Learn
Follow a countdown, then print a page about the Moon, the station, or a paper rocket.
Eight moments in a real launch. Each one has a word to learn and a compliment that is actually about the work: the wait, the engines, the planned drop.
Follow a launchFive short packs. Each one says what is inside, then opens a page you can print.
$8
What’s inside. A one-page way to compare widths without pretending the distances fit on the page.
Open one-page preview$14
What’s inside. What the countdown words mean, and how to sit with a child without a fake “live” video.
Open one-page preview$7
What’s inside. A paper model of a two-stage rocket, plus three sentences on why the bottom falls off.
Open one-page preview$9
What’s inside. One page on distance, Apollo, Artemis II, and what has not happened yet.
Open one-page preview$6
What’s inside. How to look for the station, and what the people up there are actually doing.

A rocket is mostly propellant. When a set of tanks is empty, keeping those tanks means lifting dead weight. A stage — engines plus tanks — is dropped, and the next set lights. You see it in a launch video as a flash and a piece falling away. The payload is still on the top. Staging is not a failure. An engine that shuts down before its tanks are empty can be a failure, and only the flight commentary, or the company, can say which one you just watched.
Falcon 9 is the operational rocket. It flies crews, cargo, and Starlink. Its first stage lands and flies again. The second stage does not. Falcon Heavy is three Falcon cores. Starship is a different, much larger vehicle still in flight test. In September 2026 it reached orbit for the first time, deployed satellites, and ended the flight early. It is the vehicle NASA hopes to adapt as a lunar lander, after refueling tests that have not been finished. If a headline says “SpaceX rocket,” ask which one.
Artemis is NASA’s campaign to return crews to the Moon and, later, to practice for going farther. Artemis I tested Orion without a crew. Artemis II, in April 2026, flew four people around the Moon and home. A landing is a later mission and needs a lander as well as SLS and Orion. The program has partners, including the Canadian Space Agency on Artemis II. It is not a rebrand of Apollo, and this site is not part of it.
Start from the owner of the rocket. NASA crew and science flights are on NASA+ and NASA’s YouTube channel. SpaceX webcasts are on spacex.com/webcast and the company’s own posts. ESA uses its own web TV. A YouTube channel with “SpaceX live” in the name and no link from spacex.com is not the flight. Commentators on unofficial streams can be helpful or wrong. If a time changes, the official page already knows.
Our Space Mission is a reading site with a few original worksheets. It is not a school curriculum, and it is not an agency education office. Use it beside the agencies’ own pages. We are not those offices. The legal note says what we made and what we only link.
