Question: Magnetospheric Multiscale mission (MMS) of NASA has recently taken 1st high-resolution measurements of an interplanetary shock event originated in the?
- Magnetospheric Multiscale mission (MMS) has obtained 1st high-resolution measurements of an interplanetary shock event. The MMS mission measured the shock with fast and high-resolution instruments including the Fast Plasma Investigation (FPI).
- The findings have been published, in August 2019, in the Journal of Geophysical Research: Space Physics.
- FPI can measure ions and electrons around the spacecraft at up to 6 times per second.
- It should be noted that these shocks are originated from the Sun which continually releases streams of charged particles called the solar wind.
- According to the researchers Solar winds are of two types, slow and fast. When a fast stream of solar wind overtakes a slower stream, it creates a shock wave.
- These shocks are not only the phenomenon found on the Sun but in every part of the Universe, including in supernovae, black holes, and distant stars.
- It occurs when particles transfer energy through electromagnetic fields instead of directly bouncing into one another.
- The advantage is that these shocks provide ideal situation for understanding about larger universal phenomena.
Magnetospheric Multiscale Mission (MMS):-
- In March 2015 to study Earth’s magnetosphere US space agency NASA launched robotic space mission known by the name Magnetospheric Multiscale mission (MMS) .
- MMS comprises of 4 identical spacecraft, which fly in a tight formation that allows for the 3D (3-Dimensional) mapping of space.
