![]() Any burn over 5 will act to change your speed in an upward direction. A burn of 5 units will just cancel gravity and hold your speed constant. You may burn as much or as little of your available fuel as you wish at each step of your descent burns of zero are quite common. You will start the game with 120 units of fuel. In real life, you'd probably survive if the velocity is around -1 but at say -10, you wouldn't be coming back. Means you have landed (or crashed) with non-zero velocity. This lets you perform a 0 fuel burn by simply pressing the CONTINUE button (CONT on the HP-9100B.) (Otherwise the default burn would be all your fuel which is usually not what you want.)Ī perfect landing shows as three zeros. The Fuel is displayed for just a second and then changes to zero. The velocity is shown with a negative sign to indicate downward motion. The velocity, height and fuel are shown in the HP-9100's three line display as -50 (Velocity 50 ft/sec downward)ġ20 (Fuel left: 120 units - this line changes to 0 The game starts off with the rocket descending at a velocity of 50 feet/sec from a height of 500 feet. The object, clearly, is to space your burns just right so that you will alight on the moon's surface with no downward velocity. You'll have to ignite your rockets to slow your descent but if you burn too much too soon, you'll run out of fuel 100 feet up, and then you'll have nothing to look forward to but cold eternal moon dust coming faster every second. You're coming down tail-first, free-falling toward a hard rock surface. Imagine for a moment the difficulties involved in landing a rocket on the moon with a strictly limited fuel supply.
