KENNEDY SPACE CENTER, Fla. -- The first space-bound Orion capsule, the centerpiece of NASA's post-shuttle push to break out of low Earth orbit for eventual manned flights to a variety of deep space targets, was officially unveiled at NASA's Florida spaceport today. The spacecraft will be outfitted for an unmanned test flight in 2014.

"As KSC celebrates its 50th anniversary this month, I can't think of a more appropriate way to celebrate than by having the very first Orion Multi-Purpose Crew Vehicle here at KSC," Robert Cabana, the center's director and a former shuttle … Read more

A United Launch Alliance Delta 4 rocket, the most powerful in the postshuttle U.S. inventory, boosted a top-secret National Reconnaissance Office spy satellite into space early Friday, after a spectacular morning launch from Cape Canaveral.

Running three hours late because of technical snags, the 232-foot-tall rocket, made up of three liquid-fueled common core boosters and a powerful upper stage, roared to life at 9:15 a.m. EDT (GMT-4) and quickly climbed away from launch complex 37 at the Cape Canaveral Air Force Station.

Generating nearly two-and-a-half million pounds of thrust from three upgraded Pratt and Whitney Rocketdyne RS-68A … Read more

A United Launch Alliance Atlas 5 rocket carrying a classified National Reconnaissance Office satellite blasted off today, creating a dramatic sky show as it boosted its secret payload into orbit.

Running two days late because of work to fix an environmental control system duct, the 188-foot-tall Atlas 5 roared to life at 8:28 a.m. EDT and climbed away from launch complex 41 at the Cape Canaveral Air Force Station, trailing a brilliant plume of flame from its Russian-designed RD-180 first-stage engine.

Without any strap-on solid-fuel boosters, the initial climb out appeared relatively sedate compared with more powerful variants … Read more

KENNEDY SPACE CENTER, Fla.--A towering Atlas 5 rocket flashed to life and vaulted into space Saturday, putting on a spectacular weekend sky show as it boosted NASA's $2.5 billion Mars Science Laboratory rover on an eight-and-a-half-month, 352-million-mile voyage to the Red Planet.

Equipped with a nuclear power pack, a robot arm, and a suite of sophisticated instruments, the mobile laboratory, dubbed Curiosity in a student naming contest, is expected to spend at least two years looking for organic compounds and signs of past or present habitability in the layered terrain at the heart of a 100-mile-wide crater.… Read more

KENNEDY SPACE CENTER, Fla.--NASA's $2.4 billion Mars Science Laboratory has completed an exhaustive series of functional tests to verify the car-size rover's readiness for launch in November on an eight-and-a-half-month voyage to the Red Planet and a dramatic rocket-powered "sky crane" descent to the surface, officials said today.

Engineers now plan to carefully fold up the rover's robot arm, camera mast, wheels, and suspension so it can be packed inside a protective aeroshell that, in turn, will be attached to the bottom of a rocket-powered descent stage. The entire spacecraft then will be … Read more

KENNEDY SPACE CENTER, Fla.--A powerful United Launch Alliance Atlas 5 rocket roared to life today and launched NASA's solar-powered Juno space probe on a five-year voyage to Jupiter, the first step in a $1.1 billion mission to look for clues about the origins of the solar system in the hidden heart of its largest planet.

"What we're really going after are some of the most fundamental questions of our solar system--how Jupiter formed, how it evolved, what really happened early in the solar system that eventually led to all of us and the terrestrial planets," said Scott Bolton, the principal investigator. "These are really basic questions: who are we, where did we come from, how did we get here?

"We're kind of going after this recipe of how planets are made. We're getting the ingredients of Jupiter, we're going to understand what the structure is like inside, how was it built, and that will give us guidance as to what happened in that early time that eventually led to us."

The towering 197-foot-tall Atlas 5, equipped with five solid-fuel strap-on boosters for extra power, ignited with a ground-shaking roar at 12:25 p.m. EDT, generating 2.5 million pounds of thrust and instantly pushing the spacecraft away from launch complex 41 at the Cape Canaveral Air Force Station. It was only the second launch of a five strap-on Atlas 5, the most powerful version offered by United Launch Alliance.

Liftoff was delayed 51 minutes to resolve two technical issues and to make sure a boat that strayed into the launch danger zone cleared the area.

Climbing away atop a brilliant plume of fiery exhaust, the rocket accelerated through the sound barrier 34 seconds after liftoff, arcing away to the east and putting on a spectacular lunchtime show for tourists and area residents. The strap-on boosters burned out and peeled off about a minute later and the first stage shut down and fell away as planned four and a half minutes after launch.

The rocket's hydrogen-fueled Centaur upper stage then carried out a six-minute burn to boost the spacecraft into a temporary parking orbit. A second nine-minute Centaur firing 31 minutes later accelerated Juno to 25,000 mph, or 7 miles per second--interplanetary escape velocity--and three minutes later, the 4-ton spacecraft separated from the Centaur to fly on its own.… Read more

Boeing will use United Launch Alliance Atlas 5 rockets for initial test flights of the company's proposed CST-100 manned spacecraft, a seven-seat capsule being developed for commercial missions to and from government and private-sector space stations in low-Earth orbit, company officials announced today.

John Elbon, vice president and program manager of Boeing commercial crew transportation systems, said four test flights of the CST-100 spacecraft are envisioned, assuming continued NASA funding, including an on-the-launch-pad abort test in 2014 that will not require a booster.

The other three flights will use a version of the Atlas 5 that includes one solid-fuel … Read more
