Precise navigation will be a necessity for safe human exploration of Mars and other celestial bodies in deep space. A pair of experiments about to get underway could change the way this navigation is done, and for the better.
NASA’s Parker Solar Probe, now on its way toward the sun, must survive the searing temperatures in the solar corona to unlock the processes driving the solar wind and coronal mass ejections that can harm satellites and electronics on Earth. We spoke to the scientists and engineers behind Parker’s thermal protection strategy.
The BepiColombo mission to Mercury, getting underway in October, could answer vexing questions about the innermost planet’s core and its Earth-like magnetic field. And the answers could shed light on planetary matters far beyond our solar system.
NASA’s announcement that it will add a tiny helicopter to its planned Mars 2020 rover came after a series of test flights inside a vacuum chamber proved the feasibility of adapting consumer drone technologies into a craft capable of flying in an atmosphere just 1 percent as dense as Earth’s.
