How to Get to Mars: 'Trailblazing' Experts Talk Red Planet Exploration







		A trip of a month. Docking in a distant moon. What scenarios would make a human journey to Mars possible? 

		At the end of September, four experts participated in a one-hour conversation about the mission of Mars it would actually look like "One night with pioneers: are we going to Mars?" It took place at the Rensselaer Polytechnic Institute in Troy, New York, on September 26.

		"There's a romantic aspect to this," said theoretical physicist Sylvester James Gates Jr. during the event. "Because Mars, of all our sister planets, is the one that has had the most impact on our culture, in the last hundred years, as a place to think and think."

	Ellen Ochoa, former astronaut of the space shuttle and former director of NASA's Johnson Space Center, explained some challenges in designing a trip to Mars. 

		"We have examined a variety of different things," said Ochoa. "And one of the things that you have to deal with immediately is ... there are really only two types of options: you're there [on Mars] for a couple of weeks, or you're there for almost a year. "

		Ochoa said the short mission option could involve orbiting the planet or landing on one of Mars' low-gravity moons, where the crew could try to send robots to work on the planet's surface before attempting a human landing. And a longer mission could involve humans on the surface of Mars and conduct a closer analysis of the regolith, or dust, of the Red Planet, to perhaps know if it could become a propellant, he added.

		Ochoa also detailed the challenge of fighting. harmful radiation"The problem with radiation, galactic cosmic rays, is that you are receiving this constant dose all the time," he said. Radiation can increase a crew's cancer risk and alter their cognitive ability, according to Ochoa. To help deal with this problem, researchers could focus on designing a magnetic shield to protect passengers and learn how genetic factors play a role in radiation susceptibility. 

		Shirley Ann Jackson, theoretical physicist and president of the Rensselaer Polytechnic Institute, said during the roundtable that all these are possible dangers. "But, in many ways, the real challenge, from a technological point of view, is that they are really interrelating challenges and vulnerabilities" that could be addressed by investigating research from other disciplines. "But there lies the opportunity," he said.

		Jackson proposed that mission team designers learn by observing fields of science such as biology and oncology to develop deep space space flight materials. 

		Would collaboration between governments also be necessary, as Jackson argued in all scientific disciplines?

		"Right now, there's a lot of competition," said Thomas E. Zelibor during the event. He is the CEO of the Space Foundation, a nonprofit organization that advocates space activities. "If you look at the commercial companies that launch into the front space, as I call them, the military-industrial complex, [or] Traditional people we think about, there is tremendous competition going on. But I think they will be forced into a cooperative environment, "Zelibor said, or he said," there simply is not enough money to do it. "

		NASA has moved in the direction of private companies In the last 10 years, according to Ochoa. "We [at NASA] we really change our model in terms of how we work with companies ... we are now buying services; We do not own the spacecraft, "Ochoa said, and companies now have more decision-making power over how they will fulfill the requirements of space flights, he added. 

		Ochoa said companies are also free to look for other clients. "NASA is clearly still the main customer of the exploration of human space ... there really is not another great client, but there is hope that it will grow," Ochoa said. "So, we have really changed the model of how we work."
