Hausj\u00e4rvi, FINLAND \u2014 A rocket stage test firing by Chinese commercial company Space Pioneer ended in catastrophic failure and a dramatic explosion Sunday.<\/p>\n\n\n\n
Space Pioneer conducted what was intended to be a static-fire test of the first stage of its Tianlong-3 launch vehicle at a test facility in Gongyi country, Henan province, Sunday, June 30. <\/p>\n\n\n\n
Amateur footage captured <\/a>by Gongyi citizens and posted <\/a>on Chinese social media shows the nine-engine test stage igntiing and then, exceptionally, taking off. Hold-down clamps and other structures are typically used to securely keep stages in place.<\/p>\n\n\n\n The stage is seen climbing into the sky before halting, apparently with its engines shutting off, and returning to Earth. The stage impacted the ground around 50 seconds after it took off, apparently with much of its kerosene-liquid oxygen propellant remaining, causing a large explosion. The Tianlong-3 first stage would likely fire for a number of minutes on an orbital flight. <\/p>\n\n\n\n
