Tiny satellites, also known as CubeSats, are pictured after being deployed into Earth orbit from a small satellite orbital deployer on the outside of the International Space Station’s Kibo laboratory module. The CubeSats were delivered aboard the Northrop Grumman Cygnus space freighter and will serve a variety of educational and research purposes for public and private organizations around the world.

The two new Galileo satellites launched in April have entered service, completing the second of three constellation planes. With every addition to the constellation, the precision, availability and robustness of the Galileo signal is improved. The next launch is planned in the coming weeks and the remaining six Galileo First Generation satellites will join the constellation in the next years.

The third Copernicus Sentinel-2 satellite launched today aboard the final Vega rocket from Europe’s Spaceport in French Guiana. Sentinel-2C will continue providing high-resolution data that is essential to Copernicus – Europe’s world leading Earth observation programme.
Sentinel-2C launched into orbit on 5 September at 03:50 CEST (4 September 22:50 local time) and separated from the Vega rocket at approximately 04:48 CEST.

Hubble Zooms into the Rosy Tendrils of Andromeda
NASA, ESA, M. Boyer (Space Telescope Science Institute), and J. Dalcanton (University of Washington); Image Processing: Gladys Kober (NASA/Catholic University of America) Clusters of stars set the interstellar medium ablaze in the Andromeda Galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way’s closest major galaxy. It measures approximately 152,000 light-years across and, with almost the same mass as our home galaxy, is headed for a collision with the Milky Way in 2-4 billion years. In the meantime, Andromeda remains an object of study for many astronomers.
As a spiral galaxy, Andromeda’s winding arms are one of its most remarkable features. NASA’s Hubble Space Telescope zoomed in to get a close look at one of its tendrils in the northeast, revealing swathes of ionized gas. These regions — which are common in spiral and irregular galaxies — often indicate the presence of recent star formation. The combination of stellar nurseries and supernovae create a dynamic environment that excites the surrounding hydrogen gas, flourishing it into a garden of star-studded roses.
NASA, ESA, M. Boyer (Space Telescope Science Institute), and J. Dalcanton (University of Washington); Image Processing: Gladys Kober (NASA/Catholic University of America) Scientists probed Andromeda’s spiral arms using Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) to analyze the collection of stars buried in its cosmic bouquets. With ACS and WFC3’s wide spectral coverage, Hubble could peer through the hedges of gas and observe a valuable sample of these stars. The extent of the study spanned a vast range of stars, providing not just a clear view of Andromeda’s stellar history and diversity, but also more insight on stellar formation and evolution overall. By examining these stars in our local cosmic neighborhood, scientists can better understand those within galaxies in the distant universe.
