Make the ISS Bathroom Less Disgusting

Space Poop

Space may be devoid of life, but us Earthlings are working hard to change that, especially when it comes to the bacteria growing in the International Space Station’s bathroom.

The ISS’s bathroom isn’t the cleanest place in the universe, which is a problem given that space travel can weaken a person’s immune system — and that antibiotic-resistant bacteria have already been found on board.

“Spaceflight can turn harmless bacteria into potential pathogens,” said Elisabeth Grohmann, a microbiologist at Beuth University of Applied Sciences Berlin, in a press release. “Just as stress hormones leave astronauts vulnerable to infection, the bacteria they carry become hardier — developing thick protective coatings and resistance to antibiotics — and more vigorous, multiplying and metabolizing faster.”

No-Stick Surface

To help keep any astronauts who may have forgotten to wash their hands safe, Grohmann and her team developed a new, antimicrobial coating made of silver and ruthenium that they call AGXX, according to research published Wednesday in the journal Frontiers in Microbiology.

To test it out, the scientists put an AGXX coating on the ISS’s bathroom door. After six months, they didn’t find a bacterial cell on the surface. Some bacteria emerged after a year, but the AGXX coating still hosted 80 percent less bacteria than an uncoated steel door, according to the research.

Get the Elbow Grease

In the same press release, Grohmann blamed the bacterial growth on dust and other things that could have gotten in the way of the AGXX, adding that none of the bacteria that did survive was particularly dangerous.

“With prolonged exposure time a few bacteria escaped the antimicrobial action,” Grohmann said. “The antimicrobial test-materials are static surfaces, where dead cells, dust particles and cell debris can accumulate over time and interfere with the direct contact between the antimicrobial surface and the bacteria.”

It may not be perfect over long periods of time, but anything that keeps astronauts’ space poop where it belongs is a step in the right direction as NASA and other organizations figure out how to travel deeper into space over longer periods of time.

Von Braun Station: the first space hotel would be ready by 2025

Inspired by the concepts of a Nazi rocket scientist, Wernher von Braun, this station-hotel Von Braun Station will have its own gravity, kitchen, bars and interiors made with natural materials, and will be able to accommodate up to 400 people.

Von Braun Station

“The station could receive the first tourists in a few years,” said Tim Alatorre, senior architect of the Gateway Foundation , the company responsible for the station’s design.

“The goal of the Gateway Foundation is that in 2025 Von Braun already works and 100 tourists visit it per week,” he said.

According to the designer, the station, which will have the shape of a huge 190-meter diameter wheel, will turn constantly, creating an artificial gravitation comparable to that of the Moon and making the stay in it much more comfortable than in the ISS, where it is not possible to have a sense of direction.

The concept was taken from nothing less than Wernher von Braun, hence its name. This was a leading Nazi scientist who developed the V2 rocket. After World War II, NASA welcomed him to design, among other things, the Saturn V rocket that would take the human being to the Moon.

How will it be built?

The hotel station will be built by using automated systems, such as drones and robots, while in orbit. It will also use GSAL, special space construction machinery developed by Orbital Construction.

Once completed, some modules will be rented as individual residences, while others will be offered to different governments for scientific purposes. In total, the Gateway Foundation expects the population of the Von Braun wheel to be about 400 people.

In space … at home

Apart from rooms, the hotel part of the wheel will feature many of the things that are seen on cruises, such as restaurants, bars, music concerts, film screenings and educational seminars. Also, the interiors will have nothing to do with the sterility of the space stations of science fiction films.

«As humans, we are innately connected with natural materials and colors. […] The use of fabrics, lighting and warm-colored paints and textured materials help us connect and feel at home, ”said Alatorre, although he admitted that heavy materials, such as wood and stone, will be replaced by“ substitutes for light and easy to clean natural materials ».

