NASA’s New Horizons Proves Deep-Space Navigation via Stellar Parallax

NASA’s New Horizons spacecraft carried out an unprecedented deep-space star navigation test while 438 million miles from Earth. Using its long-range camera in April 2020, it captured images of Proxima Centauri and Wolf 359, which appeared slightly shifted in the sky compared to Earth’s view – a striking demonstration of stellar parallax. It was the first-ever demonstration of deep-space stellar navigation. By comparing these images to Earth-based observations and a 3D star chart, scientists calculated New Horizons’ position to within about 4.1 million miles, only about 26 inches across the United States.

Stellar Parallax Test

According to the paper describing the results, accepted for publication in The Astronomical Journal, New Horizons’ camera imaged Proxima Centauri (4.2 light-years away) and Wolf 359 (7.86 light-years) on April 23, 2020. From the spacecraft’s distant vantage point, the two stars appear in different positions than seen from Earth – the essence of stellar parallax. By comparing those images with Earth-based data and a three-dimensional map of nearby stars, the team worked out the probe’s location to within about 4.1 million miles.

As lead author Tod Lauer explained, “Taking simultaneous Earth/Spacecraft images we hoped would make the concept of stellar parallaxes instantly and vividly clear”. He added, “It’s one thing to know something, but another to say ‘Hey, look! This really works!’”.

New Horizons and Future Missions

New Horizons, the fifth spacecraft to leave Earth and reach interstellar space, flew past Pluto and its moon Charon in 2015, sending home the first close-up images of those distant icy worlds. Now on an extended mission, the probe is studying the heliosphere.

New Horizons’ principal investigator Alan Stern called the parallax test “a pioneering interstellar navigation demonstration” that shows a spacecraft can use onboard cameras “to find its way among the stars”, in a statement. He also noted it “could be highly useful for future deep space missions in the far reaches of the Solar System and in interstellar space”

BTS member j-hope may be the face of Samsung’s newest Galaxy campaign, but fans hoping to see him at the company’s Unpacked event in London on Wednesday were left waiting.

j-hope did not appear in person during the presentation, where Samsung unveiled its latest generation of foldable devices. Instead, the rapper and dancer popped up on screen in a new advertisement introducing the Galaxy Z Fold 8 Wide, Samsung’s redesigned, wider foldable phone.

His absence from London was not entirely surprising. j-hope arrived in Seoul, South Korea, on Tuesday after BTS co-headlined the first-ever FIFA World Cup Final Halftime Show at New York-New Jersey MetLife Stadium on Sunday. The group performed their English-language hit “Dynamite” during the 11-minute production, which also featured Madonna, Shakira, Justin Bieber, Burna Boy, and several other performers.

But j-hope may have been promoting Samsung’s new device before the company officially announced it.

Photos and videos of the BTS member arriving at Incheon International Airport circulated among fans online, with eagle-eyed ARMY members noticing the unusually wide — and lavender! — foldable phone he was holding. It was the same phone he was spotted holding last week during soundcheck footage at a BTS World Tour stop in Paris. The device appeared to be the then-unreleased Galaxy Z Fold 8, prompting speculation that j-hope had given fans an early look at Samsung’s new design and color.

Samsung confirmed the phone during its July 22 Unpacked event in London. The company introduced the Galaxy Z Fold 8 with a shorter, wider design intended to make the foldable easier to hold and use. Samsung also unveiled the more traditionally shaped Galaxy Z Fold 8 Ultra and the Galaxy Z Flip 8.

Although some fans had hoped j-hope’s starring role in Samsung’s Unpacked promotional campaign meant he would attend the London launch, his involvement ultimately came through the advertisement that debuted during the event.

In hindsight, however, his airport appearance may have been the more fitting introduction. While Samsung waited until Unpacked to officially reveal the Galaxy Z Fold 8, j-hope had seemingly already unfolded it for the fans paying close attention.
