The Mars Rover Curiosity’s activity was temporarily stopped due to an electrical anomaly that happened on February 27, 2015. During the transfer of dust samples just taken from a drill using the robotic arm, the fault protection system was triggered. The telemetry data sent by Curiosity indicated that there was a short circuit and for this reason its activity was stopped.
NASA’s space probe Dawn continues its approach to the dwarf planet Ceres. This allows to send on Earth better and better photographs with greater details of its surface. The previous images were clear enough to make it possible to see some light-colored areas and in particular a really bright one, which had puzzled scientists. A photo taken on February 19 at a distance of about 46,000 km (about 29,000 miles) shows a second bright area close to the one already identified.
NASA’s MAVEN space probe successfully completed the first of five deep-dip maneuvers into the depths of Mars atmosphere. The purpose was to gather measurements closer to the lower limit of the upper layer of the red planet’s atmosphere. The periapsis, which is the lowest altitude point of the orbit, reached by MAVEN was 125 kilometers (78 miles).
The purpose of the space probe MAVEN (Mars Atmosphere and Volatile Evolution), which reached the orbit of Mars on September 21, 2014, is precisely to study the red planet’s atmosphere. It’s much thinner than Earth’s one but is still a complex system. To understand its dynamics and its evolution over time, MAVEN is making continuous measurements and during the month started plunging into its depths.
NASA’s Dawn spacecraft is approaching the dwarf planet Ceres. On February 12, 2015, when it was at a distance of about 83,000 kilometers (about 52,000 miles), it took some pictures that show us Ceres with a quality never seen before, allowing us to see its craters. The photos taken previously had puzzled scientists for the presence of some white spots but the new images don’t solve the mystery.
Yesterday, NASA released the first photographs of the dwarf planet Pluto and its main satellite Charon taken by the space probe New Horizons after its awakening. The spacecraft was still over 200 million kilometers (about 126 million miles) away from Pluto but February 4, 2015 was the 109th anniversary of the birth of Clyde Tombaugh, who in 1930 discovered the dwarf planet. A small portion of Tombaugh’s ashes were placed aboard New Horizons.
