SpaceX has over 1000 Starlink satellites in orbit. However, the number is just part of the large constellation the firm anticipates launching. SpaceX had asked permission from the FCC to deploy 12,000 satellites. There would be about 42,000 and more satellites orbiting in the coming few decades. There is always a possibility that those satellites might collide with other spaceships in orbit, increasing the high risks of accidents occurring in space. To avoid collision and dangerous accidents, NASA and SpaceX had to sign a deal and reach a way forward for their future launches.
Currently, NASA is working with other companies that help deploy objects into orbit. Such entities use the standard Conjunction Assessment process to determine the possibility of a collision between two things in the space. The deal with SpaceX will enable active partnership in the forthcoming years to reduce energetic collisions between satellites from taking place.
NASA agreed to share its data with SpaceX concerning its future projects and seizing to move any object in case of a possible collision. The firm will use the data provided to program all Starlink’s automated avoidance measures to prevent the satellites from taking a mysterious activity. Additionally, SpaceX requires that deployed Starlink’s satellites are 5 kilometers above or below the points of the International Space Station’s orbit.
Last year September, a small piece of shrapnel from a Japanese H-2A rocket dashed towards the ISS together with its crew at a speed of 17,500 per hour. One hour before the collision took place, flight controllers on earth controlled the spacecraft’s shafts to get it out of the way.
ESA used DISCOS (Database and Information System Characterizing Objects in Space) to examine the possible danger of collisions between satellites. If the collision’s risk attains a given threshold, an alarm is raised, and those who control the missions order the spacecraft causing the possible crash to take any evasive action.
Currently, near-Earth satellites always have the fuel allowance to help them take evasive maneuvers during the predestined period of the spaceship. In 1993, a first servicing mission unveiled a hole of over 1cm in diameter in a high-gain antenna fixed on the Hubble Space Telescope. The space debris object penetrated the antenna dish completely; however, the structure was still functioning.
In July 1996, France’s Cerise military exploration satellite was hit and damaged severely by a cataloged Arian upper-stage explosive piece. Windows of Space Shuttle have been fitted 80 times because of the impact caused by sub-millimeter objects. However, no one is certain enough if there would not be any collisions in the coming decade. Steps towards mitigating satellite collisions are underway.
