    • ah I have to disagree here. these guys aren't thrill-seekers to my mind. Instead they aer expanders of frontiers. And i say that if nasa isn't going to open up the frontier to the rest of us the way the west was opened up in the 1800s then we should open it ourselves. also the coast guard responds to rescues of private sailing vessels at sea. these are small ships. thats not thrill seeking? I live in a port community and some of the vessels I've seen leave our waters leave a lot to be desired in terms of seaworthiness. the coast guard can pick them up so why shouldn't they pick up some folks that are trying to make life on earth fun? personally I hope they succeed and have a helluva lot of fun doing it.

      Although I doubt they'd be able to sleep. That's crazy to think they could be falling and just fall to sleep. They need some sort of board to lay on that will keep them from flipping around while falling.

        This could be done with a small stabilizing chute. It was used in the legendary Kittinger jump (Project Excelsior). This guy was jumping from 19 1/2 miles up, and 16seconds from jump time a small stabilizer chute would automatically open to stop spinning. Tests with Dummys back then have shown that an aerodynamically unstable object like a human can easily hit 200rpm in free fall. 140rpm for a minute are considered fatal.

        Oh, and if you are tired, remember it will be short nap - 19 miles are crossed in less than 14 minutes.

        I don't know if I'm just unconventional here, but I always thought that parachuting from an extremely *small* altitude would be more nerveracking. At least more so than a 20 minute free fall.
    • Do you think they are unaware of these things?

      A large enough balloon, and it's no problem.

      From what I've seen, HUGE partially-inflated balloones are used.. they can go fro looking more like a giant upsidedown condom to a really huge round balloon.

      As for the parachute.. of course you take one. Thing is.. you don't open it for a long, long time. At that altitude, if you opened a chute, it wouldn't help one little bit.. it would fall at the same rate as you.

  • We intend to fly QinetiQ 1 on a clear day, enabling people to see it with the naked eye from up to 600 miles away. Potentially several hundred million people will witness the flight as a live event.
    So if the thing is as high as the Empire State Building (~1400ft), is it still likely to be visible from 600 miles away? Somehow I doubt it - that's like standing on top of the Sears Towers and seeing the Empire State Building!
    • The sun is bright and something that big makes an excellent reflector. Once it gets up and there isn't so much atmosphere between it and people viewing from farther away it could be quite visible. Have you ever seen a far-distant airplane glinting in the sun?

      I think you are right, but your analogy isn't really fair. One reason you can't see the Empire State building from the Sears tower is that Earth is in the way. (Earth is roughly spherical, remember?).

      The other problem with viewing objects near the surface of Earth is that when you look horizontally, you are looking through relatively dirty air. The problem is much less severe when looking up, because the air rapidly clears and thins as you ascend.

      What we need to know is how bright is this thing going to be and what angle does it subtend from 600 miles away? A bright object can subtend a small angle (think supernova) and be visible, and an object which subtends a large angle can be dim, yet still be seen. I believe the moon and sun subtend about 30 minutes of arc, so I imagine anything that subtends, say, half a minute of arc would be considered visible (this is a guess) although if there were poor contrast (i.e., if the object is sky-colored), this wouldn't hold true.

      At 600 miles, 0.5 minute of arc is approximately 460 feet. I couldn't read the article so I have no idea how big this baloon is, but I doubt it is 460 feet in any dimension. So to be visible at 600 miles, I think it would have to be bright (e.g., if it were low in the eastern horizon while the sun was setting, it might be quite bright.)

        The QinetiQ 1 balloon will be the biggest manned balloon in history several times over. Made from polyethylene, it will have a volume of more than 40 million cubic feet at 132,000 feet - about 400 times the size of a typical hot air balloon. At launch, the top of the QinetiQ 1 balloon will be seven times higher than Nelson's Column and as high as the Empire State Building.

Coincidentally, 600 miles is 966 km so I saw it from at least 600 miles away as I watched it nearly from horizon to horizon.

  • Maybe there is a reason no one has tried this since 1961... No oxygen, Minus 100 degrees Fahrenheit. Good thing the ballon doesn't have to worry about re-entry. Next thing you know, they'll want to take a money up with them, to "see how it copes with the conditions".

    I wouldn't discount this as a hairbrain idea from some thrill seekers. If you look at the cost of launching any payloads to that altitude, it makes the cost of specialized ballons look a lot better. I'm not sure what the use of getting people up there is, but as stated in the post, there isn't much atmosphere above you and hence not much turbulance, so things like short, month-long telescope missions and other scientific observation could be done much cheaper.

