In 25 seconds, a 10-hour trip by the moon rocket is compressed into a time-lapse video

In the span of a few hours on Tuesday, NASA's next-generation Space Launch System rocket made a journey that couldn't be more different from its August 29 flight.

It took NASA's mega moon rocket just under 10 hours to cover the four-mile journey from the Kennedy Space Center's Vehicle Assembly Building to Launch Pad 39B on Tuesday.

A new era of space exploration will begin in August when NASA's new rocket blasts off for the moon as the most powerful rocket ever built.

In a time-lapse video posted shortly after the SLS reached NASA's launchpad on Wednesday morning, Boeing, maker of the Orion spacecraft, shows the SLS's 10-hour journey in 25 seconds.

NASA's 332-foot rocket was transported to the launchpad on a giant, low-slung vehicle called the Crawler Transporter-2. If loaded, the chunky-looking machine can reach speeds of 1 mph, but in an unloaded state, it can reach speeds of 2 mph.

The SLS rocket is now in place on the launchpad, and engineers and technicians will spend the next couple of weeks configuring systems for the highly anticipated launch in less than two weeks.

“As a result of the wet dress rehearsal campaign, team members have refined operations and procedures,” NASA said in a statement on its website.

NASA's uncrewed Artemis I mission on August 29 will be the first integration test of the SLS rocket and Orion spacecraft. The mission, which is expected to last 42 days, will involve a flyby of the moon followed by a return to Earth.

The first woman and the first person of color will set foot on the moon through Artemis II, which could take place as early as 2025.

Unlike the Apollo missions five decades ago that led humans to the moon, NASA's Artemis program aims to establish a long-term lunar base for astronauts to explore new parts of the moon. In the future, it will serve as a stepping stone for the first crewed Mars mission.
