Demo Sat

Demo Sat

Ratsat, or DemoSat, was a 165-kilogram (363-pound) non-functional boilerplate spacecraft used as a mass simulator on the fourth flight of the Falcon 1 rocket.

Ratsat was carried to orbit on the the first successful orbital launch of any privately funded and developed, liquid-propelled carrier rocket, the SpaceX Falcon 1. The launch, identified as Falcon 1 Flight 4, was conducted by SpaceX, and marked the first time the Falcon 1 rocket successfully achieved orbit, after three consecutive failures on the three previous launch attempts.

Ratsat remained bolted to the second stage of the carrier rocket after reaching low Earth orbit. It has a hexagonal prism shape, 1.5 m (5 ft) long. SpaceX co-founder Elon Musk estimates that Ratsat will remain in orbit for between five and ten years before burning up in the atmosphere.

Famous quotes containing the word sat:

    He sat in a wheeled chair, waiting for dark,
    And shivered in his ghastly suit of grey,
    Legless, sewn short at elbow.
    Wilfred Owen (1893–1918)
