CubeSats Deployed Before Upcoming Crew and Cargo Missions

Posted on May 26, 2017 at 11:48 am by Mark Garcia.


A trio of CubeSats, with Earth's limb and thin atmosphere in the background, is seen shortly after being ejected from a small satellite deployer outside Japan's Kibo lab module.

More CubeSats were ejected from the International Space Station this week to explore the Earth's upper atmosphere. Meanwhile, the Expedition 51 crew trained for a crew departure and cargo craft arrival.

NanoRacks, a private company with facilities on the space station, deployed a total of 17 CubeSats over two days this week from a satellite deployer outside the Japanese Kibo lab module. The tiny satellites will orbit Earth for up to two years observing Earth's thermosphere and studying space weather.

Two Expedition 51 crew members are returning to Earth June 2 completing a 196 day mission in space. Soyuz Commander Oleg Novitskiy and Flight Engineer Thomas Pesquet practiced their descent today in their Soyuz MS-03 spacecraft. The duo are expected to land in Kazakhstan next Friday at 10:10 a.m. EDT.

The Dragon resupply ship, from SpaceX and loaded with brand new science experiments, will launch June 1 and arrive at the station June 4. NASA astronaut Jack Fischer will be at the robotics controls commanding the Canadarm2 to reach out and grapple Dragon. He and station Commander Peggy Whitson familiarized themselves today with the Dragon capture procedures and lighting conditions inside the cupola.

Over 40 U.S. National Laboratory Sponsored Experiments on SpaceX CRS-11 Destined for the International Space Station
https://www.youtube.comwatch?v=rsAv1E4l9fE   

KENNEDY SPACE CENTER, FL. (May 26, 2017) - The SpaceX Falcon 9 vehicle is slated to launch its 11thcargo resupply mission (CRS-11) to the International Space Station (ISS) no earlier than June 1, 2017 fr om Kennedy Space Center Launch Pad 39A. Onboard the Falcon 9 launch vehicle is the SpaceX Dragon spacecraft, which will carry more than 40 ISS U.S. National Laboratory sponsored experiments. This mission will showcase the breadth of research possible through the ISS National Laboratory, as experiments range from the life and physical sciences, Earth observation and remote sensing, and a variety of student-led investigations. Below highlights the investigations as part of the SpaceX CRS-11 mission:
 
ADVANCED COLLOIDS EXPERIMENT-TEMPERATURE CONTROLLED-6 (ACE-T-6)

 Скрытый текст:

Matthew Lynch, Procter & Gamble (West Chester, OH)
Implementation Partner: NASA Glenn Research Center and Zin Technologies, Inc.

Colloids are suspensions of microscopic particles in a liquid, and they are found in products ranging from milk to fabric softener. Consumer products often use colloidal gels to distribute specialized ingredients, for instance droplets that soften fabrics, but the gels must serve two opposite purposes: they have to disperse the active ingredient so it can work, yet maintain an even distribution so the product does not spoil. Advanced Colloids Experiment-Temperature-6 (ACE-T-6) studies the microscopic behavior of colloids in gels and creams, providing new insight into fundamental interactions that can improve product shelf life.

EFFICIENCY OF VERMICOMPOSTING IN A CLOSED SYSTEM (NANORACKS-NDC-BMS-VERICOMPOSTING)

 Скрытый текст:

Bell Middle School (Golden, CO)
Implementation Partner: NanoRacks

Vermicomposting, or using worms to break down food scraps, is an effective way to reduce waste and obtain a nutrient-rich fertilizer for plants. The NanoRacks-NDC-Bell Middle School-Efficiency of Vermicomposting in a Closed System (NanoRacks-NDC-BMS-Vermicomposting) investigation is a student-designed project that studies whether red wiggler worms, a species of earthworm, are able to produce compost in space. Results are used to study the potential for composting as a form of recycling on future long-duration space missions.

