Wonder how much it cost to do this little experiment and who foots the bill?

Can be proven in a lab with a vacuum chamber, but the kids gotta' prove it in space. I'd suggest they ask for two of them to volunteer and see if they could have a nice little chat about how great socialism is after they pop off their space suit helmets just outside of the space station....would make great You-Tube footage.:upeyes:

Don't let physical reality get in the way.


Maybe they should be taught what is a good experiment versus "fun".

What a waste of a rocket.

Will be interesting to see if it's possible to hear screams in space or not, will be fun to try regardless.

You should voluntarily add about $10,000 to your tax bill this year to help fund the effort.

We already know the answer.

Don't worry, Obama is doing that for us. :tongueout:

Not necessarily. We used to think that solar winds didn't exist, but now we know different. Maybe it will also become that we used to think we couldn't hear screams in space, but maybe we actually can. Won't know 100% until we try it.

Given that they launch using a balloon, not that much.

And given that A) Cambridge is in England and B) it's a student society, I'm guessing it's a combination of the British taxpayer and the students' tuition fees.

That's simply not true. We know 100% that sound won't transmit below a certain critical air density.

Sometimes a "fun" experiment to catch public interest isn't a bad idea.

How can a balloon, lighter than air, but heavier than a nothing (vacuum), reach space? Seems like it might get wicked high, but not what is considered "outer space". Think they can hit what is called "near space" 26 miles up or so, but when some one is talking in terms as large as this, "close" is a very relative term.

I should have given a more complete description, sorry.

Your reasoning about the maximum altitude of a balloon is absolutely right.

Rockets are, on some level, an inefficient way of reaching space--they're heaviest at the Earth's surface (because they're full of fuel) which means they have to be huge/expensive in order to be able to lift a meaningful payload into orbit.

Cambridge University Space Flight is experimenting with using a balloon for the initial lift (to the maximum height that a balloon can reach, which is very high) and then firing the rocket after that. The idea is that the balloon lifts the rocket high enough that the rocket doesn't need to be very large. The goal is to get the price tag under 1,000 GBP.

At this point the idea of the experiments is to refine the rocket/balloon system; it's not yet in a state that's useable for real science research. That's why they're doing a fun/silly experiment.

OK...cool idea then. That puts the whole deal in a whole new light that wasn't included in the story I posted. For sure, getting a payload headed in the right direction on the cheap is a big step, and if you can get it to a point where air resistance in minimized then the rocket needed to kick it up to space becomes much smaller and cheaper. Good idea for when they can launch spy satellites the size of golf balls.......if they don't have them all ready!!!:shocked:


Putting my indignation back in the box for a while!:supergrin:
