Hi all, I am very pleased to announce poliastro 0.6.0, a MIT licensed, pure Python library for studying Orbital Mechanics and Astrodynamics problems! This is a new major release, focused on refactoring some internal core parts and improving the propagation functionality. Among the new features are: * Support for Python 3.6. * Allow propagation functions to receive a callback * New Orbit objects that supersede the State API. See the changelog for a more complete list of changes: http://poliastro.readthedocs.io/en/v0.6.0/changelog.html#new-in-poliastro-0-... You can install poliastro using either pip or conda: $ pip install poliastro $ conda install poliastro --channel conda-forge And cite it using this DOI: https://doi.org/10.5281/zenodo.290596 If you want to see an overview of poliastro capabilities, check out the gallery of Jupyter notebooks where we list some specific applications and interesting problems analyzed with this library: http://nbviewer.jupyter.org/github/poliastro/poliastro/blob/v0.6.0/index.ipy... And if you prefer video format, don't miss the recording of my talk on EuroPython 2016: https://youtu.be/VCpTgU1pb5k This release is probably the last one I'm going to make as an "almost aerospace engineer", so wish me luck for my MSc final project :) You can check its progress here: https://github.com/Juanlu001/pfc-uc3m poliastro is an open source collection of Python subroutines for solving problems in Astrodynamics and Orbital Mechanics. It combines cutting edge technologies like Python JIT compiling (using numba) with young, well developed astronomy packages (like astropy and jplephem) to provide a user friendly API for solving Astrodynamics problems. It is therefore an experiment to mix the best Python open source practices with my love for Orbital Mechanics. The project is still a work in progress and the API is subject to change. Contributions, bug reports, suggestions and advice are more than welcome!
