Re: I must be cutting down.
We still have an establishment like that in Derby, R F Potts (Bob's to most of us).
Wonderful place and worse than Maplin's for great stuff. Even the Maplin's in Derby refers people to Bob's if they don't have it.
Re: Seems amazingly cheap
Just done a quick check on Space.com and it reports that the money is to start the planning process for a mission that may launch in 2025. The final cost for such a mission would probably come in at about 40 Billion over 10 years.
This just the start
I think this fantasticly exciting. If we can put a signal into a nerve imagine an electronic bypass system that reconnects a broken spinal column.
If I was a tetraplegic I would voulunteer for experiments like a flash. Even it didn't work it would be valuable to know and an honour to take part.
I may have made some bad decisions recently...
I hear there's a spacecraft bound for Jupiter needing a computer..
Re: Harvesting spare static electricity
The piezo electric method could be the way using the motion of a blink. This would compress the circuit regularly, generating a smidgin of power and a capacitor in the circuit could store and smooth the power pulse into a current.
Re: Hello doctors
+1 for the "Man of Steel, Woman of Kleenex" ref. I laughed till I cried when I first read that. If you want a real mad experience try reading it aloud to an audience, as good as anything by Mr B Connerly...
Re: iWatch ? I cannot believe
Wristwatches came in because pulling a pocket watch was too much hassle in a busy environment. Pulling a phone out my pocket is just as inconvienent when I'm busy and I think a lot of people find that. I don't use a chonograph (not even digital), just a plain "old-school" watch that shows the date as well as time. Much more convienient than fumbling in my pocket and pressing buttons to find out the time or date.
As for "tech-watches", not my cup of tea but who knows.
Re: we'd use far more energy getting there and back
As usual, Arther C Clarke got in there first, Check out his seventies novel "Imperial Earth" where the plot hinges on the 22nd Century economy of Titan supplying Methane across the Solar System for spacecraft propellant.
Re: Desperate for attention
Their spacecraft is in Lunar orbit right now. They had said that they would be attempting a landing today.
Re: Moving South
Iceland sits at the "pivot point" of the Mid Atlantic ridge, the line of tectonic sea floor spreading that's pushing America away from Africa and Europe. Esentially Iceland is being split apart so it's volcanoes are being caused by a different mechanism.
To get an idea of what's happening have a look at this;
Re: 50 things to do before you die...
Shouldn't that be "SHORTED"?

ClarisWorks - God! I would love to have that back!
It may not have been as well featured as Office but it had enough to make it very useful and it's integration between the tools was so sweet.
I want it back, as it was, right now!
BTW Claris Homepage was quite sweet too. Definately needed to be updated but very usable.
Patience Grasshopper, patience...
I made a nice little one out of a 35 mm film pot once. Pin hole in the base and a tracing paper screen across the open top, projected a lovely little image onto the screen. Nicely ironic too.
However, top marks to this bloke. A little pricey perhaps but it is getting the idea of 3D printing out there to another bunch of people.
Re: They have to call the colony ship "Ark Fleet Ship B"
What was that, a faulty spacesuit? Too bad, got to clean it out now.
Re: I'm surprised
Probably the best beer in the Solar System?
It may not be too spectacular an image but it's absolutely bloody brilliant that we have taken these images from a spacecraft, orbiting another world.
Bit of a traffic jam
After making a fix on the software, Cygnus' controllers were asked to delay the next attempt to dock up until after the Soyuz docking had taken place. If they hadn't both of the vehicles would have arrived at the station about the same time.
Barnes Wallis would be proud of you all, geodetic structure and a Swallow wing plan - brilliant!
I had to watch the video without sound so you may have answered this already. When you test fly Vulture 2 will it be under radio control or are you going to try the autopilot? (or both even)
Re: Small launcher space port - Thunderbirds are go!
But (as has been said before when we discussed Skylon) Britain is in the wrong place on the globe. If we want to launch to equatorial orbits we have to launch over Europe, not good for dropping stages or other problems. Our best option is Ascension Island, slap on the equator and a couple of thousand miles of sea before you hit Africa.
Re: I've ordered a 5C
Skoda seems to be more reliable at the moment...
Re: They just don't build 'em like they used to.
With respect, they still can build'em. There is a rover on Mars that was supposed to only work for 3 months, it's now in it's twelth year.
We got to see this flying!
Michelangelo said "Every block of stone has a statue inside it and it is the task of the sculptor to discover it."
Now it seems to be literally true (although in plastic!).
Well done to all concerned, this is proving to be fascinating.
Re: Originals were great?
Just a little?!
Re: Maybe Crewman Daniels was shot backwards in time again?
Funny you should mention Star Trek, in 1980 there was a "Star Trek Maps" set published which included a navigation booklet. This discussed using pulsars and quasars as triangulation beacons for navigation, quasars becourse these were so far away that they would appear "fixed" on the sky compared to pulsars which are nearer and so would have a detectable proper motion. The manual even gave the equations you could use to plot your position in space!
My set are nicely tucked away in an envelope in my attic 8-)
Re: If he's an expert...
A good idea but complicated by the environmental considerations.
An example. The two Voyager probes to the outer planets (and beyond) were based on the design of the highly successful Mariner series of probes used in the sixties, in fact the the Voyagers were once known as Mariner Jupiter. The main similarities were the basic spacecraft frame, then the changes started to make the craft so different that they were given a new name. The main differences were because of the fact that the craft needed to operate so far away from the Earth and the Sun and the Jovian radiation environment.
The design of Curiosity could be used as a starting point but would have to be altered substantially for the Jovian/Europan environment. Cold would be a major problem, for example. Mars may be a cold place but the temperature out at Jupiter is extreeme by Martian standards. The Jovian radiation environment, as mentioned in the article, is incredibly severe, any kit built for Mars would have to be rebuilt to withstand this radiation.
