In a groundbreaking moment in space exploration history, a crew of four private astronauts made headlines in the early hours of Thursday by conducting the first commercial spacewalk from their SpaceX Dragon capsule. The spacewalk marked a pivotal moment in the five-day Polaris Dawn mission, which began with the flow of oxygen into the astronauts' spacesuits at 6:12 AM ET.
While only two of the crew members actually ventured outside the spacecraft, all four had to don the new SpaceX-made suits due to the Dragon capsule lacking an airlock, necessitating the entire spacecraft to be depressurized. This spacewalk, also known as an extravehicular activity, has traditionally been the domain of government astronauts for repairs, maintenance, and scientific experiments during human spaceflight.
The SpaceX spacesuits worn during the spacewalk are notably lighter and more mobile than the bulky NASA suits, with a key difference being the absence of the traditional backpack. Instead, life support systems are supplied through a 12-foot umbilical cord connected to the spacecraft, allowing for increased mobility and efficiency.
As the crewmates monitored the spacewalk, the remaining members carefully observed the progress before repressurizing the spacecraft, completing the operation in under two hours. This milestone achievement serves as a significant step forward for SpaceX's private spaceflight ambitions, particularly in the context of future crewed missions to Mars.
The Polaris Dawn mission has already achieved remarkable feats, including reaching a high point of 1,400 kilometers and conducting various science experiments and tests of laser communications with Starlink internet satellites. The crew is expected to return to Earth in the coming days, further solidifying SpaceX's position in the realm of space exploration.
In conclusion, the successful completion of the first commercial spacewalk by private astronauts on the SpaceX Dragon capsule is a testament to the advancements in space technology and the future possibilities of human spaceflight. This historic moment not only paves the way for future space missions but also underscores the potential for private entities to play a significant role in the exploration of outer space.
