Portugal's first hypersonic test reached Mach 25, heating gas beyond the Sun’s surface temperature.
Portugal successfully conducted its first hypersonic test on November 19, 2025, achieving speeds of about eight kilometers per second—Mach 25—using the ESTHER facility at Lisbon’s Instituto Superior Técnico.
The experiment generated shock waves heating gas beyond the Sun’s surface temperature, producing luminous effects like shooting stars.
It marks Portugal’s entry into advanced hypersonic research, supporting future space missions and aerospace development.
