Drone Wars

Drones

Mauricio loves remote control aircraft. When I bought a model plane for my son he was the first round to see it, he told me how to strengthen the wings, and recounted tales of daredevil antics and crashes in the heart of South America.

Now he wants to get a license to pilot a drone, because now in Italy where he lives you need a license, which is not the case in the USA.

Drone Use and the Law

Drone use is becoming ever more common, but there have been a few pieces in the press about people getting into trouble for drone use.

In October, a European football qualification match was abandoned after a drone carrying inflammatory language on a large tail was flown over the pitch. It’s appearance caused a scuffle between players that got so out of hand that the referee had to lead the players off and later abandon proceedings.

In what I might see as a copycat incident a week later, a man was arrested after a drone was seen flying over Manchester City’s stadium during a game. Read more about these events on the BBC.

This week reports abound of a near miss at Heathrow airport in London involving an unidentified drone. An Airbus carrying 180 people almost collided with the drone that is too small to appear on radar. Police are searching for the pilot. This article describes the event and goes on to explain flying rules in the UK for such machines. The owner of the drone will be in serious trouble when the police catch him, and could face fines of up to half a million pounds.

In a related incident police are investigating reports of drone flights over a nuclear power station. Once again in October but this time in France, police received reports of a series of drone flights over nuclear power stations. The flights were at night, and seem to have been coordinated, and this fact has set a few alarm bells ringing with the French authorities. Were they spies, terrorists, anti nuclear campaigners or just people having a laugh? Who knows? Read more here.

Drone use is becoming ever more common and the trend is bound to increase, but given the problems above this growth is certainly not unproblematic. In a previous post I wrote about privacy implications, and earlier this year Christopher wrote about Amazon’s possible drone delivery service. Find the links here.

On a scientific note NASA are developing a biodegradable drone. It is made from mushroom and cloned paper wasp spit, and the materials used are hailed as possibly offering a new substitute for plastic. If the machine crashes it simply biodegrades leaving no trace, so could be used in sensitive areas without fear of contamination.

Certainly one to look out for.

Sending People and Animals into Space

laika

I watched NASA TV all afternoon today. I wanted to see the launch of the new US Space Agency flagship Orion, but unfortunately technical issues led to it being postponed. They will (and I will) try again tomorrow.

Space Difficulties

This is an interesting launch for one major reason, it is the first test flight of a capsule that will carry people, possibly to Mars, but certainly into outer space. The test is going to send it way out beyond the orbiting space station (3600 miles), into an area that is much more inhospitable.

One issue that is different at that kind of distance is radiation. The radiation level is high, high enough to effect machines let alone humans, and so the test will measure how much the engineers have managed to insulate the capsule from this problem. Incidentally this problem is often cited as evidence that the US moon landings were faked, with critics saying that the astronauts would not have survived the radiation levels if they had actually gone there. But that is another post!

Another thing to be tested is its capacity to withstand the temperatures of re-entry in to the atmosphere. You might recall one of the Space Shuttle missions ending in disaster as it burnt up on re-entry due to faulty tiles on the underbelly.

Now I would like to see a rocket launch, but it is a completely different thing to see one with a capsule carrying people attached. I remember the golden days of space travel, when it was only animals that had the chance of orbit. (I don’t really remember them).

Animals or People?

It is after all a dangerous game going into space. This Wikipedia article lists all of the deaths involving space travel, both on the ground and in the air. 19 people have died during space flight, but another 11 have died in training, and if we think that only 533 people have been into space then the fatality rate is high.

So will they send animals in the capsule to test it out again? I doubt it, but alongside the 500 odd people in space we should not forget our animal friend heroes, some of whom gave their lives for this great mission.

Fruitflies, a pest sometimes and national heroes on other days. Fruitflies were after all the first animals sent into space, way back in 1947. In 1949 they sent a resus monkey up called Albert 2, although he died on re-entry. They did have some sensor data however so it ewas not all in vain. They are little remembered though, unlike Laika the dog. Laika was rescued from the streets of Moscow, trained, and sent on a one way mission into space. It is not known how long she lived, the capsule burned up on re-entry, and I am not sure why she was sent, but a heroic end to a flea ridden mut it was in November 1957. There she is in the photo above.

2 dogs did however make it back in one piece after a quick orbit. In 1960 Belka and Strelka made it back home, and I am sure received the welcome they deserved.

Then there was Ham, a chimpanzee. He was trained to interact with the vessel, pulling levers and feeding himself. He became a celebrity upon his return and there is even a documentary film available about his and his friends’ pioneering lives.

