Parker Solar Probe: Mission to Study the Sun

Parker Solar Probe 

Introduction: 

As we need to know that the first ever mission had launched to study the sun at its nearest point that is solar corona (inner side of sun’s atmosphere ).

The mission was launched on 12 August 2018 by delta IV heavy and on 3 October 2018 it fly by venus (moved by gravity assist of venus ) and it had taken the first perihelion round on 5 November 2018.

Objective: The objective of this mission is to unlock the different mysteries of the solar corona and Solar winds. It determined the structure and dynamics of plasma and magnetic field at the source of the solar wind and it also explored what mechanism used that accelerate and transport energetic particles.


Dimensions and System used

How it survive: It is able to survive at the extreme temperature due to a thermal shield that is made up of carbon composite materials that helped to make it unmeltable in extreme temperature (approximately 20 - 25 lakh degrees fahrenheit ) at the solar corona. The cap itself made from seat of Titanium – Zirconium - Molybdenum Which makes it safe. And also there is a system of self cooling that helped to cool internally in extreme temperature.

Trajectory path and the Timeline of this mission 

Timeline: There is a timeline of this mission which state by the space agency NASA. The mission duration is 6 years 11 months. The whole mission have 24 perihelion round and 7 Venus gravity assist fly by.

Timeline is as follow:

  • September 27, 2023: Perihelion round 17
  • December 29, 2023: Perihelion round 18
2024
  • March 30, 2024: Perihelion round 19
  • June 30, 2024: Perihelion round 20
  • September 30, 2024: Perihelion round 21
  • November 6, 2024: Seventh and the Final Venus Flyby
  • December 24, 2024: Perihelion round 22. This round is the First Closest Approach of this mission.
2025
  • March 22, 2025: Perihelion round 23
  • June 19, 2025: Perihelion round 24. This round is the final round and after this it stable there.

After the final round the distance between center of sun and the parker solar probe is 3.38 million miles (5440000 km). And at that time the speed of parker solar probe is 692000 km/h which is 0.064% of speed of light. First time the man made object touches that much speed.

About James Webb Space Telescope

JAMES WEBB SPACE TELESCOPE  JAMES WEBB SPACE TELESCOPE Firstly we need to know about the space telescope. It is a telescope which is placed in outer space and used to observe astronomical objects. And also used to study different types of light phenomenon like Aurora lights and to study hottest and most explosive object. Currently, NASA had launched a space telescope named as JAMES WEBB SPACE TELESCOPE [JWST] . It was made by international collaboration among NASA, the European Space Agency, and the Canadian Space Agency. It works as a replacement of Hubble Space Telescope. JWST was launched on 25 December 2021 on Arian Flight VA256. Firstly it was named as Next Generation Space Telescope and after some time name change to James Webb Space Telescope. There are some properties of JWST are Mass- 6161.4kg , Dimensions- 20.197m×14.162m , Power- 2KW. It operates in a Halo orbit, circling around a point in space known as the Sun-Earth Lagrange Point, approx 1500000km beyond Earth orbit a...

Lifecycle of a star : Birth to Death

STARS AND PLANETS  Star A star is a luminous and biggest object in the universe that emit light naturally. Sun is also a star. The study of birth , life and death of a stars is called stellar evolution. First stage in the birth of star is called protostar and the death of star is called supernova .  FORMATION OF A STAR BY CLOUD OF DUST How stars are formed ? Stars are made by cloud of gases and dust that scattered throughout the galaxies. The cloud of dust is called the orion nebula . As gravitational force of attraction applied on cloud they collapses and when cloud collapse the material at the center get heat up so that all stars and planet have high temperature at core. A star build by continuous process of gravitational pull cloud collapse to make its size bigger. The size of star (or mass of a star) reaches from  15 to 130 solar masses . At center the temperature gets extremely high, it tigger the fusion reaction. All the material that has fallen in then evolves int...

AURORA: THE LIGHT OF POLES

Space view of Aurora Lights  Firstly, we need to know about the aurora. Auroras are the light which is produced naturally by collision of charge particles with gasses molecules present in the atmosphere. Predominantly sun in high latitude region like arctic and Antarctic. This light produces always at poles because magnetic field of earth is stronger on the poles and also the density of magnetic field lines is high there. Thus, a large number of charge particles found at the poles. The charge particles collide with the gasses to making them excited that cause  coloured visible light. When the charge particle collides with oxygen molecules then green light is emitted mostly but sometimes it produce red light and when collides with nitrogen molecules then more pink , orange or red colours emitted. Different types of Aurora Light seen on different places  These light appearing near the North Pole and South Pole. Scientist name these light as at North Pole light called “ A...
