Bringing Deep Space Missions Within Reach for Small Spacecraft Open
There is growing interest in using small spacecraft for science and exploration beyond low Earth orbit, but these missions have been constrained to fly as secondary payloads on rideshare missions that launch infrequently and on less-than-i…

Uncovering the wider impact of COVID-19 measures on the lives of children with complex care needs and their families: A mixed-methods study protocol Open
Existing barriers to care were exacerbated by the development and implementation of necessary public health restrictions during the COVID-19 pandemic. Children with complex care needs and their families represent a small portion of the pae…

Quantity and Quality: Scaling Small Business for Large Constellations Open
In 2018, Sinclair Interplanetary accepted an order constituting 40 star trackers and 80 reaction wheels, an order three times larger than had been received previously. Moreover, the delivery cadence was three times faster (12 units per mon…

Characterization of Chromatic Effects in Small Star Trackers Open
This paper explores how star color affects the design, calibration, and operation of star trackers. We develop a series of tools that characterize the chromatic performance of a star tracker and suggest how this information can be used in …
