ispace Aims for Hakuto-R Moon Touchdown June 6; Third Company to Attempt a Lunar Landing in 2025

The anticipated landing of ispace Hakuto-R Resilience is set for 04:24 on June 6 (Japan Standard Time). There will be livestreamed events for the landing sequence. This second attempt by ispace comes just over 2 years after the first was made in April 2023. The dry mass of Resilience is 340 kg, fully fueled with its payloads it weighs nearly 1,000 kg. Helping to guide the landing at Mare Frigoris 60.5°N 4.6°W are the main landing thruster and six assist thrusters. Primary payloads aboard the lander are a water electrolyzer experiment provided by Takasago Thermal Engineering Co, an algae-based food production module by Euglena Co, a 14-ounce Deep Space Radiation Probe by Taiwan National Central University, and the 5-kg, 26-cm tall Tenacious rover that carries 3D printed “Moonhouse” by artist Mikael Genberg. There is also a UNESCO memory disk made of nickel and nano-engraved (holding the equivalent of 4GB of data) and a commemorative plaque created by Bandai Namco Research Institute based on the media franchise Gundam. The rover will shovel regolith and use an HD camera to photograph the collected sample, fulfilling the first part of the US$5,000 NASA Lunar Regolith Transfer Contract. Power is provided by body-mounted solar panels charging a lithium-ion battery (350 W peak). Uplink and downlink communications will occur via X-band. Other landers potentially launching this year are Intuitive Machines IM-3 mission, Astrobotic Griffin with Astrolab FLIP rover, and Blue Origin Blue Moon. (Image credits: ispace)
