+ Americans love nature but don't feel empowered to protect it US Edition - Today's top story: Polaris Dawn mission to Earth's orbit will test SpaceX's capabilities for a commercial space program [View in browser]( US Edition | 28 August 2024 [The Conversation]
[The Conversation]( This week could mark a milestone for privately funded spaceflight, in a mission that will test capabilities needed for commercial travel to the Moon or Mars. Billionaire tech executive Jared Isaacman will head the Polaris Dawn mission, which was initially set for Tuesday morning but delayed and then postponed again today. It will be operated by commercial space pioneer SpaceX. Polaris Dawn â the first of three planned Polaris missions â intends to orbit over 850 miles away from the Earth, the farthest a crewed mission has traveled from Earth in over 50 years. It will also include the first ever private spacewalk, where the civilian crew members will test out newly designed SpaceX extravehicular activity, or EVA, suits. During the mission, two of the crew will take the new SpaceX suits outside their capsule and see how they fare in space. Designing spacesuits is very tricky, which is something NASA learned long ago, [space security expert Wendy Whitman Cobb explains](. Testing new suits comes with risk, and this mission will mark the first spacewalk using privately designed suits.
