Lichens can survive almost anything, and some might survive Mars (arstechnica.com)
Whether anything ever lived on Mars is unknown. And the present environment, with harsh temperatures, intense radiation, and a sparse atmosphere, isn’t exactly propitious for life. Despite the red planet’s brutality, lichens that inhabit some of the harshest environments on Earth could possibly survive there.

Moon, Mars: China leads to both (spacenews.com)
In the Senate hearing considering the confirmation of Jared Isaacman as NASA Administrator, he and Senator Ted Cruz engaged in extensive dialogue about China. They strongly expressed the view that the United States must get our astronauts back to the moon before the Chinese get theirs there. Isaacman expanded that goal to assert that we should work on sending humans to Mars at the same time.

Can Musk put people on Mars? (economist.com)
HUMAN LAWS can be changed, waived or broken. Physical laws are less biddable. When it comes to putting humans on Mars, which he sees as the first step towards the planet’s settlement and humankind’s salvation, Elon Musk now has little to worry about from human law.

Have we been wrong about why Mars is red? (esa.int)
The Red Planet’s iconic rusty dust has a much wetter history than previously assumed, find scientists combining European Space Agency (ESA) and NASA spacecraft data with new laboratory experiments on replica Mars dust. The results suggest that Mars rusted early in the planet’s ancient past, when liquid water was more widespread.

The Shape of a Mars Mission (idlewords.com)
“From a mathematics and trajectory standpoint and with a certain kind of technology, there’s not too many different ways to go to Mars. It’s been pretty well figured out. You can adjust the decimal places here and there, but basically if you're talking about chemical rockets, there's a certain way you're going to go to Mars.” - John Aaron[1]

Almost buried beneath a recent avalanche of rightwing invective posted by Elon Musk on the platform he owns, X, was one eye-popping statement that made space watchers sit up and take notice: an assertion that humans could land on Mars within four years and be living there in a self-sustaining city in 20.
