Overview:
Twelve nations have signed the Zero Debris Charter at the ESA/EU Space Council recently, solidifying their commitment to the long-term sustainability of human activities in Earth orbit.
About Zero Debris Charter:
- It is an initiative of the European Space Agency (ESA) unveiled at the ESA Space Summit in Seville meeting in November 2023.
- The Charter comes after ESA Member States encouraged the Agency to implement “a Zero Debris approach for its missions and to encourage partners and other actors to pursue similar paths”.
- It is the first initiative of its kind to bring together the largest array and variety of space actors around the world with the joint goal of creating no more debris by 2030 and making possible the long-term sustainability of space activities.
- It aims to combine far-reaching guiding principles and highly ambitious yet realistic technical targets on which to build an ambitious Zero Debris roadmap, driving global space debris mitigation and remediation efforts.
- The charter is a non-legally binding agreement, but it fosters a community of proactive actors working collectively towards jointly defined targets for 2030.
- The charter sets out a number of targets, including that a mission’s probability of generating space debrisshould remain below 1 in 1,000 per object.
- It also sets a target of 99% success for post-mission disposal, including through external means when necessary.
- It encourages transparent information sharing and space traffic coordination.
- To implement the Charter, the ESA will focus on developing ground-breaking technologies for satellite end-of-life disposal, in-orbit servicing, and active debris removal.
- In addition, ESA will work hand-in-hand with institutions in charge of regulatory aspects.
Q1: What is Space Debris?
Space debris, or more colloquially known as space junk, is considered to be any human-made object in orbit not serving a useful purpose and typically is a result of space vehicles no longer in service. The objects that fit this classification greatly range in size, from old spacecraft and the rocket stages that launched them to micro-debris like flecks of paint. Much of the debris is in low Earth orbit, within 2,000 km (1,200 miles) of Earth’s surface, though some debris can be found in geostationary orbit 35,786 km (22,236 miles) above the Equator.
