NASA’s Perseverance Rover recently made a successful landing on Mars, embarking on a two-year mission to seek signs of ancient life and collect samples. Because Mars is extremely cold—nighttime temperatures can drop below -112 F—heaters are required to keep the rover’s battery system from freezing. Now, researchers reporting in ACS’ Nano Letters have 3D printed porous carbon aerogels for electrodes in ultralow-temperature supercapacitors, reducing heating needs for future space and polar missions.

A comparative analysis of degradation processes, failure modes and mechanisms in MnO2 and polymer technology tantalum capacitors. Analyzed conditions include effects of vacuum and radiation, soldering (pop-corning), long-term storage, operation at high temperatures, stability at low and high temperatures, and anomalous transients.

Solar Orbiter will be used to examine how the Sun creates and controls the heliosphere, the vast bubble of charged particles blown by the solar wind into the interstellar medium. The spacecraft will combine in situ and remote sensing observations to gain new information about the solar wind, the heliospheric magnetic field, solar energetic particles, transient interplanetary disturbances and the Sun’s magnetic field.

The Orion mission, an ESA/NASA cooperative project, will be the next manned vehicle beyond Low Earth Orbit (LEO) and will enable manned missions to the Moon, Mars and asteroids. The new vehicle will be propelled by a service module based on the design and experience gained with the ATV, the ISS supply spacecraft with centralized procurement of the electronic components, in which Alter Technology participated for almost 10 years.
