New Zealand company Rocket Lab's launch of a 17-metre-long rocket from Māhia Peninsula was aborted at the last moment this afternoon.
The test flight - which is nicknamed 'Still Testing' - was set to launch at 4.50pm.
The launch was aborted two seconds before take-off.
Rocket Labs staff have now confirmed there will be no further attempt today, while they review the data of the failed launch.
Rocket Labs said the vehicle performed a "safe auto-sequence abort".

The company opened the 10-day launching window on Friday, but high winds had prevented the launch until today.
It is the second of three test flights as the company prepares to become a commercial operation.
Currently targeting no earlier than 16:00 NZDT (3:00 UTC) for #StillTesting launch attempt. Weather looking good, but we're continuing to monitor. Webcast can be viewed at https://t.co/iHjDAlywqX.
