A nasa spacecraft set to launch in 2015 will come eight times closer to the Sun than any previous probe, operating within the star’s scorching outer atmosphere, or corona. The $750 million Solar Probe will study the birthplace of the solar wind. During its expected seven-year lifetime, Solar Probe will make seven gravity slingshots around Venus, each time getting closer to the Sun.
