  • Proba-3: Dancing with the stars

    Proba-3: Dancing with the stars

    Dancing is probably the oldest human artform – and now ESA’s Proba-3 precision formation-flying mission intends to extend the art of dance to space.

    Like dancers, a pair of minisatellites will move around each other, their relative positions maintained to millimetre-scale precision, as if they were both parts of one giant spacecraft.

    Their mission is to cast a shadow from one minisatellite onto another, in order to form an artificial total solar eclipse in space – then study the fine details of the Sun’s wispy atmosphere, the solar corona.

    Franco Ongaro, ESA Director of Technical and Quality Management; Frederic Teston, Head of System and Cost Engineering; Andrea Santovincenzo, ESA engineer and the project’s manager Agnes Mestreau-Garreau, explain how to go about teaching a space mission to dance.

    The State of NASA on This Week @NASA

    NASA Administrator Charles Bolden, speaking during his Feb. 2 “State of NASA” address at Kennedy Space Center in Florida after the release of President Obama’s Fiscal Year 2016 $18.5 billion budget proposal for NASA said, “I can unequivocally say that the State of NASA is strong.” The proposed budget is a half-billion-dollar increase over last year’s enacted budget, which, the Administrator noted, “is a clear vote of confidence to you – the employees of NASA and the ambitious exploration program you are executing.” The budget facilitates NASA’s plan moving forward, which includes development of new vehicles and technologies needed for unprecedented human missions to an asteroid and to Mars, commercial partnerships to provide transportation to and from the International Space Station from the United States and research on the station for the benefit of future deep space travelers and people living on our home planet. Also, New views of Pluto, Soil moisture mission underway and Virginia Aerospace Day!

  • ESA Euronews: The dark side

    ESA Euronews: The dark side

    All we can see around us, from planet Earth to distant galaxies, represents just five per cent of the Universe – the rest is dark energy or dark matter. So what do we know and what do we not know about these elusive components of the cosmos?

    The simple answer is that we don’t know much about dark matter and even less about dark energy.

    However, that could change quite soon thanks to groundbreaking research being done by scientists at ESA and CERN, home to the world’s foremost particle accelerator, the Large Hadron Collider. The LHC’s discovery three years ago of the Higgs Boson set researchers on a voyage of discovery to the dark side of the Universe. They are about to fire up the colossal accelerator again this year, and for the first time at full power. That extra energy is what’s giving optimism for new revelations about dark energy and dark matter. One scientists tells Space: “we might have a discovery even in the first days, if not in the first weeks.”

    At the same time ESA is building a new space telescope called Euclid which will watch how the gravity of dark matter acts on galaxies, and how dark energy is pushing the expansion of our Universe.

    Find out how science is unraveling the dark mysteries of the cosmos.

  • Journey to the surface of a comet

    Journey to the surface of a comet

    Rosetta’s deployment of Philae to land on Comet 67P/Churyumov–Gerasimenko.

    The animation begins with Philae still on Rosetta, which will come to within about 22.5 km of the centre of the nucleus to release the lander on 12 November 2014.

    The animation then shows Philae being ejected by Rosetta and deploying its own three legs, and follows the lander’s descent until it reaches the target site on the comet about seven hours later.

    The animation is speeded up, but the comet rotation is true: in the time it takes for Philae to descend, the nucleus has rotated by more than 180º (the comet’s rotation period is 12.4 hours).

    The final steps of Philae’s descent towards the comet are shown as seen by a hypothetical observer close to the landing site on the comet.

    Acknowledgement: The background image of the sequence showing Philae closing in on the landing site was taken by Rosetta’s OSIRIS narrow-angle camera (ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA) on 14 September 2014 from a distance of about 30 km.

  • Rosetta puts on the brakes

    Rosetta puts on the brakes

    Rosetta is about to put on the brakes to ensure that it is on target for comet 67P/Churyumov-Gerasimenko.

    This video explains the crucial orbit correction manoeuvres that are required to slow down Rosetta’s speed, relative to the comet, from 750 metres per second to just one metre per second between 21 May and 5 August. By then, nine thruster burns (including one test burn in early May) will have reduced the distance between them from one million kms to just under 200 kms.

    We also see the first images of the comet from the spacecraft’s OSIRIS camera (Optical, Spectroscopic and Infrared Remote Imaging System), taken between 24 March and 4 May 2014. As the spacecraft gets closer to the comet, further images will improve the orbital corrections and provide more details about the comet’s shape, size and rotation.

    MIRO, built by an international team for the European Space Agency, will start taking measurements from late May onwards and will measure gases released from the comet as it approaches the Sun.

    To mark the occasion, the team produced a fly-through movie of the ancient flood plain Kasei Valles. The movie is based on the 67-image mosaic released as part of the ten-years-since-launch celebrations in June 2013. See http://www.esa.int/Our_Activities/Space_Science/Mars_Express/The_floodwaters_of_Mars.

    The scene spans 987 km in the north–south direction, 19–36°N, and 1550 km in the east–west direction (280–310°E). It covers 1.55 million square kilometres, an area equivalent to the size of Mongolia.

    Kasei Valles is one of the largest outflow channel systems on Mars, created during dramatic flood events. From source to sink, it extends some 3000 km and descends 3 km.

    Kasei Valles splits into two main branches that hug a broad island of fractured terrain — Sacra Mensa — rising 2 km above the channels that swerve around it. While weaker materials succumbed to the erosive power of the fast-flowing water, this hardier outcrop has stood the test of time.

    Slightly further downstream, the flood waters did their best to erase the 100 km-wide Sharonov crater, crumpling its walls to the south. Around Sharonov many small streamlined islands form teardrop shapes rising from the riverbed as water swept around these natural obstacles.

