At orbital apogee the Orion spacecraft orient prior to Mars transfer burn. They will make the crossing at 125,490 fps – a 39 day fast transfer trajectory to Mars (85,562 mph/137,700 kph).

Image is part of a future historical setting, more detail is found on my profile page under the heading Orion’s Arm Future History, A Synopsis. A Timeline Graph is to be found here: Timeline.

The vehicles have shed their forward payload shroud, and from this angle details of the nuclear pulse system are fully visible: pusher-plate, bomb aperture (centered in the pusher-plate), and the bomb placement gun (located ahead of the pusher-plate and inside the ring of the second-stage shock absorbers) identifiable by its conical plasma shield. The first-stage shock absorbers are gas filled torridal bags – visible as black bands along the body of the pusher-plate – the second-stage shock absorbers are the long-arm shock absorbers positioned between the pusher-plate and the main hull of the vehicle. The two sets of shock absorbers are de-tuned in relationship to one another in order to step down the powerful 150 km/sec (300,000 mph) slam of the plasma (generated by the nuclear impulse device) to something man and machine can stand.
