Spinlaunch Plans on Throwing Satellites into Orbit

December 6, 2021

This video from the YouTube channel Interesting Engineering describes the plans for a very remarkable satellite launch system developed by Spinlaunch, a company I really don’t know anything about. It seems from this video that they’ve built a 157 metre vertically inclined centrifuge as a precursor for one they hope to build, which will be three times larger and used as a satellite launch system. Instead of sending satellites conventionally into space with rockets, the Spinlaunch system will throw them into space instead. The full size system will also use rockets, although they will only fire at an altitude of 61 km above the Earth to place 200 kilo satellites in orbit. The video looks forward to the new system being more sustainable and ecologically friendly than conventional launch systems.

It’s an interesting concept, and the idea of throwing vessels into space I think goes right back to Robert Goddard, the founder of American rocketry. From childhood Goddard wanted to send people to Mars, hence his determination to develop the technology to get people into space. Before settling on rockets, Goddard apparently thought about devices to throw ships into space. And there are indeed a number of problems with using rockets as launch systems. Space and Futurism YouTuber Isaac Arthur, in his video about spaceports, points out that currently launch sites have to be sited well away from any cities because of the sheer noise and power of the rockets. It’s possible that the Spinlaunch system may be able to solve this problem if such centrifuges are quieter than rocket engines. Glancing down the internet entries for similar videos, it seems that not everyone is impressed with the company’s claims. Atheist science vlogger and anti-feminist Thunderfoot has put up a video which suggests that he’s busted their claims. Other space vloggers, like Scott Manley, seem much more impressed with them, and the blurb for the video states that it’s been successfully tested. I honestly don’t know if the idea will work in practice, but it’ll be interesting to see if it ever takes off (pun intended).

The Young Turks on Fox Lies over Obama Nuclear Deal with Iran

April 9, 2015

I’ve put up a number of videos recently of The Young Turks internet news programme reporting the negotiations between Obama and Iran about stopping the Islamic Republic’s nuclear programme. The Americans are understandably worried about the Iranian nuclear programme, which is currently directed towards generating domestic electricity, being turned to developing nuclear weapons instead.

These talks, which are intended to guarantee peace and prevent another nuclear arms race in the Middle East, are extremely unpopular with the Republicans. Several of the Turks’ videos I’ve posted on this report the Repugs stubborn opposition to the talks and their attempts to undermine them with a letter to the Iranian president himself.

In the video below, the Turks’ anchor Cenk Uyghur, explains how the talks have been successful for America. In return for lifting the sanctions, the Iranians have promised to scale back massively their nuclear programme. The plutonium stocks, which could be used to develop bombs, have been removed. The number of centrifuges have been reduced from 19,000 to 6,000. They have also agreed to give up 97 per cent of their stockpile of enriched uranium. The International Energy Authority has also been given full rights of access and inspection.

This is a very, very good deal. And as you’d expect, the Republicans are resolutely against it.

Uyghur here goes on to comment on Fox News’ report on the talks by their expert, Katie MacFarlane. She claims this is merely a paper agreement, and talks about how the Iranians still chant ‘Death to America’ and demand the annihilation of Israel.

Now Uyghur points out that this is far more than ‘a pinkie agreement’. It’s backed by a number of other countries, apart from America and Iran.

But the Repugs don’t want a negotiated peace. They want war, and an invasion of Iran.

There are several reasons why the Repugs want to invade Iran. The country is deeply hostile to both American and Israel. The Iranians, as a Shi’a nation, are backing the Shi’a population in Iraq and aiming to gain influence there through them. There are also reports that they are backing the Houthi rebels in Yemen, though this is unconfirmed.

However, as the Sisters of Mercy sang, ‘The real truth is never spoken’. I think a major reason why the Repugs want to invade Iran is the self-same one that motivated their invasion of Iraq: Iran is an oil-rich country, which won’t allow outsiders to own its industries. The oil industry was nationalised in Iran after the 1979 Revolution. The mullahs involved have massively enriched themselves. The regime has also passed laws preventing foreigners from owning Iranian companies. Forbes have placed Iran at the top of their list of countries that don’t allow free trade.

When Mossadeq, the then prime minister, attempted to nationalise the oil industry in the 1950s, he was overthrown in a CIA backed coup that inaugurated the Shah’s White Revolution. This led to eventual proscription of all opposition parties and autocratic rule by the Shah himself. The Iranian oil industry was dominated by Anglo-Persian Oil, or British Petroleum, now BP. The Iranians themselves received little in return for Britain’s exploitation of their oil wealth, and the Iranian workers were paid much less than their British counterparts.

British domination of the oil industry was massively resented, and Britain’s interference in the country’s affairs since the 19th century has been and continues to be a source of bitterness. There’s an Iranian saying, ‘If you find a stone in your path, it was put there by an Englishman’. Mossadeq’s administration and his nationalisation of the oil companies was extremely popular. His fall, and the political repression that followed, was one of the major factors leading to the Islamic Revolution.

It looks to me very much like Iran’s oil wealth is still coveted by Big Oil, who would like to invade the country and grab it for themselves. All under the guise of safeguarding international peace and bringing the country democracy. Just like they did in Iraq.

And look how successful that was.

The last thing the Middle East, Iran, Britain and America need is another war. The chaos and bloodshed in the region is bad enough as it is, without extending the war into Iran.

Far too many lives have already been lost, and there have been too many coffins going past Royal Wotton Bassett draped with flags, let alone the hundreds of thousands, if not millions, killed and left homeless by the war.

It’s time any talk about war with Iran was shown up as the dangerous nonsense it is.
