TOKYO (Jaxa PR) — ASTROSCALE Japan Inc. (hereinafter referred to as “ASTROSCALE”) and the Japan Aerospace Exploration Agency signed a joint research agreement (“the agreement”) regarding the removal of space debris.
Under the terms of the agreement, ASTROSCALE will have access to JAXA’s technologies that examine the methods to approach and capture space debris. The technologies will facilitate ASTROSCALE’s development of ELSA-d, a technology demonstration satellite scheduled to be launched in the first half of 2019. ASTROSCALE and JAXA will also work together to validate the imagery of simulated debris obtained through the ELSA-d on-orbit mission. JAXA will not take direct part in the development, launch, or operation of ELSA-d, but will be involved in the research and development of relevant component technologies.
It is estimated that more than 750,000 pieces of space debris over a centimeter in size are currently in orbit, some of which are the result of breakups and collisions of spacecraft. As the continuously rising debris population poses an immediate threat to the orbital environment, taking countermeasures is urgently needed.
JAXA, in cooperation with universities and the private sector, will further establish the technology to eliminate space debris. Through this endeavor, JAXA hopes to protect the space environment and realize sustainable utilization of space.
NASA would be given a mandate to pioneer the development and settlement of space and a commission dominated by Congressional appointees to oversee those efforts under a bill proposed by Rep. Jim Bridenstine (R-OK).
The measure’s basic premise is that NASA’s problems stem from unstable presidential commitments to space exploration as opposed to Congress’ tendency to support expensive programs that bring funding into particular states and districts.
“Over the past twenty years, 27 NASA programs have been cancelled at a cost of over $20 billion to the taxpayer,” according to a statement on a website devoted to the measure. “Many of these have come as a result of changes in presidential administrations.
Three launches are scheduled for the week ahead, including a pair in the United States and one in India.

SINGAPORE, July 14, 2017 (ASTROSCALE PR) — ASTROSCALE PTE. LTD. (ASTROSCALE), a pioneering space company with a goal of mitigating space debris, completed a Series C round and raised $53 million in total to date. Private companies, ANA Holdings Inc. (ANA – parent company of ALL NIPPON AIRWAYS Co., Ltd.) and OSG Corporation, join recurring venture capital investors (Innovation Network Corporation of Japan, JAFCO Co., Ltd., and Mitsubishi UFJ Capital) alongside new financier aSTART Co., Ltd.
JAXA has published this Q&A interview with Michiru Nishida, a Japanese Foreign Affairs official who works on space debris debris issues.
— In light of the fact that the space debris situation is becoming more serious, what international agreements have been made, if any?
In 2007, the United Nations General Assembly adopted the Space Debris Mitigation Guidelines drafted by the Committee on the Peaceful Uses of Outer Space (COPUOS). This is a “soft law” that aims to limit the generation of new space debris. A soft law is not legally binding – member states are left to make efforts on their own initiative. The guidelines specify, among other things, that rockets and satellites should be designed to produce no debris, and that satellites in low Earth orbit should re-enter the atmosphere within 25 years of ending their mission.
JAXA has published the following Q&A interview with Mayumi Matsuura, the space agency’s space situation awareness (SSA) system project manager.
— What is the current state of space debris monitoring in Japan?
Space debris is monitored at the Kamisaibara Spaceguard Center and the Bisei Spaceguard Center, both in Okayama Prefecture. At Kamisaibara, we use radar to monitor debris in low Earth orbit (LEO) up to an altitude of approximately 2,000 km. Although the size of debris that can be monitored depends on its altitude, we can simultaneously track a total of 10 targets 1 meter or more in diameter. At Bisei, we use an optical telescope, which allows us to monitor debris in geostationary Earth orbit (GEO) at an altitude of 36,000 km.
JAXA analyzes data from these facilities to pinpoint debris orbit and position, and when this data and other inputs show that there is a possibility of debris colliding with satellites, a warning is issued to the satellite team. This is the role of the Space Tracking and Communications Center (STCC), where I work. To avoid being hit by debris, all you need to do is change your orbit, so the center prepares detailed proposals on when and how to do this. In some cases, debris is expected not to burn up on reentry into the atmosphere, but to fall back to Earth. In these situations, my job is to predict where it will reenter the atmosphere. (more…)
The Japanese space agency JAXA has published the following Q&A with Nobu Okada, founder and CEO of ASTROSCALE PTE. The company is focused on cleaning up orbital debris.
— It’s been said that you are the first private enterprise in the to attempt to clean up space debris.
Our mission is to secure long-term spaceflight safely by solving space debris issues. To achieve this, ASTROSCALE will extend its business model to a debris removing technology after gaining an understanding of the present space environment. As our first step, we investigate how much space debris exist in outer space. The size of space debris varies, and it is important to ascertain its density etc.
Engine for Growth: Analysis and Recommendations for U.S. Space Industry Competitiveness
Aerospace Industries Association May 2017 [Full Report]
Policy Recommendations for Strengthening U.S. Space Competitiveness
1. Level the Playing Field
Provide a responsive regulatory environment for commercial space activities. The list of commercial space activities is varied and growing, ranging from traditional applications such as satellite telecommunications to emerging ones like space resource utilization. At the same time, the U.S. space industry is governed by multiple federal agencies with disparate regulatory interests, including the Federal Communications Commission, the Federal Aviation Administration and Departments of State and Commerce. These agencies often suffer from funding and staffi ng shortages, a situation that creates bottlenecks in licensing processes and slows responsiveness to technological and market changes. The new Administration should work closely with Congress to ensure that the appropriate space regulatory agencies are fully resourced and staffed. (more…)
DARMSTADT, Germany (ESA PR) — With more than 750 000 pieces of dangerous debris now orbiting Earth, the urgent need for coordinated international action to ensure the long-term sustainability of spaceflight is a major finding from Europe’s largest-ever conference on space debris.

JAXA’s effort to test an electrodynamic tether (EDT) that could help clean up orbital space debris has hit a snag, Japanese media report.
The 700 meter (2,297 ft) long tether was to have deployed from the Kounotori resupply ship after it separated from the International Space Station on Jan. 27. However, JAXA says the tether, which had a mass on the end that weights about 20 kg (44 lb.), did not deploy as planned.
The agency planned to continue trying to try to deploy the tether through Saturday (today). The supply ship is scheduled to burn up in the Earth’s atmosphere on Monday.
The tether is designed to slow down a piece of debris by running an electrical current through it. The current will hasten the entry of the debris into the Earth’s atmosphere.
“JAXA plans to perform Kounotori Integrated Tether Experiments (KITE) in order to establish and demonstrate EDT technology and to obtain some EDT characteristics, such as tether deployment dynamics, and electron emission and collection in space plasma,” the space agency says on its website.
“KITE will help us identify the features and key technologies necessary to design and develop an EDT system as a method for improving space safety by removing large debris,” the website states.
A white paper outlining China’s space policy for the next five years calls for a sample return mission to the moon, a landing on the far side of Earth’s closest neighbor, and the launch of an orbiter and lander to Mars by 2020.
China will also begin constructing a permanent space station and research and development work on a heavy-lift launcher, reusable boosters and satellite servicing systems.
The nation also wants to expand international cooperation in areas that include remote sensing, space applications, lunar and planetary exploration, and human spaceflight.
