Space Probes

Introduction:

     A space probe is a spacecraft, that explores beyond earth. It orbits other planetary bodies, lands on another astronomical body and penetrates into interstellar or outer deep space. One of the promising and amazing technology made space probe is Voyager-1, which have been exploring outer space since 37 years. There have been many space probes launched and operated by many space agencies. Example : NASA, USSR, ESA, ISRO, JAXA etc...

Interplanetary Trajectory:

     Probes which orbit the sun like a planet orbit beyond the vicinity of Earth is said to be interplanetary trajectory probes. It uses simple method to reach faster with less fuel called Hohmann transfer orbit, gravitational slingshots. 

Notable launched Probes:

• Voyager-1 and Voyager-2
• Pioneer-10 - 23 January 2003
• Pioneer - 11 - 23 January 2003
• New Horizons - 19 January 2006
• Juno - 8 August 2011
• Dawn - February 2017
• Cassi-Huygens - 15 October 1997
• Rosetta - November 2014
• Hayabusa 
• Genesis
• Giotto
• Sojourner - Spirit and Opportunity Rover
• Mars-3
• Mariner 9 - 13 November 1971
• Venera -7 - Venus probe
• Venera-4
• Mariner - 10 
• Luna-16
• Luna 3
• Luna 9

Conclusion:

          In our modern days, we have successfully launched many probes into deep space. Space-X interplanetary transport system will change the view of interplanetary travels into deep space and planet Mars. Mars direct, Mars One are some of the future probing missions.
