Explanation:
In this alluring time exposure,
star trails arc across
the night sky above Monterey Bay and the lights of Santa Cruz,
California, USA.
But since the exposure began around 3:01am PDT on July 15
it also records the long trail of a
Delta II rocket lofting
NASA's Aura
spacecraft into Earth orbit.
Watching from a vantage point about 200 miles north of the
Vandenberg Air Force Base
launch site, photographer Rick Baldridge reports that the
trail represents the first five minutes of the
rocket's powered
flight with the ignition of additional solid fuel strap-on motors
visible after liftoff, near the beginning of the track.
The rocket trail ends at first stage shutdown.
Seen under the rocket's path,
the two brightest star trails mark the alpha and beta stars
of the high-flying
constellation Grus.
The Aura spacecraft's
goal is a comprehensive study of
planet Earth's nurturing atmosphere.
