The Orion spacecraft will fly near the Moon’s surface twice before starting its engines to return to Earth in mid-December, ending the Artemis 1 mission..
The Artemis mission lifted off on November 16 at 1:47 p.m. Hanoi time from Launch Pad 39B at NASA’s Kennedy Space Center, marking the rocket’s first launch. Space Launch System (SLS) giant and began the 25-day flight to the Moon and back to Earth of the unmanned spacecraft Orion.

Orion ship will spend the next 6 days flying to the Moon. On November 21, the Orion spacecraft will fly past the Moon at its closest distance, about 100 km from the surface. This operation will take advantage of the Moon’s gravity, pushing the Orion spacecraft further. The service module will then perform a second burn on November 25 to place the spacecraft into a distant retrograde orbit (DRO). There, the spacecraft will spend a week at an altitude of about 61,000 km above the surface of the Moon. On November 28, the Orion probe will beat Apollo 13’s record for the vehicle capable of carrying people farthest from Earth, reaching a distance of nearly 483,000 km.
While in DRO, a series of active and passive sensors aboard Orion will measure radiation and other flight conditions, allowing researchers to better understand the conditions astronauts will experience during a manned mission . Even though Artemis 1 is an unmanned mission, Orion still has dummy passengers.
Attached to the capsule’s command seat is a mannequin named Moonikin Campos from NASA, equipped with a radiation sensor inside. Sensors on the seat will record gravity and vibrations throughout the flight. The Campos who accompany them are two effigies of Helga and Zohar with only the upper half of the body and no arms, contains more than 34 active radiation dosimeters and 6,000 passive radiation dosimeters, helping to study the effectiveness of the specialized AstroRad radiation blocking suit.
Helga and Zohar are made with materials that simulate human bones and muscle tissue. Their bodies include many parts related to female anatomy to simulate radiation-sensitive ovarian and breast tissues. This supermodel duo is inside Matroshka AstroRad Radiation Experiment (MARE)What does Zohar wear? AstroRad suit and Helga serves as an object of comparison. When the dummies return to Earth, researchers will compare their radiation exposure.
If effective, the AstroRad suit will allow astronauts to perform missions around the spacecraft. Due to the lack of protection from magnetic fields in low Earth orbit, more distant areas of the planet are more sensitive to radiation, so astronauts are at higher risk of radiation exposure.
On December 1, Orion’s service module will burn to leave DRO, brought the spacecraft closer to the Moon 4 days later. Next, the service module will perform the final burn so that the Orion craft can begin its return journey to Earth in 6 days.
On December 11, the Orion will plunge into Earth’s atmosphere at a speed of 40,000 km/h, a major test for the ship’s cabin and heat shield when subjected to temperatures of up to 2,750 degrees Celsius. The Orion will then parachute into the Pacific Ocean, ending the Artemis 1 mission.
If the Artemis 1 mission goes smoothly, Artemis 2 will carry astronauts around the Moon in 2024 and Artemis 3 will carry the crew to the Moon’s south pole a year later. From there, NASA will continue to build a durable base on and around the Moon’s surface, the primary goal of the Artemis program.
