The next generation of lunar exploration missions will have larger landing party of four astronauts, who will stay for extended periods on the lunar surface. Initially, Altair will serve as the surface habitat for a new generation of space explorers who will, over time, build a lunar outpost that will allow for even longer stays. The Moon will function as a testbed to prepare humans for further exploration to include Mars. .

While into space for the first time in this launch vehicle will allow Orion to reach an altitude high enough to meet the objectives for December 2014. this test, a much larger, human-rated rocket An uncrewed test flight called Exploration will be needed for the vast distances of future Flight Test-1 will test Orion systems critical to exploration missions. To meet that need, NASA crew safety, such as heat shield performance, is developing the Space Launch System, which separation events, avionics and software will give Orion the capability to carry astronauts performance, attitude control and guidance, farther into the solar system than ever before. parachute deployment and recovery operations. During the uncrewed flight, Orion will orbit The data gathered during the flight will influence the Earth twice, reaching an altitude of design decisions and validate existing computer approximately 3,600 miles – about 15 times models and innovative new approaches to space farther into space than the International Space systems development, as well as reduce overall Station orbits.

  • Concept Study of a Cislunar Outpost Architecture and Associated Elements That Enable a Path to Mars
    Concept Study of a Cislunar Outpost Architecture and Associated Elements that Enable a Path to Mars Presented by: Timothy Cichan Lockheed Martin Space [email protected] Mike Drever Lockheed Martin Space [email protected] Franco Fenoglio Thales Alenia Space Italy [email protected] Willian D. Pratt Lockheed Martin Space [email protected] Josh Hopkins Lockheed Martin Space [email protected] September 2016 © 2014 Lockheed Martin Corporation Abstract During the course of human space exploration, astronauts have travelled all the way to the Moon on short flights and have logged missions of a year or more of continuous time on board Mir and the International Space Station (ISS), close to Earth. However, if the long term goal of space exploration is to land humans on the surface of Mars, NASA needs precursor missions that combine operating for very long durations and great distances. This will allow astronauts to learn how to work in deep space for months at a time and address many of the risks associated with a Mars mission lasting over 1,000 days in deep space, such as the inability to abort home or resupply in an emergency. A facility placed in an orbit in the vicinity of the Moon, called a Deep Space Transit Habitat (DSTH), is an ideal place to gain experience operating in deep space. This next generation of in-space habitation will be evolvable, flexible, and modular. It will allow astronauts to demonstrate they can operate for months at a time beyond Low Earth Orbit (LEO). The DSTH can also be an international collaboration, with partnering nations contributing elements and major subsystems, based on their expertise.

NASA plans to conduct this mission, known as Artemis III, in 2024. Accomplishing this goal will require NASA has made progress by completing some early lunar program development extensive coordination across lunar activities including initial contract awards, but an ambitious schedule decreases programs and contractors to ensure the likelihood of NASA achieving its goal. For example, NASA’s planned pace to systems operate together seamlessly develop a Human Landing System, shown below, is months faster than other and safely. In December 2019, GAO spaceflight programs, and a lander is inherently more complex because it found that NASA had begun making supports human spaceflight. decisions related to requirements, cost, and schedule for individual lunar Notional Human Landing System programs but was behind in taking these steps for the Artemis III mission. The House Committee on Appropriations included a provision in 2018 for GAO to review NASA’s proposed lunar-focused programs. This is the second such report.
