SLS rocket ready to send humans to the moon, NASA says

All Mega Missile Systems SLS from POT they did an exceptional job Artemis I and structures are ready for manned flight in Artemis II.

This is the conclusion of the space agency based on an assessment made shortly after the first rocket launch with the Orion spacecraft on November 16, and preliminary data after the flight. Rocket SLS Meets or exceeds all performance expectations POT.

Moon landing approaching

With the program Sagebrush, POT will land the first woman and the first colored person on the surface Moon – expected in 2025 – paves the way for a long-term presence on the Moon and serves as a springboard for astronauts on their way to Mars.

Before launch, the teams set performance benchmarks for the rocket through a series of pre-flight simulations and test campaigns. During launch and ascent into space, the rocket experienced dynamic phases such as extreme loads and temperatures that affected its performance. flight tests Artemis I it was the only way to collect real data on the behavior of the rocket in situations such as fuel separation.

Engineers from the SLS Design and Support Center at the Space Flight Center. Marshall POT collected over four terabytes of data and images aboard the SLS during the pre-launch and launch phases. In addition, a total of about 31 terabytes of image data was collected from ground-based cameras, rocket cameras, and airborne cameras that were focused on the spacecraft alone. SLS. For comparison, the printed materials of the US Library of Congress are about 20 terabytes.

“The data we received from Artemis I are critical to building confidence in this rocket that will send humanity back to Earth. MoonThis is stated in a statement by John Blevins, Chief Engineer SLS.

everything is fine

Cameras and sensors also allowed the teams to monitor the behavior of the rocket during its maneuvers in space. See the launch from the “view” of the rocket SLS This meant strategic placement of cameras, sensors, and other measurement tools throughout the rocket, mobile launcher, and launch pad.

The engineers also monitored the extreme temperatures and sounds that the rocket made immediately after launch. Post-flight data SLS showed that the thrust and mixture ratio control valves on the RS-25 engines were within 0.5% of the calculated values. The mixture ratio is the proportion of fuel and oxidizer that determines the temperature and thrust of the engines during their eight-minute flight. The remaining pressures and internal temperatures of the engines were within 2% of the values ​​predicted before the flight.

In-flight main stage SLS successfully performed all its functions and placed the ICPS and the Orion spacecraft into an initial Earth orbit of 972.1 miles by 16 miles. The insert was only 2.9 miles from the ideal target of 975 miles for 16 miles and within acceptable parameters. After a near-perfect translunar injection, the ICPS spacecraft and Orion successfully separated, allowing Orion to complete the 25.5 day mission. (Europe Press)
