The safe landing and successful testing of the Perseverance rover will now lead to the testing and deployment of the Ingenuity helicopter. At the time of writing, the engineers behind Perseverance were identifying a flat area where Ingenuity can operate, in a first for powered flight on another planet. The typical 20-minute time lag for control signals to Mars makes remote control of a helicopter impractical, so autonomous operation has been designed in from the start. Ingenuity’s engineers are planning autonomous missions for it, to photograph and explore more of the Martian surface. The flight time for Ingenuity is only 90 seconds from its lithium-ion battery pack, highlighting the challenge of the energy density of battery packs for unmanned systems. We explore the challenges and opportunities of this energy density in more detail on page 34. This move to autonomous operation is reflected in the latest design by Hyundai Motors (see Platform one, starting on page 6). Its Tiger-X is the company’s first unmanned space system design, opening up new locomotion options with articulated legs to cope with challenging terrain. The challenge of flight time is also one that drives Volocopter’s CTO Dr Arnaud Coville. Our interview with him, on page 18, looks at his work on battery-powered passenger aircraft and large UAVs, and the rapid progression of the technology.
