WASHINGTON, Oct. 1 (UPI) -- The U.S. space agency says its Messenger spacecraft will make the second of three flybys of Mercury next week to collect more science data.
The National Aeronautics and Space Administration spacecraft is to pass 125 miles above Mercury, taking more than 1,200 pictures. NASA said the flyby also will provide a critical gravity assist needed for the probe to become, in March 2011, the first spacecraft to orbit Mercury.
