Europe's Ariane 6 takes rocket science seriously by testing patience before engines


Madness still

It was 10 years ago that SpaceX proved that the first stage reusability was not only possible but commercially viable.

Yet the ESA paid billions to continue developing another single use rocket. The reasoning that if it was reusable they wouldn't make enough engines to make the engines cheap enough! No looking at if it was reuseable and thus cheaper the launch market can grow.

Shotwell (and not Muskrat) has done amazing to get SpaceX to the global default launcher now. If its not on SpaceX then the customer is a government just trying to keep an outdated launch provider on life support.

Government launchers need to step up and demand reusable rockets asap, or watch their launch capability fade into obscurity.

Not sure why Starlink wouldn't just agree to have all China based customers connections sent back down to only China based base stations.

Regardless of what you think of a counties laws, if you want to provide products/services you follow that countries laws. Musk is quite paly with the CCP.

Russia admits, yup, the Americans are right: One of our rocket's tanks just disintegrated in Earth's orbit


Re: Elon Musk isn't helping, is he

Let’s educate you a little, or try

Starlink sits in very low earth orbit, below the operational height of almost all other sats.

Due to this low orbit, sats fall back to earth within 5 year max for the high test ones and with 3 months at launch orbits even if they lose all power. This is also the reason nobody else is using these orbits, the atmospheric drag is large at this altitude.

As for observations, when starship flys it will be cheaper to Launch a telescope into orbit than to ship it up a remote mountain. Telescopes should be in space and not below 100km of atmosphere.

Starliner snafu could've been worse: Software errors plague Boeing's Calamity Capsule


Re: "re-verifying flight software code"

It’s worse.

They cut and pasted their own code, from the capsule to the service module, but then didn’t update what lookup tables it used.

If not spotted and rushed patched, when the two parts separated, the service module would have used completely wrong thrust, then try to self correct using even more incorrect thrust and so on until it’s out of thrust or has crashed back into the capsule.

Boeing sent multiple, untested, unvalidated software patches, written on the fly to the star liner whilst on mission, just to get it to return safely and it still failed to reach the iss.

The approach and docking at the iss hasn’t been tested.

Let’s not forget this was a proof it all works mission. That without direct intervention would have resulted in total loss.

Astroboffins may have raged at Elon's emissions staining the sky, but all those satellites will be more boon than bother


Re: An interesting point of view

Becasue they are in a very low orbits, which without boosting, delay into teh atmospher in 1 to 5 years. .

No wonder Bezos wants to move industry into orbit: In space, no one can hear you* scream


Re: Accidents

Yes weight is less in lower gravity. Momentium is Exactly the same.

But on the moon you can throw 100KG of mass at sombody accorss the room, whilst that woulnt pin them to the floor like on earth, it will hurt the same when it crashes into them.


Re: McAffe is in the office waiting for you Mr Bezos

Challenge accepted.

Use Methane Oxygen fuel on a fully reusable rocket. As the Methane has to be Made and not from any natural as source (due to purity requirements). The methane is made using the Sabatier process from CO2, and Hydrogen from hydrolysis of Water. Which also generate the O2 needed.

Powering this by solar panels and sourcing the CO2 from the air makes launches carbon neutral.

Thus you can launch a rocket into space polluting less than the truck used to move the payload to the rocket.

You Look Like a Thing and I Love You: A quirky investigation into why AI does not always work



We are getting there.

The world’s most powerful supercomputer is 148 *10E16 Flops and uses 13MW of power.

A human brain is in the same order at estimated processing power between: 0.9 and 33.7 * 10E16 FLOPS but uses just 25W.

Our brains are also hardware and software combined with a lot of pre-programming (some of which is not helpful)

But just think we still take over a year to become slightly self-aware, another year to learn basic language and become conscious, another 4 to get the hang of reading and writing, another decade to make complex decision and still most of us can see the limits of our cognition.

SpaceX flings another 60 Starlink satellites into orbit in firm's heaviest payload to date


Re: Optimism

How much does your amature scope weigh?

