📬 A Double Threat: Moscow's Coup Attempt and U.S. Dollar Recall

We are witnessing a period of profound global instability. [USA Insider News]( Dear Reader, We are witnessing a period of profound global instability. The shocking military coup attempt in Moscow has left the world teetering on the brink of chaos, drawing stark comparisons to Russia's infamous 1917 "civil war". This unrest, coupled with the U.S. government's imminent plan to recall the dollar as soon as July 26, could significantly disrupt our financial systems. In this global turmoil, your savings could be at risk - especially if they are in U.S. dollars. More so, if [your bank is among the recently 'blacklisted' 110 U.S. banks](. The combination of Russian unrest and the impending dollar recall may have far-reaching consequences for your financial security. Don't let the crises of the world catch you off-guard.

PLIF is a laser-based imaging technology used to create a picture of the flow field around a vehicle. The PLIF technique uses a planar laser light sheet to excite molecules of seeded nitric oxide (NO) in the air flow around the test model and induce ultraviolet fluorescence. The paths of the excited molecules are tracked using a special camera that intensifies ultraviolet light to form a picture of the flow patterns around the vehicle. The PLIF measurements are also processed to provide temperature and velocity data in the flow field. PLIF data sets can be used for comparisons with computational flow field simulations in order to assess the accuracy of the numerical tools that NASA employs in the design of hypersonic entry vehicles such as LOFTID, which is the vehicle configuration being used in this test program. LOFTID research laser science NASA heat shield Olivia Tyrrell and Neil Rodrigues prepare the laser set-up for their experiment to capture imagery of the wake flow behind a model of NASA’s LOFTID vehicle. Credits: NASA The LOFTID flight test was designed to address technical challenges in the development of inflatable heat shield technologies for eventual use in operational NASA and commercial missions. Among these are understanding the nature of the wake flow behind the inflatable aeroshell. The wake flow is characterized by complex, unsteady patterns of rotating vortices, which are challenging to simulate using computational methods. Data collected during the flight test helped to validate the performance of those models, as did the data collected with PLIF on the LOFTID model used in this wind tunnel test. “Wake flow is challenging to model,” said Neil Rodrigues, principal investigator for the test series. “With these tests we want to see if we can match the data from previous simulations and the flight test. That will help give us more insight on what’s happening in flight and can help improve the design to scale up the technology and improve the modelling. More modelling equals less risk and potential to save on cost and weight.” This wind tunnel test entry was jointly supported by the LOFTID mission, which has direct use for the data, and the Entry Systems Modelling (ESM) project, which sponsors research and development on computational methods for high-speed flight problems.
