FULL STORY ======================================================================

SpaceX is set to fly not one but two lunar landers to the Moon on the same mission. A Falcon 9 is scheduled to launch during an instantaneous window on Wednesday, Jan. 15, at 1:11 AM EST (06:11 UTC) from Launch Complex 39A (LC-39A) at the Kennedy Space Center in Florida, with Firefly Aerospaces Blue Ghost and ispaces HAKUTO-R M2 Resilience landers aboard, bound for different parts of the lunar surface.

The Falcon booster, B1085, will fly on a southeast trajectory out of the
Cape. The two lunar landers will be sent on different trajectories to the Moon, and the booster will land on the Just Read the Instructions droneship. B1085 started its career with the Starlink 10-5 mission and has flown the Crew-9, Starlink 6-77, and GPS III-7 missions. This flight, the eighth Falcon 9 launch of 2025, will be the first time two lander spacecraft have launched to the Moon on the same rocket.





Fireflys Blue Ghost lander

Firefly Aerospace developed the Blue Ghost lander to fly robotic missions to the lunar surface in response to NASAs Commercial Lunar Payload Services (CLPS) program. For its first CLPS mission, Blue Ghost is tasked with flying
a science mission to Mare Crisium, an ancient volcanic basin on the near side of the Moon.

The Blue Ghost lander, named after a rare firefly species found in the southeast United States, was designed to carry experiments, including rovers, to the lunar surface. The Blue Ghost lander masses 150 kg, while a transfer vehicle mated to the lander would increase the combination mass to 2,700 kg.

The box-shaped lander is two meters tall and three and a half meters in diameter, with the body covered in golden-colored insulation to protect it against the temperature extremes found on the lunar surface and in space.

Blue Ghosts main engine will use liquid hypergolic propellants, providing 1,000 newtons of thrust for lunar orbit insertion and the braking burn before landing. The lander is also equipped with 12 cold gas attitude control thrusters and eight Spectre reaction control system thrusters, which also use hypergolic propellants. Together, these thrusters provide 1,600 newtons of thrust for orientation and use during the soft landing process.

Blue Ghost is equipped with one X-band and three S-band antennas for communications, allowing high-definition video and data to be downlinked to Fireflys mission operations center in Texas. The lander will also use two navigation cameras to determine the safest landing site and identify nearby hazards on the surface.

Blue Ghosts body has three decks, with the top deck providing views of the
sky above the lander. The middle deck has mounting options for rovers, while the bottom deck has access to the lunar surface. The landers body extensively uses composite materials, with 49 struts used to provide a strong yet lightweight framework. The landers legs are also made of composite material and feature a crush core honeycomb to absorb impacts during touchdown. The legs are equipped with contact sensors to trigger engine shutdown after landing. Infographic with various milestones of Blue Ghosts first mission. (Credit: Firefly Aerospace)

Blue Ghost Mission 1: Ghost Riders In The Sky

The Ghost Riders In the Sky mission is Fireflys first lunar landing mission and its first CLPS mission for NASA. Mission 1 will carry 10 experiments to the surface, with a landing site near Mons Latreille, within the Mare Crisium volcanic basin, at 18.56 degrees north and 61.81 degrees east.

Although future Blue Ghost flights are planned to use Fireflys upcoming
Medium Launch Vehicle (MLV) rocket, the company booked Mission 1 on a SpaceX Falcon 9. MLV is set to make its first flight no earlier than 2026. The existing Firefly Alpha rocket does not have the payload or performance capability to fly Blue Ghost to the Moon.

Mission 1s journey to the Moons surface is scheduled to take up to 45 days, with the time in transit being used to conduct health checks on all systems and initial payload operations. The journey begins with a launch during a six-day window starting on Jan. 15, and system checkouts will start during an eight-hour commissioning process after lander separation from Falcon 9s
second stage. Infographic of Blue Ghosts landing sequence. (Credit: Firefly Aerospace)

The Mission 1 lander is scheduled to spend 25 days in Earth orbit before its trans-lunar injection burn and four-day transit to the Moon. After lunar
orbit insertion, the spacecraft will orbit the Moon for 16 days before its one-hour descent and landing process. An on-time liftoff on Jan. 15 will see the lander reach lunar orbit in mid-February and land early in the first week of March.

