Receive Alerts – ENS and LaRC Alert App

NASA LaRC Officials will use two critical tools – the Emergency Notification System and LaRC Alerts app – to communicate timely updates in case of an emergency,  weather event or shutdown. You’ll find everything that you need to know to get connected below.


Emergency Notification System (ENS)

The Emergency Notification System provides updates via text, email and phone. To add your or update your contact information to the system:


If you are a civil servant:

If you are a contractor:


Did You Know?


ENS email addresses for the primary and backup systems are now being routed through a address and will no longer display “[EXTERNAL]” in the subject.

Also, be aware that ENS calls come from area code 615. Once you’ve answered the call, saying “hello” will activate the message. Listen to the full message and follow the directions.


LaRC Alerts App

The LaRC Alerts app makes it easier for NASA Langley personnel and visitors to receive emergency notifications and puts important emergency contacts at your fingertips.

If you have downloaded the app, but are not receiving alerts, you’ll find helpful tips for troubleshooting iOS and Android devices below. If you have additional questions, contact us at

If you haven’t downloaded the app yet, we’ve also included the links to get you started at bottom of page.

Troubleshooting for iOS

If you do not see an expected alert listed within the LaRC Alerts app, please review your device’s notifications by swiping down from the top of the screen. From there, you can scroll through a history of all notifications received by your device that have not yet been viewed. LaRC Alert notifications can be identified by the app’s icon and name. If a LaRC Alert notification appears within the notification history, but not within the app, tap the notification for it to launch that alert with the LaRC Alerts app.

If you would prefer the app to automatically load alerts as they arrive (instead of manually tapping each individual notification), do not force close the app when you finish viewing an alert. Instead, click the home button to return to the home screen or use the app switcher to launch a different application. If the app is force closed, it will no longer be able to process incoming notifications in the background.

If no notifications are listed within the app or the device’s notification history:

Troubleshooting for Android

Check your notification settings on your Android device and verify that notifications are allowed for the LaRC Alerts app. The setting location may differ by device, but is typically found under Settings  –> Notifications  –> LaRC Alerts  –> Allow notifications. In addition, the app must be launched at least once after the initial install in order to register for notifications.

Verify that your device is connected to a network, either through Wi-Fi or a cellular network.

Do not “force stop” the app. Force stopping the app will also stop the background services necessary for processing incoming notifications. Please note that force stopping is not equivalent to exiting the application from your home, back or recent apps button; exiting the application from any of these standard buttons in Android will safely exit the application. However, if the app has been force stopped, relaunch the app by tapping the app icon from the home screen.

If the device is still not receiving notifications, launch the LARC Alerts app and tap the gear icon in the top right to open the LaRC Alert Settings. Tap Debug Options and on the following screen, tap Refresh FCM Registration. This process will re-send your registration token that is being used for push notifications to the service provider.

As an alternative, you may also try clearing the data stored by the LaRC Alerts app in order to renew the device’s registration with the push notification service. Please note that clearing app data will also clear all previously saved alerts. To continue, run the following steps:

  1. Stop the application if it’s running.
  2. Open the Application Manager (typically located under Settings  –> Apps) and tap the entry for LaRC Alerts.
  3. On the LaRC Alerts application info screen tap “Storage” and on the following screen tap the “Clear Data” button.
  4. Restart the LaRC Alerts app. The app should prompt you to accept the end-user license agreement and the app will re-register for notifications.

Downloading the App

Available for Android and Apple devices, LaRC Alerts will give you the latest notifications issued by NASA Langley’s center emergency management officials regarding emergencies, security situations, safety-related updates and weather conditions at the center.
