A Trio of Mars Papers Provides Two Explanations to Different Questions
Today, we take a look at three recent papers attempting to explain various phenomena on Mars. One uncovers the cause of discrete aurorae. Another explains the martian haze. And a third actually ends up with more questions than answers. Plus, Boeing’s OFT-2 returns to Earth, ESA’s Solar Orbiter makes its closest approach, and Dr. Pamela reviews the new graphic novel “Galaxy: The Prettiest Star” by Jadzia Axelrod.
