At 7:01 a.m. EDT, the S.S. Patricia “Patty” Hilliard Robertson Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm which earlier detached Cygnus from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the South Atlantic Ocean.

The Cygnus spacecraft successfully departed the space station more than five and a half months after arriving at the microgravity laboratory to deliver about 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo for NASA.

Up next, the Kentucky Re-entry Probe Experiment-2 (KREPE-2), stowed inside Cygnus, will take measurements to demonstrate a thermal protection system for spacecraft and their contents during re-entry in Earth’s atmosphere, which can be difficult to replicate in ground simulations.

Following a deorbit engine firing on Saturday, July 13, Cygnus will begin a planned destructive re-entry, in which the spacecraft – filled with trash packed by the station crew – will safely burn up in Earth’s atmosphere.

Cygnus arrived at the space station Feb. 1, following a launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. It was the company’s 20th commercial resupply services mission to the space station for NASA. The spacecraft is named the S.S. Patricia “Patty” Hilliard Robertson in honor of the former NASA astronaut.

While orbiting nearly 260 miles above the North Pacific Ocean, the International Space Station soars from orbital nighttime into orbital daytime.
While orbiting nearly 260 miles above the North Pacific Ocean, the International Space Station soars from orbital nighttime into orbital daytime.

The Expedition 71 and Boeing Crew Flight Test crews had a light duty day on Wednesday, focusing on Earth observations and station upkeep.

While soaring 250 miles above our home planet, the International Space Station passes into orbital nighttime roughly every 45 minutes. During these night periods, crew members can observe events in Earth’s atmosphere that are otherwise difficult to capture during daylight. In the morning, NASA astronaut Jeanette Epps entered the cupola to set up equipment for the Thor-Davis investigation. She then used the high-speed Davis Camera to observe and capture thunderstorms in Earth’s upper atmosphere. The camera, specially designed to track electrical activity at up to 100,000 frames per second, could be used during future missions to record processes in severe electrical storms.

In the Japanese Experiment Module, NASA astronaut Tracy C. Dyson spent most of the morning relocating the Internal Ball Camera before reactivating the hardware at its new docking station. Afterward, she audited emergency medical kits and hardware.

NASA astronaut Matthew Dominick spent most of the day in the Tranquility module to remove and replace a ventilation fan, while his crewmate, Mike Barratt, worked in the Columbus module to clear out hardware and stowage in preparation for the future installation of new exercise equipment.

Starliner Commander Butch Wilmore and Pilot Suni Williams teamed up on Wednesday to continue work on the wastewater processing system, removing and replacing a failed pressure control pump motor.

In the Roscosmos segment, Commander Oleg Kononenko and Flight Engineer Nikolai Chub began the day prepping and donning a watch that will record their movement, physical activity, and sleep over the next 36 hours. The duo then prepped for some routine flight simulation training while their crewmate, Alexander Grebenkin, observed Earth’s nighttime atmosphere in near-ultraviolet.
