Digital Trends: Browse hundreds of images of Mars captured by ESA’s Mars Express webcam. “If you’ve ever wanted to get a close-up look at Mars, the European Space Agency (ESA) has just released a treasure trove of images. Captured by the Visual Monitoring Camera (VMC) instrument onboard the Mars Express orbiter, these images come from data captured between 2007 and this year, in addition to observations of the release of the Beagle 2 lander in 2003.”
New Atlas: Track spacecraft as they talk to Earth in real time with new ESA tool. “The European Space Agency has released a new tool that allows space enthusiasts to track their favorite missions in real time as they communicate with ground stations back on Earth. The service provides a range of information on spacecraft and antennae, including how long it takes for a signal to travel between the two, and the distance that separates them.”
New Atlas: ESA completes massive archive of Rosetta images and data. “The European Space Agency (ESA) has completed a massive publicly-available archive of images and data collected over the course of the historic Rosetta mission.”
New Scientist: Biggest ever 3D map of the galaxy pinpoints 1.7 billion stars. “We’re building a map of our galaxy, one star at a time. The European Space Agency’s Gaia satellite orbits Earth 1.5 million kilometres away, staring at millions of stars every day to make a 3D map of our galaxy. On 25 April it released its second batch of data. In 2016, Gaia first released data from its star catalog spanning 14 months of constant observation. It included information about the brightness and positions in the sky of 1.1 billion stars, and more detailed data on the distances and motions of the brightest two million of those. This new data release is even more robust, covering another 22 months of observation time. It includes more stars than the first release, and the colours, temperatures, and radii for some of those stars.”
From the ESA (European Space Agency): ESA Affirms Open Access Policy for images, Videos and Data. “ESA today announced it has adopted an Open Access policy for its content such as still images, videos and selected sets of data. … In particular, a new Open Access policy for ESA’s information and data will now facilitate broadest use and reuse of the material for the general public, media, the educational sector, partners and anybody else seeking to utilise and build upon it.”
The ESA Planetary Science Archive has gotten a new look. ESA stands for European Space Agency. “ESA launches a new version of its Planetary Science Archive (PSA) website, the online interface to data from the agency’s space science missions that have been exploring planets, moons and other small bodies in the Solar System. With a new design and enhanced search functionalities, the platform now provides a direct and simple access to the scientific data, helping scientists to discover and explore the archive content.”
The European Space Agency has released its first data in its project to build an atlas of one billion stars. “Mission manager Fred Jansen told a news conference in Madrid that the project has already collected some 500 billion measurements and he is ‘extremely happy’ with the precision of the data. It is being distributed among scientists for analysis. At the heart of the five-year mission is the 10-metre-wide Gaia spacecraft, which resembles a barrel sitting on a silver saucer. It carries two telescopes and is orbiting slowly around the sun.” The data are also available online.
