Re: Too much willy waving here
I don't think the unsuccessful launch is a such a big deal to us here, although the Virgin share price is now on a similar trajectory to the rocket.
The "historic" part of it is a silly stunt.

It's a bit of a stretch to claim the launch is from British soil, when the first part is simply transporting the rocket to it's actual launch site over the Atlantic.
It’s using the Boeing as a first stage. Just like launches from Florida use a rocket as a first stage and then somewhere over the Atlantic it drops the first stage and then another booster actually takes the payload to orbit.
But this is just a team from the US using a runway in Cornwall for no actual pragmatic reason than a bit of flag waving.
The first Black Arrow satellite launch attempt failed on a second stage problem, but they were ready to go again and successful within 2 months. I wonder if Virgin Orbit will be back for another go so quickly.
Virgin Orbit are planning on doing a similar stunt in Brazil and another in Australia so I am starting to feel like this is a travelling circus act.
On the live stream it was fairly obvious something was wrong as around the end of the 2nd stage first burn and the start of the coasting phase, the telemetry showed it hadn’t reached orbital velocity, the altitude went down rapidly and it decelerated. It stopped showing descent and went to zero mph at 244,500 feet, presumably when it broke up. It took them 25 minutes after this to announce there was anomaly.
The live stream before that was off the scale bullshit with random Americans spewing disingenuous platitudes and Richard Branson wittering on about when the Virgin Records label signed the Rolling Stones.
I think it’s for taking photos.
I must admit I have a CCD eyepiece and a goto mount, and a carefully fettled Raspberry Pi so I can observe indoors on a 65 inch TV. Because the clearest nights are the coldest nights. Loads of people use setups like this, the idea is far from new. You can share near live images on the web. It’s not like astronomers are lesser astronomers because they book an observation from a robotic telescope on a mountain top in Tenerife or South America and collect their image next morning.
But Saturn just looks the same as the first time you saw it, and Jupiter, changes a bit and its Galilean satellites move about. Mars is very consistent . Nebulae don’t change much. Galaxies are fairly inert. The real variables are the observation conditions and the opportunities plus the occasional cometary visitor.
I have a connected car app/account and it is so secure that I can’t get into it myself.
It sends a code to the car which appears on the screen and it won’t work unless I put that code in and I can’t be bothered to do it again. So it just locks me out.
It was sort of useful if I couldn’t remember locking the car I could quickly check, but not that big a deal.
An aircraft on autopilot will follow the flight plan and land itself if it's in approach mode.
You are getting confused, most autopilots on GA aircraft are height and heading hold systems, or just heading hold. I use one, I tell it what heading I want, and I have to calculate the wind offset to obtain the track I want. There is no FMS for me to input a flight plan and no chance of it flying an ILS. But it is most definitely an autopilot, manufactured by Bendix/King.
If you want to fly an automatic approach and landing then you need a cat 3 autoland system, not an autopilot, and you need to be landing on a cat 3 equipped runway. This is done for low visibility situations and in most cases the first officer will hand fly the flare and landing.
is that if the driver is supposed to be alert and with their hands on the wheel .... why can't they just drive it instead?!?
Have you tried it? In some circumstances it really does help with long drives, the precise lane keeping and steady distance keeping is lifted from you leaving you to just watch for hazards and monitor the other traffic.
I just find it unusable when the road is busy because the actions of other drivers are constantly affecting it.
I also predict that hardware people will extend RISC V implementations in a proprietary way in attempts to get a performance / market advantage.
This may lead to fragmentation that holds RISC V back, or if one comes to dominate then it will surpass ARM but put us back to square one with the proprietary ownership.
I have my second EV, it’s not a Tesla and it was expensive. But I haven’t got it for the economics, that is not the first consideration, I know it would be cheaper to drive an old fashioned petrol car. There is no economic justification claimed.
But there’s no way on Earth I would ever willingly go back to driving an old fashioned ICE powered car, the EV experience is just so much better for me. I also like that my engine isn’t adding to local air pollution.
The problem for Tesla is that there are better alternatives now, and the alternatives are improving still faster. When I was buying the first EV years ago, I considered Tesla but found better. For my next EV car, didn’t even consider Tesla.
It's the classic Trump approach to business - refuse to pay bills and hope the creditors go bust before they can get you to court.
It will be the appointed receiver taking them to court. Does the same thing happen with chapter 11? I would assume so.
Anyway, a business that operated that way should have some difficulty finding suppliers willing to work with them.
The AA and other breakdown services carry portable chargers that can add approx 7.5 miles of range in 15 minutes.
However, the portable chargers packs that you can buy are considerably more expensive and heavier than a petrol container. They are on wheely wheels with a handle like luggage.
I'm going to have a look to see if there are enough decimal places on my calculator to see how much mass would need to be removed from the moon and transferred to earth to make a meaningful difference to the moon's orbital period and semi minor axis compared to how it is already changing by tonnes per day.
I sometimes enter my login details for certain services and receive a text message saying that someone has just logged into my account in z location.
Though it’s obviously me, x location is sometimes 200 miles away. ISP has a big old network and chooses to break me out of their network to the public internet somewhere random.
