The rover landed on Mars in August to search for habitats that could have supported past microbial life. Results taken during Curiosity's eight-month cruise to Mars indicate that astronauts would receive a radiation dose of about 660 millisieverts during a 360-day roundtrip flight, the fastest travel possible with today's chemical rockets. ...</p><br clear="all"/>
