At 10.13 on Sunday, December 4, NASA’s Orion spacecraft brought out its second necessary flight correction burn. However, the spacecraft ran into a problem with its power conditioning distribution unit shortly after making contact with the Deep Space Network’s Canberra ground station (PCDU). The downstream power was controlled by four securing current modifiers on the PCDU that were turned off. These switches connect to the heater and pressures subsystems, according to NASA. The space agency witnessed to the unity of Orion’s systems and the achievement of the next element recharge. The navigation and communication systems of the spacecraft were not affected by this problem, and no critical systems experienced power interruption as a result.

On Monday, December 5, Orion will be 127 kilometres above the lunar surface as it makes its closest approach to the Moon. On the same day, at 10:13 PM, it will conduct a powered return happen that will last about 3 minutes, 27 seconds. This will be the mission’s largest activity as well because Orion’s speed will be changed by roughly 1,000 km/s . The spacecraft will then only need to make small route corrections until it returns to Earth.Teams from the US Navy and NASA’s research Ground Systems finished their final training day at sea where they used a copy capsule in the water so that divers could practise open-water recovery techniques and on December 11th, Orion is expected to make a splash in the Pacific.
