US astronaut prepares for space mission that his brother will later join him on

US astronaut excited about upcoming space mission

BAIKONUR, Kazakhstan — When U.S. astronaut Scott Kelly blasts off to the International Space Station, he will have one unlikely consolation as he begins five months away from his family — his identical twin will drop by.

Kelly and Russia’s Alexander Kaleri and Oleg Skripochka will take off early Friday on a Russian Soyuz rocket from the Baikonur cosmodrome leased by Russia in southern Kazakhstan for a five-month mission.

Scott Kelly will be joined at the space station by his brother Mark, another NASA astronaut who will fly the Endeavor space shuttle.

“As kids, we never thought we’d be in this unique and privileged position to be able to do this,” Scott Kelly told reporters from behind a plate of protective glass. The cosmonauts are kept in strict isolation in the days ahead of the launch to avoid exposure to infection.

During the pre-launch news conference Mark Kelly looked at Scott from the other side of the glass as he sat next to journalists, engineers and NASA officials.

Mark Kelly told The Associated Press he had thought it unlikely that he and his brother would meet in space, even when they both were on space flight training programs.

This twist of fate became possible after Mark Kelly’s shuttle flight was postponed in July. “It wasn’t planned. I should have landed by now,” he said.

Scott Kelly and two Russian cosmonauts will be flying in Russia’s first all-digital Soyuz. A single new digital device on the spacecraft will replace five incompatible processors used for monitoring different aircraft systems.

The overhauled Soyuz will allow a doubling of the launch rate of Soyuz spaceships, which will help maintain a crew of six aboard the space station — crucial in the absence of the NASA shuttle fleet.

The upgrade is expected to save time in the pre-launch checkout and in overseeing the craft in space.

Kelly’s teammate, Alexander Kaleri, said it was high time to retire “last century’s technology.”

The Soyuz spacecraft was designed in the mid-1960s and is still in service, somewhat modified. It can only be used once, but costs just $25 million — while the newest, reusable Endeavor space shuttle cost $2 billion.

But the Endeavor that will bring Mark Kelly to space is the next-to-last U.S. shuttle before NASA wraps up 30 years of shuttle flight.

The U.S. Congress approved a blueprint in September to extend the life of the space shuttle program for a year, allowing one last space shuttle mission following the Endeavor flight, scheduled for February.

Kelly, who will become station commander in late November, said that that his job in space will be “dedicated to preparing in some respect for the post-shuttle era.”

Kelly, Kaleri and Stripochka will join U.S. astronauts Douglas Wheelock and Shannon Walker and Russia’s Fyodor Yurchikhin, who have been at the station since June. The six will be there to celebrate the station’s tenth anniversary on Nov. 20.

The mammoth station consists of 10 modules built by the United States, Russia, Canada, Japan and the 18-nation European Space Agency.

Preparations for Friday’s launch were marred by reports that the Soyuz rocket for the December launch was damaged while it was transported to Kazakhstan.

Vitaly Lopota, head of Energiya spacecraft maker, told reporters on Wednesday that engineers discovered damage to the spacecraft’s container, but not to the craft itself.
