feel lucky ? consequence such asComet Siding Spring ’s brush with Marsin October only go on about once every eight million years , according to NASA .
And after we were treated tospectacular views from the agency ’s spacecraft , we now have fresh pictures this month from an Native American mission . Also , NASA has resign science results suggesting that the chemistry of Mars ’ atmosphere could be changed forever from the close encounter .
“ The paradigm in the marrow shows a stripe … radiating out of the comet ’s karyon ( out of shape ) , possibly indicating the jet from [ the ] comet ’s nucleus , ” the Indian Science Research Organisation wrote of the above look-alike sequence on itsFacebook mission pageboy .
“ normally squirt represent outgassing activity from [ the ] vents of the comet - nucleus , releasing dust and methamphetamine crystals . The outgassing activity bit by bit increases as the comet moves closer to the Sun . ”
The comet ’s dust likely grow a meteor shower or meteor storm when particles from it crashed into the upper air , which “ literally changed the chemistry , ” added Jim Green , director of NASA ’s wandering science segmentation , in arecent give-and-take play up on an agency blog .
The means says the dust created vaporize metal , which will finally transform to detritus or “ meteoric fastball . ” MAVEN ( which stands for Mars Atmosphere and Volatile EvolutioN ) will be monitoring the tenacious - term effects . Possible results include high - altitude clouds or at the most extreme , perchance for good altering what the chemistry of the aura is . Not a bad thing for a mission to studyshortly after it arrived at Mars .
you’re able to view more science results from NASA ’s work of Siding Springin this late Universe Today tale from Bob King , which speak in more particular about the meteor cascade , new layers in the Mars atmosphere and the ubiquitous detritus .
