A few hours ago NASA’s InSight lander was launched together with the two Mars Cube One nanosatellites from the Vandenberg base on an Atlas V 401 rocket. After about 1.5 hours they separated from the rocket’s last stage, called Centaur, and went en route to Mars.

The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission aims to investigate the geology of the planet Mars. A lander equipped with a seismometer, a thermal sensor and other instruments that will analyze the red planet’s internal structure. This will allow to obtain new data on its formation, also contributing to the existing models on the formation of rocky planets such as the Earth.

An article published in the journal “Nature Geoscience” describes a research on the possible rainfall that occurred on the planet Mars when it was young. Ramses Ramirez and Robert Craddock, two scientists who have been studying the red planet’s geological and climatic history for years, claim that about 4 billion years ago the climate could be warm and semi-arid with rainfall.

An article published in the journal “Geophysical Research Letters” describes a new analysis of data collected by NASA’s Galileo space probe during its flybys of Ganymede, one of Jupiter’s great moons. Glyn Collinson of NASA’s Goddard Space Flight Center and some colleagues reused the old flight software to process the data discovering new information on its magnetic field, in particular on its auroras and on the magnetic reconnection phenomena.

An article published in the journal “Nature Astronomy” describes a research on a region of space about 18,000 light years from the Earth in which a remarkable star formation is being observed, cataloged as W43-MM1. A team of researchers used the ALMA radio telescope to study it and found that more massive stars are forming than predicted by current models.
