Current Context: The United States’ Federal Aviation Administration (FAA) has developed ‘Space Data Integrator (SDI)’ which is a new tool.

• The SDI will help to track rocket launches and space vehicles returning to the Earth in a more accurate manner.
• It will replace a system in which most part of the work of giving telemetry data about Space vehicles to air traffic control managers is done manually.
• The SDI will automate the near-instant delivery of data about space vehicles flight paths to the USA ATC System.
• The tool went through the trial on 30th June 2021 for the launch of SpaceX’s Transporter 2. It will soon be used again with the pending return of a SpaceX cargo ship from the International Space Station.
