PARIS, Oct. 23 (UPI) -- The European Space Agency says it will delay the launch of a galaxy-mapping spacecraft due to a technical issue with some on-board components.
The launch of the Gaia mission -- intended to survey billions of stars to create a precise 3-D map of our Milky Way galaxy -- was postponed Tuesday after a technical issue was identified in another satellite already in orbit that shares some components with the Gaia spacecraft.