If you would like to know more about animals in space (I bet you can’t wait) check out this link.

I am looking forward to a launch tomorrow, with or without animal passengers.

On a final note follow this link to see a photo reportage about abandoned NASA facilities. The places that launched some of these great missions are now in ruins. Makes you think!

The ISS

The International Space Station is amazing. Humanity has a permanently manned space station.

You may think I’m saying that in every article of this series, and I probably am. But that’s because space and our accomplishments are quite frankly brilliant!

Mir

The International Space Station (or ISS) is not the first manned space station. The Russian space station Mir is widely considered the first successful long-term space station. Before the launch of the ISS, Mir was the largest satellite in orbit, and until 2010 when its record was surpassed by the ISS, Mir housed the longest continuous human presence in space; an impressive 10 years.

The Russians were leaders in space station technology, and without their expertise, I would argue the ISS would not be here today.

A Joint Venture

The International Space StationThe ISS is a joint space venture between Russia, the United States, the European Space Agency (the people who put Philae on a comet) Japan, Canada and Brazil.

The station was initially launched in in 1998 and has been continually manned since November 2000. Currently the station’s future is confirmed until 2020. It’s long-term future is to be determined by the relations between its key partners, the US and Russia.

The ISS is constantly being improved and upgraded, and is still being built. Amongst their most recent upgrades, includes the installation of a 3D printer. All the add-ons and upgrades are making the station heavier and heavier, and it now weighs more than 400 tonnes! But don’t worry, it isn’t going to fall from the sky any time soon.

The ISS can be seen from Earth, and if you have a pretty jazzy telescope, then you can view it in pretty remarkable detail. If you want to give it a go, check out NASA’s ISS spotters guide.

You can also track the ISS, and see exactly where above the Earth it is in real time. Check out this site which has a live view of what part of the planet the station is over. You may be surprised just how quickly it is moving!

Next Week

After the Thursday post last week and yesterdays site issues, I’m hoping that next Monday’s post will go without a hitch! See you then.

The Size of Space

I’m starting with a fact today; two actually.

FACT

According to astronomer Dr Peter Edwards, if our solar system was a grain of sand, then The Milky Way (our Galaxy) would be 1,000 times the size of Durham Cathedral.

FACT

According to NASA there are hundreds of billions of galaxies in our universe.

Need a more visual representation of that? Well luckily for you, the American Museum of Natural History have spent quite a long time developing a digital universe.

Somewhat mind boggling, isn’t it. Dr Edwards doesn’t think the human mind is really built to understand the enormity of the universe. I think I probably agree with him.

In 2012 the Hubble Space Telescope zoomed in on a seemingly empty area of space. This area of space could be covered up with just a single grain of sand if you were looking at it from Earth. Astronomers didn’t think they would discover much, but if you have a super duper space telescope, why not see what it can find?

This is what that seemingly empty bit of space actually looked like when Hubble zoomed in.

A Hubble Space Telescope picture of millions of galaxy clustersEvery single speck of light you can see is a galaxy. Yes the 100 or so huge ones in the foreground, but also the millions in the background.

Each of those galaxies contains billions of stars. Yes many of them look insignificantly small, but they are very very far away. So the well used fact that there are more stars in the universe than there are grains of sand on Earth is actually true. In fact there are many billions more stars in space than there are grains of sand on the Earth. Each star is in solar systems filled with matter – from specs of dust to moons and planets.

The title of this article suggests that I will try to quantify the size of space. This isn’t really possible, so all we can currently do is describe its size relative to other things. If I had to use one word to describe space, I think it would have to be enormous.

A key question surrounding space is: is it infinite?

That is an existential question which I doubt we will ever know the answer to, but never the less it is still an interesting question, which is worth considering.

The theory that the universe is a sphere – like the Earth – is a popular one, and I can understand the logic in this, if you keep going, eventually the universe will loop you back around to where you started. But then my problem with this theory is we can go beyond the Earth. We can travel around the Earth, but space travel proves that we can move in 3 dimensions, straight and sideways on Earth and then upwards into space. If you got to the very edge of the universe, what would happen if you went upwards? If there isn’t an upwards, what is there?

New Scientist states that from all current data, it seems that the known universe has a diameter of about 93 billion light years. That’s pretty big, but by no means infinite. So if this estimate is correct – which is ridiculously unlikely – what comes after that? A big wall with a no entry sign? Just empty space? Another universe? Who knows…

That’s Your Lot

See you next week for the next in the series.
