Discovery launched

11:48 a.m. - Right on time, we have main engine cutoff and external tank separation as Discovery reaches space.

11:40 a.m. - The solid rocket boosters have separated. Discovery climbs toward space, and all is going well with the flight as the shuttle's three main engines power the vehicle through Earth's atmosphere.

11:38 a.m. - Three... two... one... and liftoff of space shuttle Discovery carrying the seven STS-120 astronauts! The shuttle has cleared the launch tower, beginning its mission to bring Harmony to the International Space Station.

The shuttle rolls into a head-down position as it climbs skyward. Discovery's three main engines throttle down to about 72 percent around 30 seconds after liftoff. One minute after launch, the engines throttle up again to 104 percent, bringing the vehicle to the peak of aerodynamic pressure called "max Q."

Two minutes into flight, the twin solid rocket boosters will burn out and separate, falling back to Earth toward the Atlantic Ocean, where the booster recovery ships, Freedom Star and Liberty Star, are stationed to retrieve them.

11:33 a.m. - All systems remain "go" with the launch of Discovery on mission STS-120 just minutes away.

11:48 a.m. - Right on time, we have main engine cutoff and external tank separation as Discovery reaches space.

11:40 a.m. - The solid rocket boosters have separated. Discovery climbs toward space, and all is going well with the flight as the shuttle's three main engines power the vehicle through Earth's atmosphere.

11:38 a.m. - Three... two... one... and liftoff of space shuttle Discovery carrying the seven STS-120 astronauts! The shuttle has cleared the launch tower, beginning its mission to bring Harmony to the International Space Station.

The shuttle rolls into a head-down position as it climbs skyward. Discovery's three main engines throttle down to about 72 percent around 30 seconds after liftoff. One minute after launch, the engines throttle up again to 104 percent, bringing the vehicle to the peak of aerodynamic pressure called "max Q."

Two minutes into flight, the twin solid rocket boosters will burn out and separate, falling back to Earth toward the Atlantic Ocean, where the booster recovery ships, Freedom Star and Liberty Star, are stationed to retrieve them.

11:33 a.m. - All systems remain "go" with the launch of Discovery on mission STS-120 just minutes away.