FUNCTIONAL EFFECTS OF SPACEFLIGHT ON CARDIOVASCULAR STEM CELLS (CARDIAC STEM CELLS)

 Скрытый текст:

Dr. Mary Kearns-Jonker, Loma Linda University (Loma Linda, CA)
Implementation Partner: BioServe Space Technologies

Functional Effects of Spaceflight on Cardiovascular Stem Cells (Cardiac Stem Cells) investigates how microgravity alters stem cells and the factors that govern stem cell activity, including physical and molecular changes. Spaceflight is known to affect cardiac function and structure, but the biological basis for this is not clearly understood. This investigation helps clarify the role of stem cells in cardiac biology and tissue regeneration. In addition, this research could confirm the hypothesis that microgravity accelerates the aging process.

MULTIPLE USER SYSTEM FOR EARTH SENSING (MUSES)

 Скрытый текст:

Paul Galloway, Teledyne Brown Engineering (Huntsville, AL)
Implementation Partner: Teledyne Brown Engineering

Teledyne Brown Engineering developed the Multiple User System for Earth Sensing (MUSES), an Earth imaging platform, as part of the company's new commercial space-based digital imaging business. MUSES hosts earth-viewing instruments (Hosted Payloads), such as high resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations. It hosts up to four instruments at the same time, and offers the ability to
change, upgrade, and robotically service those instruments. It also provides a test bed for technology demonstration and technology maturation by providing long-term access to the space environment on the ISS.

NANORACKS-JAMSS-2LAGRANGE-1

 Скрытый текст:

Tomohiro Ichikawa, Lagrange Corp. (Tokyo, Japan)
Implementation Partner: NanoRacks

Spaceflight affects organisms in a wide range of ways, from a reduction in human bone density to changes in plant root growth. NanoRacks-JAMSS-2 Lagrange-1 helps students understand potential spaceflight-related changes by exposing plant seeds to microgravity, and then germinating and growing them on Earth. The plants are compared with specimens grown from seeds that remained on the ground. The investigation also connects students to the space program by sending their photographic likenesses and personal messages into orbit. This connection inspires the next generation of scientists and engineers who will work on international space programs.

NEUTRON CRYSTALLOGRAPHIC STUDIES OF HUMAN ACETYLCHOLINESTERASE FOR THE DESIGN OF ACCERERATED REACTIVATORS (ORNL-PCG)

 Скрытый текст:

Dr. Andrey Kovalevsky, Oak Ridge National Laboratory (Oak Ridge, TN)
Implementation Partner: CASIS

The investigative team is trying to improve our understanding of acetylcholinesterase, an enzyme essential for normal communication between nerve cells and between nerve and muscle cells. As a target of deadly neurotoxins produced by animals as venom or by man as nerve agents and pesticides, understanding the structure of acetylcholinesterase is critical to designing better antidotes to poisoning by chemicals that attack the nervous system. The Oak Ridge National Lab team plans to use the microgravity environment of space to grow large crystals of the enzyme that will be imaged back on Earth using a powerful imaging approach called neutron diffraction. Neutron diffraction yields very detailed structural information but requires much larger crystals than traditional x-ray diffraction imaging methods. The investigators hypothesize that structural images of space-grown crystals will bring us closer to more effective and less toxic antidotes for neurotoxins that bind and inhibit acetylcholinesterase.

STUDENT SPACEFLIGHTS EXPERIMENT PROGRAM - MISSION 10

 Скрытый текст:

Dr. Jeff Goldstein, National Center for Earth and Space Science Education (Washington, D.C.)

The Student Spaceflight Experiments Program (SSEP) provides one of the most exciting educational opportunities available: student-designed experiments to be flown on the International Space Station. The NanoRacks-National Center for Earth and Space Science Education-Odyssey (NanoRacks-NCESSE-Odyssey) investigation contains 24 student experiments, including microgravity studies of plant, algae and bacterial growth; polymers; development of multi-cellular organisms; chemical and physical processes; antibiotic efficacy; and allergic reactions. The program immerses students and teachers in real science, providing first-hand experience conducting scientific experiments and connecting them to the space program.

