Joint UK and Algeria CubeSat Mission: First colour image

 
  • Captured image marks an important milestone as AlSat Nano is Algeria’s first CubeSat mission.
  • Surrey Space Centre (SSC), University of Surrey was responsible for the design, build and verification of the spacecraft including a training program for Algerian students, as well as supporting development of a ground station in Algeria and training their operators.
  • AlSat Nano stuck to a tight development schedule, with less than 18 months between payload selection and flight readiness, allowing UK industry and academia to stay ahead of the curve in the competitive global CubeSat market.


  • AlSat Nano is a joint nanosatellite mission between the UK Space Agency and Algerian Space Agency (ASAL) as part of an on-going initiative to enhance collaboration. The UK Space Agency has funded the design, build and verification of the spacecraft at Surrey Space Centre (SSC), University of Surrey, as a hands-on learning exercise for Algerian postgrad students to demonstrate the practical elements of low cost space technology. ASAL has provided the launch, and operations are being undertaken in Algeria by ASAL operators trained at SSC.

    The image was taken by the Open University C3D2 instrument’s wide field camera on 3rd December 2016 over the Arkhangelsk Oblast region, on the North West coast of Russia. The image was captured under twilight conditions at dawn, showing the coastline to the top of the image, and a brief winter sunrise over the arctic region with a deep red-brown hue. Through the cloud cover there is evidence of hills and snow on mountains, and mist in the river valleys. The object in the foreground is the Oxford Space Systems Ltd AstroTubeTM Boom payload, also carried on board the spacecraft.

    Prof Guglielmo Aglietti, Director of Surrey Space Centre, said: “AlSat Nano has been an exciting project for the Surrey Space Centre to be leading. Educational and research elements, and the technology knowledge transfer with the Algerian Space Agency were key parts of this project. Additionally, the development of this nanosatellite platform has been a great opportunity to work with UK payload providers, who are demonstrating some exciting new technologies.”

    AlSat Nano is Algeria’s first CubeSat mission and is globally showcasing the capability of UK technology in partnership with industry and academia. With a spacecraft the size of a shoebox yet featuring all the core subsystems of much larger satellites, the programme demonstrates how CubeSats can be assembled quickly and launched at a fraction of the cost. This will help Algeria strengthen its domestic space technology capability by giving their scientists and engineers first-hand experience of spacecraft operations.

    Dr Abdewahab Chikouche, Director of Space Programmes at Algerian Space Agency, said: “The Alsat-1N project is a concrete example of the success of our cooperation with UKSA. This project, very enriching from the scientific and technological point of view, allowed ASAL engineers to progress in the integration and testing of nanosatellites and acquire autonomy in its operation. This project will enable Algerian researchers and academics to strengthen national capabilities in advanced space technology.”

    The AlSat Nano mission hosts and has demonstrated three payloads, showcasing innovative technologies from UK suppliers:  C3D2 imager from Open University, AstroTubeTM Boom from Oxford Space Systems and Thin Film Solar Cell from Swansea University.

    Dr Ben Taylor, the SSC AlSat-Nano Project Lead, said: “The Alsat-Nano mission has been a great opportunity to work with a diverse and committed team across the UK and Algeria. The spacecraft carries some exciting new technologies which are already returning some great results and we are looking forward to further results as the mission continues”.

    The mission builds on the success of the flight services division at Surrey Space Centre, who are involved with a range of on-going spacecraft missions including CubeSats and larger scale missions.  A major on-going project is RemoveDebris, a €15.2M mission led by Surrey, aiming to be one of the world’s first demonstrations of space junk removal when it launches later this year.

    Comet-Like Canes Venatici (The Hunting Dogs)

     
     



    The lesser-known constellation of Canes Venatici (The Hunting Dogs), is home to a variety of deep-sky objects — including this beautiful galaxy, known as NGC 4861. Astronomers are still debating on how to classify it. While its physical properties — such as mass, size and rotational velocity — indicate it to be a spiral galaxy, its appearance looks more like a comet with its dense, luminous “head” and dimmer “tail” trailing off. Features more fitting with a dwarf irregular galaxy.

    Although small and messy, galaxies like NGC 4861 provide astronomers with interesting opportunities for study. Small galaxies have lower gravitational potentials, which simply means that it takes less energy to move stuff about inside them than it does in other galaxies. As a result, moving in, around, and through such a tiny galaxy is quite easy to do, making them far more likely to be filled with streams and outflows of speedy charged particles known as galactic winds, which can flood such galaxies with little effort.

