NASA Live

NASA Live is the agency's hub for live video. When events are on, it streams launches, spacewalks, mission briefings and views from the International Space Station, and when they are not, there may be little or nothing live, so check the schedule before you settle in. When it is working, it is a front-row seat to space exploration: you watch the same coverage the rest of the world does, with the commentary of the people who are running the mission. It is an easy habit to build around a launch day, and a nice contrast to the quiet browsing on most of this list. The site is run by NASA, and it works on phones and desktops. Coverage comes and goes, so treat it as an event destination rather than a constant feed. Tip: look at the schedule a day ahead and put the event you care about in your calendar. If you want something calmer, the live animal cams on our list are always on in daylight.
