TESS Mission

  • The Transiting Exoplanet Survey Satellite (TESS) is an MIT-led NASA’s mission.
  • It is to spend two years discovering transiting exoplanets by an all-sky survey.
  • The primary goal of TESS is to discover planets smaller than Neptune.
  • With TESS, it is possible to study the mass, size, density and orbit of a large cohort of small planets.

Mission Shakti

  • It was India’s successful ‘Anti-satellite (ASAT) missile’ test.
  • An Indian satellite at 300 km in Low Earth Orbit was targeted and destroyed through ‘collision’ (rather than warheads).
  • It made India to join the ranks of the US, Russia and China.
  • It gives teeth to India’s space programme and military posture.
  • It was the prerogative of DRDO.
  • The DRDO’s Ballistic Missile Defence interceptor was used.
  • A BMD, by destroying incoming missiles, provides a strategic umbrella,
  • ASAT adopted ‘Direct Ascent Kinetic Kill’ method.

India & Outer Space

  • India has no intention of entering into an arms race in outer space.
  • India believes that Outer space is the common heritage of humankind and it is the responsibility of all to preserve it.
  • India already implements a number of Transparency and Confidence Building Measures(TCBMs) includes,

  2. Pre-launch notifications,
  3. Measures in harmony with the UN Space Mitigation Guidelines,
  4. Participation in Inter Agency Space Debris Coordination (IADC) activities with regard to space debris management,
  5. Undertaking SOPA (Space Object Proximity Awareness) and COLA (Collision Avoidance)
  6. Participating in all sessions of the UN Committee on the Peaceful Uses of Outer Space.
  • India also supported UNGA resolution 69/32 on ‘No First Placement of Weapons on Outer Space’.
  • India supports the substantive consideration of the issue of ‘Prevention of an Arms Race in Outer Space’ (PAROS).
  • India is a signatory to 1967 Outer Space treaty.
  • It prohibits only weapons of mass destruction in outer space, not ordinary weapons.
