Yinghuo-1
Yinghuo-1 was a Chinese Mars-exploration space probe, intended to be the first Chinese spacecraft to explore Mars. It was launched from Baikonur Cosmodrome, Kazakhstan, on 8 November 2011, along with the Russian Fobos-Grunt sample return spacecraft, which was intended to visit Mars' moon Phobos.〔〔("Daring Russian sample return mission to Martian moon Phobos aims for November Liftoff" ). Universe Today, 2011-10-13. Retrieved 17 October 2011.〕 The 115-kg (250-lb) Yinghuo-1 probe was intended by the CNSA to orbit Mars for about two years,〔 studying the planet's surface, atmosphere, ionosphere and magnetic field.〔("Back to Mars: Russian probe to visit red planet – Joint observation" ). Russia Today, 2011-09-23. Retrieved 17 October 2011.〕 Shortly after launch, Fobos-Grunt was expected to perform two burns to depart Earth orbit bound for Mars. However, these burns did not take place, leaving both probes stranded in orbit. On 17 November 2011, Chinese state media reported that Yinghuo-1 had been declared lost by the CNSA.〔("Yinghuo Was Worth It" ). Space Daily, Morris Jones, 17 November 2011. Retrieved 19 November 2011.〕 After a period of orbital decay, Yinghuo-1 and Fobos-Grunt underwent destructive re-entry on 15 January 2012, finally disintegrating over the Pacific Ocean.〔("Phobos-Grunt: Failed Russian Mars Probe Falls to Earth" ).

==Name==
Yinghuo-1's name ( – ''firefly'', literally "luminous fire") was a tribute to the near-homophone ''yinghuo'' (). This word, a short form of "shimmering planet" (熒惑星), is an ancient Chinese name for Mars.
