passed Pluto in 2015.

With public input, the mission team has nicknamed the spacecraft’s next target – on the fringes of our solar system – Ultima Thule.

Some 115,000 people from around the world recently suggested some 34,000 possible nicknames for the distant object 2014 MU69, the next target of the New Horizons spacecraft, whose historic sweep past Pluto took place in July 2015. The New Horizons mission team announced on March 13, 2018, it has selected the name Ultima Thule – pronounced ultima thoo-lee – for New Horizon’s next target, a Kuiper Belt object officially named 2014 MU69. New Horizons will sweep closest to Ultima Thule on January 1, 2019. The mission team describes the object as:

“… the most primitive world ever observed by spacecraft, in the farthest planetary encounter in history….”

In a statement, the team explained their reasons for their choice:

“Thule was a mythical, far-northern island in medieval literature and cartography. Ultima Thule means “beyond Thule” – beyond the borders of the known world – symbolizing the exploration of the distant Kuiper Belt and Kuiper Belt objects that New Horizons is performing, something never before done.”

Alan Stern of Southwest Research Institute in Boulder, Colorado, is New Horizons’ principal investigator. He said:

“MU69 is humanity’s next Ultima Thule. Our spacecraft is heading beyond the limits of the known worlds, to what will be this mission’s next achievement. Since this will be the farthest exploration of any object in space in history, I like to call our flyby target Ultima, for short, symbolizing this ultimate exploration by NASA and our team.”

NASA and the New Horizons team launched the nickname campaign in early November. Hosted by the SETI Institute of Mountain View, California, and led by Mark Showalter, an institute fellow and member of the New Horizons science team, the online contest sought nominations from the public and stipulated that a nickname would be chosen from among the top vote-getters.

The campaign wrapped up on December 6, after a five-day extension to accommodate more voting. Of the 34,000 names suggested, 37 reached the ballot for voting and were evaluated for popularity. This included eight names suggested by the New Horizons team and 29 nominated by the public.

The team then narrowed its selection to the 29 publicly nominated names and gave preference to names near the top of the polls. Names suggested included Abeona, Pharos, Pangu, Rubicon, Olympus, Pinnacle and Tiramisu. Final tallies in the naming contest posted here.

About 40 members of the public nominated the name Ultima Thule. This name was one of the highest vote-getters among all name nominees. Showalter said:

“We are grateful to those who proposed such an interesting and inspirational nickname. They deserve credit for capturing the true spirit of exploration that New Horizons embodies.”

After the flyby, NASA and the New Horizons team say they’ll choose a formal name to submit to the International Astronomical Union, based in part on whether MU69 is found to be a single body, a binary pair, or perhaps a system of multiple objects.

Bottom line: With public input, the New Horizons mission team has given the nickname Ultima Thule to the spacecraft’s next target, Kuiper Belt Object 2014 MU69.

Founded on March 10, 1942—just three months after the United States entered World War II—APL was created as part of a federal government effort to mobilize scientific resources to address wartime challenges.

APL was assigned the task of finding a more effective way for ships to defend themselves against enemy air attacks. The Laboratory designed, built, and tested a radar proximity fuze (known as the VT fuze) that significantly increased the effectiveness of anti-aircraft shells in the Pacific—and, later, ground artillery during the invasion of Europe. The product of the Laboratory’s intense development effort was later judged to be, along with the atomic bomb and radar, one of the three most valuable technology developments of the war.

On the basis of that successful collaboration, the government, The Johns Hopkins University, and APL made a commitment to continue their strategic relationship. The Laboratory rapidly became a major contributor to advances in guided missiles and submarine technologies. Today, more than seven decades later, the Laboratory’s numerous and diverse achievements continue to strengthen our nation.

APL continues to relentlessly pursue the mission it has followed since its first day: to make critical contributions to critical challenges for our nation.

Johns Hopkins Campus

The Johns Hopkins University opened in 1876, with the inauguration of its first president, Daniel Coit Gilman. “What are we aiming at?” Gilman asked in his installation address. “The encouragement of research … and the advancement of individual scholars, who by their excellence will advance the sciences they pursue, and the society where they dwell.”

The mission laid out by Gilman remains the university’s mission today, summed up in a simple but powerful restatement of Gilman’s own words: “Knowledge for the world.”

What Gilman created was a research university, dedicated to advancing both students’ knowledge and the state of human knowledge through research and scholarship. Gilman believed that teaching and research are interdependent, that success in one depends on success in the other. A modern university, he believed, must do both well. The realization of Gilman’s philosophy at Johns Hopkins, and at other institutions that later attracted Johns Hopkins-trained scholars, revolutionized higher education in America, leading to the research university system as it exists today.
