LEGO Classic Space: the robot final rebellion on the capital planet ousts the federation rule and replace with a techno republic and dictatorship (the final episode (for a while)) (AFOL toy hobby photography with droids, police and minifigures city MOC

dannyhennesy posted a photo:

On the Capital planet the rebellious droids had followed maily the Bat-Bot, but as time progressed his circuits had gone all mushy at 780 years or so without maintenance…

Several splinter groups all with their local bot leaders emerged such as the Che-bot, the traffic-light-robot and the Butt-bot, but none of these collected enough sentient circuits to call themselves a popular (or Animata) mass movement!

That was until a cyborg came along, one known as Jones, a long time prisoner and terrorist, his easy solutions to every problem rang well in the masses' auditory circuits!!!

His slogans and simple rhetoric were simple enough for the simple traffic-light to comprehend and cheer!

His language was full of hate towards the organics and especially the humans who were the most common races among the ruling class of the federation!!!

Despite being a “Fleshie” himself his message collected the angry enslaved
bot community by only weeks all rebellious robots except for a few fringe loonies had forgotten the old leaders…

One morning at Jones gave the signal…

All over the capital planet hordes and swarms of any form of mechanical sentient beings attacked first the police stations, then the Company boards running the planet and the federation as well as their starfleet…

Many died, especially the low level police and army! Many mechanicals died too, but their ranks were soon filled by Mutant fleshie allies of the lower levels who hated the Federation feudal society and upper classes as much as their technological allies…

The Federation state apparatus and ruling class, most of their fleet army fled when they knew the game was up, they activated the emergency escape plan and whole city blocks with important factories, administrational units, valuable assets and so on separated from the capital by hidden rocket engines and homed in their course to Mars…

On Mars the federation regrouped and formed their new society…

On the Capital planet, the robots proclaimed the first Techno-republic of the advanced inorganic civilization, the low level fleshies left behind, became slaves and their mutant allies got to rule their own minute chiefdoms as protectorates under the Techno-republic…

Jones was now the undisputed ruler of the capital planet, but the victory was a pyrros one since, all important buildings, all of value was now one Mars!

But as Jones put it:

Our proud race the Techno-species didn’t need the Fleshies administration, their infrastructure, their spaceships…

We shall start from scratch, with a new administration, a new order, every droid shall work at 4x speed than they did during human oppression since now we are free and the fleshies shall work twice as hard than the Techno-Race, until we have breed enough new fleshies so they can do all work!

Our future is bright and shiny like glistering shiny metal!

The snapshot seen here is from the first police station attacked in sector 45-34v-ss-g the first one to fall according to official techno-history!

Designers note:

I am sad to say that this is the last episode in this years-spanning space series… At least for a while, I will still post LEGO hobby stuff here but without a storyline, perhaps small designs and builds… and occasionally a story when I feel like it!!!

I would like to thank all who had been in this journey of our heros, but it has taken far to much time and effort and since the state of the world is as it is, I am spiraling down in another depression, I must stop it before I reach the abyss, so I have remove some stress out of my equation… I ended it in a cliffhanger so I can easily restart it when my mental health improves… I hope that won’t be forever???

I would love if someone used my characters or ideas, please send me a link if you do, I would love to read it or look at it!!!

But there will be more Lego, just in different format without long stories, I need to focus more on my art and to be honest that is the only time the mental pain eases, when I create!!!

Russia’s Behaviour Risks Weaponizing Outer Space

27 July 2020

Dr Beyza Unal

Deputy Director, International Security Programme

Mathieu Boulègue

Research Fellow, Russia and Eurasia Programme
With negotiations in Vienna between the US and Russia hoping to prevent the weaponization of space, how much do Russia’s satellites pose a threat to the peaceful use of outer space, ask Beyza Unal and Mathieu Boulègue?

Days before the publication of last week’s report into Russian activity in the UK, and the subsequent call from several UK parliamentarians for a swift response to the ‘Russian threat’, Russia tested a new anti-satellite weapon capability releasing a small projectile from its Kosmos-2543 sub-satellite.

Kosmos-2543, a small satellite contained inside a larger satellite, Kosmos-2542, and 'birthed’ into orbit in late 2019, recently came under scrutiny in January 2020 when it was reportedly caught ‘buzzing’ US spy satellites in Low Earth Orbit.

By releasing a small projectile from the Kosmos-2543 sub-satellite, the US claims that Russia has launched a new projectile into orbit with relatively high speed – estimated at around 500 km per hour – leading to concerns about the potential of Russia to develop this technology as a weapon to target foreign satellites.

It is not the first time Moscow has relied on a Russian doll – or matryoshka – approach to launching satellites into outer space. In October 2017, a sub-satellite, Kosmos-2521, was ejected from its main satellite, Kosmos-2519, into a high-speed object in low orbit.

