As of January 2018 an estimated 8,100 tons of space debris has accumulated in low Earth orbit consisting of spent rocket bodies, mission-related debris, and collision fragments. The vast majority of these objects are too small to detect with radar systems, but there are over 29,000 known objects larger than 10 cm. Impacts between these objects and operating missions have damaged costly equipment, required expensive collision avoidance maneuvers, and endangered the lives of astronauts on the international space station.
DENVER, April 10, 2019 (Astroscale PR) – Astroscale Holdings Inc. (“Astroscale”), the market-leader in developing a space debris removal service to secure long-term orbital sustainability, today announced the opening of a new office in Denver, Colorado (“Astroscale U.S.”), adding a strategic United States base to already established entities in Singapore, Japan and the United Kingdom. In concert with the expansion of its global presence, Astroscale has solidified its leadership team and secured an additional US $30 million in an extension of its Series D investment round. The funding extension round brings the total Series D amount to US $80 million and total capital raised to US $132 million.

Indian officials are dismissing concerns expressed by NASA Administrator Jim Bridenstine about debris in low Earth orbit from an Indian anti-satellite (ASAT) test that could threaten the International Space Station (ISS) and other spacecraft.
The Hindustan Times reports that an official from the Defence Research and Development Organisation (DRDO) as downplaying the dangers.
The DRDO chief and a spokesperson did not comment. An official of the agency, while asking not to be named, said the debris will disappear in 45 days. “The test was calibrated keeping in mind the debris issue. The world should know that debris from two Chinese tests is still floating whereas those created by the Indian test will disappear,” he added.
An Indian expert said that India conducted the anti-satellite test responsibly but agreed it could have raised risks for the ISS. “I would say India conducted the test responsibly. At 300km, the altitude is lower than that of the ISS and most of the other satellites and the debris will come back to the atmosphere of the earth eventually. That said, there is a possibility that some debris might enter the apogee of the space station; the risk of collision increases as it does with any object sent to space ,” said Rajeswari Rajagopalan, head of nuclear and space initiative, Observer Research Foundation (ORF).
Prime Minister Narendra Damodardas Modi hailed the test, saying it made India a space power.
During a NASA all-hands meeting on Monday, Bridenstine said the test created 400 pieces of debris, including 24 that went above the apogee of the International Space Station (ISS).
“That is a terrible, terrible thing, to create an event that sends debris into an apogee that goes above the International Space Station,” he said. “And that kind of activity is not compatible with the future of human spaceflight. It’s unacceptable, and NASA needs to be very clear about what its impact to us is….
“While the risk went up 44 percent, our astronauts are still safe. The International Space Station is still safe. If we need to maneuver it, we will. The probability of that, I think, is low,” Bridenstine added.
The space station has maneuvered on many occasions to avoid potential debris strikes.
Bridenstine expressed concerns that the Indian ASAT test will inspire other nations to conduct similar ones, thus increasing the debris in orbit.
Citing new satellite constellations that plan to collectively launch thousands of new satellites into Earth orbit, the Federal Communications Commission (FCC) has decided to update its regulations on space debris for the first time in 15 years.
“Proposed deployments of large satellite constellations in the intensely used LEO region, along with other satellites deployed in the LEO region, will have the potential to increase the risk of debris-generating events,” the FCC said in a notice in the Federal Register. “New satellite and deployment technologies currently in use and under development also may increase the number of potential debris-generating events, in the absence of improved debris mitigation practices.”
SURREY, UK (University of Surrey PR) — The RemoveDEBRIS satellite, one of the world’s first attempts to address the build-up of dangerous space debris, has successfully used its on-board harpoon-capture system in orbit.
The Airbus Stevenage designed harpoon featured a 1.5 metre boom deployed from the main RemoveDEBRIS spacecraft with a piece of satellite panel on the end. The harpoon was fired at 20 metres/sec to penetrate the target and demonstrate the ability of a harpoon to capture debris.
PARIS (Thales PR) — More powerful and accurate, Earth Observation satellites feature major breakthrough technologies contributing to a better understanding of our planet, our oceans, our weather conditions… in a nutshell, our global environment. Earth Observation satellites, whether using radar or optical payloads, can also be used for defense uses, in particular for applications linked to maritime security or border surveillance. Moreover, powerful telecommunications satellites can offer High Speed Internet in certain coverage zones, directly contributing to bridge the digital divide, in particular in isolated areas.
Yet that only will be possible if they can find space in that space—a place to park in orbit that will not be vulnerable to the dangers of increasing space debris.
WASHINGTON, November 15, 2018 (FCC PR) — The Federal Communications Commission today initiated a comprehensive review of its orbital debris mitigation rules. [Download proposed rules here.]
Orbital debris, also known as space debris, consists of a variety of objects, including non-functional satellites, that are orbiting the Earth. Debris can pose a risk to operations in Earth orbit, including satellites and manned spacecraft, and in some instances, pieces of debris falling back to Earth can pose a risk to persons and property on the surface of the Earth.

