Experienced Trio Brings Station Crew up to Full Speed
Posted on August 1, 2017 at 11:34 pm by Mark Garcia.


Astronauts Paolo Nespoli and Randy Bresnik are at work in their new home in space where they will live until mid-December.

Expedition 52 is now up to full speed with six crew members. The latest trio from the United States, Italy and Russia arrived Friday afternoon beginning a 4-1/2 month mission in space.

Спойлер

The new crew is familiarizing itself with International Space Station systems and getting used to life 250 miles above Earth's surface. NASA astronaut Randy Bresnik is starting his second space mission and spent time on Tuesday replacing networking hardware in the Japanese Experiment Module.

Astronaut Paolo Nespoli of the European Space Agency is on his third spaceflight. Nespoli took part in the Sarcolab-3 study using the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module. The data collected for Sarcolab-3 will be used to assess microgravity's impact on muscle loss in astronauts, focusing specifically on the calf muscle in the leg.

Cosmonaut Sergey Ryazanskiy begins his second mission aboard the station as a flight engineer. He last visited the orbital complex in 2013 with his Expedition 37-38 crewmates. Ryazanskiy conducted routine maintenance across the station's Russian segment and assisted Nespoli during the Sarcolab-3 experiment session.

Sarcolab-3:

Спойлер

With assistance fr om a Russian operator, a USOS crewmember ingressed the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module and adjusted pads and constraints for the Sarcolab-3 ankle protocol. The operator then collected ultrasound images of the subject's right leg. Ground experts are evaluating anomalies that occurred during the investigation that prevented completion of the session. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) wh ere it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

This morning the crew took pictures of the Category 3 Typhoon Noru in the western Pacific. The Tropical Cyclone investigation is used to capture images of tropical cyclones and hurricanes that are rated at Category 3 or greater on the Saffir-Simpson scale. A pseudo-stereoscopic method is used to determine the altitudes of the cloud tops near the center (eye) of a cyclone by precisely tracking the apparent positions of cloud features with respect to the Earth and how those positions change over time as an observer (the ISS in this case) passes over the storm. The photographic images will be used to demonstrate that pseudo-spectroscopy can be used to measure the cloud altitudes to sufficient precision so that, when combined with other remote-sensing data, an accurate determination of the intensity of hurricane or cyclone can be made.

Common ailments that afflict people on Earth such as headaches also affect astronauts in space impacting their mission activities. Astronauts Paolo Nespoli and Randy Bresnik are jotting down their experiences this week to help doctors understand space headaches. Observations may reduce their effects and improve performance during spaceflight and on Earth.

NASA astronauts Jack Fischer and Peggy Whitson are studying a new drug for its potential to slow or reverse bone loss in space. They looked at bones in mice today to help determine the efficacy of the new drug. The lack of gravity causes osteoporosis-like symptoms weakening bones in space possibly impacting crews returning to Earth and experiencing gravity for the first time in months.

NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days fr om launch, they are confident the shoebox-sized satellite Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science. Dellingr will study how the ionosphere, a region in Earth's upper atmosphere, interacts with the Sun. Before launch, Dellingr is required to visit to the Magnetic Test Facility at NASA Goddard to test the spacecraft's magnetometers - key instruments for measuring the direction and strength of the magnetic fields that surround Earth. The spacecraft is scheduled to launch this August aboard a SpaceX Falcon 9 rocket to the International Space Station wh ere it will be deployed later into a low-Earth orbit.

NASA Set to Launch Dellingr; CubeSat Purposely Designed to Improve Reliability of Small Satellites

NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days fr om launch, they are confident Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science.

The shoebox-sized spacecraft is set to launch in August aboard a SpaceX Falcon 9 rocket to the International Space Station where it will be deployed later into a low-Earth orbit.

Спойлер

Dellingr is the brainchild of scientists with the Heliophysics Science Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and engineers with the center's Applied Engineering and Technology Directorate or AETD. Purposely designed to be more reliable than more widely used CubeSat platforms and relatively inexpensive, the six-unit, or 6U, Dellingr will demonstrate the vigor of its design, while gathering NASA-quality data about the sun's influence on Earth's upper atmosphere using a suite of miniaturized instruments and components [link to sidebar about instruments].

The team began developing Dellingr in 2014 in response to growing interest among NASA and other government scientists who wanted to use CubeSat platforms to carry out scientific investigations. Originally created by the California Polytechnic State University in 1999 for educational purposes, the university-class platform quickly gained popularity among universities interested in giving students hands-on experience building satellites.