The Russian Ministry of Defence has declared that its latest activity is just for ‘routine’ inspections and surveillance of Russia’s other space assets, with the government’s official statement avoiding recognizing the existence of the new object while, at the same time, Kremlin spokesperson, Dmitry Peskov, recalling Russia’s commitment for the ‘complete demilitarization’ of space.

While it is possible that Russia’s matryoshka satellites have indeed been developed to carry out routine repairs of Russia’s space fleet, they also have the potential to interfere with, and destroy, other satellites with such action needing to be considered a threat until Russia demonstrates otherwise.

Russia’s use of outer space

Russia is not the only state investigating anti-satellite weaponry capabilities. There is a wider trend (e.g. China, India, US) to demonstrate advanced space capabilities with nefarious, if not directly offensive, intent. But, for the past few years, Russia in particular, has been provocative in testing its space weapon capabilities. 

For example, in April 2020, Russia launched and tested into low orbit the PL-19 Nudol direct-ascent anti-satellite (DA-ASAT) interceptor missile system from the Plesetsk Cosmodrome demonstrating its space assets with potential offensive capabilities, in particular, Russia’s capacity to destroy satellites in Low Earth Orbit.

In addition, the satellites, Kosmos-2535 and Kosmos-2536, launched in July 2019, are also suspected to be operating beyond their official mission of studying Russian orbital assets. It is reported that these satellites conducted a close proximity activity, coming within one kilometre from each other, which led to the creation of orbital debris.

Russia’s space strategy

By exploiting asymmetric advantages in space, Russia seeks to leverage its capabilities against competitors in space and in other domains, falling in line with its wider military strategy as well as its current Federal Space Programme for 2016 to 2025.

Russian space activities also have a cyber and electronic warfare angle. With the help of remote-sensing capabilities, Russian spy satellites potentially seek to disrupt military and civilian satellite communications and navigation systems. Indeed, in 2018, French authorities publicly accused Russia of seeking to intercept communication satellites for French and Italian armed forces putting data transmission through Western civilian and military satellites at risk of interception.

Furthermore, earlier this year, both Kosmos-2542 and 2543 came within 160 kilometres of a US spy satellite, US KH-11, similarly to Russia ‘buzzing’ around the British Isles or submarine surveillance that Norway and Sweden have been subjected to recently.

Shadowing and tailing in space is regarded as spying and this recent anti-satellite weapon test is part of a trend which demonstrates Russia’s persistent space strategy for close-proximity operations with foreign countries.

Orbital hypocrisy

Despite Russia’s calls for a treaty to prevent the placement of weapons in outer space, there remains little international trust in Russia’s behaviour in space so far with a US-Russia Space Security Exchange meeting scheduled to take place in Vienna on 27 July to discuss outer space stability and security.

This is amid a backdrop of bilateral nuclear arms control talks on the extension of the extant nuclear weapons reduction treaty, New START, which is scheduled to expire in February 2021. There is no guarantee, however, that the talks will achieve anything especially since the future of outer space requires a wider multilateral dialogue with all parties involved – including China.

Anti-satellite tests (ASATs) are a particularly dangerous form of weapon. Not only do they create major vulnerabilities in a domain where so much of humanity depends on for navigation, communications and environmental monitoring, they are also primarily a target for destabilization and undermining global positioning information in times of crisis.

And, perhaps most significantly, they possess the highly destructive potential to create even more space debris in Earth’s orbits that endanger the peaceful use of satellites and could do serious damage to large parts of the economies of developed and developing countries.

Avoiding space warfare

Space is for all but there is a risk that it is being hijacked by a few. It is time to re-assert and reinforce the rules, principles and norms of responsible state behaviour in outer space enshrined in the 1967 Outer Space Treaty and its associated international agreements.

And, because the treaty specifically prohibits stationing nuclear weapons and other weapons of mass destruction in orbit or on celestial bodies, it is necessary to build on it to ban other types of weapons in space.

Space has been militarized since 1957 with the launch of Soviet satellite Sputnik. But the increasing weaponization of space adds more uncertainty, and unveils more vulnerabilities, that states need to address before space warfare becomes a reality.

Why Africa needs to be in space

Why Africa needs to be in space The World Today mhiggins.drupal 1 August 2022

From agriculture and navigation to banking and tele-education, satellite technology can have a huge impact on rapidly developing societies, says Val Munsami.

Africa’s socio-economic and environmental development is widely acknowledged as being crucial to its growth and long-term sustainability – and the prosperity of its more than one billion residents. 

