Space Science’s Unsung Heroes, part 2

There are many people who may not be that popular as many astronauts but their work has been a guiding light for the further development of space science.

John C. Houbolt at blackboard, showing his space rendezvous concept for lunar landings. Although Houbolt did not invent the idea of LOR, he was the person most responsible for pushing it at NASA.

Ion Thrusters: How it works?

Ion Thrusters shoot Electrons over the atoms of an inert gas and knock off more electrons from it, there by creating positive ions.

Cold Gas Thrusters: How it works?

A cold gas thruster is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust.

Phosphine is shaped like a pyramid with three atoms of hydrogen bonded to a single atom of phosphorus.

Is Life on Venus Possible?

Recently, British scientists revealed they had uncovered strong evidence that phosphine – a toxic, rancid gas produced by microbes – exists in the burning, acid-drenched atmosphere of Venus.

Vernier Engines — What is it?

A vernier thruster is a rocket engine used on a spacecraft for fine adjustments to the attitude or velocity of a spacecraft. The name is derived from vernier calipers (named after Pierre Vernier).

Raptor Engine: Layman Explanation

What is meant by "Full-flow staged combustion cycle" — the one that mighty Raptor Engine has got. The idea of this article is to give you a complete layman's explanation.

ISS: Assembling the Big Lab

The process of assembling the International Space Station (ISS) has been under way since the 1990s. Zarya, the first ISS module, was launched by a Proton rocket on 20 November 1998.

ISS: How such a big thing was made?

The manufacturing of ISS took a modular approach where different countries and space organisation taking the lead and control in design and manufacturing of each modules, which were ~40 in count.