The lander is set to spend one lunar day (14 Earth days) operating on the surface, including a few hours during lunar night. If all goes as planned,
the ten experiments onboard will work on the lunar surface during this time. Various NASA centers, universities, and corporations sponsor these experiments.

The Lunar Environment heliospheric X-ray Imager (LEXI) is designed to observe the solar wind and its interaction with Earths magnetic field. Its vantage point will allow it to observe and provide the first global images of the
edge of Earths magnetic field. LEXI is sponsored by Boston University, Johns Hopkins University, and NASAs Goddard Space Flight Center (GSFC). The LEXI instrument being packed at Boston University. (Credit: Michael Spencer/Boston University)

GSFC also sponsors the Lunar GNSS Receiver Experiment (LuGRE), which is being conducted in cooperation with the Italian Space Agency. LuGRE is designed to receive and track GPS and Galileo signals during Blue Ghosts flight to the Moon and after landing on the lunar surface. This experiment may lead to the use of Global Navigation Satellite System navigation and timing signals
during lunar missions.

NASAs Langley Research Center has developed the Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) experiment. This instrument uses stereo imaging to observe rocket plumes from Blue Ghosts thrusters on the lunar regolith during landing. The high-resolution stereo images are intended to help measure lunar regolith erosion during landing events, which could become important as larger payloads are landed.

The Electrodynamic Dust Shield (EDS), developed at NASAs Kennedy Space
Center, uses electric fields to move dust and to prevent dust buildup on surfaces. The EDS, which does not have moving parts, will be demonstrated for the first time on the lunar surface. Future applications include
self-cleaning thermal radiators and glass surfaces, as dust accumulation becomes problematic for lunar and Martian missions.

Honeybee Robotics and Blue Origin have collaborated on two experiments for this mission. The Lunar PlanetVac is testing a lunar sample retrieval technology based on gas jets rather than robotic arms, while the Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity will drill
up to two to three meters below the lunar surface to measure heat flow.

The University of Marylands Next Generation Lunar Retroreflector is designed to allow for sub-millimeter range measurements of the Earths distance to the Moon, improving on Apollo-era measurements. Aegis Aerospace developed the Regolith Adherence Characterization instrument, which will expose various materials to the lunar regolith to measure its effects. The Intuitive

Finally, Montana State Universitys Radiation Tolerant Computer, already
tested in low-Earth orbit, will be tested as it passes through the Van Allen belts. Further tests will occur in the space between Earth and the Moon and
on the lunar surface. For Mission 1, the total dry mass of the lander and its payloads is 490 kg, while the total mission mass, including propellants, is 1,517 kg.

The Ghost Riders In The Sky mission aims to become the first United States lunar lander to successfully conduct a nominal, upright landing on the Moons surface since the December 1972 Apollo 17 mission. Two previous CLPS missions failed to do this: Astrobotics Peregrine Mission One did not reach the Moon, and Intuitive Machines IM-1 broke a landing leg and tipped 30 degrees, though it otherwise had a successful mission on the lunar surface.

HAKUTO-R

The Japanese company ispace developed the HAKUTO-R lander to fly payloads to the lunar surface as part of its business plan to sell transportation and other services related to the Moon. The company was a spinoff of engineer Andrew Bartons effort to win the Google Lunar X Prize, with Japanese members of Bartons White Label Space continuing an effort to land a private mission
to the Moon.

Hakuto is Japanese for white rabbit, with the R in the landers name standing for reboot. Massing around 1,000 kg, the lander is a boxy structure sporting fixed landing legs. It is just over two meters tall and two and a half meters wide, and its dry mass (without fuel) is 340 kg. It is designed to house various payloads, including a micro rover.

