Most spacecraft & satellites, whether they are orbiting Earth at an altitude of a few hundred miles, or exploring Saturn 886 million miles away, will always enter a specific type…
In 2016, a Falcon 9 rocket unexpectedly exploded on the launchpad due to a breach in the helium system used to pressurize the propellant tanks, which raised the question of…
When watching a rocket launch, you may have heard the callout “Engine chill has started,” which forms part of a long list of prelaunch procedures during an orbital launch event….
When discussing liquid rocket propellants, one often thinks of RP-1, liquid hydrogen, or methane. But another liquid propellant known as hypergolic fuel has been used for decades in spaceflight due…
During the late 20th Century, rockets were largely considered expendable. But since the turn of the Century, as private space launch providers started entering the arena, the importance of cost…
Most orbital rockets, from the Saturn V carrying astronauts to the Moon in the 1960s to a modern Falcon 9 or Ariane 5 launch vehicle, are primarily covered in white….
Most liquid rocket propellants like hydrogen, methane & liquid oxygen are cryogenic, meaning they have to be stored at subzero temperatures to remain in a liquid state. This poses a…
Frequent viewers of orbital rocket launches may have noticed that the hot exhaust plumes generated by the launch vehicle on the launchpad expand horizontally before billowing up into the air….
Regular viewers of rocket launches streamed online by companies like SpaceX and Rocket Lab may have seen two objects falling away from the rocket shortly after second-stage ignition. They are…
