What's Happening?
Astroscale, a Japanese space-sustainability company, has announced a mission named In-situ Space Situational Awareness-Japan 1 (ISSA-J1) set for launch in 2027. The mission aims to inspect two retired Japanese satellites, the Advanced Land Observing Satellite
(ALOS) and the Advanced Earth Observing Satellite-II (ADEOS-II). The ISSA-J1 spacecraft, weighing 1,430 pounds, will use thrusters and imaging systems to conduct detailed visual inspections of these satellites. ALOS, launched in 2006, lost power in 2011 but remains in orbit, while ADEOS-II, launched in 2002, ended its mission due to a solar panel failure. This mission follows the success of Astroscale's previous Active Debris Removal by Astroscale-Japan (ADRAS-J) mission.
Why It's Important?
The ISSA-J1 mission represents a significant step in space sustainability efforts, as it will demonstrate the ability to inspect multiple defunct satellites in different orbits. This capability is crucial for understanding satellite conditions and preparing for future servicing, which can help mitigate space debris issues. The mission supports the development of technologies that enhance space situational awareness and in-orbit servicing capabilities, which are vital for maintaining the safety and sustainability of space operations. By advancing these technologies, Astroscale contributes to the broader goal of ensuring long-term access to space for future generations.
What's Next?
Following the ISSA-J1 mission, Astroscale aims to further develop its capabilities in space debris management and satellite servicing. The success of this mission could lead to more comprehensive strategies for dealing with space debris, potentially involving collaborations with international space agencies and private companies. The insights gained from the inspections could inform future missions and policies aimed at reducing space debris and enhancing the longevity of satellites. Additionally, the mission may pave the way for more advanced in-orbit servicing missions, contributing to the establishment of a sustainable space environment.
