PARIS (ESA PR) — The Moon is set to gain one more crater. A leftover SpaceX Falcon 9 upper stage will impact the lunar surface in early March, marking the first time that a human-made debris item unintentionally reaches our natural satellite.
In 2015 the Falcon 9 placed NOAA’s DSCOVR climate observatory around the L1 Lagrange point, one of five such gravitationally-stable points between Earth and the Sun. Having reached L1, around 1.5 million km from Earth, the mission’s upper stage ended up pointed away from Earth into interplanetary space.
Space debris is a major threat to the satellite services we rely on
13 projects involve industry and academia across the UK
SWINDON, UK (UK Space Agency PR) — The UK Space Agency is providing £1.7 million [US $2.3 million] for new projects to support sustainable space operations, Science Minister George Freeman announced today.
The 13 new projects will help track and remove dangerous debris in space. They include an AI-based tool which can take autonomous action to avoid a collision and another which will see multiple small spacecraft fired at debris before taking it into the atmosphere to dispose of it.
PARIS (ESA PR) — In 2021 so far, some 2467 new objects large enough to be tracked have been added to world catalogues of orbital objects, out of which 1493 are new satellites and the rest are debris. While new objects are added, others are dragged down to Earth by the atmosphere where they safely burn up, resulting in a net increase of at least 1387 trackable objects between 2020 and 2021.
In addition, an estimated 1500 new objects – an increase of about 5% with respect to the total population – were added just this week, meaning the risk to missions must be reassessed.
SWINDON, UK (UK Space Agency PR) — The UK Space Agency is today announcing a range of different initiatives aimed at supporting safe and sustainable space operations.
From developing our space tracking capabilities and promoting international efforts in space sustainability, to finding novel ways of removing space debris – the UK is leading the way to ensure the Earth’s orbit can continue to be used now and in the future.
CORNWALL, UK, 13 June 2021 (UK Space Agency PR) — Today at the G7 Leaders’ Summit in Carbis Bay, Cornwall, delegates from Canada, France, Germany, Italy, Japan, the USA, the UK and the EU pledged to take action to tackle the growing hazard of space debris as our planet’s orbit becomes increasingly crowded.
One of the biggest global challenges facing the space sector is orbital congestion and space debris. There are currently an estimated 900,000 pieces of space debris including old satellites, spent rocket bodies and even tools dropped by astronauts orbiting Earth. Space debris could stay in orbit for hundreds of years and present a real danger to the rapidly increasing number of new satellites being launched each year.
Maintaining safety of operations and maximising scientific return are key concerns as satellites increase in number and complexity
Artificial intelligence offers promising solutions to modern spaceflight challenges
ESA and Germany’s DFKI institute have launched a new lab ‘ESA_Lab@DFKI’ for artificial intelligence research
KAISERLAUTERN, Germany (ESA PR) — It’s 4 October 1957, and the Soviet Union has just lofted humanity’s first satellite – Sputnik 1 – into the pristine orbital environment around Earth, marking the start of the Space Age.
Throughout 1960s and 70s, launches quickly increase, as the USA, Soviet Union and other countries race for space, discovering and utilising the immense value of the ‘orbital pathways’ above us – a precious, limited natural resource.
PARIS (ESA PR) — Swirling fragments of past space endeavours are trapped in orbit around Earth, threatening our future in space. Over time, the number, mass and area of these debris objects grows steadily, boosting the risk to functioning satellites.
ESA’s Space Debris Office constantly monitors this ever-evolving debris situation, and every year publishes a report on the current state of the debris environment.
