NASA's big new missile will not be ready for release next year, the US Space Agency's deputy prime minister said this week. scheduled launch date in June 2020
NASA's missed missile is called "Space Starter System" or SLS.
Brixtinna added that NASA will need two private missiles to take over SLS's job of launching the Orion capsule and top stage . Before going to the Moon, Orion must climb up the orbit around the Earth.
"This is 2019," said Senator Roger Wicker, chairman of the committee, to Bridgetin. "I'd like to keep us on schedule ."
The first test flight was scheduled for this year. "I want to be clear: NASA has a history that it does not meet starting dates, and I'm trying to change that," Bridentalina said.
NASA is looking for a sustainable lunar program. In the past, Apollo's moon landings were direct trips from and back to Earth. The goal now is to have a base with astronauts near the moon
Orion will not carry a crew and will not land on the Moon. Instead, Orion would have approached the Moon before traveling beyond it.
NASA's statement says Orion "will travel from Earth 280,000 miles [450,000 kilometers] a thousand miles from the moon for about three weeks of mission."
The statement adds: More than any ship for astronauts did without dock at a space station, and come back home faster and hotter than ever. "If private missiles for Mission 2020 are to be used, SLS will be commissioned for NASA's second mission to study by 2023.