    These galactic winds can be powered by the ongoing process of star formation, which involves huge amounts of energy. New stars are springing into life within the bright, colorful ‘head’ of NGC 4861 and ejecting streams of high-speed particles as they do so, which flood outwards to join the wider galactic wind. While NGC 4861 would be a perfect candidate to study such winds, recent studies did not find any galactic winds in it.

    NOAA’s GOES-16 weather satellite sends first images of Earth

     
     
    Since the GOES-16 satellite lifted off from Cape Canaveral on November 19, scientists, meteorologists and ordinary weather enthusiasts have anxiously waited for the first photos from NOAA’s newest weather satellite, GOES-16, formerly GOES-R.
     
    The release of the first images today is the latest step in a new age of weather satellites. It will be like high-definition from the heavens.
     
     
     
    This 16-panel image shows the continental United States in the two visible, four near-infrared and 10 infrared channels on the Advanced Baseline Imager (ABI). These channels help forecasters distinguish between differences in the atmosphere like clouds, water vapor, smoke, ice and volcanic ash. (NOAA/NASA)
    
     
    The pictures from its Advanced Baseline Imager (ABI) instrument, built by Harris Corporation, show a full-disc view of the Western Hemisphere in high detail — at four times the image resolution of existing GOES spacecraft. The higher resolution will allow forecasters to pinpoint the location of severe weather with greater accuracy. GOES-16 can provide a full image of Earth every 15 minutes and one of the continental U.S. every five minutes, and scans the Earth at five times the speed of NOAA’s current GOES imagers.

    NOAA’s GOES-16, situated in geostationary orbit 22,300 miles above Earth, will boost the nation’s weather observation network and NOAA’s prediction capabilities, leading to more accurate and timely forecasts, watches and warnings.

    “This is such an exciting day for NOAA! One of our GOES-16 scientists compared this to seeing a new-born baby’s first pictures — it’s that exciting for us,” said Stephen Volz Ph.D. director of NOAA’s Satellite and Information Service. “These images come from the most sophisticated technology ever flown in space to predict severe weather on Earth. The fantastically rich images provide us with our first glimpse of the impact GOES-16 will have on developing life-saving forecasts.
     
     
     
     
    GOES-16 captured this view of the moon as it looked across the surface of the Earth on January 15. Like earlier GOES satellites, GOES-16 will use the moon for calibration. (NOAA/NASA)
     
    In May, NOAA will announce the planned location for GOES-16. By November 2017, GOES-16 will be operational as either GOES-East or GOES-West. Once operational, NOAA will use the satellite’s six new instruments to generate new or improved meteorological, solar, and space weather products.

    Second satellite in GOES series already in development

    Following on the heels of GOES-R will be, GOES-S, the second of four spacecraft in the series. GOES-S is undergoing environmental testing at Lockheed Martin’s Corporation facility in Littleton, Colorado, where it was built. A full set of environmental, mechanical and electromagnetic testing will take about one year to complete. The GOES-S satellite will be moved into the other operational position as GOES-17 immediately after launch and initial checkout of the satellite, approximately nine months after GOES-16.

    Breakthrough Initiative Are We Alone? VLT to Search for Planets in Alpha Centauri System

    Are We Alone?

    First a reproduction of an open letter , then a news report!

    Now is the time to find out


     
    Who are we?
    A mature civilization, like a mature individual, must ask itself this question. Is humanity defined by its divisions, its problems, its passing needs and trends? Or do we have a shared face, turned outward to the Universe?
    In 1990, Voyager 1 swiveled its camera and captured the ‘Pale Blue Dot’ - an image of Earth from six billion kilometers away. It was a mirror held up to our planet - home of water, life, and minds. A reminder that we share something precious and rare.
    But how rare, exactly? The only life? The only minds?
    For the last half-century, small groups of scientists have listened valiantly for signs of life in the vast silence. But for government, academia, and industry, cosmic questions are astronomically far down the list of priorities. And that lengthens the odds of finding answers. It is hard enough to comb the Universe from the edge of the Milky Way; harder still from the edge of the public consciousness.
    Yet millions are inspired by these ideas, whether they meet them in science or science fiction. Because the biggest questions of our existence are at stake. Are we the Universe’s only child - our thoughts its only thoughts? Or do we have cosmic siblings - an interstellar family of intelligence? As Arthur C. Clarke said, “In either case the idea is quite staggering.”
    That means the search for life is the ultimate ‘win-win’ endeavor. All we have to do is take part.
    Today we have search tools far surpassing those of previous generations. Telescopes can pick out planets across thousands of light years. The magic of Moore’s law lets our computers sift data orders of magnitude faster than older mainframes - and ever quicker each year.
    These tools are now reaping a harvest of discoveries. In the last few years, astronomers and the Kepler Mission have discovered thousands of planets beyond our solar system. It now appears that most stars host a planetary system. Many of them have a planet similar in size to our own, basking in the ‘habitable zone’ where the temperature permits liquid water. There are likely billions of earth-like worlds in our galaxy alone. And with instruments now or soon available, we have a chance of finding out if any of these planets are true Pale Blue Dots – home to water, life, even minds.
    There has never been a better moment for a large-scale international effort to find life in the Universe. As a civilization, we owe it to ourselves to commit time, resources, and passion to this quest.
    But as well as a call to action, this is a call to thought. When we find the nearest exo-Earth, should we send a probe? Do we try to make contact with advanced civilizations? Who decides? Individuals, institutions, corporations, or states? Or can we as species - as a planet - think together?
    Three years ago, Voyager 1 broke the sun’s embrace and entered interstellar space. The 20th century will be remembered for our travels within the solar system. With cooperation and commitment, the present century will be the time when we graduate to the galactic scale, seek other forms of life, and so know more deeply who we are.

