Nasa has “inadvertently” lost contact with Voyager 2, its pioneering spacecraft. The space agency said that it had sent a series of planned commands to the probe on 21 July. But those moves left Voyager 2 pointing in the wrong direction: its antenna is now pointing two degrees away from Earth, and so it has lost contact with its engineers. It cannot either receive commands or send back data, Nasa said. Ordinarily, it would do so by establishing contact with the Deep Space Network, or DSN, which is a set of ground-based antennas that allow for communications with distant spacecraft. But the data being sent by Voyager 2 is not reaching that network. Voyager 2 is now floating on its own, almost 20 billion kilometres from Earth. Nasa still hopes to be able to re-establish contact with the probe, however. It is programmed to automatically reset its orientation a number of times each year, to push its antenna back to Earth. The next reset is expected to happen on 15 October, Nasa said. Until then, the space agency expects the probe to “remain on its planned trajectory during the quiet period”, it said. As its name suggests, Voyager 2 was part of a pair, both of which were launched in 1977. Voyager 1 is floating even further from Earth – at 24 billion kilometres – and Nasa says it is continuing to operate as normal. The Voyager programme brought with it a host of records: Voyager 2 is the only spacecraft to have visited Uranus and Neptune, and together they are the only spacecraft made by humans to ever have entered interstellar space. Even almost 50 years since they were launched, the pair of Voyager spacecraft have continued to send back useful and important information to Nasa for examination by scientists on Earth. They have contributed to a host of new findings about the very distant edges of our solar system.

SEOUL, South Korea--(BUSINESS WIRE)--Oct 26, 2023--

New technology allows doctors to listen to the gurgle of people’s digestion and other noises to monitor their health. Doctors use sound inside their patients’ bodies to gather a host of information, listening to the air as it moves through their lungs or the beats of their heart, as well as the processing of food. They can provide important ways to understand people’s health – and noticing when they change or stop could be life-saving. But there is no easy way for doctors to monitor those things continually, or from a distance. Now a new breakthrough wearable allows doctors to continuously track those sounds by sticking technology to people’s skin. The soft, small wearables can be attached on almost any part of the body, in multiple locations, and will track the sounds without wires. Researchers have already used the device on 15 premature babies, as well as 55 adults, monitoring people with a variety of different conditions such as respiratory diseases. They found that the devices performed with clinical-grade accuracy – but also that they provided entirely new ways of caring for people. “Currently, there are no existing methods for continuously monitoring and spatially mapping body sounds at home or in hospital settings,” said Northwestern’s John A Rogers, a bioelectronics pioneer who led the device development. “Physicians have to put a conventional, or a digital, stethoscope on different parts of the chest and back to listen to the lungs in a point-by-point fashion. In close collaborations with our clinical teams, we set out to develop a new strategy for monitoring patients in real-time on a continuous basis and without encumbrances associated with rigid, wired, bulky technology.” One of the important breakthroughs in the device is that it can be used at various places at once – with researchers likening it to having a collection of doctors all listening at once. “The idea behind these devices is to provide highly accurate, continuous evaluation of patient health and then make clinical decisions in the clinics or when patients are admitted to the hospital or attached to ventilators,”said Dr Ankit Bharat, a thoracic surgeon at Northwestern Medicine, who led the clinical research in the adult subjects, in a statement. “A key advantage of this device is to be able to simultaneously listen and compare different regions of the lungs. Simply put, it’s like up to 13 highly trained doctors listening to different regions of the lungs simultaneously with their stethoscopes, and their minds are synced to create a continuous and a dynamic assessment of the lung health that is translated into a movie on a real-life computer screen.” The work is described in a new paper, ‘Wireless broadband acousto-mechanical sensing system for continuous physiological monitoring’, published in Nature Medicine.
