Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. While in school he was known for his passion for space exploration and astronomy. He started his blog The Meridiani Journal in 2005, which was a chronicle of planetary exploration. In 2015, the blog was renamed as Planetaria. While interested in all aspects of space exploration, his primary passion is planetary science. In 2011, he started writing about space on a freelance basis, and now currently writes for AmericaSpace and Futurism (part of Vocal). He has also written for Universe Today and SpaceFlight Insider, and has also been published in The Mars Quarterly and has done supplementary writing for the well-known iOS app Exoplanet for iPhone and iPad.
In 2013, in a big success story, a Mars rover and orbiter made a near-simultaneous observation of methane in Mars’ atmosphere. Now a newer mission orbiting Mars – ESA’s Trace Gas Orbiter – has failed to detect methane. Why?
Rain takes different forms on the planets and moons of our solar system. But it also “rains” on the sun, as electrified gas drips from giant magnetic loops in the sun’s outer atmosphere. Read about the sun’s coronal rain.
Mars is a cold, dry desert, but a new study provides tantalizing evidence for liquid water deep below its surface. If it exists, this Mars groundwater might cause the weird dark streaks in Martian craters and canyons.
Devon Island in the Arctic is one of Earth’s most Mars-like places. NASA is there, training scientists and testing technologies for future Mars exploration. Now Google has joined in, to bring Devon Island’s Mars-like wonders to you.
Triton is Neptune’s largest moon. It’s a bizarre and geologically active world – a possible ocean moon – visited by Voyager 2 in 1989. Now, NASA has proposed a new mission called Trident to sweep past Triton again in 2038.
Roboticists are fundamentally rethinking their craft. Particle robots don’t look like biological creatures, but they’re constructed like biological systems, vast in complexity and abilities, yet composed of simple parts. Are they a step toward the proverbial ‘gray goo’?