At the proposed $2M cost per 150T launch, thats $13 a KG!

Nobody seems to relise how transofrmational that cost per KG really is...

The $2 is including Paying $900,000 for fule. Which SpaceX is going to make for free using Tesla solar pannels, a compressor and the Sabatier process.

Also includes $1M to NASA for Florida launch complex cost. Boca is SpaceX owned and being preped for full launches. $100K for maintance per launch.


Re: Optimism

Viewing the universe thorough an atmosphere is far from ideal.

The answer is what the vast profit from starlink enables. That being StarShip at a cost of $2M to get 150T to LEO, if launched from a NASA complex. It's less than $1m if launched from Boca. Thats less than the cost of lugging 150T up a chillian mountain top!

All telescopes should be space based, its just the vast cost of launching that's prevented that. As the launch cost is so high, sats have to be made not to possible fail, adding yet more cost.

Just imagin what can be built with a $1-2M launch cost, weighing 150T and at 9 Meter wide faring!



Does make me wonder how much success Musk has to have before the naysayers eat their words.

The sats deorbit from drag within 3 months if they break before reaching target orbit.

They deorbit within 5 years at the highest target orbit for starlink.

Very few other sats in these low orbits, because the drag makes their lifespan short.

This batch have the auto avoidance system enabled and should self move out of the way of any potential issues.

Why is anybody on the reg if you don’t want super low latency gigabit internet anywhere.

Then again loads of reg readers still think digital watches are a pretty neat idea.


Re: 59 out of 60

At that low altitude the sats deorbit from drag in a few months at most

Oh chute. Two out of three ain't bad, right? asks Boeing after soft-ish crew module landing


So complex so many points of failure

Really starts to point out why Starship is going to be a stainless steel tank with some thrusters and engins.

All this compelx abort, complex staging, complex landing kit. complex recovery, complex hypergolic fuel handling, complex parachutes. its all just so many points of failure.

Cant wait or the next 5 to 10 years, Startship will be pottering about the solar system, landing on the moon, mars and building bigalo stations.

NASA will be still waiting for the SLS and planning a few dozen stages, super complex crafts, using 1960s technology to get to the moon but be nowhere near it.

Re: Worrying about something a bit prematurely

Commerical is sorted.

SpaceX is building Starlink. This will be a gloabl internet provider, offerign 1GBit internet, at low latency, connects to anywhere on earth for a subscription. This will print money, as in Billions upon billions.

Now with infinite money and private investors who all are buought in on owning Mars or can be bought out easily, commericals just don't matter anymore. This is why starship will carry 150T per alunch and can launch 3 times per day per ship. Thats a whiole ISS per day per ship! Its sure a hell not for any kind of earth orbit payloads. Its for colonising mars in a BIG way.

Not so G.fast: Hybrid fibre 'under review' as Openreach remembers it's all about FTTP now



Is it just me, or are BT saying they are binning G.FAST as they woudl put FTTP in the SAME PLACE!

So rather than leaving the G.FAST as that and using the resorces to make more FTTP happen. They are going to re-do the same locations that have already got G!

They really dont want to roll out to the rest of the UK, just keep upgrading the same cheery picked locations!

SpaceX didn't move sat out of impending smash doom because it 'didn't see ESA's messages'


This would be why they are test sats

Glad this issue has been found before they launch the 1000s of them. Gives insight that the auto maneuvering isn't live yet, just like the between sat coms. Long way to go to get LEO constlations up and running, but thats what testing is for.

For those bashing Tesla's autopilot, have you tried it verses say Toyota lane-keeping assistant? Tesla drives nicly down the road, will go around parked cars, overtakes (on multi lane roads) works nicely almost all of the time. Toyotas latest and greatest system will only keep you in lane and does so like its very drunk, swerving from one side to the other then setting off alarms as IT dives over the lines and thats when the road is clealy marked. Anywhere where its not, the car drives in the middle-ish of the road!

