I like anything that is like an obstruction, something that I have to act through is good. -- Peter Sarsgaard
Who has recently visited Riga - 2023 - must have noticed the large excavation works in the area between the bus station and the railway station.. What is happening here?
Rail Baltica is the Project of the Century or the largest Baltic-region infrastructure project in the last 100 years
It is a greenfield rail transport infrastructure project with a goal to integrate the Baltic States in the European rail network. The project includes five European Union countries – Poland, Lithuania, Latvia, Estonia and indirectly also Finland. It will connect Helsinki, Tallinn, Pärnu, Riga, Panevežys, Kaunas, Vilnius, Warsaw. The Baltic part of the Rail Baltica project is referred to as the Rail Baltica Global Project. Its total length in the Baltic States is 870 kilometres (540 mi), with 213 kilometres (132 mi) in Estonia, 265 kilometres (165 mi) in Latvia, and 392 kilometres (244 mi) in Lithuania
As a result of the implementation of the Rail Baltica project, a modern, multi-modal traffic hub will be created at the centre of Riga, which will increase mobility, safety, accessibility and also provided new features to Riga, visually and functionally connecting parts of the city thus far separated by the railway embankment as well as conveniently connecting both banks of the Daugava River for pedestrians and cyclists by a new railway bridge.
Happy Truck Thursday!
For Macro Mondays "Numbers" theme. A mechanical integrator is a complex device that was used to calculate ship's stability before digital computers became practical. The complete device is similar to this image: commons.wikimedia.org/wiki/File:Mechanical_integrator_CHM...
The lens used was an old manual Zuiko 80mm f/4 macro on a sliding extension tube and micro 4/3's adapter, in spite of what the exif info states. Four Olympus high res shots were stacked in Photoshop. I would of liked to gotten one more but ran of focus adjustment.

L’île Louët se trouve au nord-est de la commune de Carantec. Elle se trouve en baie de Morlaix, à la sortie de la rade de Morlaix et plus précisément entre la pointe de Penn-al-Lann et le château du Taureau.
Le château du Taureau
À la suite d'une attaque de Morlaix par la flotte anglaise en 1522, il est décidé de construire un fort en baie de Morlaix. Toutefois, pour construire ce type de bâtiment sur la côte, il faut une autorisation du roi accordée par François Ier sur intervention du duc d'Étampes en 1542. Mais aucun financement royal n'est prévu. Le fort doit être construit sur les deniers des Morlaisiens qui seront remboursés plus tard, lorsque les finances du royaume le permettront. À titre de compensation, le Roi leur octroie le privilège de nommer le gouverneur du fort ainsi que sa garnison tout en assurant son équipement et son traitement. Ce privilège se révèle fort couteux, ainsi, en 1620, le budget alloué à la gestion du fort est de 18 000 livres.
En 1660, le Roi Louis XIV reprend le fort aux Morlaisiens et l'intègre dans le système de défense du royaume.
Vauban, ingénieur-architecte visita le château en avril 1689 et le trouva en fort mauvais état. Dans un rapport daté du 6 avril 1689, Vauban fait une description du fort primitif avant de donner son projet pour la reconstruction ; c'est ce projet général et ces idées qui seront utilisés jusqu'à l'achèvement du château en 1745. « Faire tout de pierre de taille. Choisir ces pierres des meilleures de l'Isle Calot qui tiennent bien leur arête, les tailler très proprement sur les faces» ordonne Vauban en 1689. La tour Française, même si elle est en bon état au niveau de sa maçonnerie, fait l'objet des bons soins de l'ingénieur. La tour d'artillerie devant assurer la défense du fort pendant sa reconstruction. Vauban propose de changer les deux planchers et leurs corbeaux de pierres de taille pour les ancrer dans le vieux mur, de réparer toutes les embrasures de la tour et de les doter de sabords.
Du reste de l'édifice, il veut construire un nouveau fort de « bonne et solide maçonnerie à chaux et sable ». Son profil « doit être fort et robuste, tant à raison des coups de mer dont il sera terriblement battu que de la grande hauteur qu'il est nécessaire de lui donner tant pour le rendre inaccessible aux entreprises de basse mer, que pour lui donner fleuron supérieur à celle de tous les vaisseaux qui passeront près ». La tour Française dominera l'ensemble du nouveau fort. Les quatre casemates à canons de l'ancien fort seront « déménagées », une nouvelle batterie basse voûtée de « pierres ardoisines » remplacera l'ancienne. Les basses embrasures sont destinées, selon les propres termes de Vauban, « contre le dehors à tenir du mousquet ».
Les travaux du nouveau fort du Taureau approuvés par Vauban commencent au printemps 1689.
Ce sont les ingénieurs Siméon Garangeau et Frézier qui mènent la reconstruction à son terme.
Garangeau meurt en 1741 à l'âge de quatre-vingt-quatorze ans, avant d'avoir pu terminer le château du Taureau. La dernière phase des travaux commence en 1741 et s'achève en 1745. La réalisation des plans d'achèvement du fort est donc confiée à Amédée François Frézier, ingénieur architecte du Roi qui collabore déjà, depuis 1717, au chantier. Le château fut totalement achevé en 1745.