In addition to their low cost, these tiny platforms intrigued scientists with their potential to fly swarms of these tiny platforms around Earth or other solar system bodies to gather simultaneous, multi-point observations — an observing technique not financially feasible with larger, more traditional spacecraft. Although they fulfilled their original academic purpose, scientists soon discovered that despite their huge potential for enabling new types of observations, the university-class CubeSat did not completely satisfy their needs.

"It was a reliability issue," said Michael Johnson, AETD's chief technologist, one of Dellingr's proponents. "While adequate, university-class CubeSats weren't consistent with what we wanted to do." As an example, Johnson cited the experience of Goddard scientist and Heliophysics Division Chief Technologist Nikolaos Paschalidis, whose success developing a miniaturized spectrometer was marred by CubeSat failures.


Chuck Clagett, Larry Kepko, and Michael Johnson were instrumental in developing the Dellingr 6U CubeSat shown here inside Goddard's magnetic calibration facility.

With his team, Paschalidis developed the world's smallest Ion-Neutral Mass Spectrometer for a 3U CubeSat mission that launched last year. However, soon after the spacecraft's launch, mission operators realized the spacecraft wasn't communicating properly, delaying the commissioning of important spacecraft functions. After about six months, Paschalidis finally confirmed his instrument's basic functionality, but the mission abruptly ended due to computer problems.

"The mission demonstrated the basic functionality of my instrument. However, the experience put a strong emphasis on the need for a robust bus and a complete mission-operations scenario," said Paschalidis, who is flying an improved version of his instrument on Dellingr.

Although the team believes it ultimately will succeed in its pathfinding mission, the road to launch wasn't always smooth.

Within months of starting Dellingr, the team discovered that building a reliable, 6U CubeSat was easier said than done. Although the team wanted to keep down costs largely by using commercially available subsystems, it discovered that these components didn't always play well together or work as advertised, requiring additional engineering and technician effort. These glitches extended schedules well past the one-year goal and drove up costs.

They also quickly learned that they would have to change the way they managed CubeSat missions to keep them affordable. "It's a new way of doing things," said Project Manager Chuck Clagett. "We were applying old ways to doing things to an emerging capability and it didn't work very well."

From the exercise, the team found a better balance between management and testing requirements and the critical need for more mission-enabling technologies, including CubeSat-specific software, Clagett said.

Just as important, the team learned the true cost of a CubeSat mission, said Goddard heliophysicist Eftyhia Zesta, who is the lead project investigator for the Dellingr magnetometers. The university-class CubeSat, developed with less rigorous design and system-engineering practices, isn't a realistic cost for highly reliable CubeSat missions, she said.

While Dellingr's developers await launch, they are heartened that NASA already is benefiting from their two-and-a-half-year effort to change the CubeSat paradigm. A recently sel ected CubeSat mission, the Plasma Enhancements in the Thermosphere Satellite, or petitSat, plans to use the second-generation Dellingr bus. The mission will study Earth's ionosphere, the atmospheric layer that can affect the transmission of communication signals.

"We know how to build satellite buses," said Larry Kepko, a Goddard heliophyicist who is now heading NASA Science Mission Directorate's small satellite initiative. "All of our satellite buses last forever. We wanted to do the same thing with CubeSats, but without burdening the platform and driving up costs and extending schedules. We endeavored to transition CubeSats fr om an educational to a science tool. I think we did that with Dellingr."

NASA-Developed Technologies Showcased on Dellingr's Debut Flight

Along for the ride on Dellingr's maiden journey is a suite of miniaturized NASA-developed technologies — one no larger than a fingernail — that in many cases already have proven their mettle in suborbital or space demonstrations, boosting confidence that they will perform as designed once in orbit.

Спойлер

Scientists and engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, built all the instruments, primarily with research-and-development program funding.

Ion-Neutral Mass Spectrometer

Спойлер

The Ion-Neutral Mass Spectrometer, developed by Goddard Principal Investigator Nikolaos Paschalidis and his team in less than a year, is a complicated instrument designed to sample the densities of neutral and ionized atom species in the atmosphere. During the Dellingr mission, it will measure the equatorial ionosphere, the atmospheric layer that affects the transmission of radio waves.

The team initially flew the instrument on a previous CubeSat mission. Although the instrument gathered "beautiful" ion-composition counts of hydrogen, helium, and oxygen, the CubeSat bus proved unreliable and the mission was aborted six months after launch, Paschalidis said.

"The immediate plan with Dellingr is to extensively prove the instrument's functionality. Assuming all goes well, we want to collect as much data as possible, calibrate for spacecraft attitude and location, analyze the data, and plot ion and neutral composition and densities as a function of orbit. This by itself is a unique data set," Paschalidis added.