HAKUTO-Rs first mission, Mission 1, was the companys first effort to land on the Moon and the first Japanese spacecraft to attempt a lunar landing.
Mission 1 was launched successfully aboard a Falcon 9 on Dec. 11, 2022, and the spacecraft reached lunar orbit in March 2023 after taking a fuel-conserving route to Earths natural satellite.

Mission 1 attempted to land at Atlas Crater in the Mare Frigoris basin on the lunar near side on April 25, 2023, but failed after the onboard computer incorrectly marked altimeter data as faulty and ignored it. The lander
hovered five kilometers over the surface before running out of fuel near
Atlas Crater.

Mission 1 was the first Japanese lander to attempt a soft landing on the
lunar surface. The SLIM mission, developed by the Japan Aerospace Exploration Agency, successfully soft-landed on the Moon on Jan. 19, 2024, though it tipped on its nose during the landing. This mission made Japan the fifth nation to land a spacecraft on the Moon.

HAKUTO-R Mission 2

After Mission 1s failure, ispace worked to determine the cause of the failure and to refine its lander systems to prevent a recurrence. The company then started building a new HAKUTO-R lander named Resilience shortly after. Infographic of the HAKUTO-R Mission 2. (Credit: space)

Resilience is scheduled to start communicating with the ground within hours of its launch and to conduct its first orbital control maneuver within one to two days after it reaches space. The lander will take a similar low-energy trajectory to the Moon that Mission 1 used, conducting a flyby of the Moon
one month after launch.

The lander is scheduled to reach lunar orbit and attempt its landing around four to five months after its launch. Mission 2s landing site, like Mission 1s, is in the Mare Frigoris volcanic basin on the lunar near side, south of the lunar north polar region. The specific landing site is at 60.5 degrees north latitude and 4.6 degrees west longitude, in the middle of the basin, allowing for continuous communications with Earth.

Resilience is carrying a five-kilogram micro rover called Tenacious. This rover was designed and built by ispace in its Luxembourg facilities, and the Luxembourg Space Agency co-funded it. The Luxembourg National Space
Programme, LuxIMPULSE, received funding from a European Space Agency
contract. Infographic showing the TENACIOUS rover and its objectives.

NASA is also involved in Mission 2, as the rover contains a soil scoop to collect lunar regolith. Ownership of this regolith will be transferred to
NASA in situ. The rover also contains an artwork by Swedish artist Mikael Genberg called Moonhouse. The lander itself will take the micro rover and three other experiments to the surface along with a commemorative plaque.

Takasago Thermal Engineering Company developed water electrolyzer equipment
to fly on the lander, while the Euglena Company is flying a self-contained module for food production experiments. The National Central University of Taiwan is flying a deep space radiation probe, and Bandai Namco is flying a Charter of the Universal Century commemorative plaque.

Mission 2s motto is Never Quit the Lunar Quest, and ispace is planning additional landing missions to the Moon with greater frequency in the coming years, starting with Mission 3. Firefly intends to fly Blue Ghost missions regularly, with three CLPS task orders for landing missions already planned. The second Blue Ghost mission, scheduled for 2026, is set to land on the far side of the Moon, while the third Blue Ghost flight, in 2028, will land in
the Gruithuisen Domes region. Artists impression of the Firefly Blue Ghost lander and Elytra space tug during a future mission. (Credit: Firefly Aerospace)

As the commercial sector expands its robotic lunar landing activities in cooperation with government agencies, it faces technical and budgetary challenges. The canceled VIPER rover has been offered to the commercial sector, while companies that have flown missions to the Moon are learning
from the technical issues encountered by their spacecraft.

Firefly is hoping to succeed with its first-ever lunar mission, while ispace is making another attempt to land on the lunar surface. Their success or failure likely will impact future landing timelines for the companies and the timely availability of transportation services to the lunar surface for space agencies, research institutes, and corporations eager to send payloads to the Moon.
