To assess the quality and resolution of protein crystals grown in space using the new technology.
To enable detailed atomic structure analysis and comparison with terrestrial crystal growth.

Main Methods:

Utilized the 'Organ.Aut' bioassembler for in-space protein crystallization.
Grew protein crystals under microgravity conditions.
Analyzed crystal quality and diffraction data.

Main Results:

The 'Organ.Aut' bioassembler successfully produced highly ordered protein crystals in space.
Crystals diffracted to a true-atomic resolution of approximately 1 Å.
Atomic structures were examined in detail, allowing for comparison with Earth-grown crystals.

Conclusions:

The 'Organ.Aut' bioassembler is a viable and promising tool for advancing protein crystallization in space.
This technology facilitates high-resolution structural biology studies.
In-space protein crystallization with precise control is achievable and beneficial.
