European Space Agency director Josef Aschbacher promised a "transformation" of the continent's space sector in the coming years during an interview with AFP, including more collaboration between government and private industry.

Private firms will be "encouraged to be a partner and not only a contractor," Aschbacher said, answering questions on the sidelines of an aerospace industry conference taking place this week in Colorado Springs, in the United States.

US space agency NASA has long incorporated private firms into its space exploration, planning to send its astronauts to commercial orbiting outposts once the International Space Station is retired.

But any major reorientation of the European space program will need to be discussed at the second European space summit, to be held in Seville, Spain, in November.

Here are Aschbacher's answers to questions posed Tuesday by AFP.

Imagine you traveled thousands of miles to see a total solar eclipse, but as the Moon began moving in front of the Sun, the sky grows cloudy, blocking your view of the unique celestial spectacle.

That's what happened to University of Hawaii astronomer Shadia Habbal—several times.

After traveling all the way to Antarctica on her latest expedition to study the inner part of the Sun's outer atmosphere—the corona—Habbal was met with clouds once again.