Hope this helps.
Good, isn't it?
About time we had a rocketship that looks like a rocketship.
Re: Why bother
Not so limited, perhaps.
I recently bought a new music system and it has DAB as it's default receiver choice. I set it up and it seems to be quite effective. I think it's true to say that more and more HiFi systems are equiped with DAB straight off the bat so we will probably see the same kind of take up that occured with digital TV when Freeview digital tuners became built in to new TVs, a default switchover.
I am aware of the argument that states that the dedicated music system will die out as more music moves on line. I'm not convinced by this, I feel that there will continue to be a demand for seperate music systems as there are quite few people out there who still don't use online music providers or radio for various reasons. I myself still prefer the quality of sound produced by CD's over MP3 (not really explored FLAC yet, a bit inconvenient to use) so for the time being a dedicated music system still has a place in our house.
Yes, most of the US air defence requirement is handled by F16's, and if they feel like projecting a bit more force they also have F15C's. Both are mature aircraft and should be cheaper to run than the F22 (esp. the F16).
Glad someone got in with this observation.
Re: Look at da pwetty lights
OK, pseudo-rocket scientist lecture mode on.
You get the diamond effect when the pressure of the exhaust in rocket and jet engines and the ambient atmospheric pressure do not quite match, the terms are under expanded for ambient pressure lower than exhaust and over expanded for ambient pressure higher than exhaust. The effect is actually a supersonic shockwave and you would hear it a crackling in the engine noise (The engine of a Tornado gives a very good example when it's reheat is engaged).
For a rocket engine nozzle this occurs because the shape of the nozzle has to be optimised for the atmosphric pressure it is operating in. For a rocket designed to go from sea level to vaccuum (as Space Shuttle main engine did) it is neccessary to decide which condition the engine is going to spend most of it's operating time and design the nozzle accordingly.
This means that the engine may not be running at it's most efficient at a certain point in it's flight and for the Shuttle this was at launch, as boosters provided much of the impulse to get the vehicle off the ground and through the thickest part of the atmosphere. When these boosters had been used up and jetisoned the main engines were then operating in a high altitude environment that they were most efficient at.
Looking at the Chinese Long March picture I think we see the same kind of thing, a core stage that will fly to quite high altitude and optimised to fly at this lower atmospheric pressure, being supplimented with booster stages which are optimised to work best at ground level to get the vehicle off the pad and to higher altitude.
Right, pseudo- rocket scientist lecture mode off!
I think this is a reasonable explaination of this phenomena but if anyone can add anything to it I would be interested.
Re: Look at da pwetty lights
Space Shuttle main engines used to show Mach diamonds as well, but you have to look closely - oxy/hydro flames are almost invisible.
Re: But I don't wear a watch either...
I think it depends on what you do as much as personal choice. I like having a watch on my wrist as it is a convienient way for me to keep track of things, I teach and time management in class is very important. It's also good for me when out and about as I don't like getting my phone out in public too much.
Still, one day I'll do a "Peter Fonda", throw it away and ride off (see Easy Rider if you don't know what I'm on about).
Try using glass or carbon as the reinforcment material, works for aircraft radomes. Polyester and nylon fabrics would work too.
The chances of anything coming on Mars...
And what does AManFromMars have to say about this?
The Macintosh LC 475, another pizza box of a desktop machine. I was completely taken by that design when I first saw it.
Oh, that's alright then.
Re: Look out for ice
Would this affect the conductivity at all?
Re: Define "drilling"
Ah, misread article. Point noted.
Re: Define "drilling"
Also, it is worth remembering that the later Apollo flights had core sampling drills with them too.
There are quite a few of us "more mature" readers out here and we don't take kindly to being tarred by this brush (well I don't anyway).
Oy! Less about the age!
Re: Spider Robinson covered this a few years ago
Stephen Baxter has also played with this idea in the "Malifant" series of stories (Space, Time, Origin and Phase Space - especially Phase Space).
Re: Camera watching me, watching them...
Blob of Blu-Tak should do the job well.
Re: The Apple what?
I will agree with Mr Lewis here, I do think this is an indication of the Reg readership. Well, I am going to add some more fuel to the fire. As well as being a faithful follower of El Reg I have also been a subscriber to Which for the last twenty years. Over the years I have found these people quite reliable when they produce tests and comparisons. Ok, I agree that they may not be as technically inclined as the commentards here but that's not their audience. The one thing that keeps cropping up when they they test laptops, desktops, tablets and smartphones is that Apple keeps coming up near the top of their recommendations, if not the top.
It's not all unbridled praise from Which though, they do criticize Apple for a number of points that will be familiar to the Reg readership, particularly cost and upgrade ability of the recent consumer items. But it is noticeable that Apple kit fares well in their direct comparisons of kit.
As a whole though it does tend to recommend Apple products to a wider audience than the Reg readers, an audience that may be looking for a simpler experience with their computing kit and may not have a problem about such ideas as a "walled garden" (in fact they may even appreciate it as means of providing a level of security for their devices).
Now, I can see the reaction to this already. "Which are Apple shills/apologists", etc. Knowing the Consumer Association (the organisation that produces Which) I don't think so, they are fiercely independent and brook no nonsense when it comes to that kind of thing.
My position on this?
Neutrality with regard to tech, I have to work with Windows, Apple and Ubuntu boxes and I can see the ups and downs of all three platforms (but that's another post...). But, as I said, I do find Which to be reliable, I have used a lot of their recommendations when buying washing machines, TVs, DVD recorders and other stuff over the years and have not been disappointed (I have also taken their switching services advice and am quite happy with it). So I cannot ignore their comments over Apple.
If you want to call me a Which shill, that's ok, I've done well by them over the years.
