ESA's potential space garbage collector nets itself a drone

ESA has provided a preview of its plan to net space debris by unveiling a prototype net gun designed to envelope and capture tumbling dead satellites. Wojtek Gołebiowski of Poland's SKA Polska, which is developing the gun under a contract with the space agency, used a small version to target and take down a low-flying drone at the Industry Days event for ESA's Clean Space initiative.Read More

Space station crew takes shelter as debris passes

For the fourth time in history, the crew of the International Space Station (ISS) had to temporarily take shelter in their "lifeboat" as a piece of an old weather satellite made its closest approach today at 8:01 am EDT. As a precaution, the three men of Expedition 44 sealed hatches and porthole covers before retreating to the Soyuz TMA-16M spacecraft docked with the station.Read More

ESA's mission to de-clutter low-Earth orbit takes a step forward

ESA's mission to mitigate the environmental impacts on low-Earth orbit from mankind's relentless march into space has entered a new phase, ahead of its make-or-break review before the ESA's Council of Ministers in December 2016. The e.Deorbit program would launch multiple debris-seeking probes into orbit each year, tasked with the removal of defunct satellites and other potentially hazardous man-made objects from low-Earth orbit.Read More

Lasers could be used to zap orbital debris

Orbital debris is increasingly becoming a hazard to satellites and other spacecraft, which is why various groups have proposed concepts such as gas clouds, nets and sails for collecting it. While those approaches could capture larger objects, the problem of smaller pieces of debris – which whiz around the Earth like bullets – would remain. That's why an international group of scientists is developing a system that could shoot those bits down with a laser. Read More

ESA tests the potential of grabbing derelict satellites using a simple net

The ESA has been testing the possibility of using one of mankind's earliest inventions to cope with one of its newest challenges, by testing a concept that would allow satellites to net and de-orbit space debris in a safe and controlled manner. Space debris is an ever-increasing problem, and agencies around the world are starting to take steps to preserve the low-Earth orbit environment vital for a sustainable space industry.Read More

Construction begins on Space Fence radar system

Ground was broken at the future six-acre (2.4-hectare) site of the new Space Fence radar system in a special ceremony last month on Kwajalein Atoll in the Marshall Islands. The ceremony marked the official start of construction of the system that will replace the Air Force Space Surveillance System (AFSSS) in tracking objects in orbit, including commercial and military satellites and debris from collisions.Read More

US satellite explodes and ESA assesses risk

A US Air Force weather satellite exploded in Earth orbit on February 3, scattering debris along its path. In a report by Space.com, Air Force and space officials indicated the breakup of Defense Meteorological Satellite Program Flight 13 (DMSP-F13) was due to a malfunction of its battery system rather than a collision with a foreign body. Meanwhile, The European Space Agency (ESA) has released an assessment of the hazard posed by the debris.Read More

ESA to host workshop aimed at cleaning up low-Earth orbit

Key orbits frequented by GPS and communications satellites are becoming more and more hazardous, as man-made debris presents an increasingly palpable danger to the valuable assets orbiting at heights of around 2,000 km (1,243 miles) above the Earth. That' s why the European Space Agency (ESA) is hosting an international workshop geared towards cleaning up low-Earth orbit, with a focus on how to make the space industry more sustainable.

ESA sets its sights on harpooning space debris

In 2021, as part of its Clean Space Initiative, ESA plans to launch the e.DeOrbit mission. The aim of this mission is to clean up the important polar orbits between altitudes of 800 to 1,000 km (500 to 625 mil) that face the prospect of becoming unusable due to the increasing buildup of space debris. The ESA has now announced plans to examine the potential for the mission to use space harpoons to capture large items, such as derelict satellites and the upper stages of rockets.Read More
