Watch live: SpaceX to launch ISS resupply mission

Dec. 4 (UPI) — After launching 64 miniature satellites into orbit on Monday, a new record, SpaceX is scheduled to execute another rocket launch on the opposite side of the country, a resupply mission for NASA and the International Space Station.

SpaceX’s Falcon 9 rocket is scheduled to blast-off from Cape Canaveral on Tuesday. The rocket will shepherd the company’s Drago cargo ship into space.

Tuesday’s launch is scheduled for 1:38 p.m. ET. The blastoff will be broadcast live on NASA TV.

Dozens of science experiments, organized by both NASA and the ISS National Lab, are packed into the cargo ship, as are supplies and equipment for crew members aboard the space station. The payload weighs more than 5,600 pounds.

One of the new science tools being carried to ISS is a space laser designed to help scientists build a 3D map of Earth’s temperate and tropical forests. The so-called Global Ecosystem Dynamics Investigation will help climate scientists more accurate quantify the effects of deforestation on global carbon emissions.

Researchers are also sending microscopic worms to the space station to study muscle loss. The experiment could inspire new therapies for muscular dystrophy and diabetes.

Several startup companies have experiments traveling to the space station thanks to the work of ISS National Lab.

One of those experiments is designed to test the efficacy of a wound-healing technology. The investigation was designed by Elaine Horn-Ranney and her biomedical company Tympanogen. The space station’s microgravity environment will allow Horn-Ranney to precisely measure the ability of her novel hydrogel to promote healing and fend off infection-causing bacteria.

ISS National Lab also works with other federal agencies to locate experiments that might benefit from a microgravity environment. One of these is a tissue chip project designed by Sonja Schrepfer, a researcher from the University of California, San Francisco. Schrepfer’s investigation aims to measure the impacts of microgravity on the human immune system.

“The chip experiments feature small microscope-sized devices, slides measuring 1 by 3 inches or so, that can be populated with different human cell types,” Michael S. Roberts, deputy chief scientist at ISS National Lab, told UPI last month. “If you create the right environment and feed the cells the right stuff, you can guide them into behaving like specific human tissues and even whole organs.”

The 2,200 pounds worth of experiments, in addition to tools and supplies, will arrive just a day after a trio of new astronauts were welcomed to the space station. The new crew members will assist in the docking of the Dragon cargo ship.
