Add rocket launches to Google, Apple or Outlook Calendar

One mission or a changing schedule

“Add to calendar” on a mission downloads one calendar entry. It is a snapshot. For an updating schedule, add one of the feed URLs below as a subscription in your calendar application. Opening a feed as an import can create a one-time copy instead.

Subscription addresses

Google Calendar on a computer

1. Copy one of the public HTTPS subscription addresses below.
2. Open Google Calendar in a computer web browser and sign in to the Google account you use on your devices.
3. Beside Other calendars, select +, then From URL.
4. Paste the feed address and select Add calendar.
5. Check the new calendar under Other calendars. On your phone, use the same Google account and enable that calendar in the app’s calendar list.

New URL subscriptions are added through the computer website, not the Google Calendar mobile app. Importing a downloaded .ics file creates a snapshot instead.

4. Tap Find, review the calendar details, then add or subscribe as prompted.

If a launch is missing or a date looks old

The date changed on Spacian but not in my calendar

Confirm that you subscribed by URL. A file import is a snapshot. Check the calendar’s refresh settings and compare the live mission page; the calendar provider controls refresh timing.

The feed opens as a download

Copy the HTTPS address into the calendar’s URL subscription field instead of opening the downloaded file.

A mission does not appear

Month-only or undated targets are omitted until a usable day is published. Day-only targets appear as all-day entries labelled time pending. Check your feed selection and whether the calendar is enabled.

I see duplicate missions

Check whether you both imported a file and subscribed to a feed, or subscribed to overlapping feeds. Remove the duplicate connection in your calendar app.

The launch appears on a different day

Timed entries use UTC instants and display in your calendar’s timezone. An event near midnight can fall on a different local day. Day-only entries remain all-day.

I changed my saved selection

A selection subscription contains the mission IDs selected when its link was created. Create a new subscription link after adding or removing saved missions; the existing selected missions can still receive target updates.

Check the mission page before launch day. A calendar subscription cannot guarantee an instant last-minute update.
