SpaceX's CRS-21: A Mission of Many Firsts

Danielle Sempsrott
Posted Dec 4, 2020 at 1:02 pm



While this launch marks the first under SpaceX's second Commercial Resupply Services contract with NASA, the mission also brings many other firsts to the table:

• CRS-21 will be the first to splash down in the Atlantic Ocean upon the uncrewed cargo Dragon's return to Earth
• First time the crew access arm was used to load a cargo resupply mission
• The first time there will be two Dragon spacecraft docked to the International Space Station (uncrewed cargo Dragon and the Crew-1 Dragon)
• First automated docking to station for a SpaceX cargo resupply mission
• First flight of SpaceX's upgraded cargo version of Dragon, which can carry more science payloads to and from the space station

With the upgraded Dragon spacecraft comes double the capacity for powered lockers that preserve science and research samples during transport to or from Earth. The CRS-1 Dragon had six lockers available, whereas the upgraded version of Dragon has 12.

The upgraded Dragon also provides the capability for science payloads to remain in the spacecraft for the full duration of the mission. While the spacecraft is docked at the orbiting laboratory during CRS-21, four powered payloads will reside in Dragon.

NASA Science, New Airlock Heads to Space Station on SpaceX Cargo Spacecraft


SpaceX launched its 21st commercial resupply mission to the International Space Station at 11:17 a.m. EST Dec. 6, 2020, from Launch Pad 39A at NASA's Kennedy Space Center in Florida.

The latest SpaceX Dragon resupply spacecraft is on its way to the International Space Station with more than 6,400 pounds of science investigations, a new airlock, and other cargo after launching at 11:17 a.m. EST Sunday from NASA's Kennedy Space Center in Florida.

The spacecraft launched on a Falcon 9 rocket from Launch Pad 39A at Kennedy and is scheduled to arrive at the space station around 1:30 p.m. Monday, Dec. 7, performing the first autonomous docking for SpaceX and remaining at the station for about a month. Coverage of arrival will begin at 11:30 a.m. on NASA Television and the agency's website.

This 21st contracted resupply mission for SpaceX is the first flight of an upgraded Dragon design, similar to that of the Crew Dragon used to transport astronauts to and from the station. The upgraded spacecraft has double the capacity for powered lockers, with 12, which preserve science and research samples during transport to and from Earth. Science payloads now also can remain in the upgraded Dragon through the duration of the mission as an extension to the station's lab space. Four powered payloads will reside in Dragon during this docked mission.

Among the scientific investigations Dragon is delivering to the space station are:

Microbial meteorite miners

A mixture of meteorite samples and microbes are headed to the space station. Certain microbes form layers on the surface of rock that can release metals and minerals, a process known as biomining. A previous investigation from ESA (European Space Agency), BioRock, examined how microgravity affects the processes involved in biomining. ESA follows up on that work with BioAsteroid, which examines biofilm formation and biomining of asteroid or meteorite material in microgravity. Researchers are seeking a better understanding of the basic physical processes that control these mixtures, such as gravity, convection, and mixing. Microbe-rock interactions have many potential uses in space exploration and off-Earth construction. Microbes could break down rocks into soils for plant growth, for example, or extract elements useful for life support systems and production of medicines.

Examining changes in hearts using tissue chips

Microgravity causes changes in the workload and shape of the human heart, and it's still unknown whether these changes could become permanent if a person lives in space more than a year. Cardinal Heart studies how changes in gravity affect the heart at the cellular and tissue level. The investigation uses 3D-engineered heart tissues, a type of tissue chip. Results could provide a new understanding of heart problems in patients on Earth, help identify new treatments, and support the development of screening measures to predict cardiovascular risk before spaceflight.

Counting white blood cells in space

HemoCue tests the ability of a commercially available device to provide quick and accurate counts of total and differentiated white blood cells in microgravity. Doctors commonly use the total number of white blood cells and five different types of white blood cells to diagnose illnesses and monitor a variety of heath conditions. Verification of an autonomous blood analysis capability on the space station could enhance health care on Earth and is an important step toward meeting the health care needs of crew members on future missions.

Building with brazing

SUBSA-BRAINS examines differences in capillary flow, interface reactions, and bubble formation during the solidification of brazing alloys in microgravity. Brazing is a type of soldering used to bond materials, such as an aluminum alloy to aluminum or aluminum alloy to ceramics, at high temperatures. The technology could serve as a tool for in-space construction of human habitats and vehicles on future space missions, as well as for repairing damage caused by micrometeoroids or space debris.

A new and improved door to space

Launching in the trunk of the Dragon capsule, the Nanoracks Bishop Airlock is a commercial platform that can support a range of scientific work on the space station. Its capabilities include deployment of free-flying payloads such as CubeSats and externally mounted payloads, housing small external payloads, jettisoning trash, and recovering external Orbital Replacement Units. ORUs are modular components of the station that can be replaced when needed, such as pumps and other hardware. Roughly five times larger than the airlock on the Japanese Experiment Module already in use on the station, the Bishop Airlock allows robotic movement of more and larger packages to the exterior of the space station, including hardware to support spacewalks. It also provides capabilities such as power and ethernet required for internal and external payloads.

Your brain on microgravity

The Effect of Microgravity on Human Brain Organoids study observes the response of brain organoids to microgravity. Small living masses of cells that interact and grow, organoids can survive for months, providing a model for understanding how cells and tissues adapt to environmental changes. Organoids grown from neurons or nerve cells exhibit normal processes such as responding to stimuli and stress. Therefore, organoids can be used to look at how microgravity affects survival, metabolism, and features of brain cells, including rudimentary cognitive function.

