Engineers Excited by EuTEF's Return on Discovery

When Fabio Tominetti and Marco Grilli last saw the EuTEF research platform in early 2008, it was carefully packed inside the payload bay of space shuttle Atlantis. It had been built and handled with the utmost care, and its white and thermal insulation and golden reflective sheets and experiments were pristine.

EuTEF didn’t look much different as it hung upside down in a work stand a few days after coming back to Earth aboard Discovery following about a year and a half attached to the orbiting International Space Station.

"It’s almost brand new," said Tominetti, the EuTEF program manager for the Milan-based Carlo Gavazzi Space. "It could probably fly again tomorrow. I expected to see something to tell you that it had been exposed to 18 months in space."

EuTEF is short for European Technology Exposure Facility, a remote-controlled base complete with power and communications networks built to host nine experiments from Europe’s scientific community, including prestigious universities and foundations. The research largely focused on the effects of space on materials, including window materials that could be used on future spacecraft.

Tominetti and Grilli, a systems engineer with Carlo Gavazzi, recently traveled to NASA's Kennedy Space Center in Florida to pack the research platform and its experiments for their return to Europe.

The EuTEF went into space with the European Space Agency’s Columbus laboratory module as part of the STS-122 mission in February 2008. After Columbus was connected to the space station, spacewalking astronauts attached EuTEF to one of its platforms on the outside.

From there, the experiments would be exposed to the harshness of a constant vacuum, a round-the-clock dose of radiation, and heat and cold extremes that vary 200 degrees during each 90-minute orbit of the planet.
