This is an excellent demonstration of why we need to further our space travel. It may seem trivial, but to get real advancements in space require people there. Theory is nice and all, but there's so much to learn from practice.
A better example of what I'm saying is thrust. There are plenty of people on the ground theorizing about the bigger and better thrust systems. There are some neat ideas. People would be able to work through them faster by actually being there, and not only doing the specified projects, but their personal pet projects. For example, someone may discover that a windmill style device for turning solar winds into usable energy, and cosmic could be converted into some usable fuel.
A cup is something. It's an example of what can be done from interest or necessity. Something that we're rapidly abandoning, as we watch manned space travel dwindle down to nothing.

What would it be like if we had multiple generations of spacecraft, and real space based societies?
Antarctica has a population in the thousands during the winter. Space? The most I could find was 13. That's not a huge population for a space faring population. That's a camping trip, without the woods. To put it in comparison, 0.0000002% of the world population was in space at the same time. Once.
No one does fun little experiments like "What happens if you space a water balloon?". There are important things to know, and until more people are up there doing oddball experiments, we won't discover 'em.
And, I'm all for spacing a water balloon. A thermite filled balloon launched towards the atmosphere should make a pretty light show. It might need to be a pretty big balloon. Lots of room to experiment. :)

In the end we really have only one choice, and that is stay on the course NASA is on and concentrate on probes. Sure we can bum rides with the Russians but that is only a band aid as their tech is getting long in the tooth too (Soyuz is what? 40+ years old?) and all it will take is a few more massive fails and they may end up grounded for good. So our only real choice is to continue to get the absolute most bang for the buck we can and that is small and light probes we can launch on Atlas and Delta rockets. Maybe if we had a congress that gave a shit about the country as a whole instead of their own enrichment we might actually be able to do something, but what are the odds of that happening?

Similar to my work pattern... by gwolf · 2012-02-25 18:56 · Score: 2

I usually get a cup of coffee every 60-90 minutes. Do I get to be an astronaut?

Watching that video made me want to be an astronaut again. Haven't felt that way in a long time. We need cheap, publicly available space flight in the next 50 years or I'm gonna be very disappointed.

Why? Why do we *need* it? As entertainement for bored, rich, white middle-aged men? We don't even have supersonic passenger transport right here in Earth, where there are destinations at *both* ends, but it's vitally important to go into a total, deadly vacuum? Why? Do you ever question your assumptions, or why you have such peculiar beliefs?

What they're not telling you is that before coffee, they experimented with Red Bull. It turns out it gives you wings but despite being in a compressed air microgravity environment, the whole equal and opposite reaction thing messed up the flight too much.

Food in space... by freeze128 · 2012-02-25 20:20 · Score: 0

Astronaut Don Pettit recently downlinked a video that shows him slurping coffee from a cup he kludged out of plastic sheet.

Astronaut Don Knotts has proved that it is also possible to eat peanut butter and crackers while in a microgravity environment.

Is that cooffee? by Anonymous Coward · 2012-02-25 21:04 · Score: 0

Seriously, if that transparen slightly brown liquid that looks like watered down sewage water is what goes for coffee in space, then I'm not going. Unless I can bring my own supply of coffe beans, a grinder and a proper moca-brewer.

Your beans will be fine, but I bet all commercially available grinders and brewers fail abjectly in microgravity. French press is probably the easiest to make work, with the addition of a spigot and an air bladder for "pouring".

Terrible waste by optimism · 2012-02-25 22:44 · Score: 1

This just reinforces what a waste of time and money the current space program is. Yeah, it is somewhat inspirational to have humans up there at all. But terribly impractical.

In the 20th century, humans were the most compact computers & manipulators for these missions. But that is no longer the case.

It's ironic that we send people up for near-earth-orbit missions (which could be controlled from the ground with sub-second latency), while we send robots on the long missions (which would benefit most from a short-latency human controller in the vehicle).

We should put our resources into manned long missions (asteroid or mars) instead of the ISS boondoggle. And give those astronauts practical round straws, not funky knife-edged cups, for their drinks.

If you're interested in modeling this phenomenon you can do so using the Laplace-Young equation: http://en.wikipedia.org/wiki/Young%E2%80%93Laplace_equation

I did part of my Master's thesis using it... for some examples see here: http://www.cfdlab.ae.utexas.edu/labstaff/carey/GFC_Papers/Carey216.pdf
