AEROS: Oceanographic Hyperspectral Imaging and Argos-Tracking CubeSat
Sophie Prendergast, Cadence Payne, Miles Lifson +24
AEROS is a 3U CubeSat pathfinder toward a future ocean-observing constellation, targeting the Portuguese Atlantic region. AEROS features a miniaturized, high-resolution Hyperspectr…
MAGAL Constellation -- Using a Small Satellite Altimeter Constellation to Monitor Local and Regional Ocean and Inland Water Variations
André G. C. Guerra, André João, Miguel Arantes +18
MAGAL lays the foundations for a future constellation of small satellites carrying radar altimeters aiming to improve the understanding of ocean circulation variability at local, r…
The AEROS ocean observation mission and its CubeSat pathfinder
Rute Santos, Orfeu Bertolami, E. Castanho +21
AEROS aims to develop a nanosatellite as a precursor of a future system of systems, which will include assets and capabilities of both new and existing platforms operating in the O…
Development, manufacturing and testing of small launcher structures from Portugal
André G. C. Guerra, Daniel Alonso, Catarina Silva +11
During the last decades the industry has seen the number of Earth orbiting satellites rise, mostly due to the need to monitor Earth as well as to establish global communication net…
Magrathea: Dust growth experiment in micro-gravity conditions
André G. C. Guerra, Adrián Banos García, Adrián Castanón Esteban +14
One of the least understood processes in astrophysics is the formation of planetesimals from molecules and dust within protoplanetary disks. In fact, current methods have strong li…
Thermal analysis of the electronics of a CubeSat mission
André G. C. Guerra, Diego Nodar-López, Ricardo Tubó-Pardavila
CubeSat satellites are small cube-shaped space platforms that are very popular among academic, research and start-up communities mostly due to their reduced mission costs and short…
Integrating Small Satellite Communication in an Autonomous Vehicle Network: A Case for Oceanography
André G. C. Guerra, António Sérgio Ferreira, Maria Costa +2
Small satellites and autonomous vehicles have greatly evolved in the last few decades. Hundreds of small satellites have been launched with increasing functionalities, in the last…
Estimating the thermally induced acceleration of the New Horizons spacecraft
André G. C. Guerra, Frederico Francisco, Paulo J. S. Gil +1
Residual accelerations due to thermal effects are estimated through a model of the New Horizons spacecraft and a Monte Carlo simulation. We also discuss and estimate the thermal ef…
Orbital motions of astronomical bodies and their Centre of Mass from different reference frames: a conceptual step between the Geocentric and Heliocentric models
André G C Guerra, Paulo Simeão Carvalho
The motion of astronomical bodies and the centre of mass of the system is not always well perceived by students. One of the struggles is the conceptual change of reference frame, w…
On Small Satellites for Oceanography: A Survey
André G. C. Guerra, Frederico Francisco, Jaime Villate +3
The recent explosive growth of small satellite operations driven primarily from an academic or pedagogical need, has demonstrated the viability of commercial-off-the-shelf technolo…
Comparison of Four Space Propulsion Methods for Reducing Transfer Times of Crewed Mars Mission
A. G. C. Guerra, O. Bertolami, P. J. S. Gil
We assess the possibility of reducing the travel time of a crewed mission to Mars by examining four different propulsion methods and keeping the mass at departure under 2500 tonne,…
Studying the vertex structure using recent LHC results
César Bernardo, N. F. Castro, Miguel C. N. Fiolhais +4
The vertex structure and the search for new anomalous couplings is studied using top quark measurements obtained at the LHC, for a centre-of-mass energy of 8 TeV. By combinin…
