CONCLUSION

The MARS-96 spacecraft was been launch on 16 November 1996 at 20:48:53 UTC from Baykonur.

Time schedule of the main events during the launch are following:

Events	T, s since Lift-off	Relative V, mps	Height, km
Lift-off Command	-2,8	0	0
Lift-off	0	0	0
of 1st stage engines thrust	1,6	7	0.008
Max velocity head	66	459.5	11.2
2nd stage engine ignition	118,94	1551.3	39.4
1st stage separation	123.29	1677.9	42.5
Payload fairing separation	185.00	2151.2	78.2
3rd stage engine ignition	327.74	4349.3	119.5
2nd stage separation	331.14	4417.6	120.6
Payload (Block-D, SC, adapter, lower casing, middle casing) separation	583.42	7202.4	144.7
Middle casing separation	638.42	-	-
1st ignition of the Block D main engine's launching provision system (SOZ)	643.42	7188.1	155.6
1st ignition of the Block-D main engine	942.42	7175.3	166.0
of the Block-D main engine thrust, SOZ-burn-out	942.84	7191.9	165.9
Block-D main engine burn-out	1038.98	7519.9 (V_abs=7843.1)	160.1
Insertion into the near Earth orbit	1046.9
2nd ignition of the SOZ engine	3833.81	7485.8	163.2
Payload entry into the Earth's shadow	4032	-	-
2nd ignition of the Block-D main engine	4132.81	7488.0	159.5
of the Block-D main engine thrust, SOZ-burn-out	4133.23	7488.1	159.5

During the second switch on of the Block-D the operations stipulated by the onboard program were not implemented. Block-D did not impart the requirement impulse to the spacecraft and separated from the spacecraft. Due to the MARS-96 spacecraft was not been inserted into the interplanetary trajectory to Mars and during the third revolution around the Earth insert into the Earth's atmosphere and felt in the Pacific.
