NASA Space Station On-Orbit Status 26 May, 2020 - Anticipating Arrival of Two Astronauts on SpaceX Crew Dragon.

The Expedition 63 crew is getting ready for the launch and arrival this week of two NASA astronauts from U.S. soil for the first time in nearly a decade.
This follows Monday morning’s arrival of a Japanese cargo craft that delivered over four tons of food, supplies and experiments to the International Space Station.

NASA and SpaceX managers completed their readiness reviews and have given the “go” for the launch of Commercial Crew astronauts Bob Behnken and Doug Hurley aboard the SpaceX Crew Dragon spacecraft. The duo will liftoff atop the Falcon 9 rocket on Wednesday at 4:33 p.m. from Kennedy Space Center in Florida toward the station.

They will dock on Thursday at 11:39 a.m. to the Harmony module’s International Docking Adapter on the space station’s forward section. Two-and-a-half hours later the hatches will open, Behnken and Hurley will enter the station and the Expedition 63 crew will expand to five members to bring space research up to full speed aboard the orbiting lab.

The Crew Dragon will be docked adjacent to the newly-arrived H-II Transfer Vehicle-9 (HTV-9) from Japan. The HTV-9 was installed to the Harmony module’s Earth-facing port a couple of hours after it was captured Monday at 8:13 a.m. with the Canadarm2 robotic arm. NASA Commander Chris Cassidy began unloading the HTV-9 with help from Roscosmos Flight Engineer Ivan Vagner shortly after its arrival on Memorial Day.

The final mission of Japan’s expendable resupply ship will stay at the station until late July. Japan’s next version of resupply ships (HTV-X) will be returnable and reusable providing more cargo capabilities.

Veteran cosmonaut Anatoly Ivanishin swapped out more fuel bottles inside the Combustion Integrated Rack to maintain research operations inside the U.S. Destiny laboratory module. The refrigerator-sized research rack enables fuel, flame and soot research in microgravity.

On-Orbit Status Report


Advanced Combustion via Microgravity Experiments (ACME): The crew replaced Nitrogen/Oxygen manifold bottles in support of the continuing s-Flames investigation. The ACME experiment series being performed in the Combustion Integrated Rack (CIR) includes five independent studies of gaseous flames. The primary goals of ACME are to improve fuel efficiency and reduce pollutant production in routine fuel combustion activities on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability.

Hourglass: The crew swapped out the SD data card from PL Control Box S/N 002 to allow ground teams to continue data downlink. Hourglass investigation examines the relationship between gravity and the behavior of granular materials such as regolith that covers the surface of planets and planetary-like bodies. Researchers observe various granular materials inside an hourglass and a measuring cylinder under different gravity conditions. Better understanding of the behavior of these materials supports the design of spacecraft for future missions landing on the surfaces of planets and other celestial bodies.

Multi-use Variable-g Platform (MVP): The crew replaced the hard drive inside the Multi-use Variable-g Platform 1 in preparation of Cell-03 operations. The commercially developed, owned and operated Techshot MVP includes 2 internal carousels that simultaneously can produce up to 2 g of artificial gravity. MVP is used to conduct research in space with a wide variety of sample types, such as fruit flies, flatworms, plants, fish, cells, protein crystals and many others.


HII Transfer Vehicle (HTV)9 Cargo Operations: Today, the crew began HTV9 cargo transfer operations by unloading cargo from the HTV corridor. The vehicle delivered four tons of supplies, parts, and experiment hardware.

HTV Rendezvous Hardware Tool Cleanup: As part of closeout ops from HTV9 capture/berthing, the crew returned the Centerline Berthing Camera System (CBCS) and Vestibule Outfitting Kit (VOK) today to their appropriate stowage locations. The CBCS supports Common Berthing Mechanism (CBM) mating alignment operations necessary to berth a vehicle to Node 2. The VOK is a toolkit the crew uses during berthing operations.
