Artemis moon rocket to roll out to launch pad

Engineers and technicians have been busy checking out the cash registers and final testing of the Space Launch System rocket and Orion spacecraft in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The rocket stack made a few trips to the launch pad in March and June for its wet dress rehearsal, a test that simulated every step of the launch without takeoff.

Now it’s time for the real work.

The Artemis team is targeting the first two-hour launch window from 8:33 a.m. ET to 10:33 a.m. ET on Monday, August 29. There are backup launch windows on September 2 and September 5.

The NASA Kennedy YouTube channel will provide a livestream of the rollout, which is expected to begin Tuesday at 9 p.m. ET and run for 10 to 12 hours.

The massive 98-meter stack will take a slow 4-mile (6.4 kilometers) ride aboard one of NASA’s giant Apollo-era crawlers from the assembly building to the launch pad — just like the shuttle missions and Apollo Saturn V rockets once did.

Crawler transporter 2 was used to move the mega rocket stack to the launch pad.

The 6.6 million pound (3 million kilograms) crawler will carry the towering rocket stack and its mobile launcher at a top speed of 1 mile per hour (1.6 kilometers per hour).

The iconic crawler is one of two that have been operating at the Kennedy Space Center for more than 50 years. First commissioned in 1965, the massive transporters can carry 18 million pounds (8.2 million kilograms) each, or the weight of more than 20 fully loaded 777 aircraft, according to NASA. The tracks are so wide that a professional baseball diamond could sit on top.

The unmanned Artemis I will launch on a mission beyond the moon and return to Earth. Once launched, the spacecraft will enter a distant retrograde orbit around the moon, traveling 1.3 million miles (2.1 million kilometers) over the course of 42 days before landing in the Pacific Ocean off the coast on October 10. of San Diego crashes. Orion’s return will be fast and hotter than any spacecraft has ever experienced on its way back to Earth.

The Orion spacecraft will travel more than any other spacecraft built for humans has ever flown, and will reach 44,000 miles further than the far side of the moon, according to NASA.

Snoopy, mannequins and Apollo 11 items will swing by the moon aboard Artemis I

There are no people on board, but Orion will carry 120 pounds (54.4 kilograms) of mementos, including toys, Apollo 11 items and three mannequins.

Commander Moonikin Campos sits in the commander’s seat of Orion, a suitable mannequin capable of collecting data on what future human crews may experience during a lunar voyage. The mannequin will wear the new Orion Crew Survival System suit designed for astronauts to wear during launch and reentry. The suit has two radiation sensors.

Two “phantoms” named Helga and Zohar will ride in other Orion seats. These mannequin torsos are made of materials that mimic a woman’s soft tissue, organs, and bones. The two torsos have more than 5,600 sensors and 34 radiation detectors to measure how much radiation exposure occurs during spaceflight.

This mission will kick off NASA’s Artemis program, which aims to return humans to the moon and land the first woman and first person of color on the lunar surface by 2025 — eventually making way for human beings. exploration of Mars.

Artemis I will also conduct a number of science experiments, some of which will be installed once the rocket and spacecraft arrive at the launch pad.
