-  This Review is visiting the sub planets in the Kuiper Belt of asteroids.  The next rendezvous is to be the KBO MU69 asteroid on January 2019.  This region of our solar system supports a large population of terrestrial and dwarf planets. 
-
-  MU60 was our first discovered in 2014 using the Hubble Telescope.  MU69 has a circular orbit taking 296 years at 44.4 astronomical units from the Sun.  One Astronomical Unit is the Earth -Sun distance of 93 million miles.    
-
-  MU69 orbit inclines just 2.5 degrees from the plane of the solar system.  Its diameter is estimated to be 12 to 25 miles.
-
-  Horizon hopes to pass MU69 within 2,175 miles.  The flyby will occur at 33,000 miles per hour.  MU69 may have moons of its own.  If so the wobble caused by the orbiting gravity pull of the satellites will allow astronomers to calculate the mass and density of MU69.  
-
-  The communications with Horizon has a 12 hour round trip delay.  The travel time of light and radio signals.  This will present a challenge for course corrections coming from the Space Center.
-
-  The first images should begin arriving this month, August, 2018.  The Space Center is planning up to six possible course corrections with engine firings to target the wanted intercept.
-
-  The flyby in January 2019 will be so quick for an object this small allowing only a few days to record the entire visit.  All seven instruments on board will record all the science collected.
-
-   If successful the flyby could record resolutions as good as 100 feet per pixel.  It should be able to detect satellite moons down to 1/2 mile in diameter.  The smallest moon detected around Pluto was 10 by 5 by 6 miles across.
-
-  Horizon only has a 30 watt transmitter and it is 4,000,000,000 miles away.   It will take 22 months to download all the data that is collected.  That will take us to the fall of 2020.
-
-  Horizon will continue its mission and will study more than 24 Kuiper Belt other objects on its journey out of the solar system.  After that Horizon will be studying The Sun's distant heliosphere using an ultraviolet spectrometer. plasma, and dust detectors. 
-
-  The engineering was so good on Horizon that it should be operational for 20 more years well into the boundary of interstellar space.  Beyond Kuiper Belt objects Horizon is prepared to study extragalactic background light, microlensing, and variable stars.
-
-  The Kuiper Belt contains thousands of objects that w cannot study from Earth.  They are too small and too far away.  This is our big chance to learn as much as we can.  It is like pebbles of knowledge on the beach with  whole ocean of the unknown in front of us.
