Part 5/7:
To achieve this meticulous controlled descent, NASA has been allocated a budget of $180 million to develop a specialized space tug. This innovative spacecraft will play a crucial role in guiding the ISS to its final resting stop. Historically, the deorbiting strategy relied on Russia's robotic Progress cargo vehicles. However, with the introduction of this space tug, NASA aims to establish its own means of safely transiting the ISS from orbit, thereby reducing dependency on external entities.
