After leaving distant retrograde orbit on the afternoon of Thursday, December 1, Orion finished a planned trajectory correction burn to tweak its course towards the Moon. The five-second burn (see video listed below) took place at 9:54 p.m. CST on Thursday, and changed the spacecrafts speed by about 0.3 mph or less than half a foot per second.
On Artemis I, Flight Day 17 (Friday, December 2), teams collected extra images with Orions optical navigation cam and downlinked a wide array of information files to the ground. This included downloading data from the Hybrid Electronic Radiation Assessor, or HERA. The radiation detector measures charged particles that go through its sensing units.
Measurements from HERA and numerous other radiation-related sensing units and experiments aboard Artemis I will assist NASA better comprehend the space radiation environment future crews will experience and develop effective defenses. On crewed objectives, HERA will become part of the spacecrafts care and warning system and will sound a caution when it comes to a solar energetic particle occasion, alerting the crew to nestle. NASA is also checking a similar HERA system aboard the International Space Station (ISS).
Orion brings other experiments to collect information on radiation, consisting of several radiation area keeps track of about the size of a matchbox that tape the total radiation dose during the mission, dosimeters provided by ESA (European Space Agency) mounted inside the cabin to gather radiation data with time stamps to permit researchers to evaluate dose rates during different objective stages, and three “purposeful passengers” collecting extra information on what teams will experience during future objectives. Four space biology examinations, collectively called Biology Experiement-1, are examining the impact of deep space radiation on seeds, fungi, yeast, and algae.
Orion will reenter the lunar sphere of impact on Saturday, December 3, making the Moon the main gravitational force acting on the spacecraft. It will leave the lunar sphere of influence for a final time on Tuesday, December 6, one day after its return powered flyby about 79 miles (127 km) above the lunar surface area.

A total of about 7,940 pounds of propellant has been utilized, which has to do with 150 pounds less that the quantity anticipated prior to launch. Roughly 2,040 pounds of margin is offered beyond what flight controllers prepare to use for the rest of the objective, which is nearly 130 pounds more than expected quantities before launch. About 97 gigabytes of data have actually been sent out to the ground by the spacecraft.
Just after 1 p.m. CST on Dec. 2, Orion was traveling 229,812 miles (369,847 km) from Earth and 50,516 miles (81,298 km) from the Moon, travelling at 2,512 miles per hour (4,043 km/h).
On Artemis I, Flight Day 17 (Friday, December 2), groups gathered additional images with Orions optical navigation video camera and downlinked a broad variety of information files to the ground. On crewed objectives, HERA will be part of the spacecrafts care and warning system and will sound a caution in the case of a solar energetic particle event, alerting the crew to take shelter. Orions optical navigation electronic camera captured this image of the Moon on flight day 16 of the Artemis I objective. Orion uses the optical navigation video camera to record imagery of the Earth and the Moon at different phases and ranges, offering an improved body of data to accredit its efficiency under various lighting conditions as a way to assist orient the spacecraft on future objectives with crew.
