VOYAGE TO MARS

In Earth years, it is 2076, and the now routine Voyage to Mars has brought the latest human crew into Martian orbit.  The Mars Control team has been living on Mars for two years. Anxious to get home, they direct the Mars Transport Vehicle team (their replacement crew) to arrive on the planet safely so that they are able to take over the Mars Mission.  This will allow the Mars Control team to return home Earth on schedule.

RENDEZVOUS WITH A COMET

In the not-too-distant future a team of scientists and engineers are serving as astronauts and mission controllers on a daring exploration of comets. Their goal is to plot a course to rendezvous with a comet and launch a probe to collect scientific data on the object.
