Traditionally, National Laboratories are federal research assets that are primarily focused on critical government scientific programs that cannot be accomplished any other way. Any excess capacity can then be made available for non-governmental use through various mechanisms. That was precisely the thinking behind designating the US Segment of the ISS as a National Lab and requiring it be managed by a nonprofit. The policymakers of 2010 intended CASIS to focus on using the ISS as a catalyst for terrestrial breakthrough innovation such that we could generate independent demand for access to LEO. The primary value of CASIS has always been in the allocation of the Congressionally-mandated 50% of all available ISS resources for research, not its relatively meager budget for grants. Every Fortune 500 company I met with when I worked at CASIS understood this and saw the ISSNL as a way to conduct heavily-subsidized science that they wouldn’t otherwise get to do. Just like the terrestrial labs. The mission of driving entrepreneurial innovation and commercialization is a separate economic development function that has always taken a back seat to a continued focus on basic science, even when grant funding from programs like In-Space Production peaked. In my opinion, it is a travesty that these activities have never been funded or supported to the same level as basic science and future destinations. With the pending transition to the commercial Low Earth Orbit era, we have a chance to convince policymakers to do this differently. Early stage support for entrepreneurship and product development must be considered independently of basic science, perhaps even in entirely separate organizations. Perhaps even outside of NASA.

https://lnkd.in/esRe-GMc The Tartarian Question (in my opinion) is an accumulation of a variety of questions which connect multiple scientific technologies (natural/manmade) to a unified existence. Puzzling? yes! Fascinating? Of course! Viable? Very possible! If history is rewritten by the victors and many of the victors were corrupted (as history has proven time & time again) who’s to say Tartarian culture was not a thing at some point of time? Did we have a dimensional shift? Did cern zap us all into the space continuem? Love this research & how it ties in with they way things are today.

Something to get the Dakar Rally 2024 Live juices flowing. I am joined by Max Sullivan, a renowned mechanic, motor sports journalist, and photographer, who shares his captivating stories from his extraordinary journey, highlighting his role as a technician for maintaining 3 bikes at the the last African Dakar Rally. The conversation explores Max's technical expertise, journalistic skills, and adventurous spirit, offering a glimpse into the world of adrenaline, resilience, and passion.  https://lnkd.in/gPFNmT8F

Charles-Michel Marle (Pierre and Marie Curie University) On Gibbs states built with the moment map of a Hamiltonian action After a short history of Statistical Mechanics, I will recall the definition of a Gibbs state built with the Hamiltonian of a vector field defined on a symplectic manifold. First introduced by the famous American mathematician and physicist Josiah Willard Gibbs (1839--1902), Gibbs states of an isolated mechanical system are statistical states stationary in time, considered by physicists as states of thermodynamic equilibrium. The French mathematician and physicist Jean-Marie Souriau (1922--2012) proposed a generalization of Gibbs states in which the Hamiltonian, which is a moment map of the one-dimensional group of translations in time, is replaced by a moment map of the symplectic action of a general connected Lie group on a symplectic manifold. This moment map (whose existence is assumed) takes its values in the dual of the Lie algebra of the considered Lie group and is equivarian with respect to its action on the symplectic manifold, and an affine action on the dual of its Lie algebra whose linear part is the coadjoint action. In fact, this generalization was already proposed by Gibbs, who shortly considered in his book the product of the one-dimensional group of translations in time and the three-dimensional group of rotations in space. I will present the properties of these generalized Gibbs states, describe the associated generalized thermodynamic functions, in relation with the important notion of entropy. I will discuss several examples, including some cases in which generalized Gibbs states do exist on orbits of some affine actions of the considered Lie group on the dual of its Lie algebra, although no generalized Gibbs state can exist on the coadjoint orbits themselves. https://lnkd.in/eWqpHHte
