After the Final Space Shuttle Flight in 2010-11.America will be bringing a new Space Vehicle on-line. The Orion/Ares Project will be our new access to Low earth Orbit.
And eventually back to Lunar Orbit and the Lunar Surface.

Those over 45 may remember the Look of the Orion Spacecraft is very Similar to that of the Apollo Spacecraft.

A Good design that brought every American Home safely from Earth orbit and the Moon.

ARES I

Operational Ares I Shown on New Mobile Launcher (NASA)

Ares I, a classic example of a government-funded and managed launch vehicle program, is expected to become the third human space launcher developed entirely by the U.S. National Aeronautics and Space Administration (NASA).[1] Ares I is being developed to do just one job - launch the Orion Crew Exploration Vehicle. Orion is planned to carry on NASA's human spaceflight efforts after Space Shuttle is retired in 2010.

As currently envisioned, the Ares I Crew Launch Vehicle will consist of a five-segment solid propellant first stage derived from Space Shuttle's four-segment reusable solid rocket booster (RSRB) topped by an all-new liquid hydrogen/oxygen upper stage. The upper stage will be powered by a new J-2X upper stage engine derived, in part, from the J-2 engine used on Apollo/Saturn upper stages and the simplified J-2S engine developed but never flown.

Mission requirements call for the two-stage launch vehicle to be capable of inserting a 23.63 tonne Orion spacecraft into a -55.56 x 185.2 km x 28.5 deg suborbital trajectory. This will aim the spent Ares I second stage toward an Indian Ocean impact while Orion fires its service module engine to complete the ascent to orbit. A service module burn at first apogee would need to provide 73.2 meters per second of additional velocity to circularize the orbit at 185.2 km, which is roughly the same as the "OMS-2" burn used to complete the space shuttle ascent to orbit.

Ares I Description

The Ares I/Orion stack is expected to weigh about 906 tonnes at liftoff and stand more than 94 meters to the tip of the launch abort system mast. The launch vehicle itself will be about 79.4 meters from its base to the top of its Instrument Unit. The first stage will be 3.71 meters in diameter, the upper stage 5.5 meters in diameter, and the Orion spacecraft will be 5 meters in diameter.

The first stage will produce roughly 1,600 tonnes of thrust at liftoff and will average 1,245 tonnes of thrust during its roughly 130 second burn. Approximately 630 tonnes of polybutadiene acrylonitride (PBAN) solid propellant will be consumed during the burn. The movable RSRB nozzle will provide pitch and yaw control while a new monopropellant roll control system located in the interstage will control vehicle roll during the first stage burn.

First stage separation will occur at roughly 59 km at a velocity of about 2,024 meters per second. Booster separation motors will back the stage away from the upper stage and interstage, tumble motors will cause it to enter a slow spin, and the tapered frustum section at the top of the stage will separate. The stage will reach a 99 km apogee before beginning its descent. A drogue chute will begin to deploy when the RSRB passes 4.6 km, having already been slowed by the atmosphere to a speed of about 195 meters per second. The stage will impact the Atlantic Ocean under a triple ringsail main chute canopy about 7 minutes 45 seconds after liftoff.

A cylindrical interstage will connect the RSRB and upper stages. It will be composed of composite materials, marking the first large-scale use of a composite structural element in a U.S. human-rated launch vehicle. The interstage will contain important propulsion elements, including the first stage roll control system, the booster separation motors (the 8.39 tonne thrust motors currently located in the RSRB nose), and two interstage separation systems. Current plans call for the roll control system to use monopropellant hydrazine thrusters. Thrust will be produced by the decomposition of hydrazine as it passes through a catalyst bed.

The upper stage J-2X engine will burn liquid hydrogen and liquid oxygen for about 463 seconds, producing 133 tonnes of thrust at a 448 second vacuum specific impulse. A 125 tonne thrust J-2XD version may be used for initial flights. Velocity at shutdown will be somewhere in the range of 7,800 meters per second.

The J-2X engine will swivel to provide pitch and yaw control. Roll control will be provided by a blow-down system feeding monopropellant hydrazine to a series of attitude control thrusters. Small solid motors will fire to separate the upper stage from the interstage and to settle propellants.

An aft liquid oxygen tank will be topped by a forward liquid hydrogen tank, with a common bulkhead between, to compose the upper stage structure. The tanks will hold up to 128 tonnes of propellants. Tanks will be fabricated from the same 2195 aluminum-lithium alloy currently used to build shuttle External Tanks. The stage itself will be assembled at the current Michoud External Tank factory in New Orleans.

