But the Mars Society's founder, Robert Zubrin, is highly critical of this plan, saying we already have the rocket technology needed to mount a Mars … Like any venture in any means of travel, there are always things that could go wrong. Efforts to send humans to Mars would likely expose them to health risks beyond the limits of what NASA currently allows, an independent panel of medical experts said Wednesday. The trip to Mars cannot be called risk free. A new study by scientists from UNLV indicates that astronauts going to Mars will be at an increased risk of cancer caused by exposure to radiation. In May 2013, NASA scientists reported that a possible mission to Mars may involve great radiation risk based on energetic particle radiation measured by the RAD on the Mars Science Laboratory while traveling from the Earth to Mars in 2011–2012. Among the most serious health risks for astronauts going to Mars is radiation exposure. There are several key physical challenges for human missions to Mars: Health threat from cosmic rays and other ionizing radiation. The first time we landed on a planet it was Mars, and the first time we roved around the surface of a planet, it was Mars. The astronomical cost of going to Mars – and staying there. What our climate goals and going to Mars have in common is the need for a viable action plan, one that is adaptable, agile and backed by a multi-stakeholder effort. However, there are many other threats a trip to the Red Planet might pose. Current rotations on the International Space Station put astronauts in zero gravity for six months, a comparable length of time to a one-way trip to Mars. Mars mission poses greater risk to human life than Nasa would allow This article is more than 7 years old. "The first time we flew by a planet, it was Mars. Going bonkers might be the biggest. The specific risks of a prolonged stay on Mars can be separated into three distinct types: health risks; habitat specific hazards and hazards associated with extra-vehicular actives (EVAs). written by Quillette Magazine. Share on Twitter. “The radiation hazard of flying to Mars and back is an additional one percent chance of getting cancer at some stage in your life. Humans are going to Mars, and they are going to need some medical support in order to survive the trip, at least according to a panel held last week at a conference in Washington DC. Who should make these decisions? Share on Facebook Share on Linkedin. Filed under: Podcast. The Mars Society often runs Earth-based simulations of life on Mars. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration. “We are concerned about the risks behavioral health and performance would pose to a Mars mission within our current understanding, but we have cutting-edge researchers to help us answer these questions,” he says. Going to Mars will involve all sorts of risks. It’s going to involve risks," McKay says. Image: Mars Society MDRS . Human health hazards. The risks of long-haul human space flight have been known for years. While the effects of Mars-level radiation are unknown, documented effects of radiation exposure just outside of Earth’s atmosphere include vision loss, increased cancer risks, neurological disorders, and more. Space experts say sending humans to Mars worth the risk Summit takes stock of hurdles, technologies, support needed to reach Red Planet by 2030s Going bonkers might be the biggest.
