On Tuesday, September 10th, at 5:23 a.m. EST (03:23 p.m. PST), the Polaris Dawn mission launched from NASA’s Kennedy Space Center in Florida, carrying a crew of four to Low Earth Orbit (LEO). This mission is the first of three that comprise the Polaris Program, a private spaceflight program organized by entrepreneur and private astronaut Jared Isaacman and financed by SpaceX. Since launching, the Resilience Crew Dragon spacecraft has flown higher than any crewed mission since the Apollo Era and passed through parts of the Van Allen radiation belt.

Earlier today, the crew carried out the first private spacewalk in the history of spaceflight!

SpaceX Shows Off Its New Extravehicular Activity Suit

In February 2022, SpaceX and entrepreneur/philanthropist Jared Isaacman (commander of the Inspiration4 mission) announced they were launching a new program to “rapidly advance human spaceflight capabilities” while supporting important charitable and humanitarian causes here on Earth. It’s called the Polaris Program. In a recent press release, SpaceX revealed the spacesuits its Polaris astronauts will be wearing (up top) and described the research crews will conduct during the program’s three human spaceflight missions – the first of which is scheduled to launch this summer!

Considerable effort goes into the design of space suits and space agencies across the world are always working on improvements to enhance safety and mobility of the designs. NASA is now working with Collins Aerospace to develop their next generation spacesuit for the International Space Station. The new designs are tested extensively and recently, the new design was subjected to a ZeroG flight on board a diving aircraft.

Lunar Astronauts Will Need Easy Walking Trails Around the Moon's South Pole

Before this decade is out, NASA plans to return astronauts to the Moon for the first time since the Apollo Era and build the necessary infrastructure to keep sending them back. And they will hardly be alone. Alongside NASA’s Artemis Program, the European Space Agency also plans to send astronauts to the Moon and establish a permanent habitat there (the Moon Village), while China and Russia are working towards creating the International Lunar Research Station (ILRS). Numerous commercial space companies will also be there to provide crew transportation, cargo, and logistical services.

All of this will happen in the Moon’s southern polar region, a topographically complex region characterized by craters, permanently shadowed regions (PSRs), and undulating slopes. This terrain could prove difficult for crews conducting extravehicular activities (EVAs) away from landing sites and habitats. In a recent study, an international team of researchers used data from NASA’s Lunar Reconnaissance Orbiter (LRO) to create a detailed atlas of the region that accounts for all the traverses and descents. This atlas could prove very useful for mission planners as they select landing sites for future exploration.
