At a height of 120 m, a small objects falls from. Try to achieve a safe landing by reaching the surface (where the altitude is 0 m) with a velocity in the range of -5 m/s ≤ v ≤ 0 m/s. A lunar landing module is descending toward the moon's surface at a steady velocity of 10 ms. As the module approaches the surface of the moon, use the sliders to change to exhaust velocity and fuel consumption rates and thereby adjust the thrust which propels the rocket upward. Use the slider below to set the initial altitude of the lunar module and click "Play" to begin its descent. The Hakuto-R Mission 1 lander, a small robotic spacecraft built by Ispace, likely crashed into the lunar surface during the landing attempt. spaceflight during which commander Neil Armstrong and lunar module pilot Edwin (Buzz) Aldrin, Jr. Live out your astronaut aspirations by landing a lunar module at the Armstrong Air and Space Museum and step aboard a Space Shuttle at the National Museum. Its total mass is 10334 kg, with 8200 kg accounting for the fuel and the remaining 2134 kg accounting for the module itself. The mass of the module in this simulation is based upon the averages for NASA's Apollo Lunar Modules. The Apollo Lunar Module, originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moons surface during the United States Apollo program. If either of these rates is 0, the net thrust will also be 0 and the module's downward acceleration due to gravity will be unimpeded. In this simulation, the thrust is given by the product of the exhaust velocity (the speed at which combustion gases exit the propelling nozzle) and the rate of fuel consumption. The module must fire its thrusters as it descends, counteracting the downward acceleration due to gravity and thus reducing its speed as it nears the surface. In order to safely land a lunar module, it must have a speed near 0 m/s as it touches down on the moon's surface.
