Astronomy & Space news

	China targets 2020 Mars mission launch: official China plans to send a rover to Mars to explore the Red Planet, a top space official announced on Friday, in the latest step of its ambitious space programme.
	New Herschel maps and catalogues reveal stellar nurseries across the galactic plane ESA's Herschel mission releases today a series of unprecedented maps of star-forming hubs in the plane of our Milky Way galaxy. This is accompanied by a set of catalogues of hundreds of thousands of compact sources that span all phases leading to the birth of stars in our Galaxy. These maps and catalogues will be very valuable resources for astronomers, to exploit scientifically and for planning follow-up studies of particularly interesting regions in the Galactic Plane.
	Image: Tracking asteroid Heinerklinkrad The US Minor Planet Center has announced the new name for the asteroid formerly known as 2009 RC26 to be (264045) Heinerklinkrad.
	Gene analysis system could accelerate pace of research on the space station Biologists around the world routinely perform gene expression analysis to better understand living systems. Gene expression analysis examines the types and amounts of molecules produced by genes in living cells, telling us which genes are active and which are inactive at a given point in time. This reveals valuable information about the highly dynamic internal states of cells in living systems. NASA's WetLab-2 hardware system is bringing to the International Space Station the technology to measure gene expression of biological specimens in space, and to transmit the results to researchers on Earth at the speed of light.
	NASA works to improve solar electric propulsion for deep space exploration NASA has selected Aerojet Rocketdyne, Inc. of Redmond, Washington, to design and develop an advanced electric propulsion system that will significantly advance the nation's commercial space capabilities, and enable deep space exploration missions, including the robotic portion of NASA's Asteroid Redirect Mission (ARM) and its Journey to Mars.
	Constructing James Webb Space Telescope's twin for Goddard's 'biggest' thermal test Crouching low beneath the underbelly of the behemoth James Webb Space Telescope "observatory core" test model, surrounded by critical test hardware, a technician toiled for hours wrapping the replica's surfaces in delicate thermal blankets and strips of Mylar.
	Image: Pluto's 'halo' craters Within Pluto's informally named Vega Terra region is a field of eye-catching craters that looks like a cluster of bright halos scattered across a dark landscape.
	Our sun may have eaten a super-Earth for breakfast Our solar system sure seems like an orderly place. The orbits of the planets are predictable enough that we can send spacecraft on multi-year journeys to them and they will reliably reach their destinations. But we've only been looking at the solar system for the blink of an eye, cosmically speaking.
	Cosmic beacons reveal the Milky Way's ancient core An international team of astronomers led by Dr. Andrea Kunder of the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany has discovered that the central 2000 light years within the Milky Way Galaxy hosts an ancient population of stars. These stars are more than 10 billion years old and their orbits in space preserve the early history of the formation of the Milky Way.
Lens used during Apollo mission sells for more than $450,000 A camera lens used during the Apollo 15 space mission in 1971 has been sold at auction for more than $450,000.
	NASA seeks industry ideas for an advanced Mars satellite NASA is soliciting ideas from U.S. industry for designs of a Mars orbiter for potential launch in the 2020s. The satellite would provide advanced communications and imaging, as well as robotic science exploration, in support of NASA's Journey to Mars.
Is there anybody out there? On the quest for extraterrestrial life Leiden Professor of Astronomy Mike Garrett is searching for signs of extraterrestrial intelligence. In his Kaiser lecture on 23 April he will discuss how far science has progressed in this quest.
	What is the surface of Neptune like? As a gas giant (or ice giant), Neptune has no solid surface. In fact, the blue-green disc we have all seen in photographs over the years is actually a bit of an illusion. What we see is actually the tops of some very deep gas clouds, which in turn give way to water and other melted ices that lie over an approximately Earth-size core made of silicate rock and a nickel-iron mix. If a person were to attempt to stand on Neptune, they would sink through the gaseous layers.

Older adults need better blood pressure and cholesterol control to prevent cardiovascular disease The leading cause of death in the elderly, the fastest growing segment of the population, is cardiovascular disease (CVD). Prevention of cardiovascular events in elderly patients presents a therapeutic challenge because this age group is generally underrepresented in clinical trials, and doctors often assume that it is too late to initiate preventive therapy in the elderly. A review by clinical experts of the best available evidence concluded that cholesterol-lowering and blood pressure-controlling therapy are the most effective treatments for reducing cardiovascular events in older adults, but that treatment needs to be individualized, reports the Canadian Journal of Cardiology.
