Houstonians who are eagerly anticipating America’s historic return to the moon now have a new date. Artemis I will now launch on Saturday, September 3, with a two-hour window beginning at 1:17 pm, NASA announced late Tuesday, August 30.

Viewers can tune into the livestream of the rocket and spacecraft at the launch pad on the NASA Kennedy YouTube channel. Additionally, live coverage of events can be found on NASA Television, the NASA app, and the agency’s website.

This comes after the initial August 29 launch was scrubbed. At that time, teams were not able to chill down the four RS-25 engines to necessary temperatures. Teams also caught and quickly managed a hydrogen leak on one of the rocket’s components.

NASA reports that teams are currently addressing and testing both issues in advance of the Saturday launch. Another important component for flight windows — weather — is currently favorable. Meteorologists with the U.S. Space Force Space Launch Delta 45 forecast favorable weather conditions for Saturday. Though some rain showers are expected, they are predicted to be sporadic during the launch window, per NASA.

As space fans are aware, Artemis I is the first flight test of NASA’s Orion spacecraft, Space Launch System rocket (dubbed SLS), and the ground systems at the agency’s Kennedy Space Center in Florida.

“The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight test that will provide a foundation to extend human presence to the Moon and beyond,” NASA notes in a news release. “The mission will demonstrate the performance of the SLS rocket and test Orion’s capabilities over the course of about six weeks as it travels about 40,000 miles beyond the Moon and back to Earth.”

Given the gravity of the launch, NASA planned considerable fanfare for the broadcast, including celebrity appearances by Jack Black, Chris Evans, and Keke Palmer, as well as a special performance of “The Star-Spangled Banner” by Josh Groban and Herbie Hancock. A planned musical performance featured “America the Beautiful” by The Philadelphia Orchestra and cellist Yo-Yo Ma, conducted by Yannick Nézet-Séguin.

Representatives from Johnson Space Center had not received an update on the Saturday broadcast program when contacted on Wednesday, August 31.

Houston and lunar missions have been inextricably tied since NASA’s first launches. In 1962, President John F. Kennedy boldly declared that America would go to the moon before the end of the decade in front of a packed Rice University football stadium.

On July 20, 1969 – a commitment to the late President Kennedy’s directive — Apollo 11 marked its arrival to the lunar surface with a statement heard around the globe from Commander Neil Armstrong, who would take mankind’s first steps on the surface: “Houston, Tranquility base here. The Eagle has landed.”

And the Bayou City has (somewhat tiredly) been the source of a ubiquitous sentence — that is actually a paraphrasing — uttered by Apollo 13 Commander Jim Lovell: “Houston, we’ve had a problem here.” The adjusted “Houston, we have a problem” declaration was later immortalized by Tom Hanks (as Lovell) in the blockbuster Apollo 13.

What will be the next iconic phrase sent back to Houston when NASA’s manned mission readies to land on Earth’s sole satellite? The countdown is on.

UPDATE: NASA halted the Monday, August 29 Artemis I launch attempt at approximately 7:34 am Monday. According to a statement, the Space Launch System rocket and Orion spacecraft remain in a safe and stable configuration. Launch controllers were continuing to evaluate why a bleed test to get the RS-25 engines on the bottom of the core stage to the proper temperature range for liftoff was not successful, and ran out of time in the two-hour launch window. Engineers are continuing to gather additional data.

In less than a week, NASA and its commercial partners are returning humans to the Moon in the first mission of the Artemis Program. All eyes will be on the rocket as it launches Monday, August 29.

Artemis I — the mission's first flight test of the NASA’s Orion spacecraft, Space Launch System rocket — is an uncrewed mission that will launch from Kennedy Space Center in Florida before circling the moon. The SLS rocket is targeted to launch during a two-hour window that opens at 7:33 a.m. on Monday, August 29, from Launch Pad 39B at Kennedy.

Coverage of the launch has already started, and viewers can tune into the livestream of the rocket and spacecraft at the launch pad on the NASA Kennedy YouTube channel. Additionally, live coverage of events started airing on Monday on NASA Television, the NASA app, and the agency’s website. The launch countdown will begin Saturday, Aug. 27, at 9:23 a.m.

While launch is the main event, the broadcast will also include celebrity appearances by Jack Black, Chris Evans, and Keke Palmer, as well as a special performance of “The Star-Spangled Banner” by Josh Groban and Herbie Hancock. It also will feature a performance of “America the Beautiful” by The Philadelphia Orchestra and cellist Yo-Yo Ma, conducted by Yannick Nézet-Séguin.

"The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight test that will provide a foundation to extend human presence to the Moon and beyond," NASA reports in a news release. "The mission will demonstrate the performance of the SLS rocket and test Orion’s capabilities over the course of about six weeks as it travels about 40,000 miles beyond the Moon and back to Earth."
