Ahead
the green blue planet loomed, its surface features finally settling and
falling within the resolution of the onboard cameras, new command
routines only before tested while the probe was on ground set about
changing the operation of the probe, reports about status and trajectory
relayed back to the home planet, the primitive computers on board began
testing the imaging equipment, adjusting for contrast and drift, crude
electric heating elements warmed the reactants in the fuel tanks in
preparation for orbital insertion.
The
systems onboard waited for the confirmation of a transmitted message
from the home planet, a message that would nonetheless take minutes to
travel the distance, and which would have to be adjusted for any
sensible information to be gathered.
The
orbiter continued to verify the sensors onboard, every pixel of crude
CCD’s were scrutinized for error or for damage, checks made on
circuits, and their corresponding backups. Finally the echo arrived, the
faint radio transmission received by the large dish that dominated the
sunward side of the probe, the digital stream interpreted into numbers,
and finally corrected for time differences, repeat messages were then
received stating the same, the probes fate was decided.
Gases
were leaked form their pressure vessels, combined, and ignited, the
vacuum sucked at the reaction, the stream of particles propelling the
craft on a new course, the burn only lasted a few seconds, and many
longer ones would be required to finish the maneuvers required for it
achieve its mission, but already the planet lay directly ahead, the
probes destination clear.
Soon
the gravity of the looming planet would consume the freedom of the
probe, it would no longer have enough propellant to escape its pull, and
so the destination became inevitable. |
