Hi there! It sounds really frustrating that the NASA app keeps flashing and then closing on your Macintosh. Let's work together to get this sorted out.

First, could you tell me if this issue started occurring after a specific update or change to your system? Also, have you tried any troubleshooting steps yet, like restarting your Mac or checking for updates to the app itself?

Once I understand more about the situation, I can guide you through some potential fixes!

The app is on my iPad, not my computer.

Thanks for clarifying that the issue is with the NASA app on your iPad! I understand how annoying it can be when an app doesn't work properly. Let’s go through some steps to try to fix this.

1. Restart Your iPad: Sometimes a simple restart can resolve temporary issues. Press and hold the power button until you see the slider, then slide to turn off. After it's off, hold the power button again to turn it back on.

2. Check for App Updates: Open the App Store and go to the “Updates” tab. Make sure the NASA app is updated to the latest version. If there's an update available, go ahead and install it.

3. Reinstall the App:
- First, delete the NASA app from your iPad by pressing and holding the app icon until it jiggles, then tap the "X" to delete it.
- Now, go to the App Store, search for the NASA app, and download it again.

4. Check iOS Updates: Ensure that your iPad is running the latest version of iOS. Go to Settings > General > Software Update. If there's an update, install it.

5. Check Storage Space: Sometimes, insufficient storage can cause apps to malfunction. Go to Settings > General > iPad Storage to see if you have enough space available. Clear out some space if necessary.

If you've tried these steps and the app is still crashing, there may be a deeper issue. We could explore that further, perhaps by checking for any known outages or glitches reported with the app recently. Let me know how these steps go!
