Roll-Out Solar Array Experiment (ROSA) Deploys on International Space Station

NASA Johnson

Опубликовано: 19 июн. 2017 г.

The Roll-Out Solar Array (ROSA) was deployed from the end of the Canadarm2 robotic arm Sunday, June 18 outside the International Space Station. ROSA is an experiment to test a new type of solar array that rolls open in space like a party favor and is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction,characterizes changes when the Earth blocks the sun, vibration and other physical challenges to determine the array's strength and durability. ROSA has the potential to replace solar arrays on future satellites, making them more compact and lighter weight. Satellite radio and television, weather forecasting, GPS and other services used on Earth would all benefit from high-performance solar arrays. The payload will remain deployed for seven days before retracting and will be stowed back inside the trunk of SpaceX's Dragon cargo vehicle. Note: footage of deploy is sped up 300%.

Changing How Solar Power Rolls


The Roll-Out Solar Array (ROSA) was deployed from the end of the Canadarm2 robotic arm Sunday, June 18 outside the International Space Station. ROSA is an experiment to test a new type of solar array that rolls open in space like a party favor and is more compact than current rigid panel designs.

Traditional solar panels used to power satellites can be bulky with heavy panels folded together using mechanical hinges. An experiment that recently arrived at the International Space Station will test a new solar array design that rolls up to form a compact cylinder for launch with significantly less mass and volume, potentially offering substantial cost savings as well as an increase in power for satellites.

Smaller and lighter than traditional solar panels, the Roll-Out Solar Array, or ROSA, consists of a center wing made of a flexible material containing photovoltaic cells to convert light into electricity. On either side of the wing is a narrow arm that extends the length of the wing to provide support, called a high strain composite boom. The booms are like split tubes made of a stiff composite material, flattened and rolled up lengthwise for launch. The array rolls or snaps open without a motor, using stored energy from the structure of the booms that is released as each boom transitions from a coil shape to a straight support arm.

ROSA can be easily adapted to different sizes, including very large arrays, to provide power for a variety of future spacecraft. It also has the potential to make solar arrays more compact and lighter weight for satellite radio and television, weather forecasting, GPS and other services used on Earth. In addition, the technology conceivably could be adapted to provide solar power in remote locations. The technology of the booms has additional potential applications, such as for communications and radar antennas and other instruments.

The ROSA investigation looks at how well this new type of solar panels deploys in the microgravity and extreme temperatures of space. The investigation also measures the array's strength and durability and how the structure responds to spacecraft maneuvers.

"When the array is attached to a satellite, that spacecraft will need to maneuver, which creates torque and causes the wing, or blanket, to vibrate," explains principal investigator Jeremy Banik, senior research engineer at the Air Force Research Laboratory, Kirtland Air Force Base in New Mexico. "We need to know precisely when and how it vibrates so as not to lose control of the spacecraft. The only way to test that is in space."

The investigation will monitor the array deployed in full sun and full shade and collect data on how much it vibrates when moving from shade to light. This vibration, known as thermal snap, could present challenges in operating satellites with sensitive functions, and the researchers want to learn how to avoid those challenges with ROSA.

"This structure is very thin, only a few millimeters thick, and heats up very quickly, dozens of degrees in a few seconds," Banik says. "That creates loads in the wing that could cause it to shudder. That would create problems, for example, if a satellite was trying to take a picture at the same time."

The investigation will measure power produced by the array to see how ROSA's thin, crystalline photovoltaic cells hold up during launch. In addition, researchers want to see how the array handles retraction.

"We want to show that we can pull the wing back in in a predictable way," Banik says. "A practical reason is that we have to pull it back for stowage after this investigation, but it will be good to know it can be done for future applications, potentially for a highly maneuverable spacecraft."

The intent of this investigation, Banik explained, is to compare on-orbit ROSA data to model predictions previously validated by on-ground measurements in a simulated environment.

"Recognize that we are trying to learn how it behaves – this is an experiment and not a demonstration – so we'll glean useful data even if it doesn't behave the ways we expect," Banik said.

