After nearly eight years traveling through the inner solar system, the trailblazing BepiColombo spacecraft has finally begun its arrival at Mercury.
The joint European Space Agency (ESA)-Japanese Aerospace Exploration Agency (JAXA) mission reached a major milestone today (Sep. 3), entering its arrival phase at one of our sun's least-studied planets. BepiColombo's Mercury Transfer Module (MTM), the main power and propulsion system that has ferried a dual stack of planetary probes through space for nearly eight years, released its payload to kick off a sequence of operations that will ultimately place the two spacecraft in Mercury's orbit.
The separation left ESA's Mercury Planetary Orbiter (MPO) and JAXA's Mercury Magnetospheric Orbiter, known as Mio, together for their final approach, which will take about six more months. "It will basically be a new mission starting today," said Bruno Sousa, ESA's head of operations definition and engineering, during today's mission livestre...
