Jason-2, or the Ocean Surface Topography Mission (OSTM), is a joint venture between NASA's Jet Propulsion Laboratory, the US National Oceanic and Atmospheric Administration (NOAA), the French Space Agency (CNES) and the European Meteorology Satellite service (EUMETSAT).
"There's plenty resting on this satellite in terms of where our ocean and climate science is going," says Dr David Griffin, an oceanographer from the CSIRO Wealth from Oceans National Research Flagship and a member of the international Science Team which advises on satellite altimeter missions.
"Jason-2 provides a lifeline between space and some very significant science projects that are integral to our capabilities in understanding how the oceans are changing and particularly future ocean forecasting products," he says.
With an orbit 1336 kilometres above the Earth’s surface, Jason-2 will be one of three satellites equipped with special altimetry sensors to precisely measure sea level, and indirectly infer ocean heat content changes.
This information is also important for: Australia’s evolving ocean forecasting system, BLUElink; sea safety and offshore oil and gas operations; measuring global sea level rise; tracking large-scale ocean-atmosphere phenomena like El Niño and La Niña and marine mammals feeding in nutrient-rich ocean eddies; and forecasting currents for sports events such as the Sydney-Hobart yacht race.“Jason-2 provides a lifeline between space and some very significant science projects that are integral to our capabilities in understanding how the oceans are changing and particularly future ocean forecasting products,"
he says.High quality satellite altimetry started with the TOPEX/Poseidon mission (1992-2005), and continued with Jason-1 (2001-to the present). The altimeters measure sea surface height, from which we can estimate the strength and direction of ocean currents and also map sea level rise.Australian scientists contribute to the science mission in a number of ways, including calibration of the sensors on board the satellite. CSIRO Marine and Atmospheric Research, in conjunction with the University of Tasmania, the Bureau of Meteorology’s National Tidal Centre and Geoscience Australia has been running a calibration facility at Burnie (NW Tasmania) since 1992. This was enhanced by the deployment of a French transportable Satellite Laser Ranging (SLR) system at Burnie earlier this year. Burnie is the only absolute calibration site in the Southern Hemisphere. The other two main sites are off the coast of California, and in the Mediterranean Sea.
Australian science agencies using data from the new satellite include the Centre for Australian Weather and Climate Research – a partnership of CSIRO and the Bureau of Meteorology – and the Antarctic Climate and Ecosystem Cooperative Research Centre.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
