A New Model Inspired by the Pompeii Worm to Reverse Overheating in Nanosatellites
“Those who are inspired by a model other than Nature, a mistress above all masters, are labouring in vain.” attributed to Leonardo DaVinci Nanosatellites are exposed to extreme temperatures on the spacecraft surface, which can reach up to ±100 °C.

Fault-Tolerant Nanosatellite Computing on a Budget [PDF]
Micro- and nanosatellites have become popular platforms for a variety of commercial and scientific applications, but today are considered suitable mainly for short and low-priority space missions due to their low reliability. In part, this can be attributed to their reliance upon cheap, low-feature size, COTS components originally designed for embedded

ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Communication Subsystem for PilsenCUBE Nanosatellite [PDF]
This paper presents a design concept of new radio communication subsystem, intended for use on the PilsenCUBE nanosatellite. The hardware and software solution is based on previous experiences with the VZLUSAT-1 setup and operation. Our aim is to overcome weak points which were found, use modern powerful components actually available and build reliable

ABSTRACT Spectral interference induced by the water and the spatial resolution of many satellite images (≥ 10 m) limit the efficiency of remote sensing for monitoring riverine aquatic plant stands. In this study, the potential of using PlanetScope satellite images (3 m in spatial resolution, ~daily acquisition) for monitoring seasonal and interannual ...

Optimal Control of CubeSat Formations With Discrete On/Off Thrusters
The formation control of CubeSat‐class nanosatellites in low Earth orbit faces significant hurdles due to the discrete on/off nature and restricted switching frequency of their impulsive thrusters. A leader‐follower framework addresses these challenges by reformulating the control task as a constrained convex optimization problem that explicitly ...

Abstract The rapid development of low‐Earth orbit (LEO) satellites brings increased attention to spacecraft collisions, space debris, orbital decay, and satellite reentry. Neutral density and associated drag force on the satellite orbits elevate space risks, significantly determined by space weather disturbances, particularly geomagnetic storms.
