LEVITY IS ASTRAIT NOW!
Multipurpose satellite platform
Our small-satellite ESCI-MOON will redefine the market
We offer a universal and flexible platform for dedicated missions of small payloads up to the Moon. The platform can also act as a kickstage, transporting small satellites and offering deep space relay services at the target environment.
ESCI-MOON does not require a Moon-rocket, as it is a free-flying platform using electric propulsion and can be launched into GEO to reach the Moon within a year.

Nano-, Cube- and Microsats
Break the limits of the current transport infrastructure
By accommodating dedicated adapters and dispensers instead of a payload, ESCI-MOON acts as a kickstage to provide lunar access for SmallSats without the need for a rare and costly rideshare on a Moon-rocket AND already includes a deep-space communication relay system.

Addressable mission environments
In the wake of ongoing miniaturization in parallel to improving performance of space missions, Microlaunchers and GEO launch providers will enable ESCI-MOON to realize the future small satellite missions of endless possibilities.
ESCI-MOON is designed to make use of future flexible Small-Sat launch solutions – enabling it to start its missions in GEO.
Its own free-flying capability allows nimble, low-cost and long-term dedicated missions for commercial- and scientific missions: situational awareness, observation and support for already established activities in the GEO-region call for a ready-to-use platform like ESCI-MOON.
Starting in GEO, ESCI-MOON can assume any orbit between GEO and the Moon.
The environment beyond earth’s magnetic field is poorly explored. Since it is planned to freqently send out manned missions to the Moon which will cross this region on any journey, scientific examination and monitoring of the cislunar environment for hazard prediction becomes a significant mission type.
ESCI-MOON is designed to go Lunar!
Using the full potential of its electric propulsion system, it can spiral up to the Moon within a year after starting in GEO based on an optimized trajectory. Once captured by Moon’s gravity, reverse thrust allows precise targeting of any orbit down to 100km altitude.
ESCI-MOON’s design results in an alternative infrastructure for observation-, support-, navigational- and satellite transport missions as well as for technology demonstration of new components.
Thanks to the electric propulsion concept, demanding LEO missions can also be targeted with ESCI-MOON, enabling high maneuverability, frequent orbital transfers, de-orbiting from high orbits and a long mission duration even in low altitudes.
ESCI-MOON’s parabolic X-Band antenna and precise 3-axis pointing hereby allow high-fidelity Earth observation missions requiring high data downstream rates. This way also in LEO the potential of ESCI-MOON’s deep-space capabilities never remains unused.

A GLIMPSE INTO THE FUTURE
Demonstration mission to the Moon planned in 2026
Inspired by the SMART-1 mission (ESA 2004), ESCI-MOON’s demonstration mission will carry out a spiral transfer from GEO to the Moon. ASTRAIT will collaborate with scientific and commercial payload providers willing to support ASTRAIT with their payload(s) to prove concept, technology and applicability of the ESCI-MOON mission portfolio.