    OK. Just some crazy thinking...

    Did you guys see this picture:

    http://www.qinetiq1.com/gfx/large_balloon.jpg

    That is a HUGE balloon!

    Now here is my thinking...

    Remember the Hindenburg? (sp?)

    What if this actually worked and on the next attempt they fill the balloon with Hydrogen?

    If they built a special gandola which was a SMALL spacecraft, they could use the hydrogen from the balloon as fuel and possible exit the earths orbit.

    Would this work? I don't have access to any of the math behind this so someone with experience could help.

    ... and we all know that everyone on Slashdot is a Rocket Scientist!
    • the amount of hydrogen in the ballon is very little when compared to the amount of hydrogen stored in liquid form in a rocket normally. Though you're higher, I can't heplp but feel that you wouldn't have enough fuel - maybe as a tiny supplement, but it still seems like it'd be like a drop in the ocean.
    • For every 1 kilo of Hydrogen you burn, you need 8 kilos of Oxygen. Where do you get it?

      You can't carry it as payload, obviously, because when you multiply the weight by 9 you no longer have a lighter-than-air craft.

      So, you have to rely on ambient oxygen. And there just isn't enough at that altitude.

      Nice idea, though. Pity about those pesky laws of physics.
    • That is a HUGE balloon!

      That's because there's SO little pressure at that altitude. It's nowhere near as big with the same mass of gas at a lower altitude, but the higher you get, the more volume the gas takes up, hence the huge volume at the top of their trip.

    • SPECULATION WARNING!!!

      OK. No maths behind this either but... Hydrogen under atmospheric pressure is not a great fuel in terms of rocket boosting. So we need to do something to put some pressure into that baloon - but remember, the more pressure the more density the less bouancy so the less lift - so we need to apply the pressure once we're up there.

      We also need to apply it quickly - so we dont drop like a stone.

      We also need some oxygen to burn with the H2 - not much of that up there... so we need to carry that too. Unless...

      Unless we don't bother burning it we just 'untie the balloon' and let the H2 squirt out in a controlled manner...

      We'll have 1 atmosphere pressure in the balloon, and 1/10th atmosphere outside so we have 9/10 atmosphere of pressure. So we need to work out the thrust that that can be turned into.

      This is useless, but I'll post anyway in the good slashdot tradition!

    Nice, but 132000 feet is only 25 miles, just half of what USAF awards astronaut wings for (50 miles, and some X-15 pilots earned them). Even less than half of the 100 km that the International Aeronautical Federation considers the edge of space.

    Still, it sounds like a fun ride!
    • The best part of the Air Force Astronaut program was that only the Air Force X-15 pilots got the wings. The civilian test pilots didn't.

      The Air Force guys felt bad for them, so they organized a party where they presented the civilians with cardboard wings bearing the title 'Asstronaut'.
  • Two ballooners are going to attempt to get to 132,000 feet in a helium balloon named QinetiQ1. They are going to do this wearing spacesuits and sit in what looks like armchairs in an open gondola

    Why does this story sound eerily like an acid trip?

    Stoner 2: "And also we were wearing these really really shiny spacesuits man."

    I was wondering if at that height they'd be floating about with or without a balloon due to lack of gravity. This is from the site:

    It is a popular myth that weightlessness is caused by the lack of gravity in space. In fact, the apparent weightlessness is a consequence of astronauts and their surroundings all moving together without resisting gravity. Satellites and spacecraft are still subject to gravity, but because they are moving fast enough horizontally, gravity pulls their path into a circle or orbit. The balloon itself will float with the wind and will travel at no more than 10-15 mph in an upward or downward direction. So the weight of the pilots will not be affected by the height they reach.

    I can just about buy the bit about spacecraft, centrifugal forces or whatnot, but I'm still trying to figure out if they're trying to imply that these balloonists will have sea-level like weight at that height. Anyone?

    Anyone know how 'high' you've got to get before you do float about because of a lack of gravity (oh my, what have I asked ;-)
    • It depends on the distance to the earth's center of mass. Double the distance from the center of the earth, and you'll quarter your effective weight. Since the radius of the earth is roughly 3960 miles, and these guys are planning on going to about 26 miles up, they're going to weigh 98% of what they do on earth.

