Before the hop, the lander retracted its two deployed instruments — ChaSTE (Chandra’s Surface Thermophysical Experiment) and ILSA (Instrument for Lunar Seismic Activity) — along with the rover deployer ramp. After landing again, the ramp and the payloads were redeployed, and all systems performed as expected. It did so by firing the lander’s engines and rising up by about 40 cm, then moving sideways by about the same distance, and finally landing at a new spot. This was done to demonstrate the technology of relaunching and precision landing on the moon, which is essential for future missions that aim to...
