NASA’s mega moon rocket heads to launchpad next week

NASA is about to take a big step toward the launch of its Artemis I lunar mission when it transports its next-generation Space Launch System (SLS) rocket to a launch pad at the Kennedy Space Center in Florida for testing next week.

NASA’s giant crawler vehicle will haul the SLS rocket — with the Orion spacecraft on top — from the Vehicle Assembly Building to Launch Pad 39B on Thursday, March 17, the space agency announced.

The four-mile journey (shown below) will take between six and 12 hours to complete. Fans of slow TV can watch the rocket’s arrival at the launch pad by visiting the Kennedy Newsroom YouTube channel from around 4 p.m. that day.

“At the pad, NASA will conduct a final prelaunch test known as a wet dress rehearsal, which includes loading the SLS propellant tanks and conducting a launch countdown,” the space agency said. The results of the test will enable NASA to determine if it’s ready to move forward with mission activities.

The fully stacked SLS rocket stands at 322 feet (98.1 meters) and, when it blasts off from the launchpad for the very first time, will create around 8.8 million pounds of thrust — 13% more than the space shuttle and 15% more than the Saturn V rocket that powered astronauts to the moon during the Apollo lunar missions five decades ago.

If testing goes to plan, Artemis I could get underway in May, with the SLS rocket sending the Orion spacecraft on a crewless flyby of the moon in a mission lasting around 26 days.

If the rocket functions as it should and Orion returns safely to Earth, Artemis II will send a crew on the same journey in the next couple of years. Following that, Artemis III will send the first woman and first person of color to the lunar surface before the end of the decade in what will be the first crewed landing since 1972.

The early Artemis missions will also pave the way for a long-term lunar presence and serve as a stepping stone for crewed voyages to Mars and possibly beyond.

By all accounts, NASA’s Artemis I mission has been going extraordinarily well, setting up the space agency for a crewed landing on the lunar surface possibly as soon as 2025.

The mission started on November 16 with the maiden flight of NASA's Space Launch System (SLS) rocket, the most powerful space vehicle ever to have flown.

NASA has shared remarkable footage showing its Orion spacecraft passing over the lunar surface at an altitude of just 687 miles.

The flyby, which at one point took the uncrewed spacecraft to within 79 miles of the moon’s surface, took place on Monday, December 6, just over three weeks after the Orion left Earth on the Artemis I mission. The spacecraft made a similarly close approach to the lunar surface last month, too.

The performance of NASA's Orion spacecraft has exceeded the agency's expectations -- and the Artemis I mission isn’t even over yet.

After departing the Kennedy Space Center in Florida atop NASA’s new Space Launch System (SLS) rocket on November 16, the uncrewed Orion passed over the surface of the moon at an altitude of just 81 miles. It then entered what’s known as a distant retrograde orbit where it stayed for several weeks, and is now about to begin its voyage home.
