ESA Ground Stations to Support HAKUTO-R Commercial Moon Landing
ESA is readying ground stations to support Japan's HAKUTO-R lunar exploration program, which will mark the first commercial moon landing. The launch of the mission has been delayed due to an issue with a SpaceX Falcon 9 booster.
“The mission will also provide ESA’s ground station teams with valuable experience for upcoming ESA and partner missions going to the Moon, such as Lunar Pathfinder and those of ESA’s Moonlight initiative.”

Mission 1, the first mission of the HAKUTO-R lunar exploration program, will be launched into a low-energy transfer orbit by a SpaceX Falcon 9 rocket to the Moon. The journey will take three to five months and see the spacecraft venture out to deep space and back again. Once on the Moon, it will conduct a host of experiments in cooperation with various commercial and agency entities on Earth.
“This is exactly the future of lunar exploration that we are working towards,” said Rolf Densing, ESA Director of Operations.
“The mission will also provide ESA’s ground station teams with valuable experience for upcoming ESA and partner missions going to the Moon, such as Lunar Pathfinder and those of ESA’s Moonlight initiative.”
“We are pleased to be working with ESA and utilizing their extensive tracking station network in support of our Mission 1 operations,” said Takeshi Hakamada, Founder & CEO of ispace. “I believe this kind of international collaboration is vital to building a robust cislunar economy, as it opens the doors for companies like ours to contribute expertise to the future of commercialized space.”
ESA Ground Stations will Provide a Crucial Link for HAKUTO-R Mission
Following launch and separation, the spacecraft will be operated from the HAKUTO-R Mission Control Center in central Tokyo, Japan. The Center will monitor the lunar lander’s vital signs – its attitude, temperature, and other conditions – send commands to the spacecraft and receive the data gathered by the lander’s various instruments and experiments during transit to the Moon and during their time on the lunar surface.
But how will mission controllers get their commands to the spacecraft and its experiments' data back to Earth from deep space and eventually from the Moon’s surface? That’s where ESA comes in.
ESA's tracking station network – Estrack – is a global system of ground stations providing links between satellites across the Solar System and ESA’s ESOC mission control center in Darmstadt, Germany. Our tracking stations enable satellite operators to communicate with their spacecraft, transmit commands and receive scientific data and spacecraft status information.
The lunar lander will be supported by ESA’s largest deep space antennas – three 35-meter (≈115-foot) dishes located in New Norcia, Western Australia, Cebreros, Spain, and Malargüe, Argentina. Two smaller ESA antennas located in Kourou, French Guiana, and New Norcia will also provide support, as will the commercial Goonhilly Earth Station in the UK, as part of the ‘Estrack extended network’.
ESA’s first contact with the lander after launch – known as ‘acquisition of signal’ – will take place over the New Norcia station in Australia. This crucial moment allows ispace to check that the lander is healthy, survived the rigors of launch, and is on the right path. The Estrack and Goonhilly stations will then follow the lander as it ventures out into deep space and back again on a sweeping trajectory designed to reduce the amount of fuel the spacecraft needs to carry.
It will reach as far as 1.5 million km (≈932,000 miles) from Earth at its farthest point – roughly four times the distance between Earth and the Moon. The spacecraft will enter lunar orbit for around one month before the whole craft descends to perform lunar landing.
Surface operations will last for approximately two weeks, with the landing timed as close to the lunar dawn at the landing site as possible, in order to maximize mission time.
ESA’s stations will again be on hand to receive vital data during the descent and confirm a successful landing. During these two weeks, science data will stream down from the Moon to the experiment teams on Earth via ESA’s antennas.
