Nasa’s 2020 rover: Can we finally answer the big question about Mars?

“So, let’s bring the samples back. So if those extraordinary claims are made, they can be verified.”

One likely extraterrestrial form of life might resemble a terrestrial form: the stromatolite.

They basically look like big rocks. I visited one site in Western Australia in 2003 with a group of Japanese students who were told by a local guide that the stromatolites were “3.5 billion years old.” (They’re not, but they do look like what life might have looked like at that point.”

So NASA is sending another rover to see if they can find evidence of a similar life form.

Sorry. No Slurm (yet?).

Five reasons why NASA is sending a Dragonfly to Titan

It’s the only moon in the solar system with a thick atmosphere.
This atmosphere is more similar to Earth’s (especially ancient Earth’s) than any other atmosphere in the solar system.
Chemistry, baby. Microbes, maybe.
Labs take too long. Experiments on Titan would be short.
The terrain is pretty wild.

Check out the link below for more detailed explanations and a neat video.

The Eagle has landed. Um. Again. Sort of.

Apollo11-reflection

‘As far as audio recordings, we previously had only 48 minutes of off-air audio of the BBC coverage from another source. Now thanks to you we have over eight hours!’

It’s been 50 years since The Eagle landed. There are plenty of existing video and audio recordings from US media sources (like this one on YouTube, clocking in at over 3 hours).

It’s been considerably less time since news recordings of Apollo 11 from *outside* the US were discovered. Just over half a year. Audio only. Bummer. But at least you get a different perspective (always a good thing when it comes to news).

Forget Mars, Head to Europa?

“I think we’ve got a better chance of having slightly higher forms of life on Europa, perhaps similar to the intelligence of an octopus.”

Hmm. Maybe. It seems more like that any life would be of the microscopic or worm-like variety. But we still have to get out there first to find out…

Super Bowl 2020: All the space-themed commercials

“Being able to get humans on Mars and actually collecting one of these samples would be such an incredible moment, I would kind of hope it would almost bring us back to the moon days of everyone being glued to the TV.”

Um. Well. OK. TV is dead so we’ll all be watching it streamed on our smartphones, but the point is taken.

And how much did they pay for this? 💰 👽 📺

It’s a Nice Model you’ve got there, Mars. Be a shame if something happened to it…

“Without this instability, Mars likely would have had a mass closer to Earth’s and would be a very different, perhaps more Earth-like, planet compared to what it is today.”

Damn you, Jupiter and Saturn! Why couldn’t you have just stayed in your orbits and left Mars alone? (Shakes fist futilely at night sky.)

New “habitable” Earth? 🌍

January 10, 2020
MThomas

The newly discovered exoplanet, called TOI 700 d, is located about 100 light-years away from us and is roughly 20% larger than Earth.

Okay, not exactly close, but looking good…

A year on TOI 700 d takes 37 days.

Um. Wait. What?

One thing astronomers have discovered though is that TOI 700 d is tidally locked to its star, which means that one half bathes in eternal sunlight, and the other half always exists in darkness.

Oy.

And even better…

One of the burning questions is whether the planet has an atmosphere or not.

Is this really the best way to phrase this? 😂

I vote we pass on this one…

PS I’ve been trying futilely to get WordPress not to screw up the formatting. To no avail.

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.

It’s life, Jim, but not as we know it. Maybe.

The pattern remains a mystery, but researchers are beginning to narrow the possibilities.

While the changes are most likely…geological in nature, planetary scientists can’t completely rule out an explanation involving microbial life.

Just as the Viking landers claimed? Uh-oh.

Or is it just chemicals (perchlorate, bleach-like substances) in the soil, releasing oxygen and methane depending on the amount of sunlight/heat?

How would this affect humans who set up camps in the low-elevations areas, where they could be closer to water?

Hm…
