India and the U.S. have signed a bilateral Logistics Exchange Memorandum of Agreement (LEMOA) by which both nations can use each other’s land, air and naval bases for repair and resupply.

India has successfully tested its indigenously developed supersonic combustion ramjet (scramjet) engine, which engineers hope could one day allow a tenfold reduction in the cost of space launch.

The scramjet propulsion experiment will be carried by the RH-560 two-stage sounding rocket launched from Sriharikota spaceport in south India on Aug. 28.
