Video: Gigantic balloon to lift tourists into space

By | August 19, 2011, 5:58 AM PDT

Space agencies like NASA deserve plenty of credit for taking human exploration further than it’s ever been. But at the same time I’ve always felt they’ve unintentionally created the false impression that space travel requires all kinds of elaborate technology like rocket boosters and sophisticated shuttle equipment. Now a little-known start-up is poised to show that a trip to the heavens can be as simple as hitching a ride on a balloon.

Zero2infinity’s helium-filled aircraft, the Bloon, is designed to lift passengers to an altitude of 22 miles where they can cruise around the earth’s upper atmosphere. Granted, such a short distance isn’t high enough for feelings of weightlessness to be easily induced as they are on the International Space Station. For perspective, the orbiting space station is located 220 miles away, where conditions are much more ideal to create such an environment.

Still, the elevation should enable tourists to see the curvature of the earth and take in panoramic views of other celestial bodies. Essentially, it’ll be enough for them to get that “hey! I’m in outer space” feeling, even though in actuality they’ll be floating in a region just below that known as “near-space.”

Reaching the destination point will only take about an hour and passengers will have the peace of mind that the journey is emissions-free since the contraption isn’t powered by rocket fuel or other environmentally-unfriendly energy sources. For interested businesses, the company also touts other benefits such as the absence of noise pollution and costly infrastructure.

The balloon’s dimensions provides a sense of just how much helium is needed to levitate a pod carrying six people. The balloon itself measures 423 feet by 316 feet, while the passenger housing is roughly 13.7 feet in diameter.

The notion of ascending into space using helium balloons is actually a fairly old idea. In fact, before rocket ships, humans relied on them to rise above the clouds. One of the most famous examples of a helium-powered near-space journey was made back in 1960 by Joe Kittenger, who soared to an elevation of 20 miles before he jumped off and parachuted back down to earth to claim the world’s record for the highest jump ever.

Here’s what it looked like:

For guests aboard the Bloon, the return to terrestrial ground won’t be as death-defying. After cruising around for a couple of hours, the module will begin its fall by releasing helium from the sail end. A parachute will be deployed during the last 30 minutes of the home-bound journey. Before landing, eight vented airbags at the bottom of the pod will activate to cushion the impact.

Zero2infinity has tested an unmanned prototype that reached an altitude of 20 miles and has completed  an initial round of venture funding (Series A) and plans to put the airship into operation in 2013 at the earliest. The company’s says interested tourists can book a spot ahead of time by registering on the site. Tickets aboard the Bloon start at $156,000 dollars.

There is, however, one major potential roadblock. Helium is a limited non-renewable resource which so happens to be in high demand from manufacturers of superconductors to medical devices. And experts estimate that the world will run out of helium within 25 years, an impending shortage that may be enough of a obstacle to pop Zero2infinity’s balloon (no pun intended).

We’ll have to wait and see over the next few years of this idea ever gets off the ground.

Author’s note: The post was amended to state more accurately that the balloon doesn’t go high enough where conditions would be ideal to create a zero-g environment. The International Space Station, for instance, is high enough where the effects of atmospheric drag on it’s orbit can be easily mitigated.

Why stop at 22 miles?
Use the balloon to get started, and then continue using a booster: Of course it requires hydrogen. Please see www.h2liftship.com

Why release the helium?
Instead of venting the helium to descend, why couldn't it be compressed back into tanks in a controlled fashion to reduce buoyancy and lower the vessel? That would preserve the helium for reuse as well as provide a better means of control very similar to hot air balloons turning on the heat when needed for a controlled landing.

Probably because of weight.
Recompressing that much Helium would require a sizable compression unit, the fuel to run it, and, of course, high-pressure tanks to hold it all. The weight of all of that would likely be a ton or more, meaning the vehicle would barely be able to get off the ground, much less anywhere near the edge of space.

Compression
That's precisely what I wondered when I read the story. Don't vent; compress. Maybe it's a question of the quantities involved and the amount of equipment to compress the gas in a reasonable time. Hmm.

Equipment Weight
I thought of that as well and realized that it would increase the requirements for a bigger balloon and more helium but the savings would be realized on multiple trips for none of the helium would be lost. Sure, it will take more energy to release/compress the helium but I think it would certainly be cost justifiable.

Oh good, it's "carbon free"...
...which I guess is the standard by which we now morally judge any industrial or recreational activity. (But then again, by that standard so was the Space Shuttle, for the most part, as its engines were fueled by hydrogen) Never mind the infrastructure required to launch and retrieve the vehicle, or the massive use of non-renewable Helium.

Not that I wish to be so critical of this venture. Actually, I think it looks pretty cool. But if you're going to throw the "carbon footprint" argument in as a justification, then that's the framework you have to be willing to be criticised under.

