Estonians at European Space Agency Help Turn Space Dreams Into Reality (Source: ERR)
A group of Estonians working at a European Space Agency research hub in the Netherlands are helping design, test and launch missions, bringing complex space systems to life. They are part of the team at the European Space Research and Technology Center (ESTEC), the agency's main research hub, where about 3,200 staff develop satellites and missions from concept to launch. 

Estonia joined the ESA in 2015. The agency serves as Europe's multinational counterpart to NASA and other countries' national space agencies, with its ESTEC center, located just north of The Hague, focused on satellite design, development and testing. (4/20)

Number of Launches Expected to Soar From Virginia Spaceport Soon (Source: WAVY)
Seeing a rocket pass by in the predawn sky can be exciting, but seeing one from the Eastern Shore is even better, with the opportunity to do so expected to increase significantly in the years ahead. Rocket Lab recently announced that there would be at least 20 launches from the Mid-Atlantic Regional Spaceport in the years ahead — a big deal for Virginia’s Eastern Shore. Virginia Spaceport Authority CEO and executive director Ted Mercer said the spaceport is ready for the new rapid launch schedule. And they have been practicing how fast they can turn around a launch pad. (4/20)

Space Exploration Without Government (Source: Townhall)
Private spaceflight has a long tradition. And today it clearly dominates over state-led spaceflight. Of the 324 rocket launches worldwide last year, 165 were carried out by SpaceX. This means that a private company conducted more rocket launches than all the countries of the world combined. After SpaceX, in second place, comes the private company of the New Zealander Peter Beck, Rocket Lab. It carried out 21 successful rocket launches, almost three times as many as Europe. And of the roughly 15,000 active satellites in space, 10,000 alone are Starlink satellites.

If, in 100 years, people look back on the history of space exploration and spaceflight, the years from 1960 to 2010—when state-led spaceflight clearly dominated—may be seen as the exception. But for private spaceflight and projects such as asteroid mining or even the settlement of the Moon and Mars to have a future, one crucial condition must be met: it must be possible to acquire—or claim—land on celestial bodies as property. Under the Outer Space Treaty, this is prohibited for states, and it remains unclear whether this prohibition also applies to private individuals. But without private property, no economic system on Earth functions—why should socialism suddenly work in space? (4/21)

An Unhinged Journey Through NASA’s Manic Photo Publishing System (Source: Peta Pixel)
NASA’s historic Artemis II mission delivered many absolutely spectacular photos and inspired a new generation of people to love space exploration. It also provided a fresh opportunity to explore the often confusing, disjointed landscape that is NASA’s photo publishing system. NASA is a great organization full of exceptional people doing incredible work. However, as the Artemis II image onslaught showed, it’s not always as easy as it should be to actually see that important, often beautiful, work.

For example, when the Artemis II crew’s first photos from space were downstreamed to Earth, it was a mad rush to share them. One image ended up on NASA’s excellent Image of the Day page in Full HD resolution. Others wound up on a dedicated webpage, “Artemis II Journey to the Moon,” which is very hard to get to unless you stumble upon a link somewhere else. Then there is, of course, NASA Images, which can be accessed directly from the NASA website homepage through the top nav bar. Eventually, many images also end up on NASA’s Flickr page. (4/20)

Resilient Fungus Might Survive Mars and Space (Source: ASM)
Scientists have long known that fungi are resilient, but a new study suggests that some strains might survive every step of the long, brutal trip to Mars. In a paper published this week, researchers isolated fungal microbes from NASA cleanrooms—facilities used in the assembly, testing and launch of spacecraft—that had persisted after decontamination. When subjected to simulations of the harsh pressure, temperature and radiation conditions of space travel and Mars, asexual reproductive spores called conidia, of the fungus Aspergillus calidoustus, survived.

Scientists Found a 'Bathtub Ring' on Mars. Could it be Evidence of an Ancient Red Planet Ocean? (Source: Space.com)
A huge geological structure on Mars resembling a bathtub ring may be evidence of an ocean that once covered a third of the Red Planet's surface, a new study finds. Decades of previous research have suggested that although Mars is now famously the "Red Planet," it once possessed liquid water on its surface. However, it remains uncertain whether that water was limited to lakes and streams, or if there was enough to form long-lasting oceans. Solving this mystery could shed light on whether ancient Mars once hosted life as we know it.

Past missions to Mars have discovered many geological features that resemble shorelines. However, the shorelines are found at varying elevations across the planet. If they were truly signs of a stable ocean, they would ideally all line up at the same elevation in much the same way sea levels are consistent on Earth. (4/20)

What Christina Koch Said About Leaving Earth Is Hitting People Hard (Source: Men's Journal)
NASA astronaut Christina Koch returned from the historic Artemis II lunar flyby mission with a wealth of new research for scientists to explore — and with a new perspective about life on Earth. One week since the crew’s return to Earth, Koch posted an emotional message on social media — acknowledging the beauty of the simple things in life.

“This moment,” Koch wrote on Instagram. “People often ask if I was scared. My answer is I was aware of the risks. When I left my home for the last time on March 27, I looked around and thought about how much I loved my humble little life. Unexpectedly, a part of me started to miss it terribly for the small chance in the future that could come to be. I know a morning cup of coffee on the porch with your best friend is a simple and universally small thing. But it is also everything.” (4/19)

Blue Origin’s Failure May Hamstring NASA’s Moon Plans (Source: New York Times)
A rocket built by Jeff Bezos’ Blue Origin space company appeared to launch perfectly on Sunday, its booster even landing successfully on a barge in the Atlantic Ocean. A few hours later, however, it became clear that all had not gone well. The massive New Glenn rocket had failed in its primary task: putting a commercial satellite into the proper orbit. This is a setback not only for Blue Origin, but also possibly NASA. Although the space agency played no role in Sunday’s mission, it is counting on Blue Origin to support the Artemis moon program.

NASA’s New Superalloy (Source: Aerospace America)
The heat inside the combustion chamber of a rocket or turbine engine can create a hellscape for metal components, with temperatures often exceeding 1,000 degrees Celsius. To ensure the injectors, nozzles, preburners, shrouds and turbine blades can withstand the heat, engine designers and builders have long relied on two kinds of superalloy metal mixtures — but neither amounts to a perfect solution. Nickel-based mixtures are relatively cheap but weaken at temperatures over 1,000 C, degrees, whereas superalloys of refractory metals like niobium remain strong above 1,000 C but are up to 100 times more expensive, plus they’re corrosion-prone.

NASA might soon be able to offer a better alternative: GRX-810, a nickel-based superalloy in formulation over the last several years that combines the best attributes of today’s alloys. Early tests indicate the material retains its strength above 1,000 C while also remaining resistant to corrosion. The current phase of testing seeks to address the cost portion of the equation. Since October, researchers have been evaluating a new manufacturing method that, if successful, could expand the use of GRX-810. (3/30)
