SpaceX stood down from an early morning launch on Wednesday (Nov. 30) that would have sent Japan's Hakuto-R lunar lander and its United Arab Emirates rover toward the moon.

The instantaneous launch window was scheduled for 3:39 a.m. (0839 GMT) on Wednesday (Nov. 30), but SpaceX announced the delay in a tweet just over four hours before lift-off. "Standing down from launch of ispace's HAKUTO-R Mission 1 to allow for additional pre-flight checkouts," company representatives wrote.

The launch is now scheduled for another instantaneous window on Thursday (Dec. 1) at 3:37 a.m. EST (0837 GMT) from Florida's Cape Canaveral Space Force Station. You can watch live here at, courtesy of SpaceX, or directly via the company. Coverage will begin about 15 minutes before launch.

When Hakuto-R launches, it will embark on a nearly four-month journey to the moon, which will result in the first-ever soft touchdown by a private company on the lunar surface if all goes according to plan. After the lander is safely on the lunar surface, it will deploy Rashid, a small rover built by the United Arab Emirates (UAE).

The 22-pound (10-kilogram), four-wheeled rover will traverse the moon for one lunar day (14 Earth days) while collecting data about the lunar surface. Rashid is equipped with a high-resolution camera, thermal and microscopic imaging tools, and a probe that will allow it to study the electrically charged environment of the lunar surface. Scientists believe this electrical charge is created by the solar wind, a flow of charged particles constantly streaming off the sun.

The mission will be the first for ispace, which has been developing Hakuto-R for more than a decade after being established in 2010. The company has a second lunar mission planned for 2023, also expected to launch aboard a SpaceX Falcon 9 rocket, ispace representatives have said.

The UAE, meanwhile, has ambitious plans for its space program. Hope, the nation's first Mars probe, began orbiting the Red Planet in February 2021, and the nation's space agency aims to establish a colony on Mars by 2117.

Ispace's Hakuto-R lander was originally intended to land on the moon in 2021, but was delayed due to technical issues. The company hopes to eventually enable the development of settlements on the moon using water ice mined from the lunar surface.