A cylindrical Instrument Unit will top the upper stage. It will contain guidance and control systems for the entire launch vehicle. Link

Judge: Corps of Engineers can be sued over Katrina flooding The Army Corps of Engineers can be held liable for flood damage caused by a "hurricane highway," a navigation channel that is believed to have funneled Hurricane Katrina's storm surge into the city, a federal judge ruled Friday. The Corps of Engineers had argued that it was immune from liability because the channel is part of New Orleans' flood control system. The law says the federal government cannot be sued if something goes wrong with a flood control project such as a levee, reservoir or dam. Judge Stanwood Duval dismissed that argument, saying the Mississippi River-Gulf Outlet, or MRGO, was clearly a ship channel and not a flood control project.

Good Morning. Hope you have a wonderful day.

Not bad 2.5 years after calamity. Lotsa folks came and had a Great time here.And I thank every one of them Personally here. We spent a good 300 bucks over 2 weekends there. And we were thrilled every day. Thanx for coming to NOLA for Jazz Fest. Jazzfest attracts up to 400,000, highest since Katrina struck Posted by Leslie Williams, the Times-Picayune May 06, 2008 8:54AM This year's Jazzfest ended with its highest attendance since Hurricane Katrina. "We estimate 375,000 to 400,000 people came to the festival," said Louis Edwards, an associate producer of the event, which is officially called the New Orleans Jazz and Heritage Festival presented by Shell. That's despite rain at the Fair Grounds on Friday and Saturday during the first week and on Saturday morning during the second week, he said. Edwards attributed the rising head count to "the momentum of the comeback of the festival and the comeback of this city." The first post-Katrina Jazzfest, in 2006, attracted at least 50,000 fewer people: 300,000 to 350,000 compared with 400,000 in 2005, according to an official estimate. "In 2007, we had about 375,000 people," Edwards said. The upward trend, however, still lags far behind the 39-year-old festival's record high of 618,000 visitors in 2001. In 2005, Jazzfest was seven days long: three days in April and four days in May. The 2008 and 2001 festivals also went on for seven days. In 2006 and 2007, the festival was a day shorter, three days both weeks.

EmmyRose 11:34 AM CDT on May 09, 2008 May 8, 2008, 5:52PM Astronaut trades jokes with Colbert in space interview By MARK CARREAU Copyright 2008 Houston Chronicle NASA astronaut Garrett Reisman, who is currently orbiting the Earth aboad the international space station, matched wits today with Stephen Colbert, who pokes fun nightly at world events from the anchor desk of The Colbert Report. The exchange airs on Comedy Central at 10:30 p.m. CDT. The two men soft-sparred for 20 minutes over NASA-TV earlier today, with Reisman drawing as much studio applause as his better known host during a taping of the appearance. "You are an astronaut, you are a scientist. you are an engineer, but more importantly you are a member of the Colbert nation, correct?," the mock anchor puffed. "Actually, I would say the Colbert universe, that would be more appropriate," said Reisman, 40, who holds a doctorate in mechanical engineering from the California Institute of Technology. "We have gone galactic," crowed Colbert. "I should say something really profound. Eat it, Jon Stewart! I'm talking to space." Perhaps wisely, Reisman gave no hint of whether he's been booked for a future appearance on Jon Stewart's The Daily Show which airs ahead of the Colbert Nation on Comedy Central. "What is you job on the space station," Colbert probed. "I'm the flight engineer No. 2, which basically means I do whatever they need me to do. We spend a lot of time keeping it running, keeping it ship-shape and doing some scientific experiments and a bunch of otther stuff," Reisman explained. "Are you saying you are janitor with a Phd," asked Colbert. "I'm a bit of a glorified janitor. That is probably a pretty good decription. I do a lot of cleaning," Reisman acknowledged. The two men discussed the challenges of using the space station's waterless toilet, fitting in socially with two Russian crewmates, and living for weeks without a refrigerator to chill ice cream and beer. Reisman, who is scheduled to return to Earth in mid-June after two weeks on the space station, explained his preparations for the flight included a two-week stay in an undersea habitat off of Florida's Atlantic Coast in 2003. "What do you have against the rest of humanity that you have to flee from us every so often," asked Colbert. "I think it's more what the rest of humanity has against me. I keep being sent off to these far places. I try not to take it personally," Colbert's space guest responded. "OK, we have a great job for Reisman," Colbert chortled in his best bureaucratic personna. "Send him to the bottom of the ocean. That's not far enough. Launch him into space."
