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.

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

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.
