Question Numbers: 81-85
Direction: Read the passage given below and answer the following questions.
Astroscale is a space sustainability company headquartered in Tokyo that is committed to creating solutions for removing potentially dangerous space junk. As space tourism missions to the ISS (International Space Station) become more prevalent, even more attention will have to be paid to orbital highways to ensure their maintenance and cleanliness. It’s more than a courtesy, it’s a matter of space safety. Even without private space tours, the prevalence of space junk and the risk of collisions have skyrocketed with the emergence of SpaceX, OneWeb, and other companies that send thousands of rockets into LEO. It is quickly becoming a safety issue—SpaceX’s huge Starlink project has made Earth’s orbit much more dangerous which is why Astroscale aerospace engineer Jonathan Rasmussen is calling for more accountability from prominent satellite companies around the life and death of satellites and intentional de-orbiting. De-orbiting refers to the discarding of defunct junk in space. “In order to mitigate space debris,” he says. “There should be some form of binding international policy where satellite operators and builders send out their satellites with a predetermined plan for the end of life, where they purposely de-orbit it with their last ounce of fuel versus letting the satellites just float around up there.” The company’s End-of-Life Services demonstration (ELSA-d) mission, launching in less than two months, seeks to exhibit the company’s ability to capably and safely find, dock with, and remove orbital debris. The ELSA-d space debris removal mission revolves around two pieces of machinery: a service vehicle (approximately 175 kg) and a smaller client vehicle (approximately 17 kg). The service vehicle is the deorbiter, which physically seeks out, latches onto, and retrieves target debris objects.
