Vũ Phá1,285 STOP!! Before you share this circle please read everything detailed below:This is the newest release of my #topengagers  circle.  This week I wanted to give this circle a SERIOUS overhaul. So I deleted it. Then, I started with the adding back the core G+'ers of this circle (if you don't know who they are start engaging more!!) and I then added in those who shared the circle previously and whose posts were high quality.  I am sure some have slipped through the cracks, so if that is you please do not be offended, but be certain to get in touch with me. This circle is the result of the overhaul.  Add this circle only if you are interested in great content, great engagers and helping make G+ a better, more social place.  To Be Included Next Time1. Make sure your posts are quality2. Be a great G+ member3.

Bobo Fett0Those of you flocking here from the horror that is Facebook, or any that have been here for a while, or maybe even never a part of FB, some pointers to get you started.First thing to know if you type a question mark pretty much anywhere (as long as you don't have a text field in focus, in other words a blinking cursor where you would type text) in G+ you get a little pop up that gives you some handy basic keyboard shortcuts.If you are new here and and you are looking to make your feed more active, click the two little circles labeled Find people in the icons down the left side of the G+ page.  There you can search for people you know and add them to your circles.  Circles are what G+ uses to allow you to organize your friends list.  G+ starts you off with a few default Circles to use, you just need to add people and/or pages to things you enjoy to one of those circles.  Once you have you will see grey buttons at the top of your main feed (The page you get to if you click the big Google+ icon in the top left hand corner).  The first button is the default All circles button, here you will see all of the posts of every person/page you have added to any of your circles.  Next to the All button you will see buttons with the names of your circles.  If you click one of them you will of course see just posts from people/pages in that circle, but also on the rightish side, not quite at the top of the page, you will find a button that says Settings.  That is a drop down that gives you two check boxes.  One is "Show posts in home stream" the other is "Get Notified of new posts".  They pretty much do what they say, and "get notified" means any posts from this circle will make the number between your name and the + Share button in the top right hand corner increment and go red.  You can click that number at any time (even if it's red and 0) to get a drop down window which will show a condensed version of all posts from circles you get notified about. It will also notify you any time someone circles you back, and any +1s you have received in posts or comments you have made. As well as, comments in posts you have also commented on. On this Settings button you will also see a grey area that says Amount.  If you hover over that you get to choose More, Standard, or Fewer.  Which controls how frequently the posts from that circle appear in your feed.If you combine the above tools with the fact that you can change the name of any circle, add as many as you like, and also have people in more than one circle, you have very granular control over what posts you see and when, and exactly who can see your posts.  You can also share your circles with other people, as I have done below.  If you click the View shared circle button below, you will be able to see all the pages in a circle I call, go figure, Pages.  You can look through it and if you like everything you can just add the whole circle as a new circle.  Or, you can pick and choose which things you find interesting and add just them to your own circle that you already have or create a new circle.  Moving stuff from circle to circle is as easy and dragging the rectangle for that particular page/person and dropping onto the circle you want it to be in.  You could also just add this circle in full and then just delete the stuff you don't want (little x in top right hand corner of each rectangle when you hover over it).  Or just view this circle to get ideas for what sort of stuff can be searched for, and use the search box at the top of the Find people/Circle page to find stuff you like.Now once you have some friends added to circles, and pages/people you would like to follow added as well, your feed will get much more interesting. Now on to posting your own stuff.  In the Share what's new... field at the top of pages, you can of course type anything you like2013-05-03 19:55:12143001CC G+

NASA astronauts Steve Swanson and Rick Mastracchio completed a short spacewalk from the International Space Station this morning to replace a failed Multiplexer/Demultiplexer back up computer.

The backup computer failed April 11 after a routine health check by the Mission Control team in Houston. While the primary computer continues operating flawlessly NASA managers ordered Wednesday’s spacewalk repair to ensure redundancy on critical systems. The computer outage did not pose a risk to the six crew members aboard the space station.

While out for the spacewalk, Mastracchio snapped this image of the SpaceX Dragon cargo spacecraft attached to the ISS and shared it on Twitter following the conclusion of today's spacewalk.

Our radar imaging mission got underway in early April to collect data over targets in the Gulf Coast area of the southeastern United States. Our C-20A aircraft, a modified Gulfstream III, is carrying the Uninhabited Aerial Vehicle Synthetic Aperture Radar instrument in a specialized pod. Research during the deployment is covering a variety of topics, including volcanoes, glaciers, forest structure, levees, and subsidence. It is also providing vegetation data sets for satellite algorithm development. The volcanoes of Central and South America are of interest because of the hazard they pose to nearby population centers. A majority of the research will focus on gathering volcano deformation measurements. Surface deformation often precedes other signs of renewed volcanic activity.

Today, April 22, 2014 is Earth Day, and what better way to celebrate than taking a look at our home planet from space.

NOAA's GOES-East satellite captured this stunning view of the Americas on Earth Day, April 22, 2014 at 11:45 UTC/7:45 a.m. EDT. The data from GOES-East was made into an image by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.

GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.

In today's blog post from NASA Administrator Bolden, he likens the path to Mars to NASA's journey to the moon. 

"It is important to remember that NASA sent humans to the moon by setting a goal that seemed beyond our reach. In that same spirit, we have made a human mission to Mars the centerpiece of our next big leap into the unknown."

