Branson Beats Bezos to Space History and Flight Analysis with Tim Pickens

Breaking — Branson Beats Bezos to Space! Some history of the Virgin Galactic propulsion development, flight analysis and more background with Tim Pickens.

Tim Pickens is an entrepreneur, inventor, innovator, engineer and educator. He specializes in commercial space, technical product development and solutions, and business consulting and strategy for space and technical companies. Pickens’ 25+ years of experience in the aerospace industry, specializing in the design, fabrication and testing of propulsion hardware systems, has earned him a reputation as one of the industry’s leaders in these areas. Early in his career, Pickens served as propulsion lead for Scaled Composites on SpaceShipOne, winner of the $10 million Ansari X Prize. He also worked for small hardware-rich aerospace companies in Huntsville, and later supported the Virgin Galactic’s SpaceShipTwo venture.

Researchers Discover Orbital Patterns of Trans-Neptunian Objects Vary Based on Their Color

Data collected can be used to provide new insights into the evolution of the Kuiper Belt, and the larger solar system.

Trans-Neptunian Objects (TNOs), small objects that orbit the sun beyond Neptune, are fossils from the early days of the solar system which can tell us a lot about its formation and evolution.

A new study led by Mohamad Ali-Dib, a research scientist at the NYU Abu Dhabi Center for Astro, Particle, and Planetary Physics, reports the significant discovery that two groups of TNOs with different surface colors also have very different orbital patterns. This new information can be compared to models of the solar system to provide fresh insights into its early chemistry. Additionally, this discovery paves the way for further understanding of the formation of the Kuiper Belt itself, an area beyond Neptune comprised of icy objects, that is also the source of some comets.

Muon g-2 Experiment Results – Profound Implications for the History of the Universe

Experiment opens up field for new physics, say Fermilab, UChicago scientists.

The news that muons have a little extra wiggle in their step sent word buzzing around the world this spring.

The Muon g-2 experiment hosted at Fermi National Accelerator Laboratory announced on April 7 that they had measured a particle called a muon behaving slightly differently than predicted in their giant accelerator. It was the first unexpected news in particle physics in years.

A Small Satellite With a Solar Sail Could Catch up With an Interstellar Object

When Oumuamua, the first interstellar object ever observed passing through the Solar System, was discovered in 2017, it exhibited some unexpected properties that left astronomers scratching their heads. Its elongated shape, lack of a coma, and the fact that it changed its trajectory were all surprising, leading to several competing theories about its origin: was it a hydrogen iceberg exhibiting outgassing, or maybe an extraterrestrial solar sail (sorry folks, not likely) on a deep-space journey? We may never know the answer, because Oumuamua was moving too fast, and was observed too late, to get a good look.

It may be too late for Oumuamua, but we could be ready for the next strange interstellar visitor if we wanted to. A spacecraft could be designed and built to catch such an object at a moment’s notice. The idea of an interstellar interceptor like this has been floated by various experts, and funding to study such a concept has even been granted through NASA’s Innovative Advanced Concepts (NIAC) program. But how exactly would such an interceptor work?

A new paper released on ArXiv on June 27th explores one possible mission design. Derived from the NIAC study, the proposal suggests combining solar sail technology with the ability to miniaturize space probes to small, lightweight sizes.

Scientists Solve 40-Year Mystery Over Jupiter’s Spectacularly Powerful X-ray Aurora

A research team has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes.

A research team co-led by UCL (University College London) has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes.

The X-rays are part of Jupiter’s aurora — bursts of visible and invisible light that occur when charged particles interact with the planet’s atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Jupiter’s is much more powerful, releasing hundreds of gigawatts of energy, enough to briefly power all of human civilization.*.
