He stated that over the past week, they \u201cspent a lot of time pressurized in the EVA suits working contingencies.\u201d<\/p>\n<p>Isaacman clarified as well that, unlike missions to the International Space Station chartered by either NASA or Axiom Space, the crew members of the Polaris Dawn mission won\u2019t launch and land while wearing IVA suits. He said because they are limited with space on this flight, they will only have their EVA suits.<\/p>\n<p>In his conversation with Spaceflight Now, he added that their ride to space and back, the Crew Dragon Resilience, will have some extra demands placed on it to support the planned spacewalk.<\/p>\n<p>\u201cIt\u2019s not an airlock that has to be qualified to vacuum, it\u2019s the entire spaceship that has to be done,\u201d Isaacman said. \u201cYou\u2019re also going to be using consumables at a substantially higher rate than you were before because you\u2019re using oxygen for cooling. So, you need a lot more tanks than a Dragon would typically be equipped for, plus, the air to re-pressurize it. So, a lot goes into that.\u201d<\/p>\n<p>He stated on social media that SpaceX and the Polaris Dawn team are \u201cusing the center pallet for additional tanks\u201d to help bolster the redundancies of the Dragon\u2019s environmental control and life support system (ECLSS).<\/p>\n<figure id=\"attachment_65198\" aria-describedby=\"caption-attachment-65198\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65198\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-rendering-small.jpg\" alt=\"\" width=\"876\" height=\"493\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-rendering-small.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-rendering-small-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-rendering-small-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-rendering-small-768x432.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65198\" class=\"wp-caption-text\">A rendering of a Polaris Dawn astronaut exiting a SpaceX Dragon spacecraft. Graphic: SpaceX<\/figcaption><\/figure>\n<h3>\u201cWicked fast\u201d<\/h3>\n<p>The development of extravehicular activity (EVA) suits is no small undertaking. NASA awarded contracts to both Axiom Space and Collins Aerospace to develop suits that are suitable for deployment on the surface of the Moon and ones designed for operation outside of the ISS.<\/p>\n<p>The EVA suits being developed by SpaceX will likely be closer to the variants used for work outside of the orbiting outpost. However, SpaceX has been extremely tight-lipped about their development.<\/p>\n<p>Isaacman described the EVA suits as \u201cheavier and bulkier\u201d as compared to the IVA version he used during Inspiration4. However, he clarified that it\u2019s because the EVA suit needs to support additional capabilities.<\/p>\n<p>\u201cThe reality is that SpaceX\u2019s pace of development on building an EVA suit is wicked fast right now. And you know, you start with an IVA suit that\u2019s already certified, which is has, under pressure, very little mobility,\u201d Isaacman said. \u201cThere\u2019s no mechanical joints in it and it\u2019s a last line of defense. You\u2019re only using that if everything else around you in the spacecraft failed into an environment where you are throwing away all the safety of your spacecraft and all the redundancies that are built into it. And now all you have is a suit.\u201d<\/p>\n<figure id=\"attachment_65200\" aria-describedby=\"caption-attachment-65200\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65200\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-suit-development.jpg\" alt=\"\" width=\"876\" height=\"584\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-suit-development.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-suit-development-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-suit-development-678x452.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-suit-development-768x512.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65200\" class=\"wp-caption-text\">Polaris Dawn Mission Specialist Anna Menon demonstrates a glove prototype alongside Commander Jared Isaacman (left) and Mission Specialist Sarah Gillis (right). Image: SpaceX<\/figcaption><\/figure>\n<p>SpaceX and the Polaris Dawn team have shared some images of the training process. Poteet said it\u2019s been quite something to go through these paces compared to his prior training in the U.S. Air Force.<\/p>\n<p>\u201cYou know, back in pilot training, we were still using devices and procedures that they were using in the 1950s, 60s, 70s,\u201d Poteet said. \u201cHere, they\u2019re creating thee training devices to simulate something that\u2019s very difficult to simulate: zero gravity, with certain harnesses and, you know, these different monster garage-type devices to offload some of the challenges associated with, you know, being at 1G trying to simulate this whole EVA.\u201d<\/p>\n<p>As of mid-December, Isaacman said they were about 70 percent of the way to their mission launch goal based off their starting point roughly two years ago. He said once SpaceX is able to bring its EVA suits online, that will be a big step forward in the company\u2019s future celestial ambitions.<\/p>\n<p>\u201cThis is important. They envision a future that\u2019s more exciting, where people can journey among the stars. You\u2019re going to need a lot of spacesuits,\u201d Isaacman said. \u201cThey shouldn\u2019t cost hundreds of millions. They should cost a lot less. They should be scalable.\u201d<\/p>\n<h3>Learning from the past, preparing for the future<\/h3>\n<p>Isaacman\u2019s latest updates on the Polaris Dawn mission come on Jan. 27, 57 years after the fire that killed Virgil I. \u201cGus\u201d Grissom, Edward H. White II and Roger B. Chaffee amid a pre-launch test for the Apollo 1 mission.<\/p>\n<p>Sunday, Jan. 28, marks the 38th anniversary of the Challenger disaster.<\/p>\n<p>The team remains acutely aware of the risks of pushing the envelope with human spaceflight, which is why Isaacman said they try to keep the lessons of the past in the forefront of their minds.<\/p>\n<p>\u201cThe early days of the space program with the cosmonauts and, you know, Ed White went through and other astronauts was like, I mean, their masks fogged over, they could barely get back into the Gemini spacecraft,\u201d Isaacman said. \u201cI mean, there is a lot of lessons that were learned that have to be applied to this suit. And [SpaceX has] done it incredibly fast with a lot of testing and development.\u201d<\/p>\n<figure id=\"attachment_65201\" aria-describedby=\"caption-attachment-65201\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65201\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-training.jpg\" alt=\"\" width=\"876\" height=\"584\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-training.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-training-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-training-678x452.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/01\/Polaris-Dawn-EVA-training-768x512.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65201\" class=\"wp-caption-text\">Polaris Dawn Mission Specialist Sarah Gillis conducts a simulation of an extravehicular activity (EVA) at SpaceX\u2019s headquarters in Hawthorne, California.
