Mars Explorers Face Huge Radiation Problem

A radiation sensor inside NASA’s Curiosity Mars rover shows that even under the best-case scenario and behind shielding currently being designed for NASA’s new deep-space capsule, future travelers will face a huge amount of radiation.

The results, based on Curiosity’s 253-day, 348-million-mile cruise to Mars, indicate an astronaut most likely would exceed the current U.S. lifetime radiation exposure limit during one round trip mission.

“Even for the shortest of missions we are perilously close to the radiation career and health limits that we’ve established for our astronauts,” NASA’s chief medical officer Richard Williams told a National Academy of Sciences’ medical committee on Thursday.

The Institute of Medicine panel is looking into ethics and health standards for long-duration spaceflights.

Curiosity, which landed inside a giant impact basin near the Martian equator on Aug. 5, 2012, continues to collect radiation data as it conducts its primary mission to look for habitats that could have supported ancient or possible present day microbial life.

Curiosity’s Radiation Assessment Detector, known as RAD, measures the amount and energy levels of highly energetic particles in galactic cosmic rays and from the sun. Scientists then converted the data into radiation dosage units known as sieverts, which are associated with increased cancer risk.

Current U.S. standards limit an astronaut’s lifetime radiation exposure to 1 Sievert, or 1,000 milliSieverts, which equates to about a five percent chance increase in developing a fatal cancer.

A new study shows that with currently available propulsion technologies and similar shielding to Curiosity’s, astronauts on even the shortest roundtrips to Mars would get radiation doses of about 662 millisieverts and that doesn’t include radiation dosages for any time spent on the Martian surface.

“We have a challenge,” Williams said during a webcast meeting on Thursday of the spaceflight health and medical ethics committee.

“We have the probability that in pursuing exploration-class missions beyond low-Earth orbit of long-duration that we will exceed the standards that we have already promulgated inside the agency. We need the advice of the committee on how best to go about proactively resolving some of these potential conflicts,” Williams said.

In general, Curiosity’s shielding was more effective against particles emitted during solar storms, known as coronal mass ejections, than galactic cosmic rays.
