Astronauts on the International Space Station took a few minutes to play some zero-gravity baseball last week.

Thankfully, no windows were broken and no balls were lost in the neighbors yard during the stunt, which the New York Post reports was a promotion for the World Series. There was no room to run bases, but one pitch captured on video is a cool glimpse into how astronautscan blow off some steam on board the ISS.

The ISS crewmembers got their hands on a real baseball, but apparently had to replace a normal bat with a large flashlight, per the Post.

The pitch appears pretty slow whipping a fastball across a space station seems like a way to cause a catastrophe. But as Space.com reports, the astronauts were quick to take credit for throwing a 17,500 mph fastball the speed at which the International Space Station orbits Earth.

SACRAMENTO, Cali. If youve ever wanted to experience life beyond the Earths atmosphere, you may get the chance in six years.

A company has a goal to make space vacations a reality by 2025. Right now, The Gateway Foundation is developing the very first space hotel with artificial gravity.

So the Von Braun Space Station is going to be the first commercial space station with artificial gravity, said Tim Alatorre, a senior design architect with the company.

The Von Braun Rotating Space Station will basically be a space hotel for customers.

So, the station works like a bike tire, were going to have spokes coming out of the central hub. Thats where the spaceships will dock, zero gravity and then it rotates, said Alatorre. So, the rotation creates that artificial gravity on the perimeter this is where people will be living on the outside edge.

Although artificial gravity sounds like something out of science fiction, Alatorre says the science is sound. Designers will be using technology from the International Space Station.

NASA built the space station with just a few tools, one of them is the mechanical arm that we often see in the videos, said John Blinko, President of the Gateway Foundation. Its the arm that we want to adopt in our space construction and designs and schemes and so forth.

But all of this depends on Elon Musk and SpaceXs launch system.

SpaceX is developing the Super Heavy and the Starship platform. Our projections are showing the price of tickets is going to get lower as time goes on. So for right now, it could be cost prohibitive for some, but in a few short years, its going to be a common thing people do. As soon as Starship is ready to launch and is orbital, we want to be one of the first customers to launch into orbit.

In 2025, Alatorre says people will be able to vacation to space.

So, the space station is going to be a big draw to people, said Alatorre. Were going to have a hotel, restaurant, bar, gymnasium.

But its more than that. The foundation says its the first step to advancing beyond the atmosphere.

But big picture were trying to build out a space industry, said Alatorre. We want to have multiple stations in space space tourism going to the moon, going to Mars, going to other space stations. And just from a humanity standpoint, having hundreds of people being able to go up to space and look back on Earth and just know we are sharing this little blue marble. I think its going to have a profound impact on people.

Researchers from MIT will be collaborating with colleagues at the University of Colorado at Boulder on an experiment scheduled to be sent to the International Space Station (ISS) on November 2, 2019. The experiment is looking for ways to address the formation of biofilms on surfaces within the space station. These hard-to-kill communities of bacteria or fungi can cause equipment malfunctions and make astronauts sick. MIT News asked professor of mechanical engineering Kripa Varanasi and doctoral student Samantha McBride to describe the planned experiments and their goals.

Q: For starters, tell us about the problem that this research aims to address.

Varanasi: Biofilms grow on surfaces in space stations, which initially was a surprise to me. Why would they grow in space? But its an issue that can jeopardize the key equipment space suits, water recycling units, radiators, navigation windows, and so on and can also lead to human illness. It therefore needs to be understood and characterized, especially for long-duration space missions.

In some of the early space station missions like Mir and Skylab, there were astronauts who were getting sick in space. I dont know if we can say for sure its due to these biofilms, but we do know that there have been equipment failures due to biofilm growth, such as clogged valves.

In the past there have been studies that show the biofilms actually grow and accumulate more in space than on Earth, which is kind of surprising. They grow thicker; they have different forms. The goal of this project is to study how biofilms grow in space. Why do they get all these different morphologies? Essentially, its the absence of gravity and probably other driving forces, convection for example.

We also want to think about remediation approaches. How could you solve this problem? In our current collaboration with Luis Zea at UC Boulder, we are looking at biofilm growth on engineered substrates in the presence and absence of gravity. We make different surfaces for these biofilms to grow on, and we apply some of our technologies developed in this lab, including liquid impregnated surfaces [LIS] and superhydrophobic nanotextured surfaces, and we looked at how biofilms grow on them. We found that after a years worth of experiments, here on Earth, the LIS surfaces did really well: There was no biofilm growth, compared to many other state of the art substrates.

Q: So what will you be looking for in this new experiment to be flown on the ISS?

