"Frickin' Fantastic" Launch of NASA's Ares I-X Rocket
coondoggie writes "With a hiss and roar, NASA's Ares I-X rocket blasted into the atmosphere this morning at about 11:33 am EST, taking with it a variety of test equipment and sensors but also high hopes for the future of the US space agency. The short test flight — about 2 minutes — will provide NASA an early opportunity to look at hardware, models, facilities and ground operations associated with the mostly new Ares I launch vehicle. The mission went off without a hitch — 'frickin' fantastic' was how one NASA executive classified it on NASA TV — as the upper stage simulator and first stage separated at approximately 130,000 feet over the Atlantic Ocean. The unpowered simulator splashed down in the ocean."
It may really be the case that the launch was 'frickin fantastic', but just having finished reading Red Moon Rising: Sputnik and the Hidden Rivalries that Ignited the Space Age I don't put a lot of faith in what the media gets wind of with regard to space technology. This stuff is really complicated, and the general public doesn't understand that test flights going awry is not necessarily a bad thing-- so officials often put a nice veneer on the results.
I hope it really was fantastic. A lot of people put a lot of time into this thing. But this thing is so politicized, I'm not holding my breath.
Well then, please allow me to be the first to say:
"Heck yeah!"
>> Standing on head makes smile of frown, but rest of face also upside down.
I am just glad I was not riding in that simulator. Did anyone else notice the separation, and the flight path of the (in the future to be occupied) simulator? The booster and the simulator appeared to tumble after separation. It could have been the camera angle I suppose, but that front section should have continued on, correct?
They only planned to recover the first stage from what I had read. As the NASA official stated it the second stage and mock crew capsule would splash into the ocean like a giant lawn dart and sink to the bottom. I thought the analogy was funny because thanks to the government some large percentage of the population (those under say 25) have no idea what a lawn dart IS.

I'd say something scathing and then list all the things the space program has benefited humanity and your daily life with but luckily NASA still has enough time to explain it all nicely without being condescending like I would have been:

Also... They have a particular section about helping humanity in general with feeding the world:

The upper stage was not a real upper stage. The capsule was a mass simulator. The first stage was only a 4-segment booster with a mass simulator filling in the location of the 5th segment. This flight was about aerodynamics, control authority and a test of the 1st stage recovery parachutes.

It pays to be obvious, especially if you have a reputation for being subtle.
according to wikipedia http://en.wikipedia.org/wiki/List_of_Constellation_missions the next mission is Ares 1-Y, in 2013, a full first stage, a real second stage, testing high altitude abort.
I was watching the launch with my kids on NASATV, and just when the stages separated, the leading stage started to tumble, and NASATV went black. When they came back in 20 seconds or so, they were following the larger stage on its descent.
I have to say, the supersonic vapor plume around the rocket during acceleration was awesome. I said to my kids, "look, they just broke the sound barrier," and the announcer came on with "passing Mach 1".
Very cool looking rocket, more narrow exhaust plume than I'm used to seeing, interesting angled ascent (it didn't go up straight vertically like a shuttle). We like to rag on NASA, but if this is really a an under-3-year project, who am I to cast stones?
My God, it's Full of Source!

oops. There are at least 3 test flights before that... a pad abort test in early 2010 and two ascent abort tests using a special booster, one in late 2010 (transonic) and one in late 2011 (max-Q).
"endless resources" to NASA. ahahahahahahahahaha. Oh wait, you were serious, let me laugh even harder. AHAHAHAHAHAHAHA.
Even with the very tiny amount of money the US spends on its space program (compared to something like military spending or social security) the human race as a whole has benefited significantly from the things we have learned while doing it. Not just that the moon is grey and barren, or that ants still make anthills in zero gravity, but new materials, new ways to do old things, new computing, new understanding about the universe, a better understanding of the sun and outer planets and greater understanding of the building blocks of the earth itself.
It wasn't just some wasted hole that they poured money into to piss off the Russians.
Space exploration and the whole area around how to actually explore space needs much more funding than it currently has.
Great. First we bomb the moon, looking for water. Then we bomb the Atlantic Ocean. Were we looking for Moons?
Some items to note:
(I largely copied this from a comment I made yesterday, but it still seems pertinent)
Yes, it was designed to do that. The NASA-TV footage talked about tumble motors. By causing them to tumble, they get slowed down more by the atmosphere. They won't travel as far downrange and they'll impact the water with less speed. This will make the parts easier to recover.

If not now, when? If not us, who?
deleting the extra space after periods so i can stay relevant, yeah.
I wish we would back a design like Skylon. Now that would be something to get really excited about and it would fill even the general population with a sense of awe to inspire a whole new generation of space exploration. http://en.wikipedia.org/wiki/Skylon [wikipedia.org]
Yeah sense of awe, as in WTF... the skylon is unrealistic for the following reasons:
1) Looking at the wikipedia article, first off, 50% faster than blackbird engines is a pure pipe dream. Material science has not improved enough for turbine blades to survive that, and the intakes required to decelerate incoming air to subsonic will either be too heavy, or impossible, or not distribute airflow evenly enough, etc etc. Tech and cad design help some, but not enough.
2) Second wiki article problem, twice the size (twice the wing area?) but three times the weight, that things going to be a real handful at take off.
3) The sabre engine probably will not work, as the designer himself only gives it a TRL of 2 or 3. By his own admission, that's right up there with warp drive proposals and telekinesis. The ISP is too low, the T/W is too low. Following the old 6-6-6 rule, whats wrong with 6% bigger fuel tanks and an off the shelf engine?
(The 6-6-6 rule is mach 6 (good f-ing luck) at 60Kfeet up (difficult to impossible for an air breathing engine) gets you a whopping 6% of the way to orbit)

It's been quite a while since the U.S. developed a new man-rated booster. In the last decades, we have learned a LOT about spacecraft. Unfortunately, what we learned is that something like the space shuttle is nowhere as maintenance free as we thought/hoped and is fantastically more expensive.
Since we can't build a Saturn V anymore (we'd have to substitute enough obsolete parts that it would be a new design anyway) and we know building a new shuttle is too expensive, it is good to see that manned spaceflight has a future in some form in the U.S.
Ares and Orion are take two on a reusable spacecraft now that we have a better idea what parts are practical to reuse and what parts aren't.
Unlike the Soyuz rocket, Ares includes reusable components. The use of solid fueled 1st stage is expected to make it safer and easier to prep for launch. Things get more interesting once the 2nd stage is ready. It may not sound like much but the engine re-start capability is a big deal.
It's not really a step backwards so much as a lateral step away from a dead-end branch that seemed like a good idea at the time. Manned space flight isn't actually out of the experimental stage yet (and certainly wasn't when the space shuttle was designed). Sometimes progress in experimental engineering looks like a step back at first glance.
$17B a year is not going to make a dent in the economy or in poverty or homelessness, or climate change or anything else. Those are the results of human nature and/or normal cycles, and fixing them is a matter of political will and good policy, not a few extra dollars.
Spending a small amount on space exploration is EXACTLY what the government exists to do -- do things that require large amounts of money (for an individual or group) with high risks and low immediate reward, but that have the potential for great reward for all of society.
And if you think $17B a year with increases less than inflation and ever new directives and goals are 'endless resources' I think you need to take a look at the scale of the federal budget.
