# Voyager 1 to Reach One Light‑Day from Earth, Alan Cummings Calls It Technological Milestone

*On 18 November 2026 the probe will be about 26 billion kilometres away, and its radio signal will require a full day to travel back to Earth.*

**Scores for the source reporting** (0-100, assessing the original journalism this article was written from, not this write-up): 

- Trust 86 of 100, higher is better. Trust high (86) due to NASA data, named astrophysicist, specific time, speed, and multiple independent outlets.
- Craft 95 of 100, higher is better. Critic score 95; article explains significance, quotes expert, provides precise figures, and outlines next milestone.
- Hype 12 of 100, lower is better. Hype low (12); language is factual with no sensationalist or click‑bait phrasing.

**The short version**

- Voyager 1 will be about 26 billion kilometres from Earth on 18 November 2026, one light‑day away.
- The probe’s radio signal will need roughly 24 hours to travel that distance.
- Alan Cummings of Caltech described the achievement as a technological milestone.
- Different outlets reported the event with varying levels of detail.

Voyager 1 was launched from Florida on 5 September 1977. On 18 November 2026 at 10:16 GMT the spacecraft will be approximately 26 billion kilometres from Earth, a distance that light covers in one day. At that separation the radio signal sent by the probe will require about 24 hours to reach the planet. The probe continues to travel at roughly 61 000 kilometres per hour through interstellar space.

Alan Cummings, senior researcher at Caltech’s Space Radiation Laboratory and a Voyager programme participant since 1973, said the one‑light‑day distance marks a technological milestone because communication remains possible at that range.

## Discrepancies

Rzeczpospolita’s digest states that the signal will take "exactly 24 hours," while Newsit.gr describes the travel time as "roughly 24 hours." The digest from Rzeczpospolita also says the distance is "more than 26 billion kilometres," whereas Newsit.gr gives the figure as "about 26 billion kilometres." Both characterisations appear in their respective reports.

## Newsit.gr

The full article from Newsit.gr notes the launch date, the Florida launch site, the spacecraft’s speed of about 61 000 km/h, and the precise time of 10:16 GMT on 18 November 2026 when Voyager 1 will be one light‑day away. It quotes Alan Cummings, who told Reuters that the achievement is a "technological milestone" and highlights that the probe still communicates with scientists. The piece does not mention Voyager 2, nor does it give an exact "24‑hour" figure for the signal travel time.

> I consider it a technological milestone, marking the astonishing longevity of Voyager 1 and our ability to communicate with it at this distance.
>
> — Alan Cummings, senior researcher, Caltech

## Rzeczpospolita

Rzeczpospolita’s digest reports that Voyager 1, launched 49 years ago, will become the first human‑made object to pass within one light‑day of Earth, a distance of more than 26 billion kilometres. It states that the radio signal will take exactly 24 hours to reach Earth. The summary does not include the launch location, the spacecraft’s speed, the quoted remark from Alan Cummings, or any reference to Voyager 2.

## infomoney.com.br

The infomoney.com.br digest mentions that Voyager 1 and its twin Voyager 2 were launched 49 years ago and explored the outer planets before continuing outward. It does not refer to the upcoming one‑light‑day milestone, the distance of 26 billion kilometres, the 24‑hour signal travel time, nor any statements from scientists.

## What the coverage left out

None of the digests mention the spacecraft’s speed of roughly 61 000 kilometres per hour. The infomoney.com.br digest omits any reference to the one‑light‑day distance and the 24‑hour signal travel time. Newsit.gr’s report does not discuss Voyager 2, and Rzeczpospolita’s digest does not include the quoted remark from Alan Cummings.

**26 billion km** — Distance at milestone (Equivalent to one light‑day)

## How the sides framed it

### Left

- The left-rated outlets Al Jazeera, Associated Press News and The Washington Post all reported that Voyager 1 is set to become the first human-made object to travel one light-day from Earth. They noted this distance is over 16 billion miles.
- Al Jazeera stated the probe launched in 1977 and travels at about 36,000 miles per hour. This report also mentioned Voyager 1 took the "Pale Blue Dot" photo and that communication was briefly lost in October.
- Bill Nye of the Planetary Society was quoted by Al Jazeera. The Associated Press News and The Washington Post digests did not include quotes or further details beyond the main announcement.

### Centre

- All five centre‑rated outlets reported that NASA’s Voyager 1 is about to become the first human‑made object to reach one light‑day from Earth. Each noted the distance exceeds 16 billion miles and that the milestone is expected on Wednesday. All also mentioned that Voyager 2 is not due to reach the same point until 2035.
- Washington Top News provided a full report that added quotations from project manager Suzanne Dodd, who called Voyager 1 a national treasure and urged the public to flash Morse code after sunset. The article gave the spacecraft’s speed of 38,000 mph, described a recent power‑conserving manoeuvre, a brief loss of contact, weekly command cycles, and cited remarks from Carl Sagan, Bill Nye and details of the Golden Record.
- The digests reproduced by City News, KOB 4, Newsday and Wral News contained only the basic milestone description and did not include any quotations, the public outreach suggestion, speed data, power‑conserving effort, recent contact issue, or historical context such as the Pale Blue Dot image or the Golden Record. Those details appear solely in Washington Top News’ full report.

### Right

## Questions

**When will Voyager 1 be one light‑day from Earth?**

Voyager 1 will reach a distance of about 26 billion kilometres, or one light‑day, on 18 November 2026 at 10:16 GMT, according to the reports.

**How long will the probe’s radio signal take to travel back to Earth?**

At the one‑light‑day distance the radio signal will need roughly 24 hours to reach Earth; one digest says it will take exactly 24 hours, while another describes it as roughly 24 hours.

**What did Alan Cummings say about the milestone?**

Alan Cummings, a senior researcher at Caltech, called reaching one light‑day a technological milestone and highlighted that communication with Voyager 1 remains possible at that range.

**Did any outlet mention Voyager 2?**

Only the infomoney.com.br digest referenced Voyager 2, noting that both probes were launched 49 years ago and explored the outer planets before moving onward.