In recent years, several commercial companies have proposed telecommunications constellations consisting of hundreds to thousands of 100-to-300-kg class spacecraft in low Earth orbit (LEO, the region below 2000-km altitude). If deployed, such large constellations (LCs) will dramatically change the landscape of satellite operations in LEO. Fig. 1 shows the current mass distribution in LEO. The top blue histogram shows the total and the three curves below show a breakdown by object type (spacecraft, rocket bodies, or other). The mass distribution is dominated by spacecraft and upper stages (i.e., rocket bodies). The yellow bars from 1100 km to 1300 km altitudes show the notional mass distribution from 8000 150 kg LC spacecraft or, equivalently, 4000 300 kg LC spacecraft. From the large amount of mass involved, it is clear that the deployment, operations, and frequent de-orbit and replenishment of the proposed LCs could significantly contribute to the existing orbital debris problem.

PARIS (ESA PR) — The Ministers in charge of space within the 22 ESA Member States and Canada gather typically every three years to set the Agency’s strategy and policies. During these ESA Council meetings at Ministerial Level, decisions are taken on the main direction for the coming years and on the additional budget for the future. Ministers agree to start new programmes or eventually to bring them to an end. This time, the ‘space ministers’ will meet on 1–2 December in Lucerne, Switzerland.
The meeting this year will define ESA’ objectives based on the vision of a United Space in Europe in the era of Space 4.0. (more…)
HOUSTON (NanoRacks PR) — Surrey Space Centre and NanoRacks are pleased to announce the RemoveDebris mission will be deployed into low-Earth orbit from the International Space Station (ISS) using the NanoRacks Kaber Satellite Deployment System (Kaber).
Since the beginning of the space era, a huge amount of orbital debris has progressively been building up; from old rocket casings to dead satellites, there are almost 7,000 tonnes of it around the Earth. Active debris removal missions have been suggested as a way of limiting and controlling future growth by actively sending up spacecraft to capture and remove the debris from space – to date this has never been fully achieved.
TOKYO (JAXA PR) — The Japan Aerospace Exploration Agency (JAXA) established the emergency headquarters led by President Okumura and has been doing its utmost to understand the anomaly of the X-ray Astronomy Satellite ASTRO-H (“Hitomi”). We have made every effort to confirm the status of ASTRO-H and to regain its functions. Unfortunately, based on our rigorous technical investigation, we had to conclude as follows.
(1) Most of our analyses including simulations on the mechanisms of object separation, it is highly likely that both solar array paddles had broken off at their bases where they are vulnerable to rotation.
(2) Originally, we had some hopes to restore communication with ASTRO-H since we thought we received signals from ASTRO-H three times after object separation. However, we had to conclude that the received signals were not from ASTRO-H due to the differences in frequencies as a consequence of technological study.
New Electro-Optical Tracking Site to Complement Radar Tracking Systems
DENVER, Colo., and CANBERRA, Australia, Aug. 25, 2014 (Lockheed Martin/Electro Optic Systems PR) – Under a new strategic cooperation agreement, Lockheed Martin [NYSE: LMT] and Electro Optic Systems Pty Ltd are developing a new space object tracking site in Western Australia that will paint a more detailed picture of space debris for both government and commercial customers.