The architect said that the project, which presupposes the creation of even larger space hotels, tries to put an end to the current high prices of orbital tourism, making it accessible to broad social sectors and facilitating extraterrestrial exploration.

” Gateway Foundation aims to make space travel open to everyone and this and the company’s next project will be true cities in space that will be ports of call for those who come and go from the Moon and Mars,” he concluded. .

Ariana Grande Responds to NASA Interns Remixing Her Song

It’s no secret that Ariana Grande is a fan of space and, by extension, the folks over at NASA. And it turns out that the love is reciprocal, seeing as how a group of interns at NASA’s Johnson Space Center have just given her song “NASA” the remix treatment.

An “educational parody” of Grande’s track, the interns created an accompanying video “in order to inform the public about the amazing work going on at NASA and thee Johnson Space Center,” per its description.

Even cooler? The specific project the interns that inspired the interns is NASA’s forthcoming Artemis missions, which aims to send the first woman to the moon by 2024.

Given all of this, Grande was obviously over-the-moon about the parody. No pun intended.

“Oh my. this is so pure and special and insane,” she tweeted in response. “hi everyone over there that is doing such incredible work ! thank u for taking the time to make this ! my heart is ….. bursting.”

Watch the entire remix video for yourself, below.

Another Interstellar Comet Has Arrived

“Based on the available observations, the orbit solution for this object has converged to the hyperbolic elements shown below, which would indicate an interstellar origin. A number of other orbit computers have reached similar conclusions, initially D. Farnocchia (JPL), W. Gray, and D. Tholen (UoH).”

Remember ‘Oumuamua, the first interstellar object ever discovered in our solar system? You won’t for long as another one was picked up by multiple observers and reported this week by The Minor Planet Center (MPC) at Harvard University. Unlike ‘Oumuamua, this one is definitely a comet and has been identified earlier enough in its trip through the solar system to be analyzed intensely – possibly revealing where it came from and how astronomers can locate more of them.

‘Oumuamua

“The comet’s current velocity is high, about 93,000 mph [150,000 kph], which is well above the typical velocities of objects orbiting the sun at that distance. The high velocity indicates not only that the object likely originated from outside our solar system, but also that it will leave and head back to interstellar space.”

The BBC reports that object gb00234, now known as Comet C/2019 Q4, was discovered by amateur (but experienced) astronomer Gennady Borisov on August 30th, 2019, at the Crimean Astrophysical Observatory in Bakhchysarai. When he noticed it, C/2019 Q4 was three astronomical units (450 million km) from the Sun. Since then, other astronomers have seen its tail – confirming C/2019 Q4 is a comet – and measured its eccentricity at 3.2, based on current observations. A perfect circle has an eccentricity of 0, while a closed elliptical orbit ranges from 0 to 1. Anything greater than one indicates an arc-shaped trajectory and is likely an interstellar comet or object making a one-time visit. While not confirmed yet, together these make Comet C/2019 Q4 the first ‘true’ comet to visit use from outside our solar system.

Unless it’s a spaceship.

Good point. Anyone?

Unlike ‘Oumuamua, whose asteroid-or-comet nature still gets debated, this one is definitely a comet. If it is unequivocally interstellar, it’ll be fascinating to see how its composition (spectral properties) compare to the variety we see in comets from our own solar system.

Astrophysicist Karl Battams, from the Naval Research Laboratory in Washington DC, tweeted an end to that comet-asteroid-spaceship-or-what debate which has trailed ‘Oumuamua like a tail (if it had one) since it was discovered hightailing out of here. Comet C/2019 Q4 will have plenty of eyes on it as it will be visible to even low-powered professional telescopes for at least a year, including when it makes its turn around the sun (perihelion) around December 10. However, the MPC leaves an opening for the unusual:

“Absent an unexpected fading or disintegration, [C/2019 Q4] should be observable for at least a year.”

In lieu of seeing windows with aliens waving out of them, an “unexpected disintegration” would be the next coolest thing.
