A Southwest Research Institute (SwRI) experiment was performed aboard Blue Origin's New Shepard suborbital rocket today, which launched from Van Horn, Texas. Five variations of the tapered liquid acquisition device (LAD), which is designed to safely deliver liquid propellant to a rocket engine from fuel tanks, were aboard the rocket to evaluate their performance in microgravity.

Humans have relied on forests and trees—for shelter, food, and fuel—from the earliest times. As technology has advanced, timber has been utilized for buildings, ships, and railroads. And now we may be on the verge of taking wood into space.

Why wood? Building in space with futuristic, 'space-age' materials might seem to be the obvious choice: lumber's fragility and combustibility might seem counter-intuitive by comparison.

Therein lies the rationale for wood: as a natural, economical, carbon-based material, its production is considerably more sustainable than advanced alternatives, and its disposal—especially when dropped from orbit into the upper atmosphere—is complete and without harmful byproducts.

Moreover, earlier investigations—in earth-bound labs—have demonstrated wood's surprising ability to withstand a wide range of temperatures, from -150 to 150 degrees Celsius.

The process for the joint 3D Organoids in Space project originated from the University of Zurich (UZH) researchers Oliver Ullrich and Cora Thiel. Together with Airbus, the two pioneers in research on how gravity affects and regulates human cells have developed the process to project maturity. The Airbus Innovations team led by project manager Julian Raatschen has developed the hardware and is providing access to the International Space Station (ISS). It took the project partners only three years from idea to the first production test in space. During this time, they completed various test phases and overcame highly competitive internal selection processes.

Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. One of them is the grave risk posed by particle radiation from the sun, distant stars and galaxies.

Answering two key questions would go a long way toward overcoming that hurdle: Would particle radiation pose too grave a threat to human life throughout a round trip to the red planet? And, could the very timing of a mission to Mars help shield astronauts and the spacecraft from the radiation?