Re: Telecom Companies Rule

Ping is lower. Do some maths :)

Speed the latest fibre cable from NY to Spain has an average transmission speed of just 121,212kph, just on the 4,000km cable, + transmission times from the end of the cable to the endpoints.

Now the Speed of light in the atmosphere is 299700kph. The speed of light in vacume 299792kph.

Can you see where this is going? If you're only broadcasting from source to to Very low earth orbit, accross and back down direct to target, Starlink will have substantially lower ping for translatic coms and the advantage grows the further the points are away from each other. Even a few ms lower will have a huge finical gain to the high-frequency traders.

The only reason old school Sat coms is pants is a Geostationary orbit round trip is a minimum of 72,000 KM.

Gone in 120 seconds: Arianespace aims for stars, misses, as UAE satellite launch fails


WTF uses this rocket

Vega book cost is $37m per launch for just 1,450kg to LEO.

A used Falcon9 launch is about the same cost now and can do 13,500kg to the same orbit.

The UEA could have launch both sats on the same Flacon 9 for the same price as this one on a Vega rocket.

Falcon9 does more successful launches per year than the Vega has ever done and after this failure is actully more reliable including its earlier failures.

Just dont use a Northrop Grumman deployment (use SpaceXs as that works).


Re: Should have gone to India

Or to rather to Mr Musk.

A Whole falcon 9 is $60m if you want a completely new one.

Less than $40m for a one careful user with a full service history.

This is book price before any discounts or ride sharing.

After this crash the Flacon now has better reliability than the Vega, with a vastly superior payload and orbital injection capability.

Re: Of course online poker is ruined

Having worked in the online gambling industry I can say the Poker companies are not doing this themselves.

Its FAR more profitable and less riskly just to provide the service and take a cut of buyin/stakes/winnings. or provide a winning pot and take the business.

Just like when people say a roulette is riged, they miss the point that all the house needs is a small odds in its favor (as is the design of the normal game) and them to play enough games.

33s to make a move is unacceptably slow for real work cases. However I can't see the researchers not having a copy of the code to "try" at home.

Who's been copying AMD's homework? Intel lifts the lid on its hip chip packaging to break up chips into chiplets



And so after years of Intel siting on their assess, price gouging and not innovating, they are now several years behind Ryzen architecture benifits. Whilst AMD is accellerating away with Ryzen 3 this year and 4 due next year, all before Intel has anything close to competing with the Ryzen 3. HOw many years will it take for Intel to bring the connector fabirc to market and designed and fab chips onto it? 5 years?

Chiplets makes a huge difference in the overall cost, as you get vastly greater yeilds making lots of small chipsets on a new fab process (AMDs approach) than you do for single monster sized chips (Intel's approach).

Musk loves his Starlink sat constellation – but astroboffins are less than dazzled by them



Thinks forgotton. These sats deorbit within 2 years maximum if they fail.

If SpaceX gets this up and running, it will be the making of SparShip (BFR) (Starlink is the proposed long term funding source for SpaceX). At which point it will make Heavy lifting so economical that we should move our future telescopes into space. A 100t to geo and a 9-meter faring make a very large telescope. You could pack the James web in without having to fold the mirror! A huge weight and faring makes designing a large space teliscope vastly cheaper.

Next up who doesnt want fast internet accesable gloally?

Forget the other consitlations appart from Jeffs. The only way to complete is to have a cheaper launch capacity, which is impossible unless you own the rocket manufacturing and can make rockets reusable and ten use only rockets somebody else has already paid for with previous flights. The economics of SpaceX really shine on this one.

Re: Sleep is a Good Thing(TM)

I'll make this easy.

Humans emit 35,900,000,000,000KG of CO2 per year and climbing. 1KG of CO2 is enough to fill two baths. Just try and let that number sink in, its huge,

Plants, all of them from the algae in the seas to the forests ran out of capacity to absorb the extra carbon a long time ago. Plans currently taking about half of what we emit. The remaining 17,950,000,000,000KG is accumulating the in the atmosphere per year and every extra KG we emit just stays there. This is why the atmospheric CO2 levels are now skyrocketing. To scale, if you take an average model globe, the atmosphere would be as think as the paint!. It’s not big at all.