Investigators on the ground will initiate video of deployment and retraction, and sensors embedded on the array will record data on photovoltaic performance, temperature, and accelerations.

"When launching into space, mass and volume are everything, and ROSA is 20 percent lighter and four times smaller in volume than rigid panel arrays," Banik says. "You realize big cost savings from shaving off a little mass and volume, which makes it possible to raise bandwidth on a communications satellite and, for example, make GPS more accessible and reliable for everyone."

In other words, this little array could really change how solar power rolls.

ROSA was developed as part of the Solar Electric Propulsion project sponsored by NASA's Space Technology Mission Directorate. NASA tested the ROSA technology in vacuum chambers on Earth several years ago, and this is its first test in space. This solar array technology was developed to power large spacecraft using highly-efficient electric propulsion on missions to deep space including Mars and the moon.

The Roll Out Solar Array, also known as ROSA, was deployed June 18 from the tip of the Canadarm2.

[свернуть]

Robotics controllers completed the unloading and set up of the third and final external experiment delivered last week aboard the SpaceX Dragon resupply ship. Inside the International Space Station, the Expedition 52 crew studied a variety of life science including plant growth, bone loss and cardiac biology.

Over the weekend, engineers on the ground remotely operated the Canadarm2 to extract the Roll Out Solar Array from Dragon.  The experiment, also known as ROSA, will remain attached to the Canadarm2 over seven days to test the effectiveness of the advanced, flexible solar array that rolls out like a tape measure.

Flight Engineer Jack Fischer and Peggy Whitson set up the Seedling Growth-3 botany study today that is researching how plant cells respond to lighting conditions in microgravity. Fischer also installed samples in a NanoRacks facility for an educational research project that is studying the effects of radiation damage on synthetic DNA.

Whitson measured bone loss in mice for the Rodent Research-5 study. Results may improve the health of astronauts living in space and humans on Earth with bone diseases. Whitson later moved onto the Cardiac Stem Cells experiment that seeks to understand the accelerated aging process that takes place in space.

Dragon Packing and BEAM Checks Onboard Station Today

Posted on June 20, 2017 at 3:28 pm by Mark Garcia.


NASA astronauts Peggy Whitson and Jack Fischer are pictured packing up gear inside the International Space Station.

The Expedition 52 crew is loading the SpaceX Dragon with cargo for return back to Earth in less than two weeks. BEAM, the experimental habitat, also received a new radiation shield today that was 3D printed aboard the International Space Station.

Dragon is due to leave the International Space Station July 2 after cargo transfers with the resupply ship are complete. The crew offloaded new science experiments, spacewalking gear and station hardware shortly after it arrived on June 5. Dragon will now be packed with used station gear and research samples for analysis by NASA engineers and scientists after it splashes down in the Pacific Ocean.

Flight Engineer Jack Fischer opened up BEAM today and entered the expandable activity module for a regular checkup. He replaced an older radiation shield with a thicker shield that covers a radiation sensor inside BEAM. Fischer also sampled BEAM's air and surfaces for microbes.

Veteran astronaut Peggy Whitson of NASA spent Tuesday sampling the air and surfaces for microbes in the station's U.S. segment. Whitson also spent some time stowing synthetic DNA samples exposed to radiation in a science freezer and began readying rodent research gear for return next month aboard Dragon.

The Multiple User System for Earth Sensing Facility (MUSES) will inspire and enable numerous branches of research and science through its ability to support many different kinds of investigations and hardware aboard the International Space Station. Providing a platform for payloads such as high-resolution digital cameras and hyperspectral imagers, MUSES provides precision pointing and other accommodations for various kinds of research and science.

Orbiting approximately 250 miles above the Earth, the MUSES platform offers researchers a unique vantage point from the outside of the station for tasks like Earth observation, disaster response, maritime domain awareness, agricultural/land use applications, food security, air quality, oil and gas exploration, mining, atmospheric investigations, and fire detection.