    The Planetary Science and Remote Sensing Group at Freie Universität Berlin produced the movie. The processing of the High Resolution Stereo Camera image data was carried out at the DLR German Aerospace Center.

  • Rosetta — the story so far

    Rosetta — the story so far

    This short movie tells the story of Rosetta’s journey through the Solar System so far, through the voices of some of the many people involved in this exciting mission. ESA’s Rosetta spacecraft launched in March 2004 and has since been chasing down comet 67P/Churyumov-Gerasimenko, where it will become the first space mission to orbit a comet, the first to attempt a landing on a comet’s surface, and the first to follow a comet as it swings around the Sun. In the last ten years Rosetta has made 3 flybys of Earth and 1 of Mars, and passed by and imaged asteroids Steins and Lutetia. Operating on solar energy alone, in June 2011 Rosetta was placed into deep space hibernation as it cruised nearly 800 million kilometres from the warmth of the Sun, close to the orbit of Jupiter. On 20 January, Rosetta will wake up at 673 million kilometres from the Sun and about 9 million km from the comet, ready for the next leg of its epic adventure.

  • Rosetta’s orbit around the comet

    Rosetta’s orbit around the comet

    After a ten year journey through space, ESA’s Rosetta spacecraft will reach comet 67P/Churyumov-Gerasimenko in August 2014. After catching up with the comet Rosetta will slightly overtake and enter orbit from the ‘front’ of the comet as both the spacecraft and 67P/CG move along their orbits around the Sun. Rosetta will carry out a complex series of manoeuvres to reduce the separation between the spacecraft and comet from around 100 km to 25-30 km. From this close orbit, detailed mapping will allow scientists to determine the landing site for the mission’s Philae lander. Immediately prior to the deployment of Philae in November, Rosetta will come to within just 2.5 km of the comet’s nucleus.
    This animation is not to scale; Rosetta’s solar arrays span 32 m, and the comet is approximately 4 km wide.

  • Mars 360: the north pole

    Mars 360: the north pole

    Enjoy views of the martian north pole from all angles in this new animation from ESA’s Mars Express.

    The ice cap has a diameter of about 1000 km and consists of many thin layers of ice mixed with dust that extend to a depth of around 2 km below the cap. The prominent gap in the ice cap is a 318 km-long, 2 km-deep chasm called Chasma Boreale.

    The layers result from variations in the orbit and rotation of Mars that affect the amount of sunlight received at the poles, and thus the amount of melting and deposition of materials over time. Meanwhile, strong prevailing winds are thought to be responsible for shaping the spiral troughs.

    The polar ice cap in this movie was constructed using data provided by the Mars Advanced Radar for Subsurface and Ionospheric Sounding instrument, MARSIS.

    Low-frequency radio waves beamed towards the surface are reflected back to Mars Express from the planet’s surface and from interfaces between layers of different materials underground.

    The strength and timing of the radar echoes are a gauge of the depths of different types of interfaces, such as between rock, water or ice. This information can then be translated into 3D views, as seen in this movie.

    ISON vs the Sun

    The ESA/NASA SOHO satellite watched as Comet ISON made its closest approach to the Sun on 28 November, at a distance of around 1.2 million kilometres from the Sun’s visible surface. Did it survive? Early reports suggested that only the comet’s tail continued to follow along ISON’s orbit. Further observations will reveal if a chunk of the comet’s nucleus survived.

    ESA Euronews: The real-life space cadets: Abbie, Marc and Maria

    Meet the space cadets, three young engineers with enviable jobs that are quite literally out of this world. This edition of Space focuses on three professionals who’ve turned their dreams of working in space into real down-to- Earth careers.

    In the UK, 26-year-old Abbie Hutty, a spacecraft structures engineer at Astrium, is a proud member of the ExoMars team. She is developing the structure of the mission’s rover, ensuring that the actual body of the vehicle and other components are all structurally strong enough to withstand the launch from Earth, and landing on Mars.

    Twenty-seven-year-old Marc Costa Sitjà, Science Operations Engineer at the European Space Agency, uses the huge antenna at Cebreros, west of Madrid, to ‘drive’ ESA’s Venus Express spacecraft around the planet. Every day he sends commands and receives data to and from the spacecraft from the agency’s ESAC facility near the Spanish capital.

    Maria Komu, a 27-year-old researcher at the Finnish Meteorological Institute, works on Finnish mini satellite Aalto-1, and has a hands-on role developing a weather instrument for ESA’s ExoMars EDM mission.

    Space is a childhood dream turned reality for all three. For Abbie the realisation that space wasn’t just science fiction came when she was still at school and she heard of the Beagle 2 mission to Mars, a lander that was developed in the UK by British engineers. Maria tells the story of a book about a school visit around the solar system that enchanted her as a young girl. Meanwhile Marc cites a vivid blue image of Venus as an inspiration to his career.

    Abbie, Marc and Maria are all educated to masters level, while Maria continues studying towards a doctorate. They’re on the first steps of the career ladder, and that means plenty of learning ‘on-the-job’. Maria had to master soldering, programming, and testing, Marc developed his skills by creating software that helped a mission to better fulfill its purpose, while Abbie had to understand better the behaviour of particular materials in the cold vacuum of space.

    The excitement of working in space is summed up by Abbie: “I think the space industry is quite a privileged industry to work in, because whilst you are still managing projects and meeting schedules and deadlines, and creating a product, at the end of the day that requires a certain amount of processes down on it, you can also come down to the clean rooms and look through the window and see your part of a spaceship, and think ‘that’s going to Mars, and I did that bit’, and you don’t get that anywhere else.”
