STARLab. Portugal e a China investem €50 milhões para fabricar pequenos satélites em Matosinhos e Peniche



Nos últimos 15 anos o Instituto de Microssatélites da Academia de Ciências Chinesa foi responsável pelo lançamento de perto de 40 satélites no âmbito de missões científicas

hama-se STARLab e é um laboratório conjunto de investigação e desenvolvimento tecnológico para o Espaço e para os oceanos que vai ser criado por Portugal e a China. O projeto é revelado ao fim da manhã desta terça-feira pelo ministro da Ciência, Tecnologia e Ensino Superior, Manuel Heitor, à margem da Web Summit, que decorre no Parque das Nações, em Lisboa. E envolve um investimento de 50 milhões de euros nos próximos cinco anos para fabricar pequenos satélites em Matosinhos e Peniche.

O laboratório será financiado em partes iguais pelos dois países, sendo a componente portuguesa distribuída por igual entre o sectores público e privado. A Academia de Ciências Chinesa, por sua vez, será a responsável direta pelo investimento da China. O objetivo global é desenvolver tecnologias e sistemas de engenharia para melhorar o conhecimento, a gestão e a exploração sustentável dos oceanos e do Espaço. E prevê-se a abertura de centros de investigação em Portugal Continental e em Xangai, na China.

"A Academia de Ciências Chinesa é a instituição que a nível mundial está a investir mais na tecnologia dos pequenos satélites, um sector emergente", explica Manuel Heitor ao Expresso. O ministro acrescenta que na Europa "a China está a desenvolver um projeto do mesmo género no Luxemburgo".

O STARLab envolve também a empresa espacial portuguesa Tekever e o CEiiA – Centro de Engenharia e Desenvolvimento de Produto. O ministro revela que os pequenos satélites serão fabricados em Peniche, num novo Laboratório Colaborativo liderado pela Tekever, e no CEiiA em Matosinhos. Os laboratórios colaborativos juntam empresas, centros de investigação, instituições do ensino superior, autarquias, centros tecnológicos e associações. Já existem 20 em todo o país.

Tiago Rebelo, diretor para o Espaço e Engenharia Oceânica do CEiiA, afirma ao Expresso que o envolvimento deste centro no STARLab "vai catapultar-nos para um enorme mercado que é a China, país que tem um a grande experiência nesta área, com dezenas de microssatélites no Espaço e robôs de recolha de dados nos oceanos". Por outro lado, o novo projeto "irá reforçar toda atividade que o CEiiA já tem neste setor, em particular no contexto do futuro AIR Center e na observação dos oceanos, bem como trazer novas oportunidades de desenvolvimento tecnológico".

ACELERAR O CONHECIMENTO SOBRE OS OCEANOS E O ESPAÇO
“Estamos perante uma excelente oportunidade de acelerar o conhecimento sobre os oceanos e o Espaço e cumprir o nosso desígnio de estudo aprofundado do Atlântico", afirma Manuel Heitor. "O STARLab possui metas a nível científico que passam pelo estudo de fenómenos naturais e os seus potenciais impactos sistémicos e ambientais". Para tal "prevê o desenvolvimento de soluções tecnológicas baseadas, nomeadamente, em microssatélites e na sua integração com plataformas de exploração do mar profundo”.

Ao mesmo tempo, "o STARLab irá fortalecer uma parceria de longo prazo entre a China e Portugal nas áreas da ciência e tecnologia, passando a ser uma entidade de referência na Europa de colaboração com a Academia de Ciências Chinesa”.

A assinatura oficial entre os dois países que dará origem ao STARLab vai acontecer na visita oficial do Presidente da China a Portugal, prevista para o final do ano. Os objetivos do STARLab estão alinhados com o projeto do AIR Centre, o grande centro internacional de investigação a criar nos Açores que vai fazer abordagem integrada pioneira ao Espaço, atmosfera, oceanos, clima, energia e ciência de dados.

O novo Laboratório Colaborativo irá contar com a participação do Instituto de Microssatélites da Academia de Ciências Chinesa, que nos últimos quinze anos foi responsável pelo lançamento de perto de 40 satélites no âmbito de missões científicas, assim como do Instituto de Oceanografia da mesma Academia, especializado na avaliação de recursos, alterações climáticas e biodiversidade. Outros organismos na órbita da Academia de Ciências Chinesa podem também vir a trabalhar com o laboratório.

