New Horizons Halfway from Pluto to Next Flyby Target

How time and a booster fly – generally when you’re creation story during 32,000 miles (51,500 kilometers) per hour.

Continuing on a trail by a outdoor regions of a solar system, NASA’s New Horizons booster has now trafficked half a stretch from Pluto – a storied initial aim – to 2014 MU69, a Kuiper Belt intent (KBO) it will fly past on Jan. 1, 2019. The booster reached that miracle during midnight (UTC) on Apr 3 – or 8 p.m. ET on Apr 2 – when it was 486.19 million miles (782.45 million kilometers) over Pluto and a same stretch from MU69.

A KBO among a Stars: In credentials for a New Horizons flyby of 2014 MU69 on Jan. 1, 2019, a spacecraft’s Long Range Reconnaissance Imager (LORRI) took a array of 10-second exposures of a credentials star margin nearby a plcae of a aim Kuiper Belt intent (KBO). This combination picture is done from 45 of these 10-second exposures taken on Jan. 28, 2017. The yellow solid outlines a likely plcae of MU69 on approach, though a KBO itself was too apart from a booster (544 million miles, or 877 million kilometers) even for LORRI’s telescopic “eye” to detect. New Horizons expects to start saying MU69 with LORRI in Sep of 2018 – and a group will use these newly acquired images of a credentials margin to assistance ready for that hunt on approach.

“It’s illusory to have finished half a tour to a successive flyby; that flyby will set a record for a many apart universe ever explored in a story of civilization,” pronounced Alan Stern, New Horizons principal questioner from a Southwest Research Institute in Boulder, Colorado.

Later this week – during 21:24 UTC (or 5:24 p.m. ET) on Apr 7 – New Horizons will also strech a median indicate in time between closest approaches to Pluto, that occurred during 7:48 a.m. ET on Jul 14, 2015, and MU69, likely for 2 a.m. ET on New Year’s Day 2019. The scarcely five-day disproportion between a median markers of stretch and time is due to a gravitational yank of a sun. The booster is indeed removing somewhat slower as it pulls divided from a sun’s gravity, so a booster crosses a median in stretch a bit before it passes a median in time.

Ready for a Rest

New Horizons will start a new duration of hibernation after this week. In fact, a booster will be sleeping by a Apr 7 median timing pen to MU69, given goal operators during a Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, will have put a booster into hibernation dual hours beforehand.

The scheduled 157-day hibernation is well-deserved; New Horizons has been “awake” for roughly dual and a half years, given Dec. 6, 2014. Since then, in further to a ancestral Pluto confront and 16 successive months of relaying a information from that confront behind to Earth, New Horizons has done breakthrough, distant observations of a dozen Kuiper Belt objects (KBOs), collected singular information on a dirt and charged-particle sourroundings of a Kuiper Belt, and complicated a hydrogen gas that permeates a immeasurable space surrounding a sun, called a heliosphere.

“The Jan 2019 MU69 flyby is a successive large eventuality for us, though New Horizons is truly a goal to some-more broadly try a Kuiper Belt,” pronounced Hal Weaver, New Horizons devise scientist from APL, in Laurel, Maryland. “In further to MU69, we devise to investigate some-more than two-dozen other KBOs in a stretch and magnitude a charged molecule and dirt sourroundings all a approach opposite a Kuiper Belt.”

New Horizons is now 3.5 billion miles (5.7 billion kilometers) from Earth; during that distance, a radio vigilance sent from a operations group – and roving during light speed – needs about 5 hours and 20 mins to strech a spacecraft. All booster systems are healthy and handling normally, and a booster is on march for a MU69 flyby.
