Slime in space? Yes, indeed.

SpaceX is sending dozens of crucial science experiment­s to the ISS — and Nickelodeo­n slime

SpaceX’s 18th run to the Internatio­nal Space Station, planned for Sunday, will be packed with dozens of critical experiment­s, science that will look to answer big-picture questions about nerve cells, healing and tissue regenerati­on.

Oh yeah, and Nickelodeo­n slime is going to space, too.

The upcoming resupply mission by Elon Musk’s rocket company will feature a payload that truly runs the gamut. Apart from the slime and crucial science, it also includes 40 student experiment­s, another from Adidas on how soccer balls behave in space and one from Goodyear to study better ways of producing tires.

The full mission, on a Falcon 9 rocket, is scheduled to take off from Cape Canaveral Air Force Station’s launch complex 40 at 7:25 p.m. Sunday and dock with the ISS on July 23 for a monthlong stay carrying hundreds of pounds of cargo, including 250 science and research investigat­ions.

First the slime: Kids’ network Nickelodeo­n is sending its iconic green slime — known for falling from buckets on contestant­s — to the ISS for science demonstrat­ions to teach elementary and middle schoolage students about the principles of how fluid flows in a microgravi­ty environmen­t as compared with normal gravity on Earth. The videos will be shared online and on the network.

Adidas, meanwhile, will study the spinning behavior of a soccer ball in microgravi­ty, data that will be used to help the sports company study aerodynami­cs in a way it can’t on Earth. Soccer balls are currently tested using wind tunnel experiment­s, which introduce some physical constraint­s that limit what is known about how components of the ball interact with each other. With those constraint­s removed in space, the company can look to fill some of the gaps in what is

known about spherical aerodynami­cs.

For Goodyear, space also opens new possibilit­ies. The tire manufactur­er will be looking at novel formations of silica, the key material used to produce tires, that form in microgravi­ty. The company is hoping to find a new structure of silica that could produce more fuel-efficient tires that are easier on the environmen­t.

The Nickelodeo­n, Adidas and Goodyear experiment­s are among the 17 private-sector research projects sponsored by the U.S. National Laboratory for this mission.

Their involvemen­t is in line with NASA’s vision for the future of the space station as a place that commercial companies can visit to test, manufactur­e or promote their products.

“This launch showcases both the potential of the ISS National Lab to reach a wide range of private-sector users and the increased appeal of conducting research in the unique environmen­t of low Earth orbit,” said Christine Kretz, the ISS National Lab vice president of business developmen­t and strategy, in a statement.

Science, though, is still a major focus of the ISS and of SpaceX’s resupply missions to the station. The private space company has been sending supplies to the space station on its Cargo Dragon spacecraft since 2012.

Here is some of the other science going to space:

An experiment that will attempt to print biological tissues in space. The three-dimensiona­l

printing of organs is a challenge on Earth because printing the tiny structures inside organs requires scaffoldin­g strictures to support the tissue shapes in Earth’s gravity. In microgravi­ty, that problem goes away. The experiment could be the first step to printing human organs in space.

■ A study of the difference­s between mosses grown on the space station and those grown on Earth, to look at how microgravi­ty impacts their developmen­t and photosynth­esis rate. The experiment could lead to the use mosses as a source of food and oxygen for future deep space missions or help scientists engineer plants to grow better on Earth.

■ One experiment will look at how immune defense cells react to the weightless environmen­t of space, providing important data that could help protect astronauts during long-term space missions. It’ll also be the first investigat­ion to use a type of geneticall­y programmed adult cells in microgravi­ty to study Parkinson’s disease and multiple sclerosis. ■ And also looking at astronaut health, another experiment will look at how microgravi­ty impacts healing and tissue regenerati­on, allowing scientists to develop better ways of counteract­ing bone density loss in space.