SYSTEMIC THERAPY OF NELL-1 FOR OSTEOPOROSIS (RODENT RESEARCH-5)

 Скрытый текст:

Dr. Chia Soo, University of California at Los Angeles (Los Angeles, CA)
Implementation Partner: NASA Ames Research Center and BioServe Space Technologies

Astronauts living in space for extended durations experience bone density loss, or osteoporosis. Currently, countermeasures include daily exercise designed to prevent bone loss from rapid bone density loss deterioration. However, in space and on Earth, therapies for osteoporosis cannot restore bone that is already lost. The Systemic Therapy of NELL-1 for Osteoporosis (Rodent Research-5) investigation tests a new drug on rodents that can both rebuild bone and block further bone loss, improving health for crew members in orbit and people on Earth. Dr. Soo's laboratory has been funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases within the National Institutes of Health. This experiment builds on those previous research investigations.

New NASA Mission to Study Mysterious Neutron Stars, Aid in Deep Space Navigation

A new NASA mission is headed for the International Space Station next month to observe one of the strangest observable objects in the universe.

Launching June 1, the Neutron Star Interior Composition Explorer (NICER) will be installed aboard the space station as the first mission dedicated to studying neutron stars, a type of collapsed star that is so dense scientists are unsure how matter behaves deep inside it.

A neutron star begins its life as a star between about seven and 20 times the mass of our sun. When this type of star runs out of fuel, it collapses under its own weight, crushing its core and triggering a supernova explosion. What remains is an ultra-dense sphere only about 12 miles (20 kilometers) across, the size of a city, but with up to twice the mass of our sun squeezed inside. On Earth, one teaspoon of neutron star matter would weigh a billion tons.

 Скрытый текст:

"If you took Mount Everest and squeezed it into something like a sugar cube, that's the kind of density we're talking about," said Keith Gendreau, the principal investigator for NICER at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Though we know neutron stars are small and extremely dense, there are still many aspects of these remnants of explosive deaths of other stars that we have yet to understand. NICER, a facility to be mounted on the outside of the International Space Station, seeks to find the answers to some of the questions still being asked about neutron stars. By capturing the arrival time and energy of the X-ray photons produced by pulsars emitted by neutron stars, NICER seeks to answer decades-old questions about extreme forms of matter and energy. Data fr om NICER will also be used in SEXTANT, an on-board demonstration of pulsar-based navigation.

Because neutron stars are so dense, scientists are uncertain how matter behaves in their interiors. In everyday experience, objects are composed of atoms. When neutron stars form, their atoms become crushed together and merge. As a result, the bulk of a neutron star is made up of tightly packed subatomic particles -- primarily neutrons, as well as protons and electrons, in various states. NICER measurements will help scientists better understand how matter behaves in this environment.

"As soon as you go below the surface of a neutron star, the pressures and densities rise extremely rapidly, and soon you're in an environment that you can't produce in any lab on Earth," said Columbia University research scientist Slavko Bogdanov, who leads the NICER light curve modeling group.

The only object known to be denser than a neutron star is its dark cousin, the black hole. A black hole forms when a star more than approximately 20 times the mass of our sun collapses. A black hole's powerful gravity establishes a barrier known as an event horizon, which prevents direct observation. So scientists turn to neutron stars to study matter at nature's most extreme observable limit.

"Neutron stars represent a natural density limit for stable matter that you can't exceed without becoming a black hole," said Goddard's Zaven Arzoumanian, NICER deputy principal investigator and science lead. "We don't know what happens to matter near this maximum density."

In order to study this limit, NICER will observe rapidly rotating neutron stars, also known as pulsars. These stars can rotate hundreds of times per second, faster than the blades of a household blender. Pulsars also possess enormously strong magnetic fields, trillions of times stronger than Earth's. The combination of fast rotation and strong magnetism accelerates particles to nearly the speed of light. Some of these particles follow the magnetic field to the surface, raining down on the magnetic poles and heating them until they form so-called hot spots that glow brightly in X-ray light.

"NICER is designed to see the X-ray emission from those hot spots," Arzoumanian said. "As the spots sweep toward us, we see more intensity as they move into our sightline and less as they move out, brightening and dimming hundreds of times each second."

A neutron star's gravity is so strong it warps space-time, the fabric of the cosmos, distorting our view of the star's surface and its sweeping hot spots. NICER will measure brightness changes related to these distortions as the star spins. This will allow scientists to determine the pulsar's radius, a key measurement needed to fully understand its interior structure.

