F9 Second stage: Estimate 4.2m high 3.6m dia Mass in orbit after S/C sep and depletion: UNKNOWN Guess at 2500 kg (3000 kg Ed Kyle 44000f?) Propulsion: 1 x Merlin Vac Targeted Orbital parameters: (first flight) Perigee x Apogee 250 x 250 km (needs confirmation) Inclination 51.6 deg

Dragon has 6000 kg cargo capacity and 1290 kg prop.

Capsule is 2.9m high 3.6m dia. Cone is 2.4m dia 1.8?m high. Standard Trunk section is 2.3m high 3.6m dia.

F9/Dragon overall: Size 55.0m high 3.6m dia Mass 14000 kg empty? 325000 kg full

F9 First stage: Estimate 36.0m high 3.6m dia Includes 3.6m dia 8.0m high interstage Mass: UNKNOWN Guess at 11500 kg dry (14730 kg Ed Kyle 276000 f) Apogee parameters: Guess 150 km, velocity unknown Propulsion: 9 x Merlin 1C

F9 Second stage: Estimate 4.2m high 3.6m dia Mass in orbit after S/C sep and depletion: UNKNOWN Guess at 2500 kg (3000 kg Ed Kyle 44000f?) Propulsion: 1 x Merlin Vac Targeted Orbital parameters: (first flight) Perigee x Apogee 250 x 250 km (needs confirmation) Inclination 51.6 deg

Dragon Spacecraft, total: Mass: UNKNOWN but F9 reported mass to 200 km, 51.6 deg is 9800 kg. Reported capacity of 6000 kg cargo and 1290 kg prop leaves 2500 kg for spacecraft (Capsule + Trunk) dry mass

Dragon Nose Cone: Cone is rounded cap about 2.4m dia 1.8m? high Mass: UNKNOWN Separation time: UNKNOWN seconds after launch

Dragon Capsule: Capsule is 2.9m high 3.6m dia truncated cone. Mass: UNKNOWN Propulsion: 12 to 18 x Draco 400N NTO/MMH thrusters (dummy on Qual) Propellant: 1290 kg NTO/MMH (not on Qual) Separation: Not clear if Capsule and Trunk will sep on Qual S/C

Dragon Trunk: Extended Trunk is 4.3m high 3.6m dia, this seems to be the version being used Mass: UNKNOWN Separation: Trunk and Falcon Stage 2 will separate on Qual S/C (confirm?) Sep time: UNKNOWN time after stage 2 engine cutoff.

Navstar 62

 2010-022A


SVN62 was Block IIF SV-1, PRN 25, Plane B.

The GPS Block IIF satellites are to replace the Block IIR. Block IIF has a civilian L5 channel. [249] The initial contract was for 6 satellites from Rockwell/Seal Beach; manufacturing was transferred to Boeing/El Segundo in 2001.

Boeing/ES satellite. Mass 1630 kg launch (MOB). Size 2.5 x 2.0 x 1.8m +box + 2 panels. IIF solar array deplyed 7.8m each; estimate 18m span.

Launch by EELV in 2008.
