What is MissionClock? Description of MissionClock

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.

MissionClock Pros

Mission Clock RocksIf you love NASA and all things rockets, you will really enjoy Mission Clock. It pops up and give you launch and countdown details, real time! Very, very cool!.Flying PoodlesVersion: 0

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..RandomUserOfYourAppVersion: 1.0.13

MissionClock Cons

Questioning reliabilityShows STS-130 in orbit and gives altitude, speed, and distance. However as of this moment, the shuttle is still on the launch pad! I think this app is more gimmick and bells and whistles then actually functions. One launch a few months ago, countdown clock showed T- minus 15 seconds, as I watched the shuttle come over the tree tops. Needs improving for sure..John ChilliVersion: 0

Disappointing time-keeping...The thing this app should do best is keep track of event times (IMO). That is does poorly. A very current example is the GRAIL LOI timing. at a little less than 4 hours from now will be the LOI for GRAIL-A and yet MissionClock is shown -10:44:04. Disappointing and way past the actual event time. Now it is showing launch 19hours ago of Afspc 4 that has not happened .. Useless..Timothy ChambersVersion: 1.0.13
