A small uncrewed spacecraft is buzzing the moon, with below two weeks remaining earlier than its daring try to land on the lunar floor.
Firefly Aerospace, a non-public firm employed by NASA to ship science experiments to the moon, simply achieved one other milestone on its mission. On Tuesday, its Blue Ghost lander, named after an unique kind of firefly, relit its engine in house to decrease its egg-shaped lunar orbit. The burn, which lasted three minutes and 18 seconds, introduced the lander inside 75 miles of the bottom.
However the true deal with was the footage beamed again to mission management of the moon’s mysterious far aspect, solely seen firsthand by 24 folks, all Apollo astronauts within the Sixties and Seventies. The video, posted farther down on this story, captures closely cratered terrain, dashing away because the spacecraft flies above.
Firefly’s Blue Ghost lander is carrying 10 NASA devices to the floor of the moon. It can try to the touch down on March 2, 2025.

The far aspect is the hemisphere of the moon dealing with away from Earth. As a result of folks by no means see it from our perch on Earth, that portion was as soon as dubbed “the dark side.” The complicated misnomer has led many to incorrectly assume the far aspect is shrouded in darkness. In actuality, it receives simply as a lot mild because the close to aspect.
It takes a couple of month for the moon, some 250,000 miles away, to orbit Earth. It additionally takes the identical period of time for the moon to make one full rotation on its axis. This coincidence is why Earthlings all the time see the identical lunar aspect.
Previous to house exploration, many speculated the far aspect was an ominous area, a fantasy perpetuated by Pink Floyd’s trippy “Dark Side of the Moon” album in 1973.
Certainly the far aspect remained an enigma to people, however solely till October 1959. That is when the Soviet house program swung the Luna 3 probe across the moon. The spacecraft returned a number of grainy photographs that exposed a curiously completely different floor than that on the acquainted close to aspect, with vastly much less splotches referred to as maria, darkish areas shaped when meteoroids slammed into the moon and prompted lava to emerge. The far aspect, then again, is blanketed in additional craters of varied sizes and depths.
Mashable Gentle Pace
China turned the primary — and, thus far, solely — nation to land an uncrewed spacecraft on the far aspect throughout its Chang’e-4 mission in 2019. The moon itself blocks communication between mission controllers on Earth and the far aspect. However in 2018, China put a communication relay satellite tv for pc in house about 40,000 miles past the moon that would alternate the indicators.
Firefly’s lander, initially scheduled to carry off in late 2024, is the primary NASA Business Lunar Payload Companies mission of the 12 months. This system has invested $2.6 billion in contracts with distributors from the personal sector to assist ship devices to the moon and ship again essential information.
Blue Ghost is carrying 10 devices for NASA, which has paid Firefly $101.5 million for the trip. The house company desires to see a common cadence of moon missions to arrange for astronaut-led Artemis expeditions in 2027 or later.
Mission management is concentrating on the Blue Ghost touchdown for 3:45 a.m. ET on Sunday, March 2. If all goes as deliberate, the spacecraft will discover its struts on Mare Crisium, a plain made out of an historical hardened lava circulation. This volcanic characteristic just isn’t on the far aspect, however the northeast quadrant on the close to aspect of the moon. The touchdown website is predicted to offer insights into the lunar setting and check applied sciences for supporting future landings carrying astronauts.
That is the mission trajectory plan for Firefly Aerospace’s Blue Ghost lander.

Although there will not be any video of the spacecraft’s precise descent to the floor, NASA and Firefly intend to broadcast commentary for the occasion, beginning at 2:30 a.m. ET that morning.
“Our available bandwidth will be dedicated to critical descent operations during landing, so (we) will not be streaming live video during descent,” Firefly officers stated on X, previously referred to as Twitter.
Anybody who has tried it may possibly vouch that touchdown on the moon is onerous. The moon’s exosphere supplies nearly no drag to sluggish a spacecraft down because it approaches the bottom. Moreover, there are not any GPS techniques on the moon to assist information a craft to its touchdown spot. Then there’s the truth that every part is about six instances tippier on the moon.
A handful of house businesses all over the world have caught a touchdown, however thus far only one firm, Intuitive Machines, has made the robotic journey throughout lunar landing. Its craft landed sideways close to the moon’s south pole in February 2024, nonetheless managing to function from its awkward place.
