Science Always Surprises In Its Beginning (at least) !We Have Learned The Other Day That 'WATER-ICE' Could Exist And, That Too, In Abundance, On The Warmest Of Surfaces !Yes, The Smallest, The Closest(to Sun) And The Warmest Of All Planets, MERCURY Has Multi Millions Tons Of Water Ice ! The Special Spacecraft, MESSENGER (MErcury Surface Space ENvironment GEochemistry and Ranging ) Sent Last Year In March By NASA, Has Sent Plenty Of Information N Data In Support Of The Hitherto Held WATER HYPOTHESIS ON MERCURY.
A Team Of Expert Scientists Hailing From NASA, UNIVERSITY OF WASHINGTON APPLIED PHYSICS LABARATORY(APL),UNIV. Of CALIFORNIA,LOS ANGELES(UCLA),JOHNS HOPKINS UNIV. . . .et.al Have Been Analyzing The Findings And Have Come To The Conclusion That The Warm Planet Has Evidence Of Tons Of Ice Trapped In Polar Craters,Especially On The North Pole Of Mercury !
IT'S NOT THE FIRST TIME THAT SCIENTISTS HAVE OBSERVED THIS UNUSUAL THING !
In 1970s n 90s ,Lots Of Radar Mappings Were Done Which Had Shown Places Of 'BRIGHT PATCHES' On The Surface Of Mercury. But, Those Findings Were Not Strong Enough To Be Conclusive!
This Time The Evidence Is Technically Stronger Due To The Equipments Applied For Mapping The Topography Of The Smallest Planet,MERCURY -That Makes A Round Of The Sun In Merely 88 Days!
Advanced ALTIMETERS Were Used That Is Based Upon Laser Techniques For A Clear, Closer n In-Depth Mapping Through The Use Of Millions Of Laser Pulses!
The Second Equipment In Probe Was NEUTRON SPECTROMETER For Detecting The Presence Of Hydrogen And Hence The Possibility Of Water !
Both The Equipments Have Sent Countless Images And Data That Have Come In Handy For Reaching The Conclusion.
One Of The Vital Findings Was To Measure The Surface REFLECTANCE To Verify The Nature Of Reflection Plus The Penetration Of Sun Rays !
Along With The White(Bright) Patches, There Is Another Kind Of Spots : The Black or Dark Patches !The Concerned Scientists Have Concluded These Dark Patches As Places Of Complex Carbonic Materials , Which Might Have, As They Guessed, Been Due To The Attacks Of Comets n Asteroids On The Mercury Surface In Due Course Of Time!
The Tilt Of Mercury Is Less Than 1-degree And That Makes Its Rotation In Such A Way That Some Areas Of The Polar Regions Do Not See The Light Of Day And These Areas Have Sufficient Ice That Might Be Helpful In Explaining And Understanding The Origin Of Life On Our Planet !
Good Luck To The Involved Scientists n Institutions !
