Astronaut Blood and Urine Could Help Build Structures on the Moon

Thinking outside the box has always been a strong suit of space exploration. Whether taking a picture of the Earth in a sunbeam or attempting to land a rocket on a floating ship, trying new things has been a continual theme for those interested in learning more about the universe. Now, a team from the University of Manchester has come up with an outside-the-box solution that could help solve the problem of building infrastructure in space – use astronauts themselves as bioreactors to create the building blocks of early colonies.

Perseverance has Already Detected Over 300 Dust Devils and Vortices on Mars

Dust devils are generally used as a trope in media when the writers want to know that an area is deserted. They signify the desolation and isolation that those places represent. Almost none of the settings of those stories are close to the isolation of Perseverance, the Mars rover that landed on the planet earlier this year. Fittingly, the number of dust devils Perseverance has detected is also extremely high – over 300 in its first three months on the planet.

Astronauts Have Used Bacteria to Extract Useful Metals out of Rocks

History has viewed mining as a job that requires a lot of heavy machinery and physical labor. Pulling valuable material out of the ground has been necessary for human progress for thousands of years. That progress has led to an alternative method of getting those resources out of the Earth or other celestial bodies. The new technique relies on a symbiotic life partner that has co-habited with us for millennia – bacteria. A recent experiment conducted by ESA’s Biorock investigation team shows that this process – known as “biomining” – might be the most effective way to collect some materials in space.

Astronomers Create 3D Printed Nebulae

Visualizations can inspire creative new ways of thinking about an object. But holding that visualization in your hand adds a whole other level of impact to it. That desire for impact has led Dr. Nia Imara, an astrophysicist and artist at UC Santa Cruz, to create the first-ever 3D printed models of stellar nurseries.

Space Continues to be Hard. Firefly’s Alpha Rocket Detonates Shortly After Launch

Rocket science is hard. So far, no commercial rocket launch company has ever successfully gotten to orbit on the first try. The first flight of Firefly‘s Alpha rocket prototype did not break that streak last week when it exploded two and a half minutes after takeoff from Vandenberg Space Force Base.

NASA has too Many Spacecraft to Communicate With. Time to Build More Dishes

NASA is a sprawling organization that has to talk to everything from politicians in Washington DC to space probes that have left the solar system. Discussions with the first might be as simple as a written letter for informal conversation, while the second requires a high-power network of ground-based antennas. Known as the Deep Space Network (DSN) this series of antennas spread over three continents is the backbone of NASA’s communications with its various space probes. Now the DSN is in the process of implementing a well-deserved upgrade.

NASA is Testing out a new air Taxi Prototype

NASA is commonly thought of as America’s space agency, but its name also emphasizes another research area. The National Aeronautics and Space Administration is also America’s civilian aerospace research organization. In that role, it has been instrumental in developing new technologies ranging from rocket engines to aircraft control systems. Part of that role is running the Advanced Air Mobility (AAM) campaign to test autonomous drone technology. The latest milestone in that campaign was testing an electric vertical takeoff and landing (eVTOL) helicopter intended for eventual use as an air taxi.

A Powerful new Laser Will Enhance Adaptive Optics

In some applications, bigger lasers mean better lasers. That is the case in astronomy, where lasers are used for everything from telescope calibration to satellite communication. The European Southern Observatory (ESO) and some of its commercial partners have developed a laser 3 times more powerful than the existing industry standard. With that increased power level, the new system has the potential to dramatically improve the way telescopes deal with one of the most fundamental problems in ground-based astronomy – atmospheric turbulence.

It’s Time to Send a Lander to Mercury

So much in the astronomy community revolves around the decadal survey. Teams of dozens of scientists put hundreds of hours developing proposals that eventually try to impact the recommendations of the survey panel that influence billions of dollars in research funding over the following decade. And right now is the prime time to get those proposals in. One of the most ambitious is sponsored by a team led by researchers at John Hopkins University Applied Physics Laboratory (APL). Their suggestion – it’s time to land on Mercury.

COVID-19 Treatments Require so Much Oxygen it Could Delay Rocket Launches

Supply chains have been wreaking havoc across the industrial world. The complex web that holds the world’s economies together has been fraying at the edges, resulting in some unexpected shortages, such as a lack of rental cars in Alaska and a lack of Lunchables at the author’s local grocery store. Now there’s a supply shortage that directly ties to the pandemic that is starting to affect the space launch industry – oxygen.
