A Nasa spacecraft exploring interstellar space is sending back strange data that has left engineers puzzled.
Voyager 1, launched 45 years ago, is transmitting data from interstellar space that does not match what is actually happening on board, Nasa said on Wednesday.
The craft and its twin Voyager 2 have operated far longer than anyone expected and are the only spacecraft to collect data in interstellar space — a region that is not influenced by the Sun.
“A mystery like this is sort of par for the course at this stage of the Voyager mission,” said Suzanne Dodd, project manager for Voyager 1 and 2 at Nasa’s Jet Propulsion Laboratory in southern California.
“The spacecraft are both almost 45 years old, which is far beyond what the mission planners anticipated.
“We’re also in interstellar space — a high-radiation environment that no spacecraft have flown in before. So, there are some big challenges for the engineering team. But I think if there’s a way to solve this issue with the AACS (attitude articulation and control system), our team will find it.”
The spacecraft is operating normally, receiving and executing commands from Earth and is gathering and returning data.
However, data from the AACS, which controls the spacecraft’s orientation, does not reflect what is happening on board Voyager 1.
The AACS also keeps the spacecraft’s high-gain antenna pointed precisely at Earth, enabling it to send data home.
Nasa said that all signs suggest that the system is still working, but the telemetry data it is returning is invalid.
Voyager 1 is 23.3 billion kilometres from Earth, which means it takes about two days to send a message to Voyager 1 and get a response.
Voyager 2 is 19.5 billion km from Earth and is also operating normally.
Both spacecraft are helping shed light on the region outside of the solar system environment, and have helped search for the heliopause boundary — the point in space where interstellar space starts.

Four reasons global stock markets are falling right now
There are many factors worrying investors right now and triggering a rush out of stock markets. Here are four of the biggest:
1. Rising US interest rates
The US Federal Reserve has increased interest rates three times this year in a bid to prevent its buoyant economy from overheating. They now stand at between 2 and 2.25 per cent and markets are pencilling in three more rises next year.
Kim Catechis, manager of the Legg Mason Martin Currie Global Emerging Markets Fund, says US inflation is rising and the Fed will continue to raise rates in 2019. “With inflationary pressures growing, an increasing number of corporates are guiding profitability expectations downwards for 2018 and 2019, citing the negative impact of rising costs.”
At the same time as rates are rising, central bankers in the US and Europe have been ending quantitative easing, bringing the era of cheap money to an end.
2. Stronger dollar
High US rates have driven up the value of the dollar and bond yields, and this is putting pressure on emerging market countries that took advantage of low interest rates to run up trillions in dollar-denominated debt. They have also suffered capital outflows as international investors have switched to the US, driving markets lower. Omar Negyal, portfolio manager of the JP Morgan Global Emerging Markets Income Trust, says this looks like a buying opportunity. “Despite short-term volatility we remain positive about long-term prospects and profitability for emerging markets.”
3. Global trade war
Ritu Vohora, investment director at fund manager M&G, says markets fear that US President Donald Trump’s spat with China will escalate into a full-blown global trade war, with both sides suffering. “The US economy is robust enough to absorb higher input costs now, but this may not be the case as tariffs escalate. However, with a host of factors hitting investor sentiment, this is becoming a stock picker’s market.”
4. Eurozone uncertainty
Europe faces two challenges right now in the shape of Brexit and the new populist government in eurozone member Italy.
Chris Beauchamp, chief market analyst at IG, which has offices in Dubai, says the stand-off between between Rome and Brussels threatens to become much more serious. "As with Brexit, neither side appears willing to step back from the edge, threatening more trouble down the line.”
The European economy may also be slowing, Mr Beauchamp warns. “A four-year low in eurozone manufacturing confidence highlights the fact that producers see a bumpy road ahead, with US-EU trade talks remaining a major question-mark for exporters.”
