One giant leap for NASA as space shuttle projects finish

The shuttle Atlantis astronauts finished packing more than two tonnes of old equipment and trash from the International Space Station into a cargo hauler yesterday for the last shuttle ride back to Earth.

The Italian-built storage pod will be loaded into Atlantis's payload bay early today in advance of the shuttle's departure from the station early tomorrow.

The 13-day mission, the last for NASA's 30-year-old space shuttle programme, is due to end with a landing at the Kennedy Space Centre in Florida at 9.57am GMT on Thursday.

"This is really the last train out of town," Atlantis commander Chris Ferguson said during an in-flight interview. "I don't think the full magnitude of everything is really going to hit us until after the wheels stop."

Mr Ferguson and his three crewmates delivered more than five tonnes of food, clothing, equipment and other supplies for the outpost, a $100bn (€70.6bn) project of 16 countries that was finished earlier this year after more than a decade of construction 350km above Earth.

The supplies aboard Atlantis are intended to tide over the station until NASA's newly hired cargo delivery firms begin flying next year.

NASA, meanwhile, wants to ramp up development of a spacecraft and heavy-lift booster that can ferry people beyond the station's orbit.

Flights to take crews to the station will be handled exclusively by Russia until US firms develop spaceships capable of orbital spaceflight.

NASA is bolstering efforts by four firms -- Boeing, Space Exploration Technologies, Sierra Nevada Corp, and Blue Origin -- with technology development contracts worth $269m (€190m).

NASA hopes the new vehicles will be ready to fly in about 2015. Russia charges the United States more than $50m (€35m) per person for Soyuz capsule transportation and training.

Atlantis arrived at the station on July 10, becoming the 37th and final shuttle mission to the station. Over the past 30 years, NASA also flew 98 other shuttle missions to deploy satellites and observatories, including the Hubble Space Telescope, and to conduct research and test technologies.

Intensive

The shuttle proved to be much more complicated and labour-intensive to prepare for flight and not as safe as expected. Two orbiters were lost in accidents, killing 14 astronauts.

The end of the programme will hit central Florida, Houston, and other shuttle operational hubs hard, with thousands of engineers and technicians due to lose their jobs shortly after Atlantis lands.

"You have to come to terms with the end before you can really put on a new beginning," Mr Ferguson said. "I think once we can finally get over the fact that the shuttle is gone and its day has come, I believe we'll begin to pick up the pieces."
