重型火箭在2004年进行首次发射,它可以将24吨重的负载发送到低地球轨道,也能将用于通讯卫星的11吨重的载荷送入地球同步轨道。
The rocket made its first flight in 2004 and is capable of launching payloads of up to 24 tons into low-Earth orbit and 11 tons toward the geosynchronous orbits used by communications satellites.
该公司称这种火箭可以将发射费用降低到大约2000美元每公斤,这大概是使用航天飞机将负载物送入轨道的费用的十分之一。
It says the rocket should reduce launch costs to about two thousand dollars a kilogram. That is about one-tenth the cost of carrying loads into orbit on a space shuttle.