Louët island
Louët island lies northeast of the town of Carantec. It is located in the bay of Morlaix, at the exit of the bay of Morlaix and more precisely between the tip of Penn-al-Lann and castle of Taurus.
Le château du Taureau
Following a Morlaix attack by the English fleet in 1522, it was decided to build a fort in the bay of Morlaix. However, to build such buildings on the coast, you need a license granted by King François Ier. Licence was granted in 1542 after an intervention of the Duke of Etampes. But no royal funding is provided. The fort was to be built on the money of Morlaisiens that will be repaid later when the kingdom's finances allow. As compensation, the King granted them the privilege of naming the governor of the fort and its garrison while ensuring its equipment and its treatment. This privilege is proving very expensive and, in 1620, the budget allocated to the management of the fort was 18 000 pounds.
In 1660, King Louis XIV takes back the fort from the Morlaisiens and integrates it into the realm of defense.
Vauban, architect-engineer visited the castle in April 1689 and found him in very bad condition. In a report dated 6 April 1689, Vauban give a description of the original fort before giving his project for reconstruction; this is the general project and ideas that will be used until the completion of the castle in 1745. "Doing all of stone. Choose the best stones on Isle Calot, hold their edge well, cut very neatly on the faces "ordered Vauban in 1689. The artillery tower was to defend the fort during its reconstruction. Vauban proposed to change the two floors and cut stone corbels to anchor in the old wall, repair all the embrasures of the tower and equip them with ports.
On the other part of the building, he wants to build a new fort of "good, solid masonry lime and sand." Profile "to be strong and robust, both because of the heavy seas which will be terribly beaten as the great height it is necessary to give so much to make it inaccessible to low water businesses, and give her flagship greater than that of all the vessels that pass by. " The French round will dominate the entire new fort. The four casemates of the old fort guns will be "relocated", a new vaulted low battery "ardoisines stones" will replace the old. The low doorways are intended, in the words of Vauban, "against the outside to hold the musket."
Work on the new high Taurus approved by Vauban beginning in spring 1689.
These are Simeon Garangeau Frézier and engineers who lead the reconstruction to an end.
Garangeau died in 1741 at the age of eighty-four, before he could finish the castle of Taurus. The last phase of work begins in 1741 and ends in 1745. The realization of the completion of the fort plans is entrusted to François Amédée Frézier King's architect engineer who is already working since 1717 on site. The castle was fully completed in 1745.

Berlin, Bernauer Straße
Architects: Kohlhoff & Kohlhoff (1998)
In April 1994, the German federal government, represented by the German Historical Museum, held a competition for the design of a national monument for the victims of the Berlin Wall and the German division that was to be erected at the historical site on Bernauer Strasse.
In July 1995 the federal government, which hosted the competition, decided that the design proposal by Kohlhoff & Kohlhoff should be realized. This design called for the integration of the remaining evidence of the original border fortifications at Bernauer Strasse, and sought to reinforce and embellish them through artistic means.
The monument, two steel walls enclosing a preserved 70-meter long section of the original border fortifications was inaugurated in August, 1998.

The fuzzy objects in this image are all galaxies.
This stretched region of galaxies is named Markarian's Chain. It is part of the Virgo Cluster which itself is a part of the Virgo Supercluster. Our Milky Way belongs to the so called Local Group which is also part of the Virgo Supercluster. So these galaxies are kind of our neighbors if you will.
Overall integration time in this image is 53x120 seconds totalling in 1h 46m exposure time. Shot with my little 72/432mm refractor and a OSC (IMX571).

