Heat Shield Color Changing Mug
$24.99
FEATURES Heat-sensitive mug reveals heat shield design when hot. Exposure to reentry plasma NOT recommended PRODUCT SPECS Size: 8 cm x 9.5 cm [3.15" x 3.74"] 11oz Material: Ceramic Hand wash only Not microwave safe
Grid Fin Button Up L
$54.99
SpaceX's Falcon 9 rocket is capable of landing its first stage booster in order to be recovered and reused. It employs a handful of unique techniques and specialized hardware to accomplish this once thought impossible feat. Perhaps one of the most iconic bits of hardware are the four grid fins that are attached near the top of the booster on the interstage. These grifdins provide steering authority while the booster is back in the atmosphere after falling from space. They help guide and steer the booster to its landing target, either an autonomous spaceport drone ship, or the a landing zone nearby the launch pad. PRODUCT SPECS 100% Cotton Slim Fit [size chart] CARE INSTRUCTION Hand wash separately in cold water. Do not machine wash. Do not bleach. Line dry.
Hydrazine Mug
$15.99
Hydrazine (N2H4) is a highly reactive and potent chemical compound commonly used as a fuel for rockets and more commonly spacecraft. It's a common fuel choice for hypergolic systems, often paired with Dinitrogen Tetroxide. This hypergolic property makes it highly reliable and responsive for control thrusters, which is crucial for delicate operations like satellite positioning or orbital adjustments. However, it's highly toxic and corrosive, requiring strict handling and storage procedures to ensure safety. FEATURES Not recommended for storing Hydrazine PRODUCT SPECS [8.5 oz - 250 ml] Glass Mug Hand washing only
Methalox Tee L
$39.99
PRODUCT SPECS Designed with a high-ribbed collar that provides a snug, comfortable fit that will not stretch out or lose its shape over time. Cut with a spacious fit in the sleeves and torso, making it relaxed and versatile enough to wear with anything. Made of 100% USA cotton Durable, comfortable, and virtually shrink-free thanks to the garment dye process. broken-in feel, just like your favorite T-shirt that's been worn for a decade. Knitted, cut, sewn, and dyed in Los Angeles, California.
Methalox Hoodie L
$79.99
PRODUCT SPECS Fit: Oversized-fit, DON'T need to size up 80% Combed Cotton / 20% Polyester French Terry No Draw Cords Raglan drop shoulder sleeves
Hypergolic Tee L
$39.99
Hypergolic propellants, when combined, ignite spontaneously upon contact, without requiring an external ignition source like a spark or flame. While this characteristic enhances reliability and simplifies liquid-fueled rocket engine designs, it is imperative to note that hypergols are extremely toxic and corrosive. Handling and storage require careful attention and demanding safety measures PRODUCT SPECS Garment dyed for that lived in feel and almost no shrinkage at home Soft ring spun cotton fabric with 100% cotton threads Topstitched, classic width, rib collar

00:00 - Intro 02:55 - Basic physics of rocket engines 06:10 - Rocket engine cycles 20:30 - Rocket fuel comparison 30:40 - Raptor vs other rocket engines 44:05 - Summary Article version - https://everydayastronaut.com/?p=9823... SpaceX's new raptor engine is a methane fueled full flow staged combustion cycle engine and its so hard to develop, no engine like this has ever flown before! Now this topic can be really intimidating so in order to bring the Raptor engine into context, we’re going to do an overview of a few common types of rocket engine cycles then compare the Raptor to a few other common rocket engines, like SpaceX’s current work horse, the Merlin, The Space Shuttle’s RS-25, the RD-180, Blue Origin’s BE-4 and the F-1 engine. And if that’s not enough, not only is SpaceX using a crazy engine cycle, they’re also going to be using Liquid Methane as their fuel, again something that no orbital rocket has ever used! So we’ll also go over the unique characteristics of liquid methane as a rocket fuel and see if we can figure out why SpaceX went with Methane for the Raptor engine. We'll also break down and explain all the different engine cycle types so you know what the full flow staged combustion cycle is, how it works, and how it compares to the other cycles. So by the end of this video hopefully we’ll have the context to know why the raptor engine is special, how it compares to other rocket engines, why it’s using methane and hopefully find out if the Raptor engine will be the new king of rocket engines… ----------------------------------------------- Rocket engine renders by @MartianDays   / martiandays   F-1 Turbopump photo provided by Mike Jetzer/heroicrelics.org HUGE thanks to my Moon Walker Patreon supporters!
