More people on the Moon might be pie in the sky for now, but it looks probable that astronauts will be sent to both an asteroid (in the 2020s) and to Mars (in the 2030s). That can only happen if new spacesuits are developed.
Why? Those used on the ISS, and by all astronauts, were designed for weightless environments, and while the Moon has just 16% the gravity of Earth, Mars has 62%. Moving around, bending and flexing suddenly becomes not only possible, but critical for survival. Cue Nasa's Z-2 spacesuits, which allow just that, as well as using e-Ink, self-healing polymers and memory foam, and featuring sensors galore.
