And liftoff! A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station carrying the Dragon resupply spacecraft on the sixth commercial resupply services mission to @ISS. Liftoff was at 4:10 p.m. EDT, Tuesday, April 14. Research that will help prepare our astronauts and robotic explorers for future missions to Mars is among the two tons of cargo on its way to the International Space Station aboard Dragon. Dragon's cargo will support approximately 40 of the more than 250 science and research investigations that will be performed during Expeditions 43 and 44, including numerous human research investigations for NASA astronaut Scott Kelly's one-year mission in space.

It's launch day for our International Space Station (@ISS) cargo resupply flight. The weather forecast continue to predict a 60 percent of favorable conditions for today's launch. Liftoff of the SpaceX Falcon 9 rocket and Dragon spacecraft is targeted for 4:33 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. The Dragon spacecraft will be filled with more than 4,300 pounds of supplies and payloads, including critical materials to directly support about 40 of the more than 250 science and research investigations that will occur during Expeditions 43 and 44. Science payloads will study new ways to possibly counteract the microgravity-induced cell damage seen during spaceflight, the effects of microgravity on the most common cells in bones, gather new insight that could lead to treatments for osteoporosis and muscle wasting conditions, continue studies into astronaut vision changes and test a new material that could one day be used as a synthetic muscle for robotics explorers of the future. Also making the trip will be a new espresso machine for space station crews. After five weeks at the space station, the spacecraft will return with more than 3,000 pounds of cargo, including crew supplies, hardware and computer resources, science experiments, space station hardware, and trash.

Many of Hubble's most iconic images reveal majestic nebulae in the nearby universe. These observations advance our understanding of how gas and dust come together to form nebulae, and how these nebulae become the sites for newborn star and planetary systems. Ken Carpenter, Hubble Operations Project Scientist, talks about his favorite Hubble image of the Carina Nebula. #Hubble25; -
From supermassive black holes at galactic centers to giant bursts of star formation to titanic collisions between galaxies, Hubble Space Telescope discoveries allow astronomers to probe the current properties of galaxies as well as examine how they formed and developed. Jennifer Wiseman, Senior Project Scientist for the Hubble Space Telescope, talks about her favorite Hubble image of the NGC 1309 spiral galaxy. #Hubble25; -
The keen eye of the Hubble Space Telescope has revealed intricate details of the shapes, structures and histories of galaxies — whether alone, as part of small groups or within vast clusters. Jane Rigby, Astrophysicist at Goddard Space Flight Center, talks about her favorite Hubble image, galaxy cluster RCS2 032727-132623. #Hubble25;

The Hubble Space Telescope has a major impact in every realm of astronomy, from the solar system to the edge of the universe. Andrea Razzaghi, NASA HQ Astrophysics division deputy director, on why Hubble’s images are important. #Hubble25; -
One of the Hubble Space Telescope’s greatest triumphs has been the clear view it has given of very distant galaxies. Is going to space worth the trouble? Paul Hertz, NASA HQ Astrophysics division director, talks about how Hubble completely changed his mind. #Hubble25; -
Over the last 25 years, Hubble has revealed properties of space and time that for most of human history were only probed in the imaginations of scientists and philosophers alike. Today, Hubble continues to provide views of cosmic wonders never before seen and is at the forefront of many new discoveries. Mike Garcia, NASA Headquarters Hubble Project Scientist, talks about the significance of Hubble. #Hubble25; -
Since launching in 1990, Hubble has far exceeded its original science goals and unveiled an even more complex and mysterious universe than once envisioned. It has inspired the world and sparked humanity’s natural curiosity. “We are the Hubble generation, and our world is bigger than our planet.” Debra Wallace, NASA HQ Deputy Project Scientist. #Hubble25; -
The Hubble Space Telescope is one of the most powerful scientific instruments ever conceived. Hubble’s most important discoveries have provided answers to questions that astronomers did not yet know how to ask, and found objects that were not yet imagined. Kate Whitaker, NASA Postdoctoral Program Fellow, talks about one of Hubble’s greatest achievements. #Hubble25;

Since launching 25 years ago this month, Hubble has reinvigorated and reshaped our perception of the cosmos and uncovered a universe where almost anything seems possible within the laws of physics. Amber Straughn, Astrophysicist at Goddard Space Flight Center, talks about her favorite Hubble image. #Hubble25; -
Hubble celebrates its 25th Anniversary on April 24! Dr. John Grunsfeld, Astronaut and Assistant Administrator of NASA’s Science Mission Directorate, speaks on Hubble’s success, thanks to teamwork. #Hubble25; -
Happy Birthday Hubble! This weekend, we’re celebrating some of the stories behind 25 years of the Hubble Space Telescope. The telescope is credited with discovering many distant galaxies, confirming the existence of supermassive black holes in galactic centers, and discovering birthplaces of stars, relaying images almost too mind-boggling to comprehend. NASA Administrator Charlie Bolden piloted the space shuttle Discovery that brought Hubble into orbit 25 years ago. #Hubble25; -
Stares into the Crammed Center of Star Cluster: This image shows the center of the globular cluster Messier 22, also known as M22, as observed by the Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 billion years old. Messier 22 is one of about 150 globular clusters in the Milky Way and at just 10,000 light-years away it is also one of the closest to Earth. It was discovered in 1665 by Abraham Ihle, making it one of the first globulars ever to be discovered. This is not so surprising as it is one of the brightest globular clusters visible from the northern hemisphere, located in the constellation of Sagittarius, close to the Galactic Bulge — the dense mass of stars at the center of the Milky Way.

Our Sun Came Late to the Milky Way's Star-Birth Party: Artist's view of night sky from a hypothetical planet within a young Milky Way-like galaxy 10 billion years ago, the sky are ablaze with star birth. Pink clouds of gas harbor newborn stars, and bluish-white, young star clusters litter the landscape. In one of the most comprehensive multi-observatory galaxy surveys yet, astronomers find that galaxies like our Milky Way underwent a stellar "baby boom," churning out stars at a prodigious rate, about 30 times faster than today. Our sun, however, is a late "boomer." The Milky Way's star-birthing frenzy peaked 10 billion years ago, but our sun was late for the party, not forming until roughly 5 billion years ago. By that time the star formation rate in our galaxy had plunged to a trickle. Image Credit: NASA/ESA/Z. Levay (STScI) (artist pic) #nasa #milkyway #space #esa #galaxy #hubble #sun #hubble25 #science;
