Ultima revisao: 2026-07-21

Abra o Apollo Free-Return Trajectory 3D Explorer quando precisar comparar free-return e hybrid no sobrevoo lunar - sem um projetista patched-conic.

Licao de seguranca da tripulacao

Comece em Free-return, va ate o sobrevoo e mude para Hybrid para mostrar por que a Apollo 13 precisou da queima DPS-1 de 34.23 s apos a falha do tanque de oxigenio.

Figuras de distancia da Apollo 13

Aqui cabem 400,171 km no PC, ~250 km de altitude lunar no free-return restaurado e ~2,500 nmi de perigeu hybrid sem captura.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
