Re: International Space Station (ISS / Alpha)

Headed to the station is "The biomining reactors will use bacteria to recover minerals and metals from rocks" World first as kits designed to extract metals from the Moon and Mars blast off for space station tests

biomining-reactors-bacteria-recover-minerals-metals-hg.jpg

They are to test how low gravity affects the ability of bacteria to extract materials such as iron, calcium and magnesium from space rocks. A total of Eighteen of the devices will undergo tests...

The 'BioRock' experiment is led by the University of Edinburgh, with the European Space Agency and the UK Space Agency, and is funded by the Science and Technology Facilities Council, part of UKRI.

https://www.gov.uk/government/organisat … ace-agency

It is the second UK-led experiment to take place on the International Space Station, after the 'Worms in Space' experiment launched in December 2018, and involves researchers from across Europe, including Belgium, Denmark, Germany, the Netherlands and Italy.

The experiment will also study how microbes grow and form layers - known as biofilms - on natural surfaces in space.

The findings could have numerous applications on Earth, including the recovery of metals from ores and the use of biofilms in industry and medicine.

waste extraction would also be something to review as well

Re: International Space Station (ISS / Alpha)

The talk about batteries is just what is happening on the space station.
Astronauts have kicked off the first of five spacewalks to replace old batteries at the International Space Station. Christina Koch and Andrew Morgan had to remove a pair of old batteries nickel-hydrogen batteries with more powerful lithium-ion.

Astronauts hustled through the first of five spacewalks to replace old batteries at the International Space Station on Sunday. Christina Koch and Andrew Morgan removed three old batteries and installed two new ones delivered just a week ago, getting a jump on future work.

Radiation Experiment, Cookie Oven and More Headed to Space Station on Cygnus Cargo Ship

SsKGToLbxXP5YQnAuMrjL6-650-80.jpg

Perched atop the rocket will be a Northrop Grumman Cygnus cargo spacecraft, and tucked inside will be approximately 8,200 lbs. (3,700 kilograms) of supplies and hardware. The craft will ferry supplies to support the crew on the space station as well as a variety of experiments and research equipment. These will support investigations in topics ranging from radiation mitigation to rover control to materials recycling.

So the first is rqadiation measurement for given protection level with easy of doning the protective gear..

One experiment aboard the Cygnus, the AstroRad Vest, aims to help NASA mitigate those damaging effects.

The AstroRad vest is a garment designed to help shield astronauts from radiation while traveling in space. It is made out of HDPE (high-density polyethylene) and will be tested by the crew currently onboard the space station. Although the vest is designed for use farther out into space, the space station is the perfect environment to test whether astronauts wearing the AstroRad garment will be comfortable and able to carry out their daily activities in space. Astronauts will record data on how easy the vest is to put on and how it fits, as well as the range of motion it allows.

Not your store bought easy bake oven for sure....so long as the choclate chip cookies are soft and chewy...

In testing this oven, astronauts will examine heat-transfer properties and the process of baking food in microgravity. The device has a specially designed toaster-like shape with a top temperature of 685 degrees Fahrenheit (363.3 degrees Celsius).

Re: International Space Station (ISS / Alpha)

A care package was sent for this problem..
NASA grant to study space station fungus

The center has been awarded a $750,000 grant by NASA to increase our understanding of the organisms and investigate ways to stop them.

mold-grows-international-space-station-exercise-clothes-hung-dry-hg.jpg

Every long-term mission has seen a growth of microbes where you don't want to see on the shuttle, Mir, and ISS.

The microbes are a type of fungus or bacteria called a biofilm. They represent a threat in space because they eat through the surfaces they grow on, a process called biodegredation. Biofilm formation also increases the risk of human illness. "It shows up behind control panels and has gotten into heat exchangers and pipe systems. On Mir, they once noticed a pretty bad stench. Looking for its source, they pulled off a panel and found a lot of mold. That was the smell, but it was also consuming plastic cabling in that area,".

That is a risk we do not need on mars...

Re: International Space Station (ISS / Alpha)

Here is something that will make it harder for man to remain in space in Zero gravity made some astronauts’ blood flow backwards

Spaceflight can halt and reverse blood flow in astronauts’ upper bodies of 11 Astronauts studied. Six of the astronauts experienced stagnant or reverse blood flow, one had a blood clot and another was found to have a potential partial blood clot. Instead, blood goes to the chest and head, causing astronauts to have puffy faces and bulging blood vessels in their necks. And appearance isn't the only ugly side effect. The lack of blood flowing to and from the brain can cause astronauts to feel dizzy and sometimes even faint …

In the space environment, the usual head-to-foot blood pressure and tissue fluid gradients that exist during the upright posture on Earth are removed. The subsequent shift in fluids from the lower to the upper portions of the body triggers adaptations within the cardiovascular system to accommodate the new pressure and fluid gradients. To counter this effect of gravity, veins in human legs have evolved valves that open and close to assist blood circulation back up to the heart.

Re: International Space Station (ISS / Alpha)

It is hard to believe that the International Space Station has continuously been home to astronauts for more than nineteen years. Solving the challenges of long duration space flight with 3D Printing

The eat, sleep, relax and exercise as well as perform science in LEO.

To make all of this possible requires sending more than 7,000 pounds of spare parts to the station annually. Another 29,000 pounds of spaceflight hardware spares are stored aboard the station and another 39,000 on the ground, ready to fly if needed.

The 3D Printing in Zero G investigation produced dozens of parts, which researchers analyzed and compared with those made on the ground. Analysis revealed that microgravity had no engineering-significant effects on the process, demonstrating that a 3D printer works normally in space and paving the way to new logistics systems for long duration missions.

