Our planetary national just got a small more strange. In September, NASA’s MAVEN spaceship at home at Mars to learn the planet’s upper ambiance, and since its influx, the orbiter has chosen up two odd readings: 1) There’s a huge dust cloud waft high over the Martian outside, and 2) Mars has its own aurora.
Both of these discoveries come as a big shock to NASA researchers, since neither space powder nor these kinds of auroras have been experiential over Mars previous to.
Using its Langmuir Probe and Wave tool, MAVEN (which stands for Mars Atmosphere and Volatile development) has picked up little whiffs of plasma that form when dirt hits the spaceship and vaporizes. Dust particle have been picked up by extra space probes all through the astral system, but never previous to over Mars.
The dust seem to be intense between 93 miles and 310 miles over the planet, and there’s extra dust on Mars’ dayside--the hemisphere illuminate by the Sun. Researchers have a figure of theories concerning where these particle come from: They could be the by-product of earlier comet visits or resources shed from Mars’ moons, Phobos and Deimos. The dust might even be pending up from the Martian outside someway. But overall, the researchers aren’t completely sure. “It's hard to appreciate how this material got here,” said Bruce Jakosky, a terrestrial scientist at the campus of Colorado Boulder and the mission's principal researcher.
And then there’s the enigmatic aurora, which MAVEN detected for up to five days in December. Dubbed “Christmas light” by the MAVEN side, the aurora was seen at moderately low altitudes all through Mars’ entire northern hemisphere, which is rather confusing.
