Watch this video first: The Earth seen during suborbital flight (November 2015).
Flight Opportunities is a NASA program established late 2010 to support the then-emerging commercial suborbital launch industry. Today it supports commercial suborbital, small orbital launch vehicle technology development, and materials testing on the external side of the International Space Station (read more here).
The program's Annual Reports give a good overview of the program. For the first five years (2011-2015), the budget was mandated by Congress at ~$10 million. It was raised to ~$15 million in FY2017 to enable the newstart of supporting the emerging commercial small launch vehicle industry (e.g. Virgin Orbit, Vector Space, and others). Additional photos from the various suborbital flight campaigns are available on Flickr.
