Horizons science – perceiving time in space

European Space Agency, ESA

Опубликовано: 19 июл. 2018 г.

It often seems like the weekend is over in a heartbeat, while a working week can last forever. ESA astronaut Alexander Gerst explains how he is working with researchers to understand factors influencing time perception on board the International Space Station to help us up in space and on Earth.

As part of the Time experiment, Alexander wears a headset to block out any external visual cues and performs a series of computer prompted tasks designed to test his time perception. These include reproducing the length of a given event, estimating the amount of time elapsed, reacting to stimuli and judging the length of a minute. These results are compared to tests conducted on ground, as researchers gain a clearer picture of how and why perception is affected.

It's (Not) Alive: Chemical Gardens in Space

A classic laboratory investigation is being conducted aboard the International Space Station to better understand gravity's impact on nanotube growth in chemical gardens. Here on Earth, colorful crystal chemical gardens are often used to teach students about phenomena like hydrothermal vents and chemical reactions. Although completely inorganic, these gardens resemble plants and are influenced in their development by the pull of gravity.

This investigation examines how microgravity might change growth patterns of these gardens.

Chemical gardens form when dissolvable metal salts are placed in an aqueous solution containing anions such as silicate, borate, phosphate, or carbonate. The most common solution used is sodium silicate, and when the two are introduced, precipitation structures can form within minutes. The result is a vine-like array of buds, limbs and tubes. Gardens can range in color depending on the chemicals used.


The above garden developed by adding cobalt, copper, iron, nickel, and zinc salts to a sodium silicate solution.

Delivered to the space station aboard SpaceX CRS-15, astronauts will process the samples for an investigation called Understanding Growth Morphologies in Chemical Gardens (Chemical Gardens) and grow them throughout Expedition 56 before returning the results to Earth for full study.

"We expect macroscopic and microscopic morphology changes," said Chemical Gardens' researcher and doctoral candidate Alexander Blanchard. "While on-Earth growth tends to be upward, we expect growth in random directions and a spherical shape in space at the macroscopic level."

Once the investigation's in-orbit phase is complete, samples will be returned to Marshall Space Flight Center, home base for the Chemical Gardens research team. Here, samples will be photographed extensively at the macroscopic and microscopic level.

"We will use a scanning electron microscope to look at morphology," said Chemical Gardens' co-investigator Ellen Rabenberg. "This lets us see at up to 5,000x or 10,000x magnification as opposed to the 50x or 100x you would see from optical microscopes." This imagery will allow every aspect of the gardens to be studied in great detail.

While this is not the first set of chemical gardens grown in space, the proposed experiments could expand our knowledge of this phenomena. 


Although completely inorganic, these gardens resemble plants and are influenced in their development by the pull of gravity.

"Being able to isolate pressure in the absence of buoyancy could allow us to better understand their growth and tailor them to specific applications and give us further insight into reaction-diffusion chemical systems and self-organization," said Blanchard.

Applications from this investigation could include a better understanding of cement science and corrosion, potential improvements for tube walls for catalytic applications, and improvements to biomaterial devices used for scaffolding and compatibility with living cells and tissues. In space, chemical gardens could be grown to create similar scaffolds and thorough study of microgravity's effect will allow for better control of the gardens' growth.

Today's Research Explores How Space Impacts Life and Physics

Mark Garcia
Posted Jul 19, 2018 at 4:42 pm


NASA astronauts Ricky Arnold and Drew Feustel are at work inside the U.S. Destiny laboratory module.

The six orbital residents living aboard the International Space Station worked on a broad array of advanced space experiments and research gear today. Today's life science research included exploring fertility, extracting DNA from microbes and studying how the heart adapts to living in space. The crew also researched space physics observing magnetic fields, exploring the micro-properties of cement and detecting neutron radiation.

Спойлер

The Micro-11 experiment seeks to determine if human reproduction is possible in outer space. The study utilizes a microscope and the Microgravity Science Glovebox and observes sperm samples to determine the viability of fertility beyond Earth. DNA is being extracted from microbe samples swabbed off surfaces inside the space station. The DNA will be sequenced on Earth to help scientists understand how life adapts to microgravity. An ongoing Russian study is researching how a crew member's heart and circulatory system adjusts to a long-term space mission.

A European astrophysics investigation is looking at how Earth's magnetic field interacts with conductors. The study may provide insights for electrical engineers them design better space systems. Cement research is important in space and the crew has been exploring its microstructure possibly impacting the construction of future space habitats. Finally, radiation detectors have been deployed inside the orbital lab for a Canadian experiment to understand how neutrons affect astronauts.

