A deep space experiment has resulted in the receiving of a laser-beamed message from 16 million kilometres away, Nasa reported this week - an event that could revolutionise the future of deep space missions.
The laser transceiver that made the connection is on board the Psyche spacecraft, which is on a two-year mission headed for the asteroid belt between Mars and Jupiter, Science Alert reported.
Psyche will spend the next six years travelling about 3.6 billion kilometres to reach the outer part of the main asteroid belt, the location of a metal asteroid bearing its name.
Along for the ride is the Deep Space Optical Communications technology demonstration, or DSOC, which was designed to carry out Nasa's most distant experiment of high-bandwidth laser communications.
The spacecraft made contact with the Hale Telescope at the Palomar Observatory in California.
The mission achieved “first light” - the successful sending and receiving of its first batch of data - on November 14 when the laser transceiver locked on to Jet Propulsion Laboratory's powerful uplink laser beacon at its Table Mountain Observatory, IFL Science reported.
This allowed the DSOC’s transceiver to aim its downlink laser at Caltech’s observatory 130km away.
“Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars,” Trudy Kortes, director of Technology Demonstrations at Nasa, said in a statement.
Psyche is scheduled for a fly-by around Mars and so tests will continue to be carried out to refine and improve this innovative communication method.

Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

Conflict, drought, famine
Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.
Band Aid
Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.

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.
