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.

This past year has been quite exciting year for the popups of private space companies. With the NASA budget decreasing, and looming budget issues within the US, privatization of space offers a glimmer of hope. I’m actually pretty excited to see how this pans out in the next few years.
Wired has a great overview of some of the private sector progress for space exploration.
It may be a few years before many of these things come to pass. In the mean time, here are some videos from a few of these companies to offer hope for future space exploration.

If you happen to be perusing the internet and want something to watch, NASA will be providing live commentary as the Gravity Recovery and Interior Laboratory (GRAIL) craft crashes (purposefully) into the moon today. The mission has mapped the moons gravitational field, and allowed scientists to get a better understanding of the interior structure of the moon. Read more here.
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.”

NASA has released information about some findings from the Curiosity mission. In a return from soil analysis, Curiosity detected water in addition to evidence of a simple carbon compound.
This is very exciting news, since carbon often leads to more complex organic materials. Now it will be a process of determining whether the carbon has come from Mars, or if it came from an outside source.
A few weeks ago it seemed the evidence was looking good. Voyager may have left the solar system, although it seems its not 100% official yet. The three things used to help classify whether it has left are increases in high-energy cosmic rays, a drop in charged sun particles, and a change in magnetic field. The high-energy cosmic rays and decrease in charged sun particles have been seen. It will be interesting to see what the data shows in the coming weeks.
NASA is in the process of getting a new space suit design for the Constellation program. The program aims to send humans deeper into space and eventually to Mars. Currently, there are two prototypes for new suits, a slimmer and maneuverable version launch and spacewalks, and a heavier suit for walking on the moon. The designs will allow for more protection and mobility in future missions to come.
Did you know that astronauts wear diapers under their suits during spacewalks?
