Northrop Grumman’s Antares rocket launched April 17 from the Wallops Flight Facility, Virginia, carrying the unpiloted Cygnus cargo spacecraft to orbit for its journey to deliver several tons of supplies and scientific experiments to the International Space Station. Dubbed the “SS Roger Chaffee” in honor of the NASA astronaut who died in the Apollo 1 launch pad fire in January 1967, Cygnus is scheduled to arrive at the station on April 19. It will remain at the space station until July 23, when it will depart, deploy NanoRacks customer CubeSats, and then have an extended mission in orbit until December. This will be the final mission under Northrop Grumman’s Commercial Resupply Services (CRS-1) contract with NASA before starting the CRS-2 contract missions this fall.

Expedition 59 is the 59th Expedition to the International Space Station, started on 14 March 2019 with the arrival of the Soyuz MS-12 spacecraft carrying Aleksey Ovchinin, Nick Hague and Christina Koch. Ovchinin and Hague were originally meant to fly to the ISS aboard Soyuz MS-10, but had to return minutes after takeoff due to an unforeseen anomaly. The three will subsequently transfer to the Expedition 60 crew, with Ovchinin as commander, after the undocking of the Soyuz MS-11 spacecraft, scheduled for July 2019.

Researchers on Expedition 59 will conduct experimentation on tissue chips because the microgravity environment can replicate the effects of aging and disease. The expedition will also conduct experiments on regolith stimulants and Earth’s atmospheric carbon cycle. Lastly, the expedition will also test Astrobee robots designed to conduct routine chores aboard the ISS.
