Researchers at the University of Colorado Boulder have developed experiments to replicate the chemical reactions of the Interstellar Medium, using techniques like laser cooling and mass spectrometry to observe interactions between ions and molecules.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there.

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other.

Finding water on distant planets and moons in our solar system is a challenge, especially when the instrument is thousands of kilometers away from the surface, but scientists presenting at the European Geosciences Union General Assembly describe how ground-penetrating radar is used to discover bodies of water below the surface of distant planets and they are on their way to Jupiter.

As NASA focuses on exploring the Moon, Mars, and the solar system for the benefit of humanity, the agency’s Space Technology Mission Directorate (STMD) is shifting how it prioritizes technology development. As part of this refinement effort, NASA is asking the American aerospace community for feedback on nearly 190 national space technology needs – or shortfalls – it has identified for future space exploration and science endeavors.

“Our ambitious future missions pose many unique challenges, and STMD is positioned – as the nation’s tech base for civil space – to innovate and advance solutions for those problems,” said Dr. Kurt Vogel, associate administrator for Space Technology at NASA Headquarters in Washington. “STMD is developing many critical technologies, but shifting to a more open and collaborative approach allows us to better prioritize our efforts and align with key stakeholder needs while ensuring we all get the most bang out of our investments.”

NASA aims to collect broad aerospace community feedback on critical technology shortfalls – like additive manufacturing, cryogenic fluid management, in-situ resource utilization, and others – ahead of future operations on the Moon and Mars. Understanding and prioritizing the most important and impactful efforts allows STMD to appropriately direct available resources to best support mission needs for NASA and the nation.

Jason Cassibry, Ph.D., explains his team’s research and experiments in the areas of fusion, warp drive and even a mention of antigravity propulsion. A mention is also made as to what happened to Ning Li (more on that in a subsequent video). This was a presentation to the Huntsville Alabama L5 Society, a chapter of the National Space Society. There is a lot of technical discussion with the audience who were almost all engineers and scientist.
