What is NASA doing about the problem of space junk?

NASA is actively addressing the issue of space junk through various initiatives aimed at tracking and mitigating debris in Earth's orbit. They employ advanced tracking systems to monitor space debris and predict potential collisions with operational satellites. Additionally, NASA collaborates with international agencies and private companies to develop technologies for debris removal, such as robotic arms and nets, and promotes guidelines for responsible satellite design and end-of-life disposal to minimize future debris generation.
