Drill, rocket launch, catch, ferry, repeat?

The Airbus spacecraft will have to manoeuvre itself into a position to capture these samples that will be packaged inside a football-sized container.

After ingesting this container, the satellite must then prepare it for return to Earth.

This means not only shipping it across hundred of millions of km of space, but also putting the football inside a re-entry capsule that can be dropped into Earth’s atmosphere to land in an American desert.

This would be, indeed, a feat of engineering as well as a first in interplanetary exploration.

But I wouldn’t go so far as to call it an “interplanetary cargo ship.” Unless the intention is to maintain it as a permanent link between research locations (i.e., some kind of permanent orbitor stationed above the Jezero Crater) and research facilities on Earth (or the Moon, or the International Space Station).

Political will is needed in addition to the enormous funding. Semi-privatization, anyone?

Mars GLOWS green — but brighter at day than at night

By studying Mars’ green glow, the researchers can understand the structure of this layer in the planet’s atmosphere, better understand its altitude range and even observe any changes in reaction to the sun.

First time to see a “green glow” around another planet. In the case of Earth, it’s mostly caused by oxygen, but Mars’ glow is primarily CO2.

So there really ARE “Green Martians.” Just don’t turn and run!

I Only Wanted to See You Under the Iron Rain…

Wasp-76b, as it’s known, orbits so close in to its host star, its dayside temperatures exceed 2,400C – hot enough to vaporise metals.

Hmm….this reminds me of…let me think for a minute…wait, I got it…

Anakin-TooHot

Yeah, that’s the one. I think.

(Seriously, check it out. Not even the Jedi could possibly handle an actual “inferno” planet.)

Khufu, I mean, Cheops is a go!

Ever wonder this about “Super Earths”?

Do they have atmospheres and how thick are they? What kind of clouds? Do they possess oceans on their surface? Do they have rings and moons? Cheops ought to be able to address such questions just from looking for these tiny dips in light during a transit.

ESA finally does something! Wow. Go Europe!

I love how BBC says “The Americans” when referring to NASA, as if a) American is an ethnic group and b) all NASA scientists are American.

But anyway…

Prof Didier Queloz, who won this year’s Physics Nobel for discovering the first planet orbiting a Sun-like star in 1995, was on hand to watch the launch.

You can watch/listen to his interview here.

ESA and NASA? Airbus? Still not ready? 🤦‍♂️

Right now, engineers have got a dummy rover practising the business of retrieving packaged rock samples. And, yes, the stand-ins really are whiteboard markers.

Yay! Whiteboard markers. Um. OK.

But different agencies and companies are finally working together?

Great!

Wait. What’s the catch?

It is, though, going to take more than a decade to achieve.

Sigh.
