30-Jan-07 | STEREO completes lunar swing-by

NASA’s twin STEREO spacecraft have completed a delicate series of orbital manoeuvres, using the Moon’s gravity to send them into their operational orbits.  Both observatories passed the Moon on 15-Dec-06, which placed the “A” spacecraft into its orbit “ahead” of that of Earth.  The “B” spacecraft made a second lunar pass on 21-Jan-07 to enter its orbit “behind” Earth.  Controllers expect the craft to produce the first 3-D images of the Sun by April.  (JHU APL Press Release, 23-Jan-07)
