The Polaris Dawn mission, a groundbreaking five-day journey, has finally come to an end. The four-person crew, comprising tech billionaire Jared Isaacman, former US Air Force pilot Scott "Kidd" Poteet, and SpaceX engineers Anna Menon and Sarah Gillis, splashed down off the coast of Florida on September 15. This historic mission not only marked the first commercial spacewalk but also set a new record for the farthest journey undertaken by humans since NASA's Apollo Program.

As the Crew Dragon capsule returned to Earth, it encountered scorching temperatures of up to 3,500 degrees Fahrenheit, equivalent to 1,900 degrees Celsius. The crew, however, remained comfortable thanks to the spacecraft's heat shield. The capsule then deployed parachutes and slowed down before splashing into the ocean. Half an hour later, the rescue crew recovered the capsule using the "Dragon's Nest" vessel.

What if this assumption is wrong? What if the harsh conditions outside the spacecraft are more challenging than we think? Have we considered the long-term effects of space travel on the human body?

The crew's spacewalk, conducted on Thursday, was a high-stakes challenge that tested the functionality of the extravehicular activity (EVA) suits. Isaacman and Gillis stepped out of the vehicle for about ten minutes each, marking a major milestone in the private space sector. As they gazed out at the vast expanse of space, Isaacman exclaimed, "From here – looks like a perfect world."

But what about the psychological impact of being in space for extended periods? Have we considered the effects of isolation on mental health?

In addition to conducting experiments, the astronauts also found time to relax and have some fun. Sarah Gillis, a trained violinist, played a rendition of "Rey's Theme" from The Force Awakens, which was shared with experts back on Earth via SpaceX's Starlink satellite network. Anna Menon sent her kids "Kisses From Space" by reading a book she co-authored to them and some youngsters at St Jude Children's Research Hospital.

Have we considered the long-term effects of space travel on families and loved ones left behind?

The Polaris Dawn mission has opened up new possibilities for space exploration, but it's essential to consider the potential risks and challenges that come with it. As we move forward, we must prioritize the safety and well-being of both the astronauts and their loved ones.
