Japanese archipelago

ESA kosmose uudised - 17. January 2020 - 11:00
Image:

The Copernicus Sentinel-3 mission takes us over the Japanese archipelago – a string of islands that extends about 3000 km into the western Pacific Ocean.

While the archipelago is made up of over 6000 islands, this image focuses on Japan's four main islands. Running from north to south, Hokkaido is visible in the top right corner, Honshu is the long island stretching in a northeast–southwest arc, Shikoku can be seen just beneath the lower part of Honshu, and Kyushu is at the bottom.

Honshu’s land mass comprises approximately four-fifths of Japan’s total area. Honshu’s main urban areas of Tokyo, Nagoya, and Osaka are clearly visible in the image. The large grey area in the east of the island, near the coast, is Tokyo, while the smaller areas depicted in grey are the areas around Nagoya and Osaka.

Honshu is also home to the country’s largest mountain, Mount Fuji. A volcano that has been dormant since it erupted in 1707, Mount Fuji is around 100 km southwest of Tokyo and its snow covered summit can be seen as a small white dot.

The Sea of Japan, also referred to as the East Sea, (visible to the west of the archipelago) separates the country from the east coast of Asia. The turquoise waters surrounding the island of Hokkaido can be seen at the top of the image, while the waters in the right of the image have a silvery hue because of sunglint – an optical effect caused by the mirror-like reflection of sunlight from the water surface back to the satellite sensor.

Sentinel-3 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus environmental monitoring programme. Each satellite’s instrument package includes an optical sensor to monitor changes in the colour of Earth’s surfaces. It can be used, for example, to monitor ocean biology and water quality.

This image, which was captured on 24 May 2019, is also featured on the Earth from Space video programme.

ExoMars Rover completes environmental tests

ESA kosmose uudised - 16. January 2020 - 10:30

The Rosalind Franklin rover of the joint ESA-Roscosmos ExoMars mission completed a series of environmental tests at the end of 2019 at Airbus, Toulouse, France. This included final thermal and vacuum tests where the Rover is heated and cooled to simulate the temperatures of its journey through space and on the surface of Mars. For example, Rosalind Franklin can expect temperatures dropping to –120°C outside, and –50 °C inside the rover once on Mars. It must also be able to operate in less than one hundredth of Earth’s atmospheric pressure – and in a carbon dioxide-rich atmosphere.

Last year the ‘structural and thermal model’ of the rover successfully completed a rigorous environmental test campaign; the latest round of tests subjected the real flight-model to the simulated space environment.

Now the focus moves to final checks on the rover systems. This includes checking the alignment of instruments working together, such as the imaging systems, and a final functional test of the integrated system after the environmental campaign. Once these verifications on the rover are completed, a functional check of the interfaces with the surface platform and descent module that will deliver it safely to the surface of Mars will be performed at Thales Alenia Space, Cannes, France.

The primary goal of the mission is to determine if there is or there has ever been life on Mars, and to better understand the history of water on the planet. The rover will seek out interesting geological locations to examine with its scientific tools and to drill to retrieve underground samples, on a quest to tackle these questions.

The mission is foreseen for launch in the launch window 26 July–11 August 2020 on a Russian Proton-M rocket with a Breeze-M upper stage from Baikonur, Kazakhstan, arriving at Mars 19 March 2021.

Heavy rainfall has triggered flooding in southern Iran, particularly in the Sistan and Baluchestan, Hormozgan and Kerman provinces. The downpour has led to blocked roads and destroyed bridges, crops and houses – displacing thousands of people.

This image, captured by the Copernicus Sentinel-2 mission, shows the extent of the flooding in the Sistan and Baluchestan province on 13 January 2020. Flooded areas are visible in brown, while the flooded villages are highlighted by dotted circles. Sediment and mud, caused by the heavy rains, can be seen gushing from the Bahu Kalat River, Iran, and Dasht River, Pakistan, into Gwadar Bay.

Zoom in to view the image of the floods at its full 10 m resolution.

The flooding has also affected Zahedan, as well as Konarak, Saravan, Nik Shahr, Delgan, Bazman, Chabahar, Zarābād and Khash.

In response to the flood, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.

High-gravity water waves

ESA kosmose uudised - 15. January 2020 - 9:37
Image:

What might look like jelly being stirred is actually water subjected to 20 times normal Earth gravity within ESA’s Large Diameter Centrifuge – as part of an experiment giving new insight into the behaviour of wave turbulence.

This research, led by Stéphane Dorbolo of University of Liège and Eric Falcon of CNRS and University of Paris, has been published in the prestigious Physical Review Letters.

Wave turbulence occurs anywhere where a set of random waves interact with each other – from the ocean to the atmosphere, or in plasmas – but the exact mechanisms behind it are only dimly understood. For surface waves on a liquid, gravity dominates the behavior at low frequencies, while ‘capillary action’ based on surface tension becomes more important at high frequencies.

To increase the range of frequencies where waves are dominated by gravity, the researchers conducted their experiment in the ESA’s Large Diameter Centrifuge (LDC) where they can create effective gravity levels up to 20 times that of Earth’s gravity.

Within this extended range, the result was a surprise: the typical timescales of wave interactions and dissipation did not depend of the wave frequency, as predicted theoretically.

Instead these timescales are set by the longest available wavelength within the system – namely the size of the container the waves occur within, an effect that current wave turbulence theories does not take into account.

Prof. Falcon explains: “This result suggests that ‘container’ size needs to be considered in studies of water waves within an ocean—as well as atmospheric waves on Earth and magnetically confined plasma waves as in fusion experiments.

