ULA To Unveil Atlas 5 Details at Space Symposium

摘要

U.S. government launch services provider United Launch Alliance has completed the conceptual trade studies for its revamped Atlas 5 rocket and plans to unveil details in April, Tory Bruno, the company's president and chief executive, said Jan. 22. "Come to Space Symposium," Bruno said in a tweet Jan. 12. "I will be revealing our new system." Bruno followed up on the tweet Jan. 22, adding, "The top level trades are done." ULA is working with Blue Origin, the secretive rocket-making venture led by Amazon.com founder Jeff Bezos, to develop a new engine, dubbed the BE-4. That engine would replace the Russian-made RD-180 that powers the first stage of ULA's Atlas 5 rocket.