ISS Daily Summary Report – 7/17/2018

Electro-static Levitation Furnace (ELF):

Спойлер

Today the crew exchanged sample cartridges to prepare for ground-commanded operations in the ELF. The ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the electrostatic levitation method. With this facility, thermophysical properties of high temperature melts can be measured and solidification fr om deeply undercooled melts can be achieved.

Rodent Research-7 (RR-7):

Спойлер

Today the crew calibrated the Mass Measurement Device that was installed yesterday in the Microgravity Science Glovebox (MSG). The mice were placed individually into the Container, loaded into the MMD and had three measurements performed on them. Fecal pellets and Food Bar swabs were collected and placed into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). Half of the mice went through this process today and the other half will go through it tomorrow. The RR-7 investigation examines how the space environment affects the community of microorganisms in the gastrointestinal tract of mice (also known as the microbiota). It also looks at microgravity's effects on multiple physiological systems known to be affected by the microbiota, including the gastrointestinal, immune, metabolic, circadian, and sleep systems. These studies should help explain mechanisms underlying interactions between these systems and the role of the microbiota in these interactions

Space Algae:

Спойлер

The crew agitated and installed an additional six Space Algae culture bags in the Veggie facility today. The Space Algae investigation explores the genetic basis for productivity of algae cultivated in space and whether this requires genetic adaptations or not. Algae may perceive microgravity as an abiotic stress, which can trigger production of high value compounds. Investigators plan whole genome sequencing of the space-grown algal populations to identify genes related to growth in spaceflight and testing of algal composition for production of high value compounds.

Aerosol Samplers:

Спойлер

Today the crew retrieved the Active Aerosol Samplers (AASs) that were deployed yesterday in Node 1 and Node 3. They connected them to the sample chargers and then redeployed them for a second run. The battery-powered AASs actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing the sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the cold side of the channel, wh ere an electron microscope (EM) grid is held in place by a tiny magnet. When returned to Earth, these grids are easily removed and placed directly in an EM for analysis.

Weather-monitoring and tech demo CubeSats deployed in orbit

Fifteen CubeSats owned by NASA, Spire Global, and U.S. research institutions launched aboard a Northrop Grumman Cygnus cargo ship in May have been released into orbit, beginning missions to demonstrate miniaturized, low-cost Earth science instruments and join a commercial network of weather-monitoring nanosatellites.

Nine of the satellites were released July 13 from a NanoRacks deployer outside the International Space Station, and six more sprung out of a NanoRacks carrier module mounted to the exterior of the Cygnus supply ship July 15, hours after the automated freighter departed the station.

The nine CubeSats released from the space station were delivered inside the Cygnus spacecraft's pressurized cargo module May 24, three days after launching from Wallops Island, Virginia. Astronauts transferred the nanosatellites, which ranged in size from a Rubik's Cube to a briefcase, inside a separation mechanism through an airlock in the station's Kibo lab module, wh ere a robotic arm picked up the deployer to release the CubeSats.

Seven of the CubeSats came from NASA and other U.S. universities, and two were developed by start-up companies.

One of the CubeSats, named RainCube, carries a miniaturized radar developed by NASA's Jet Propulsion Laboratory. The Ka-band radar, designed to measure rainfall and other precipitation on Earth, is the first such instrument to fit inside a CubeSat, according to Eva Peral, RainCube's principal investigator at JPL.

"CubeSats have been around for a long time, so what is the challenge about putting a radar in a CubeSat? Radars are notorious for being very large, very power-hungry instruments," Peral said before RainCube's launch May 21. "A group of JPL engineers developed a new architecture for radars, and we were able to reduce the size, mass and power consumption of the radar by about an order of magnitude, about a factor of 10."

RainCube was programmed to deploy a dish-shaped 1.6-foot (50-centimeter) radar antenna after its release from the space station. The roughly 26-pound (12-kilogram) spacecraft is designed for a two-month primary mission to test out the radar.

Peral said NASA's CloudSat satellite, which launched in 2006, carries a similar radar to RainCube. But the instrument aboard CloudSat is around 80 times the volume of the radar on RainCube.

"It's a significant advancement in technology," Peral said.

If the radar and antenna function as intended, RainCube could pave the way for future CubeSats to collect global precipitation data with greater frequency and at lower cost than existing satellite missions. The antenna technology also has applications in commercial communications networks.

"With RainCube, we expect that we could send a constellation of these little CubeSats (into orbit), and then we could measure very frequent observations of precipitation," Peral said.

Another CubeSat, named TEMPEST-D, deployed from the space station July 13 to begin its own technology demonstration mission.

