Track The Sky is a real-time 3D satellite tracker that follows over 9,000 satellites on an interactive 3D globe using live orbital data. It covers categories including space stations, Starlink, GPS and weather satellites. Features include clickable orbit paths, ground tracks, altitude and velocity, and overhead pass predictions.
SQL Easy is a free interactive SQL tutorial offering 31 exercises that run against a real SQLite database in the browser. It provides hints when users are stuck and immediate feedback when a query is correct, and requires no signup. It is built by the team behind Beekeeper Studio.
Corca is a collaborative math editor. It lets users type mathematical expressions without syntax or coding, with input behaving like search. Multiple people can work on math together in real time, and equations export to LaTeX for copying or document download.
An interactive 3D visualization of NASA meteor shower data that shows meteoroid streams orbiting the Sun and Earth passing through them. The page also includes notes on seeing showers, an iframe embed option and mention of the SpaceKit.js engine.
The Japan Aerospace Exploration Agency (JAXA) is an organization that performs various activities related to aerospace, from basic research in the aerospace field to development and utilization. Its site covers missions including XRISM, SLIM, LUPEX, GOSAT-2, BepiColombo, and the H3 and Epsilon launch vehicles, along with press releases and international activities.
ShadeMap is an online tool that simulates sun shadows for any date and time at any place on Earth. It simulates shadows cast by buildings, trees and terrain in 3D and can generate shadow accumulation and shadow accrual maps. The service runs online without installing or buying Google Earth Pro.
Lightyear.fm is a browser-based visualization that depicts radio broadcasts leaving Earth at the speed of light and traveling outward into space. Scrolling away from Earth shows how far past hits have traveled, with more distant points carrying older music. It includes planet and star data and notes that many stars were removed for display purposes and radii are not accurate.