"Once we have a measure of the mass and radius, we can tie those results directly into the nuclear physics of what goes on when you compress so much mass into such a small volume," Arzoumanian said.
 


In addition to understanding how neutron stars are put together, NICER's observations will also help scientists better understand the critical mass a star must achieve before it can turn into a black hole. This is particularly important in systems wh ere neutron stars orbit another star, allowing them to pull material off the companion star and gain more mass.

"The more neutron stars we observe at high masses, the higher the mass threshold becomes for a star turning into a black hole," said NICER science team member Alice Harding at Goddard. "Understanding what that critical mass is will help us determine how many black holes and neutron stars there are in the universe."

NICER will also provide scientists and technologists with a unique opportunity to make advances in deep space navigation. Its X-ray measurements will record the arrival times of pulses from each neutron star it observes, using the regular emissions of pulsars as ultra-precise cosmic clocks, rivaling the accuracy of atomic clocks such as those used inside GPS satellites. Built-in flight software -- developed for the Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) demonstration -- can see how the predicted arrival of X-ray pulses from a given neutron star changes as NICER moves in its orbit. The difference between expected and actual arrival times allows SEXTANT to determine NICER's orbit solely by observing pulsars.

Although spacecraft in Earth orbit use the same GPS system that helps drivers navigate on the ground, there's no equivalent system available for spacecraft traveling far beyond Earth.

"Unlike GPS satellites, which just orbit around Earth, pulsars are distributed across our galaxy," said Jason Mitchell, the SEXTANT project manager at Goddard. "So we can use them to form a GPS-like system that can support spacecraft navigation throughout the solar system, enabling deep-space exploration in the future."

Installation on the space station provides scientists and technologists with an opportunity to develop a multi-purpose mission on an established platform.

"With the NICER-SEXTANT mission, we have an excellent opportunity to use the International Space Station to demonstrate technology that will lead us into the outer solar system and beyond, and tell us about some of the most exciting objects in the sky," Gendreau said.

NICER is an Astrophysics Mission of Opportunity within NASA's Explorer program, which provides frequent flight opportunities for world-class scientific investigations from space utilizing innovative, streamlined and efficient management approaches within the heliophysics and astrophysics science areas. NASA's Space Technology Mission Directorate supports the SEXTANT component of the mission, demonstrating pulsar-based spacecraft navigation.

(Highlights: Week of May 22, 2017) - An unscheduled spacewalk on the International Space Station to replace a failed piece of critical command and control hardware delayed some planned investigations. However, right after the spacewalk ended, crew members picked right back up on the science timeline.

 Скрытый текст:

One of the investigations was in human research, as crew members drew blood for the Cardiac and Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) study. The Canadian Space Agency (CSA) investigation examines the changes in blood vessels and the heart while crew members are in space, and follows their recovery after returning to Earth.

As humans get older on Earth, arteries can stiffen, which causes an increase in blood pressure, elevating the risk of heart disease. Physicians have observed that crew members returning from the space station also have much stiffer arteries than before they went into space. The Vascular Echo investigation aims to give researchers a better understanding of the changes in the cardiovascular system, which may provide insight into potential countermeasures to maintain health in space and on Earth.

Ground teams commanded operations for the Combustion Integration Rack (CIR) on the space station in support of the Cool Flames Investigation. Some types of fuels initially burn very hot, then appear to go out -- but they continue burning at a much lower temperature with no visible flames. These phenomena are called cool flames. Understanding cool flame combustion could help scientists develop new engines and fuels that are more efficient and less harmful to the environment. The Cool Flames Investigation provides new insight into this phenomenon, as well as new data on fire safety in space.

Crew members also collected samples for the Biochemical Profile (Biochem Profile) investigation. The astronauts study themselves to learn how the human body reacts to long-duration spaceflight. Biochem Profile tests bodily fluid 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 to study the effects of spaceflight on the body. Establishing a chemical profile of the body's response to spaceflight will help scientists understand how different systems in the body interact in microgravity in different groups of people. Scientists can also test the effectiveness of possible countermeasures like exercise and nutrition and their effects on crew health during long-duration exploration missions.

