First Private Spaceship Will Dock at ISS
This February, the International Space Station will receive its first privately-built visitor, an unmanned Dragon capsule built by SpaceX, which eventually will carry astronauts aboard.
What's the Latest Development?
Space entrepreneurship is set to have its first real test this February when the private company SpaceX will launch a supply capsule atop its Falcon 9 rocket from Cape Canaveral Air Force Base in Florida. The capsule, which will deliver food and clothing to the six-man crew aboard the International Space Station, was partly funded by NASA in hopes of stimulating private space ventures to bring goods, and eventually astronauts, to and from space now that the space agency's shuttle program has been retired.
What's the Big Idea?
If the US is to retain an ambitious space program, the initiative must come from the private sector, which can generally deliver goods and services for less money than government-run programs. It is hoped that the new SpaceX capsule will provide an inexpensive replacement to the shuttle program, both by taking American astronauts to and from space (a task which NASA currently outsources to the Russian Soyuz spacecraft) and by returning cargo to Earth from the ISS, which has been impossible since the shuttles were retired.

Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.
- The new definition of a kilogram is based on a physical constant in quantum physics.
- Unlike the current definition of a kilogram, this measurement will never change.
- Scientists also voted to update the definitions of several other measurements in physics.
