Radar satellite launched by India and NASA will track minuscule changes to Earth's land and ice
FLORIDA: NASA and India paired up to launch an Earth-mapping satellite on Wednesday capable of tracking even the slightest shifts in land and ice. The $1.3 billion mission will help forecasters and first responders stay one step ahead of floods, landslides, volcanic eruptions and other disasters, according to scientists. Rocketing to orbit from India, the satellite will survey virtually all of Earth's terrain multiple times. Its two radars — one from the US and the other from India — will operate day and night, peering through clouds, rain and foliage to collect troves of data in extraordinary detail. Microwave signals beamed down to Earth from the dual radars will bounce back up to the satellite's super-sized antenna reflector perched at the end of a boom like a beach umbrella. Scientists will compare the incoming and outgoing signals as the spacecraft passes over the same locations twice every 12 days, teasing out changes as small as a fraction of an inch (1 centimeter). It's 'a first-of-its-kind, jewel radar satellite that will change the way we study our home planet and better predict a natural disaster before it strikes,' NASA's science mission chief Nicky Fox said ahead of liftoff. Fox led a small NASA delegation to India for the launch. It will take a full week to extend the satellite's 30-foot (9-meter) boom and open the 39-foot-in-diameter (12-meter) drum-shaped reflector made of gold-plated wire mesh. Science operations should begin by the end of October. Among the satellite's most pressing measurements: melting glaciers and polar ice sheets; shifting groundwater supplies; motion and stress of land surfaces prompting landslides and earthquakes; and forest and wetland disruptions boosting carbon dioxide and methane emissions. NASA is contributing $1.2 billion to the three-year mission; it supplied the low-frequency radar and reflector. The Indian Space Research Organization's $91 million share includes the higher-frequency radar and main satellite structure, as well as the launch from a barrier island in the Bay of Bengal. It's the biggest space collaboration between the two countries. The satellite called NISAR — short for NASA-ISRO Synthetic Aperture Radar — will operate from a near-polar-circling orbit 464 miles (747 kilometers) high. It will join dozens of Earth observation missions already in operation by the US and India.

‘Unprecedented' algae bloom disaster making SA beaches toxic here to stay, experts claim
An 'unprecedented' natural disaster that has killed thousands of marine creatures, sparked orders to stay out of the water, and gutted parts of the local tourism sector has scientists alarmed, with no sign of an end in sight. The Algae bloom parked up just off the coast of South Australia has persistently held its position inside the St Vincent Gulf since it was first officially reported in March, after visitors of the Waitpinga Beach on South Australia's Fleurieu Peninsula began reporting illness. The toxic bloom has killed hundreds of sea creatures, caused illness in humans and sparked orders for swimmers to stay out of affected water. Estimates vary on how many creatures have been killed by the bloom, but it is understood there have been recorded deaths among more than 200 different species of sea life. Even more alarmingly, there doesn't seem to be any respite in sight. Dr Nina Wootton, a Marine Scientist from the School of Biological Sciences at the University of Adelaide, said tracking the outbreak of the Algae bloom was difficult, but it could have something to do with the Murray River flooding in 2022/23. 'Obviously there's a lot of run-off that goes into the Murray, and then this has potentially pushed some of these algae species out into the marine environment, and it's sort of just been sitting there dormant. And then when we see perfect conditions arise, it can then bloom,' she told NewsWire. 'Somehow this species has gotten there, and then we have a range of different environmental factors that have caused this perfect storm of events,' she said. 'When things are hot and still, (the algae) grow, and this species has just boomed because there's been nothing there to break it up naturally.' Although millions of dollars have been committed to clean up and research, Dr Wootton said the cure was ultimately in the hands of mother nature. 'The thing that's so hard is there's not really a solution to get rid of this bloom,' Dr Wootton said. 'The main way we're going to be able to do it is hopefully cross our fingers and toes that we have good weather conditions and we have some strong winter storms over the next couple of months that will break it up and eventually blow it off the coast. That's all we can really hope for now … to get rid of it naturally at least,' she said. 'It could be up to 18 months. Some scientists are predicting that we're going to continue to see deaths of animals for up to 18 months if we don't have these winter storms breaking it up.' University of Adelaide Microbial Ecologist Dr Christopher Keneally said even though 'you can't really see them,' algae blooms can have serious impacts on wildlife, and can even affect humans. 'Algae blooms have a massive impact on fish … they concentrate toxins – especially into shellfish – and cause a lot of damage,' he said. 'It's not as much of a problem for mammals like dolphins and human beings … but people in southern Australia have been noticing that there's a bit of eye irritation and throat and lung irritation that happens when they go out into the water when there's an algae bloom happening.' Dr Keneally stressed while we don't hear about it often, events like this are 'similar to a bushfire or other environmental catastrophes'. 'It can be quite scary when something like this happens, especially when you don't know what to expect … getting people used to the idea of it potentially happening in their own coastal waters is important when it comes to awareness.' 'The rapid mobilisation of Australia's research is going to be really important to forecasting these things and looking at mitigation in the future … we need to take action, or otherwise these things are going to become the new normal.' Shadow Water, Fisheries and Forestry and Emergency Management Minister Ross Cadell spoke to ABC Radio earlier this week about the emotional and economic impacts of algal blooms on local communities. 'You walk along the Ardrossan wharf and see garfish and King George whiting on the ground dying,' he said. 'You talk to the businesses and the Port Vincent gift shop is down (in sales) 15 per cent. 'The Stansbury caravan park, in the 48 hours before I got there, (had) 10-12 cancellations of November holidays because people are fearful of going in the water.' SA Premier Peter Malinauskas announced the Commonwealth government had provided a $14 million care package to South Australia which 'covers industry support, science and research, communications, community support and clean-up'. 'I want to thank the Commonwealth for their contribution … towards this effort,' he said 'We stand ready to deliver additional support if and when it is needed.'

Zac Brown: Veterans Voice Award
Singer-songwriter Zac Brown and his band's music has long resonated with soldiers and veterans of the U.S. military. In 2010, the Zac Brown Band participated in a tour in partnership with the USO, a non-profit providing many services to those who serve, including arts and entertainment. While performing several shows for troops in the Persian Gulf, the band filmed and used footage for a music video release of their introspective hit single, 'Free.' Over the years, Brown has developed personal relationships with the military community. One veteran in particular whom he is close with, Joe Maynard, has a favorite Zac Brown Band tune, the bluegrass-inspired 'Natural Disaster.' Maynard received a medal for saving fellow troops from an ambush while serving. He then gifted the medal to Brown as a token of appreciation for the positive impact the song had on himself and other veterans.
