It is launch day for NASA, once more.

The area company is aiming to launch its Artemis I moon mission within the early hours of Wednesday morning, after technical points delayed earlier makes an attempt over the past three months.

The company’s towering Area Launch System (SLS) rocket and Orion capsule are scheduled to elevate off throughout a two-hour launch window that opens at 1:04 a.m. ET. If profitable, the Artemis I mission would final 26 days in whole earlier than Orion returns to Earth.

The uncrewed launch marks the debut of probably the most highly effective rocket ever assembled and kicks off NASA’s long-awaited return to the moon’s surface. It is the primary mission in NASA’s Artemis lunar program, which the company hopes will result in touchdown astronauts on the moon by its third mission in 2025.

Whereas Artemis I cannot carry astronauts, nor land on the moon, the mission is important to demonstrating that NASA’s monster rocket and deep area capsule can ship on their promised talents.

Artemis I is 5 years not on time and billions of {dollars} over funds. Greater than $40 billion has already been spent on this system, a lot of that towards SLS and Orion’s improvement. The system comes with a per-launch price ticket of $4.1 billion.

NASA first tried to launch Artemis I in August however has referred to as off a number of makes an attempt since then after discovering technical problems with the rocket’s engines.

In September the company rolled the rocket back into the Vehicle Assembly Building (VAB) for cover from Hurricane Ian, returning the car to the LC-39B launchpad on Nov. 3.

NASA final week left SLS and Orion out on the launchpad to climate the winds of Hurricane Nicole.

NASA stated it checked the rocket and spacecraft after the storm handed and located no main injury to the car. It stated a 10-foot part of insulation close to the Orion capsule had pulled away as a result of excessive winds – however NASA determined to proceed with Wednesday’s launch try after an evaluation confirmed it isn’t anticipated to trigger any important injury if the insulation falls off throughout the launch.

If wanted, NASA has a back-up launch date scheduled for Nov. 19.
