The decade-long Rosetta Mission, in which the spacecraft has chased a comet across space, is about to reach "an historic and hugely exciting moment," according to one of the scientists behind the project.
Professor Richard Holdaway, director of RAL Space at the Rutherford Appleton Laboratory in Oxford, explained:
This is an historic and hugely exciting moment for the Rosetta Mission.
After 10 years of travel through space from Earth, Rosetta finally arrives at the comet and will land a unique shoe-box sized chemistry set designed and built by RAL Space and The Open University.
We are very proud of our involvement and eagerly anticipate receiving the first results.
