and with an openable personalised helmet; often the episodes feature a recurring blooper: the astronaut's helmet is accidentally open. Gundam Spacesuits are commonly used in the Gundam anime media mix, but are often renamed to avoid confusion with space-use mobile suits. In the Universal Century timeline, spacesuits are called "normal suits"; the After Colony timeline calls them "astrosuit". Two types of spacesuit are frequently seen - as well as the more traditional bulky style, mobile suit pilots wear a thinner lighter suit, better designed for operating a mobile suit's controls. Gundam spacesuits often have a pouch full of adhesive strips, used to temporarily seal tears in the suit (as demonstrated in Mobile Suit Gundam) or cracks in the helmet (as demonstrated in Char's Counterattack). Perry Rhodan The German pulp science fiction series Perry Rhodan features a type of spacesuit known as a SERUN, for Semi-Reconstituent Recycling Unit. This suit contains advanced recycling systems that can provide the necessary oxygen, water, and food to keep the inhabitant alive for weeks. It also contains a sophisticated computerized medical treatment system, antigrav units for propulsion, and a generator for a defense screen. Gravity The 2013 film Gravity, by Alfonso Cuarón with Sandra Bullock and George Clooney, was both appreciated and criticized for its use of space suits. Besides objections to the unrestricted look of extravehicular activities was the lack of protective undergarments, displayed (not) by Bullock when she removed her suit—lacking critical items such as a liquid cooling and ventilation garment or socks. Interstellar In the 2014 film Interstellar, NASA uses futuristic spacesuits during the Lazarus missions and during Cooper and Brand's missions. Cooper also uses a black spacesuit at the film's end. Scorpion In the episode "The Old College Try", to survive in subzero temperatures near a quantum computer, Walter wears an A7L spacesuit from the Apollo program. Sylvester and Happy wears vintage spacesuits, too, but they are probably fictional (like the two characters themselves). The Martian In Andy Weir's 2011 novel The Martian, astronauts from the Ares missions use white spacesuits to walk on Mars' surface. The suits in the book are described as similar to the EMU suit. Movie adaptation Ridley Scott's 2015 adaptation of the novel features these suits: Ares III spacesuit Used by Watney during his period on Mars, this is a small orange and grey spacesuit, equipped with a GoPro-like suitcam, a vocal device which signals about
