After a few day’s delay due to weather conditions, the Cygnus-4 spacecraft is now enroute to the International Space Station. Aboard are the AstroPi computers and spare parts for ESA’s Biolab facility among many other cargo items – over 3000 kg worth of experiments and supplies.

The spacecraft is now flying through space and will be grappled and berthed to the Space Station on 9 December.
