ANISE: Modern rewrite of NASA's SPICE toolkit (TRL-9)

-

Landed Firefly Blue Ghost on the Moon in March 2025

-

NASA's SPICE toolkit marked a significant advancement in space mission analysis. However, its FORTRAN foundation, complex API, and incompatibility with multi-threaded applications limits its scope. ANISE is a complete rewrite of SPICE, offering a user-friendly API and bindings to Rust, C++, and Python. Designed with thread- and memory-safety as a core feature from the outset, ANISE is a significant step forward in space mission software.

+

Validated SPICE Replacement

+

ANISE

+

Validated and expanded SPICE replacement via ANISE with multi-thread and no race conditions. It is up to 500x faster than Ansys STK. Designed with thread- and memory-safety as a core feature from the outset, ANISE landed Firefly Blue Ghost on the Moon in March 2025.

Hifitime: Precision Time Management

-

Advanced library for time systems conversions (UTC, ET, TAI, ...)

-

Space applications require high fidelity time compution, including time systems that ignore the relativistic effects due to the gravity of the Earth. Hifitime is formally verified, thoroughly tested, and works on desktop, web assembly, and bare-metal platforms. Hifitime is arguably the most precise time management library in the world and trusted by institutions that require nanosecond precision.

+

Precision Time Management

+

Hifitime

+

An overflow-safe, high-performance datetime library providing leap-second-correct nanosecond precision across UTC, GPST, and relativistic time-scales. Flight-proven in lunar and deep-space missions, it works on desktop, web assembly, and bare-metal platforms.
