SpaceX has launched the same robotic Dragon cargo capsule to the International Space Station for a third time, sending about 5,000 pounds of cargo that includes a bag of goopy green slime.
The slime, provided by Nickelodeon, will be used on the space station to demonstrate fluid flow in zero gravity — and undoubtedly delight youngsters who’ll watch the crew poke, squish, pull and prod the green stuff in future videos.
It’s just one of the dozens of science experiments included on the manifest for SpaceX’s latest resupply mission. Other experiments will build up layers of human tissue through 3-D printing, grow moss as a potential food source in zero-G, and investigate new twists in silica deposition that could improve the performance of automobile tires.
A new docking adapter for future commercial space taxis will be delivered as well, along with more mundane supplies such as food and clothing.
