CAPE CANAVERAL, Fla. ? The six astronauts who will fly on spaceshuttle Discovery during its historic final flight have arrived at theirFlorida launch site for the planned Monday launch, after a slight delay due toan aircraft glitch. ?

Discovery commander Steve Lindsey and four of his crewmates beganlanding their NASA T-38 jets here at the Kennedy Space Center at about 3 p.m.EDT (1900 GMT). A plane swap for the sixth crewmember, mission specialist AlvinDrew, delayed his arrival by an hour.

"It?s great to be down here ? what an excitingweek," Lindsey told reporters who had gathered for the crew's arrival."Hopefully, weather permitting, all goes well and we'll have a nice Nov.1 on-time launch. We're looking forward to it."

On its 11-day mission, Discovery will haul critical spareparts to the space station, including a storage room and a humanoidrobot to assist the crew of the orbiting laboratory. It will be the 39thand last space voyage for Discovery before NASA retires is shuttle fleet nextyear.

Lindsey, pilot Eric Boe, and mission specialists MichaelBarratt, Nicole Stott and Tim Kopra flew in on three of NASA's supersonic T-38 trainingjets from their the Johnson Space Center in Houston.

Drew's arrival was delayed about an hour, after issues withhis T-38 aircraft forced him to return to Houston to switch planes. He toucheddown at the Florida spaceport at approximately 4 p.m. EDT (2000 GMT).

A grateful crew

Lindsey also expressed gratitude to the teams at KennedySpace Center who, just last weekend, completed a speedy repair on two leakyseals that were found on Discovery's fuel line.

"They did a fantastic job getting the vehicle ready forus," Lindsey said.

The STS-133 crew is scheduled to launch Monday at 4:40 p.m.EDT (2040 GMT) to the International Space Station.

Launch day looms

In the remaining days before launch, the astronauts willremain in medical quarantine ? a standard precaution ? to prevent illnessbefore the mission. They will also spend the next several days reviewingmission details and completing last-minute training exercises.

The official countdown for Discovery's launch will begin tomorrow (Oct. 29) at3 p.m. EDT (1900 GMT).

Discovery'sfinal flight will be NASA's 133rd shuttle mission, before the space agencybrings its 30-year space shuttle program to a close in 2011.

NASA is retiring the three remaining shuttles in its fleet ?Discovery, Atlantis and Endeavour ?to make way for a new plan aimed at sendingastronauts to visit an asteroid and Mars. Discovery is the oldest of NASA'sspace shuttles.

President Obama recently signed a major NASA act that turnshis vision for U.S. space exploration into law. The NASAauthorization act scraps the space agency's previous moon-oriented goal andpaves the way for a manned mission to an asteroid by 2025. A manned mission toMars is envisioned for some time in the 2030s.

The bill also calls for a budget of $19 billion for NASA in2011, adding one extra space shuttle flight before the fleet retires for good,and the extension of the International Space Station through at least 2020.
