Twice each day, something strange happens to the atmospheric pressure on Mars.
Is it really colder in parts of the US right now than it is on Mars? Let’s take a closer look. Continue reading “Colder than Mars”
“The article’s basic mistake is in thinking Mars is a closed system. But no planet is a closed system.”
“This NASA article says terraforming Mars isn’t possible “using present day technology.” This is true in the most pedestrian sense. Nobody has a “Mars terraforming machine” sitting in their garage, so the technology doesn’t exist in the present day. BUT /1 https://t.co/Si3GQy627p”
Humans love the idea of a rebel. But only the idea. Take action too far outside the box of current experience and you begin to hear the Greek Chorus of naysayers heckling you, gleefully glomming onto anything that might pull you back within accepted norms.
Such has been the case recently regarding a paper in the journal Nature Astronomy, which reported that there does not appear to be enough CO2 on Mars to allow for terraforming. I can’t count the number of articles that have floated through my various feeds starting with the mocking phrase “Sorry Elon…” Google it yourself and see what I mean.
Mars is a dusty place. Researchers now think much of this dust comes from a single feature on the surface. Overview below. Original article here: https://www.nature.com/articles/s41467-018-05291-5
The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet’s equator, scientists have found.
Here’s a cool animation showing the extent of the dust storm happening on Mars right now.
The dust storm on Mars is a global weather event.
“The last dust storm on Mars to go global occurred in 2007, five years before the Curiosity rover landed at its Gale Crater site, according to officials with NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.”
Some really nice reprocessing of old Viking imagery.
“I am fond of the Viking missions. Their orbits took them far above Mars (as far as 56,000 kilometers from the surface), giving them the ability to take sweeping images of entire hemispheres. Modern missions mostly don’t stray so far from Mars’ surface, and can’t fully capture the same sweeping vistas captured by the Viking Orbiters. ”
Somewhere under those clouds, my characters live. I’m not quite sure where yet.
The Mars Color Imager (MARCI) aboard the Mars Reconnaissance Orbiter (MRO) acquires a global view of the Red Planet and its weather patterns every day. During the week of March 5, 2018, water ice clouds and dust storms were visible.
Given that there are ambitious plans to colonise Mars in the near future, it is surprising how much we still have to learn about what it would be like to actually live on the planet. Take the weather, for instance. We know there are wild fluctuations in Mars’s climate – and that it is very…
