This past Thursday the Federal Aviation Administration (FAA) has announced the authorization of SN15, SN16, and SN17 launches, which are spacecraft of SpaceX.
SpaceX made a few changes to the launch vehicle that needed to be approved by the FAA. Some of these changes mitigate any risk to the public that the launches may entail.
The FAA said they will verify that SpaceX put in corrective measures needed following the SN11 mishap.
Last March, SpaceX launched SN11 in foggy conditions and it exploded sometime during the experiment at which point debris scattered throughout the area.
According to the FAA, they continue investigating the SN11 mishap.
