A NASA image of Mars from the Hubble Space Telescope
The NASA mission to mars, MAVEN (Mars Atmospheric and Volatile EvolutionN), will be launching in a little over a week on November 18. This very exciting mission is going to investigate what happened to Mars’s atmosphere. It is thought that at one time the atmosphere was dense enough to support water on the surface of Mars. The mission will give clues about whether Mars could have supported life at one time. MAVEN will take 10 months to reach the planet of Mars.

Recently I wrote about recent talk of the changes that voyager 1 has been seeing as it reaches the outer edges of the solar system. There are three things that would help determine an exit from the solar system which include an increase in cosmic particles, a decrease in charged sun particles and change in the magnetic field.
While there have been decreases in sun charged particles and increases in cosmic particles, there hasn’t been a flip in the magnetic field. Scientists now think that voyager is in a newly discovered region in the edges of the solar system where interstellar magnetic field lines are connected with the sun. In this area, particles from inside the heliosphere are leaving, while cosmic particles are quickly entering the heliosphere replacing the lost particles. This area has been dubbed the “magnetic highway.”