SpaceX Dragon Caputered by Robotic Arm! On Sunday, April 20, the Expedition 39 crew aboard the International Space Station welcomed nearly two-and-a-half tons of supplies and scientific payloads to the station with the arrival of the third SpaceX Dragon commercial cargo spacecraft. This image of SpaceX Dragon grappled by Canadarm2 was sent down by Flight Engineer Steve Swanson to Instagram with the message, "We have a Dragon. All is good."

With Dragon securely in the grasp of Canadarm2, the robotics officer at Mission Control remotely operated the arm to install the capsule to its port on the Earth-facing side of the Harmony module. Once Dragon was in place, Flight Engineer Rick Mastracchio monitored the Common Berthing Mechanism operations for first and second stage capture of the cargo ship, assuring that the vehicle was securely attached to the station with a hard mate.

As seen on #Cosmos: Meteors

Shooting stars, or meteors, are bits of interplanetary material falling through Earth's atmosphere and heated to incandescence by friction. These objects are called meteoroids as they are hurtling through space, becoming meteors for the few seconds they streak across the sky and create glowing trails.

Scientists estimate that 44 tonnes (44,000 kilograms, about 48.5 tons) of meteoritic material falls on the Earth each day. Several meteors per hour can usually be seen on any given night. Sometimes the number increases dramatically - these events are termed meteor showers. Some occur annually or at regular intervals as the Earth passes through the trail of dusty debris left by a comet. Meteor showers are usually named after a star or constellation that is close to where the meteors appear in the sky. Perhaps the most famous are the Perseids, which peak... more »

Researchers were greatly surprised to discover 3-million-year-old landscape beneath Greenland Ice Sheet! The finding provides strong evidence that the Greenland Ice Sheet has persisted much longer than previously known, enduring through many past periods of global warming.

The new discovery indicates that even during the warmest periods since the ice sheet formed, the center of Greenland remained stable. "It’s likely that it did not fully melt at any time," said University of Vermont geologist and lead author Paul Bierman. This allowed a tundra landscape to be locked away, unmodified, under ice through millions of years of global warming and cooling.

The Grand Canyon in northern Arizona is a favorite for astronauts shooting photos from the International Space Station. The steep walls of the Colorado River canyon and its many side canyons make an intricate landscape that contrasts with the dark green, forested plateau to the north and south.

The Colorado River has done all the erosional work of carving away cubic kilometers of rock in a geologically short period of time. Visible as a darker line snaking along the bottom of the canyon, the river lies at an altitude of 715 meters (2,345 feet), thousands of meters below the North and South Rims. Temperatures are furnace-like on the river banks in the summer.

Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling.

The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are somewhat far from their stars. And with some water remaining liquid on the surface long-term, such planets could maintain favorable conditions for life. Fore more information, visit: http://go.nasa.gov/1nquyFz

Eclipse! From open prairie land on the 1625-acre Johnson Space Center site, one of our photographers took this multi-frame composite image of the so-called "Blood Moon" lunar eclipse in the early hours of April 15. During these rare events, the full moon rapidly darkens and then glows red as it enters the Earth's shadow. Though a lunar eclipse can be seen only at night, it's worth staying up to catch the show. The next full lunar eclipse visible in the U.S. will be in 2019.

The International Space Station Program and SpaceX have selected Friday, April 18 for the next launch attempt for the Falcon 9 rocket to send the Dragon cargo craft on the company’s third commercial resupply mission to the space station. Launch is scheduled for 3:25 p.m. EDT. NASA TV coverage will begin at 2:15 p.m. 

A launch on Friday results in a rendezvous with the space station on Sunday, April 20 and a grapple at 7:14 a.m. NASA TV coverage will begin at 5:45 a.m. with berthing coverage beginning at 9:30 a.m.

SpaceX has settled on a backup launch date of Saturday, April 19 for the best pair of launch dates for the science payloads being delivered to the station. If needed, a Saturday launch would occur at 3:02 p.m. NASA TV coverage would begin at 2 p.m. This would be a three-day transit to the station instead of two days with grapple on Tuesday, April 22.

Space station astronauts focused today on preparations for a contingency spacewalk to be conducted in the next week or so. Meanwhile station program managers and SpaceX officials are working toward scheduling dates for the next launch attempt for Dragon cargo spacecraft and that contingency spacewalk, while managing all this around the planned undocking and redocking of a Russian cargo craft next week. Monday's launch attempt of the SpaceX Dragon cargo craft, loaded with nearly 5,000 pounds of supplies and experiment hardware, was scrubbed due to a helium leak on the Falcon 9 rocket's first stage. The next launch opportunity would be Friday at 3:25 p.m. EDT if the issue can be resolved.

Eclipse! The United States was in a prime orbital position and time of day to view the eclipse on April 15. Depending on local weather conditions, the public got a spectacular view looking into the sky as the moon's appearance changed from bright orange to blood red to dark brown and perhaps gray. The eclipse is a phenomenon that occurs when the Earth, moon and sun are in perfect alignment, blanketing the moon in the Earth's shadow. The United States will not be able to witness a full lunar eclipse in its entirety again until 2019. This image was taken in San Jose, Calif.
