DENVER, Colo. – ispace technologies U.S., inc. (ispace-U.S.), an American lunar explorationcompany, today announced the official launch of a new data relay service enabled by two relay
satellites that are expected to be deployed during ispace-U.S.’s Mission 3 scheduled in 2026.
The launch service is expected to be provided by SpaceX. The details were released at theLunar Surface Innovation Consortium 2024 Spring Meeting hosted by the Johns Hopkins
Applied Physics Laboratory.
The two lunar relay satellites will enable communications to and from the Earth, and the APEX
1.0 lunar lander, which is expected to touch down in the Schrödinger Basin on the Lunar Far

Side, a large impact crater near the Moon’s South Pole. The lander is designed to support theDraper-led Commercial Lunar Payload Services Task Order CP-12 by delivering NASApayloads to the lunar surface for scientific investigations. The relay satellites will be deployed
into lunar orbit by the APEX 1.0 lunar lander prior to landing.
At the conclusion of the scientific investigations, the satellites will circularize into a High Circular
Polar Orbit (HCPO) with near-global coverage with linger points at the polar regions. For Lunar
South Pole landing sites, both relay satellites are expected to offer more than 70 percent
simultaneous visibility of the lunar surface and the Earth, providing potential data service users
with a significant opportunity to utilize such data.
The company expects that relay satellites, which are expected to stay in orbit for several years
and operate beyond ispace’s Mission 3, would enable and enhance future lunar missions byproviding data that complement information gathered by lunar surface or lunar orbital payloads,
as well as potentially contributing to improved edge processing and fusion of onboard or remote
payload data. RTX’s (NYSE: RTX)’s small satellite manufacturer and mission services
provider, Blue Canyon Technologies, will design and manufacture two Venus-classmicrosatellite buses that will serve as a platform carrying lunar communications relay
capabilities.
ispace-U.S. is currently in discussion with companies and organizations for payloadtransportation services to be provided on the APEX 1.0 lunar lander for Mission 3. ispace-U.S.
is engaging in conversations with potential customers who may wish to utilize the relay
satellite’s capability for a variety of purposes such as technology demonstrations, including
potential alternative Position, Navigation, and Timing (PNT) services.
The schedule for Mission 3 is as of April 2024 and is subject to change.

###About APEX 1.0 Lunar Lander
ispace’s APEX 1.0 lunar lander, designed to be one of the most capable lunar vehicles
available, serves as the company’s next-generation lander. The APEX 1.0 lander, designed andbuilt in the U.S., is expcted to have enhanced capabilities leveraging lessons learned from theprevious lander model, which was used for Mission 1. With a payload capacity of 300 kgs to thelunar surface, APEX 1.0 is designed to deliver ten times more payload to the lunar surface
compared to earlier ispace missions. ispace-U.S. plans to progressively increase the APEXseries payload capacity to meet evolving customer requirements, eventually reaching payload
capacity of 500 kg to the lunar surface. This highly capable design also provides APEX 1.0 withthe ability to transport orbital, stationery, and rover payloads to either the near or far side of theMoon. With advanced structural durability, reliability, and manufacturability, APEX 1.0 is
expected to make consistent quality and performance at scale possible.

About ispace technologies U.S.

ispace – U.S. is an American lunar exploration company providing transportation andinfrastructure capabilities from Earth to lunar orbit and the surface of the Moon for governmentand commercial customers. ispace believes that the utilization of lunar resources is the catalyst
to enabling human permanence and economic opportunity on and around the Moon and iscommitted to achieving this goal. The company’s U.S. headquarters serves as the central
location for the development of its APEX 1.0 lunar lander, which is being designed,
manufactured, and launched in the United States. In partnership with Draper, this lander will
deliver a suite of multiple NASA-sponsored science payloads to the lunar surface as part of theNASA Commercial Lunar Payload Services (CLPS) Initiative.
