Within the weeks following its launch in early 2006, when NASA’s New Horizons was nonetheless near dwelling, it took simply minutes to transmit a command to the spacecraft, and listen to again that the onboard laptop obtained and was prepared to hold out the directions.


As New Horizons crossed the photo voltaic system, and its distance from Earth jumped from tens of millions to billions of miles, that point between contacts grew from a couple of minutes to a number of hours. And on April 17 at 12:42 UTC (or April 17 at 8:42 a.m. EDT), New Horizons will attain a uncommon deep-space milepost—50 astronomical items from the solar, or 50 instances farther from the solar than Earth is.

New Horizons is simply the fifth spacecraft to succeed in this nice distance, following the legendary Voyagers 1 and a pair of and their predecessors, Pioneers 10 and 11. It is virtually 5 billion miles (7.5 billion kilometers) away; a distant the place a kind of radioed instructions, even touring on the pace of sunshine, wants seven hours to succeed in the far off spacecraft. Then add seven extra hours earlier than its management group on Earth finds out if the message was obtained.

“It is arduous to think about one thing so far-off,” stated Bowman, the New Horizons mission operations supervisor on the Johns Hopkins Utilized Physics Laboratory in Laurel, Maryland. “One factor that makes this distance tangible is how lengthy it for us on Earth to substantiate that the spacecraft obtained our directions. This went from virtually instantaneous to now being on the order of 14 hours. It makes the intense distance actual.”

To mark the event, New Horizons lately photographed the star discipline the place one in every of its long-distance cousins, Voyager 1, seems from New Horizons’ distinctive perch within the Kuiper Belt. By no means earlier than has a spacecraft within the Kuiper Belt photographed the placement of an much more distant spacecraft, now in interstellar house. Though Voyager 1 is way too faint to be seen within the , its location is thought exactly as a consequence of NASA’s radio monitoring.

Hiya, Voyager! From the distant Kuiper Belt on the photo voltaic system’s frontier, on Christmas Day, Dec. 25, 2020, NASA’s New Horizons spacecraft pointed its Lengthy Vary Reconnaissance Imager within the path of the Voyager 1 spacecraft, whose location is marked with the yellow circle. Voyager 1, the farthest human-made object and first spacecraft to really depart the photo voltaic system, is than 152 astronomical items (AU) from the solar—about 14.1 billion miles or 22.9 billion kilometers—and was 11.2 billion miles (18 billion kilometers) from New Horizons when this picture was taken. Voyager 1 itself is about 1 trillion instances too faint to be seen on this picture. Many of the objects within the picture are stars, however a number of of them, with a fuzzy look, are distant galaxies. New Horizons reaches the 50 AU mark on April 18, 2021, and can be part of Voyagers 1 and a pair of in interstellar house within the 2040s.

“That is a hauntingly stunning picture to me,” stated Alan Stern, New Horizons principal investigator from the Southwest Analysis Institute in Boulder, Colorado.

“Wanting again on the flight of New Horizons from Earth to 50 AU virtually appears in a roundabout way like a dream,” he continued. “Flying a spacecraft throughout our whole photo voltaic system to discover Pluto and the Kuiper Belt had by no means been completed earlier than New Horizons. Most of us on the group have been part of this mission because it was simply an thought, and through that point our have grown up, and our mother and father, and we ourselves, have grown older. However most significantly, we made many scientific , impressed numerous STEM careers, and even made a bit historical past.”

New Horizons was virtually designed to make historical past. Dispatched at 36,400 miles per hour (58,500 kilometers per hour) on Jan. 19, 2006, New Horizons was and remains to be the quickest human-made object ever launched from Earth. Its gravity-assist flyby of Jupiter in February 2007 not solely shaved about three years from its voyage to Pluto, however allowed it to make one of the best views ever of Jupiter’s faint ring, and seize the primary film of a volcano erupting anyplace within the photo voltaic system besides Earth.

New Horizons efficiently pulled off the primary exploration of the Pluto system in July 2015, adopted by the farthest flyby in historical past—and first close-up have a look at a Kuiper Belt object (KBO)—with its flight previous Arrokoth on New Yr’s day 2019. From its distinctive perch within the Kuiper Belt, New Horizons is making observations that may’t be constituted of anyplace else; even the celebrities look completely different from the spacecraft’s perspective.

New Horizons group members use large telescopes just like the Japanese Subaru observatory to scan the skies for an additional potential (and long-shot) KBO flyby goal, New Horizons itself stays wholesome, accumulating information on the photo voltaic wind and house atmosphere within the Kuiper Belt, different Kuiper Belt objects, and distant planets like Uranus and Neptune. This summer time, the mission group will transmit a software program improve to spice up New Horizons’ scientific capabilities. For future exploration, the spacecraft’s nuclear battery ought to sufficient energy to maintain New Horizons working till the late 2030s.
