bullet::::1. the orbit of every planet is an ellipse with the sun at one of the two foci.









































bullet::::2. a line joining a planet and the sun sweeps out equal areas during equal intervals of time.









































bullet::::3. the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
two-body problem in general relativity
following launch, mxl was unable to command m-cubed, and observed anomalies in its transmitted data. mxl concluded that the m-cubed cubesat became magnetically conjoined to explorer-1 prime, a second cubesat released at the same time, via both satellites' attitude control magnets. this is the first recorded instance of two satellites unintentionally and non-destructively latching together. as a result of this incident, m-cubed was unable to complete its mission.









































the m-cubed mission was successfully re-flown as mcubed-2, launched on december 6, 2013.