These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars through NASA's Artemis program.

New Dragon Spaceship Arriving at Station Today

Mark Garcia
Posted Dec 7, 2020 at 10:02 am


The upgraded SpaceX Dragon resupply ship lifts off atop the Falcon 9 rocket on Dec. 6 from Kennedy Space Center in Florida.

SpaceX Dragon is on track to arrive at the International Space Station, with an expected docking of the cargo spacecraft around 1:30 p.m. EST. NASA Television coverage will begin at 11:30 a.m. Watch live at http://www.nasa.gov/live.

When it arrives to the space station, Dragon will automatically dock to the space-facing side (zenith) of the station's Harmony module with NASA astronauts Kate Rubins and Victor Glover monitoring operations. Dragon lifted off Sunday, Dec. 6 atop a SpaceX Falcon 9 rocket from Space Launch Complex 39A at NASA's Kennedy Space Center in Florida. The cargo spacecraft with more than 6,400 pounds of research, crew supplies and hardware will support dozens of investigations aboard the orbiting laboratory. It will be the first time a cargo Dragon autonomously docks to the station and will join the Dragon Resilience that brought the Crew-1 astronauts to orbit as the second Dragon spacecraft parked at the space station.

ISS Daily Summary Report – 12/03/2020

Fiber Optic Production (FOP):

Спойлер

The crew reviewed procedures and performed the setup of hardware in the Microgravity Science Glovebox. The Fiber Optic Production investigation creates optical fibers with high commercial value aboard the ISS using a blend of zirconium, barium, lanthanum, sodium, and aluminum called ZBLAN. It operates in the Microgravity Science Glovebox (MSG). Extensive theoretical studies along with a limited number of experimental studies suggest that ZBLAN optical fibers produced in microgravity should exhibit far superior qualities to those produced on Earth. The resulting optical fiber from Fiber Optic Production is expected to help verify these studies and guide further engineering efforts to manufacture high value optical fiber in large volume aboard the ISS.

Cell Biology Experiment Facility-L (CBEF-L):

Спойлер

The crew retrieved the CBEF Humidifier-2 from CBEF Incubator Unit (IU) Micro-G and refilled it with water and then re-installed the unit. CBEF-L is a Japan Aerospace Exploration Agency (JAXA) new subrack facility, which is an upgraded facility of the original Cell Biology Experiment Facility (CBEF) currently aboard the International Space Station (ISS). CBEF-L provides new capabilities with additional new resources such as Full High Definition video interface, Ethernet, 24 VDC power supply, and a larger diameter centrifugal test environment. By using the original CBEF and CBEF-L as one facility for the same experiment, the payload user is provided with an upgraded experimental environment that can handle the processing of more experimental samples for a wider array of experiments.

Materials Science Laboratory (MSL) Sample Cartridge Assemblies (SCA) Batch-2b #13:

Спойлер

The crew removed the MSL Furnace Calibration Cartridge and installed the new MSL Solidification and Quenching Furnace (SQF) Sample Cartridge in preparation of the next sample run. The Batch-2b of the MSL SCA Batch 2b-ESA serves two projects investigating how different phases organize in a structure when metallic alloys are solidified. The project Metastable Solidification of Composites (METCOMP) studies the phase formed by the reaction of the remaining liquid phase with an already formed solid, to form a second solid phase on cooling. For this purpose, Bronze (Copper-Tin Alloys) of different compositions will be processed. The other project, Solidification along a Eutectic path in Ternary Alloys (SETA), looks at how two phases that form together organize into lamellar, or fibre, structures when cooling Aluminium (Copper-Silver Alloys). Both projects will provide benchmark samples that will enable to test numerical models that aim to predict these structures.

Plant Habitat-02:

Спойлер

The crew installed the Science Carrier #1 into the Plant Habitat Facility and performed a water refill. Assessment of Nutritional Value and Growth Parameters of Space-grown Plants (Plant Habitat-02) cultivates radishes as a model plant that is nutritious and edible, has a short cultivation time, and is genetically similar to Arabidopsis, a plant frequently studied in microgravity. Developing the capability for food production in space requires understanding cultivation conditions such as intensity and spectral composition of light and the effects of the culture medium or soil. This research could help optimize plant growth in the unique environment of space, as well as evaluation of nutrition and taste of the plants.

Burning Rate Emulator (BRE):

Спойлер

The crew performed O₂/N₂ gas bottle changes in preparation for upcoming BRE runs. The BRE investigation is conducted in the Combustion Integrated Rack (CIR) on the ISS, as part of the Advanced Combustion via Microgravity Experiments (ACME) project. In this fire safety study, the flammability of solid and liquid materials is simulated by burning gaseous fuels under key conditions corresponding to the solid and liquid materials. This technique has been demonstrated for a wide variety of materials in normal-gravity and could provide an efficient way to screen and select fire-resistant materials for use in spacecraft, if the technique is similarly effective in microgravity.

Extravehicular Activity (EVA) Preparations:

Спойлер

The crew completed several activities in preparation for potential December EVAs. The crew inspected the Retractable Equipment Tether (RET) set, other hardware with integrated RETs, safety tethers, waist tethers, and D-ring extenders for suitability for use on upcoming US EVAs. Additionally, the crew performed a Contingency Water Container – Iodinated (CWC-I) degassing procedure.

Развеиваем миф о тюбиках... или чем питаются космонавты? Если открыть любой наш контейнер, то можно обнаружить 2 типа упаковки – пакеты с сублимированными продуктами и консервы.

Как я уже говорил ранее, рационы питания одинаковые для всех и рассчитаны на 16 суток.