Do lado nacional, a iniciativa está a ser promovida pelo Ministério da Ciência, Tecnologia e Ensino Superior, através da Fundação para a Ciência e Tecnologia (FCT). A Tekever vai focar-se na área de Espaço e o CEiiA nos Oceanos. A atividade do STARLab irá envolver centros de investigação e universidades nacionais durante a fase de desenvolvimento.

Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects. NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts.

New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.
The Voyager 1 spacecraft is moving at 38,000 mph (61,000 km/h). This was mostly achieved with a chemical rocket but also with a gravitational slingshot. The Juno, Helios I and Helios II spacecraft reached speeds in the 150,000 mph range using gravitational boosts. The recently launched Parker Solar Probe will reach 430,000 mph using the Sun’s gravity.

China unveils new 'Heavenly Palace' space station as ISS days numbered


China unveiled a partial model of its manned space station at an aerospace fair in Zhuhai

China unveiled on Tuesday a replica of its first permanently crewed space station, which would replace the international community's orbiting laboratory and symbolises the country's major ambitions beyond Earth.


The 17-metre (55-foot) core module was a star attraction at the biennial Airshow China in the southern coastal city of Zhuhai, the country's main aerospace industry exhibition.

Outside, China's J-10 fighter jet and J-20 stealth fighter wowed spectators as they zoomed across Zhuhai's sky. Back inside, the country displayed its fleet of drones and other military hardware.

Crowds gathered around the cylindrical space station module representing the living and working quarters of the Tiangong—or "Heavenly Palace"—which will also have two other modules for scientific experiments and will be equipped with solar panels.

Three astronauts will be permanently stationed in the 60-tonne orbiting lab, which will enable the crew to conduct biological and microgravity research.

Assembly is expected to be completed around 2022 and the station would have a lifespan of around 10 years.

The International Space Station—a collaboration between the United States, Russia, Canada, Europe and Japan—has been in operation since 1998 but is due to be retired in 2024.


Once the International Space Station is retired in 2024, China will be the only country with manned space station

China will then have the only space station in orbit, though it will be much smaller than the ISS which weighs 400 tonnes and is as large as a football pitch.

Billions spent

The country announced in May that the lab would be open to "all countries" to conduct science experiments.

"There is no doubt that China will use its station in a similar way as the ISS partners are using their outpost: research, technology and as a stepping-stone for deep-space exploration," said Chen Lan, analyst at GoTaikonauts.com, a website specialised in the Chinese space programme.

Research institutes, universities, and public and private companies have been invited to propose projects. Some 40 plans from 27 countries and regions have been received, according to state media.

The European Space Agency has sent astronauts to China to receive training in order to be ready to work inside the Chinese space station once it is launched.

"I'm sure over time China will be successful developing partnerships," said Bill Ostrove, space analyst with US-based Forecast International consultancy.


The 17 metre long core module will be significantly smaller than the ISS

"Many countries, and increasingly private companies and universities, have space programmes, but cannot afford to build their own space station," he said.
"The ability to put payloads and experiments on a human spaceflight platform is extremely valuable."

Beijing is pouring billions into its military-run space programme, with plans to send humans to the Moon in the near future.

Citing China as a threat, US President Donald Trump has launched plans to create a new "Space Force" to give his country dominance over rivals in space.

Diverse space market

But China's space programme has encountered some glitches.

A space lab dubbed Tiangong-1 disintegrated as it plunged back to Earth in early April, two years after it ceased functioning.


China says its space station will be open to all countries

Chinese authorities denied that the lab—which was placed in orbit in September 2011 as a testing ground for the permanent station—was out of control.

A second lab, the Tiangong-2, was launched into orbit in 2016.

"Despite a lot of talk of the opposite, the United States remains the most dominant power in space right now," Ostrove said.

"The most likely scenario for the future is that China will emerge as one of the major space powers," he said.

But Russia, the European Space Agency, Japan and India will continue to play "major roles" in space exploration, while private firms are becoming increasingly important in the sector, Ostrove added.

"The space market is becoming more diverse," he said, "so it will be difficult for one or two countries or companies to dominate the field in the way the US and Soviet Union did during the Cold War."

SpaceX Is Fashioning a Miniature Big Falcon Rocket Out of a Falcon 9

Can't build something big without building something smaller first.