Boom and No-Boom Magnetometer Systems

Спойлер

Two miniaturized magnetometer systems, developed by Goddard Principal Investigators Eftyhia Zesta and Todd Bonalsky, also were successfully demonstrated earlier this year aboard a sounding-rocket mission fr om Poker Flats, Alaska. On Dellingr, these instruments are expected to show a dramatic improvement in the accuracy and precision of miniaturized magnetometers by using a never-before-tried technique involving boom and no-boom systems.

Included in this observing technique is one thumbnail-sized magnetometer positioned at the end of a deployable boom and a couple sensors positioned inside Dellingr. The purpose of the internal sensors is measuring the magnetic fields, or "noise," generated by the spacecraft's torquers, solar panels, motors, and other hardware. Sophisticated algorithms that Zesta's team created then will analyze the external and internal magnetometer data to subtract spacecraft-generated noise from the actual science data.

"CubeSats, like any spacecraft, will be noisy; they are magnetically unclean," Zesta explained, adding that to avoid the problem in more traditional spacecraft, the magnetometer is placed at the end of a long boom. "Even with a one-meter (three foot) boom — unless there is a magnetic cleanliness program — you will need to use algorithms to get rid of bus noise. Algorithms are the only way to get scientific value from your data."

In comparison, the Dellingr the boom is only about 22-inches long and it is not magnetically clean, Zesta said. "We absolutely needed to develop noise-cancellation algorithms if we wanted to get any useful science data."

The Diminutive DANY

Спойлер

Deploying the magnetometer boom and UHF antenna is a miniaturized device called the Diminutive Assembly for Nanosatellite Deployables, or DANY. Created by technologist Luis Santos, it acts as a pin puller.


This is an engineering drawing of the Diminutive Assembly for Nanosatellite Deployables, or DANY, that stows antennas, solar panels, magnetometer booms, and even sunshades on CubeSats.

It operates much like a car-door latch. Affixed to the exterior of Dellingr, it holds the boom and antenna in place during launch and then, upon command, applies a current that activates a heating element, which weakens a plastic device holding the retaining pins. Once Dellingr reaches its intended obit, the satellite activates the heating element and the deployables will swing open to begin operations.

Goddard Fine Sun Sensor

Another technology making Dellingr's debut flight is the Goddard Fine Sun Sensor, or GFSS, designed specifically for CubeSats. The panel-mountable device will gather digital data orienting onboard instruments to the sun. As with the other Dellingr instruments, improvements are afoot. Principal Investigator Zachary Peterson is taking lessons learned from the Dellingr effort to improve GFSS's accuracy and lower its power consumption. Other flight opportunities are planned.

[свернуть]

Thermal-Control Technology

Спойлер

In addition to gathering or enabling the collection of scientific data, Dellingr will demonstrate technology. Principal Investigator Allison Evans is miniaturizing an older thermal-control technology that requires no electronics and consists of louvers that open or close, much like venetian blinds, depending on whether heat needs to be conserved or shed. During the flight, she wants to prove the louvers will operate as expected in a space environment.


Principal Investigator Allison Evans has repurposed an old thermal-control technology specifically for the CubeSat platform.

The device consists of front and back plates, flaps, and springs. The back plate is painted with a white, highly emissive paint and the front plate and flaps are made of aluminum, which aren't as emissive. The bimetallic springs do all the work. They are made of two different types of metal. Attached to the highly emissive back plate, the springs uncurl if one of the metals gets too hot, forcing the flaps to open. When the spring cools down, it reverts to its original shape and the flaps close.

For the Dellingr demonstration, Evans is flying just one flap/spring combination to help mature the technology in preparation for future missions wh ere the miniature thermal louvers would be an integrated part of the thermal design. "A mission with a temperature-sensitive instrument or a component that sheds significant amounts of heat only occasionally would be a good candidate for this technology," she said.

Dragon to be Packed with New Experiments for International Space Station

By Bob Granath
NASA's Kennedy Space Center, Florida

The International Space Station is a unique scientific platform enabling researchers from around the world to develop experiments that could not be performed on Earth. A line of unpiloted resupply spacecraft keeps this work going, supporting efforts to enable future human and robotic exploration of destinations well beyond low-Earth orbit.

The next mission to the space station will be the 12th commercial resupply services flight for SpaceX. Liftoff is targeted for Aug. 13 at approximately 12:56 p.m., from Launch Complex 39A at NASA's Kennedy Space Center in Florida. This underscores the center's role as a premier, multi-user spaceport as this will be the ninth SpaceX rocket to take off from the launch pad, all this year. Pad 39A's history includes 11 Apollo flights, the launch of the Skylab space station in 1973, and 82 space shuttle missions.