A specially upgraded radio-frequency chamber in ESA’s technical heart is testing what is set to become the smallest radar system to be flown in space, hosted aboard a breadbox-sized spacecraft.
Scheduled to fly to the Didymos binary asteroid system with ESA’s Hera mission for planetary defence in 2024, the compact radar aboard the Juventas CubeSat will perform the first ever radar sounding inside an asteroid. Juventas will peer up to 100 m deep within the 160-m-diameter Dimorphos moonlet of the 780-m-diameter Didymos asteroid.
CubeSats are mini-satellites built up from standardised 10-cm boxes. Juventas is a ‘6-unit’ CubeSat, measuring 10x20x30 cm, while its quartet of radar antennas measure 1.5 m long each. So the test campaign includes a structural model of the Juventas CubeSat, to evaluate how the body of the miniature spacecraft might affect the radar signals.
The test campaign is taking place inside the ‘Hybrid European Radio Frequency and Antenna Test Zone’ or Hertz chamber at ESA’s European Space Research and Technology Centre (ESTEC) in the Netherlands. However testing here only became feasible after a skillful upgrade.
“An essential element of anechoic test chambers like Hertz are the radio-absorbing foam spikes lining the inside walls, allowing tests to mimic the infinite void of space,” explains ESA antenna engineer Paul Moseley.
“But typically Hertz can only test down to 400 MHz, while Hertz’s main antennas will radiate at 60 MHz. At this frequency the spikes no longer absorb signals, so instead of a dark room the chamber would be turned into a hall of mirrors, throwing out multiple radio reflections that interfere with the accuracy of our measurements.”
ESA’s Hertz team worked with MVG in Italy to devise a new setup making lower frequency testing possible, initially as part of a general upgrade but then specially targeted to enable Juventas testing.
Paul adds: “It’s a combination of hardware and software that allows us to measure in this environment but still reconstruct the correct results, including fibreglass support towers that are transparent to antennas and software that combines measurements made at many different points across the room, in order to cancel out the reflection effects.”
Franco Perez Lissi of ESA’s CubeSats Systems Unit is overseeing the Juventas testing: “We’re measuring the radiation pattern in a full sphere surrounding the antennas- the results of which should also be very useful for Juventas’s critical design review, taking place next month – as well as the total radiated power. This entire campaign additionally serves as a dress rehearsal of sorts for the flight model of Juventas, which is scheduled to be tested here in early 2023.”
The radar aboard Juventas is developed from the Rosetta spacecraft’s CONSERT radar system, which peered into the interior of Comet 67P/Churyumov–Gerasimenko. It is a synthetic aperture radar design, meaning it will take advantage of Juventas’s orbit 3 km above the surface of Dimorphos to integrate together multiple signal reflections and resolve them into images.
“We are proud to see Rosetta’s legacy living on in the next generation of deep-space missions,” adds Alain Herique of the University of Grenoble, Principal Investigator of Juventa’s JuRa low-frequency radar.
Juventas is being led for ESA by GomSpace company in Luxembourg with GMV in Romania, with its radar developed by the Planétologie et d'Astrophysique de Grenoble group at the University Grenoble and Technical University Dresden, with Astronika in Poland constructing the antennas and EmTroniX in Luxembourg contributing the signal generation system.
Hera will also be embarking a second deep space CubeSat, the Italian-led Milani, which will employ a multispectral imager to prospect the asteroid’s surface composition. Hera will be preceded to the Didymos asteroids by NASA’s DART spacecraft which will perform a test deflection of the smaller body. DART is due for launch next Wednesday, 24 November.

NASA science research on the International Space Station reached an extraordinary milestone June 14. The vital, versatile EXPRESS Racks – properly known as “EXpedite the PRocessing of Experiments to the Space Station” multipurpose payload shelving units – logged 1 million hours of combined powered duty on station. That’s the equivalent of nearly 115 years’ worth of scientific research completed in just two decades. In this image, NASA astronaut Kayla Barron monitors experiments in one of the International Space Station’s 12 EXPRESS Racks during Expedition 66, which ran from October 2021 to March 2022. As many as 100 experiments at a time can be simultaneously conducted in the station’s full complement of racks, helping NASA achieve 1 million hours of powered EXPRESS Rack duty between 2001-2022.
