The solar system has remained an intriguing study to humans since the beginning of time when our ancestors were studying the stars for seasons, navigation, etc. After all, this is partly why NASA exists. Humans have a sense of curiosity that can propel them to study thousands of scenarios over the past thousands of centuries. Now, NASA has a small spacecraft, Orion, an exploration vehicle that will carry the crew to space. Orion missions will launch from Kennedy Space Center in Florida.

Orion re-acquired signal with NASA’s Deep Space Network, at 7:59 a.m. EST after successfully performing the outbound powered flyby burn at 7:44 a.m. EST with a firing of the orbital maneuvering system engine for 2 minutes and 30 seconds to accelerate the spacecraft at a rate of more than 580 mph. At the time of the burn, Orion was 328 miles above the Moon, travelling at 5,023 mph. Shortly after the burn, Orion passed 81 miles above the Moon, travelling at 5,102 mph. At the time of the lunar flyby, Orion was more than 230,000 miles from Earth.

The outbound powered flyby burn is the first of two maneuvers required to enter the distant retrograde orbit around the Moon. The spacecraft will perform the distant retrograde orbit insertion burn Friday, Nov. 25, using the European Service Module. Orion will remain in this orbit for about a week to test spacecraft systems. The distant retrograde will take Orion 40,000 miles past the Moon before it returns to Earth. Orion’s greatest distance from the Earth will be Monday, Nov. 28 at 3:05 p.m. CST at more than 268,500 miles. Orion’s greatest distance from the Moon will be on Friday, Nov. 25 at 3:53 p.m. CST at more than 57,250 miles.

The Deep Space Network, managed by NASA’s Jet Propulsion Laboratory in Southern California, handles communications for Artemis I beyond low-Earth orbit. This includes the mission’s trajectory corrections, powered flyby burns, and insertion into and departure from distant retrograde orbit, while the Near Space Network provides supplemental navigation data with assistance from the Near Space Network’s tracking and data relay satellite constellation.
