NASA Space Station On-Orbit Status 26 June 2017 - Roll-Out Solar Array (ROSA) Update.

An experimental solar array demonstration was jettisoned while the Expedition 52 crew continued preparing the SpaceX Dragon for its release on Sunday. The three crew members also studied how microgravity impacts their bodies.

Following a week of successful science operations on the experiment for the Roll-Out Solar Array (ROSA), attempts to retract the array were unsuccessful. The ISS Mission Management Team met Monday morning and made the decision to jettison ROSA directly from its location at the end of the space station's robotic arm, where it remained fully deployed in a normal configuration.

The original plan called for ROSA to be stored back inside the trunk of SpaceX's Dragon which is detached and burned up in the atmosphere during Dragon reentry. The Operations team executed the jettison procedure that was developed as part of the pre-flight planning process that covered various scenarios. Once jettisoned, ROSA will not present any risk to the International Space Station and will not impact any upcoming visiting vehicle traffic.

ROSA is an experiment to test a new type of solar panel that rolls open in space and is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction, shape changes when the Earth blocks the sun, and other physical challenges to determine the array's strength and durability.

The SpaceX Dragon cargo craft is one week away from departing the International Space Station. NASA astronaut Peggy Whitson continued packing Dragon this morning with used hardware and research samples for analysis back on Earth. Dragon will be released from the Canadarm2 Sunday at 11:38 a.m. EDT and splash down in the Pacific Ocean about 5-1/2 hours later.

Whitson then joined Flight Engineer Jack Fischer in the afternoon to wrap up the Seedling Growth-3 experiment. The botanical study is exploring how the lack of gravity impacts light sensing and growth in plants. Plant samples from the study will be returned to Earth on Sunday inside the Dragon resupply ship.

Commander Fyodor Yurchikhin, along with Whitson and Fischer, took body measurements today to help scientists understand how living in space affects body size. The crew also collected blood, urine, saliva and breath samples for more insight on astronaut health.

On-Orbit Status Report

Roll Out Solar Array (ROSA): On Sunday, three attempts to retract ROSA solar array were unsuccessful. Imagery showed the array was not lining up correctly ("telescoping"), preventing the locking of ROSA's latches which is required for return in Dragon. Teams met and agreed to stand down on further retraction attempts due to the risk of getting stuck in an off nominal configuration with a partially retracted array. ROSA was left fully deployed following the last attempt and jettison was approved which was completed today at 4:15PM CDT to the nadir and aft of ISS.

Seedling Growth 3: The crew completed the second of two six-day growth sessions for Seedling Growth 3 today. They removed Experiment Containers from the European Modular Cultivation System (EMCS), processed the samples, and stowed them in the Biolab Thermal Control Unit. The samples from this and the previous run will be returned on SpaceX-11. This is the third part of the Seedling Growth Experiment series using the small flowering plant Arabidopsis thaliana to investigate the effects of gravity on the cellular signaling mechanisms of light sensing in plants (phototropism), and to investigate cell growth and proliferation responses to light stimulation under microgravity conditions.

Microbial Tracking-2 (MT-2): Yesterday the crew collected saliva samples for the Microbial Tracking-2 investigation and placed them in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). MT-2 monitors the different types of microbes that are present on ISS over a 1 year period. 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 in order to understand the microbial flora diversity on the ISS and how it changes over time.

Human Research Program (HRP): A crewmember collected Flight Day 60 urine and blood samples yesterday and today for Biochem Profile and blood and air samples for Marrow.

The Biochem Profile experiment tests blood and urine samples obtained from astronauts before, during and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results which scientists can use in their study of the effects of spaceflight on the body.
The Marrow investigation identifies the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on blood cell production in bone marrow.
