Khorramshahr- 4 Ballistic Missile


  •     Prelims: Science and Technology

Context: Iran unveiled a new Liquid-Fuel Ballistic Missile named “Khorramshahr-4” with a range of 2,000 Kilometers.

About Khorramshahr-4 Ballistic Missile:

  • The Khorramshahr has the heaviest payload of Iran’s ballistic missile fleet.
  • The Khorramshahr-4 is named after an Iranian city that was the scene of heavy fighting during theIran-Iraq War in the 1980s.
  • Khorramshahr-4 Missile has a 2,000-kilometre range and can carry 1,500-kilogram warhead.
  • The Khorramshahr-4 missile has a navigational aid system and can transport a large warhead.
  • According to official accounts, the enemy’s defense systems cannot detect, intercept, or take action to destroy the warhead due to its fast speed when it strikes the target.
  • This missile is the most recent iteration of the Khorramshahr family of point-blank missiles, which do not require final-stage guidance.
  • The ability to target precisely when in mid-flight (above the atmosphere) distinguishes this missile from its earlier iterations.

X-Ray Polarimeter Satellite (XPoSat)


  •     Prelims: Science and Technology

Context: The Indian Space Research Organization (ISRO) is collaborating with the Raman Research Institute (RRI), Bengaluru, to build the X-Ray Polarimeter Satellite (XPoSat) that is scheduled to be launched later this year.

About X-Ray Polarimeter Satellite (XPoSat):

  • According toISRO, “XPoSat will study various dynamics of bright astronomical X-ray sources in extreme conditions.”
  • The spacecraft will carry two scientific payloads in a low earth orbit.
  • The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization).
  • POLIX is expected to observe about 40 bright astronomical sources of different categories during the planned lifetime of XPoSat mission of about 5 years.
  • This is the first payload in the medium X-ray energy band dedicated for polarimetry measurements.
  • The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information on how light is absorbed and emitted by objects. It would observe several types of sources, such as X-ray pulsars, black hole binaries, low-magnetic field neutron star, etc.
  • X-Ray Polarimeter Satellite (XPoSat) is India’s first, and only the world’s second polarimetry mission that is meant to study various dynamics of bright astronomical X-ray sources in extreme conditions.
  • The other such major mission is NASA’s Imaging X-ray Polarimetry Explorer (IXPE) that was launched in 2021.
  • IXPE carries three state-of-the-art space telescopes.
  • Each of the three identical telescopes hosts one light-weight X-ray mirror and one detector unit.
  • These will help observe polarized X-rays from neutron stars and super massive black holes.
  • By measuring the polarisation of these X-rays, we can study where the light came from and understand the geometry and inner workings of the light source.
