The parameters of the second mission haven\u2019t been fleshed out publicly, but Isaacman said from the beginning that the third mission will be the first crewed flight of a SpaceX Starship rocket.<\/p>\n<p>\u201cAt twice the thrust of the Saturn V [rocket], it could very well be the 737 of human spaceflight someday, but it will certainly be the vehicle that will return humans to the Moon and then onto Mars and beyond,\u201d Isaacman said. \u201cEvery one of these missions will be filled with a number of objectives that are meant to accelerate SpaceX\u2019s vision to make life multi planetary, but you can always count on, just as it is with this mission, we will use every bit of the time available for science and research as well as supporting St. Jude Children\u2019s Research Hospital.\u201d<\/p>\n<p>Isaacman and his crewmates have four main objectives over the course of the five days they will spend on orbit:<\/p>\n<ul>\n<li>Achieve an Earth-orbit altitude record at 1,400 km (879 mi) apogee<\/li>\n<li>Conduct the first commercial spacewalk using SpaceX-designed extravehicular activity (EVA) suits<\/li>\n<li>Perform a technology demonstration of Starlink onboard the Dragon spacecraft<\/li>\n<li>Conduct about 40 experiments from 20 partner research institutions<\/li>\n<\/ul>\n<p>Menon said the science data collected during the mission doesn\u2019t end when the crew splashes down off the coast of Florida at the conclusion of their mission.<\/p>\n<p>\u201cWhen we get back, we will be recovered by the SpaceX recovery vessel and then we will owe some time to science and research and reconnecting with our families,\u201d Menon said.<\/p>\n<figure id=\"attachment_67133\" aria-describedby=\"caption-attachment-67133\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-67133\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_orbit.jpg\" alt=\"\" width=\"876\" height=\"494\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_orbit.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_orbit-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_orbit-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_orbit-768x433.jpg 768w\" sizes=\"(max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-67133\" class=\"wp-caption-text\">A graphic illustrating the apogee of the Polaris Dawn mission\u2019s orbit.

The first day on orbit will include raising Dragon\u2019s apogee and passing through the inner regions of the Earth\u2019s Van Allen radiation belt, an area that sees additional charged particles, largely from solar wind.<\/p>\n<p>The region was first discovered in 1958 by astrophysicist James Van Allen and it was most recently encountered by the Apollo 17 astronauts during their return trip from the Moon in 1972.<\/p>\n<p>\u201cWe stand to learn quite a bit from that, in terms of human health, science and research. If we get to Mars someday, we\u2019d love to come back and be healthy enough to tell people about it,\u201d Isaacman said. \u201cSo, I think that it\u2019s worthwhile to get some exposure in that environment.<\/p>\n<p>\u201cIt also informs vehicle architecture because, generally speaking, vehicles don\u2019t like radiation. So that\u2019s why we\u2019re going to stay there for the shortest amount of time that\u2019s necessary to gather the data we want.\u201d<\/p>\n<p>Beyond the human research benefit of this, Bill Gerstenmaier, SpaceX\u2019s vice president of Build and Flight Reliability, said the mission\u2019s dynamic flight profile will also help the company towards certifying their Crew Dragon spacecraft beyond five flights.<\/p>\n<p>\u201cThe high altitude will give us exposure to this high-radiation environment, which will test a lot of avionic systems and their ability to recover,\u201d Gerstenmaier said. \u201cWe build a lot of auto sequences to take care of that for us, but we\u2019ll see how it really works. We\u2019ll also get a chance to see the laser communication, which I think is a big deal moving forward.\u201d<\/p>\n<p>That laser communication is a demonstration of Starlink internet connectivity onboard a Crew Dragon spacecraft. During her remarks, Gillis showed an image of a Starlink WiFi router nested into the capsule. The Starlink demonstration is set for the fourth day of the mission.<\/p>\n<p>\u201cYou might think getting internet might be as easy as just flipping that switch, turning on your internet, but it\u2019s not. We\u2019re talking about a laser sending information to a Starlink satellite that is moving at orbital velocity [more than 17,000 mph], down to Earth, and then back again,\u201d Gillis said. \u201cIt\u2019s been an incredible development effort by the SpaceX team and on a personal note, I\u2019ve taken specific interest in this development effort and we have a special message that we will share with the world using this technology.\u201d<\/p>\n<figure id=\"attachment_67134\" aria-describedby=\"caption-attachment-67134\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-67134\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_Starlink_demo.jpg\" alt=\"\" width=\"876\" height=\"492\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_Starlink_demo.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_Starlink_demo-300x168.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_Starlink_demo-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_Starlink_demo-768x431.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-67134\" class=\"wp-caption-text\">A rendering helping to illustrate the Starlink demonstration that will be performed during the Polaris Dawn mission.

