Hi everyone,

 I know it has been a while but also know many of you were winding down your school’s year…I’m sure everyone is enjoying summer...I had such an amazing time in Brazil….I not only participated in The Campus Party Brasilia, which was so amazing…so much going on, thousands at so many events but also went to the University of Brasilia, speaking with about 300 aeronautical engineering students…they were awesome…It was so much fun to spend time with them, then they showed me the campus and school projects…A Dragon supply ship owned and operated by SpaceX departed the International Space Station early Monday, July 3rd, and returned to Earth for a predawn splashdown in the Pacific Ocean southwest of Los Angeles with scientific specimens and other equipment... we also had a great launch...A SpaceX Falcon 9 rocket rumbled into the sky Wednesday from NASA’s Kennedy Space Center in Florida, flexing the rocket’s muscles and lofting a massive Intelsat satellite to orbit supporting wireless communications, television broadcasting and trans-Atlantic data relays….there is always so much going on in space exploration…I hope you can share it with your students, friends, & family…we must always remember to do our best, enjoy everything we do, live in the present, make each day special, let those we care about most know, be thankful for the good in our lives, smile and have fun....gabe

20 years exploring Mars….



NASA’s Mars Pathfinder probe dropped to the surface of Mars for an airbag-cushioned landing 20 years ago Tuesday, bouncing 15 times across an ancient flood plain before deploying a mobile robot to usher in two decades of uninterrupted Martian exploration. The Independence Day landing in 1997 was the first touchdown of a robot on Mars since NASA’s Viking landers arrived in 1976, and the U.S. space agency has since maintained a continuous robotic presence at the red planet, dispatching additional landers, rovers and orbiters to sample rocks, monitor Martian weather, and glimpse into the world’s warmer, wetter past.



NASA's Cassini probe <https://www.space.com/30945-inside-cassini-s-multi-year-saturn-mission-infographic.html> has now been circling Saturn for 13 years.

Cassini arrived in orbit <https://www.space.com/26364-cassini-reaches-saturn-mission-control-flashback-video.html> around the ringed planet on the night of June 30, 2004 (July 1 GMT), after a nearly seven-year journey through deep space. That trip, which kicked off with a launch atop a Titan IVB rocket on Oct. 15, 1997, covered a total of 2.2 billion miles (3.5 billion kilometers), NASA officials have said. The journey featured Venus flybys in April 1998 and June 1999, an Earth encounter in August 1999, and a Jupiter flyby in December 2000.



NASA Invites Public to Celebrate 100 Years of Aerospace Breakthroughs
NASA invites the public to three days of discussion and storytelling with notable aerospace experts to mark the 100th anniversary of the agency’s Langley Research Center in Hampton, Virginia. Portions of the event will air live on NASA Television and the agency’s website <https://www.nasa.gov/live>. The Langley Centennial Symposium will be held July 12-14 at the Hampton Roads Convention Center, and admission is free. Media wishing to attend should contact Michael Finneran at 757-864-6110 or michael.p.finneran at nasa.gov <mailto:michael.p.finneran at nasa.gov>. Keynote speakers include Jean-Yves Le Gall, president of France’s space agency, former NASA Deputy Administrator Dava Newman, and representatives from NASA, related government organizations, industry and academia.

Panel and presentation topics include:
Hidden Figures: The Story Behind the Story
The History of Flight: A Century of Finding Practical Solutions
International Partnerships to Reach New Heights, Reveal the Unknown, and Benefit All Humankind
The Future of NASA
Aerospace in the Next 20 to 30 Years

A planetary-mass object the size of Mars may be lurking in the outer solar system. 


A planet-size object may be orbiting the sun in the icy reaches of the solar system beyond Pluto. Scientists at the University of Arizona's Lunar and Planetary Laboratory (LPL) have determined that an unseen object with a mass somewhere between that of Earth and Mars could be lurking in the Kuiper Belt <https://www.space.com/16144-kuiper-belt-objects.html>, a region beyond Neptune filled with thousands of icy asteroids, comets and dwarf planets. In January 2016 <https://www.space.com/31670-planet-nine-solar-system-discovery.html>, a separate group of scientists predicted the existence of a Neptune-size planet orbiting the sun far, far beyond Pluto — about 25 times farther from the sun than Pluto is. This hypothetical planet was dubbed "Planet Nine," so if both predictions are correct, one of these putative objects could be the solar system's 10th planet.


Hubble "Traps" a Vermin Galaxy
 <https://www.nasa.gov/sites/default/files/thumbnails/image/potw1722a.jpg>
The NASA/ESA Hubble Space Telescope is famous for its jaw-dropping snapshots of the cosmos. At first glance this Picture of the Week appears to be quite the opposite, showing just a blur of jagged spikes, speckled noise, and weird, clashing colors — but once you know what you are looking at, images like this one are no less breathtaking. This shows a distant galaxy — visible as the smudge to the lower right — as it begins to align with and pass behind a star sitting nearer to us within the Milky Way. This is an event known as a transit. The star is called HD 107146, and it sits at the center of the frame. Its light has been blocked in this image to make its immediate surroundings and the faint galaxy visible — the position of the star is marked with a green circle. The concentric orange circle surrounding HD 107146 is a circumstellar disk — a disk of debris orbiting the star. In the case of HD 107146 we see the disk face-on. As this star very much resembles our sun, it is an interesting scientific target to study: its circumstellar disk could be analogous to the asteroids in our Solar System and the Kuiper belt. A detailed study of this system is possible because of the much more distant galaxy — nicknamed the “Vermin Galaxy” by some to reflect their annoyance at its presence — as the star passes in front of it. The unusual pairing was first observed in 2004 by Hubble’s Advanced Camera for Surveys, and again in 2011 by Hubble’s Space Telescope Imaging Spectrograph. The latter image is shown here, as the Vermin Galaxy began its transit behind HD 107146. The galaxy will not be fully obscured until around 2020, but interesting science can be done even while the galaxy is only partly obscured. Light from the galaxy will pass through the star’s debris disks before reaching our telescopes, allowing us to study the properties of the light and how it changes, and thus infer the characteristics of the disk itself.

'Fireworks' Images from Hubble Telescope Capture Stars Forming Just After the Big Bang

A natural magnifying glass has sharpened images captured by NASA's Hubble Space Telescope <https://www.space.com/15892-hubble-space-telescope.html>, revealing a distant galaxy that contradicts existing theories about early star formation. By pairing Hubble with a massive galaxy cluster, scientists captured images 10 times sharper than the space telescope could snap on its own. The resulting images reveal star-forming knots of newborn stars only 200 to 300 light-years across, in a galaxy that formed only 2.7 billion years after the Big Bang. Previous theories suggested that star-forming regions in the early universe were much larger — at least 3,000 light-years across. [Hubble Space Telescope's Latest Cosmic Views <https://www.space.com/15235-hubble-space-telescope-latest-photos.html>] "There are star-forming knots as far down in size as we can see," Traci Johnson, a doctoral student in astronomy at the University of Michigan, said in a statement <https://www.nasa.gov/feature/goddard/2017/hubble-sees-clumps-of-new-stars-in-distant-galaxy>. Johnson is the lead author on two of the three research papers describing Hubble's new results, which were published July 6 in the The Astrophysical Journal <http://iopscience.iop.org/article/10.3847/1538-4357/aa7756> and the The Astrophysical Journal Letters.
