Life on Mars
Why life is possible on Earth but not on mars: some reasons

  1. Our moon is of the right size, able to control the spinning of the earth and its axis of rotation, thus stabilizing our climate and seasons.
  2. ozone layer, which shields molecules on earth from being zapped away by cosmic radiation
  3. gravitational strength of Earth keeps useful gases from escaping off into space.

NASA’s Lunar Reconnaissance Orbiter (LRO)
Used for acquiring 3-D views of the moon’s surface.
PREDICCS

  • web-based tool
  • for predicting and forecasting the radiation environment in near-Earth, lunar and Martian space.
  • It will provide critical information as preparations are made for potential future manned missions to the Moon and Mars.

LCROSS

  • NASA’s Lunar Crater Observation and Sensing satellite,
  • It has detected presence of water locked inside the soil of moon.

Hard x-ray modulation telescope (HXMT)

  • China’s first space telescope.
  • Will be used for studying blackholes.

Zero Gravity effect

  • disembarking astronauts are taller than embarking ones.
  • This growth is due to zero gravity — the vertebrae of the spine spread out.

  1. Sir, thanks for your great help.

  2. Embarking= to board a aircraft or a vehicle
    Disembarking = to leave a aircraft or a vehicle .

  3. 1. Our moon is of the ……
    Sir Mrunal is it typo mistake….or It must be our EARTH is of the…..correct me please!

    1. of ya on kya farak padtha hyi.

      comon
      sense is not comon sayi bola.

  4. 1. Our moon is of the ……
    Sir Mrunal is it typo mistake….or It must be our EARTH is of the…..correct me please!

    1. No it is not.
      Please apply some common sense if not scientific approach.

  5. I am bit confused about ozone layer shielding us from cosmic radiations. Isn,t that role played by Earth’s magnetic field ( aurora events)

  6. And i never thought about Moon playing role in controlling Earth’s spin.
    Thanks.

  7. what is disembarking astronauts, why they are taller than the coming ones, rather it should be embarking ones taller than disembarking one, please anyone if can throw some light on this one :)
