Mountains of Mars
The volcanic mountains on Mars are truly impressive. Here’s why.
More about terraforming
Here’s a recent webinar on terraforming Mars from the NASA MAVEN Mission to Mars youtube channel. The TL;DR is that it will be monumentally difficult, but sooner or later we are likely to try it. In the meantime, we shouldn’t get hung up on the feasibility of the endeavour as we make plans for exploring and colonizing Mars.
Along the way is a great deal of information on the history of Mars, including the questionable relevancy of its lack of magnetic field, and details on what it would take to terraform a planet.
Terraforming, counterpoint…
“The article’s basic mistake is in thinking Mars is a closed system. But no planet is a closed system.”
X (formerly Twitter) Whither terraforming?
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.
Martian dust
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

CNN Mariner 4
Mariner 4 was the first successful flyby of Mars. On this day in 1965, it made its closest approach and sent the first closeup images of the surface. These were also the first closeup images ever returned of another planet.
Regarding Opportunity
The Opportunity rover has been quiet since this dust storm began. In this video, researchers discuss just how amazingly successful Opportunity has been.