Developed in partnership between JPL, Colorado State University and Blue Canyon Technologies, TEMPEST-D stands for the Temporal Experiment for Storms and Tropical Systems – Demonstration. The briefcase-sized CubeSat hosts a five-channel millimeter-wave radiometer that could be used by a fleet of future nanosatellites to scan developing tropical cyclones help scientists learn how they intensify and change.

"With a train-like constellation of TEMPEST-like CubeSats, we'd be able to take time samples every five to 10 minutes to see how a storm develops," said Steven Reising, TEMPEST-D's principal investigator at Colorado State University.

The CubeRRT nanosatellite was also released into orbit July 13 to begin a year-long mission testing a new processor that could help future Earth observation and climate research spacecraft obtain better data.

The processor on the CubeRRT tech demo CubeSat is designed to eliminate the effects of man-made radio emissions that reduce the precision of microwave radiometers on-board larger Earth science satellites.

Radio signals from wireless communications and radar operations on Earth can reach receivers on satellites, masking the planet's natural microwave emissions in the same frequency bands, which are useful for sensors looking at water vapor in the atmosphere, precipitation, sea surface temperatures and ice coverage, according to Joel Johnson, CubeRRT's principal investigator at Ohio State University.

"This is a problem for microwave radiometers trying to observe Earth, and as demand for the spectrum keeps getting higher and higher, it's harder and harder to keep doing these important scientific measurements," Johnson said.

"CubeRRT is all about a new kind of processor to attach to a microwave radiometer so that it can still continue to measure the natural thermal emissions, even in the presence of other signals that are coming from Earth that are man-made," Johnson said.

HaloSat was another CubeSat deployed from the space station July 13.

Developed at the University of Iowa in partnership with NASA, HaloSat is designed to detect X-ray gas emissions around the Milky Way galaxy. Scientists hope HaloSat's measurements will help determine the shape and mass of a halo of hot gas surrounding the galaxy.

The results could help astrophysicists in their search for "missing" matter — material that has escaped detection since the aftermath of the Big Bang produced relic light known as the cosmic microwave background. Since the birth of the universe 13.8 billion years ago, matter has coalesced to form structures such as gas and dust clouds, galaxies, stars and planets.

Cosmologists say the universe contains just 5 percent normal matter — the stuff you can see and touch — while 25 percent of the universe is made up of dark matter, and 70 percent is dark energy, a mysterious force accelerating the universe's expansion.

But scientists have accounted for only about half of the normal matter that should be in the universe. Researchers believe the undetected matter could be contained in hot gas clouds between galaxies, or in halos surrounding galaxies like our own Milky Way.

HaloSat's measurements could help scientists determine whether galactic halos of hot gas could harbor the missing matter.

The first privately-developed nanosatellite for Analytical Space, a startup based in Massachusetts, was also deployed from the space station July 13.

Named Radix, the CubeSat is a proof-of-concept tech demo mission for Analytical Space, which is developing a constellation of nanosatellites that could create a commercial data relay network. The CubeSats proposed by Analytical Space would receive data from other satellites via radio signals, then process the data and transmit it to Earth with a laser transmitter, which can beam information at higher data rates than feasible with conventional radios.

The approach would allow remote sensing craft, orbiting surveillance platforms, and other satellites using existing technology to take advantage of higher-speed laser communications, according to Analytical Space, which is backed by The Engine, a venture capital fund founded by MIT and other private investment firms.

Engineers will use Radix for beta-testing of the data relay concept. Analytical Space says it has lined up partners to use their satellites to communicate in orbit with Radix, which will then downlink the data to Earth through high-speed radio and laser terminals.

Four other CubeSats were released from the space station July 13:

• EQUiSat, a 1U CubeSat developed by Brown University with NASA support as an educational outreach mission, with a secondary objective of demonstrating a new type of battery in space.
• MemSat, a 1U CubeSat developed at Rowan University in partnership with NASA, will test a memristor device that could be flown on future satellites to make them more energy efficient and more resilient to power failures.
• RadSat-g, a 3U CubeSat developed at Montana State University in partnership with NASA, will test a new radiation tolerant computer system.
• EnduroSat One, a 1U CubeSat developed in Bulgaria, carries an amateur radio payload.

Awesome week of science on @Space_Station last week. My personal highlight was isolating, amplifying, then decoding bacterial DNA. Lots of potential uses in space & remote communities on Earth.

Рано или поздно еда из стандартного рациона приедается.

Для того, чтобы разнообразить рацион, один раз в месяц мы получаем так называемые бонусные контейнеры с дополнительным набором продуктов промышленного производства.