Спойлер

"The space station's path is ideal for Earth science," said Paul Galloway, the project's manager and lead systems engineer. "The repeated exposure to the Earth's land masses gives you a good revisit time for target areas. MUSES' ability to point and track ground targets also enhances the revisit opportunities and viewing angles."

The space station's orbit cover's 90% of the Earth's inhabited surfaces and allows for both day and nighttime passes, allowing a variety of observation and data collection times.

MUSES will provide Earth imagery data to NASA's SERVIR team to provide disaster response information to aid in the team's humanitarian missions, improving environmental decision-making among developing nations. The MUSES payload data can be used in response to disasters world-wide.

Instruments flying aboard the platform will be able to detect phenomenon like flooding, coastal erosion, water pollution, red tide, and landslides. Space-based imagery is one of many tools used in the disaster response decision-making process.

The MUSES platform is a U.S. National Laboratory sponsored pointing system and can accommodate up to four instruments at a time. Each instrument can be installed and removed robotically. These payloads can be operated simultaneously, triggering a system that can communicate with all the systems aboard the space station and store and transmit large amounts of data back to the ground.  The system will be operated from the Teledyne Operations Center in Huntsville, Alabama.

Developed in a cooperative agreement between Teledyne Brown Engineering and NASA, MUSES will provide many commercial companies the opportunity to conduct their science and research in space.

MUSES provides low-cost access to space for instrument developers.  MUSES and the ability to return payloads from the space station to Earth provides an excellent platform for technology demonstration and the space qualification of hardware.

"Unlike the Earth views from ISS's internal viewing windows which are somewhat limited by surrounding structure, the view to the Earth from the ISS truss is essentially unobstructed," said Galloway.

The first investigation to be hosted aboard the MUSES platform will be the DLR Earth Sensing Imaging Spectrometer (DESIS), on Expeditions 51/52 and 53/54, and is planned for launch later this year. DESIS is a hyperspectral imager operating in the 400-1000 nanometer spectral range. "The German Space Agency, DLR, will use the DESIS imagery for scientific purposes.  Teledyne Brown Engineering will use the imagery for commercial purposes," according to Galloway.

"MUSES was designed to interface with every possible data network on ISS and take maximum utilization of the downlink capability from ISS to ground to achieve our goal of getting large amounts of image and scientific data down from these instruments," said Galloway.

CASIS Partnership Brings "Organs-on-Chips" Research to Space Station

Models of human disease are beneficial for medical research, but have limitations in predicting the way a drug will behave within the human body using data fr om non-human models because of inherent differences between species. Many medications produce unexpected outcomes in the clinical trial stage using human subjects, despite success in animal models and even 2-D cell culture models using human cells. The "Organs-on-Chips" approach to human physiology research aboard the International Space Station may lead to more reliable and predictable results for drug development and reduce the need for animal testing.

Five recently announced research projects funded by the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health (NIH), and sponsored by the Center for the Advancement of Science in Space (CASIS), will soon bring "Organs-on-Chips" research to the orbiting laboratory.

Conducting biomedical investigations within the space station's unique microgravity environment allows researchers to study cells as they grow in 3-D, rather than in the 2-D lab environment on Earth wh ere gravity forces cells in culture to flatten against plastic walls. In addition to the advantages of growing cells into 3-D tissues, cell cultures will also be observed for changes in gene expression, cell communication, and patterns of differentiation that may lead to changes in organs and other body systems.

The research projects include:

[/li]
• Lung Host Defense in Microgravity (George Worthen, Children's Hospital of Philadelphia)
• Organs-on-Chips as a Platform for Study the Effects of Microgravity on Human Physiology: Blood-Brain Barrier-Chip in Health and Disease (Christopher Hinojosa, Emulate, Inc.)
• Cartilage-Bone-Synovium Microphysiological System: Musculoskeletal Disease Biology in Space (Alan Grondzinsky, MIT)
• Microgravity as a Model for Immunological Senescense and its Impact on Tissue Stem Cells and Regeneration (Sonja Schrepfer, UCSF)
• Effects of Microgravity on the Structure and Function of Proximal and Distal Tubule Microphysiological System (Jonathan Himmelfarb, U of Washington)

Partnerships like the one between CASIS and NCATS at NIH provide scientists and engineers the unique opportunity to fly their science in space, furthering ground research and bringing space closer to home than ever.

