I’ve been working on the next book, and so haven’t mentioned all the cool stuff going on with Mars this month. Over the past week, two spacecraft successfully inserted themselves into orbit around the planet.
The Hope orbiter, from the United Arab Emirates, will be studying weather patterns.
The Tianwen-1 mission, from China, is composed of an orbiter, deployable camera, lander, and rover. The overall mission objective is to search for evidence of life and to assess the environment. The lander and its rover will attempt to land in May of this year.
And next week, on the afternoon of February 18, Perseverance will land in Jezero Crater. Perseverance will be looking for evidence of past and present life, testing oxygen production technology for future human missions, collecting rock and regolith samples for eventual return to Earth, and flying the first helicopter on Mars.
For more information on Perseverance, check out this in-depth article from The Smithsonian.
As the wind of the dust storm blew, billions of dust particles collided with and slid past the primary surface antennae array. Over time, this rubbing of dust on metal caused an electrical charge to build up on the array. Rub a balloon on your hair and stick it to the wall. Rub your socked feet in the carpet on a winter evening and then touch your sibling. These are examples of such static charges.

As they walked, Sally told them about dust storms. She used words like “polar vortex” and “baroclinic wave”, which the kids did not understand but which made sense to them as she spoke. One of Sally’s teaching tricks was to use words and phrases that the kids did not know in ways that made their meaning obvious.

A new study suggests lightning may be weak or nonexistent in Martian dust storms. Researchers vibrated basalt grains at various atmospheric pressures to test their ability to build up charge.
Lightning in a dust storm plays a role in my forthcoming book, Air: Generation Mars, Book One. Hard science fiction is a moving target. Still, the fictional strike in question is weak and only damaging to electrical equipment, so I think it’s plausible.
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.”
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
Here’s a cool animation showing the extent of the dust storm happening on Mars right now.
