Hi all,
 I hope everything is going well, it is amazing to me how fast time goes….I have been getting allot of speaker requests for the Great American Teach-In on Nov 17th…..I am already committed to that day but would be happy to visit on another day or even earlier in the month so you could focus on all the events preparing for the 17th….please let me know so we can schedule the visits….NASA continues to develop the program to send astronauts to Mars with projected testing and missions preceding the actual launch…..we must always remember to do our best, enjoy everything we do, make each day special, let those we care about most know, be appreciative of the good in our lives, smile & have fun! Gabe

Journey to Mars Overview
NASA is on a journey to Mars, with a goal of sending humans to the Red Planet in the 2030s. That journey is already well under way.

For more than 40 years, the agency and its partners have regularly sent orbiters, landers and rovers <http://www.nasa.gov/mars>, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Curiosity rover <http://www.nasa.gov/mission_pages/msl/index.html> has gathered radiation data to help us protect future astronauts, and the upcoming Mars 2020 rover <http://mars.nasa.gov/mars2020/> will study the availability of Martian resources, including oxygen.

There is more to learn as we expand humanity's presence into the solar system: Was Mars once home to microbial life or is it today? Can it be a safe home for humans? What can the Red Planet teach us about our own planet's past, present and future?

Building on the robotic legacy, the human exploration of Mars crosses three thresholds, each with increasing challenges as humans move farther from Earth: Earth Reliant, the Proving Ground, and Earth Independent.

Earth Reliant exploration is focused on research aboard the International Space Station <http://www.nasa.gov/station>. The orbiting microgravity laboratory serves as a world-class test bed for the technologies and communications systems needed for human missions to deep space. Astronauts are learning about what it takes to live and work in space for long periods of time, increasing our  understanding of how the body changes in space and how to protect astronaut health.

We're also working with our commercial crew and cargo partners to provide access to low-Earth orbit and eventually stimulate new economic activity, allowing NASA to continue using the station while preparing for missions beyond.

Next, we move into the Proving Ground, conducting a series of missions near the moon  -- we call it "cislunar space" -- that will test the capabilities we will need to live and work at Mars. Astronauts on the space station are only hours away from Earth, but the proving ground is days away, a natural stepping stone to a Mars mission, which will be months away from home.

The first of these missions is set for November 2018, when NASA's powerful new rocket, the Space Launch System <http://www.nasa.gov/sls>, will launch from NASA’s Kennedy Space Center in Florida. The mission, Exploration Mission-1 (EM-1) <https://www.nasa.gov/feature/the-ins-and-outs-of-nasa-s-first-launch-of-sls-and-orion>, will carry the Orion <http://www.nasa.gov/orion> spacecraft (without astronauts) thousands of miles beyond the moon during an approximately three week mission. Next up, astronauts will climb into Orion for a similar mission, traveling farther than humans have ever traveled before. (Watch Video: Exploration Mission-1 <https://www.youtube.com/watch?v=Mo8IkHM8fGE>).

Also in the 2020s, we'll send astronauts on a yearlong mission into this deep space proving ground, verifying habitation and testing our readiness for Mars.

Another proving ground milestone is the Asteroid Redirect Mission <http://www.nasa.gov/arm>. NASA will send a robotic spacecraft to capture an asteroid boulder and put it in a safe orbit around the moon. Astronauts on Orion will then explore the asteroid, returning to Earth with samples. This two-part mission will test both deep space spacewalking and sampling techniques and Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars.

Hubble Peers Into the Heart of the Milky Way Galaxy
 <http://www.nasa.gov/sites/default/files/thumbnails/image/hubbleimage1p1611a1r.jpg>
Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy. So packed with stars, it is equivalent to having a million suns crammed between us and our closest stellar neighbor, Alpha Centauri. At the very hub of our galaxy, this star cluster surrounds the Milky Way’s central supermassive black hole, which is about 4 million times the mass of our sun.

This is fascinating......
NASA, ESA Telescopes Give Shape to Furious Black Hole Winds

Supermassive black holes at the cores of galaxies blast out radiation and ultra-fast winds, as illustrated in this artist's conception. NASA's NuSTAR and ESA's XMM-Newton telescopes show that these winds, containing highly ionized atoms, blow in a nearly spherical fashion.

Space Station Flight Over the Southern Tip of Italy

The southern tip of Italy is visible in this image taken by the Expedition 49 crew aboard the International Space Station on Sept. 17, 2016. The brightly lit city of Naples can be seen in the bottom section of the image. A Russian Soyuz spacecraft can be seen in the foreground.
