NASA's ambitious plans for a deorbiting 'space tug' and Biden's budget proposal for NASA and Great Lakes Authority.

NASA's proposed budget for 2024 includes $180 million for developing a space tug to deorbit the International Space Station (ISS) by the end of 2030. The agency plans to call upon the private sector to come up with a concept to lower the orbit of the ISS so that it can reenter and burn up through Earth’s atmosphere. The budget also includes funding for the Artemis lunar program, maintaining a presence in low Earth orbit, and launching samples from the surface of Mars as early as 2030. The total cost of the space tug is estimated to be around $1 billion.
