"The spacewalk primarily focused on installing protective devices on external cables and pipelines to mitigate risks posed by potential space debris collisions, enhancing the long-term safety and stability of the space station," China Aerospace Science and Technology Corporation engineer Liu Ming told state-owned news network *CCTV*, as [quoted by the *South China Morning Post*](). The news comes after a retired Earth observation satellite dubbed Resurs-P1 broke up in orbit late last month, forcing astronauts on board the International Space Station to [shelter inside their respective spacecraft](). It broke into more than 100 pieces that are now being tracked by the US Space Command. Instead of sheltering in place, crew on board China's Tiangong space station were instructed to bulk up its physical defenses — a mission that highlights the considerable risks small pieces of space debris can pose to astronauts orbiting the Earth. ## +1 Shield Astronaut Li Cong was moved into place with the help of a robotic arm, with fellow crew member Ye Guangfu handing him the necessary equipment. A third astronaut Li Guangu monitored the mission from the station's central Tianhe module. The spacewalk took 6.5 hours and went by largely without a hitch. According to the *SCMP*, the two spacewalkers even made jokes, competed to reach a designated spot, and struck poses for the camera. "Whenever the robotic arm sent me to high points, despite the glaring sunlight, I \[could not\] help but want to take a closer look," Li Cong told *CCTV*. "It’s truly moving to witness the grandeur of this project." The three astronauts have been stationed at the orbital lab since April 26, and already installed several protective devices on the station's Mengtian lab module during a May 28 spacewalk. The latest mission involved adding other protective devices to the station's Wentian lab and Tianhe core module. The ISS features [ballistic panels]() to protect it from micrometeoroids and orbital debris as well. As illustrated in the 2013 sci-fi blockbuster "Gravity," space junk can have disastrous consequences if they ever collide with a spacecraft in orbit, from tiny micrometer-sized impacts to mission-critical holes measuring larger than one centimeter, [according to the European Space Agency](). A collision with a ten-centimeter object would "likely entail a catastrophic disintegration of the target." And our planet's orbit is only [becoming more cluttered]() as time goes on, meaning space agencies will have to get creative to ensure the survival of their crews. **More on space debris:** *[Astronauts Sheltered in Escape Vehicles as Debris Menaced Space Station]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
