The hard road to space...

  • 2010.12.25 - GSLV - Destroyed at T+60 seconds after guidance commands from on-board computer to steering system of strapon boosters were cut off.
  • 2010.12.06 - Proton-M/DM-3 - Block DM-3 upper stage was loaded with 1500 kg excess liquid oxygen in error. This caused a 100 m/s shortfall in the third stage burn into parking orbit. The upper stages and payload reentered over the Pacific.
  • 2010.06.10 - KSLV-I - First stage failure.
  • 2010.06.10 - KSLV-I - First stage failure.
  • 2010.04.15 - GSLV - Third stage failure.
  • 2009.08.25 - KSLV-I - First and second stages operated correctly, but half of payload fairing failed to separate. Extra mass prevented the second stage and payload from reaching orbital velocity, and the satellite reentered over New Guinea.
  • 2009.04.05 - Taepodong - Third stage failure.
  • 2009.02.24 - Taurus - Payload fairing did not separate.

  • 2007.09.05 - Proton/Briz M - Second stage engine failure soon after ignition.

  • 2006.07.26 - Dnepr - First stage engine failed

  • 2002.09.15 - KT-1 - Second stage failure.
  • 2001.09.21 - Taurus 2110 - A problem a few seconds after first stage separation caused the rocket to go off course; it recovered and the remainder of the stages fired, but final cutoff velocity was too low to reach a sustainable orbit.
"
  • 2000.12.27 - Tsiklon-3 - The S5M third stage steering unit failed and the vehicle crashed a few thousand km downrange near Wrangel Island.
"