Спойлер

A SpaceX Falcon 9 rocket will boost a Dragon spacecraft filled with almost 6,000 pounds of supplies. The payloads include crucial materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 52 and 53.

About 10 minutes after launch, Dragon will reach its preliminary orbit and deploy its solar arrays. A carefully choreographed series of thruster firings are scheduled to allow the spacecraft to rendezvous with the space station. NASA astronaut Jack Fischer and European Space Agency astronaut Paolo Nespoli will grapple Dragon using the space station's robotic arm and install it on the station's Harmony module.

The station crew will unpack the Dragon and begin working with the experiments that include plant pillows containing seeds for NASA's Veggie plant growth system experiment. The plant pillows were prepared in Kennedy's Space Station Processing Facility.

Veggie, like most of the research taking place on the space station, is demonstrating how the research benefits life on Earth as it advances NASA's plans to send humans to Mars.

Astronauts Peggy Whitson and Jack Fischer work on station systems inside Japan's Kibo laboratory module.

From leg muscle scans to observing materials burning at high temperatures, the Expedition 52 crew continued researching what happens when you live in space. The space residents also upgraded electronics gear and installed new science racks.

Astronauts Randy Bresnik and Paolo Nespoli are barely a week into their 4-1/2 month long mission and are already exploring what space is doing to their bodies. The astronauts took ultrasound scans of their legs today to assess the changes their leg muscles and tendons are undergoing. The data will later be compared to the condition of their muscles before and after their spaceflight mission.

Jack Fischer of NASA installed new electronics gear in a science rack to speed up the communications rate at which data is uploaded and downloaded from the research facility. Station veteran Peggy Whitson swapped out samples exposed to high temperatures inside a specialized furnace. She later installed a pair of NanoRacks research platforms in the Kibo laboratory module. The commercial science devices will support upcoming experiments being delivered on the next SpaceX Dragon mission.

We are a Jack-of-all-trades on @Space_Station, some days science, some days repair or new improvements like today's Ethernet hub in the JEM

We have no weight in 0-g......but we can figure out our mass by riding along and measuring the damping rate of a highly calibrated spring!

Come si fa a pesare un astronauta in assenza di peso? Con il nostro dispositivo SLAMMD chiaramente! #VITAmission

How do you weigh an astronaut who's weightless? With the SLAMMD device of course! #VITAmission

Int-Ball Letter Vol. 2: Release on updated images of Kibo's internal drone "Int-Ball"

JAXA | 宇宙航空研究開発機構

Опубликовано: 2 авг. 2017 г.

JAXA has disclosed "Int-Ball Letter" Vol. 2 in which the latest video of the Kibo's internal drone on the International Space Station is presented. This time, we will introduce how Int-Ball checks its location and direction inside "Kibo". The Int-Ball project adopts an optical navigation technology called "Phenox" developed by the Artificial Intelligence Laboratory at the University of Tokyo, and body control using a 3-axis reaction wheel developed by the Research and Development Directorate of JAXA.

Advanced Plant Habitat Readied for Science
Posted on August 3, 2017 at 5:39 pm by Amanda Griffin.

Advanced Plant Habitat [/url]Flight Unit No. 1 that will be used for ground testing the agency's newest plant habitat arrived at Kennedy Space Center on July 17. Over the past couple of weeks, the unit has undergone numerous inspections and checkout procedures and is now undergoing an Experiment Verification Test. This test, started on July 27, will allow the ground team at Kennedy to run through the procedures of the future Plant Habitat 01 Mission, or PH-01, that will grow aboard the International Space Station later this year. Both the test and the actual mission will grow Arabidopsis seeds, which are small flowering plants related to cabbage and mustard.

The Advanced Plant Habitat was sent to the space station in two shipments on the Orbital ATK OA-7 and SpaceX CRS-11 resupply missions. Once it is set up, it will be a fully automated facility that will be used to conduct plant bioscience research. The Advanced Plant Habitat is an enclosed, closed-loop system with an environmentally controlled chamber. The habitat will use red, blue, green and broad-spectrum white LED lights and have 180 sensors to relay information back to the team at Kennedy. The habitat is scheduled to be activated aboard the orbiting laboratory this fall, with PH-01 beginning in late October.

Pulsing thrusters, cryogenic snow, docking port contact! Beautiful backdrop as we docked w/ @Space_Station last week. #TBT #SpaceVideosRock

Our crew Soyuz 51S docks with Space Station, July 28, 2017.
Docking two spaceships is essentially an orbital ballet culminating in a collision. In this case, very controlled, thanks to the excellent piloting skills of our Soyuz commander Sergey Ryazanskiy.
