Engineers made final preparations Tuesday morning for the long-awaited launch of NASA's towering Ares I-X rocket - the 33-story centerpiece of a $445 million test flight expected to generate valuable engineering data for development of a post-shuttle replacement.

The planned launch comes on the heels of a report by a presidential panel of space experts that concluded NASA's current plans to build new Ares rockets and establish bases on the moon by the early 2020s is not feasible without an additional $3 billion to $6 billion a year.

The slender Ares I-X, its second stage wider than the first, stands twice as tall as a space shuttle "stack." But its pencil-thin appearance quickly led to a somewhat derisive nickname: the "stick."

A seven-hour countdown began at 1 a.m. Eastern on Tuesday, targeting the opening of a four-hour launch window at 8 a.m.

Forecasters, however, were predicting a 60 percent chance of clouds and rain that could prevent good visibility, needed for precise optical tracking, and cause static charges to build up around the rocket, interfering with communications, including the self-destruct system if needed.

For the first test flight - Ares I-X - NASA is using a standard four-segment shuttle booster with an empty fifth segment, housing guidance and navigation equipment adapted from Lockheed Martin's Atlas 5 rocket, and new 150-foot-diameter parachutes to lower the spent rocket to the ocean for recovery.

A dummy second stage loaded with ballast and topped off with a make-believe Orion capsule and abort rocket are bolted to the top of the first stage.

More than 700 sensors are mounted on the Ares I-X to record an enormous amount of engineering data on all phases of flight, from launch through motor burn out two minutes later, through stage separation, parachute deployment and ocean impact. Multiple video cameras are mounted on the rocket to provide real-time views of critical elements.

Engineers say the short flight will help them resolve questions about first stage vibration, roll control, aerodynamic forces and thermal effects, as well as stage separation systems and recovery of the first stage using new 150-foot-wide parachutes.

"One test is worth a thousand expert opinions," said Jon Cowart, Ares I-X deputy mission manager at the Kennedy Space Center. "It's brand new, it's a long, thin rocket. We want to make sure we can guide this thing. Balance a broomstick on the end of your finger, you'll get some idea of what we're dealing with here."

Said former NASA Administrator Mike Griffin, the man who approved the Ares architecture: "This is a vehicle that, when you look at it, is long and slender. That has caused, quite rightly, of course, at the top level, a lot of concern that it will be difficult to control."

"People think of launch vehicles as solid objects and they aren't, really," he said in an interview. "What you're really doing is pushing a pasta noodle up a hill. So you're pushing a pasta noodle up hill and you have to do it carefully... The issue is the reaction of the vehicle in a stability and control sense."

While engineers are confident the slender rocket will, in fact, clear the launch pad service gantry and follow its programmed trajectory, "we're not going to guarantee this is going to work," said Bob Ess, the mission manager.

"This is a flight test and for the first time, we're testing many systems in the same vehicle simultaneously," he said. "We have very high confidence it's going to work, but there are some areas we're testing for the first time. That's why we're doing the test."

Added Launch Director Ed Mango: "We wouldn't go if we didn't think the vehicle is going to fly right."

If the weather prevents a launch Tuesday, engineers will recycle for another attempt at 8 a.m. Wednesday, when forecaster expect a 60 percent chance of acceptable weather. NASA does not yet have a third launch date booked with the Air Force Eastern Range, which provides telemetry and tracking support for all rockets launched from Florida. Assuming Thursday is available, forecasters are predicting a 70 percent chance of good weather.

Space Politics:

While the current Ares I program was among five options presented to the White House by the expert panel, several members made it clear they believe it would make more sense to scrap the rocket in favor of commercially developed boosters and capsules that could carry U.S. astronauts to and from the International Space Station.

NASA then could concentrate on developing a heavy-lift rocket in support of a so-called "flexible path" architecture that would forego near-term moon landings in favor of manned missions to orbit or fly by the moon or even Mars with possible landings on Martian moons or asteroids. The long-term goal - landings on Mars - would be developed in parallel in a more incremental fashion.

That approach, too, would require additional funding and while many observers believe the Ares I will be abandoned, the Obama administration has not yet announced what changes might be ordered.

"My crystal ball is that Obama will, at least for fiscal 2011, add a billion or so to the NASA budget - the key will be the out-year budget - and endorse something like the flexible path," said John Logsdon, a space policy analyst at George Washington University and a member of the Columbia Accident Investigation Board.

"There's no doubt that we're going to extend station (beyond 2015) and I think there is little doubt that we're going to depend on what people are calling commercial providers to be the transport system for crew to station as soon as they're ready," he said.

But Leroy Chiao, a former astronaut and member of the U.S. Human Spaceflight Plans Committee chartered by the Obama administration, said in an interview that "it's important to emphasize that we were presenting options, not recommendations."

"Despite what's been going on in the blogosphere, the panel didn't come up and saying (NASA) should cancel Ares I, which a lot of people think we actually did," Chiao said. "As far as the flight test ... there are definitely things to be learned. And I think no matter what, it's certainly worthwhile going forward with the test because frankly, it would probably have cost just as much money to stand down."

In the end, he said, "it's really up to the decision makers as to which path to go down. So Ares I is not dead by a long shot."

Are prioities seem to be $173 billion the U.S. government has poured into AIG...whatever that is. At least we can see what NASA does with money.

I'm eagerly looking forward to the results of this. The article even mentioned a "self-destruct" system. I have visions of this big red button that, when pressed, triggers a charming female voice saying something like "Self-destruct system engaging in 20 seconds. Thank you and enjoy your flight."

Joking aside, this should be an interesting test. And tests are never a waste of money.

Another multi-million dollar waste of money.

This ONE ROCKET would have bought cadillac health insurance for almost 30,000 families, for one year.

Where are our priorities?

[hungry1968-16]

If medicare fraud is such a problem, then why didn't the conservatives do something about it when they had complete control in Washington for 6 years?

Why does it takes complete control by the democrats before something is done about it?

Do you know anyone on kidney dialysis? Do you know a diebetic with an insulin pump? Space technology benefits humanity a thousand fold.

I love it when morons use technology developed from the space program to complain that the space program is a waste of money. Idiots.

NASA Preps for Ares I-X Rocket Launch



WASTE OF MONEY.

[pensacola8-2009]

I am confident that the Ares 1-X will live up to the expectations of engineers. The concept of future planetary missions that divides crew from supplies and launches them independently and docks them together for a long trip is very innovative.

I will concede that the country's interest in an economic recovery, a new health care system, and an escalating war while a space program is in the back seat, nearly sounds like the mid 1960's repeating itself. I will also remind readers of NASA's finest hours just a few short years after the drama paused just long enough to see how much the world was about to change when astronauts landed on the moon.

The engineers and astronauts of NASA have exhibited focus and been faithful to their missions without lapse. I applaud their achievements in the developments of technology and anxiously await to see the results of their new project.

I also urge President Obama to keep the space program alive and funded to achieve their agenda. I feel it is absolutely essential to remain competitive and capitalize on the spin-off industries developed from the technology.

You can't catch a fish unless you have a hook in the water, so we need to keep a space program alive and continue our participation in high tech industry development.
