On Sol 4 of the Galahad-1 mission, history was made as the first humans set foot on the surface of Mars. Commander Sarah Patel and Flight Engineer Chang Wu emerged from the airlock of the Pendragon Station habitation module at 7:13 am Mars local time, clad in their extravehicular activity suits, and took their first steps onto the red planet. The moment was captured by the onboard cameras and broadcast live to a worldwide audience of millions.

The astronauts were able to move around with relative ease thanks to the low gravity on Mars, which is only about one-third that of Earth. They took samples of the Martian soil and rocks, which they will later analyze back at the station. They also collected data using a variety of instruments to study the planet's geology, atmosphere, and magnetic field.

During the walk, the Galahad-1 crew communicated with Mission Control at JPL, as well as their families and friends back on Earth, via a satellite relay orbiting Mars. The walk lasted just over four hours, and the crew returned to the safety of the habitation module, tired but exhilarated by the experience.

The Marswalk was a major milestone for the Galahad-1 mission, and for human exploration of space. It was the culmination of years of planning and preparation by a dedicated team of scientists, engineers, and support staff on Earth, and demonstrated the remarkable capabilities of the human spirit and technology.
