Orbit control of high area-to-mass ratio spacecraft using electrochromic coating
, 2010 This paper presents a novel method for the orbit control of high area-to-mass ratio spacecraft, such as spacecraft-on-a-chip, future „smart dust‟ devices and inflatable spacecraft.

People and Nature, EarlyView.Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

Digital surveillance of animals and nature recovery
People and Nature, EarlyView.Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Solar radiation pressure augmented deorbiting from high altitude sun-synchronous orbits
, 2012 This paper discusses the use of solar radiation pressure (SRP) augmented deorbiting to passively remove small satellites from high altitude Sun-synchronous orbits. SRP-augmented deorbiting works by deploying a light-weight reflective inflatable device to

Drag-free Satellite SimulatorWe have been investigating a possibility of launching a satellite in a planetary orbit to test the general theory of relativity. As a first step of it, we have fabricated a drag-free system model for a laboratory simulation in order to acquire the fundamental technique and find unexpected problems.

Shingle Interconnection Reliability of PERC and Thin HJT Cells for Low Earth Orbit Applications
Progress in Photovoltaics: Research and Applications, EarlyView.Evolution of maximum power output (Pmax$$ {}_m ax $$) of PERC and thin HJT shingled cells with the Electrically Conductive Adhesives (ECA) “S” and “A” exposed to +120°C/−$$ - $$120°C thermal cycles up to 5×103$$ 5\times 1{0}^3 $$ times. Losses are induced by an increased series resistance with all cell technologies and ECA. Imaging (electroluminescence
