LASP scientists spent the first hours of 2019 in a Maryland operations center watching NASA’s New Horizons spacecraft shoot past a minor planet more than 4 billion miles from Earth—the farthest object that any spacecraft has ever explored.
That icy object, an elongated body about 19 miles tall, is called 2014 MU69 or Ultima Thule, a Latin phrase that means “beyond the known world.”
CU Boulder researchers and students are playing an important role in this brush with the unknown, which took place on Jan. 1. As New Horizons zips through the outermost regions of our solar system, it will collect and analyze specks of dust using an instrument designed by students at LASP.
A LASP-led and University of Colorado Boulder student-built instrument riding on NASA’s New Horizons spacecraft found only a handful of dust grains, the building blocks of planets, when it whipped by Pluto at 31,000 miles per hour last July.
Data downloaded and analyzed by the New Horizons team indicated the space environment around Pluto and its moons contained only about six dust particles per cubic mile, said LASP planetary scientist and CU-Boulder Professor Fran Bagenal, who leads the New Horizons Particles and Plasma Team.
“The bottom line is that space is mostly empty,” said Bagenal. “Any debris created when Pluto’s moons were captured or created during impacts has long since been removed by planetary processes.”
After a nine-year journey of 3 billion miles, a piano-sized, power-packed NASA spacecraft has an upcoming date with history that some University of Colorado Boulder students, faculty and alumni wouldn’t miss for the world.
When NASA’s napping New Horizon’s spacecraft awakens later this week in preparation for its July 2015 encounter with Pluto, a University of Colorado Boulder student instrument onboard already will have been up for years.
The instrument, the Student Dust Counter (SDC), was designed and built to detect dust both on the interplanetary journey to Pluto and beyond, said CU-Boulder physics Professor and LASP research scientist Mihaly Horanyi, principal investigator on the effort. The SDC has been on for most of the mission—even as the other instruments primarily napped—measuring dust grains that are the building blocks of the solar system’s planets, he said.
LASP graduate student Andrew Poppe was recognized for his outstanding contributions to the Student Dust Counter instrument on board the New Horizons mission to Pluto.
The Venetia Burney Student Dust Counter (SDC), a CU/LASP-built instrument aboard the NASA New Horizons mission to Pluto, just became the record-holder for the most distant functioning space dust detector ever in space. On October 10, the SDC surpassed the previous record when it flew beyond 18 astronomical units—one unit is the distance between the… Read more »
