Ion Thrusters – What They Are And How They Work
With so much focus on rocket fuels like hydrogen and new alternatives like liquid methane, it is hard to believe that an advanced form of propulsion known as ion thrusters…

Satellites and spacecraft, whether orbiting Earth at altitudes of a few hundred miles or exploring Saturn 886 million miles away, will always enter an orbit around a celestial body at…
A Falcon 9 rocket unexpectedly exploded in 2016 on the launchpad due to a failure in the helium system used to pressurize the propellant tanks, which raised the question of…
While watching a rocket launch, you may have heard the callout “Engine chill has started,” which forms a crucial part of the prelaunch procedures during an orbital launch event. We…
When discussing liquid rocket fuels, one primarily thinks of RP-1, liquid hydrogen, or methane. But another liquid propellant known as hypergolic fuel has been used for decades in spaceflight due…
In the late 20th Century, rockets were largely considered expendable. However, as private space launch providers started entering the industry at the start of this Century, the importance of reusability…
Most orbital rockets, from the Saturn V carrying astronauts to the Lunar surface in the 1960s to a modern Falcon 9 or Ariane 5, are primarily covered in white. This…
The majority of liquid rocket propellants like hydrogen, methane, and liquid oxygen are cryogenic since they are stored at subzero temperatures to stay in a liquid state. It poses a…
Frequent viewers of rocket launches will have noticed the white plumes of “smoke” generated by the rocket’s boosters expanding horizontally away from the launchpad before billowing up. It’s a result…
Regular viewers of rocket launches streamed online by companies like SpaceX and ULA might have seen two objects falling away from the rocket shortly after second-stage ignition. They are known…
