Mars Science Lab Begins Radiation Assessment

NASA’s Mars Science Laboratory Curiosity, which launched on November 26 and is now en route to Mars, has begun taking measurements with RAD. RAD is the Radiation Assessment Detector aboard the rover and is the first of the ten instrument suite to be engaged. 

Although radiation monitoring has been performed many times in space, it is usually assessed from the outer surface of a spacecraft. RAD, on the other hand, was designed to measure radiation as a human would experience it – from inside the shielded interior.  “The instrument is deep inside the spacecraft, the way an astronaut would be, “said Don Hassler, RAD’s principal investigator. “Understanding the effects of the spacecraft on the radiation field will be valuable in designing craft for astronauts to travel to Mars.”

In the video below, Hassler explains how this radiation study is unique and will help pave the way for deep space crewed missions.

Having wandered into professional writing and editing after a decade in engineering, science, and management, I now enjoy reintegrating the dichotomy by bringing space technology and policy within reach of an interested public. I lead a fantastic all-volunteer staff as Managing Editor of Space Safety Magazine and keep my pencil sharp as Proposal & Publication Manager for INNOVIM, a NASA/NOAA contractor. In my spare time, you’ll find me advocating for greater appreciation of the International Space Station, supporting International Space University projects, and every so often, reading a book.
