Initially dismissed by traditionalists, it has since grown into a powerhouse that has reshaped the space industry.</p><p>In 2020, it beat aerospace giant Boeing in delivering a safe crewed spaceship to provide rides for NASA astronauts to the International Space Station.</p><p>Today, it launches more rockets than any competitor, and its Starlink satellite constellation provides internet service to dozens of countries.</p><div><a class="fr-green fr-strong" href="https://news.abs-cbn.com/world/2024/9/10/spacex-launches-all-civilian-crew-for-first-private-spacewalk-2133">READ: SpaceX launches all-civilian crew for first private spacewalk</a></div><div><a class="fr-green fr-strong" href="https://news.abs-cbn.com/world/2024/9/10/who-is-on-spacex-s-historic-private-spacewalk-mission-341">READ: Who is on SpaceX&#x27;s historic private spacewalk mission?</a></div><div><strong>- &#x27;Bit of a dance&#x27; -</strong></div><div><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/gvzkIkMFoCs?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span>Prior to hatch opening, the crew completed a &quot;prebreathe&quot; process to purge nitrogen from their blood, preventing decompression sickness caused by nitrogen bubbles. The cabin pressure was gradually reduced to match that of space.</div><p>Isaacman and crewmate Sarah Gillis, a SpaceX engineer, spent a few minutes each peeking out into open space, performing mobility tests on SpaceX&#x27;s next-generation suits that boast heads-up displays, helmet cameras and enhanced joint mobility systems -- before returning inside.</p><p>They didn&#x27;t however float away on a tether like early spacefarers such as Soviet cosmonaut Alexei Leonov or NASA&#x27;s Ed White did in 1965 -- nor, for that matter, did they use jetpacks to fly away untethered as Space Shuttle astronauts did on three missions in 1984.</p><p>Since Dragon doesn&#x27;t have an airlock, the entire crew were exposed to the vacuum of space. Mission pilot Scott Poteet and SpaceX engineer Anna Menon remained strapped in throughout as they monitored vital support systems during the activity.</p><p>&quot;The risk is greater than zero, that&#x27;s for sure, and it&#x27;s certainly higher than anything that has been accomplished on a commercial basis,&quot; former NASA administrator Sean O&#x27;Keefe told AFP.</p><p>&quot;This is another watershed event in the march toward commercialization of space for transportation,&quot; he added, comparing the crewmates to early aviators who paved the way for modern air travel.</p><div><strong>- First of three Polaris missions -</strong></div><p>The spacewalk follows a daring first phase of the mission, during which the Dragon spacecraft reached a peak altitude of 870 miles (1,400 kilometers).</p><p>This put the crew more than three times higher than the International Space Station, in a region known as the inner Van Allen radiation belt -- a zone filled with dangerous, high-energy particles.</p><p>All four underwent more than two years of training in preparation for the landmark mission, logging hundreds of hours on simulators as well as skydiving, centrifuge training, scuba diving and summiting an Ecuadoran volcano.</p><p>Upcoming tasks include testing laser-based satellite communications between the spacecraft and the vast Starlink satellite constellation, and completing dozens of experiments, including tests on contact lenses with embedded microelectronics to monitor changes in eye pressure and shape in space.</p><p>Polaris Dawn is the first of three missions under the Polaris program, a collaboration between Isaacman and SpaceX.</p><p>Financial terms of the partnership remain under wraps, but Isaacman, the 41-year-old founder and CEO of Shift4Payments, reportedly poured $200 million of his fortune into leading the 2021 all-civilian SpaceX Inspiration4 orbital mission.</p><p>The final Polaris mission aims to be the first crewed flight of SpaceX&#x27;s Starship, a prototype next-generation rocket that is key to founder Musk&#x27;s ambitions of colonizing Mars.</p><div><strong>© Agence France-Presse</strong></div>
