TALON: Token-Aligned Lightweight Adapters for 6-DoF Spacecraft Pose Estimation
new Abstract: Monocular 6-DoF spacecraft pose estimation methods predominantly process individual frames, discarding the temporal information present in an image sequence acquired during spacecraft manoeuvres. Few temporal approaches require full backbone fine-tuning or auxiliary optical flow networks, risking catastrophic forgetting or increasing computational cost, respectively. We propose TALON (Token-Aligned Lightweight adapters for Orbital Navigation): spatiotemporal 3D adapters...
Areostationary Satellite Station Keeping Via a Natural Motion Trajectory and Predictive Control
arXiv:2603.00781v2 Announce Type: replace Abstract: Areostationary Mars orbit (AMO) satellites will play an important role in future expeditions to the Martian surface due to their strength as navigation and communication satellites. Perturbative forces experienced by an AMOR satellite will cause it to drift from its nominal orbit, necessitating station keeping. This note presents a novel approach to AMO station keeping that bridges the gap seen in prior predictive control methods between...
NASA's Psyche spacecraft returns unfamiliar views of a familiar world
Not quite halfway through a six-year sojourn through the Solar System, a NASA spacecraft used a close encounter with Mars last week as a dress rehearsal for its arrival at the Solar System's largest metal asteroid in 2029. The Psyche mission launched more than two-and-a-half years ago, in October 2023, from Kennedy Space Center, Florida, to kick off a journey of some 2.2 billion miles (3.6 billion km) to reach its unexplored namesake, the asteroid Psyche. The robotic research mission got an...

From Agni 5 to Akash & hypersonics: Decoding India's homegrown arsenal & defence shield
The ongoing conflicts in Ukraine, on the borders of Israel and in the Persian Gulf have underscored the importance of indigenous defence technologies and a domestic industry to back innovation. India has been steadily working to become self-reliant in defence manufacturing. The country is now on a razor’s edge—designing, developing, and deploying homegrown defence technologies.
Blue Origin explosion ‘huge setback for everyone in space community’, ESA chief says
The European Space Agency’s (ESA) chief told Euronews that the explosion of a Blue Origin New Glenn rocket, which plays a crucial role in NASA’s Artemis missions to return to the Moon, will cause significant delays. ESA’s Director General, Josef Aschbacher, was “saddened” and “concerned” by the images showing the explosion of a Blue Origin New Glenn rocket during an engine test at a Florida launch pad last week, saying the damage was “quite big.” Amazon’s Jeff Bezos, who founded the space...
