It's a beautiful rendering of a spacecraft in Earth orbit
AOSO Canceled mis-labeled "OSO-1"https://rammb.cira.colostate.edu/dev/hillger/OSO_reference.htmI found a site maintained by Don Hillger US and Garry Toth Quebec Canada.

From there: https://rammb.cira.colostate.edu/dev/hillger/AOSO_image2.jpgAttached below. Pretty clearly this is a photo of the painting, based on the location of the stars in the background.
Do we have any info at all about why they differ (different proposals, different stages in the process, …) ?
February 28th, 1963:GSFC plans for second-generation OSO satellite-known as Advanced Orbiting Solar Observatory, or Helios-were outlined at Philadelphia technical meeting by Goddard's AOSO Project Manager A. J. Cervenka. AOSO would be designed to have a pointing accuracy of 5 seconds of arc and 70 percent overall systems reliability, Cervenka said. October 22, 1963:GSFC began negotiations with Republic Aviation Corp. for Phase I dontract for Advanced Orbiting Solar Observatory (AOSO). AOSO would be launched into a 300-mile near-polar orbit for observations of x-rays, gamma rays, and ultraviolet emissions of the sun. Phase I calls for oneyear development of systems engineering and detailed design of the satellite.
For the Advanced Orbiting SoJar Observatory (Helios), the initial planning was done in the Spring of 1961-with the first launch, hopefully, in 1966.[...]The proposed Advanced Orbiting Solar Observatory (Figure 3-4) is a spacecraft about 10 feet long and 40 inches in diameter, weighing about 1000 pounds. Of this weight, 250 pounds is reserved for experiments occupying a cubic volume of more than 45 cubic feet. It will be possible to fly a 20-inch telescope, 10 feet long.

Also fascinated to see that Republic apparently beat STL and Ball Brothers who had earlier done the other study contracts for Goddard on AOSO, unless the latter two weren't interested in bidding for some reason.
