Prints of photos & usage rights for photos are available for most photos on this website. Some launch and mission photos, specifically, are either not available for sale or are public domain photos. For such images, I can direct you to the right source for free downloading of the image.
For prints, please email for a price list and let me know what photos and sizes you would like to purchase.
For photo usage, publications, editorial or commercial usage or any other medium, please be descriptive and include relevant information, such as which photos, how they will be used, when/for how long if applicable, and distribution or audience size. Thank you.
