Cygnus Boosts the International Space Station for the First Time. NASA Can Now Potentially Keep the Station Aloft Without Russia’s Progress Spacecraft

Northrup Grumman’s Cygnus cargo spacecraft conducted a successful reboost of the International Space Station over the past weekend, on Saturday, June 25, 2022. The Cygnus NG-17 “Piers Sellers” is the first US-based spacecraft to provide a substantial orbital adjustment to the ISS since the space shuttles retired in 2011. Russia’s Progress cargo spacecraft has been the primary source for station reboosts, attitude control, and debris avoidance maneuvers.

“This reboost of the ISS using Cygnus adds a critical capability to help maintain and support the space station,” said Steve Krein, vice president, civil and commercial space, tactical space systems, Northrop Grumman, in a press release. “It also demonstrates the enormous capability Cygnus offers the ISS and future space exploration efforts.”

Fire Acts Strangely in Microgravity. Astronauts Have Lit More Than 1,500 Fires on the Space Station to Figure Out Why

Ever since childhood, we were all told to never play with fire. Despite it being relevant to our everyday lives, to include heating our homes and water, cooking our food, producing electricity, and more, fire is extremely dangerous. We were all indoctrinated more with how to put out fires instead of how to start one. We’ve all been told about its destructive properties if mishandled, and that fire needs to be controlled. One of the perks of adulthood, and especially being a scientist, is you get paid to play with fire. Despite fire’s complexities, there’s still a lot we don’t know about its behavior. With more and more of humanity traveling to space and living in microgravity, it’s important to learn about how fire behaves in this unique environment to better prepare ourselves for worst case scenarios. But what if we could also control fire so it’s not as dangerous and less destructive to the environment back here on Earth?

Spacesuits are Leaking Water and NASA is Holding off any Spacewalks Until They can Solve the Problem

NASA’s spacesuits are getting old. The extra-vehicular mobility units – EMUs for short – were designed and built for spacewalks outside NASA’s space shuttles, which flew for the last time in 2011. Nowadays, the EMUs are an integral part of maintaining and upgrading the International Space Station (ISS) exterior, providing the crew with the ability to live and work in the vacuum of space for extended periods of time (spacewalks regularly last from 6 to 8 hours). However, at the end of the most recent spacewalk on March 23, NASA astronaut Kayla Barron discovered water in the helmet of German astronaut Matthias Maurer while she helped him remove the suit.

The Lunar Eclipse, Seen From the International Space Station

If you were able to witness the lunar eclipse on May 15-16, 2022, the view of the dark red Moon was stunning. But what would such an eclipse look like from space?

Wonder no longer. ESA/Italian astronaut Samantha Cristoforetti captured a series of photos of the lunar eclipse from her unique vantage point aboard the International Space Station (ISS).

Crew-4 is off to the Station

Name someone who at some point in their life didn’t want to be an astronaut. The answer is no one. Ask any kid what they want to be when they grow up and they all say an astronaut. Being an astronaut is the ultimate dream job for everyone of all ages. Why? Because you get to go to space, and there’s nothing cooler than going into space. For context, even if you’re not a sports fan you have watched the Super Bowl at least once in your life. It is one of the most watched and most lauded sports championship games in the entire world, and yet despite all its media attention and halftime shows and all-time great finishes, the Super Bowl still holds a candle to being able to go to space. Eat your heart out, Tom Brady. Going into space is just awesome, and there’s nothing like it.

Axiom’s First Astronauts Return From International Space Station

Axiom Space’s first crew of private astronauts is back on Earth after a 17-day orbital trip that included a week of bonus time on the International Space Station. The mission ended at 1:06 p.m. ET (5:06 p.m. GMT) today when SpaceX’s Crew Dragon Endeavour splashed down in the Atlantic Ocean off the coast of Florida.

Former NASA astronaut Michael Lopez-Alegria was the commander for the homeward trip, accompanied by three investors who each paid Axiom $55 million for their rides: Ohio real-estate and tech entrepreneur Larry Connor, who served as the mission pilot, plus Canada’s Mark Pathy and Israel’s Eytan Stibbe.

“Welcome back to planet Earth,” SpaceX’s mission control operator Sarah Gillis told the crew. “The Axiom-1 mission marks the beginning of a new paradigm for human spaceflight. We hope you enjoyed the extra few days in space.”

Axiom-1 began on April 8 with the Florida launch of a SpaceX Falcon 9 rocket. The trip was originally supposed to last about 10 days, but concerns about weather in the splashdown zone delayed the descent. Because of the way their fares were structured, Axiom’s customers didn’t have to pay extra for the extension.

Stunning Image of ISS Taken From the Ground Shows two Spacewalking Astronauts

In our age, we’ve grown accustomed to pictures of astronauts inside the International Space Station, as they float in zero-G and tend their science experiments. We’re even getting used to images of spacewalking astronauts. But this is something new.

NASA Astronaut and Cosmonauts Land Safely Together in Kazakhstan

After much speculation and concern the past month whether Russia would allow a US astronaut to ride back to Earth in a Soyuz spacecraft, Mark Vande Hei and two cosmonauts landed safely in Kazakhstan on March 30.

Mostly lost amid the political tensions due to Russia’s invasion of Ukraine, Vande Hei quietly set a record for the longest single spaceflight by an American, at 355 days. Vande Hei eclipsed astronaut Scott Kelly’s seemingly more heralded long-duration mission on the International Space Station in 2015, when he and Cosmonaut Mikhail Kornienko spent 340 days in space. Cosmonaut Pyotr Dubrov also spent 355 days on his first spaceflight, along with Vande Hei.

As countries around the world respond to Russia’s invasion of Ukraine with sanctions aimed at crippling Moscow and Vladimir Putin, the global cooperation in space exploration that has been forged over the past 30-plus years will certainly be impacted.
