I am not so sure the accomplished very much with our current International Space Station, and yet NASA is now proposing a second station. This new station, called the "gateway spacecraft," would be located on the far side of the moon at the Earth-Moon Lagrange Point 2, approximately 38,000 miles from the moon and 277,000 miles from Earth. At this spot the spacecraft would be in an equilibrium between the Earth and moon, thereby requiring little energy to remain in place. Construction would begin sometime around 2019.
And what would this new station do? Presumably it will serve as a way-station for trips to the moon and Mars. Now that sounds a little more intriguing than simply circling the Earth, which can be done by any satellite. Mark K. Matthews in the Orlando Sentinel writes:
Potential missions include the study of nearby asteroids or dispatching
robotic trips to the moon that would gather moon rocks and bring them
back to astronauts at the outpost. The outpost also would lay the
groundwork for more-ambitious trips to Mars' moons and even Mars itself,
about 140 million miles away on average...
It gives purpose to the Orion
space capsule and the Space Launch System rocket, which are being
developed at a cost of about $3 billion annually. It involves NASA's
international partners, as blueprints for the outpost suggest using a
Russian-built module and components from Italy. And the outpost would
represent a baby step toward NASA's ultimate goal: human footprints on
Mars.
This is encouraging, if funding can be located. What is interesting is that I am seeing very little discussion outside of the Orlando story. I hope to learn more about this story and this possibility.

The International Space Station can be seen as a small object in upper

over the Houston area flying at an altitude of 390.8 kilometers (242.8
miles). The space station can occasionally be seen in the night sky with
the naked eye and a pair of field binoculars.
