award.

NASA/Isaac Watson Students from the Colorado School of Mines placed first receiving a Systems Engineering Award. University of Virginia in Charlottesville and the College of DuPage in Glen Ellyn, Illinois, came in second and third places.
This is truly a win-win situation. The students get this amazing experience of designing, building, and testing their robots and then competing here at NASA in a lunar-like scenario while NASA gets the opportunity to study all of these different robot designs as they operate in simulated lunar soil. Lunabotics gives everyone involved new technical knowledge along with some pretty great experience.”
