Interesting NASA test of the Ares rocket... 3.6million pounds of thrust. Must have been a mother securing that thing to the ground.

Power

My bro at Honeywell has been developing software for the Orion capsule that could someday be launched by Ares for moon missions. Hmmm

:thumbsup:

I hope that they can get the appropriate funding to continue the Ares/Orion programs... Time to kick space exploration up a notch!

I don't know... I'm sure the Saturn V has at least twice the thrust but look at the size of it. You need that much thrust just to lift all the propellant. I'm sure if someone did the math on the thrust/weight ratios the Ares would be much more efficient.

I believe the Ares is basically a bigger, improved version of the shuttle boosters.

I believe that the number for the Ares is before the crew capsule, etc while the shuttle number is after the shuttle itself. For example, say the Orion capsule weighted 45,000 (not sure what it is supposed to weight) then they system payload capacity would only be 10,000lbs. While the shuttle has a system payload capacity of 53,600lbs

Wow. The flame exited at mach 3 and was nearly 4500F.

Bad day to be a small animal nearby in the ground taking a nap :)

I think most rockets nowadays use liquid H2/O2 to generate thrust. All that's produced is water vapor, which really doesn't contribute that much to the CO2 load in the atmosphere.

Must have been a mother securing that thing to the ground.

The thrust block in front of the rocket is about 20 feet tall, 20 feet deep, 20 feet wide, and goes into the ground about 20 feet. It is solid steel reinforced concrete and took about three weeks of continual concrete pouring to build. At the time it was the second largest concrete pour ever in the state of Utah.

It has a conical thrust adapter which attatches to the rocket that that is made out of about 8" steel rods (I never counted them so I don't know how many there are). It adapts the 12 foot diameter rocket down to about 4 feet at the thrust block.

At the rear of the rocket is the rear test stand. It is the structure you see standing upright near the nozzle on the left side of the rocket. Most of it is below the level of the floor.

There is a large wire rope that is attatched at the rear test stand and runs forward about 3/4 of the rocket and is attatched to the floor on either side. It is to restrain the rocket in case something breaks.

About 1/3 of the way down the rocket from the front is a structure that goes around the rocket. It is not attatched to the rocket. It's purpose is to break open the case of the rocket if it gets loose. When the case is broken, the propellant burns out in seconds without launching it somewhere.

Shuttle boosters are built of 4 segments. Ares is the same design but with 5 segments. With the imfamous (redesigned) Challenger O-Rings between them.

When I worked there, we couldn't measure the plume. Any instrument that came in contact with it was destroyed before it could report. Optical measurements didn't work either. Maybe they can do it now, I don't know.

The rocket is shooting up a small canyon. There was a dead roasted deer up there after a burn. We did a sweep to make sure it was clear, but it wandered down after the countdown began.

I haven't been there in about 12 years so I don't know about the systems they are using or much about the Ares.

If only they could figure out how to do inflight refueling!! ;)

So what happened to the concept of launching from high altitude off of a 747 like a cruise missle? Seems kind of stupid to start from a dead stop if you dont have to. A rocket probably wastes quite a bit in the first mile above the earth. Just getting up to the speed of a jet probably takes quite a bit of thrust.

The hard part is not getting to Mars, the hard part would be taking off from mars. Mars has a thinner atmosphere so there may be less air pressure. This also means less lift.

Just tie on a few high altitude weather balloons.

Remember the contest to get the first commercial vehicle into space?

Maybe less lift for a wing but the thinner atmosphere and less gravitational pull means easier rocket launches.

Sweet, my uncle is a petroleum engineer working on the Ares I. He told me they were planning this test when I was staying with him during my internship with Army R&D at Red Stone Arsenal (NASA's Marshall Space Center is located inside that military base). Glad it worked!

The reaction generates water which is more or less one of the most powerful greenhouse gases.

I remember hearing that Mars is something like 1/3 the gravity of Earth, but with 1/10th as much lift.

Yes but it dissipates from the atmosphere in micro-time (a few days) compared any other gas.

agreed. if the government is going to spend money on make-work socialist type jobs, they might as well be interesting jobs.

plus, with the moon program there was some flow-down of technology to the private sector. i.e. government sponsored IRAD ended up benefiting (sort of) the general public.

No way! We need to stop the ocean from evaporating ASAP!
