Mission Summary

In the days before GPS and modern navigation technology, sailors and explorers had only the stars in the night sky to guide them home. During these crucial pioneering days, star charts and sky maps were created and eventually distributed.

Today’s technology allows us to view these stars, constellations, nebulae, and countless stellar objects more up close and personal.

For the Atlas Expedition (PEP-4), STARFLEET mission specialists each pick a single object to observe and study for thirty days, such as the Moon, Sun, a planet, a star in any constellation, a nebula, and more.

Questions to Explore

How bright is the object? How big is it? What color is it? Are there any asteroids close by? What changes did you notice from day 1 to day 30?

These answers and more are uncovered during the fourth mission of the Pathfinders Expedition Program.
