Keep up-to-date with space launches from NASA and other agencies around the world with MissionClock for your iPhone or iPod Touch.

MissionClock shows you a real-time countdown clock for upcoming missions, as well as information about missions that are currently underway. You can see major launch and ascent events as they happen, and receive alerts when mission conditions change.


• Gorgeous, at-a-glance countdown information
• T-clock and L-clock information
• Countdown holds
• Hold time remaining
• Current and significant event times displayed in multiple time zones
• Detailed mission event lists
• Time to/since each event

MissionClock’s main view shows the current time in three time zones (yours, UTC, and the mission’s). It shows the T-clock, including pauses for built-in launch holds, and the L-clock, letting you know how much real time remains before launch. For missions that have already launched, MissionClock will show you the Mission Elapsed Time (MET).

The MissionClock staff regularly compile space mission information from a variety of sources including contacts within NASA, and collect them on our servers. MissionClock is automatically updated with changes, so you stay informed.

What's New in Version 1.0.13

Fixed a crash that occurs if no pending launches are in the local mission database.

Customer Reviews

Very Cool! More detail than you probably every need!

This is slick. All sorts of details. I was really hesitant to spend the $4.99 for it but I had heard that he specifically has to make changes by hand as NASA changes timelines.

This has PUSH alerts, that means you can get them even when not running the application. And it looks like it keeps track of the push alerts so you can view them later, which is very nice.

I'm a pretty techie guy but the info is pretty geeky even for me. It needs a "basic mode" for the less geeky, but interested people. (Honestly, I'd probably use that mode).

Two complaints (but I'm still giving this 5 stars):

1) In the application, the mission clock pages needs to be linked to the missions page. Clicking the clock title (or something) should take me to the mission page for that mission and clicking the events at the bottom of a clock page should take me to all the events for that mission. They're all there already, they're just too many clicks away.

2) When I get an alert/message I want to be able to click on it and get the clock to quickly pop up. Sometimes the name in the alert doesn’t match the name in the list of missions.

There's info on past missions too. The only difference is the clocks aren't ticking....

Maybe some definitions for some of the information or links for more info on the launches (more than what's the overview page).

Links to NASA TV to watch? To stream audio?

Great detail. It's been stable for me.

General tip for all apps if you're seeing app crashes, update your iOS. I haven't seen crashes with this app, and I keep iOS up to date.

I've been showing some NASA TV to my daughter, and she is fascinated with the missions and how they do work on the ISS. This app brings another level of detail, with the event listings and times of each event for each mission. The info is updated regularly.

It's great that some recent past missions are listed too. The information seems pretty technical, obviously with some NASA jargon, but it's actually fun to see that.

One great thing is the push notifications for major events. If there's a scrub or other big news it alerts you even if you aren't running the app at the time.

Contrary to what one review stated, this app is definitely tracking all the major launches.

Great app lacking an update

Overall a great app. I live in Central Florida and routinely use this app to track the launch schedule before going outside to watch the rockets streak across the sky. Noticed some launches slightly off or missing lately. Also desperately needs to be upgraded to support the iPhone 5 resolution.
