x-ray polarimeter satellite (xposat) mission
The XPoSat, or X-Ray Polarimeter Satellite, is a significant milestone in India’s space exploration efforts. This article provides an in-depth look at XPoSat, its mission, significance, and related discoveries.
XPoSat Full Form
XPoSat stands for X-Ray Polarimeter Satellite.
XPoSat Mission
Purpose of XPoSat
The principle scientific mission of XPoSat is to map the polarization of Cosmic X-rays. Studies have also shown that by analysing the polarization, astronomers can get to learn characteristics and behavior of X-ray sources in the universe such as black holes, neutron stars, and pulsars among others.
XPoSat Satellite
The instrument XPoSat will be observing and measuring the polarization of x-ray from various sources in space. This satellite shall aid the researchers to investigate the composition and characteristics of these high-energy sources in the universe since they are significant for analyzing the energetic events and structures.
XPoSat Built By
Currently, XPoSat is in the developmental stages by the Indian Space Research Organisation (ISRO) along with researchers from other institutions. It also does make the satellite symbolize an advancement for India in the fields of space technology and scientific research.
XPoSat Cost
The estimated cost of the XPoSat mission is approximately $30 million. This investment underscores India’s commitment to advancing space science and contributing to global astronomical research.
What is Polarisation of X-Ray Sources?
Polarization of X-ray sources refers to the orientation and alignment of X-ray waves emitted by celestial objects. By studying the polarization, scientists can infer the physical properties, magnetic fields, and environments of these X-ray sources. This data is essential for understanding the extreme conditions and processes occurring in the universe.
X-Ray Polarimeter Satellite (XPoSat) Mission
The XPoSat mission aims to be India’s first dedicated X-ray polarimetry mission. The satellite will carry instruments designed to measure the polarization of X-rays from various cosmic sources. This mission will provide valuable data to enhance our understanding of high-energy astrophysical phenomena.
Significance of XPoSat
XPoSat’s significance lies in its potential to provide groundbreaking insights into the universe’s most energetic and mysterious phenomena. By measuring the polarization of X-rays, XPoSat will contribute to:
- Understanding Black Holes: Providing data on the magnetic fields and environments around black holes.
- Studying Neutron Stars: Offering insights into the structure and behavior of neutron stars and pulsars.
- Advancing Astrophysics: Enhancing our knowledge of high-energy astrophysical processes and contributing to the global scientific community.
Launch Vehicles
XPoSat will be put into orbit by one of the sounding rockets that India’s space research organization ISRO has successfully developed. Information regarding the actual vessel to be used in this mission, is yet to be announced; however, PSLV or GSLV , both belonging to ISRO, constitute probable choices because of their reliability.
Related Discoveries: Six New Exoplanets
What is an Exoplanet?
An exoplanet is defined as a planet that moves around a star not in the solar system. They can be relatively large or small, made of solids or gases, or situated close or far from their host stars, and that makes them attractive to astronomers.
Discovery of Six New Exoplanets
Recently, six new exoplanets have been identified with the information about other planetary systems other than the familiar solar system. These discoveries are important as they shed light on the formation and evolution of planets in the solar system as well as their habitability.
Physical Characteristics of Exoplanets
Its recommended that exoplanets be classified by type, such as gas giants, rocky planets, and those with peculiar atmospheres. These include the relative size, mass density, and location orbit of the planet in relation to their formation and ability to host life.
TESS (Transiting Exoplanet Survey Satellite)
TESS is a NASA mission designed to search for exoplanets using the transit method. It monitors the brightness of stars and looks for periodic dips in brightness, which indicate a planet passing in front of the star.
How Does TESS Find Planets?
TESS finds planets by detecting the slight dimming of a star’s light caused by a planet transiting, or passing in front of, the star. This method allows scientists to determine the planet’s size, orbit, and other key characteristics.
India’s Efforts to Discover Exoplanets
India has also been actively involved in the search for exoplanets. ISRO and Indian scientists contribute to global efforts through observations, data analysis, and participation in international collaborations.
