2018-03-13来源:和谐英语

AZUZ: The most powerful rocket in the world taking off. Falcon Heavy is the name of the SpaceX rocket. After a couple of delays, it blasted off the ground at about 3:45 p.m. yesterday at Kennedy Space Center in Florida. SpaceX, which has received billions in grants from NASA estimates that each launch of a Falcon Heavy rocket caused about $90 million. But that's reportedly hundreds of millions cheaper than the world second most powerful rocket.

As a way to decrease the high cost of spaceflight, Falcon Heavy's three rocket boosters are designed to land upright back on earth to be reused.
At least two of them did that yesterday at Kennedy Space Center. The third was supposed to land at a platform at sea but we didn't know immediately if that return was a success.
