the laboratory tests in 2014 [15]. However, there is no public information confirming the launch or success of a MOIRE space mission. A diffractive lens [7] is considered to be one of the imaging technologies for a \"Breakthrough Starshot\" interstellar picosatellite project [16]. More recent studies include a telescope based on a diffractive lens [17], an array of diffractive lenses [18], and a membrane diffractive lens [19; 20]. Despite this progress, none of these telescopes has been sent to space. The TOLIMAN space telescope with a diffraction pupil lens was announced in 2018 [21]. In this work, we discuss design decisions, image reconstruction, and the results of the first in-orbit experimental study of images produced by a 3U CubeSat nanosatellite with an ultra-lightweight remote sensing camera based on our harmonic diffractive lens designed from the ground up in our lab. This lens is significantly lighter and thinner than a conventional refractive lens of a similar focal length and aperture, as we described in our previous work [10] in more detail.
