NASA Space Station On-Orbit Status 26 July 2017 - T-Minus 2 Days to Expedition 52/53 Launch

The Soyuz MS-05 spacecraft that will launch three new crew members to the International Space Station has rolled out to its launch pad in Kazakhstan.

The rocket was carted slowly by train from its processing facility to the pad and vertically raised to its launch position at the Baikonur Cosmodrome.

Cosmonaut Sergey Ryazanskiy will command the Soyuz when it launches Friday at 11:41 a.m. EDT. He will be flanked by flight engineers Randy Bresnik from NASA and Paolo Nespoli from the European Space Agency. The trio will take a six-hour, 19-minute ride from Earth to the station's Rassvet module. NASA TV will broadcast the launch and docking activities live beginning at 10:45 a.m.

The three Expedition 52 crew members living on the space station now are moving right along with ongoing human research. Veteran astronaut Peggy Whitson continued exploring therapies that target only cancer cells. Flight Engineer Jack Fischer swabbed his mouth and body for a study tracking microbes in space. Station Commander Fyodor Yurchikhin worked life support maintenance and sampled the station's air for a quality check.

On-Orbit Status Report

Microbial Tracking-2 (MT-2): The crew collected saliva and body samples for the Microbial Tracking-2 investigation and placed them inside a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). After the samples are returned to Earth, a molecular analysis of the RNA and DNA will be conducted to identify the specific microbes that are present on ISS. MT-2 monitors the different types of microbes that are present on ISS over a 1-year period and how they change over time.

Efficacy and Metabolism of Azonafide Antibody-Drug Conjugates in Microgravity (ADCs in Microgravity): The crew viewed ADC cells with a microscope and fixated the BioCells. The ADCs in Microgravity investigation evaluates new antibody-drug conjugates that combine an immune-activating drug with antibodies in order to target only cancer cells, increasing the effectiveness of chemotherapy and reducing its side effects. In microgravity, cancer cells grow in three-dimensional, spheroid structures that closely resemble their form in the human body, allowing for better drug testing. This investigation may accelerate development of targeted therapies for cancer patients.

Sprint Volume of Oxygen Utilized (VO2) Maximum: The crew set up and performed a Sprint VO2 Max exercise protocol today. The subject completed their Flight Day 105 session with assistance from the other USOS crewmember. The Sprint investigation evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in ISS crewmembers during long-duration missions.

Habitability: The crew narrated a task video while they tore down the microscope hardware used for the ADCs in Microgravity investigation. The Habitability investigation collects observations about the relationship between crewmembers and their environment on the ISS. Observations can help spacecraft designers understand how much habitable volume is required, and whether a mission's duration impacts how much space crew members need.

Node 3 to Node 1 Sample Delivery Systems (SDS) Power Jumper Installation: The crew installed the SDS Power Jumper in the Node 1 to Node 3 Vestibule and mated the SDS Power Cable to the Node 3 bulkhead. This activity is part of the ISS Reconfiguration plan and is required to provide samples for the Major Constituent Analyzer (MCA) in support of visiting vehicles berthed to Node 1.
