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.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.

Citizenship-by-investment programmes
United Kingdom
The UK offers three programmes for residency. The UK Overseas Business Representative Visa lets you open an overseas branch office of your existing company in the country at no extra investment. For the UK Tier 1 Innovator Visa, you are required to invest £50,000 (Dh238,000) into a business. You can also get a UK Tier 1 Investor Visa if you invest £2 million, £5m or £10m (the higher the investment, the sooner you obtain your permanent residency).
All UK residency visas get approved in 90 to 120 days and are valid for 3 years. After 3 years, the applicant can apply for extension of another 2 years. Once they have lived in the UK for a minimum of 6 months every year, they are eligible to apply for permanent residency (called Indefinite Leave to Remain). After one year of ILR, the applicant can apply for UK passport.
The Caribbean
Depending on the country, the investment amount starts from $100,000 (Dh367,250) and can go up to $400,000 in real estate. From the date of purchase, it will take between four to five months to receive a passport.
Portugal
The investment amount ranges from €350,000 to €500,000 (Dh1.5m to Dh2.16m) in real estate. From the date of purchase, it will take a maximum of six months to receive a Golden Visa. Applicants can apply for permanent residency after five years and Portuguese citizenship after six years.
“Among European countries with residency programmes, Portugal has been the most popular because it offers the most cost-effective programme to eventually acquire citizenship of the European Union without ever residing in Portugal,” states Veronica Cotdemiey of Citizenship Invest.
Greece
The real estate investment threshold to acquire residency for Greece is €250,000, making it the cheapest real estate residency visa scheme in Europe. You can apply for residency in four months and citizenship after seven years.
Spain
The real estate investment threshold to acquire residency for Spain is €500,000. You can apply for permanent residency after five years and citizenship after 10 years. It is not necessary to live in Spain to retain and renew the residency visa permit.
Cyprus
Cyprus offers the quickest route to citizenship of a European country in only six months. An investment of €2m in real estate is required, making it the highest priced programme in Europe.
Malta
The Malta citizenship by investment programme is lengthy and investors are required to contribute sums as donations to the Maltese government. The applicant must either contribute at least €650,000 to the National Development & Social Fund. Spouses and children are required to contribute €25,000; unmarried children between 18 and 25 and dependent parents must contribute €50,000 each.
The second step is to make an investment in property of at least €350,000 or enter a property rental contract for at least €16,000 per annum for five years. The third step is to invest at least €150,000 in bonds or shares approved by the Maltese government to be kept for at least five years.
Candidates must commit to a minimum physical presence in Malta before citizenship is granted. While you get residency in two months, you can apply for citizenship after a year.
Egypt
A one-year residency permit can be bought if you purchase property in Egypt worth $100,000. A three-year residency is available for those who invest $200,000 in property, and five years for those who purchase property worth $400,000.

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.