Increasingly, though, attention is also turning to the contribution that the space industry can make to progress on the continent. Space-based products and services have a critical role to play in meeting national and continental priorities, as underpinned by the UN’s Sustainable Development Goals and the African Union’s Agenda 2063 – the bloc’s strategic framework for development, democracy and peace. 

With this in the mind of policymakers, the African Union’s space policy and strategy is embedded in Agenda 2063 as one of its 15 key programmes. It guides the sector’s development and the nascent African Space Agency, to become operational later this year from its headquarters in Egypt.


The continental agency is expected to leverage the benefits of space science and technology for socio-economic and environmental development. It will lead on bridging the space divide, especially for those countries that do not have a focus on, or activities in, space science and technology – and simultaneously inject some momentum into improving capabilities of existing national space programmes.

The African Union’s commitment to space has accelerated the growth of the African space industry. More than 20 national space agencies or space-related institutions have been established on the continent over the past five or so years. 

Our modern lifestyles are intimately dependent on space products and services. Meteorological and communication satellites are placed in geostationary orbits at an altitude of 36,000km above the equator. At this point above the Earth, they complete one orbit every 24 hours in the direction of the planet’s rotation, appearing, essentially, motionless – and providing a constant gaze on the same geographic location.

They provide a wealth of information that fuels the everyday services we take for granted, but that are essential for our everyday lives, from health to education to the economy.

From their vantage point, geostationary orbit satellites provide our daily weather reports, monitor climate-related cycles and offer a platform for near-instantaneous communications across the globe to relay multimedia, live sporting events and up-to-the-minute global news. 

This lightning-fast communication is also indispensable for tele-education and tele-medicine, by which professionals in urban areas can deliver educational content and health services to rural schools and clinics, respectively. Banking transactions also rely on telecommunication satellites to communicate between an automated teller machine and the data servers located at the bank. 

How satellites can detect disease

Other satellites are placed in low Earth orbits. These complete on average one polar orbit around the Earth every 100 minutes. Because the planet rotates across the plane of the orbit, such a satellite eventually covers the whole Earth, which is immensely useful for remote sensing and navigation and positioning applications. 

Remote sensing applications provide a myriad of products and services, including monitoring the state of our natural resources, observing ship traffic in our coastal economic zones and providing information for precision farming that can help a farmer decide, for example, when to irrigate and how much fertilizer to use.

They can also detect changes that might indicate encroaching water-borne diseases, aid peacekeeping missions and help ensure public safety and security. Navigation applications are vital for aviation and marine navigation, whereas positioning applications are important for safety-of-life services. 

The rich source of information derived from satellites is vital for evidence-based decision and policymaking

Another way that positioning applications in developing countries are put to good use is the assignment of geolocation addresses to dwellings in informal settlements where postbox addresses do not exist. This then allows the overlaying of key vector data about populations on to geophysical base maps. This type of data is vital for town planning in terms of how many schools and clinics are needed to serve the population, and the extent of the road, water, sanitation and electrical infrastructure needed.

The rich source of information derived from satellites, overlaid with in-situ data, is vital for evidence-based decision and policymaking. Datasets accessed from historical archives can be used to observe the time evolution of environmental and statistical data. 

When policy decisions are taken, we can utilize the same satellite and in-situ platforms to monitor progress after their implementation. The utility of data to inform decision-making is being enhanced through the adoption of AI and big-data analytics, which is placing key information at our disposal in near real time. 

It is therefore not surprising to notice the increasing focus on space science and technology activities on the continent. However, to ensure the effective uptake and utilization of space products and services, certain building blocks are needed to establish robust national and regional space ecosystems. 

Africa’s route into space

These ecosystems must include four primary elements to function: the human capital required to establish and operate the space initiatives; a significant industry base to capitalize on the commercial aspects of the space sector; the requisite infrastructure needed to support the space value chain; and international cooperation to ensure knowledge transfer and diffusion – so that we don’t have to reinvent the wheel.

To take advantage of the space ecosystem, Africa needs strong governance and institutional architectures


The applications and problem-solving innovations provided by space products and services are endless. To take advantage of this, Africa needs strong governance and institutional architectures. 

The evolution of the space ecosystem on the continent must be premised on key instruments such as a space policy – which areas to focus on and why – and a space strategy that outlines which programmes and performance indicators to pursue. 

The conceptualization of a space ecosystem is by no means a simple endeavour and there is certainly a dearth of skills and experience on the African continent to establish effective and relevant space ecosystems. 

There are many institutions leading efforts to build space capacity and skills on the continent, such as the International Space University in France, which offers programmes that provide a holistic overview of the complex global space sector, and the African Space Leadership Institute, which has been recently created to develop capacity in space policy, law and strategy. 

With the right approach, commitment and investment, Africa can rapidly change the fate of its citizens by effectively using space science and technology to support and drive its developmental agenda.