McBride: There are signs indicating that bacteria might actually increase their virulence in space, and so astronauts are more likely to get sick. This is interesting because usually when you think of bacteria, youre thinking of something thats so small that gravity shouldnt play that big a role.

Professor Cynthia Collins group at RPI [Rensselaer Polytechnic Institute] did a previous experiment on the ISS showing that when you have normal gravity, the bacteria are able to move around and form these mushroom-like shapes, versus in microgravity mobile bacteria form this kind of canopy shape of biofilm. So basically, theyre not as constrained any more and they can start to grow outward in this unusual morphology.

Our current work is a collaboration with UC Boulder and Luis Zea as the principal investigator. So now instead of just looking at how bacteria respond to microgravity versus gravity on Earth, were also looking at how they grow on different engineered substrates. And also, more fundamentally, we can see why bacteria biofilms form the way that they do on Earth, just by taking away that one variable of having the gravity.

There are two different experiments, one with bacterial biofilms and one with fungal biofilms. Zea and his group have been growing these organisms in a test media in the presence of those surfaces, and then characterizing them by the biofilm mass, the thickness, morphology, and then the gene expression. These samples will now be sent to the space station to see how they grow there.

Q: So based on the earlier tests, what are you expecting to see when the samples come back to Earth after two months?

Varanasi: What weve found so far is that, interestingly, a great deal of biomass grows on superhydrophobic surfaces, which is usually thought to be antifouling. In contrast, on the liquid-impregnated surfaces, the technology behind Liquiglide, there was basically no biomass growth. This produced the same result as the negative control, where there were no bacteria.

We also did some control tests to confirm that the oil used on the liquid impregnated surfaces is not biocidal. So were not just killing the bacteria, theyre actually just not adhering to the substrate, and theyre not growing there.

McBride: For the LIS surfaces, well be looking at whether biofilms form on them or not. I think both results would be really interesting. If biofilms grow on these surfaces in space, but not on the ground, I think thats going to tell us something very interesting about the behavior of these organisms. And of course, if biofilms dont form and the surfaces prevent formation like they do on the ground, then thats also great, because now we have a mechanism to prevent biofilm formation on some of the equipment in the space station.

So we would be happy with either result, but if the LIS does perform as well as it did on the ground, I think its going to have a huge impact on future missions in terms of preventing biofilms and not getting people sick.

Fundamentally, from a science point of view, we want to understand the growth of these films and understand all of the biomechanical, biophysical, and biochemical mechanisms behind the growth. By adding the surface morphology, texture, and other properties like the liquid-impregnated surfaces, we may see new phenomena in the growth and evolution of these films, and maybe actually come up with a solution to fix the problem.

Varanasi: And then that can lead to designing new equipment or even space suits that have these features. So thats where I think we would like to learn from this and then propose solutions.

(WISH) Houston, theres been a breakthrough in the baking situation from space.

For the first time, chocolate chip cookies will be made out of this world.

Sure, astronauts have been able to get their hands on Tang and freeze-dried ice cream in the past, but a warm, fresh baked cookie was never on the menu until now.

A company called Zero G Kitchen has developed a special oven that will be shot into space on Saturday.

Until this mission, astronauts were only able to reheat their food in space, there was no actual baking.

But when the new oven is installed on the International Space Station, it will be the first appliance for a kitchen of the future.

No one is yet sure what cooking will be like in zero gravity, but theyll soon find out.

WASHINGTON Made In Space's new satellite-construction robot could herald a new generation of autonomous machines working on the moon and perhaps even Mars.

At the International Astronautical Congress (IAC) here on Oct. 25, representatives from NASA and the California-based company Made In Space talked about the forthcoming opportunities for in-space manufacturing, which they say will reduce the costs and complications of shipping stuff around the solar system.

One of the big advantages of in-space manufacturing is that it allows the construction of components that are too big to fit atop a rocket, as well as fragile structures that cannot survive the rigors of launch, said Justin Kugler, Made In Space's vice president of advanced programs and concepts. He said designers can thus optimize for "the design and service life of a satellite, as opposed to surviving those first 15 minutes to get out of [Earth's] gravity well and the atmosphere."

One of the first major tests of this technology will be Archinaut One, a spacecraft Made In Space is developing with the help of $73.7 million in NASA funding. Archinaut One, which is expected to launch as soon as 2022, will 3D-print two 32-foot-long (10 meters) beams in Earth orbit, one on either side of the spacecraft. These beams will then unfurl solar arrays that can generate five times more power than traditional panels used by similar-size spacecraft, NASA officials said in July.