Also, achieving "zero-g" is not a function of altitude, but velocity. Once must acquire either a 9.8m/sec vertical deceleration, orbital (horizontal) velocity (dependent upon altitude) or some combination thereof.

Running out of helium!
In 25 years? Oh my gosh, how will I make a squeaky voice at my grandchild's birthday party?

BTW, nothing is ever said about weightlessness in this article. You don't achieve weightlessness, even in the ISS, unless you are perpetually falling toward earth. If the ISS held perfectly steady above the earth the astronauts would still experience gravity. Think about it... the mere fact that the ISS and other satellites are orbiting the earth means that they are experiencing gravity.

Thanks!
Thanks for saying what I was thinking. People just don't realize that if the ISS didn't have a "forward motion" of 17,000 MPH, it would fall like a stone (OK, technically, it IS falling like a stone!). Didn't the author take Physics 101? It's Newton! You just don't get more basic than that! How much do you weigh 220 miles above the Earth's surface? About the same as you do here on the ground!

helium
I see no reason why the balloon cannot have its helium compressed on board to lower its bouyancy rather than venting it other than the loss of perhaps one passenger's weight. a small compressor run on lithium batteries ought to make this possible..and thus the principle of baloon flight can be made "green" and recyclable.

They could use hydrogen
Hydrogen is also a non-renewable resource, but we have oceans of it. And, hydrogen gas is half the mass of helium gas. (Not 1/4th. Hydrogen gas is diatomic; helium isn't.) Another benefit of hydrogen is that occasionally we'll get a spectacular disaster that kills off a dozen mega-rich people.

Actually, Hydrogen is quite renewable...
...as it's the most common element and practically everywhere. Balloonists have been extracting it through chemical processes for nearly 200 years.

$156,000 dollars?
First of all $156,000 dollars reads "one hundred fifty six thousand dollars dollars", but aside from that, doesn't Richard Branson plan to offer sub-orbital flights for about the same price? I guess the Bloon would be for the less adventurous (much more relaxing), but I think for the money, I'd rather go higher and get my wings!

Thinking About Weightlessness
Author Nguyen should realize that the altitude at which at which a vehicle finds itself doesn't necessarily determine the state of weightlessness of the occupants. Even if the "Bloon" COULD somehow rise to the altitude of the ISS, the occupants would NOT be weightless! Rather, they would feel their full wight, less a tiny amount because they are farther from center of the Earth than they would be at the surface. Only if the vehicle somehow achieved orbital velocity would the acceleration due to its being in a circular orbit offset the occupants' weight.

Sorry, Tuan, your amendment is still wrong!
Tuan, Your amendment says: The post was amended to state more accurately that the balloon doesn???t go high enough for passengers to experience the same ???sensation of weightlessness??? caused by microgravity that astronauts feel aboard the International Space Station. Previously, I mistakenly referred to this as zero-G.

Your attempted correction is actually just as misleading as the original because it leaves readers with the impression that gravity really does go down close to zero if the balloon were able to go high enough - e.g. from 22 to 220 miles. Actually the reduction simply due to that change in balloon height (impossible in practice of course!) would be a barely perceptible 9% in body weight.

It is not because "the balloon doesn't go high enough" that the occupants fail to experience the "same sensation of weightlessness" as they would in the ISS. As several of your respondees have already pointed out, the ISS occupants experience weightlessness because of the high angular velocity of the ISS around the earth which causes a centripetal force which exactly balances the force due to gravity at that height. In other words, it is in orbit! In comparison, the balloon, of course, has no (significant) angular velocity around the earth so there is nothing to offset the force of gravity however high or low it goes.

Incidentally, the so-called "microgravity" experienced in the ISS is nothing to do with some vestige left over of the actual gravity at that height. It is simply a (slightly confusing) scientific term describing the situation in an environment when the actual gravitational force is exactly balanced by the centripetal force - i.e. it is indeed a condition of true weightlessness.

Balloons and Project Farside
The USAF used balloons in the late 1950s and 1960s to launch a series of experimental rockets from high above the atmosphere. They called it Project Farside. The goal of the program was to place a payload on the far side of the Moon, which goal was never even approached. http://space.skyrocket.de/doc_lau/farside.htm

Will they be squandering inirreplacable helium?
Helium, being a noble gas, cannot be manufactured; I believe we get it mixed with natural gas. Because it is so light, and leaks escape to space. Since it is so useful for other things, I regard using it for wealthy "tourists" is short sighted and not acceptable.

compressing the gas
The compressor would have to be no more complicated than a high-speed blower filling another envelope inside the big balloon with denser gas.

helium balloon
How about using a hot air/helium hybrid balloon? The temperature differenttial would provide good lift. The hot air balloon could be inside a helium balloon. Therefore you would not need to vent the helium.
