Probing deeper into origins of cosmic rays

Posted by in categories: information science, particle physics, space travel

Cosmic rays are high-energy atomic particles continually bombarding Earth’s surface at nearly the speed of light. Our planet’s magnetic field shields the surface from most of the radiation generated by these particles. Still, cosmic rays can cause electronic malfunctions and are the leading concern in planning for space missions.

Researchers know cosmic rays originate from the multitude of stars in the Milky Way, including our sun, and other galaxies. The difficulty is tracing the particles to specific sources, because the turbulence of interstellar gas, plasma, and dust causes them to scatter and rescatter in different directions.

In AIP Advances, University of Notre Dame researchers developed a to better understand these and other cosmic ray transport characteristics, with the goal of developing algorithms to enhance existing detection techniques.

The Inspiration4 astronauts are training hard for their private launch on a SpaceX rocket

Posted by in categories: biotech/medical, space travel

Four private astronauts have been strapped into a centrifuge, climbing mountains and learning how to fly a spacecraft ahead of their flight to space — the first-ever crewed space mission without any “professional astronauts” on board.

The crew is preparing to launch this upcoming September as part of the Inspiration4 mission aboard a SpaceX Crew Dragon spacecraft. The mission, privately chartered by billionaire Jared Isaacman to support St. Jude Children’s Research Hospital, recruited three crew members in addition to Isaacman for the trip which will fly around the Earth for several days. The crew includes Isaacman, St. Jude physician’s assistant and childhood bone cancer survivor Hayley Arcenaux, data engineer Chris Sembroski and geoscientist, science communicator and artist Sian Proctor.

HALO & HARC Balloon Launched Hybrid Rockets with Bill Brown

Posted by in categories: habitats, space travel

See how we developed Hybrid rockets and launched them from high altitude balloon initially with the Huntsville Alabama L5 Society (HAL5)‘s High Altitude Lift-Off (HALO) Program and later with our High Altitude Research Corporation (HARC). See our Balloon Launch Return Vehicle (BLRV) and our HARC Cheap Access to Space (CATS) Prize rocket. Hear some of our war stories from these adventures. A balloon launched rocket is known as a rockoon.

Watch next week for a related interview, The Inside Scoop on Virgin Galactic with Tim Pickens.

NASA 3D-Printed Engine Hardware Passes Cold Spray, Hot Fire Tests

Posted by in categories: 3D printing, space travel

3D-printed parts can make rocket engines lighter, less expensive and more efficient.

At Marshall, we’re working with our industry partners to test the latest advances in additive manufacturing technologies:


NASA is partnering with Aerojet Rocketdyne to advance 3D printing technologies, known as metal additive manufacturing, and its capabilities for liquid rocket engines in landers and on-orbit stages/spacecraft.