During the IAC presentation, Kugler said that Archinaut One will do more with less, because the craft will overcome traditional small-satellite power constraints. Made In Space will even use the opportunity to test a broadband-radio frequency instrument from Northrop Grumman, he added.

"This is not just a technology demonstration but a functional demonstration of end-to-end capability," Kugler added.

In-space manufacturing is already happening on the International Space Station, said Raymond Clinton, the associate director of the science and technology office at NASA's Marshall Space Flight Center in Alabama.

Facilities aboard the orbiting lab today include two 3D printers built by Made In Space, as well as plastics printers. This work takes place on the U.S. National Laboratory managed by NanoRacks, a company that assists other entities in getting experiments or equipment to space.

As NASA pushes to return humans to the moon in 2024, the agency anticipates growing the capability to do manufacturing on the lunar surface. NASA's lunar surface innovation initiative calls for a series of demonstration missions through the 2020s that will eventually help the agency and its partners prepare for a human mission to Mars. NASA Administrator Jim Bridenstine has said that the agency aims to launch this next giant leap to the Red Planet in 2033 or 2035.

"This is how we see in-space manufacturing moving forward," Clinton said. "And as the agency has said, we are going to the surface of the moon to demonstrate the technologies we will need when we go to Mars. That is the next step."

NASA is already planning for lunar manufacturing through the Commercial Lunar Payload Services (CLPS) program, which has selected nine companies for possible future missions; more may be on the way after a selection process that closed a few weeks ago.

At first, the tech will be tested on Earth. NASA is engaging in a drill "down selection" for future CLPS missions, Clinton said, as well as producing high-fidelity lunar regolith (soil) simulant to help missions prepare for the dust on the lunar surface. Missions that will help enable astronauts to "live off of the land" on the moon by exploiting lunar resourcesshould come in the mid-2020s, including extractions of consumables (such as water) from the regolith.

Made In Space's Kevin DiMarzio called the forthcoming decade a "new era" in in-space manufacturing not only because of the moon-to-Mars goals, but also because in-space manufacturing will make space exploration cheaper for both robotic and human missions.

"It's increasing the capability of the density of what we can send to space," explained DiMarzio, the company's vice president of business development, "[which means] sending more stuff that can do more things in a cost-efficient package."

Off-Earth Manufacturing Could Help Astronauts Explore the Moon and Mars - Space.com

WASHINGTON My spacecraft flew through the shadow of the moon and into orbital sunrise, and there it was: Earth hovering as a blue marble in the blackness of space.

I began to think of the immortal words of astronomer Carl Sagan: "That's here. That's home. That's us. On it [is] everyone you love, everyone you know." And to my delight, my commander, Dutch astronaut Andr Kuipers, began to quote Sagan, almost word for word.

I wasn't really in space, of course. That would be an incredible opportunity, but for now, this is the next best thing. I experienced the "overview effect" of seeing Earth as a whole planet last week here at the International Astronautical Congress, where Dutch nonprofit SpaceBuzz toured a minibus outfitted with a virtual reality show hosted by an avatar of Kuipers.

SpaceBuzz's story starts with Wubbo Ockels, the first Dutch astronaut in space, on shuttle mission STS-61A in 1985. On his deathbed in 2014, Ockels said: "If I could transfer the experience I had in space then that would change your life on Earth," according to SpaceBuzz board member Zoran van Gessel.

"That is the overview effect," van Gessel said. "It's obviously too expensive to send people in space by the billions, but with 3D virtual technology, we can mimic that."

Thousands of Dutch children have already experienced this virtual reality show, but their journey doesn't begin by strapping on the virtual reality helmets. Rather, it starts in the classroom. They undergo a mini "astronaut training school," where they, sometimes with the help of adults, pass basic tests about what it would be like to live in space.

Then comes the fun part for these 10- to 12-year-olds, who are very familiar with 3D apps and games. They sit in the chairs of the SpaceBuzz bus, grab their headsets and find themselves immediately inside a spacecraft. Kuipers' avatar guides them through launching into space. They "fly" around the world, witnessing sights such as shimmering auroras and fishing boats on the sea. Occasionally, space hardware including the International Space Station floats by. The journey culminates with a jaunt to the moon, where Earth appears dramatically different from so far away.

SpaceBuzz wants to expose children to STEM (space, technology, engineering and math) topics, although the nonprofit says whatever path these kids choose is just fine. "We want to make sure that children respond to the whole space experience in their own way," van Gessel said, acknowledging that some kids may want to go into different fields while still remembering the experience of space.

The SpaceBuzz "spacecraft" has toured the Netherlands and the United States; it made stops in Houston and Washington, D.C., in October.

