Children are naturally curious about their world. A question often raised is: Why is the sky blue? Light is scattered as it travels through the atmosphere by air molecules; blue wavelengths tend to be more strongly scattered. The Sun’s Light The Sun emits light over an array of wavelengths (or colors). Our eyes, however, perceive…
Apollo 10’s crew made history, yet their mission was only meant as a dress rehearsal for Neil Armstrong and Buzz Aldrin’s epic landing on Apollo 11. While astronaut John Young remained in his command module, Stafford and Cernan disembarked from the Lunar Module (LM) and descended to just above the Moon. It was a dress…

Spacecraft parts refer to all components of spaceships or robots designed to travel beyond Earth’s atmosphere and explore outer space, such as satellites orbiting Earth, rovers sent out to other planets, or Apollo capsules that carried astronauts between Earth and the Moon. Spacecraft systems include multiple subsystems that vary based on mission requirements. These may…
At night, the sky is dark blue due to atmospheric scattering of sunlight. Blue light scatters more readily than red light due to shorter wavelengths being more easily diffused into space. Answer is straightforward physics: as the Sun gets lower in the sky, more of its light passes through your atmosphere to reach you –…
The spacecraft bus serves as the primary system that supports all other spacecraft hardware. Designed to accomodate various mission specific payloads with high reliability, this structure supports all other spacecraft hardware. MagicBus platform currently enjoys flight heritage on several small satellite missions and has demonstrated multi-mission adaptability. Its modular design features lower part count and…
Propulsion systems are usually the most complicated and expensive components of spacecraft. To maximize its potential, it is crucial that we understand their capabilities. This survey foregoes direct technology maturity assessments (TMAs) using NASA’s TRL scale, acknowledging its complexity is challenging to perform accurately without sufficient in-depth technical insight into individual devices. Chemical Chemical spacecraft…
