Curiosity rover eyes prominent mineral veins on Mars
Two-tone mineral veins at a site NASA’s Curiosity rover has reached by climbing a layered Martian mountain offer clues about multiple episodes of fluid movement. These episodes occurred later than the wet environmental conditions that formed lake-bed deposits the rover examined at the mountain’s base.
Race to detect gravitational waves intensifies
One of the great challenges in astrophysics is the detection of low-frequency gravitational waves — elusive ripples in the fabric of space-time caused by extremely energetic and large-scale cosmic events. To this end, the National Science Foundation (NSF) has awarded the North American Nanohertz Observatory for Gravitational Waves $14.5 million over 5 years.