(Image credit: SpaceBuzz/Remko de Waal)

The SpaceBuzz bus is the first of its type, supported by a group of private individuals (including the Kuipers family). SpaceBuzz representatives said the proof of concept has been so successful that the company plans to build a second bus and extend the experience online to bring it to more children. Future iterations of the virtual reality experience could include interactive elements, allowing children to ask and answer questions about space during their mission.

In addition to benefiting children, the venture uses 3D technology to essentially replicate in-demand astronauts like Kuipers. "We learned afterwards that Andr, being the only Dutch astronaut alive, gets hundreds and hundreds and hundreds of requests year after year to explain to children about space, but obviously he can't do it. It's not workable," van Gessel said.

Children and adults alike get to experience the "overview effect" the emotions upon seeing Earth as a blue marble from space while taking part in the virtual reality show run by SpaceBuzz.

(Image credit: SpaceBuzz/Remko de Waal)

SpaceBuzz recently showcased its technology at a gathering of astronauts, the Association of Space Explorers, in Houston, where space flyers, including Catherine "Cady" Coleman and Chris Hadfield, got to experience the show for themselves.

"We can share it with any country, or any astronaut, or any organization, that is willing to support our goal to share the overview effect with as many children as possible," van Gessel said. "But what we've learned is, it also works on adults," he added with a grin.

Components for Chinas third Long March 5 rocket arrived at the countrys southern launch base this week as teams prepare for the first flight of the heavy-lift launcher since a 2017 mission ended in failure.

The return-to-flight mission, expected in the second half of December, is a major test of the heavy-lift rocket before China commits to launching a Mars rover and a lunar sample return mission on Long March 5 vehicles next year.

Hardware for the third Long March 5 rocket arrived Oct. 27 at Qinglan Port on Hainan Island aboard two Yuanwang transport ships, which are specially outfitted to ferry rocket components, according to the China Aerospace Science and Technology Corp., or CASC, the primary state-owned contractor responsible for Chinas space program.

Boosters and stages for the Long March 5 rocket were loaded into the two Yuanwang vessels at Tianjin in northern China, the site of the Long March 5 factory. The ships departed Tianjin on Oct. 22 for the five-day journey to Hainan Island, Chinas southernmost launch site, according to CASC.

The containers were delivered by road to the Wenchang space center on the eastern coast of Hainan Island.

The Long March 5s core stage size with a diameter of 16 feet, or 5 meters and the Wenchang launch sites island locale require the rocket to be delivered by ship, rather than by train.

Wenchang is Chinas newest spaceport, and has hosted four space launches to date. Two Long March 5s and two flights by the smaller Long March 7 have lifted off from Wenchang since the launch base began operations in 2016.

After a successful inaugural launch in 2016, the second Long March 5 rocket failed during the launch of a massive experimental communications satellitein July 2017.

Investigators traced the cause of the launch failure to a turbopump on one of the Long March 5s two YF-77 first stage engines. The YF-77 engines power the Long March 5s core stage, each consuming liquid hydrogen and liquid oxygen propellants and producing up to 157,000 pounds of thrust in vacuum.

The YF-77 engine failure occurred in a complex thermal environment around six minutes after liftoff, leading to an instantaneous loss of thrust, according to Chinese investigators. Engineers redesigned the engine turbine exhaust structure for future Long March 5 missions, forcing officials to scrap engine parts already in stock.

The changes led to a gap of more than two years between the second and third Long March 5 flights, assuming the next rocket takes off as scheduled in December. In the interim between launches, engineers conducted test-firings of the modified YF-77 engine to verify the design changes, according to theState Administration for Science, Technology and Industry for National Defense, or SASTIND, the Chinese government agency that oversees the countrys space activities.

The YF-77 engines were developed specifically for the Long March 5, the largest rocket in Chinas fleet. The Long March 5 launches with four kerosene-fueled strap-on boosters, each powered by two YF-100 engines, to augment the thrust from the core stages twin YF-77 engines.

Two restartable hydrogen-fueled YF-75D engines drive the Long March 5s second stage.

The heavy-lift rocket blasts off with some 2.4 million pounds of thrust, and has the capability to deliver up to 14 metric tons nearly 31,000 pounds to geostationary transfer orbit, a popular target orbit for large communications satellites.

The payload for the third Long March 5 launch is named Shijian 20, an experimental satellite to replace the Shijian 18 satellite lost on the 2017 launch failure.

Like Shijian 18, the Shijian 20 satellite is based on the newest Chinese spacecraft platform, designated the DFH-5.

