Parker Solar Probe : Touch The Sun

Hey friends,
Today we learn a interesting topic 'Parker Solar Probe : Touch the Sun'. In this topic we trying to understand following headings.
  1. What is 'Parker Solar Probe' (PSP)?
  2. How it work?
  3. Instruments used in PSP?
  4. Scientific goals behind this mission
  5. Approaching Records

What is 'Parker Solar Probe' (PSP)

   NASA recently launch a spacecraft named 'Parker Solar Probe'.
  • Launching Date - 12 Aug 2018, 7:31 (GMT)
  • lunching Site - Cape Canaveral SLC-31
  • Launching Vehicle - Delta IV - Heavy with upper stage
Parker Solar Probe is a NASA's robotic spacecraft. Which were previously named Solar Probe (2002), Solar Probe Plus (2010-2017).Finally it named Parker Solar Probe from the name of american scientists Eugene Parker astronomy professor in University of Chicago, Who first discovered the concept of 'Solar Wind' in 1950s.

  • PSP spacecraft is a part of NASA's 'Living with A Star' program. The John Hopkins University Applied Physics Laboratory built this spacecraft and will also operate it. There is a memory card installed in this spacecraft which contains 1.1 millions people names and also contains the photos of Parker and copies of important documents.


How it will work 

   Parker Solar Probe is a 7 years (6 years 321 days) mission.Parker will face extreme high solar radiation approx 650 KW/m² (means 1377°C) at perihelion. Spacecraft system will protect by a solar shield, this is a hexagonal plate with 2.3 m in diameter and 4.5 inch (11.43 cm) thick of reinforced carbon-carbon composite. Its also contain a white reflection alumina surface layer to minimize solar absorption.

While it will take 8 minutes to communicate with earth. Its a fully advanced autonomous spacecraft says by Nicky Fox a project scientist.
   Parker will follow flowing trajectory. In which it moves 24 orbits around the sun. In last 3 orbits its moves to within 3.8 million miles from sun and fly through the birth place of highest energy solar particles. Which is seven time closer than last record.

 It will break all the past record and become fastest moving object in space that ever made by human, its move with 4,30,000 m/h (7,00000 Km/h) speed.

Instruments used in PSP and their uses

   There are some advanced high-tech instruments used in parker which make it a fully advanced spacecraft. Some are given blow in detail.

  • Solar Probe Analyser (SPAN) and Solar Probe Cup (SPC or Faraday Cup) used to investigate the properties of electron, proton, and alpha particles such as density, temperature, velocity etc.
  • Flux-gate magnetometer and Plasma Voltage Sensor used to measure electric and magnetic field, radio waves, electron temperature, poynting flux, and absolute plasma density.
  • EPI-Hi and EPI-Lo used to measure electron proton and heavy particles.
  • Wide field imager used to take images of corona and inner heliosphere.

Scientific goals of Parker

   Behind this mission there are some important scientific goals as follow.

  • Finding the energy that heats the outer surface of sun (corona) and generate the solar wind.
  • To detect how to accelerate and move energetic particle.
  • Define the structure of magnetic field at the source of solar wind.

What is Holography | Basic Principle of Holography | Sci-Talks | Shivam Dhyani

 What is Holography Holography is a technique that enables a wavefront to be recorded and later reconstructed. Holography is best known as a method of generating three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave. Gabor, who invented holography in 1947, introduced the term using two Greek words: “Holos” - whole and “Graphe” - writing. It simply means that the recorded holographic image of the object contains whole optical information about the object – Amplitude and Phase information of the light scattered from the object. Ideally, the hologram is a three-dimensional image reproduced from an interference pattern recorded by coherent light beans and holography is a process of reconstructing and writing a hologram.      White light from the sun or a light bulb is a combination of every color of light in the spectrum, which is not useful for a hologram. However, a laser shine...

How AC (Air Conditioners) Work | Air Conditioning | Refrigeration technology |

Imagine a day of sunny summer and you are walking on the road then you are realize the importance of your AC and say thanks to your AC. Air  conditioner work on interesting technology to keep our room chilled. it use some physical laws of thermodynamics to removing heat from the air inside the room. Air conditioner Photo Credit : coolingcitycenter.in Air Conditioner work efficiently to cool the indoor air quickly, but it consume more electric power to do their job. its work under the basic physical laws which says 'the heat is absorbed during the phase transfer of the refrigerant material. Phase Conversion   : the physical state of the material is changes by absorbing the heat from outside atmosphere by virtue of temperature difference between them. this change in physical state by absorbing heat is called the phase conversation or phase transformation.   Example  :  the piece of ice melt on your palm by absorbing heat from you body, absorbed heat...

Why the Earth revolving around the Sun? And Why the earth also spinning around it's own axis?

Hey friends, Today we learn about another interesting topic about revolving of the earth around sun and spinning around it's own axis. From primary class to higher class we learn that earth revolving around the sun. And spinning around own axis which cause to happening day and night. But you ever thinking why its happen?    In this article we trying to find out the answer of following questions. Why the Earth (or planets) moves around the sun? Is the sun really positioned in the center of solar system? Why the Earth spinning around own axis? When till the Earth spinning? W hy the Earth (or planets) moves around the sun?    Every object in the space is moving continuously with relative to its nearest heavier mass object. Earth is also moves around the sun. There are two famous theories behind this. rotation of earth around the sun *  First according to Isaac Newton the Earth moves around the sun because the higher gravitational force act on ...
