According to the analysis, 'Oumuamua's motion through our solar system is puzzling, appearing to accelerate along its trajectory — a typical feature of comets — but showing no evidence of the gaseous emissions that typically create this acceleration.

To accurately fly by and point the spacecraft's instruments at a smorgasbord of targets, engineers used trajectory correction maneuver, or TCM, thrusters that are identical in size and functionality to the attitude control thrusters, and are located on the back side of the spacecraft.

A handful of telescopes deployed by the New Horizons team in a remote part of Patagonia, Argentina were in the right place at the right time to catch its fleeting shadow — an event known as an occultation – and were able to capture important data to help mission flyby planners better determine the spacecraft trajectory and understand the size, shape, orbit and environment around MU69.

If greenhouse gas concentrations remain on their current trajectory, melting ice from Greenland alone could contribute as much as 24 feet to global sea level rise by the year 3000, which would place much of San Francisco, Los Angeles, New Orleans and other coastal cities underwater.