      Talk about ultra slim-fast. Not much of an effect, really.
    • by jerde ( 23294 )
      Awfully, awfully high. The radius of the earth is, what, 4000 miles.

      Force due to gravity varies inversely with the square of the distance.

      So what's the difference in gravitational force from being at sea level, 4000 miles from the center of the earth, to 132000 feet, 4025 miles from the center of the earth?

      4000^2 / 4025^2 gives me around 98%. So I'd weigh a few pounds less at that altitude.

      To weigh only half as much, you'd have to be about 1700 miles above the surface, or about 9 million feet.

      Earth big.

      Of course, by the time you get 250,000 miles away (like the moon) you'd feel less than 0.03% as much gravity from earth.

      And keep in mind that all of this assumes you are STATIONARY in relation to a point on the earth's surface. If you're orbiting, you don't feel gravity.

      - Peter
    • They will have VERY close to sea level weight at that altitude.

      Don't think of weightlesness as being "away from the influence of gravity", instead think of it as being "in freefall" i.e. not resisting gravity but rather just falling with it.

      Astronauts in earth orbit feel weightless, even though they are still subject to (almost) 100% of earth's gravity. Why? Because instead of resisting gravity (by standing on an immovable surface), they are just letting themselves free fall under the influence of gravity.

      A circular or elliptical orbit may not obviously seem like freefall, but it is if you look at the vectors. If you superimpose centripetal acceleration (towards the center of the earth due to gravity) on top of just the right tangential translational velocity (orbital speed), you get a constantly curving path, that parallels the curvature of the earth. That's an orbit.

      The reason the astronauts feel weightless and yet the baloonatics feel whightfull(?) is that the baloonatics are resisting gravity, rather than freefalling with it. If you could hypothetically accelerate the baloonatics to just the right orbital speed, in a direction tangential to the earth's curvature, they would be in orbit, and would be weightless.
      • Nitpicking my own earlier post...

      Y'know, this is high school physics. (Or ought to be; it was when I was a teenager.) You never float about because of a "lack of gravity." Similarly, you don't really need gravity to plant your feet firmly on the ground. What you need is acceleration. The force that supplies this acceleration is irrelevant to the effect. In the neighborhood of a massive body like the Earth, the force of gravity provides it. On orbit, an astronaut floats around not because there's no gravity -- there obviously is; that's why his spacecraft is orbiting instead of flying away -- but because his entire frame of reference, including the floor he would otherwise be standing on, is being accelerated at the same rate towards the center of the Earth. The craft remains in orbit instead of falling because it begins with enough "horizontal" velocity to "miss" the earth by the radius of the orbit, to put it in the simplest possible terms. Orbits decay when something acts on the "horizontal" velocity to decrease it. That's why the best way to achieve re-entry isn't to aim your vehicle at the earth, but to slow it down. Eventually, it slows down enough so that it no longer "misses". Vehicles in low orbits can have their orbits decay from the very small amount of air resistance due to the tenuous upper atmosphere they're within. Lacking air resistance or some other kind of force to slow it down, a vehicle can stay in orbit indefinitely.

      Horizontal is in quotes above because it's not quite the right word. More properly, it's a velocity vector normal (or perpendicular) to the acceleration vector. Since the direction of the acceleration vector keeps changing as the position of the vehicle changes, the velocity vector keeps changing too -- as it must; there's an acceleration acting on it. The equations to compute the initial velocity needed to keep a vehicle in orbit at a particular altitude are not complex.

      This is exactly the same physics that keeps the Earth orbiting the Sun and the Moon orbiting the Earth, just on a smaller scale.

      The writers of Star Trek never understood how this worked. In TOS there were a number of episodes where the engines had been damaged or sabotaged and the orbit was somehow rapidly decaying. Only a moron would have put them into such a low orbit that it needed constant thrust from the engines to maintain it in the first place.

      "Weightlessness" is also achievable by falling at the same acceleration imposed by the force of gravity. For the Earth, that's about 9.8 m/sec^2. Astronauts train at weightlessness for brief periods by doing just that -- they get into a specially modified cargo plane, fly up as high as it will go, then pull into a steep dive. They float around inside the plane just as they would on orbit for as long as the dive lasts.

      The balloon will never be travelling anywhere near fast enought for any of this to occur.

    Terminal Velocity [wired.com] talks about Cheryl Stears (U.S.) and Rodd Millner (Australia) who are both going for a record skydiving attempt from 130,000 feet. It looks like QinetiQ is going for altitude. Millner and Stearns are going for altitude and extreme gravitational acceleration.

