At mission control, CU contingent shares moment of triumph

When NASA鈥檚 New Horizons spacecraft left Earth for Pluto in 2006,聽Jamey Szalay聽(PhDPhys鈥15) was in high school.

At 7:50 a.m. EST on July 14, 2015, as the spacecraft traveled within a cosmic breath of Pluto鈥檚 surface, he was a physicist with a stake in the mission.

鈥淭hat was a pretty big moment for us,鈥 says Szalay, a CU-麻豆影院 doctoral candidate who has led data analysis for the Student Dust Counter, one of CU鈥檚 many contributions to the historic space voyage. The student-built device helps analyze space鈥檚 composition.

Scores of CU students, faculty, alumni and staff have participated in the decade-long mission, in which a spacecraft reached Pluto for the first time, then kept going.

Szalay, 27, was part of a CU contingent camped at mission control in Maryland in the days leading up to a series of climactic moments. Compatriots included fellow dust counter experts Marcus Piquette, also a student, and faculty physicist Mihaly Horanyi, who oversaw the project.

Celebrations began when the spacecraft was believed to be closest to Pluto鈥檚 surface, about 7,800 miles distant. They reignited with definitive word from New Horizons 14 hours later.

鈥淭hat was the moment of relief,鈥 says Szalay. 鈥淚t was a big hold-your-breath until the spacecraft talks to you.鈥

Front and center throughout the triumph was聽Alan Stern聽(PhDAstro鈥89), chief mission scientist and the subject of the summer聽Coloradan鈥檚 cover story, 鈥Voyage to Pluto.

Like Szalay, Stern was having the time of his life.

鈥淚 don鈥檛 think any one of us could have imagined that this could have been a better toy store,鈥 he said July 15, referring to the initial scientific bounty.

Indeed, New Horizons has already offered tantalizing new details about Pluto: It鈥檚 geologically active and has grand mountain ranges, plus a vast region shaped like a giant Valentine鈥檚 Day heart.

There鈥檚 still plenty for scientists to do: It will take about 16 months for the spacecraft to send all its new observations to Earth. Analyzing the data will take years 鈥 music to Szalay鈥檚 ears.

鈥淣othing trumps space science,鈥 he says.
