South Atlantic Anomaly (SAA)
It is the near-Earth region where the Earth's magnetic field is weakest relative to an idealized Earth-centered dipole field.
It is an area where the Earth's inner Van Allen Radiation Belt comes closest to the Earth's surface, dipping down to an altitude of 200 KM.
This leads to an increased flux of energetic particles in this region and exposes orbiting satellites to higher-than-usual levels of radiation.
The effect is caused by the non-concentricity of the Earth and its magnetic dipole.

Air Breathing Engine
- It uses oxygen from the atmosphere in the combustion of fuel.
- They include the turbojet, turboprop, ramjet, and pulse-jet.
- This system is lighter, efficient and cost-effective than other systems in use.
Types of Air Breathing engines
Ramjet:
- uses the vehicle’s forward motion to compress incoming air for combustion without a rotating compressor.
- work most efficiently at supersonic speeds but not at hypersonic speeds.
Scramjet
- It is an improvement over the ramjet engine as it efficiently operates at hypersonic speeds and allows supersonic combustion.
Dual Mode Ramjet (DMRJ)
- It is a type of jet engine where a ramjet transforms into a scramjet over Mach 4-8 range.
- It can efficiently operate both in subsonic and supersonic combustion modes.

Vitamin D
- It is a fat-soluble vitamin, meaning that it dissolves in fats and oils and can be stored in your body for a long time.
- It is produced when sunlight (or artificial light, particularly in the ultraviolet region of 190-400 nm wavelength) falls on the skin and triggers a chemical reaction to a cholesterol-based molecule, and converts it into calcidiol in the liver and into calcitriol in the kidney.
