Firefly Aerospace successfully landed its spacecraft on the Moon on Sunday, marking only the second private mission to achieve the milestone – and the first to do so upright!

Blue Ghost Mission 1 touched down shortly after 3:34 AM ET near Mons Latreille, a volcanic formation in Mare Crisium on the Moon's northeastern near side.

"Y'all stuck the landing, we're on the Moon," an engineer at mission control in Austin, Texas, called out as the team erupted in cheers.

CEO Jason Kim confirmed that the spacecraft was "stable and upright" – in contrast to the first private landing last February, which came down sideways.

"We're on the Moon!" Nicky Fox, associate administrator for NASA's Science Mission Directorate, rejoiced.

The first image from the lander revealed the rocky, pockmarked terrain it had to autonomously navigate in order to select its touchdown spot, having slowed down from thousands of miles per hour to just two mph.

Nicknamed "Ghost Riders in the Sky," the mission is part of a NASA-industry partnership aimed at reducing costs and supporting Artemis, the program designed to return astronauts to the Moon.

The golden lander, about the size of a hippo, launched on January 15 on a SpaceX Falcon 9 rocket, capturing stunning footage of Earth and the Moon along its 2.8 million-mile journey.

It shared a ride with a Japanese company's lander set to attempt a landing in May.

Blue Ghost carries 10 instruments, including a lunar soil analyzer, a radiation-tolerant computer and an experiment testing the feasibility of using the existing global satellite navigation system to navigate the Moon.

Designed to operate for a full lunar day (14 Earth days), Blue Ghost is expected to capture high-definition imagery of a total eclipse on March 14, when Earth blocks the Sun from the Moon's horizon.

On March 16, it will record a lunar sunset, offering insights into how dust levitates above the surface under solar influence, creating the mysterious lunar horizon glow first documented by Apollo astronaut Eugene Cernan.

Blue Ghost's arrival will be followed on March 6 by fellow Texas company Intuitive Machines' IM-2 mission, featuring its lander Athena.

In February 2024, Intuitive Machines became the first private company to achieve a soft lunar landing – also the first US landing since the crewed Apollo 17 mission of 1972.

However, the success was tempered by a mishap: the lander came down too fast and tipped over on impact, leaving it unable to generate enough solar power and cutting the mission short.

This time, the company says it has made key improvements to the hexagonal-shaped lander, which has a taller, slimmer profile than Blue Ghost, and is around the height of an adult giraffe.

Athena launched on Wednesday aboard a SpaceX rocket, taking a more direct route toward Mons Mouton, the southernmost lunar landing site ever attempted.

Its payloads include three rovers, a drill to search for ice and the star of the show: a first-of-its-kind hopping drone designed to explore the Moon's rugged terrain.
