Animation of Rosetta’s trajectory over the last two months of its mission at Comet 67P/Churyumov–Gerasimenko.
The animation begins in early August, when the spacecraft started flying elliptical orbits that brought it progressively closer to the comet at its closest approach.
On 24 September 2016, Rosetta will leave its current close, flyover orbits and transfer into the start of a 16 x 23 km orbit that will be used to prepare and line up for the final descent.
On the evening of 29 September (20:50 GMT) Rosetta will manoeuvre onto a collision course with the comet, beginning the descent from an altitude of 19 km. The spacecraft will fall freely, without further manoeuvres, collecting scientific data during the descent.
The trajectory shown here was created from real data provided over the last month, but may not necessarily follow the exact comet distance because of natural deviations from the comet’s gravity and outgassing.

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy.
The first intermediate data release, containing among other things three-dimensional positions and two-dimensional motions of a subset of two million stars, demonstrates that Gaia’s measurements are as precise as planned, paving the way to create the full map of one billion stars to be released towards the end of 2017.
Located on the UK Space Gateway, Harwell Campus, the ESA-RAL Advanced Manufacturing Laboratory provides expertise and test services to investigate and optimise advanced materials and manufacturing processes in support of cutting-edge research and development. The facility is physically located within the Science and Technology Facilities Council’s Rutherford Appleton Laboratory (RAL).
The laboratory takes in samples of material destined for future space projects and puts them through various tests. A wide range of material properties and characteristics can be investigated in order to provide recommendations on how the materials can best be applied or improved before they can be considered for further development and used in a fully-fledged space mission. It has access to a metal-based 3D printer and is equipped with a suite of powerful microscopes, an X-ray CT machine and a range of furnaces.
Mechanical testing such as tensile and micro hardness testing is also performed.The lab is a gateway to accessing some of the extensive on-site testing facilities based on Harwell Campus, such as STFC’s ISIS Neutron Source, the Diamond Light Source synchrotron and the UK’s Central Laser Facility.

Currently around 63% of students are disengaged at school, meaning that they withdrawal either physically or mentally before they have mastered the skills that are required to flourish in later life. In this talk Scott Bolland explores the science of learning, the mismatch between how we teach and how the brain natural learns, and the important role that artificial intelligence could take in addressing the limitations in our current education system.
Dr Scott Bolland is the founder of New Dawn Technologies, a high-tech software company aiming to revolutionise education through the use of artificial intelligence. He has spent the last 20 years actively researching and teaching in the field of cognitive science – the scientific study of how the mind works – which spans disciplines such as psychology, philosophy, neuroscience, artificial intelligence and computer science. He holds a PhD in this field, as well as a university medal for outstanding academic scholarship.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Marissa Giustina’s research: http://arxiv.org/abs/1511.03190
Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since “accelerated” to faster than the speed of light. You might go further and say that there are more distant galaxies that we can’t see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn’t from doppler and this “acceleration” of the expanding universe isn’t actually causing a true increase in velocity.
Sometimes astronomers do say there is a faster than light “recession speed” by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that’s misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

On 14 March at 09:31 GMT ExoMars 2016 will be launched from Baikonur onboard a Proton rocket.
The joint European and Russian ExoMars mission will test key exploration technologies and search for evidence of methane and other rare gases in the Martian atmosphere. These gases could result from geological processes or they could be signatures of current biological activity on the planet.
This film examines the two European science instruments on the ExoMars Trace Gas Orbiter (TGO) – CaSSIS and NOMAD. The high-resolution CaSSIS (Colour and Stereo Surface Imaging System) acts as the orbiter’s scientific eye. It is a telescope with a sophisticated detector that can provide colour and stereo images over a nine and a half kilometre wide strip. CaSSIS will examine recurring slope linea – dark lines on the surface of Mars at different times of the day over the planet’s seasons. These linea are believed to be associated with liquid brine. They increase in size during the Martian spring and summer and fade away during autumn and winter.
NOMAD (Nadir and Occultation for MArs Discovery) will be the first high resolution instrument of its kind around the planet. It will observe information about Mars’ atmosphere by looking at the Sun during sunsets and sunrises. It contains three spectrometers – two working in the infrared and one in ultraviolet – and can identify trace gases in the atmosphere, such as methane. The presence of methane in Mars’ atmosphere could result from simple life forms like microbes.
The journey that the ExoMars 2016 spacecraft will take from Earth to Mars. ‘Distance to Mars’ is the straight-line distance between the spacecraft and Mars, and not the actual distance that the spacecraft will travel.
The mission is scheduled for launch in the 14–25 March window. The Trace Gas Orbiter and the Schiaparelli entry, descent and landing demonstrator module will separate on 16 October. Schiaparelli is set to enter the martian atmosphere on 19 October, while TGO will enter orbit around Mars.

A July 24 update at NASA headquarters, featured new surprising imagery and science results from the recent flyby of Pluto, by the New Horizons spacecraft. These included an image from the Long Range Reconnaissance Imager or (LORRI) – looking back at Pluto – hours after the historic flyby that revealed a haze in the planet’s sunlit atmosphere that extends as high as 80 miles above Pluto’s surface – much higher than expected. Models suggest that the hazes form when ultraviolet sunlight breaks apart methane gas. LORRI images also show evidence that exotic ices have flowed – and may still be flowing across Pluto’s surface, similar to glacial movement on Earth. This unpredicted sign of present-day geologic activity was detected in Sputnik Planum – an area in the western part of Pluto’s heart-shaped Tombaugh Regio. Additionally, new compositional data from New Horizons’ Ralph instrument indicate that the center of Sputnik Planum is rich in nitrogen, carbon monoxide, and methane ices. Also, Kepler discovers Earth’s “bigger cousin”, New crew launches to space station, EPIC view of Earth, Newman continues NASA center visits and Small Class Vehicle launch pad complete!

ESA astronaut Samantha Cristoforetti, from Italy, will shortly be ending her long-duration stay onboard the International Space Station. Launched in November 2014, the Futura mission is the result of a special agreement between NASA and the Italian Space Agency ASI.
During her time in orbit Samantha Cristoforetti has undergone an intensive programme of scientific research, educational and maintenance activities, as well as overseeing the undocking of ESA’s fifth – and last – Automated Transfer Vehicle.
ESA astronaut Samantha Cristoforetti running experiments in weightlessness during her Futura mission for scientists from all over the world. The International Space Station offers three state-of-the-art laboratories where research can be done without gravity. The European Columbus laboratory, the Japanese Kibo and the American Destiny module offer facilities for physics, biology, geophysics and medicine.
Samantha’s 40-hour work week is devoted to science and maintaining the weightless research centre. This video gives a fast-track impression of some of the experiments she worked on. In quick succession we see Samantha working on: exercise machine ARED, measuring her body mass, the robotic droids SPHERES, ESA’s microgravity glovebox, muscle-measurement machine MARES, centrifuge-incubator Kubik, Biolab, Materials Science Laboratory and ejecting miniature satellites called Cubesats into space.

It might have happened to you… You put a bottle of soda in the freezer for a few minutes just to get it ice cold. When you take the soda out of the freezer, it’s still a liquid (nothing unusual has happened just yet). However, the second you twist off the cap, the soda instantly freezes! The process is amazing to watch… but it’s a real bummer if you were thirsty (because it’s tough to suck ice out of the bottle). This is a great illustration of how carbon dioxide can lower the freezing point of water. Get some ice, some salt, and some plastic bottles of soda water and try this very cool science demo.
