  1. The European Space Agency (ESA) has greenlit the development of the NanoMagSat constellation, marking a significant advancement in the use of small satellites for scientific missions. NanoMagSat, a flagship mission spearheaded by Open Cosmos together with IPGP (Université Paris Cité, Institut de physique du globe de Paris, CNRS) and CEA-Léti, aims to revolutionise our understanding of Earth's magnetic field and ionospheric environment. As a follow on from ESA's successful Earth Explorer Swarm mission, NanoMagSat will use a constellation of three 16U satellites equipped with state-of-the-art instruments to monitor magnetic fields and ionospheric phenomena. This mission is joining the Scout family, a programme from ESA to deliver scientific small satellite missions within a budget of less than €35 million. The decision to proceed with NanoMagSat follows the successful completion of Risk Retirement Activities including the development of a 3m-long deployable boom and a satellite platform with exceptional magnetic cleanliness, key to ensuring state-of-the art magnetic accuracy. ESA’s Director of Earth Observation Programmes, Simonetta Cheli, said of this news: “We are very pleased to add two new Scouts to our Earth observation mission portfolio. These small science missions perfectly complement our more traditional existing and future Earth Explorer missions, and will bring exciting benefits to Earth.”

  2. The 9.0 release add several new features, including a Google Maps source (finally!), improved WebGL line rendering, and a new symbol and text decluttering implementation. We also improved and broadened flat styles support for both WebGL and Canvas 2D renderers. For better developer experience, we made more types generic and fixed some issues with types. Backwards incompatible changes Improved render order of decluttered items Decluttered items in Vector and VectorTile layers now maintain the render order of the layers and within a layer. They do not get lifted to a higher place in the stack any more. For most use cases, this is the desired behavior. If, however, you've been relying on the previous behavior, you now have to create separate layers above the layer stack, with just the styles for the declutter items. Removal of Map#flushDeclutterItems() It is no longer necessary to call this function to put layers above decluttered symbols and text, because decluttering no longer lifts elements above the layer stack. To upgrade, simply remove the code where you use the flushDeclutterItems() method. Changes in ol/style Removed the ol/style/RegularShape's radius1 property. Use radius for regular polygons or radius and radius2 for stars. Removed the shape-radius1 property from ol/style/flat~FlatShape. Use shape-radius instead. GeometryCollection constructor ol/geom/GeometryCollection can no longer be created without providing a Geometry array. Empty arrays are still valid. ol/interaction/Draw The finishDrawing() method now returns the drawn feature or null if no drawing could be finished. Previously it returned undefined. page: https://github.com/openlayers/openlayers/releases/tag/v9.0.0
