TL;DR: In this paper, a star camera was designed, built, and flight-tested for pointing a pointed balloon-borne experiment at altitude around 40 km. The camera and lens are commercially available, off-the-shelf components, but require a custom-built baffle to reduce stray light, especially near the sunlit limb of the balloon.

TL;DR: The High Energy Replicated Optics to Explore the Sun (HEROES) mission is a collaborative effort between the NASA Marshall Space Flight Center and the Goddard Space Flight Centers to upgrade an existing payload, the HERO) balloon-borne telescope, to make unique scientific measurements of the Sun and astrophysical targets during the same flight as discussed by the authors.

TL;DR: The Deep Space Test-Bed (DSTB) as mentioned in this paper is designed to investigate the effects of galactic cosmic rays on crews and systems during missions to the Moon or Mars using high-altitude polar balloon flights.

TL;DR: The High Energy Replicated Optics to Explore the Sun (HEROES) project as mentioned in this paper was the first balloon-borne x-ray telescope to make observations of the Sun.
