NASA supports small sensors with 3D footprint for planar rovers



Current sensor manufacturing methods include building one sensor at a time and then combining it with other elements. They are relatively bulky and inefficient and tend to rely on mass spectrometers that have problems with the discovery of materials such as methane and water. This new 3D approach prints all sensors and some of the patterns on a substrate, and can detect those subtle substances. If it works as planned, it can help future ruvers find places that support (or once maintained) life. They can also be used as safety systems that warn of changes in air conditions in spacecraft and habitats. No matter how small this technology is, it can be vital for long-term exploration of the cosmos.
