O'Keefe was responding to a questioner who cited statements by shuttle program director Ron Dittemore that nothing could have been done to help Columbia and its crew even if Mission Control had been certain that thermal protection tiles on the space shuttle had been damaged.
Russia takes over shuttling.

With the space shuttle fleet grounded by the Columbia disaster, Russian spacecraft will be used to exchange crew members aboard the International Space Station, NASA officials said. The next crew to live on the station will have two members instead of the usual three and will be launched in late April or early May. The crew - one American and one Russian - will deliver a fresh Russian Soyuz, the space station's lifeboat.

The silicate grains were bound up within interplanetary dust particles collected from high up in the Earth's atmosphere using a modified spy plane. "The stardust grains we discovered are typical of the kinds of dust that were available at the beginning of our Solar System; these were the building blocks of the Sun and the planets," says Lindsay Keller, a US space agency (Nasa) co-researcher on the study.
