What shape would a giant space cow be??

New SI prefixes clear the way for quettabytes of storage

Re: This is getting silly now

Perhaps not surprising, as it's one hundred hundred, which is nice and neat.

NASA's cubesat makes it to the Moon to test orbit for human visitors

Plan B

Just curious, if the CAPSTONE test shows that NRHO is unfortunately not stable enough, what is Plan B for Gateway? Is there a Plan B?

Look! Up in the sky! Proof of concept for satellites beaming energy to Earth!

There are some Scandinavian governments doing pretty well.

Re: the Mid-Atlantic Regional Spaceport in Virginia

Virginia is in the middle of the US's atlantic coast.

Catching a falling rocket with a helicopter more complex than it sounds, says Rocket Lab

Spherical Cow Silver badge

There was no problem with catching the rocket. The rocket's telemetry glitched so they didn't know exactly where it was, and they decided not to try catching it. I have high hopes for the next one.

California wildfires hit CTRL+Z on 18 years of CO2e removal

Re: All in perspective...

The problem with air being 0.041% CO2 now is that it should be 0.028%. It's a big difference.

Founder of zero-emissions truck venture Nikola found guilty of $1b fraud

This one runs

Nikola does have a working electric truck now, but it's not a ground-up build, just a conversion of someone else's truck.

US Dept of Energy injects more particles of cash into tokamak fusion reactors

The difference between a torus and a taurus is that one is doughnut-shape and the other is spherical (at least, I assume it is).

Re: Yup, space is still hard

It does matter how many: if none are being made, the chance of failure is zero.

11th June or 6th November?

India's Mars Orbiter Mission loses contact, burns all fuel, deemed 'non-recoverable'

Spherical Cow Silver badge

If you can send a fuel tanker all that way you may as well send a new probe with better instruments.

Re: 1.2 million kilowatts

1.2 gigawatts is not quite enough for time travel, you need 1.21 gigawatts for that ;-)

China to launch space tourism by 2025, says industry veteran

Re: suborbital "space" tourism?

The article definitely says "sub-orbital" not "orbital".

"China’s space tourism operators will lift off for first time in 2025 at between $280k-$400k per sub-orbital seat, according to the founder of Beijing-backed commercial launch service provider CAS Space, Yang Yiqiang."

Boffins spot baby planet forming around young star – and that's rather cool

Re: Earworm

Is that where Baby Shark lives?

Re: Torys

Au contraire, jake. Everything is connected and everything influences everything else, which means the Universe wouldn't be what it is today without British politics. Of course the difference would be negligible... but not zero.

Blue Monday for Blue Origin as rocket bursts into flame

Spherical Cow Silver badge

What about when the booster hit the ground? While I haven't seen the footage of that yet, I'm willing to bet that if it was still intact-ish before impact it would certainly have burst into flame at that point.

Spherical Cow Silver badge

Re: It's going to hurt sales

Difficult to tell whether the retros fired, it was behind a rise in the ground.

Re: They must of

- So its "must of" as in must've

But... the apostrophe in must've is a placeholder for the missing ha. It's not of and never has been (despite your regional mispronunciation).

Japan reverses course on post-Fukushima nuclear ban

The new reactors are being designed by proper engineers, not El Reg commentards, and I am 100% certain they are aware of the existence of earthquakes.

Re: saving energy

What's the point of glowing in the dark for a day or two? It would be far more useful to glow in the dark for a night or two.

I like the idea of the single-person suitless space craft. Zipping around in one of those would be fun!

Space Ping-Pong

Formed on Earth, then knocked into space by a huge impact to become part of the moon, then knocked into space again by another impact sending them back to earth: that's pretty amazing stuff! I just hope the next exchange happens after I'm gone.

Scientists unveil a physics-defying curved space robot

Spherical Cow Silver badge

It's just using friction.

Sit on a swivel office chair with your feet off the floor. Stick your arms out and slowly rotate them left then suddenly jerk them right, you'll spin slightly to the left on the chair. Repeat many times and you can turn yourself all the way around.

Watching the video it is obvious the robot is doing the same thing. This has nothing to do with curved space and everything to do with overcoming friction at slow vs fast speeds.

[checks back of envelope]

They've completed one sixth of a six mile wide telescope so... it's one mile wide now??

Clean up orbit first, then we can think about space factories, says FCC

Spherical Cow Silver badge

Re: Big problem with limited solutions

Small things in low orbit will get rid of themselves soon enough. Big things in high orbits are tracked. So if you want to know where to cast your net, the answer is somewhere in between.

Re: Is an ellipse…

It went titsup... did it then come titsdown? I suppose it did, with a premature re-entry.

Virgin Galactic delays commercial suborbital flights again

Re: They still haven't started yet?

"Question is, how much money do they have left to burn?"

The article mentions $1.1 billion in cash and securities, plus $300 million to come from selling more shares.

Boffins put supercomputer on the scent of a perfect landfill deodorizer

You can, you just need the right combination of incense sticks in the right proportions, which is what they are calculating.

US regulators set the stage for small, local nuclear power stations

More *reactive*

The article does NOT say "more radioactive" as many commentards above seem to have assumed.

The article says "more reactive" which is a different thing entirely.

Perhaps the article has repeated a typo, or maybe it means what it says: more likely to react with, say, oxygen or some other common reactant.

SpaceX crewed flight to ISS delayed by damaged rocket

Spherical Cow Silver badge

Re: Science brings us together

Since you wrote that post, Russia has announced they are pulling out of the ISS.

Spherical Cow Silver badge

Once the crewed launch limit has been reached they could still use the capsules for lots more cargo missions. It wouldn't take much effort to remove the seats and screens (which could then be reused).

Re: Tap, tap

I also had a cat who said Hello (Eh-Oh) as a greeting. He had a vocabulary of several distinctively different sounds for use in particular situations.

Depends on how many big expensive space telescopes have been launched in other planetary systems ;-)

Copper shortage keeps green energy, tech ventures grounded

Spherical Cow Silver badge

Re: RTSC

Aluminium is not "a terrible conductor". It is a reasonable conductor, which is why it is used in overhead power lines (and also because copper is heavier and too stretchy).

Spherical Cow Silver badge

That's a lot

425kg of copper in one vehicle! Presumably that vehicle is a truck, because it just doesn't sound reasonable for a family car to have to lug around nearly half a tonne of copper.

These centrifugal moon towers could be key to life off-planet

Re: practical but heavy

I was about to suggest a mercury bath bearing similar to those used in some old lighthouses, but then I remembered the vacuum on the Moon will cause the mercury to evaporate if the bearing doesn't have a really good seal.
