At least 20 people were killed and more injured when a rocket exploded at the Brazilian Alcantara Launch Center. One of the VLS-3 rocket’s engines is believed to have caught on fire, triggering an explosion that caused the launch pad to collapse. The two research satellites atop the rocket were also destroyed. This disaster is just the latest in a series of setbacks which have plagued the Brazilian rocket launch program – two rockets in 1997 and 1999 had to be destroyed shortly after take off.
