ispace RESILIENCE Lunar Lander Successfully
Achieves Testing Milestone in Preparation for Mission 2All Testing Success Criteria & Qualifications AttainedTOKYO – June 27, 2024 – ispace, inc. (ispace)(TOKYO: 9348), a global lunar exploration company,
announced today that the flight model of its HAKUTO-R Mission 2 RESILIENCE lunar lander has
successfully completed thermal vacuum testing and remains on schedule for a Winter 2024
launch.

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 wasassembled 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 thatRESILIENCE collected during the ten-day testing regime. The results will allow engineers tooptimize 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 toexperience 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 operationof power systems, guidance, navigation and control (GNC) equipment, radio communications, andthermal 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.
“Lessons learned” obtained during Mission 1 pre-launch testing processes as well as actual flightdata were applied to the current testing operations to optimize efficiency and ensure more
rigorous testing of the lander systems.
“I am grateful for the efforts of ispace’s employees as the RESILIENCE lunar lander has achieved
another significant testing milestone in preparation for Mission 2,” said Takeshi Hakamada,Founder and CEO of ispace. “Conducting multiple missions in relatively short intervals has
improved the maturity of our team and the technology itself. We are dedicated to mission successand will continue to work towards realizing our vision of high-frequency, low-cost lunar
transportation services.”

“The successful completion of the thermal vacuum test for Mission 2 was a great achievement. I
am proud of the efforts of the team involved in this operation by improving the process based on
our experience from Mission 1 and the lander performed well, as we expected,” said Ryo Ujiie,
CTO of ispace. “The RESILIENCE lander is quickly moving towards final preparations for launch
and we are pleased with progress.”
Mission 2, ispace’s second lunar exploration mission, is expected to launch on a SpaceX Falcon 9
rocket from Cape Canaveral, Fla. RESILIENCE will deliver commercial and scientific equipment tothe lunar surface and is expected to contribute to the NASA-led Artemis program. In addition toits commercial payloads, the mission will include a micro rover that will deploy from the lunar
lander and conduct surface exploration including the collection of lunar regolith.
In December 2020, ispace EUROPE was selected by NASA to acquire regolith from the lunar
surface to be purchased by the space agency. In furtherance of this effort, a shovel developed by
Epiroc AB, a leading productivity and sustainability partner for the mining and infrastructureindustries, and a corporate partner participating in the HAKUTO-R program, has been delivered
and mounted on the micro rover. Once on the lunar surface, ispace operators plan to use theshovel to collect a sample of lunar regolith and photograph the collection with the camera
mounted on the rover.
ispace is leveraging its global presence through its three business units in Japan, the U.S., andLuxembourg, for the simultaneous development of Mission 2 and Mission 3. Mission 2 is plannedfor 2024, led by the ispace Japan entity, and Mission 3 in 2026, led by the ispace U.S. entity.
Mission 6, which will utilize the Series 3 lander, being designed in Japan, is scheduled to belaunched by 2027.
