Certainly, here is a summary of the state-of-the-art in the low-orbit space debris problem, of 2024, in bullet points:

• Increasing Risk with Constellations: The launch of multi-satellite constellations into low-Earth orbit (LEO contributes significantly to the density of objects in space, elevating the probability of collisions and the generation of further debris.

ESA's Policy and Requirements Update: The European Space Agency implemented updated policies and requirements in November 2023 aimed at reducing the amount of space debris generated from their activities, suggesting a move towards more responsible space operations.

• Orbital Debris Removal Legislation: The U.S. progressed a bill directing NASA to support missions focused on the removal of orbital debris and to assist in creating improved tracking systems for space debris.

• Debris Mitigation Strategies: There's an emphasis on limiting the time spent by objects in orbit to reduce collision risks, aligning with policies like the "25-year Deorbit rule" which encourages satellite operators to ensure their spacecraft deorbit within 25 years after the end of their mission.

• Debris Analysis for Future Mitigation: Research includes analyzing space junk that re-enters Earth's atmosphere to design spacecraft and rockets that disintegrate more completely upon re-entry, minimizing the generation of debris.

• DebriSat Project: project aimed at designing and fabricating modern spacecraft to meet the posed by space debris; it underscores the global efforts in developing technologies to mitigate.

• Orbital Space Limitations: Active satellites and future launches are endangered by non-functional debris moving rapidly in LEO, indicating a need for effective space traffic management.

• Public Awareness and Governance: Increased public discourse on the risk posed by space debris, reflecting a growing awareness of the sustainability challenges in Earth's orbit and potential governance measures.

These points reflect the combined efforts of global space agencies, governments, researchers to tackle the space debris issue from policy, operational, and technological perspectives.