The full operation will take roughly two hours, during which time, both Isaacman and Gillis will egress the vehicle, one at a time, while remaining attached to a roughly 12-foot-long tether.<\/p>\n<p>Gillis said the suit went through quite a bit of modification and iteration to reach the final version that will support the extravehicular activity on the third day of the flight.<\/p>\n<p>\u201cWhen we first started, we would come in every day for training and pretty much every single day, we\u2019d walk in and there\u2019d be a different suit. It would have a different glove, a different elbow, a different shoulder and there was this constant iteration of suit components with the suit team to test and collect data,\u201d Gillis said. \u201cIn parallel with that though, we also had to develop training for that suit.\u201d<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-67136\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_EVA_testing-1.jpg\" alt=\"\" width=\"876\" height=\"494\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_EVA_testing-1.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_EVA_testing-1-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_EVA_testing-1-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_EVA_testing-1-768x433.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><\/p>\n<p>Gillis described a special harness that simulated weightlessness while inside the EVA suit, since they didn\u2019t have the ability to constantly put the suit into a pool for testing. She said it also went through thermal vacuum testing to ensure it could stand up to the harsh environment of space.<\/p>\n<p>\u201cWe\u2019ve covered everything from life-cycle testing, pressure testing, MMOD testing, extreme hot and colds testing, an entire campaign on ESD and flammability testing. It\u2019s been a really impressive amount of work by the SpaceX team to test this suit for flight,\u201d Gillis said. \u201cAs a crew, we\u2019ve spent probably more than 100 hours in this suit at this point\u2026 We\u2019re really looking forward to testing this first generation of suit.\u201d<\/p>\n<p>She noted that during the spacewalk, the Dragon spacecraft will be oriented in a way that will shield the crew members from direct sunlight.<\/p>\n<p>Isaacman said that while he and Gillis in turn won\u2019t be free-floating outside of the spacecraft, he said they will fully exit the vehicle during the spacewalk. He said during the operation they will be \u201cwell above where the hatch is.\u201d<\/p>\n<p>\u201cWe have a hands-free demonstration where it\u2019ll only be our feet engaged in a mobility aid, we\u2019re just not going to be just floating around,\u201d Isaacman said. \u201cIt takes a lot of effort to move in the suit when it\u2019s pressurized. What looks like really heavy clothing, becomes super rigid when it\u2019s pressurized.<\/p>\n<p>\u201cSo, you want to be very deliberate with your movements. You want to make good use of mobility aids.\u201d<\/p>\n<p>Gerstenmaier, who came to SpaceX following a decades-long career at NASA said it\u2019s been a fun process creating the suits and now being on the cusp of seeing them used in practice. He described the process as leveraging knowledge from NASA and \u201cthen we push it a little bit further in other areas,\u201d making sure to share lessons learned along the way.<\/p>\n<p>\u201cThis pace of development that we get to do at SpaceX is very much like the pace of development that was required back in the early Apollo days,\u201d Gerstenmaier said. \u201cWe\u2019re getting a chance to do that again where we\u2019re really starting to push frontiers with the private sector and learning new things that we would not be able to learn by staying in the risk-free environment here on Earth.<\/p>\n<p>\u201cIt\u2019s time to go out. It\u2019s time to explore. It\u2019s time to do these big things and move forward.\u201d<\/p>\n<figure id=\"attachment_67137\" aria-describedby=\"caption-attachment-67137\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-67137\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_crew_Dragon.jpg\" alt=\"\" width=\"876\" height=\"579\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_crew_Dragon.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_crew_Dragon-300x198.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_crew_Dragon-678x448.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/08\/20240819_Polaris_Dawn_crew_Dragon-768x508.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-67137\" class=\"wp-caption-text\">The members of the Polaris Dawn mission pose in front of a SpaceX Dragon training module while wearing their extravehicular activity suits.
