Roll Out Solar Array (ROSA) External Payload:

Спойлер

Over the weekend, Robotic ground controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) to remove the ROSA payload from the Dragon Trunk and position it at the ROSA Nominal Dynamics Operations position. When at this position, the controllers mated the Orbital Replaceable Unit Tool Changeout Mechanism 2 umbilicals to the ROSA payload, applied power to it and performed the initial ROSA checkouts. They then commanded the ROSA wing to fully deploy and began the planned dynamics experiments. ROSA is a new type of solar panel that is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction, array shape changes when the Earth blocks the sun, and other physical challenges to determine the array's strength and durability.

Crew Preps for Solar Array Jettison and Dragon Departure
Posted on June 26, 2017 at 6:22 pm by Mark Garcia.


The ROSA, Roll Out Solar Array, is pictured shortly after it was jettisoned fr om the tip of the Canadarm2.

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, wh ere 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.

I'm guessing (wildly) that the ROSA array will decay at a similar rate to the ACBM shield, so will be up for order 6 months.

ISS ROSA - Roll Out Solar Array Jettison

Spaceflight101

Опубликовано: 27 июн. 2017 г.

The Roll Out Solar Array was jettisoned from the International Space Station at UTC on Monday, June 26, 2017 after failing to fully lock in place when being retracted after a week-long demonstration mission of new light-weight solar array technology that could be the answer for ever-growing power demands of satellites and deep space missions.

The jettisoning of ROSA had been provisioned for in the payload's design that allowed the array segment itself to be released from its Active Flight Releasable Attachment Mechanism in the event of any type of failure. Per the original plan, ROSA was to be retracted, locked and placed back into the trunk section of the Dragon SpX-11 spacecraft for disposal. After failing to lock in place after several attempts (documented here: ) it was decided to switch to Plan B and jettison the array on a safe departure path from ISS, allowing ROSA to decay naturally over a period of months.

The fact that ROSA had to be jettisoned will not affect the overall success of its demonstration which was geared towards validating a safe deployment, electrical characteristics and structural dynamics in the deployed state.

Roll Out Solar Array (ROSA):

Спойлер

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.

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.

Спойлер

A crewmember collected Flight Day 60 urine and blood samples yesterday and today for Biochem Profile and blood and air samples for Marrow.
 

[/li]
• 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.

Aging and Heart Research Lead Station Science Today
Posted on June 27, 2017 at 3:45 pm by Mark Garcia.


Astronaut Peggy Whitson floats inside Japan's Kibo laboratory module.

Expedition 52 explored the aging process in space today and measured the lighting conditions on the International Space Station. The crew is also getting spacesuits ready for an upcoming Russian spacewalk.

Flight Engineer Peggy Whitson swapped out stem cell samples today inside the Microgravity Science Glovebox for the Cardiac Stem Cells study. The experiment is researching spaceflight's effect on accelerated aging and may provide a treatment for heart disease on Earth. Scientists are observing the stem cells in space to determine their role in cardiac biology and effectiveness in tissue regeneration.

Whitson also set up light meters to measure the intensity and color of new LED (light-emitting diode) light bulbs installed in the station. The data is being collected for the Lighting Effects study to determine how the new lights affect crew sleep, circadian rhythms and cognitive performance.

NASA astronaut Jack Fischer checked out Russian Orlan spacesuits with Commander Fyodor Yurchikhin this morning. The spacesuit maintenance work is doing being done ahead of a Russian spacewalk planned for later this year.
