Artwork: Boeing Plans to Build Landscape, Divided into Two Stages

Aerospace giant Boeing has unveiled a landing proposal that can take people to the surface of the moon.

Under a program called Artemis, the White House wants to bring people back to the moon by 2024.

His approach, called "At least Steps to the Moon," would use the giant Space Launcher (SLS) rocket.

The company says its plan reduces the complexity involved in sending multiple different bits of hardware into space in multiple launches.

For most robotic space missions, all the hardware needed for the mission is fired on a single rocket. Similarly, Apollo missions to the moon in the 1

960s and 1970s required only one take-off.

However, Artemis' missions are expected to include several fields to supply all the necessary hardware. For example, the landing elements are likely to be fired separately from the Orion capsule carrier crew.

Boeing says he can land the astronauts on the moon with only five "mission critical events" – such as launching, orbiting, and more – instead of the 11 or more required by alternative strategies.

Nasa said earlier that the preferred option was a moon-catcher divided into three stages, but left the door open for "alternative, innovative approaches".

The Boeing proposal uses only two stages – a descent element that astronauts descend to the surface and an ascent element to get the crew to the surface and back into lunar orbit at the end of the mission. They are designed to be fired as one unit.

The company claims that its lander can be carried from the moon orbit to the surface without an additional transfer element, or "tractor", as previously indicated by Nasa.

This, she said, would further reduce the missions needed for a mission and simplify the steps required for a successful landing.

The company says its lander will be ready for a 2024 mission called Artemis-3. But Boeing's plan will depend on a more powerful version of the SLS rocket called Block 1B.

According to Nasa's current plans, the Block 1B version of the rocket will not be ready by 2025.

Earth will use technologies developed for the CST Spacecraft -100 Starliner

However, Nasa's procurement process allows the use of two separate landowners from different companies in the Artemis-3 and Artemis-4 missions (Artemis-4 is due to fly in 2025).

"Whether serving the Nasa 2024 or the 2025 Mission Slot, Boeing's approach maximizes the return on the agency's investment in past and current programs to allow the simplest and therefore highest probability of a path to lunar surface, "the company said in a statement.

Earth will use key technologies from the Boeing CST-100 Starliner capsule, designed to transport astronauts to the International Space Station (ISS).

The Boeing lander will be able to connect to Gateway, a planned space station in lunar orbit, but it will not require it. Instead, it could contact the Nasa Orion spacecraft directly for a simpler mission profile.

Last month, Amazon founder Jeff Bezos announced the formation of a "national team" that would make a separate bid to build the lander for 2024.

Space company Bezos Blue Origin partnered with aerospace giants Lockheed Martin, Northrop Grumman and Draper to make a proposal for a three-stage perch.
