Teams with Exploration Ground Systems successfully lifted the Orion Spacecraft for the Artemis I mission inside the Vehicle Assembly Building on Oct. 20, 2021. Teams attached the spacecraft to one of the five overhead cranes inside the building and began lifting it a little after midnight EDT. Work is underway to fully secure Orion to the Space Launch System rocket after teams initially placed the spacecraft on top of the rocket earlier today. This operation will take several hours to make sure Orion is securely in place.
Final stacking operations for NASA’s mega-Moon rocket are underway inside the Vehicle Assembly Building at NASA’s Kennedy Space Center as the Orion spacecraft is lifted onto the Space Launch System (SLS) rocket for the Artemis I mission. Engineers and technicians with Exploration Ground Systems (EGS) and Jacobs attached the spacecraft to one of the five overhead cranes inside the building and began lifting it a little after midnight EDT.
Next, teams will slowly lower it onto the fully stacked SLS rocket and connect it to the Orion Stage Adapter. This will require the EGS team to align the spacecraft perfectly with the adapter before gently attaching the two together. This operation will take several hours to make sure Orion is securely in place.
NASA will provide an update once stacking for the Artemis I mission is complete.
Built by teams at ESA (European Space Agency) and aerospace corporation Airbus, the European Service Module for NASA’s Orion spacecraft arrived at NASA’s Kennedy Space Center in Florida on Thursday, Oct. 14, aboard the Russian Antonov aircraft. This service module will be used for Artemis II, the first Artemis mission flying crew aboard Orion. Service module assembly was completed at the Airbus facility in Bremen, Germany, and the module traveled across the world on its journey to Kennedy.
The service module is the powerhouse that will fuel and propel Orion in space. It stores the spacecraft’s propulsion, thermal control, electrical power, and critical life support systems such as water, oxygen, and nitrogen.
The service module will be transferred from the Launch and Landing Facility to Kennedy’s Neil A. Armstrong Operations and Checkout Facility where teams from NASA and Lockheed Martin will integrate it with the crew module adapter and crew module, already housed in the facility.
With Artemis missions, NASA will land the first woman and the first person of color on the lunar surface. Artemis II will be the first crewed flight test of NASA’s Space Launch System and Orion, paving the way for human exploration to the Moon and Mars.

The last piece of Space Launch System (SLS) rocket hardware has been added to the stack at NASA’s Kennedy Space Center in Florida. Crews with NASA’s Exploration Ground Systems and contractor Jacobs added the Orion stage adapter to the top of the rocket inside the spaceport’s Vehicle Assembly Building. To complete the Artemis I stack, crews will soon add the Orion spacecraft and its launch abort system on top of Orion stage adapter.
The Orion stage adapter, built at NASA’s Marshall Space Flight Center in Huntsville, Alabama connects Orion to the Interim Cryogenic Propulsion Stage (ICPS), which was built by Boeing and United Launch Alliance at ULA’s factory in Decatur, Alabama. During the mission, the ICPS will fire one RL10 engine in a maneuver called trans-lunar injection, or TLI, to send Orion speeding toward the Moon.
As Orion heads to the Moon for its mission, the ICPS will separate from Orion and then deploy 10 secondary payloads that are riding to space inside the Orion stage adapter. These CubeSats have their own propulsion systems that will take them on missions to the Moon and other destinations in deep space.
While the ICPS and Orion stage adapter are making it possible for SLS to send its first science payloads to space on this uncrewed mission, they only will be used for the first three Artemis missions. The Exploration Upper Stage (EUS), a more powerful stage with four RL10 engines, will be used on future Artemis missions. The EUS can send 83,000 pounds to the Moon, which is 40 percent more weight than the ICPS. The EUS makes it possible to send Orion, astronauts, and larger and heavier co-manifested payloads to the Moon.
Artemis I will be followed by a series of increasingly complex missions. With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.
Technicians have loaded the last of 10 CubeSats into the Space Launch System (SLS) rocket’s five-foot-tall Orion stage adapter at NASA’s Kennedy Space Center in Florida. After the Orion spacecraft separates from the SLS rocket for a precise trajectory toward the Moon, the shoebox-sized payloads are released from the Orion stage adapter to conduct their own science and technology missions.
SLS’s main goal for the Artemis I mission is to successfully send the uncrewed Orion spacecraft to lunar orbit where it can test out critical spacecraft systems and then return to Earth testing the spacecraft’s heat shield at lunar reentry speeds. The Orion stage adapter connects the rocket to Orion and contains room inside the adapter to provide a rare opportunity to send the CubeSats to deep space using extra lift-capacity on the uncrewed mission. The CubeSats will study everything from the Moon to asteroids to the deep space radiation environment. Each CubeSat provides its own propulsion and navigation to get to various deep space destinations.
Nine of the ten CubeSats were loaded into the adapter earlier this summer. The last CubeSat to be placed aboard was BioSentinel, the sole CubeSat among this group of satellite payloads that contains a living microorganism, and which was refrigerated until loading in order to preserve its biological contents as long as possible for the mission. BioSentinel’s primary objective is to detect and measure the effect of space radiation on living organisms – in this case, yeast – over long durations beyond low-Earth orbit. A similar experiment is being carried out on the International Space Station so that research teams can compare radiation effects experienced on the station about 250 miles above Earth to those encountered in deep space near the Moon, more than 240,000 miles away.
Developed by NASA’s Ames Research Center in California’s Silicon Valley and the agency’s Johnson Space Center in Houston, Loma Linda University Medical Center, and the University of Saskatchewan, It is among the first studies of the biological response to space radiation outside low-Earth orbit in nearly 50 years. Human cells and yeast cells have many similar biological mechanisms, including DNA damage and repair, and BioSentinel’s experiments can help us better understand the radiation risks for long-duration deep space human exploration.
Progress continues to complete stacking for the Artemis I mission and check out the integrated hardware operations. The team recently successfully completed two complex tests: the Umbilical Retract and Release Test and the Integrated Modal Test. Next, the Artemis I Orion stage adapter with the secondary payloads will be moved to the Vehicle Assembly Center at Kennedy Space Center in Florida and added to complete stacking of the rocket. Then, the Orion spacecraft will be stacked on top of the rocket to complete the Artemis I spaceship. Artemis I is the first in a series of increasingly complex missions to send astronauts to the Moon for long-term exploration that sets the stage for human missions to Mars.
