It is crap like this that caused NASA to begin its shutdown. $400 million per shuttle launch when estimates for a civian run lauch range greatly, but the highest I've seen was around $50 million
The reasons for building a pool to test it in is to have non variable, measureable data. Tossing it in the ocean will introduce a whole other set of extra variances that will be much harder to map and compensate for, especially when trying to test the viability of one material over another. Keep the environment fixed and you are just testing material vs material.

Yes, they will have to test at open sea, but only after they have narrowed the field down to the best possible choice from their fixed tests.

Insufficient or improper testing is the surest way to have ourselves another Challenger or Columbia type disaster.

Im glad NASA are still working on a new project, its freaking criminal that America has to rely on Russia to get them into space!
AM i the only one who has noticed that the capsule they appear to be testing is almost identical to the Apollo capsules??
Couldn't they of used some of the test data from the rigorous testing they performed to perfect the landing of the Apollo capsule......might of saved them a few mil on a mahuuusive pool.....just a thought.

Well the whole idea of Ares/Orion is to take the old Apollo concepts and paradigms and rebuild them with modern technologies and materials. We have lighter, tougher, more durable materials than they had back then; but we also have to test their properties under various conditions, because they behave differently than the materials used in Apollo did.

Exactly so.

100% for sure they dropped various "models" probably of different sizes into pools or whatever before they even got this far.

They test things like this in baby steps. This only made the news cuz it's the first drop of the real craft (test version).

The decision to go back to rockets and capsules is pretty much an economical one.

It ended up being very expensive housing, maintaining and prepping the shuttle fleet, the SRB's, and the fuel tanks. Old fashioned rockets and capsules are cheaper in the long run.

Mankind can only truly progress with a clear understanding of the environment around us.
In the grand scheme of things we are a very insignificant blip on a hugely unexplored canvas.
Exploration is what used to define us as a species, but sadly our thirst for knowledge has been overcome by our thirst for wealth and greed.
As soon as we learn to put our differences aside and work together to explore the universe, the better place the world will be to live in.
We've only really started to scratch the surface of space exploration, there's the possibility of habitation on the moon, terraforming Mars, Titan...the list is endless and most are within our grasp.
Its very disappointing when the negative shallow minded folk seem to think we've learned all we can learn from space and just be happy to live like this forever......there is more to learn from space than i think anyone can truly comprehend.
I really hope NASA can get its new project off the ground (forgive the pun), I truly believe that the space program and further exploration of our galaxy is one of the most important things we should be focusing on.
Just my thoughts on the matter.

As far as this testing goes...the only environment they need to worry about is the capsule its self

This is just more 1960's type of thinking (and spending). $1.7 million could have done a small part in keeping a truely worth while NASA program going.
So trying to create a viable way to get humans into space isn't worthwhile?


A controlled environment is needed to make sure the capsule works BEFORE spending even more money on a recovery vehicle and launch mechanism that would have to be tailor-made to suit the capsule. If it turned out the first iteration of the capsule didn't work, they'd have to throw more money at redesigning/refitting the recovery vehicle etc.


It's true that they will have to make them eventually, but this way they will only have to make them once.


The idea behind scientific experiment is to achieve reliable, repeatable data. Having a controlled test area is a fundamental principle of scientific experiments. What would happen if, say, the capsule hit a trough in the water, overturned and survived its impact only because it hit sideways on, as opposed to straight down? When they repeat the test later, it breaks apart, and now, it's difficult to say what's quite at fault - not noticing the five degree difference in inclination between the two tests.


This is money that needed to be spent to make sure it worked. Missing it out would be cutting corners, and we know where that got them in the past.



I wish it were cheaper, but it's nice to see progress towards further manned space flight.

Exactly. A lot of people say that the space program is a waste of tax payer money but I'm a tax payer and I think space exploration is very important. Plus its a lot more useful then spending billions of dollars a year to arresting marijuana users, if you want to complain about useless spending, that's where you should look