    This does not really strike me as a major aeronautical achievement.

    Col. Kittinger did a 102,800ft rise in a balloon back in the early 60s (Project "Man high"). The thing that makes this ballon trip unforgettable to history (at least for me and at least until somebody pushes the limit) is the fact that he opened up the gondola he was hanging in to throw himself out into the hands of gravity for 18 1/2 miles.

    You can read up on it here [tsixroads.com] and here [africanextreme.co.za]
  • ... you look down on whole countries in one go.

    Whole countries? Liechtenstein [odci.gov] or Vatican City [odci.gov]: easy. Russia [odci.gov] or Canada [odci.gov]: not so easy. :-)

  • The best time and place to do this would be over Australia on November the 18th!

    Whatta show with meteorites coming down all over the place.
  • ...and says to the security guard, "What's up with the big Q's"?

    LOL...or something
  • Man, abuse that. Take two people up and some super soakers [supersoaker.com]. With the increased pressure in the cannisters, and very little wind resistance, those babies should go for miles.
    Wait, why not take up a couple of colt revolvers [colt.com] and some afghans. Did I type that out loud?


  • Darwin award anyone?
  • Now hopefully these guys will avoid painting their balloon with aluminum powder...
  • Look, people, it even says in the story that QuinetiQ used to be DERA. For those who don't know, I'll spell it out, Defense Evaluation and Research Agency. This may be a civillian do, but it is a government project. Why? Replace "132000 feet" with "well beyond the maximum altitude for any current or projected missile system" and it makes more sense. The latest rumour down the grapevine says that this is an AWACS replacement. You lose the turbulence and engine noise that requires lots of fancy signal processing to get around, you lose the cost of the airframe. Current AWACS are low, slow and expensive, a perfect target which is why you can never take them near the front line where they are really needed. Whilst these balloons will need set up in advance, they can cover whole countries at once whilst still being in conventional radio range, unlike satellites.
  • Yeah.. from what I read and saw in this morning Metro, the 'astronauts' didn't have any kind of parachute.. and they actually sit _on top_ of their 'shuttle' strapped to the bottom of this huge ballon..

    Not that i've actually done this myself, but strapping yourself to the top of what looks like a dingy and going up to 130,000+ft in the air - surely that's a recipe for some white-knuckle turbulence?

    Something I saw once on TV from one of these transatlantic balloon flights.. Concord flew a couple of thousand feet above them and the sonic boom/shockwaves made the cabin attached to the ballon literally jump up into the ballon and then back down again (lucky the string didn't snap!).. That'd be one hell of a ride in this ride-on-ballon....
  • Some background on QinetiQ: The Defence Evaluation and Research Agency (DERA) in the United Kingdon, became the company QinetiQ on 1st July 2001 The company is a Public Private Partnership and is currently owned by the MOD (Ministry of Defence). Our current research areas include: Space, Aeronautics, Radio comms, Satilite comms, radar, balistics, computer security research, and many, many more areas.

    For the real scoop...

    Go to the Sun (UK) newspapar.

    The article is here... [thesun.co.uk]

    Packed with insightful scientific observarions such as:

    "Their vast balloon -- 400 times bigger than normal ones -- should be visible from the ground as it ascends."

    and I am sure some one else has explaind why but I am going to throw mine in also.

    the helium will not be able to stay dense enough at higher altitudes to be able to give proper lift. there is a practicle limit on ballon travel.
    • Uh?!

      Ballons float because they (the ballon, the pilots, the gondola, everything that is tied together) are less dense than the atmosphere at the ground and are the same density as the atmosphere at their ceiling.

      Helium does not need to stay "dense" to provide some lift. The less dense it is the better.
    • It's the air outside the balloon that won't be dense enough to support the balloon. At some point the volume of helium needed to provide the lift is going to be so large that the weight of the envelope is going to exceed the boyancy provided by the volume it encloses.
  • Hey math person, post a link to mapquest from the perspective of this ballon, using the zoom in/out feature. say from over NYC or something. then we can all click it and see what these people would be able to see. thanks math person!

    I read about this elsewhere, and that little snippit unfortunately leaves out the interesting bit.

    One of the points of this journey is to become the first people to break the sound barrier without a vehicle. Their top speed will be upwards of 900MPH on the way down, due to the vastly reduced air resistance. Seriously, think about creating a sonic boom with just your own body...
