We routinely simulate the universe on all of its scales, from planets to large fractions of the cosmos. Today we’re going to see how it’s possible to build a universe in a computer – and see whether there’s a limit to what we can simulate.

Why don’t rocket engines melt? How engineers keep engines cool

Why don’t rocket engines melt? How engineers keep engines cool

Rocket engines need to produce heat to function, after all, their only real purpose is to convert the chemical energy in the propellant into pressure and heat so they can produce thrust.

And that brings up an obvious question! How in the heck do engines survive this heat? How did rocket scientists figure out how to keep an engine running continuously while harboring combustion inside it that’s hot enough to melt the very walls that are containing it?!

Today we’re going to talk about the tricks engineers employ to keep rocket engines from melting. We’ll go over ablative cooling, regenerative cooling, film cooling, radiative cooling, heat sinks, and fuel to oxidizer ratios and show you some awesome examples of each.

Here’s an article version of this video – https://everydayastronaut.com/engine-cooling-methodes/

Transporter-3 Mission

Transporter-3 Mission

SpaceX is targeting Thursday, January 13 for a Falcon 9 launch of Transporter-3 to orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The 29-minute launch window opens at 10:25 a.m. EST, or 15:25 UTC, and a backup opportunity is available on Friday, January 14 with the same window.

Falcon 9’s first stage booster previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.

Transporter-3 is SpaceX’s third dedicated rideshare mission, and on board this launch are 105 spacecraft (including CubeSats, microsats, PocketQubes, and orbital transfer vehicles).

If you used every particle in the observable universe to do a full quantum simulation, how big would that simulation be? At best a large molecule. That’s how insanely information dense the quantum wavefunction really is. And yet we routinely simulate systems with thousands, even millions of particles. How? By cheating. Using the ultimate compression algorithm: Density Functional Theory (DFT). Let’s learn how to cheat the universe.

News Update on James Webb Space Telescope’s Full Deployment

Experts from the James Webb Space Telescope team discuss the successful completion of the final stage of all major spacecraft deployments to prepare for science operations.

On Sat., Jan. 8, Mission Operations Center ground control at the Space Telescope Science Institute in Baltimore began deploying the second side panel of the primary mirror at 8:53 a.m. EST. Once it extended and latched into position at 1:17 p.m. EST, the team declared all major deployments completed.

I asked you to predict 2021’s spaceflight milestones…

On January 1st, 2021, I tweeted a set of polls and wanted to see how well we in the spaceflight community could predict what would happen in the year forward. Well… it was… interesting…

Did you take this poll? Click here and follow along to see how you did! https://twitter.com/Erdayastronaut/status/1345088942492811266
