Nature – first prize, stories. Pandemic Pigeons – A Love Story. The photographer’s daughter, Merel, cowers after Dollie flies past and perches on the balcony before entering the house in Vlaardingen in the Netherlands on 6 April 2020. “She’s still frightened when Dollie suddenly lands on the balcony railing. I hide my smile behind the camera, as I try to comfort her by saying they won’t hurt you. “I thought he was going to attack me”, she replies. As the nesting pigeons keep coming back to our place, slowly my girls have started to appreciate them – perhaps not as much as I do, but it’s a start”. (Photo by Jasper Doest/World Press Photo 2021)

“The Space Launch System, or SLS, is a Shuttle-Derived heavy launch vehicle being designed by NASA, following the cancellation of the Constellation Program, to replace the Space Shuttle after its retirement. The NASA Authorization Act of 2010 envisions the transformation of the Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo. It is to be upgraded over time with more powerful versions. The proposed SLS is visually similar to the legacy Saturn V booster and in particular the proposed, two-stage, Saturn INT-20”. – Wikipedia
