Six Crew Members Emerge from Year-Long Mars Simulation

What kind of person could withstand a trip to Mars and back? NASA and Hi-SEAS is trying to find out.

A crew has emerged from a year-long Mars simulation. On August 29, the six members of the (Hawaii Space Exploration Analog and Simulation (HI-SEAS) IV crew came back to Earth, walking out of their Mars habitat without space suits. The purpose of this and previous studies have been to examine crew cohesion to prepare for a Mars mission. But this mission was special--it was the longest NASA and Hi-SEAS has done, yet.

Prior missions of this nature have been either six or eight months long. The European Space Agency (ESA) has conducted a similar study in Antarctica with the same purpose of anticipating breaks in the human condition during long periods of isolation.

While there are many technological hurdles a Mars mission offers from converting Martian ice to drinkable water and oxygen and protecting astronauts from cosmic rays, there’s a human factor which must be accounted for.

"More than anything it’s just kind of keeping yourself from getting bored and dealing with cabin fever," said crew member Tristan Bassingthwaighte during an interview on Periscope.

But what if astronauts had to endure an 18-month long journey to the Red Planet? One study done back in 2010 examined just that. “The influences of long-term confinement on the human brain are barely investigated,” the researchers write. 

From June 3rd, 2010 to November 4th, 2011 six men were confined to a mock-up space craft as part of the Mars500 program. They found there was a reduction in brain activity and a heightened level of stress—not a good combination for space travel. However, the researchers noted the damage was not permanent. When the participants emerged from their isolation, their levels returned to normal.

The researchers suggest the effects could be offset by exercise, so NASA should pack a treadmill.

It'll take a certain kind of person to withstand such an environment. "You have to be able to adapt to others," HI-SEAS IV crewmember Christiane Heinicke said.

Researchers are continuing to understand out how humans would adjust to confinement with others for a long mission to Mars. NASA and HI-SEAS are actually looking to recruit a crew for their next mission in the simulated Mars hab.

Can the keto diet help treat depression? Here’s what the science says so far

A growing body of research shows promising signs that the keto diet might be able to improve mental health.

  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.

  • It's commonly thought that the suppression of female sexuality is perpetuated by either men or women.
  • In a new study, researchers used economics games to observe how both genders treat sexually-available women.
  • The results suggests that both sexes punish female promiscuity, though for different reasons and different levels of intensity.
