Docking gives Intelsat telecoms satellite new lease of life Image copyright Northrop Grumman Two American satellites have docked high over the Atlantic in a demonstration of what many commentators expect to be a burgeoning new industry. One of the platforms is an old telecoms spacecraft low on fuel; the other is an auxiliary unit that will now take over all the former's manoeuvring functions. This will allow Intelsat-901 to extend its 19-year mission of relaying TV and other services by another five years. The event has been described as a major accomplishment by the firms involved.

Stars align for epic space missions Image copyright ESA Two of the most exciting space missions of the 2030s are likely now to be launched within a year of each other. European Space Agency member states are poised to increase the organisation's science budget on Thursday by 10%. This would make it possible to align projects to build a big X-ray telescope and a trio of satellites to sense the collision of gargantuan black holes. It's important they fly together because the insights they'll bring are highly complementary.

Exploring Planets in the Classroom: Hands-on science activities Exploring Planets in the Classroom was a long-running summer workshop in Planetary Geosciences offered at the University of Hawai‘i at Manoa for the state's K-12 educators and librarians under the direction of Dr. G. Jeffrey Taylor. Hands-on activities in this course were developed and/or tested by the Hawai‘i Space Grant Consortium in cooperation with educators statewide. In 1996 the workshop transformed into this website to assist educators and resource specialists around the globe to find hands-on activities that match science standards in elementary, middle, high school, and college classrooms. ISS crew blast off after long quarantine Image copyright Getty Images Three new crew members have arrived at the International Space Station (ISS) after a launch carried out under tight restrictions due to the coronavirus. The Russian Soyuz rocket carrying cosmonauts Anatoly Ivanishin and Ivan Vagner and Nasa astronaut Chris Cassidy took off from Kazakhstan on Thursday. Pre-launch protocols were changed to prevent the virus being taken to the ISS. Only essential personnel were allowed at the launch site for the blast-off. Support workers wore masks and kept their distance as the crew walked to the bus to take them to the spacecraft.

i21 Interactive Classroom / Overview Making Technology Educational Part of the Integrated Technology Support Services Department, the Educational Technology (Ed Tech) team seeks to improve student achievement through seamless integration of the district's Common Core Curriculum with a suite of i21 technologies designed to create an engaging and personalized learning environment. The Integrated 21st Century (i21) Interactive Classroom The i21 classroom is an engaging and personalized learning environment designed to optimize teaching and learning through the interconnected use of mobile computing, audio, visual and formative assessment technologies across the curriculum. With this vision and funding through Propositions S and Z, San Diego Unified has taken a bold step toward transforming the learning environment in each of its 7,000 classrooms. Over five years (beginning in 2009), approximately 20 percent of classrooms per year will receive a suite of new technology tools.

Dancing gargantuan black holes perform on cue Media playback is unsupported on your device Astronomers have been able to test key consequences of Einstein's theories by studying the way a couple of black holes move around each other. One of these objects is a true colossus - a hole weighing 18 billion times the mass of our Sun; the other not quite so big at "only" 150 million Sun masses. Scientists managed to predict their interactions very precisely.

Pentagon releases UFO videos for the record Media playback is unsupported on your device The US Department of Defense has released three declassified videos of "unexplained aerial phenomena". The Pentagon said it wanted to "clear up any misconceptions by the public on whether or not the footage that has been circulating was real". The videos had already been leaked in 2007 and 2017.

James Webb Space Telescope comes together Image copyright NASA/Chris Gunn The successor to the Hubble observatory has reached a key milestone in its construction. All the elements that make up the James Webb Space Telescope (JWST) have been brought together for the first time. It sets the stage for some critical tests that will hopefully lead to a launch to orbit sometime in 2021. JWST will use a colossal mirror and state-of-the-art instruments to try to see the glow from the very first stars to shine in the Universe.

Milky Way galaxy is warped and twisted, not flat Image copyright OGLE/Warsaw UNiversity Our galaxy, the Milky Way, is "warped and twisted" and not flat as previously thought, new research shows. Analysis of the brightest stars in the galaxy shows that they do not lie on a flat plane as shown in academic texts and popular science books. Astronomers from Warsaw University speculate that it might have been bent out of shape by past interactions with nearby galaxies. The new three dimensional map has been published in the journal Science. Moon landings: What was the 1969 Apollo 11 mission? Image copyright Reuters It's nearly 50 years since the US became the first country to land men on the Moon. The Apollo 11 mission was a huge moment in US and world history, but what exactly happened and why does it matter? Why did the US want to go to the Moon? A space race developed between the US and the then Soviet Union, after the 1957 launch of the first Soviet Sputnik satellite.

The CubeSat revolution changing the way we see the world Image copyright Alamy There is a beloved story about the dimensions of the space shuttle. Apparently the booster rockets had to fit through railway tunnels designed to accommodate a horse and cart. In short, the space shuttle boosters were the width of two horses' backsides.
