This morning at 1:47 a.m. EST, NASA’s Space Launch System (SLS) launched the agency’s Orion spacecraft on its way to the Moon as part of the Artemis I mission. During this mission, which will pave the way for missions with astronauts, NASA’s Orion spacecraft will journey thousands of miles beyon
, will provide the propulsion to get to DRO. Using the DRO for Artemis I requires the use of four major targeting navigational burns – two close and two far away from the Moon – to enter and exit the orbit.
“Orion will spend about 6 to 19 days in DRO to collect data and allow mission controllers to assess the performance of the spacecraft,” said Nujoud Merancy, chief of the Exploration Mission Planning Office at NASA’s Johnson Space Center in Houston. “The exact duration of Orion’s stay in DRO is determined by when it launches due to orbital mechanics.”
NASA first studied the DRO to support the proposed Asteroid Redirect Mission which paralleled early SLS and Orion development. The plan for ARM was to capture a near Earth asteroid and redirect it to a lunar DRO. Because of the stability of the orbit, the asteroid could stay there for hundreds of years for research purposes without the need to use propulsion to maintain its orbit.
