A US B-52 bomber has been given a
new role -launching satellites
Recently, a modified B-52 dropped
rocket carrying a Brazilian satellite
an altitude of about 12.8 km. Five
seconds later, the rocket motors fir
sending the 150-kg satellite into a
515-km orbit above the earth.
Orbital Sciences of Fairfax Virginia, makers of the Pegasus rocket, which sent the satellite into orbit says a smaller rocket can be used for heavier payloads provided the launch site is 13 km above the earth.
The whole operation cost US $13.5 million, barely one-third the cost of a traditional launch.
