Episode 21 — How Aircraft Propellers Drove The Aeronautical Revolution

Posted by in categories: military, space travel

Great new episode with the Smithsonian’s Jeremy R. Kinney. We discuss all aspects of how the seemingly mundane propeller drove the 20th Century’s revolution in aerospace and helped usher in an era of global warfare, travel, and trade.


Without the lowly propeller, global trade and commerce and freedom of movement as we knew it prior to Covid would have never had the opportunity to flourish. Special guest Jeremy R. Kinney, Chair of the Aeronautics Department at the Smithsonian Institution’s National Air and Space Museum in Washington, D.C., provides a fascinating narrative to how and why advances in aircraft propeller technology enabled aerospace to revolutionize global warfare, travel, and trade. Author of “Reinventing the Propeller,” Kinney and I discuss many underappreciated aspects of this aeronautical workhorse.

Artemis Accords: why many countries are refusing to sign moon exploration agreement

Posted by in categories: geopolitics, space travel, treaties

Eight countries have signed the Artemis Accords, a set of guidelines surrounding the Artemis Program for crewed exploration of the moon. The United Kingdom, Italy, Australia, Canada, Japan, Luxembourg, the United Arab Emirates and the US are now all participants in the project, which aims to return humans to the moon by 2024 and establish a crewed lunar base by 2030.

This may sound like progress. Nations have for a number of years struggled with the issue of how to govern a human settlement on the moon and deal with the management of any resources. But a number of key countries have serious concerns about the accords and have so far refused to sign them.

Previous attempts to govern space have been through painstakingly negotiated international treaties. The Outer Space Treaty 1967 laid down the foundational principles for human space exploration – it should be peaceful and benefit all mankind, not just one country. But the treaty has little in the way of detail. The moon Agreement of 1979 attempted to prevent commercial exploitation of outer-space resources, but only a small number of states have ratified it – the US, China and Russia haven’t.

Rocket builder Firefly Aerospace aims for first launch from California in late December, CEO says

Posted by in category: space travel

Firefly Aerospace currently plans for its maiden Alpha rocket launch to happen as early as Dec. 22, co-founder and CEO Tom Markusic told CNBC, as his company prepares for the next major milestone in its plan to offer a variety of space transportation services.

Markusic is confident in the launch date because of the “rigid” requirements of Vandenberg Air Force Base in California, where Firefly is finishing up work to prepare the launchpad at SLC-2. While “everything is susceptible to surprises,” with room in the schedule to launch as late as Jan. 31, Markusic said the “full gamut of rules” at Vandenberg means the company has put extra work into certification for Alpha’s first launch.

“We took the hard route to flight, and that was by going to a launch range that has very strict requirements,” Markusic said. “So our design has been highly vetted, as we have a lot of requirements that are put on us by the range and that makes the rocket ultimately more reliable.

Researchers Built a “Gravity Suit” to Keep Astronauts Healthy

Posted by in category: space travel

“The mobile gravity suit is a small, untethered, and flexible intravehicular activity (IVA) suit,” the researchers wrote in their paper published in the Frontiers in Physiology journal.

The idea is to give astronauts maximum flexibility while on board a spacecraft, without reducing crew time. “With the gravity suit, astronauts will be able to float freely around the space station while adhering to their every day tasks,” the paper reads.

“The negative pressure is generated by its own portable vacuum system, ensuring full mobility, and user-control,” the paper reads.

The Direct Fusion Drive That Could Get Us to Saturn in Just 2 Years

Posted by in category: space travel

Suddenly, a billion miles doesn’t seem so far.


Experts say the right kind of propulsion system could carry spacecraft to Saturn in just two years. The direct fusion drive (DFD), a concept being developed by Princeton Plasma Physics Laboratory, would make extremely fast work of the nearly billion miles between Earth and Saturn.
