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. Features: • 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.



  • Great app

    By osvaldoapmarques
    About the app Mission Clock it's a fantastic app I like to use it and check the reports about the lunches ... One Suggestion could be - add to the app a search field for the satellite name ! to access the date of the lunch by the satellite name . I am looking at the moment for the lunch time for the Es'hail 2 and it's hard to find in Google ... It could be great to find it in Mission Clock .
  • Awesome!!

    Awesome update. Long time user of this app. It's great to have push notifications back.

    Space fans definitely need this app. The developers always listen to users and are swift to fix issues with the app especially when you consider its free It's so good I'd pay a nominal charge to ensure it keeps going
  • Almost great, but not

    By JCHHenderson
    Could be excellent but it's super frustrating when a mission is delayed and the times are not altered.
  • Great app but needs updating to retina

    By shades846
    Great app with a lot if info on the latest rockets etc. though it needs updating for retina displays.
  • Awesome app for keeping up with what goes up!

    This app does EXACTLY what it says on the tin. If you want to know what humanity is chucking into orbit then this app is perfect, with accurate info and brilliant alerts that keep you in the loop even when you can’t get online to watch them. Plus it’s super easy to use, even if it is rocket science! Love it! :)
  • Very impressed!

  • Great app

    This is a great app but did notice today that the countdown was a few seconds faster than the official time shown on the live feeds. But otherwise great!

    Now even creamier with proper iPad support! NOTE TO LATENCY ZERO: I tried using your contact form on your website to report this, but it doesn't work. I realise that this basic iPad support is interim but if at all possible could you make 1 quick change? I keep my iPad in a cradle, but it has to go in upside down in order to plug the cable in. I realise it's extra work to add landscape support (which would be ideal) - but enabling the upside down portrait orientation would definitely suffice for now. Thanks!