An improved understanding of the biochemical effects of microgravity could help patients with limited mobility on Earth, such as those on bed rest. Understanding how various physiological systems respond and interact to changing gravity conditions could help physicians design different treatments or exercises for people with limited mobility.

Progress was made on other investigations, outreach activities, and facilities this week, including Cardio Ox, NanoRack CubeSat Deployer (NRCSD), Radi-N, Amateur Radio on the International Space Station (ISS Ham Radio (ARISS)), Light Microscopy Module Biophysics, Fine Motor Skills, Passive Thermal Flight Experiment, OsteoOmics, Body Measures, Dose Tracker, and Marrow.

For a year, @BigelowSpace's #BEAM expandable habitat has provided a new way of looking at living quarters in space: http://go.nasa.gov/2rqc8An 

https://www.nasa.gov/feature/first-year-of-beam-demo-offers-valuable-data-on-expandable-habitats

May 26, 2017

First Year of BEAM Demo Offers Valuable Data on Expandable Habitats

Halfway into its planned two-year demonstration attached to the International Space Station, the Bigelow Expandable Activity Module, or BEAM, is showing that soft materials can perform as well as rigid materials for habitation volumes in space. The BEAM was launched and attached to station through a partnership between NASA's Advanced Exploration Systems Division (AES) and Bigelow Aerospace, headquartered in North Las Vegas, Nevada.

NASA and Bigelow are primarily evaluating characteristics directly related to the module's ability to protect humans from the harsh space environment. Astronauts aboard station work with researchers on the ground to monitor the module's structural integrity, thermal stability, and resistance to space debris, radiation, and microbial growth.

 Скрытый текст:

Researchers at NASA's Langley Research Center in Hampton, Virginia, continually analyze data from internal sensors designed to monitor and locate external impacts by orbital debris, and, as expected, have recorded a few probable micrometeoroid debris impacts so far. BEAM has performed as designed in preventing debris penetration with multiple outer protective layers exceeding space station shielding requirements.


Astronauts aboard the space station 3-D printed a shield to cover one of the two Radiation Environment Monitors inside the BEAM. The shield, the white hemispherical shape at the center of the photograph, is shown above inside the BEAM module. In the coming months, the crew will print successively thicker shields to determine the shielding effectiveness at blocking radiation.

Over the next several months, NASA and Bigelow will focus on measuring radiation dosage inside the BEAM. Using two active Radiation Environment Monitors (REM) inside the module, researchers at NASA's Johnson Space Center in Houston are able to take real-time measurements of radiation levels. They have found that Galactic Cosmic Radiation (GCR) dose rates inside the BEAM are similar to other space station modules, and continue to analyze contributions to the daily dose from the Earth's trapped radiation belts to better understand the shielding properties of the module for application to long-term missions. The space station and the BEAM enjoy a significant amount of protection from Earth's magnetosphere. Future deep space missions will be far more exposed to energized radiation particles speeding through the solar system, so NASA is actively working on ways to mitigate the effects of radiation events.

In late April, NASA's radiation researchers at Johnson began a multi-month BEAM radiation experiment by installing a .04 inch (1.1 mm) thick shield onto one of the two REM sensors in BEAM. The station crew produced a hemispherical shield using the 3-D printer on the space station, and in the next few months this first shield will be replaced by two successively thicker shields, also 3-D printed, with thicknesses of about .13 inches (3.3mm) and .4 inches (10mm), respectively. The difference in measurements from the two REMs--one with a shield and one without--will help better resolve the energy spectra of the trapped radiation particles, particularly those coming from the South Atlantic Anomaly.

Space station crew members have entered the BEAM nine times since its expansion in May 2016. In addition to the REM shielding experiment activities, the crew has swapped out passive radiation badges called Radiation Area Monitors and they routinely collect microbial air and surface samples. These badges and samples are sent back to Earth for standard microbial and radiation analysis at Johnson.

The BEAM technology demonstration is helping NASA to advance and learn about expandable space habitat technology in low-Earth orbit for application toward future human exploration missions. The partnership between NASA and Bigelow supports NASA's objective to develop a deep space habitat for human missions beyond Earth orbit while fostering commercial capabilities for non-government applications.
