In een NASA-artikel van 20 juli worden zaken op een rij gezet.
Human Exploration of Mars is on the Horizon
[-]We have a big agenda to return to the Moon by 2024, and to do so sustainably by the end of the decade. Our sights remain set on sending humans to Mars and the Artemis program will give us the experience living on another world closer to home. Artemis missions on and around the Moon will help us make our next giant leap while robots like the Perseverance rover pave the way for our first human explorers to Mars.
Among the investigations onboard, the rover will carry two that will support future crewed missions to the fourth planet – one to produce oxygen from the Martian atmosphere and another to aid in development of weather forecasting. The mission will also use new terrain navigation and landing technologies as well as study how a potential spacesuit material is affected by the Martian environment.
[-]An investment in the Moon is an investment in Mars
We’re going to the Moon with the purpose of getting to Mars – I absolutely believe this is the right approach technically and politically. What do I mean by that? It means we’re prioritizing investments today in lunar exploration that support successful human exploration of Mars in the future. Both destinations are hard, but possible with our current approach.
[-]We’re planning for our first round-trip voyage to Mars to take about two years using advanced propulsion systems to enable a faster journey while limiting radiation exposure for our astronauts and other mission risks. Our preferred launch window will give the crew about 30 days on the Martian surface, which is ample time to search for life on another world. Other options could require crew to be on the surface for more than a year and away from Earth for as long as three years, but it will be a long time before we have the funding, technology, supplies, and capabilities to sustain such a mission.
