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 1.1.6
This minor update addresses some issues revealed in the last update:

• Enhancements across the app to better support Dark Mode as well as Dynamic Type.
• Larger text (where possible) in the Clocks tab and the bottom-edge clock banner.
• Override the system settings for Dark Mode (for example, if you normally prefer Light Mode but wanted MissionClock to be Dark).
• Fix a bug in how missions are selected for the Clocks tab.
Our verdict: Good
  • + MissionClock is a highly rated app (4-star).
  • + MissionClock is currently ranked #35 in paid News apps for iPhone, as well as #22 in paid News apps for iPad.
