NASA has unveiled a $28 billion plan to put the first woman and another man on the moon in 2024.
The mission would put the first people on the moon's surface since 1972.
"With bipartisan support from Congress, our 21st century push to the Moon is well within America's reach," said NASA Administrator Jim Bridenstine in a statement. "As we build up a sustainable presence, we're also building momentum toward those first human steps on the Red Planet."
Bridenstine said the mission, part of NASA's Artemis plan, would be for "scientific discovery, economic benefits, and inspiration for a new generation of explorers."
The $28 billion plan hinges on acquiring $3.2 billion for a human landing system. The House of Representatives have approved $600 million already.
"I want to be clear, we are exceptionally grateful to the House of Representatives that, in a bipartisan way, they have determined that funding a human landing system is important – that's what that $600 million represents," Bridenstine said. "It is also true that we are asking for the full $3.2 billion."
The agency plans to launch two test flights, one unmanned in 2021 and another with a crew in 2023.
