I wonder if they’re also thinking about the future of suborbital transport? It seems distant to me, but it might play into the investment if they think this could be the Heathrow of suborbital transit in the future.
Possibly, Heathrow is pretty crowded, but somewhere within half an hour of London yes. A site on HS2, preferably in the most NIMBYest area, would be good.
For the low price of only $80,000, you can launch your own 1U cubesat with Rocket Lab [1]. For that price, you can launch a 10x10x10cm satellite, with a maximum weight of 1.3 kg, into a 500 km sun synchronous orbit.
Depends on the orbit it's in. If it's high enough, it will last long past your death. Whether it keeps working that long, probably not. Radiation damage accumulates reasonably rapidly and most cubesats don't live more than a few years, if that.
It is actually relatively accessible compared to the other two proposed spaceport sites, which are both on relatively remote islands: Unst on the Shetland Islands, and North Uist in the Outer Hebrides Islands[0].
Can't find a reference now, but apparently there's a "weather hole" over the area that gives it unusually high number of clear days. Related to the North Atlantic Current.
It's also handy for satellites constructed in Glasgow by ClydeSpace and others: https://www.bbc.co.uk/news/38804310
"In the last two years Glasgow has built more satellites than any other city in Europe".
> The UK Space Agency said the site in Sutherland was chosen as it is the best place in the UK to reach highly sought-after satellite orbits with vertically launched rockets.
Does anyone know what they mean by this? Usually rocket launch sites try to be as close to the equator as possible so why did they pick such a northerly location this time?
If you are going for a polar orbit (ie. circling from one pole to the other), any initial speed you pick up from the rotation of the earth will need to be cancelled out by burning fuel.
So the further north (or south) you go, the lower that speed is (since you are closer to the rotation axis).
If you’re going for an equatorial orbit, that initial speed is helping you, so you maximise it by launching as far away from the axis as possible (ie. somewhere close to the equator).
Svalbard is a bit tricky - while it is part of Norway (which itself is part of the ESA), it has military restrictions, and other countries can operate commercially from there.
There is a (suborbital) rocket launch facility there to study aurora etc, but it's limited to 4 launches per year.
Greenland could be a good site -- I believe they are still a member of ESA through Denmark, so Qaanaaq would be a great place for polar launches, weather and access permitting.
I don‘t know why nobody is mentioning it, but Esrange[1] in Kiruna is an active European launch site, arguably far more North than Sutherland. Even though launcher activities seem to be limited to sounding/sub-orbital rockets at the moment, I don‘t see a reason why they should be restricted to it.
Sun-Synchronous orbits. Earth observing satellites like them, they're good when launched from high altitude, and a lot of the newspace smallsat market is in earth-obs with modern optics and processing.
A sun-sync orbit keeps the satellite in the sun (out of Earth's shadow) and typically peels a whole pass of the planet every few days, IIRC.
This could be a mega boon to the UK as micro satellites are set to kick off in a big way. Uist and Shetland are terrible locations though - even Sutherland is a ball-ache to get to.
Everyone should cool their jets though, the SNP will make a balls up of this. They only have one goal, which is independence. There isn't a single competent SNP MSP.
They took away the bridge tolls to help them win votes during election time and then had to borrow money to pay for a new bridge while the old one disintegrated due to lack of maintenance funding.
Do these morons sound like they can handle a spaceport?
How anyone can look/listen to Nicola Sturgeon and be filled with confidence makes me shudder.

I'd expect the east of the UK to be better for both access and available launch dates. Perhaps air traffic corridors are a problem.
Pretty sure if your satellite doesn't fit on the back of a lorry you're going to have a hard time launching it from anywhere. What does this even mean

Here's a reference that's totally on point:
http://mstl.atl.calpoly.edu/~bklofas/Presentations/Developer...
"An Evaluation of CubeSat Orbital Decay" - everything you wanted to know (and more!) about the topic.
You could fit that kind of payload in the boot of your car.

Rocket Lab are only partially owned by Lockheed Martin.

(also Polar orbits, but there are fewer of those)

Schools, hospitals, roads and just about anything and everything the SNP has touched over the last 10 years has suffered. For example look at the new bridge over the Fourth - http://www.heraldscotland.com/news/homenews/14307424.Reveale...