    VLT to Search for Planets in Alpha Centauri System

    ESO has signed an agreement with the Breakthrough Initiatives to adapt the Very Large Telescope instrumentation in Chile to conduct a search for planets in the nearby star system Alpha Centauri. Such planets could be the targets for an eventual launch of miniature space probes by the Breakthrough Starshot initiative.
     
     
     
    ESO, represented by the Director General, Tim de Zeeuw, has signed an agreement with the Breakthrough Initiatives, represented by Pete Worden, Chairman of the Breakthrough Prize Foundation and Executive Director of the Breakthrough Initiatives. The agreement provides funds for the VISIR (VLT Imager and Spectrometer for mid-Infrared) instrument, mounted at ESO’s Very Large Telescope (VLT) to be modified in order to greatly enhance its ability to search for potentially habitable planets around Alpha Centauri, the closest stellar system to the Earth. The agreement also provides for telescope time to allow a careful search programme to be conducted in 2019.
    The discovery in 2016 of a planet, Proxima b, around Proxima Centauri, the third and faintest star of the Alpha Centauri system, adds even further impetus to this search.
    Knowing where the nearest exoplanets are is of paramount interest for Breakthrough Starshot, the research and engineering programme launched in April 2016, which aims to demonstrate proof of concept for ultra-fast light-driven “nanocraft”, laying the foundation for the first launch to Alpha Centauri within a generation.
    Detecting a habitable planet is an enormous challenge due to the brightness of the planetary system’s host star, which tends to overwhelm the relatively dim planets. One way to make this easier is to observe in the mid-infrared wavelength range, where the thermal glow from an orbiting planet greatly reduces the brightness gap between it and its host star. But even in the mid-infrared, the star remains millions of times brighter than the planets to be detected, which calls for a dedicated technique to reduce the blinding stellar light.
    The existing mid-infrared instrument VISIR on the VLT will provide such performance if it were enhanced to greatly improve the image quality using adaptive optics, and adapted to employ a technique called coronagraphy to reduce the stellar light and thereby reveal the possible signal of potential terrestrial planets. Breakthrough Initiatives will pay for a large fraction of the necessary technologies and development costs for such an experiment, and ESO will provide the required observing capabilities and time.
    The new hardware includes an instrument module contracted to Kampf Telescope Optics (KTO), Munich, which will host the wavefront sensor, and a novel detector calibration device. In addition, there are plans for a new coronagraph to be developed jointly by University of Liège (Belgium) and Uppsala University (Sweden).
    Detecting and studying potentially habitable planets orbiting other stars will be one of the main scientific goals of the upcoming European Extremely Large Telescope (E-ELT). Although the increased size of the E-ELT will be essential to obtaining an image of a planet at larger distances in the Milky Way, the light collecting power of the VLT is just sufficient to image a planet around the nearest star, Alpha Centauri.
    The developments for VISIR will also be beneficial for the future METIS instrument, to be mounted on the E-ELT, as the knowledge gained and proof of concept will be directly transferable. The huge size of the E-ELT should allow METIS to detect and study exoplanets the size of Mars orbiting Alpha Centauri, if they exist, as well as other potentially habitable planets around other nearby stars.

    More Information

    The Breakthrough Initiatives are a program of scientific and technological exploration founded in 2015 by Internet investor and science philanthropist Yuri Milner to explore the Universe, seek scientific evidence of life beyond Earth, and encourage public debate from a planetary perspective.
    Breakthrough Starshot is a $100 million research and engineering program aiming to demonstrate proof of concept for a new technology, enabling ultra-light unmanned space flight at 20% of the speed of light, and to lay the foundations for a flyby mission to Alpha Centauri within a generation.
    ESO is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. It is supported by 16 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre European Extremely Large Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.
