    An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform. SpaceX developed these vessels to recover the first stage (also called the booster) of its launch vehicles.

    The most fuel-efficient means to move from one circular orbit to another is with a Hohmann transfer orbit: the spacecraft begins in a roughly circular orbit around the Sun. A short period of thrust in the direction of motion accelerates or decelerates the spacecraft into an elliptical orbit around the Sun which is tangential to its previous ...

    A single laser facility on the ground can in theory launch single-stage vehicles into low or high earth orbit. The payload can be 20% or 30% of the vehicle take-off weight. It is far more economical in the use of mass and energy than chemical propulsion, and it is far more flexible in putting identical vehicles into a variety of orbits."

    It is a scaled down prototype of an eventual two-stage-to-orbit (TSTO) reusable launch vehicle. In January 2012, the design of ISRO's reusable launch vehicle was approved by the National Review Committee and clearance was granted to build the vehicle. The vehicle was named 'Reusable Launch Vehicle-Technology Demonstrator' (RLV-TD). [19]