SpaceX is known for thinking big, and its Big Falcon Rocket might be the biggest of its most-audacious plans. But with the rocket primed for interplanetary missions still in development, SpaceX will test out its BFR technology with the help of one of its stalwart vessels: the Falcon 9.

CEO Elon Musk announced on Wednesday the company will build a "mini-BFR Ship" using its trusted Falcon 9, in an effort to asses the viability of the actual BFR.

Mod to SpaceX tech tree build: Falcon 9 second stage will be upgraded to be like a mini-BFR Ship

— Elon Musk (@elonmusk) November 7, 2018
The goal for the modification is June 2019, Musk said in a follow-up tweet. SpaceX eventually imagines the BFR replacing all current rocketry in its arsenal, including the Falcon 9, so building one in miniature form and having it fly in orbit could be a good test run.

Musk did not detail what, exactly, would be done to a Falcon 9 to make it more BFR-like. The two rockets will share some similarities, like the ability to launch multiple times. In September, the California-based company announced that it would change aspects of the BFR, most notably it's cargo spaceship called the Big Falcon Spaceship (BFS). Meant to hold 100 people, the BFS was changed to accommodate six engines—two for the atmospheric pressure of sea level, and four for the vacuum of space.

At the time, SpaceX president Gwynne Shotwell said she expected the BFS to begin short, unmanned "hopping" tests in late 2019. This new timeline for a mini-BFR would fit perfectly with these tests.

In a follow-up tweet, Musk said the tests would specifically look at how the mini-BFR's heat shield and mach control surfaces will hold up under the duress of launch and flight, elements that are difficult to test without actually escaping the Earth's orbit.

Won’t land propulsively for those reasons. Ultra light heat shield & high Mach control surfaces are what we can’t test well without orbital entry. I think we have a handle on propulsive landings.

China continues recoverable rocket efforts with vertical landing flight test


A test vehicle for vertical landing and guidance control technology developed by facilities under the main Chinese space contractor CASC. Beijing Aerospace Automatic Control Institute

China has continued recent moves towards recovering and reusing its space launch vehicles with a small scale verification test of vertical landing and navigation and guidance control technology.

The test (Chinese) was carried out on October 29 by the Beijing Aerospace Automatic Control Institute, also referred to as the 12th research institute under the China Academy of Launch Vehicle Technology (CALT).

CALT is a major launch vehicle designer and maker, as well as one of the academies, under the China Aerospace Science and Technology Group (CASC), the main contractor for the Chinese space programme.

From the footage and online commentary it appears the test vehicle uses jet engines rather than rocket propulsion for landing, with the focus on testing the navigation and guidance control technology for vertical takeoff, vertical landing (VTVL) launch vehicles currently under development.

The institute says it will follow up the tests in order to assist the development of a reusable space transportation system.

China's moves towards reusable launchers
Following the successful development of such capabilities in the Falcon 9 and Falcon Heavy rockets, China and others have been looking into the technological feasibility and economic benefits of landing, recovering and reusing rocket stages.

The Shanghai Academy of Spaceflight Technology (SAST), a subsidiary of CASC and maker of launch vehicles and spacecraft, is developing a reusable variant of the expendable light-lift Long March 6 with the aim of reducing launch costs by around 30 percent.

CALT is meanwhile working on a larger Long March 8 rocket with similar VTVL capabilities for its first stage and, possibly, boosters, seeking to test fly the 3.35-metre diameter core Long March 7-derivative launcher around 2020.

Practical steps towards recoverability, particularly related to the issue of safety following launch from China's inland launch sites, have been taken in the last couple of months.

The boosters from a Long March 3B launch on October 15 carried data logging and active tracking equipment for tests to determine the altitude and timing for future parachute landings.

In September CASC also tested the use of a parafoil on the payload fairing with the aim of improving accuracy of its return to Earth so as to prevent debris landing on people and property, as well as potentially eventual reusability.

A China National Space Administration (CNSA) official said in September that development of reusable rocket stages and boosters is mainly related to 'safety', rather than stating the economics of launch as a factor.

Meanwhile Chinese space launch startup Linkspace appears close to testing a tech demonstrator reusable rocket similar in utility to the Grasshopper rocket SpaceX used in its development of the Falcon 9 launch vehicle.
