> When a Mars Simulation Goes Wrong. A recent mission atop a Hawaiian volcano shows humans still have much to learn before they set foot on another world. https://www.theatlantic.com/science/archive/2018/06/mars-simulation-hi-seas-nasa-hawaii/553532/
People love the idea of colonizing Mars; often either ignoring or hand waving away the dangers of living on a planet inhospitable to life as we know it, six or more months away from help if things go wrong.
Thing is? We can't even figure out how to *pretend* we are living on Mars safely…
Yesterday a very brave man passed away. RIP Allan McDonald.

Literally the first time any human being has heard what it sounds like to be on another planet. How cool is that?

Far out, man!

I'm a longtime fan of colonizing asteroid instead of Mars. After all, why fight your way out of a deep gravity well, only to go back down into another one? And the engineering challenges are nearly equivalent.

Oh, wait… They said 'no'. 'No Secret Underground Base…'
Sorry. Please return to your previous Fediversing.

Mystery of Interstellar Visitor ‘#Oumuamua Gets Trickier. Aliens? Or a chunk of solid hydrogen? Which idea makes less sense? https://www.scientificamerican.com/article/mystery-of-interstellar-visitor-oumuamua-gets-trickier/
It appears the 'natural object' explanations for Oumuamua aren't passing the Occam's Razor test; instead getting more and more complicated in order to support the known facts.
Cool, cool… I've been team "Discarded Solar Sail' for a long time now anyway.
After 30 years of searching, astroboffins finally detect the universe's 'missing matter' – using fast radio bursts. https://www.theregister.co.uk/2020/05/29/fast_radio_matter/
This isn't 'dark matter', but rather detritus left over from the Big Bang which never coalesced into stars and galaxies.
If they can get a good measurement of how much there is out there in the universe's 'wastelands', they could possibly confirm current theories of the Big Bang.
ESPRESSO confirms the presence of an Earth-sized planet around the nearest star. https://phys.org/news/2020-05-espresso-presence-earth-nearest-star.html
It's sort of in the habitable zone, albeit with a far different kind of sun than our own and very likely the planet is also bathed in hard radiation much of the time.
There may even be a second planet as well. So much more information to come.
Here's your weird #COVID19 news of the day: a ham radio operator in lockdown had the time to look for an old military satellite in geosync 'graveyard' orbit. This is a great read. https://www.npr.org/2020/04/24/843493304/long-lost-u-s-military-satellite-found-by-amateur-radio-operator
70,000 years ago, a nomadic star came within a light-year of the Sun, likely sending dozens of comets and asteroids tumbling out of the solar system. http://www.astronomy.com/news/2018/03/wandering-star-shook-up-the-prehistoric-solar-system
"… researchers analyzed the orbital evolution of 339 known minor objects (like asteroids and comets) with hyperbolic orbits that will eventually usher them out of the solar system."
A Rare Meteor Shower May Grace The Skies Tonight. https://www.npr.org/2019/11/21/781738197/a-rare-meteor-shower-may-grace-the-skies-tonight
"With a bit of luck, people in the Eastern United States will be able to witness a rare meteor shower known as the Alpha Monocerotids late Thursday night. Two astronomers predicted the outburst will last less than an hour and could even yield more than 400 #meteors in that time."
