Abstract: An integrated ion thruster unit for a spacecraft can include a unit housing including a thrust face, and a plurality of tiles arranged in an array on the thrust face. Each of the tiles can include an emitter and an extractor configured to provide a reference voltage with respect to the emitter. The emitter can include a plurality of tips configured to emit ions in a thrust direction from an ionic liquid propellant in response to an applied voltage.

Abstract: The present disclosure provides compositions and methods for making and using a support (e.g., a sample slide) for sample analysis. The present disclosure also provides compositions, methods, and systems for processing a sample on the support for use in nucleic acid sequence detection.
