India's quest to build a reusable space shuttle just cleared its first major hurdle with the successful launch today of a miniature prototype. The shuttle, which is designed to place satellites into orbit, took its first test flight today when it blasted off from the Satish Dhawan Space Center in Sriharikota, an island located off the country's southeastern coast in the Bay of Bengal. After reaching a peak altitude of 40 miles this morning, the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) re-entered the atmosphere at Mach 5 (five times the speed of sound) and successfully descended to a landing spot over the Bay of Bengal, about 279 miles from where it launched, according to a statement from India's Space Research Organization (ISRO).
