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.

SONAR DOME

  • First of its kind in India has been manufactured
  • Designed by Research and Development Establishment (Engineers), DRDO laboratory in Pune
  • Manufactured by Goa-based composites manufacturing company Kineco
  • Technology used Vacuum Assisted Resin Transfer Molding (VARTM)
  • Sonar (Sound navigation and ranging): Detect objects under water by emitting sound pulses and measure their return after being reflected
  • Uses bouncing acoustic waves of objects, and determine their distances by measuring the time for return echoes.
  • Used on board ships and boats to measure depths of water bodies, to locate underwater objects such as fish, submarines & shipwrecks.

PROVe

  • Indigenously-developed Remotely Operated Vehicle
  • To map the coral reefs in Andaman & Nicobar Islands (hot-spots of biodiversity)
  • Developed by National Institute of Ocean Technology
  • Can map 4 - 6 sq. km per day
  • Coral reef biodiversity at Andaman region, roughly around 11, 000 sq. km
  • Stress from the increasing sea surface temperature

PLANET 9

Image of Planet Nine

  • Discovery of exoplanet or extra solar planet inside the solar system
  • Exoplanet: A planet located outside our solar system
  • What happened? -Sun, in its youth some 4.5 billion years ago, stole Planet Nine from its original star

Space-Based Telescopes for Actionable Refinement of Ephemeris (STARE) Mission

SpaceBased Telescope Actionable Refinement of Ephemeris Mission

SpaceBased Telescope Actionable Refinement of Ephemeris Mission

  • Help satellite operators prevent collisions in Low Earth Orbit (LEO)
  • Pathfinder mission for a constellation of satellites
  • “Space traffic cams” will lower false collision warnings, allow satellite operators to take action when in danger.
  • Reduce uncertainty of 1 km to 100 or less to avoid and reduce number of collision of satellites and space debris.

Kirameki-2

  • 1st military communication satellite
  • On board of H2A rocket
  • Upgrade communication network
  • Check maritime activity & N. Korea missile threat

TanSat

  • By China
  • Monitor carbon dioxide
  • Launched on March 2-D rocket
  • 3rd Nation after Japan & USA to have GHG monitoring satellite
  • Monitor levels every 16 days

Falcon 9 Rocket

  • Launches 10 satellites in orbit, part of McLean, Virginia-based Iridium’s project to replace its existing network of satellites that provide global voice and data communication
  • By company SpaceX – 1st privately funded company to successfully launch, orbit and recover a spacecraft (Dragon) in 2010

Explore Iron Rich Asteroid 16 Psyche

  • Approved by NASA
  • Launched in 2023 and will reach in 2030
  • Mineral contents are worth over 100-thousand times value of the entire world economy
  • Diameter in excess of 125 miles & entirely made of iron and nickel
  • Protoplanet i. e. its entire body is of what one day could be the core of a new planet
  • Can have water – to be used for stellar fuel station, to sustain life and synthesize rocket fuel.

Vela Super Cluster

  • Universe’s biggest galaxy supercluster
  • Carry 1 lakh galaxies with trillions of stars

103 Satellites in One Launch

  • By PSLV (C37)
  • In 2014 by Russia – 37 satellites
  • In 2013 – NASA – 29 satellites
  • In 2016 – ISRO – 20 satellites
  • Separated satellites will have relative velocity of 1 m/s
  • 1st satellite launched will move at relatively faster velocity than the next satellite.

GSLV Mk III D1

  • 4 ton class of satellite into GTO (Geosynchronous Transfer Orbit) & 8 ton in LEO (Low Earth orbit)
  • Heaviest rocket
  • Next generation launch vehicle
  • Game changer vehicle
  • Payload: GSLV 19
  • GSLV-19: Ka and Ku band payload with Geostationary Radiation Spectrometer Payload (GRASP)
  • Indigenous cryogenic third stage - C25 - Uses Liquid Oxygen -193℃ & Liquid Hydrogen at -253℃ (generates high specific impulse)
  • Cryogenic engine with complex technology only by Russia, US, France, China, Japan and India.
  • 3 stage: 2 solid motor strap-ons (S200), liquid propellant core stage (L110) & cryogenic stage (C-25)
  • Solid booster S200 is the third largest solid booster in the world

LHS 1140 b

  • Habitable planet
  • In Goldilocks zone (habitable zone with moderate temperature)
  • Orbits LHS 1140 – 39 light years away
  • In Super Earth category – 6 times mass & 1.5 times large
  • 1st cited in 1995
  • 2018: James Webb Space Telescope (JWST) by NASA to succeed Hubble – study planets and detect familiar atmosphere will increase
  • 52 potential habitable planets in solar system & 3600 outside solar system

Enceldaus

  • Saturn’s moon – 6th Largest
  • May be habitable
  • Also Jupiter’s 4th largest Moon Europa might be habitable
  • Findings by NASA - Cassini-Huygens unmanned spacecraft (sent in 1997 to study Saturn) & Hubble Telescope
  • Small icy moon
  • Has hydrogen in water plumes
  • Microbes - process of methanogenesis - hydrogen with carbon dioxide dissolved in the water helps to obtain energy

Great Spot on Jupiter

  • Second great spot
  • Great Red Spot in 1830
  • Great Cold Spot - magnetic forces responsible for Jupiter’s polar auroras
