Using body paint and a woodland like location, Gesine appears to have created a model to look just like a red panda, Dortmund, Germany, October, 2016. An artist brings animals to life using body paint and contorted models. At first glance, these images could be mistaken for portraits of wildlife in their natural habitat were created with paper and paint. However, they are actually the incredible works of illusion by talented body painter Gesine Marwedel, who paints models to creates realistic animals. (Photo by Gesine Marwedel/Barcroft Images)

The NASA Extreme Environment Mission Operations (NEEMO) 21 mission began on July 21 as an international crew of aquanauts splashed down to the undersea Aquarius Reef Base, located 62 feet below the surface of the Atlantic Ocean in the Florida Keys National Marine Sanctuary. The NEEMO 21 crew will perform research both inside and outside the habitat during a 16-day simulated space mission. During simulated spacewalks carried out underwater, they will evaluate tools and mission operation techniques that could be used in future space missions, including journeys to Mars.