CO2 is a greenhouse gas. It traps heat from the Sun in the atmosphere. The more CO2 the more heat is retained from the sun and so the hotter the global average temperature is. We can track the historic CO2 levels (over billions of years) in the atmosphere and they map perfectly onto average global temperatures with a slight lag.

This process is lagged, thus if you put vast amount of CO2 in the atmosphere it takes a few years for the temperature to rise to its new equilibrium temperature. If the CO2 drops it take a good few years for the Earth to cool down. As you may have noticed the earth is quite large and it take a LOT of energy to heat the oceans up, but they store a lot of energy when heated even a little.

Best case we lose most of the ice on Antarctica, and all of it on Greenland, Siberia and the sea levels rises at least 20+ meters. This is already inevitable, the last time CO2 was this high, that had already happened. Now where do humans put all their capital cities? How much of our land is 20M or less than sea-level? Do you like hurricanes, as warmer oceans make them larger and more common.

Worse case is the ocean circulation stops, because of excess fresh water at the polls and warm water at the polls. This has also happened before when CO2 was high and it resulted in the extinction of 99% of all life on earth.

Well no the actual worse case is we hit a tipping point where the system runaways and we make Earth like her sister planet – Venus.

Nvidia keeping mum on outlook for year as data centre slows, channel chokes on crypto crap



Not sure why they thought the RTX woudl be good for mining anyways.

Vega has any Nvida card smashed in Hash per $, Vega Vii is the king, as GPU mining is usually limited by Memory bandwidth. 1TBs HBM2 on Vii compared to 616GB/s on a 2080ti (even a moderatly overclocked memeory on a old Vega 64 has more memeory bandwidth than a 2080Ti).

So ridiculously overpriced RTX series not fit for mining, even if ETH price was still high, Gamers getting not a lot more for 2x the price. But will they do the sensible thing and drop the margins to clear the stock? Nope they will just delay launching anything new untill the old crap is gone.

Absolute mad lads are teaching physics to AI because how else will it learn to solve real-world problems (like humans)


Re: Which laws?

Common misunderstanding.

The laws of physics can be changed and physics are trying to do it, it's just that any change must still agree with the known experimental results.

Einsteins GR agrees with Nutons Laws most of the time, just when you go to more extremes, Newton's laws don't match the data and Einstein's do.

We know the laws of physics are not complete, Einstein's rules don't work in quantum systems and quantum rules don't work at large scales. Both are outstandingly accurate at predicting the results of experiments at their respective scales. Thus any grand theory must predict both to the same or better accuracy.

Feeding a machine learning system all the results and ask it whats the underlying maths is, may just work. If us dumb monkies understand that maths is another matter.

People do need it. Some of us already get much better speeds from a 4G connection than BTs "boardband" internet. Some of us use 4G as our main home connection with an Unlimited data contract.

Some of us are waiting for 5G to come along and will be upgrading the card in our routers to connect to it...

5G could actually offer solid competition to landlines in villages, especially on Three as they have the most frequency allocation, but it does mean they will have to actually upgrade the towers.

Im supprised this story is for Vodaphone, dint think they had 3G yet, sure dont anywhere I've lived.

By By BT land line in the sticks

Out in the sticks of Essex, I've moved from BT landline internet to Three.

My Speeds went from 15/1 Mbps to 35/15 Mbps. Price from £44 down to £24.

Three do unlimited data contracts.

I can see 5G, if rolled out to all their towers seriously compleating with landlines. If I was on EE here I would get 96Mbps down, as their tower is on a later LTE generation than the Three tower.

Then the cartel price fixing started, flash price rocketed and HDD crept up in capacity to keep us all in the past just a little bit longer.

For storage space, SSDs are already king at over 30TB. It's just the artificially inflated $GB that's saved HDDs so far.
