NASA Administrator Jim Bridenstine said that the full $28 billion is needed for the Artemis moon program, designed to return astronauts to the moon by 2024.

The space agency published the Artemis Plan, which will see the first woman land on the lunar surface, as well as the next man. To date, only 12 people, all Americans, have landed on the moon.

“With bipartisan support from Congress, our 21st century push to the Moon is well within America’s reach,” Bridenstine said in a statement. “As we’ve solidified more of our exploration plans in recent months, we’ve continued to refine our budget and architecture. We’re going back to the Moon for scientific discovery, economic benefits.

"As we build up a sustainable presence, we’re also building momentum toward those first human steps on the Red Planet,” he added.

NASA HAS A PLAN FOR YEARLY ARTEMIS MOON FLIGHTS THROUGH 2030. THE FIRST ONE COULD FLY IN 2021.

Of the $28 billion NASA is asking for through fiscal 2025 for the "phase 1" part of the program, $7.6 billion is designated for the Space Launch System rockets. Some $16.2 billion is for the "initial human landing system," which includes developing, testing and launching the new lunar landers.

Some $518 million is budgeted for lunar suits; $552 million is for "surface logistics"; $1.2 billion is budgeted for exploration technologies and $1.9 billion is for the Lunar Discovery and Exploration Program, described as a key component of NASA’s Exploration Strategy that includes the "establishment of commercial contracts for lunar landing transportation services."

"Our work to catalyze the U.S. space economy with public-private partnerships has made it possible to accomplish more than ever before," Bridenstine wrote in the introduction of the plan. "The budget we need to achieve everything laid out in this plan represents bipartisan support from the Congress."

"Following a successful hot fire test, the core stage will be shipped to the agency’s Kennedy Space Center in Florida for integration with the spacecraft," the space agency wrote in the post. "NASA will launch an SLS and an Orion together on two flight tests around the Moon to check performance, life support, and communication capabilities. The first mission – known as Artemis I – is on track for 2021 without astronauts, and Artemis II will fly with crew in 2023."

Artemis III, happening in 2024, will be the mission to return to the moon.

In January, Congressman Kendra Horn, D-Okla., proposed a bill to urge NASA to consider a 2028 deadline for putting U.S. astronauts back on the moon in order to boost the space agency’s long-term plans for crewed Mars exploration.

NASA’s Artemis program aims to land American astronauts on the moon by 2024 and establish a sustainable human presence on Earth’s natural satellite.

In 2019, NASA revealed details of its vision for the Artemis Moon Lander that will return American astronauts to the lunar surface.

Initial mission capability for 2024 involves landing two astronauts on the moon’s South Pole. Astronauts will live and work out of the lander for six and a half days, according to NASA.

Longer-term, the lander will need to transport four people to the lunar South Pole.

After Apollo 11 astronauts Neil Armstrong and Buzz Aldrin set foot on the moon on July 20, 1969, only 10 more men, all Americans, have walked on the lunar surface. The last NASA astronaut to set foot on the moon was Apollo 17 Mission Commander Gene Cernan, on Dec. 14, 1972.
