How's my landing page for a rocket launch calendar?

A few years back I made a script which would save rocket launches in my calendar so I could watch the livestreams. After thinking more about releasing my work into the wild lately I decided to make it available to the public and get some practice developing a landing page. The net result is Launch Cal (a working title).

I've added the link to the Google Calendar up first seeing as that's the primary action, but because I currently only support Google Calendar and not other formats for the full experience (it's a revival of a hobby project, not a full product). I've also added the ability further down the page to vote on one's favourite calendar application until I can conduct some proper market research - this because it gives me fewer reasons not to ship.

What do you all think of the UX and the layout? Is there anything I can add to improve it all? How about the email form? Other than notifying users when a new calendar format is supported and/or creating a mailing list, it has not real business being there.
