16 July 2020 PR084-2020 ESA RELEASES FIRST IMAGES FROM SOLAR ORBITER The European Space Agency (ESA) has released the first images from its Solar Orbiter spacecraft, which completed its commissioning phase in mid-June and made its first close approach to the Sun. Shortly thereafter, the European and U.S. science teams behind the mission’s ten instruments were able to test the entire instrument suite in concert for the first time. Despite the setbacks the mission teams had to contend with during commissioning of the probe and its instruments in the midst of the COVID-19 pandemic, the first images received are outstanding. The Sun has never been imaged this close up before. During its first perihelion, the point in the spacecraft’s elliptical orbit closest to the Sun, Solar Orbiter got to within 77 million kilometres of the star’s surface, about half the distance between the Sun and Earth. The spacecraft will eventually make much closer approaches; it is now in its cruise phase, gradually adjusting its orbit around the Sun. Once in its science phase, which will commence in late 2021, the spacecraft will get as close as 42 million kilometres, closer than the planet Mercury. The spacecraft’s operators will gradually tilt its orbit to get the first proper view of the Sun’s poles. Solar Orbiter first images here Launched during the night of 9 to 10 February, Solar Orbiter is on its way to the Sun on a voyage that will take a little over two years and a science mission scheduled to last between five and nine years. -

A Map of Saturn's Largest Moon
News in focus conducted in Guinea towards the end of the 2014–16 Ebola outbreak in West Africa. There, the vaccine was administered to people who had been in contact with someone who was infected with Ebola, and to their subsequent contacts. It was found to offer a high level of protection against infection. Health workers have used this strategy — known as ring vaccination — in the two other outbreaks in which rVSV-ZEBOV-GP had been deployed. But Heymann says it’s important to determine whether the Merck vaccine has other uses — for instance, preventive admin- istration to emergency health workers who might encounter Ebola in the distant future. For this, researchers will need to determine how long the vaccine’s protection lasts, and whether a ‘booster’ dose can extend HTTP://DOI.ORG/DFB8 (2019) HTTP://DOI.ORG/DFB8 immunity. Such studies are in the works with rVSV-ZE- BOV-GP and competing vaccines, says Adrian Hill, a vaccinologist at the University of Oxford, NATURE ASTRON.
