NASA fuels space shuttle Atlantis for afternoon liftoff, weather takes slight turn for worse

NASA fuels space shuttle Atlantis for liftoff

CAPE CANAVERAL, Fla. — NASA fueled space shuttle Atlantis on Monday for an afternoon liftoff to the space station, despite increasingly cloudy skies.

Forecasters put the odds of acceptable weather at 70 percent, not nearly as good as previous days. Low clouds were the main concern for the 2:28 p.m. liftoff.

The six astronauts grinned and waved as they headed to the launch pad late Monday morning. Commander Charles Hobaugh was the first one into the shuttle.

Atlantis is loaded with big spare parts for the International Space Station. NASA wants to stockpile as much equipment there as possible before the shuttle fleet is retired next year.

The 11-day flight will keep the astronauts in orbit through Thanksgiving. They will unload nearly 30,000 pounds of pumps, tanks and other spare parts, as well as science experiments. Three spacewalks will be conducted to carry out the work.

It is NASA’s last shuttle flight of the year and among only six remaining.

Gathering for the launch were about 100 Twittering space fans who won invitations from NASA. They were among the first to sign up online last month for this first-ever launch “tweetup.”

NASA put up a white circus-like tent at the press site of Kennedy Space Center, expressly for the Twitter crowd. The long rows of tables covered with laptops were briefly vacated as the crowd walked over to the main road to the launch pad to watch the crew drive by in the so-called astrovan. The crowd cheered and waved to the astronauts, and immediately posted Twitter updates.

“100 nerds against the road waving at the astrovan,” one wrote.

“I was begging the astronauts to take me with them as they stopped and waved at us,” another tweeted.

NASA estimates the 100 tweeters have a following of more than 150,000. The space agency sees it as a beneficial outreach program.
