• In 1998 - The planet Climate Satellite is launched but is lost.
• In 1999 - another satellite is launched but it fails within 10 months.
• In the year of 2001's April month - the planets journey satellite is launched, it reaches at the planet after six months.
• June 2003 - other space agency of Europe releases the Mars Express Satellite, but they never makes a contact by releasing that satellite. this agency declared to this planet as Red Planet by the study of two years.
• after that one more satellite is launched in June 2003. Both satellites are part of NASA's mission.
• In January 2004 - first satellite of European agency lands on Mars and send pictures from the ground. this satellite started the study of rocks and soil of the ground.
• after 10 days second one satellite reaches at this planet by that both satellites are actively worked and collected the samples.
• In 2005 - the mars intelligence space platform launches. it will scan the planet for more samples of water. apart from that in the month of march-2006 - the intelligence space station stop on planet and makes its path. it contains more successful camera ever. which takes first four pictures by the distance of 500 to 2400 miles.
• after three years of its landing, chance continue to its mission of research the Martian terrain in January - 2007.
• by august 2007 - NASA's another satellite launched successfully which named as Phoenix lander. Rocket of satellite made in Florida which takes around 10 months to reach.

• In March 22-2010 - got hearing from European satellite which is currently working on its mission.
• September 2010 - Scientists got the data from the Phoenix Lander satellite, the data suggests that Mars' atmosphere has been filled up by carbon dioxide.
• In 2011 - scientists has  lost the contact from one European satellite. 
• In 2012 - another satellite lands on Mars which named as Curiosity.
• Five articles released in September 2013 which informed about two percent water by weight.
• 2014 - India's Mars weather satellite mission successfully enters mars' route and becoming the first nation to arrive its first attempt.
• In 2015 India's satellite completes its 160 days mission and still operating.
• In the march of 2016 - European space agency launches another spacecraft to detect atmospheric locations of the planet.
• In year 2018 - NASA launches robotic explorer to study the interior of mars. 
• Italian space agency publish a study reflecting that a lake of liquid water detected by using the European space agency's data.
• In February 2019 - NASA declares that the mission is complete which one they started in the year of 2003 and they are unable to contact that satellite.
• In July 2020 - NASA sends expertness helicopter and one space investigator machine named as Perseverance rover into space. which lands on Mars after six months.