Developed by the China Academy of Space Technology, the DFH-5 design is bigger and more capable than Chinas previous satellites, providing more power for communications payloads and additional data throughput for Internet providers, television broadcasters and data networks.

The Shijian 18 satellite lost in the 2017 launch failure hosted a laser communications instrument for high-speed data links, and new high-power ion thrusters. Shijian 20 is expected to carry similar payloads to conduct technology demonstrations in geostationary orbit.

A successful return-to-flight by the Long March 5 late this year would allow China to launch a pair of ambitious robotic deep space missions using Long March 5 rockets in 2020.

Chinas first Mars rover is scheduled for launch on a Long March 5 in mid-2020, and the next mission in Chinas lunar program Change 5 will also require the lift capability of the Long March 5 next year to depart Earth.

Change 5 will attempt to land on the moon, collect samples, and bring the materials back to Earth. It would be the first lunar sample return mission since the 1970s.

The launch of Change 5 was delayed during the grounding of the Long March 5 after the 2017 failure.

China also plans to debut a variant of the Long March 5, called the Long March 5B, next year. The Long March 5B uses the same booster configuration as the already-flying Long March 5 design, but will launch without a second stage.

The Long March 5B is configured to loft heavy modules for Chinas planned space station in low Earth orbit, which is scheduled to be completed in 2022.

WASHINGTON Take it or leaf it: Mars won't offer the sort of veggie options on display at your neighborhood supermarket.

We humans deign to munch on the order of 150 or 200 species of plants all told. And not all of those would make the journey with astronauts to the Red Planet. So far, NASA has focused its vegetable-growing efforts on lettuce, which astronauts tend to while they live on the International Space Station. The orbiting laboratory poses different challenges than the Red Planet's surface, however, and crops that Mars visitors can expect to rely on may not be to everyone's taste.

"In fact, in this particular area the soils are more alkaline so this would be OK for growing asparagus and beans and not potatoes," NASA chief scientist Jim Green said during a presentation held here last week as part of the International Astronautical Congress of soil studied by NASA's Curiosity rover. "If I had to eat asparagus for three years, I think I'd just take my helmet off and walk outside," he added.

(Reminder: If you actually want to go to Mars, you're going to need to tackle several more pressing challenges than the salad bar options. Like, you know, breathing.)

However you feel about asparagus, Green's statement is a testament to just how much scientists have learned about Mars and its soil. Curiosity was always designed to be a geologist and has been particularly adept at telling scientists about the Martian soil around its landing spot in Gale Crater.

"We find that we can get carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur out of the soil," Green said. "There's nitrates in the soils and [we've learned] that they are moist."

Scientists know all that about soil they have never seen for themselves or studied in their own laboratory. They know that based on data beamed back by dozens of orbiters and eight successful missions to the surface, and none of those robots has ever come back.

Curiosity and its drill were particularly exciting developments for the study of Martian soil, Green said, as the instrument soon hit distinctly different soil than what was on the surface. "What was really exciting when we first dug into this red soil is [that] grey material started coming out," he said. "This tells us that Mars' history is really quite exciting," with a vibrant history of water flowing over the planet's surface.

But despite what they've learned at a distance, scientists still hope to get a better look at that soil, in laboratories here on Earth. They're busy thinking through a mission that could deliver such samples in 2031. Their most pressing question won't be how well it would suit the needs of asparagus, but the analysis may still offer some tips.

A UFO has been captured hovering over a San Diego motorway, a driver has bizarrely claimed.

The clip, which was captured last week in downtown San Diego, California, US, has left thousands of conspiracists making wild claims.

Nene Angulo captured the footage from his windscreen as he drove down the motorway.

In the distance, a round white object can be seen aimlessly hovering in the clear sky.

As Nene drives on, a smaller white object attached to its underside becomes visible.

He said: "Can you see that s**t? It looks like a big space station.

"But it's just floating in the sky, not moving at all."

As he carries on driving down the motorway, Nene zooms in on the object.

He adds: "What the f**k is that? It's not a balloon.

"It's just floating, silently."

YouTube conspiracist The Hidden Underbelly 2.0 uploaded the clip only days ago.

More than 1,000 people have since watched the video, leaving many to believe the driver had captured a UFO.

One person said: "This is awesome. One of the best UFO videos I've seen yet."

"This is wild," a second added.

However, many believe the driver captured DARPA's unmanned aircraft tracking system that was due to be tested in the skies last week.

The test period, which started Monday and ran through to Friday, focused on a potential drone tracking system for large cities, which present tracking challenges due to tall buildings.

These tests involved sensors placed on two tethered aerostat balloons roughly 500 feet above ground level while optical sensors were placed on hovering drones and building tops.
