![]() This archived World Wind Java release has been migrated to GitHub from the World Wind Subversion server. The release 1.2 webinar slides are available for download. The bug database describes all such known problems. All other platform dependencies are related to specific problems, such as the existence of a bug on one platform but not another. The most significant one is the absence of BrowserBalloon availability on Linux. ![]() There are very few platform-specific dependencies. It is expected to work on Solaris but has not been tested on that platform. This release of World Wind operates on all platforms World Wind has historically supported: OS X, Windows 32 & 64, Linux 32 & 64. It also initiates a portal - that gathers into one place all information relative to understanding and using World Wind and its API. It’s undergone significant testing and contains important documentation that was missing from the previous “pre-alpha” daily releases. World Wind’s first public formal release. This release positions WorldWind Java to begin adding new functionality in the near future, please watch this repository for further updates. Removing deprecated functionality like WebStart, Applets and WebView.Discussions around the types of changes that need to be made when moving from 8 to 11 are broadly available on the Web. For example, setting the java library path system property. Creating work alike code to replace the use of unpublished JRE APIs that now throw an access exception.The package names for JOGL have changed although the API remains relatively consistent.Migrating to Java 11 and JOGL 2.4 went relatively smoothly. This situation has evolved over time and we are evaluating whether a Java 8 version of WWJ is desirable. ![]() The decision was made to upgrade WWJ to Java 11 based on questionable support options for Java 8 at the time. The prior release of WorldWind Java, v2.1.0, was compiled with Java 8. WorldWind's API remains largely unchanged in this release and we are committed to maintaining a consistent API in future releases. Deprecation of unsupported functionality such as Applets, WebStart and WebView.During this process some defects were addressed as well. We see more efforts like this from other satellite operators going forward.Īelous' deorbit campaign "paves the way for the safe return of active satellites that were never designed for controlled reentry," ESA's Peter Bickerton wrote in a July 19 blog post.The primary goal of the WorldWind Java (WWJ) v2.2.0 release is to modernize the SDK after a period of inactivity. And that appears to have gone mostly according to plan. One final maneuver occurred Friday, which was expected to set the stage for reentry about five hours later. The campaign picked up again Thursday (July 27), with four planned orbit-lowering maneuvers. On Monday (July 24), Aeolus performed two engine burns that lasted a total of 37.5 minutes and lowered its altitude by about 19 miles (30 km), to 155 miles (250 km). The spacecraft began falling from this orbit on June 19, and the mission team started accelerating the process five weeks later. ![]() Here's how ISS astronauts jettison old space station hardware (video)Īeolus studied Earth's winds from an altitude of about 200 miles (320 kilometers). Listen to music 'written' by doomed Aeolus wind-studying satellite (video) Satellite will die by fire as 1st-of-its-kind operation sends it plummeting down to Earth And the Aeolus team hopes to lead the way in this respect.Īeolus' reentry campaign "sets a new precedent for safe spacecraft operations and sustainable spaceflight, for both future missions and those already in orbit," ESA's Rosa Jesse wrote in a blog post last month. Guided reentries, which are commonly performed by rocket stages after orbital launches, could help make a dent in this space-junk problem. In terms of mass, we are speaking about 11,000 tons," Krag said at the July 19 press conference.Ībout 100 tons of human-made space junk fall to Earth each year, and large objects reenter our atmosphere about once a week on average, he added. "Today, we have 10,000 spacecraft in space, of which 2,000 are not functional. And there's a lot of stuff up there just waiting to come down. That threat, though small, is real whenever a satellite falls uncontrolled to Earth: In general, about 20% of a spacecraft's mass survives the fiery trip through the atmosphere and hits terra firma (or, more commonly, ocean waters). ![]()
