Specify maximum frequency of optima per destination across launch year window. Parameter to minimize if more than one trajectory per destination is found to meet above constraints. Maximum total ΔV (indicator of propellant requirement) from a 200 km circular Low-Earth Orbit (LEO). Maximum acceptable total mission duration. Range of acceptable launch years, assumed to refer to January 1 st of bounding years. Specify if the trajectory is to include an Earth-return segment and indicate nature of encounter. 'Apophis', 'Mars', or '2010 UE51'.Ī list of NEOs matching specific parameters of interest can be generated with the Where 0 indicates a well-determined orbit and 9 insufficient observations for long-term orbit prediction.Īlternatively include a custom list of NEOs or planets, one object per line. Update library when browsers binaries are installed separetly to non standard location.

The orbit condition code is an integer between 0 and 9 indicating how well an object's orbit is known, Install Browser library from PyPi with pip: > pip install -upgrade robotframework-browser.
For example, a magnitude 25 object is approximately 35 m in size whereas a magnitude 20 object is about 350 m in diameter. Near-Earth Objects (NEOs) are bodies that orbit the sun with perihelion distance less than 1.3 AU.Ī body's absolute magnitude gives a rough idea of its size. This page features a tool to find spacecraft trajectories to planets and small-bodies.įor ideas of what to search for, view the example queries page.Ī user guide is also available explaining search constraints, the methodology behind trajectory computations and the important limitations of the tool.