Using recycled material for printer feedstock could save future long-duration exploration missions from having to carry a large supply of material for 3D printing. Recycling also could make use of material that otherwise would represent a nuisance or a trash disposal issue on these missions.

As a step toward that capability, the ReFabricator investigation demonstrates technology developed by Tethers Unlimited to recycle waste plastic materials, including previously printed items, into high quality 3D-printer filament. It began operations on the space station in February of 2019.

ISS upgrade update
Spacewalking astronauts wrap up battery improvements

NASA gradually has been replacing the space station's 48 aging, original-style nickel-hydrogen batteries with new and more powerful lithium-ion batteries. Only half as many of the new batteries are needed. So far, 18 new batteries have been installed over the past three years and 36 old ones removed.

Another batch of six new batteries will be launched to the orbiting lab this spring to complete the power upgrade. The old batteries, meanwhile, will be discarded in a supply ship.

These oversized, boxy batteries keep all the space station's systems running when the outpost is on the night side of Earth, drawing power from the sprawling solar wings. They're not easy to handle: Each is about a yard, or a meter, tall and wide, with a mass of about 400 pounds (180 kilograms.)

Re: International Space Station (ISS / Alpha)

We are getting ready to be able to cook in spoace and on mars surface with this work.

Experimental ISS oven allows astronauts to bake cookies in two hours

The results from the great spacey bake-off are finally in and have revealed that in order for astronauts to successfully bake a batch of cookies, they need to set their cooking timers to at least two hours.
The baking experiment, which took place on the International Space Station in late December and involved astronauts Luca Parmitano and Christina Koch, was carried out in an effort to determine whether it was at all possible to bake in space.
The five chocolate chip cookies used in the experiment have remained sealed in individual baking pouches at a lab in Houston, Texas, after being brought back to Earth on a SpaceX capsule in early January. However, erring on the side of caution, officials have steered clear of conducting any taste tests and instead started sifting through their baking data.
Most shocking of the findings was the difference in baking times between Earth and space. Compared to an average baking time of roughly 20 minutes on Earth, researchers found that astronauts weren't able to see any successful cookie results until the timer neared the two-hour mark.
"There's still a lot to look into to figure out really what's driving that difference, but definitely a cool result," Mary Murphy, a manager for Texas-based Nanoracks, said in a statement to the Associated Press. Nanoracks, alongside startup company Zero G Kitchen, was involved in the baking project by providing NASA with the specially-designed electric test oven. "Overall, I think it's a pretty awesome first experiment."
Data shows that the first of five cookie dough pieces was placed in the oven for a period of 25 minutes at a temperature of 300 degrees Fahrenheit and came out "seriously underbaked," according to AP. Although the temperatures were upped for the following two doughs, results didn't improve much.
A success wasn't radioed back to Earth by Parmitano until the fourth tester stayed in the prototype Zero G Oven oven for two hours. "So this time, I do see some browning. ... I can't tell you whether it's cooked all the way or not, but it certainly doesn't look like cookie dough anymore," the Italian astronaut reported.
The fifth tester, which was left in the oven for 130 minutes at a maximum temperature of 325 degrees Fahrenheit, proved a success as well. It was also noted in the findings that all but the first tester gave off a desirable cookie smell when removed from the oven.
Follow-up testing will be carried out in the near future in order to determine if the cookies are indeed safe for consumption. AP reported that additional experiments will be carried out by Nanoracks and Zero G Kitchen to develop more space kitchen appliances.

Re: International Space Station (ISS / Alpha)

Nasa has yet to change the station from an operations by governement to one that is commercial. Sure they are trying by setting up the commercial cargo and soon human space capability after a time I am sure will switch over to flying none partners to the stations. Since Bean is been quiet about adding more modules or creating that area that is open to private citizens that do not have a military governements backing. The tourist were rich and did do work onboard but for commercial to do more its time for space vacations and learning more about what else can be done as we orbit in LEO.

NASA selects first commercial destination module for International Space Station
axiom-space-iss-commercial-space-station-node-2-forward-port-module-hg.jpg

The Axiom Space module does loook simular to other vehicles that have visited and supported the station in the past.

The element will attach to the space station's Node 2 forward port to demonstrate its ability to provide products and services and begin the transition to a sustainable low-Earth orbit economy in which NASA is one of many customers. NASA and Axiom next will begin negotiations on the terms and price of a firm-fixed-price contract with a five-year base performance period and a two-year option. Developing commercial destinations in low-Earth orbit is one of five elements of NASA's plan to open the International Space Station to new commercial and marketing opportunities. The other elements of the five-point plan include efforts to make station and crew resources available for commercial use through a new commercial use and pricing policy; enable private astronaut missions to the station; seek out and pursue opportunities to stimulate long-term, sustainable demand for these services; and quantify NASA's long-term demand for activities in low-Earth orbit.
"Axiom's work to develop a commercial destination in space is a critical step for NASA to meet its long-term needs for astronaut training, scientific research, and technology demonstrations in low-Earth orbit,"
"We are transforming the way NASA works with industry to benefit the global economy and advance space exploration. It is a similar partnership that this year will return the capability of American astronauts to launch to the space station on American rockets from American soil."

Time to refill the cupboards.... Antares lofts Cygnus on 13th ISS resupply flight
Now the Northrop Grumman Antares 230 to ahead of an approximately two-day rendezvous with the ISS, where it will then be berthed to the ISS to resupply the three-person crew of Expedition 62.

The spacecraft is loaded with over 3,400kg of cargo, consisting of consumables and scientific experiments to be carried out on the ISS.

Included in the scientific hardware is a small microscope, which will act as a technology demonstrator for a new type of electron microscope, an experiment which will test the relationship between phages and their bacterial hosts in microgravity and space conditions and an experiment that will help us gain a better understanding of the bone mass loss astronauts undergo on orbit.
