Orion surpasses Apollo 13 record distance from Earth: Flight Day 11

On day 11 of the Artemis I mission, Orion continues its journey beyond the Moon after entering a distant retrograde orbit Friday, Nov. 25, at 3:52 p.m. CST. Orion will remain in this orbit for six days before exiting lunar orbit to put the spacecraft on a trajectory back to Earth and f a Sunday, Dec. 11, splashdown in the Pacific Ocean.

Orion surpassed the distance record for a mission with a spacecraft designed to carry humans to deep space and back to Earth, at 7:42 a.m. Saturday, Nov. 26. The record was set during the Apollo 13 mission at 248,655 miles from our home planet. At its maximum distance from the Moon, Orion will be more than 270,000 miles from Earth Monday, Nov. 28.

Engineers also completed the first orbital maintenance burn by firing auxiliary thrusters on Orion’s service module at 3:52 p.m. for less than a second to propel the spacecraft at .47 feet per second. The planned orbital maintenance burns will fine-tune Orion’s trajectory as it continues its orbit around the Moon.

Flying aboard Orion on the Artemis I mission is a suited manikin named after a key player in bringing Apollo 13 safely back to Earth. Arturo Campos was an electrical engineer who developed a plan to provide the command module with enough electrical power to navigate home safely after an oxygen tank aboard the service module of the Apollo spacecraft ruptured. Commander Moonikin Campos is outfitted with sensors to provide data on what crew members may experience in flight, continuing Campos’ legacy of enabling human exploration in deep space.

Artemis builds on the experience of Apollo. With Artemis, humans will return to the lunar surface, and this time to stay. NASA will use innovate technologies to explore the Moon’s South Pole and more of the lunar surface than ever before using the Gateway space station in lunar orbit along with advanced spacesuits and rovers.

NASA will lead the way in collaboration with international and commercial partners to establish the first long-term presence on the Moon. Then, we will use what we learn on and around the Moon to take the next giant leap: sending the first astronauts to Mars.

Orion enters distant retrograde orbit around Moon: Flight Day 10

Flight Controllers in the White Flight Control Room at NASA’s Johnson Space Center in Houston successfully performed a burn to insert Orion into a distant retrograde orbit by firing the orbital maneuvering system engine for 1 minutes and 28 seconds at 4:52 p.m. CST, propelling the spacecraft at 363 feet per second. Shortly before conducting the burn, Orion was traveling more than 57,00 miles above the lunar surface, marking the farthest distance it will reach from the Moon during the mission. While in lunar orbit, flight controllers will monitor key systems and perform checkouts while in the environment of deep space.

The orbit is distant in that Orion will fly about 40,000 miles above the Moon. Due to the distance of the orbit, it will take Orion nearly a week to complete half an orbit around the Moon, where it will exit the orbit for the return journey home. About four days later, the spacecraft will harness the Moon’s gravitational force once again, combined with a precisely timed lunar flyby burn to slingshot Orion onto its return course to Earth ahead of splashdown in the Pacific Ocean on Sunday, Dec. 11.

On Saturday, Nov. 26, Orion spacecraft will break the record for farthest distance traveled by a spacecraft designed to carry humans to space and safely return them to Earth. This distance is currently held by the Apollo 13 spacecraft at 248,655 miles (400,171 km) from Earth. Orion was specifically designed for missions to carry humans farther into space than ever before.

On Artemis I, engineers are testing several aspects of the Orion spacecraft needed for deep space missions with crew, including its highly capable propulsion system to maintain its course with precision and ensure its crew can get home, communication and navigation systems to maintain contact with the ground and orient the spacecraft, systems and features to handle radiation events, as well as a heat shield that can handle a high-speed reentry from the Moon. Both distance and duration demand that spacecraft must have systems that can reliably operate far from home, be capable of keeping astronauts alive in case of emergencies and still be light enough that a rocket can launch it.

Artemis II will test the systems required for astronauts to live and breathe in deep space. Long duration missions far from Earth drive engineers to design compact systems not only to maximize available space for crew comfort, but also to accommodate the volume needed to carry consumables like enough food and water for the entirety of a mission lasting days or weeks.

European Service Module powering Orion to the Moon and back

Paris (ESA) Nov 24, 2022


The European Service Module is powering Orion around the Moon and back, providing propulsion, temperature control, electricity as well as storage and delivery for essential supplies such as fuel, water and air. This first Artemis mission is an uncrewed test mission, putting the spacecraft through its paces preparing to send astronauts forward to the Moon.

After liftoff at 07:47 CET (06:47 GMT, 01:47 local time) on 16 November, the European Service Module unfolded its 7-m solar wings to start gener … read more
