After several decades of service, the space shuttle will be finally put down to retirement. The ship already spent 300 days in orbit and has already traveled 120 million miles.

Only two missions are left for NASA's space shuttle program. This is in accordance to the directive by the White House to end the long running space program.

Asteroid 24 Themis as a Space Gas Station?

The discovery of water compounds on the asteroid 24Themis brought a possibility of having a space gas station for manned space flights. Water can easily be converted to hydrogen fuel through a simple electrolysis or can be purified to be used as drinking water for the astronauts.

Today's space mission carries a lot of supplies from the earth (i.e water) which makes the rocket payload much heavier. Having a water supply on or along the way to the destination will be a big reduction on the weight of the space craft and the power requirement of the rocket that will carry it.

The challenge though lies in the fact that the gravity on 24 Themis is far less than that of the Earth. It will be a real challenge on how extract water from the lonely asteroid.

- Planet Venus is named after the Roman equivalent of the Greek god love, Aphrodite.
- Galileo's observance of the phases of Venus led him to conclude that the Sun and not the Earth is the center of the Solar System. This was in agreement with the findings of an earlier astronomer, Copernicus.
- Planet Venus and not Mercury is the hottest planet in the Solar System. The cause of Venus' high temperature is the greenhouse effect due to its thick atmosphere of Carbon Dioxide.