 "The International Space Station is a unique platform for research innovation capable of benefitting life on Earth, but it also has the ability to foster valuable partnerships that enable experimentation for a variety of investigators," said Patrick O'Neill, marketing and communications manager at CASIS.

"This partnership with the NCATS is part of a multi-year collaboration that will provide investigators the resources required to enhance this burgeoning new research discipline some 250 miles above Earth."

Crew Researching Mice and Microbes to Understand Human Impacts

Posted on June 21, 2017 at 3:13 pm by Mark Garcia.

The three orbiting crew members living on the International Space Station today explored the effects of microgravity on mice and microbes to understand how living in space impacts humans. Cargo transfers are also underway on the orbital complex after the arrival of the latest resupply ship.

A pair of life science experiments observing mice are being worked today to research how the weightless environment of space impacts bones, muscles and the immunity system. For the Rodent Research-5 study today, NASA astronauts Peggy Whitson and Jack Fischer observed how drug therapies on mice may offset the negative health impacts of spaceflight. The duo also set up gear for a new study, the Multi-Omics Mouse experiment, which will be launched on the next Space Dragon mission and will evaluate the impacts of space environment and prebiotics on astronauts' immune function.

The crew also collected saliva samples and stowed them in a science freezer for later microbial analysis on Earth. Station surfaces were also swabbed and air samples were taken to help scientists identify the microbes living on the station and how they may change on orbit.

Expedition 52 Commander Fyodor Yurchikhin continued unloading the 3,000 pounds of food, fuel and supplies delivered last week aboard the Progress 67 resupply ship. The veteran station cosmonaut also had some time set aside to update the station's inventory system and check on Russian science experiments.

Expedition 52 is continuing to explore a new drug therapy today that may keep humans healthier in space. The trio onboard the International Space Station also worked on standard maintenance activities to keep the orbital complex in ship-shape.

Astronauts living on the station exercise a couple of hours every day to offset the muscle and bone loss experienced in microgravity. A new injectable drug is also being explored as a way to maintain strong bones during spaceflight. Flight Engineers Peggy Whitson and Jack Fischer of NASA are testing that drug today on mice for the fifth version of the ongoing Rodent Research experiment. Rodent Research-5 is testing the drugs ability to stop and reverse bone loss in space and may help patients with bone disease on Earth.

Fischer also worked on light plumbing duties and microbe sampling throughout Thursday. Whitson also worked on microbe sampling and set up life science gear ahead of a new experiment to be delivered on the next SpaceX Dragon cargo mission.

Commander Fyodor Yurchikhin checked out Russian life support gear and continued unloading new gear delivered last week inside the Progress 67 (67P) resupply ship. The veteran cosmonaut also repressurized the station's atmosphere using oxygen stored inside the 67P.

Expedition 52 crew members Fyodor Yurchikhin (middle foreground) and Jack Fischer were inside the Zvezda service module monitoring the docking of a Russian Progress 67 cargo ship on June 16, 2017.
 
The Expedition 52 trio worked throughout Friday on human research studying cardiac biology and the microbes that live on humans. Tiny satellites inside the International Space Station were also investigated for future remote or autonomous use in space.

NASA astronaut Jack Fisher collected microbe samples from his body and stowed them inside a science freezer for later analysis on Earth. He also activated an ultrasound and scanned his legs for the Vascular Echo study that is exploring how veins and arteries adapt during a spaceflight mission.

Three-time station crew member Peggy Whitson retrieved stem cell samples for observation to determine if living in space speeds up the aging process. Whitson then set up the SPHERES Halo experiment that is exploring the possibility of using satellites to clean up space debris and assemble objects such as space telescopes and habitats.

Commander Fyodor Yurchikhin worked in the station's Russian segment maintaining life support systems. The veteran cosmonaut also explored pain sensation in space then wrapped up the work day with Earth photography documenting human and natural impacts across the globe.
