Today’s launch (June 4) of the Low Density Supersonic Decelerator aboard a high-altitude balloon has been cancelled due to weather. A line of rain showers developed overnight moving towards the launch site, which result in unstable wind conditions near the surface that would prevent the launch of the balloon. NASA will evaluate the next available launch opportunity, Friday, June 5.