 “Notably, this experiment serves to complete the scientific picture of how gravity has an impact on surface wave turbulence, because tuning the gravity level to an opposing low value has already been performed in experiments in zero-G parabolic flights in 2009 and more recently aboard the International Space Station in 2019. This has allowed us to successfully observe pure capillary wave turbulence with no contribution from gravity.”

Operating within a sci-fi style white dome, the LDC is an 8-m diameter four-arm centrifuge that gives researchers access to a range of hypergravity up to 20 times Earth gravity for weeks or months at a time. At its fastest, the centrifuge rotates at up to 67 revolutions per minute, with its six gondolas placed at different points along its arms weighing in at 130 kg, and each capable of accommodating 80 kg of payload.

The LDC was made available for this experiment through the Continously Open Research Announcement of the SciSpace Programme, supported by ESA’s Directorate of Human and Robotic Exploration.

Uuringu “Eesti välispoliitika mõju ja kuvand Euroopa Liidus” kokkuvõttes toovad autorid välja nii üldised poliitikasoovitused kui ka täpsemalt ettepanekud julgeoleku- ja kaitsepoliitikas, idapartnerluses ning lõunapartnerluses ja arengukoostöös. Muu hulgas soovitavad nad:

  • hoida senist Eesti kui konstruktiivse partneri kuvandit,
  • tugevdada Euroopa Liitu kuuluvate Põhjamaade ja Balti riikide koostööd,
  • pöörata erilist tähelepanu sidemete tugevdamisele Prantsusmaa ja Saksamaaga,
  • panustada rohkem Venemaa-teemalisse oskusteadmisse,
  • jätkata aktiivset idapartnerite toetamist,
  • sõnastada selgelt Eesti arengukoostöö eesmärgid ja tegevuskava.

Uuring „Eesti välispoliitika mõju ja kuvand Euroopa Liidus“ toetus Euroopa Välissuhete Nõukogu sarnasele uuringule, mille 2018. aasta väljaanne asetas Eesti 28 liikmesriigi pingereas mõjukuse poolest 12. kohale. Soome paigutus selles kohale 11, Leedu 21 ja Läti 22. Seda materjali täiendasid 2019. aasta juulist kuni novembrini läbi viidud 52 anonüümset intervjuud, millest 24 tehti Eesti diplomaatide ja ametnike, 18 liikmesriikide diplomaatide ning 10 Euroopa Liidu institutsioonide ametnikega.

Eesti Välispoliitika Instituudil valmis uuring Eesti välispoliitika mõjust ja kuvandist Euroopa Liidus

Diplomaatia.ee – news - 15. January 2020 - 2:26

„Vaatamata piiratud ressurssidele on Eesti kuvand ja mõju Euroopa Liidus tugev. Eesti on mõjutanud Euroopa Liidu Venemaa-poliitikat, idapartnerlust ja kaitsekoostööd. Eriti paistab Eesti silma digiühiskonna ja küberjulgeoleku arendamisel,“ võtab kokku RKK Eesti Välispoliitika Instituudi direktor Kristi Raik, üks uuringu autoreid. „Eesti on ühendav lüli Balti riikide ja Põhjala koostöös. Sageli pöörduvad teiste riikide diplomaadid ja ametnikud just Eesti poole, kui on soov kaasata Balti riikide ühist arvamust,“ märkis ta.

Raiki hinnangul paistis uuringust siiski ka murenoote. „Eesti senist tugevat kuvandit varjutavad sisepoliitilised tõmbetuuled ja valitsusest tulevad vastuolulised signaalid,“ nentis ta.

Uuringu kokkuvõttes toovad autorid välja nii üldised poliitikasoovitused kui ka täpsemalt ettepanekud julgeoleku- ja kaitsepoliitikas, idapartnerluses ning lõunapartnerluses ja arengukoostöös.

Huygens landing spin mystery solved

ESA kosmose uudised - 14. January 2020 - 19:00

Fifteen years ago today, ESA’s Huygens probe made history when it descended to the surface of Saturn’s moon Titan and became the first probe to successfully land on another world in the outer Solar System. However, during its descent, the probe began spinning the wrong way – and recent tests now reveal why.

Up in smoke

Another pair of eyes provides a sobering perspective on the fires ravaging Australia. ESA astronaut Luca Parmitano took images such as this one on 12 January from his vantage point of the International Space Station.

From satellite imagery tracing smoke and pollution, to images from the ground depicting apocalyptic red skies, there is no denying the fires’ devastating effect.

Starting in New South Wales and extending into Victoria, the ferocious bushfires have been raging since September and are fuelled by record-breaking temperatures. In the midst of a climate crisis, 2019 was the hottest year on record in Australia and with drought and wind, the fires have raged beyond seasonal expectations.

Winds have blown smoke over New Zealand and crossed the South Pacific Ocean, even reaching Chile and Argentina.

A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished.

Damage to wildlife notwithstanding, the fires have had a serious effect on air quality. Earth observation satellites like Copernicus Sentinel-5 Precursor has traced increased concentrations of carbon monoxide in the past months along Australia’s southeast coast.

This image was taken as the Station flew above Fraser Range, in Western Australia, near the Dundas Nature Reserve.

Luca posted images of the fire to social media and said: “Talking to my crew mates, we realised that none of us had ever seen fires at such terrifying scale”.

Astronaut photographs of Earth from space complement satellite imagery, allowing experts and the general public more insight on global events.

Like Luca, the world continues to monitor the fires. If there is a silver lining around the smoke, it is the increased awareness of and calls for urgent action on climate change that is continuing to sweep the globe.
