The moon will be a busy place this year. There are three robotic spacecraft in space right now that are aiming to set down on the moon\u2019s surface.<\/p>\n
The first of those to arrive \u2014 the Blue Ghost lunar lander, built by Firefly Aerospace of Cedar Park, Texas \u2014 will attempt to land early Sunday.<\/p>\n
The landing is scheduled for 3:45 a.m. Eastern time on March 2. Firefly will begin live coverage of the landing at 2:20 a.m. from its YouTube channel.<\/p>\n
This mission is headed to Mare Crisium, a flat plain formed from lava that filled and hardened inside a 345-mile-wide crater carved out by an ancient asteroid impact. Mare Crisium is in the northeast quadrant of the near side of the moon.<\/p>\n<\/div>\n<\/div>\n
The lander is carrying a variety of scientific and experimental payloads to the lunar surface, including 10 for NASA. Those include a drill to measure the flow of heat from the moon\u2019s interior to the surface, an electrodynamic dust shield to clean off glass and radiator surfaces, and an X-ray camera.<\/p>\n
That cargo is part of the Commercial Lunar Payload Service, or CLPS, which aims to put NASA equipment on the moon at a cheaper price than if NASA built its own lunar lander. The agency will pay Firefly $101.5 million if all 10 payloads reach the lunar surface, and a bit less if the mission does not fully succeed.<\/p>\n
Blue Ghost is the third CLPS mission to launch to the moon. The first, in 2024, from Astrobotic of Pittsburgh, failed after launching. The second, by Intuitive Machines of Houston last year, reached the moon but tipped over.<\/p>\n<\/div>\n<\/div>\n
The physics of getting to a certain place in the solar system at a certain time does not always match when people will be awake to watch. The Blue Ghost lander spacecraft gets its power from solar panels, and thus the mission is aiming to land soon after the dawn of a new lunar day. And to get to Mare Crisium on March 2, the landing time turns out to be 3:45 a.m.<\/p>\n<\/div>\n<\/div>\n
\u201cThat\u2019s just when that happens,\u201d said Ray Allensworth, the program manager for Blue Ghost at Firefly.<\/p>\n
The mission is to last about 14 Earth days until lunar sunset.<\/p>\n
Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft\u2019s systems. It then fired its engine on a four-day journey toward the moon, entering orbit on Feb. 13. The spacecraft\u2019s cameras have recorded close-up views of the moon\u2019s cratered surface.<\/p>\n
A few small glitches have come up along the way, but no major malfunctions. Mostly, the mission controllers made adjustments as they learned how the spacecraft behaved in the space environment.<\/p>\n
\u201cThermal alarms might go off,\u201d Ms. Allensworth said. \u201cThings are getting a little hotter than planned, a little colder than planned on the vehicle. You want to look at that data and see is it actually OK.\u201d<\/p>\n
On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload. That turned out to be the Blue Ghost launch.<\/p>\n<\/div>\n<\/div>\n
Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.<\/p>\n<\/div>\n<\/div>\n
