Expected Questions on Space Research: UPSC IAS 2017

Dr. Manishika Jain in this video covers a variety of topics which are important for 2017. These include the expected questions on space research.

Kepler-1649

  • Kepler space telescope disc. Venus like planet
  • 1/5th diameter of sun
  • 219 light years away from Earth
  • Insight into the nature of planets encircling around M dwarf stars
  • Kepler space telescope – unmanned space observatory in 2009 by NASA

Sentinel-2B

  • 5th of Sentinel Earth observation satellite
  • Will join Sentinel 2-A which was in orbit since 2015
  • Part of multimillion Copernicus observation program (World’s largest single earth observation program)
  • Copernicus observation program is successor of European Envisat program (2002 to 2012)

7 New Earth Sized Exoplanets

  • These orbit dwarf planet Trappist-1
  • Detected by NASA’s Spitzer Space Telescope
  • TRAPPIST-1 e, f and g in habitable (Goldilocks zone)
  • Exoplanets do not orbit sun but any star

Massive Planet orbiting X-Ray Binary Star

  • MXB 1658 - 298 is an X-ray binary
  • Part of constellation Ophiuchus (serpent bearer)
  • X-ray binaries consist of a pair of stars orbiting each other of which one is compact one such as a black hole or a neutron star.
  • In X-ray binaries, time in-between eclipses of source can increase, decrease and also shows abrupt changes
  • In MXB 1658 - 298: time between eclipses increases and decreases periodically

Mission to Study Neutron Star

  • By NASA
  • Neutron Star Interior Composition Explorer, or NICER, aboard a Falcon 9 rocket.
  • Will focus on Pulsars (remnant of massive star)
  • 1st demonstration of X-ray Navigation in space
  • Insight of structure and starquakes

KELT-9b

  • Hottest exoplanet in universe
  • Published in Journal Nature
  • Temperature 4236℃
  • 650 light years from Earth
  • 2.8 times massive than Jupiter

World’s largest Telescope in Chile

  • Extremely Large Telescope (ELT)
  • 5 times larger than the existing
  • 3000 mt high in Atacama desert
  • Cost – 1 billion euro in 2012
  • Main mirror to measure 39 mt across
  • By European Southern Observatory

Earth Sized Storms on Jupiter

  • Discovered by NASA Juno Spacecraft
  • Jupiter has strong magnetic field – 7.66 Gauss (10 times stronger than Earth)
  • Juno – 1st solar powered spacecraft to orbit Jupiter (2nd after Galileo) – completed 4th closest flyby of Jupiter

Lunar Like Environment on Earth

  • Simulated by China laboratory
  • Yuegong -1 or Lunar Palace
  • World’s most advanced closed loop life supporting technology
  • World’s third bioregenerative life support base
  • 2014: ‘Moon Palace 1’, a 160m2 self-contained laboratory to prepare placing astronauts in outer space for extended periods of time.

Sounding Rocket to Release Radiant Artificial Cloud

  • Terrier-Improved Malemute sounding rocket into the space that will release blue-green and red artificial clouds.
  • Rocket will eject vapour canisters between 10 to 20 km
  • Vapour tracers will be formed due to the interaction of barium, strontium and cupric-oxide
  • Help to study ionosphere
  • To study wind and earth’s magnetic field

HAT-P-26b

  • Water traces discovered
  • By Hubble & Spitzer telescope
  • Made of hydrogen and helium
  • Published in Journal Science
  • 437 light years away
  • Planet metallicity is 4.8 times that of Sun

Cassini Spacecraft

  • Started 22 orbits
  • Plunge into Saturn on 15 Sept 2017
  • Complete 20 years journey
  • Was launched in 1997
  • Jointly by NASA, European Space Agency (ESA) and Italian space agency, Agenzia Spaziale Italiana (ASI).
  • 4th space probe to visit Saturn & 1st to enter its orbit
  • Has probe Huygens for Saturn’s moon

Tiangong-2

  • Cargo spacecraft Tianzhou-1 with Toangong-2 space lab
  • Establish permanently manned space station by China in 2022, in orbit for 10 years
  • Carry 6 tons of goods, 2 tons of fuel and can fly unmanned for three months.

Parker Solar Probe

  • By NASA
  • Will be launched in 2018
  • Study sun’s outer atmosphere & how sun works
  • Named after Astrophysicist Eugene Parker (gave solar winds idea in 1958) – 1st time named after living person
  • Study structure and dynamics of plasma and magnetic fields at solar wind source
  • NASA’s first mission to the sun and its outermost atmosphere corona
  • Scheduled to end in June 2025
  • Made of Advanced carbon composite material – allows instruments to operate at room temperature

ADITYA L1

  • India’s first solar mission
  • Will study Sun’s outermost layers: Photosphere, Chromosphere and Corona
  • Joint Venture: ISRO and physicists from other institutes of India
  • Will be Placed: Halo Orbit around Lagrangian point 1 (L1) of Sun-Earth System (L1 lies on the direct line between Earth & Sun)
  • Will collect data on Coronal mass ejection & Space weather prediction
  • Will be launched in 2019 - 20 by PSLV
