Official launch time 06:21UTC

There are less than 14 hours to go on the countdown clock, and all is still ‘go’ for launch.

Note that the launch time is now officially set at: 11:51hr IST, or 06:21 UTC. The launch window is 15 minutes.

Today we finalized the preparations for communications with ISIS in Delft and the teams at their respective locations. We also contributed to make an offer to the temple here at the launch base, as a prayer for a good launch.

During a preparatory visit to the Mission Control Center (MCC) today, we were also provided with the latest preliminary orbit parameters. Those were converted to the following TLEs and given in the sequence of deployment:

Notes with respect to these TLEs:

  • The TLEs have been put together by ISIS with the greatest care, but we can not guarantee their correctness.
  • As they are based on the preliminary orbit parameters, they are also preliminary.
  • Both the satellite number and the international designator are arbitrarily chosen by ISIS. Obviously these items will be determined (by others than ISIS) once the launch has taken place and each satellite has been identified.
  • The epoch time used is in UTC.
  • The First Time Derivative of the Mean Motion, Second Time Derivative of Mean Motion and BSTAR drag terms are set to zero as no information about these parameters of each CubeSat is known.
