Ispace’s Resilience lunar lander completes thermal vacuum testing
The Japanese startup Ispace announced late last week that its second lunar lander, formerly names Hakuto-R2 and now dubbed Resilience, has successfully completed thermal vacuum testing and is on schedule for a launch before the end of this year.
The testing was completed at the Japan Aerospace Exploration Agency (JAXA) Tsukuba Space Center in Tsukuba, Japan, where the agency operates a large testing facility. The flight model was assembled at the facility and all payloads or testing models were integrated into the lunar lander before testing began. All test success criteria were met; ispace engineers are now reviewing the detailed data that RESILIENCE collected during the ten-day testing regime. The results will allow engineers to optimize the spacecraft thermally for spaceflight as well as improve flight operation procedures.
Thermal vacuum testing is conducted in a large chamber that allows the lunar lander to experience conditions similar to what it will face during its journey through outer space including extreme temperatures in a vacuum environment. Initial test results indicated successful operation of power systems, guidance, navigation and control (GNC) equipment, radio communications, and thermal control of the lander while simulating an actual spaceflight. During testing in the chamber, ispace operators utillized the lander’s onboard radio to assess connections, send commands to, and receive telemetry from the lander, further simulating actual flight operations.
This lander will also carry a mini-rover, and will be launched by a Falcon 9 rocket. The company’s press materials don’t name a location for the lunar landing spot, though one must have been chosen. I suspect, as this mission is a precursor to Ispace’s first NASA lunar landing mission set for 2026, it will be sent to the same location as Ispace’s first Hakuto-R1 test mission, which got to within three miles but then crashed because sensors thought it was just above the surface and shut off the engines prematurely.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
