Hawai'i Space Exploration and Simulation (HI-SEAS) mission, headed by its crew members returned to Earth after spending four months on simulated Mars early Friday morning.

This was the very first group to spend a lot of time in farfetched space without experiencing the breeze, sound and chirping of birds, the solace in smelling rain. They only consumed dehydrated food without any refrigeration.
Researchers are feeling thrilled to complete the mission. They were welcomed by the ground support crew and other observers who gathered there to congratulate them.

Kim Binsed, an associate professor at the University of Hawai'i at Manoa and a principal investigator for the HI-SEAS research effort, says "Being isolated from the world is tough to deal with, even when you've got company". This crew has proven to be a strong team throughout the duration of the study.

The team had to settle their conflicts and anxiety by working and adjusting with each other as they can't surf the internet. Physical restriction itself is a big challenge to deal with.

The coordination of team to get the procedures done is a challenging task, says Stedman, a crew member. The disagreements on various issues can crop up. However, they didn't face any wide dispute between them during the mission.

In addition to crew linkage observations, the researchers focus on their own projects to grow plants to consume in space, a trash-to-energy conversion study and the utility of 3D printed surgical tools.

Kim Binsed believes that HI-SEAS will prove to be helpful in understanding the astronaut's team execution under a secluded state. The remote controlled spacecraft takes 150 to 300 days in travelling between Earth and the red planet. The manned journey will take around three years for the trip.

New crew members look forward to involve in another eight-month mission being scheduled in 2015.
