NASA to Send Humans to Lunar South Pole

NASA to Send Hunmans to Lunar South Pole

NASA is for making history by sending first humans to explore the region near the lunar South Pole. The Space Agency will fly Artemis III, planned for 2025,  that will mark humanity’s first return to the lunar surface in more than 50 years.


NASA’s Orion spacecraft will be the crew’s ride to and from Earth and into and out of lunar orbit. Orion is the only spacecraft capable of returning crews to Earth at lunar reentry velocities.  Four astronauts will depart from Launch Pad 39B at Kennedy Space Center in Florida atop the Space Launch System (SLS), the only rocket powerful enough to send Orion, its crew, and their supplies to the Moon in a single launch. The crew will be selected from among the most diverse astronaut corps in history, each equipped with unique skills and intensively trained., the space agency said in an official statement.


First the crew will launch to Earth orbit where they will perform systems checks and solar panel adjustments on Orion. Then, a powerful push from SLS’s interim cryogenic propulsion stage will help Orion perform a translunar injection maneuver, setting its course to the Moon.

For several days, the crew will travel toward the Moon and perform corrective engine burns to intercept the Moon’s gravitational field. At the right time and location, Orion will perform a series of two engine burns to place the spacecraft in a lunar Near-Rectilinear Halo Orbit (NRHO). From hundreds of potential orbits, NASA selected NRHO to achieve long-term Artemis goals. NRHO will provide near-constant communications with Earth and access to sites all over the Moon. Because it is gravitationally balanced between Earth and the Moon, this orbit will maximize fuel efficiency. On future missions, NASA and its partners will assemble the Gateway lunar space station in NRHO to serve as a hub for Artemis missions.


Space X will provide the human landing system that will transport Artemis III astronauts from Orion in lunar orbit to the surface of the Moon and back again. SpaceX plans to use a unique concept of operations to increase the overall efficiency of their lander.

Before the crew launch, SpaceX will launch a storage depot to Earth orbit. A series of reusable tankers will carry propellant to the storage depot to fuel the human landing system. The uncrewed Starship human landing system will then launch to Earth orbit and rendezvous with the storage depot to fill its tanks before executing a translunar injection engine burn and traveling approximately six days to NRHO where it will await the Artemis III crew.

When both spacecraft have arrived in NRHO, Orion will dock with the Starship human landing system in preparation for the first lunar surface expedition of the 21st century. Once the crew and their supplies are ready, two astronauts will board Starship and two will remain in Orion. Orion will undock and back away from Starship to remain in NRHO for roughly one orbit around the Moon, lasting about 6.5 days. This will match the length of the surface expedition, so as Orion completes its orbit, the two person surface crew will finish their work on the surface in time to launch back up to meet the spacecraft.


After touchdown, the surface crew’s first task will be to ensure all systems are ready for their lunar surface stay. Then they will rest, eat, and recharge for the first full day of the expedition, NASA said.

During their time on the Moon, the astronauts will do scientific work inside Starship and conduct a series of moonwalks, exiting Starship to explore the surface. The astronauts will don advanced spacesuits, exit through an airlock, and descend on Starship’s elevator. NASA has selected Axiom Space to provide the Artemis III surface suits and spacewalk systems. These suits will give the astronauts increased range of motion and flexibility to explore more of the landscape than on previous lunar missions.

During their moonwalks, the astronauts will take pictures and video, survey geology, retrieve samples, and collect other data to meet specific scientific objectives. The view from the lunar South Pole region will look very different from the photos taken on Apollo missions in the Moon’s equatorial region. The Sun will hover just above the horizon, casting long, dark shadows across the terrain, which the crew will explore using headlamps and navigational tools. The information and materials collected by Artemis III astronauts will increase our understanding of the mysterious South Pole region, the Moon, and our solar system.

Mission control teams on the ground will be in contact with the crew as they relay what they see, hear, and feel. Through mission coverage and the ability to send high quality images and video to the ground with advanced communication technology, they will be sharing a unique new human experience with the world, NASA said.


When their surface expedition is complete, the two astronauts will lift off the surface of the Moon and head back to NRHO in Starship to reunite with their crewmates in Orion. After docking, the crew will spend up to five days in orbit, transferring samples between the vehicles and preparing for the journey back to Earth.

When they reach the optimal NRHO departure point, with all four astronauts back in Orion, they will undock and ignite Orion’s engines, slinging the spacecraft past the Moon, and allowing it to coast toward Earth. The crew will travel about 24,855 miles (about 40,000 kilometers) per hour during reentry into Earth’s atmosphere. Assisted by 11 parachutes, the spacecraft will splash down in the Pacific Ocean where it and the crew will be retrieved with support from the U.S. Coast Guard and U.S. Navy.

Artemis III will be one of the most complex undertakings of engineering and human ingenuity in the history of deep space exploration to date. The astronauts’ observations, samples, and data collected will expand our understanding of our solar system and home planet, while inspiring the next generation.

This mission will usher in a future in which humans consistently access the Moon, and human planetary exploration missions are within reach. Each Artemis mission will increase our knowledge, refine our operations, and prove our technology as we prepare for the first human mission to Mars.
