The […] test was conducted using a qualification version of the propulsion system at NASA’s White Sands Test Facility near Las Cruces, New Mexico. While the system never left the ground, it simulated one of the most taxing situations the spacecraft’s engines could encounter after launch.

This test simulated what is referred to as an abort-to-orbit scenario. In the event the interim cryogenic propulsion stage (ICPS) was unable to set the spacecraft on its path to the Moon, Orion would deliberately separate early from the ICPS and the ESA (European Space Agency)-provided service module’s engines would fire to boost the spacecraft into a safe, temporary orbit. That would allow time to evaluate the crew and spacecraft before a decision is made to either continue with an alternate mission profile, or return to Earth. Under an alternate mission profile, Orion and its crew may still be able to accomplish some of the mission objectives even if the trajectory and the primary mission objective has changed.

During the successful test, engineers simulated the abort-to-orbit scenario by firing the Orion main engine on the service module, in addition to all eight of its auxiliary engines simultaneously. Each of the reaction control thrusters were also periodically fired throughout the test to simulate attitude control and overall propulsion system capacity.

The Artemis program is an ongoing crewed spaceflight program carried out by NASA, U.S. commercial spaceflight companies, and international partners such as ESA, with the goal of landing “the first woman and the next man” on the lunar south pole region by 2024. Artemis would be the first step towards the long-term goal of establishing a sustainable presence on the Moon, laying the foundation for private companies to build a lunar economy, and eventually sending humans to Mars.

In 2017, the lunar campaign was authorized by Space Policy Directive 1, utilizing various ongoing spacecraft programs such as Orion, the Lunar Orbital Platform-Gateway space station, Commercial Lunar Payload Services, and a yet-to-be-developed crewed lander. The Space Launch System will serve as the primary launch vehicle for Orion, while commercial launch vehicles are planned for use to launch various other elements of the campaign. NASA requested $1.6 billion in additional funding for Artemis for fiscal year 2020, and full funding has yet to be approved by Congress.

During the successful test of Orion’s launch abort system, known as Ascent Abort-2, a camera mounted on a ring connecting the crew module and launch abort system to its booster captured a view of Orion escaping the booster. After the booster separated, its motor continued to burn for several seconds and maintained stability, which allowed for a clear, mid-air view of the Orion elements continuing to execute the abort test. About 27 seconds after the abort is initiated and the Orion elements separate from the booster, the launch abort system’s jettison motor is seen firing, releasing the capsule.

The July 2 test demonstrated the Orion’s launch abort system works during high-stress aerodynamic conditions and can pull the capsule to safety if an emergency ever arises during launch. The test was a critical milestone needed to help pave the way for Artemis missions with astronauts.

Sonification is the process of translating data into sound and music. In this musical data sonification of lunar knowledge and exploration, we can hear the progress made throughout the Apollo program to now as our understanding of the Moon expands. Listen to the percussion, which signals launches and the passage of time; the pitch of the string and brass instruments conveys the amount of scientific activity associated with the Moon over time.

NASA’s Lunar Reconnaissance Orbiter mission now celebrates its 10-year anniversary of being at the Moon. After launching on June 18, 2009, and entering lunar orbit on June 23rd, the spacecraft continues to collect vast amounts of data vital to our understanding of the lunar landscape and environment, our solar system, and to our future exploration goals for the Moon and Mars. This video highlights some notable facts and accomplishments of the LRO mission over the past decade, all of which are paving the way forward for reestablishing a human presence on the Moon with the newly announced Artemis program.
