What space launch is happening today?

The launch schedule changes daily. A rocket can move up, slip hours or weeks, or be scrubbed minutes before liftoff due to upper-level winds, storms, ships in the safety zone, or an out-of-range sensor. That's why no static page can reliably say what's flying today; you have to check sources that update in real time. The good news is that the current pace is so high that a day rarely goes by without activity: SpaceX launches its Starlink batches several times a week, and China also keeps up a high cadence from Jiuquan, Xichang, Taiyuan, Wenchang, and sea-based platforms.

SpaceX publishes a list of upcoming missions on its website with date, time, and a link to the webcast. NASA maintains a calendar of its own launches and those of its partners, and its NASA+ service broadcasts flights carrying agency payloads. ESA and Arianespace announce Ariane 6 and Vega C launches from Kourou, and operators such as United Launch Alliance, Rocket Lab, and Blue Origin do the same. For a single combined view, independent aggregators exist that pull these sources together, but it's always worth confirming the time on the operator's website on the day itself.

Times are almost always given in UTC; in mainland Spain you add one or two hours depending on the season. Each launch has a "window," which can be instantaneous (for example, to reach the International Space Station) or last hours. A "scrub" means the attempt is called off and rescheduled, usually 24 hours later. And "NET" before a date (not earlier than) means the flight won't happen before that day, not that it will happen that day.
