CAPE CANAVERAL — Bright winter flowers bloom amid the weeds around an unsettling concrete and steel hulk that marks one of the darkest days in American space history – the Apollo 1 command module was destroyed by fire during a launch rehearsal test on Jan 27, 1967, marking one of America’s darkest moments in space…
Docking spacecraft can be an intricate and dangerous procedure. Both the International Space Station (ISS) and any visiting shuttle or capsule orbit the Earth at high speeds, making small corrections easy enough to send both rocketing away. Both US and Russian segments of the station feature systems to reestablish communication; these IDA ports (Induced Degradation…
Color is more than simply one hue; understanding their interactions is crucial for creating presentations and selecting a color palette for projects. Tyndall and Rayleigh believed that the blue color of the sky must be due to microscopic particles of dust or droplets of water vapour in the atmosphere. Blue Light Light from the sun…

It is thought that the term ‘Arctic’ derives from Greek word Arktos, meaning bear. This may have originally referred to constellations Ursa Major (Great…
Spacecraft propulsion systems employ fuel and oxidizer to alter vehicle momentum. Their effectiveness can often be gauged by their specific impulse – which measures how much thrust they produce per mass flow rate rate per second. Newton’s Law holds that for every action there is an equal and opposite reaction; however, you cannot use force…
Northern Sky has long been a fan-favorite from Nick Drake. Its lyrics seem to depict an emotional release for Drake while also touching on spiritual themes such as fate and karma.

Spacecraft attitude dynamics and control is a study that encompasses kinematics, rigid-body dynamics, linear control theory and orbital environmental effects. This block models attitude dynamics using numerical integration. Spacecraft use thrusters to propel themselves in specific directions, however this approach has its limitations, including fuel usage and thruster cycle time. An alternative would be relying…
