NASA’s Ingenious Mars Rover Fix // Special Earth // Space LEGO from ESA

Plate tectonics could be incredibly rare, LEGO bricks made from actual space rocks, mapping the Milky Way’s dark matter halo, and Perseverance’s SHERLOC instrument is fully operational again.

Lego regolith? Legolith.
We should send up James May to build the first outpost. He has experience in this field.

Is there anything NASA and its engineers can’t do? Bravo engineers and scientists!😊

[davidhuber]

I think "sneaker zoom" was the term you were looking for.
As always, wonderful coverage of the universe about us. Thank you for that.

[glcol]

Never forget, we only got pretty sure proof there were exoplanets in 1992. That always blows my mind, and shows how fast knowledge grew after that first discovery.

[davidhanna]

Great, just effing great, now i wi be stepping on moon lego's at night on tbe way to the john.

[mrwolsy]

Lego will hopefully relinquish patents expressly for the lunar outpost construction, a much smaller 3d printer could be used then.

[Spherical_Cow]

Without plate tectonics, there are no long-term (over hundreds of millions of years) sustainable continents: all seamounts would erode and/or subside back to below sea level, and so there wouldn't be any life adapted to dry land.

It's a somewhat popular (and plausible) hypothesis that life confined entirely to ocean environments would never achieve the levels of complexity required to cope with much more challenging and variable conditions on dry land. Or at least, it would evolve much more slowly because its environment is so much more stable and less varied.

[FlashGeiger]

I wonder if we have plate tectonics because of the early collision that knocked off a chunk of our crust making the moon. That would leave a crust with different thickness in different areas, promoting the convection below that energizes tectonics.

I voted for the equipment fix on the Mars rover. But the owl and robin video was great. Please share more of your home environment.

[lostpony]

I was gonna go with the space lego but, confirming a constant hail of impacts on Mars is way cool because Elon will need a meteor-shooty thing for his mars base. I wanna see the cybertruck space laser or whatever

[overtoke]

we need a couple more seismometers on mars

[Dan-Simms]

Nice big beautiful owl, we kinda had a pet owl, it randomly starting hanging out in our chicken coop every night when it was young, and it stuck around for many years, it got so used too me coming in every night to close up and check for eggs that I could pet it.

[tsbrownie]

Why crush up moon rocks when you can vacuum up dust (which is a bother)?

[joshmiller]

@12:16 I thought we were witnessing the demonstration of the Genesis Device 🖖

[das]

It's an interesting point about data and astronauts taking the movies up . Data is light and is easily transmitted . So the real gain is taking the software, the intelligence and not the material.using on planet material is a far better use of our ability. Learning to adapt the materials on moon to build tools that can build buildings and machines

[znx]

@universetoday could you put the "space bites" or whatever this is called in the title? All of the content is excellent of course, but it would be nice to be able to easily look for these news summaries!

[tyrport]

Are there any estimates of the mass of the Kuiper Belt.

[davidguy]

Canadian Robins are very different to the British equivalent. Much bigger looking. Different beaks, and more.

[obiwanceleri]

That tectonic plate theory sounds a lot like scientists building around the idea the earth is a rare event / is the only place in the universe where there is intelligent life. The conclusion should happen AFTER you make your study.
Hey, what do I know ...

[gavinrobinson]

Another great video, I appreciate everything that you teach us Fraser! I was wondering does it help the channel more if I watch the video via YouTube? If I watch it via Patreon does it still give the video a view on YouTube?
