The SpaceX Dragon spacecraft is loaded with more than 5,000 pounds of supplies and experiments for delivery to the International Space Station on CRS-5 – the company’s fifth resupply mission to the ISS. One of the experiments, the Cloud Aerosol Transport System – or CATS, is designed to study the global distribution of clouds and aerosols in our atmosphere. Launch from Cape Canaveral Air Force Station is no earlier than Jan. 10.
