New Horizons Space Probe Gets Mission Extension

Hills of water ice on Pluto ‘float’ in a sea of frozen nitrogen and move over time like icebergs in Earth’s Arctic Ocean—another example of Pluto’s fascinating geological activity. The New Horizons spacecraft passed Pluto in July of 2015.

The U.S. space agency has announced it is extending the mission of the New Horizons spacecraft.

 

New Horizons is a spacecraft without a human crew. It was the first spacecraft to visit the dwarf planet Pluto. It gathered pictures and information about the dwarf planet. New Horizons flew close to Pluto in July of 2015.

 

The spacecraft will be heading further into what is known as the Kuiper Belt. The Kuiper Belt is an area beyond the planets where there are asteroids and comets.

 

New Horizons will visit an “ancient object” called 2014 MU69.

 

The spacecraft is expected to reach the object on January 1, 2019. NASA says the 2014 MU69 is more than one and a half billion kilometers beyond the orbit of Pluto.

 

NASA calls 2014 MU69 “one of the early building blocks of the solar system”.

 

Jim Green is NASA’s director of Planetary Science. He said, “The New Horizons mission to Pluto exceeded our expectations.” He added that NASA is looking forward to continuing explorations with the spacecraft.

 

“We’re excited to continue onward into the dark depths of the outer solar system,” he said.

 

Green said scientists did not know about 2014 MU69 when New Horizons was launched. New Horizons left Earth in January of 2006.


 

NASA also said it was keeping the Dawn spacecraft in orbit around the dwarf planet Ceres. Ceres is much closer to Earth. It orbits the Sun between the planets Mars and Jupiter.

 

Green said Dawn will continue to observe Ceres in an effort to make more discoveries.

 

Dawn was launched in September of 2007.
