The Mars Express orbiter, the European Space Agency's (ESA) first interplanetary mission, entered orbit around Mars on June 2nd, 2003. Since then, the probe has mapped the Martian surface using its High-Resolution Stereo ...
Multiple missions are destined for the moon in this decade. These include robotic and crewed missions conducted by space agencies, commercial space entities, and non-profit organizations. The risks and hazards of going to ...
Through the Artemis Program, NASA plans to send the first astronauts to the moon in over 50 years. Before the decade is over, this program aims to establish the infrastructure that will allow for a "sustained program of lunar ...
Located near the summit of Maunakea, Hawaii, the 15-meter (~49 ft) James Clerk Maxwell Telescope (JCMT) at the East Asia Observatory (EAO) is the largest telescope in the world designed to operate exclusively in the submillimeter-wavelength. ...
A lot has changed since the last Space Age. Unlike the days of Sputnik, Vostok, Mercury, and Apollo, the current era is not defined by two superpowers constantly vying for dominance and one-upmanship. More than ever, international ...
