KENNEDY SPACE CENTER, Fla.--NASA's towering Ares I-X rocket was hauled to the launch pad early Tuesday for blastoff October 27 on a $445 million unmanned test flight that likely will play a major role in the ongoing debate about NASA's post-shuttle manned space program.

The slow trip to pad 39B began at 1:39 a.m. EDT Tuesday when a powerful crawler-transporter carrying the Ares I-X rocket and its mobile launch platform slowly pulled out of the Vehicle Assembly Building at the Kennedy Space Center. Powerful spotlights illuminated the vehicle as it emerged from the VAB, providing … Read more

A Russian Soyuz spacecraft carrying commander Gennady Padalka, flight engineer Michael Barratt, and Cirque du Soleil founder Guy Laliberté undocked from the International Space Station on Saturday and plunged to a successful landing in Kazakhstan early Sunday.

Descending under a big orange-and-white parachute, the Soyuz TMA-14's descent module settled to a jarring rocket-assisted touchdown at 12:32 a.m. EDT (10:32 a.m. local time) Sunday to close out a 50-minute descent from orbit. Russian recovery forces, including U.S. and Russian flight surgeons, monitored the final stages of the descent before moving in to provide assistance, … Read more

In a brute-force search for ice on the moon, an empty 5,000-pound rocket stage traveling twice as fast as a rifle bullet crashed into a permanently shadowed crater near the moon's south pole Friday, presumably blasting out tons of debris for examination by an instrumented probe that carried out its own kamikaze plunge four minutes later.

While the initial impact at 4:31 a.m. PDT did not prove especially dramatic--it was not even visible in real-time video from the Lunar Crater Observation and Sensing Satellite (LCROSS)--scientists said a camera sensitive to temperature variations clearly recorded the … Read more

The Soyuz TMA-16 spacecraft carrying cosmonaut Maxim Suraev, NASA flight engineer Jeffrey Williams, and Cirque du Soleil founder Guy Laliberté maneuvered to a smooth docking with the International Space Station early Friday to close out a two-day orbital chase.

With Suraev and Williams closely monitoring the final stages of the automated rendezvous, the small capsule's docking mechanism engaged its counterpart at the aft port of the Zvezda command module at 4:35 a.m. EDT as the two spacecraft sailed high above northeast Kazakhstan. Hooks and latches then engaged to pull the Soyuz firmly into place.

A Russian Soyuz rocket blasted off from Yuri Gagarin's launch pad in Kazakhstan Wednesday, carrying two fresh crew members and the founder of Cirque du Soleil on a voyage to the International Space Station.

Under a cloudless blue sky, the Soyuz TMA-16 rumbled to life and soared away from the Baikonur Cosmodrome in Kazakhstan at 3:14:42 a.m. EDT, roughly the moment Earth's rotation carried the launch pad into the plane of the station's orbit.

Soyuz commander Maxim Suraev, making his first flight, monitored the ascent from the cramped capsule's center seat, assisted by … Read more

A United Launch Alliance Delta 2 rocket roared to life and thundered away from the Cape Canaveral Air Force Station Friday, successfully boosting a pair of experimental missile-tracking satellites into orbit for the U.S. Missile Defense Agency.

With its roots in the old "Star Wars" program, the goal of the $1.5 billion Space Tracking and Surveillance System mission is to demonstrate the ability to detect and track enemy missiles from launch, through the so-called mid-course phase of flight to atmospheric entry, providing more accurate targeting data for interceptors.

"The purpose of these satellites is to … Read more

Data from a comet-bound NASA probe, a robotic mission to Saturn, and a U.S. instrument aboard an Indian spacecraft have provided clear evidence that at least trace amounts of water exist on the moon's surface, researchers said Thursday.

While scientists have long suspected that water ice from comet impacts is trapped in cold, permanently shadowed craters near the moon's poles, the new data indicates that water molecules form and dissipate across broader areas, even in lunar daylight.

While the data represent a major surprise and a "really profound discovery," one scientist said, researchers cautioned that … Read more

KENNEDY SPACE CENTER, Fla.--Chief astronaut Steven Lindsey, a veteran of four shuttle missions, will command an all-veteran six-member crew for the final planned space shuttle flight next year, NASA announced Friday. Peggy Whitson, an experienced space station commander, will take over as chief astronaut as the shuttle program winds down.

Lindsey will be joined by pilot Eric Boe and mission specialists Benjamin "Al" Drew, Michael Barratt, Nicole Stott, and Timothy Kopra, all space veterans. Barratt and Stott are currently in orbit aboard the International Space Station while Kopra just returned from a long-duration stay.

Launch aboard the … Read more

After two months of checkout and calibration, NASA's $504 million Lunar Reconnaissance Orbiter was maneuvered into a circular 31-mile-high mapping orbit Tuesday, and scientists said Thursday the spacecraft's instruments are delivering intriguing clues about the possible presence of water ice.

"The moon is starting to reveal her secrets, but some of those secrets are tantalizingly complex," said Michael Wargo, NASA's chief lunar scientist.

Scientists expected the spacecraft to find signs of hydrogen--an indicator of possible water ice deposits--in permanently shadowed craters near the moon's south pole. Ice could be expected from cometary impacts over … Read more
