Here are a few awesome things that it would be nice to see for SpaceX launches.
Follow the second stage SpaceX have a responsible attitude to space debris mitigation and they de-orbit the second stage after deployment. It would be awesome to follow the second stage into the atmosphere. We do know that the second stage has a camera on board but we don’t know if it has the battery capacity or downlink capability to transmit as it comes back down towards the Indian Ocean.
See inside the tank Every now and again, SpaceX give us an accidental view inside either the fuel or oxidizer tank. It looks amazing and it would be great to see a longer view of that view, maybe even while the engines are burning!
Follow the Fairing We don’t know what if any telemetry capabilities the two fairing halves have, but following them down would be an amazing ride!
Stage 1 Telemetry It would be pretty cool to have a view of the stage 1 telemetry after separation rather than following stage 2. Stage 1 goes pretty high and comes in pretty fast, it would be great to follow it all the way down one day
It seems that we will all have low latency, high bandwidth internet soon, regardless of where we are on the earth, all courtesy of SpaceX and Starlink. It seemed like a good idea at the time to make a Kerbal representation of the constellation just for shiggles over the xmas lockdown.
Step 1 – Design the bird Rather than start from scratch, I had a search around (similar to a customer looking for a satellite bus format) and found this video from Gameplay review UK. After some messing about we end up with a lovely flatsat layout with a gigantor array and xenon power.
Our bird is designed flat so we can launch a stack of them. we base it on the OKTO2 and add mechjeb2 for additional control plus a reaction wheel for in service orientation (our normal orientation is radial out).
Launch weight is not too much of an issue so we have a full xenon tank and around 1200 delta v – enough for many years of faithful service and orbit raising.
We simulate the Starlink service with a pair of antennas – the Communotron 16-S for C&C and the folding SG-5 for the user internet traffic.
We put a Z100 battery pack on board so that small DV adjustments (<10 m/s) can be made even on the dark side of Kerbin. A couple of flat solar panels each side of the sat give us emergency power to deploy the gigantor.
Considerable tweaking is needed to get the COG aligned with the xenon engine.
Step 2 – Testing the bird I built a SSTO rocket and fixed one satellite to it – we’ll call this the TinTinA launch. Launched to a nice low 100km orbit, the satellite works great – it’s controllable and maintains power throughout it’s orbit and has enough electricity for small DV changes. we have just enough DV in the booster to deorbit and our orbital debris is zero.
Step 3 – Orbital Parameters Starlink orbits at 350km and at an inclination of 53°. Our constellation will use identical parameters even though that’s a much higher relative orbit. Looking at the offsets around Kerbin, we need to launch at around 7 minutes 30 offsets – this gives us about 49 separate orbital planes to fill, or around 2500 separate satellites (EEK)!
Step 4 – Extended orbital test programme Extending the TinTinA launch, we send up 48 further single sat launches to test the concept and test the coverage. Again, we set these launches low, but to the correct inclination. This is successful and after the testing is complete, all test artefacts are deorbited.
Step 5 – Testing the stack The first stack design is built and tested as a two stage to orbit dispenser. We release all the sats at once and deorbit the dispenser. This first attempt of 24 birds is messy – using the SpaceX technique of allowing the set to jostle a bit results in a few damaged birds – typically the gigantor array. it takes quite a while to deorbit the failed satellites using only the tiny fixed panel. Another problem with the all-at-once dispenser is that the satellites disperse too unevenly. Because they have to be individually positioned, they drift a long way in the orbit it takes to position each one.
Deorbiting the failed birds gives us a chance to test that they burn up completely in the atmosphere. They don’t, but it’s a bit late to do anything about this. As we have lot’s of delta V, we’ll try to controlled deorbit them into the ocean. Luckily Kerbin seems to be very sparsely populated.
The stack is redesigned slightly to release them individually and we try again. Now we have a stack of 38 on a two stage configuration.
It turns out that this is still a very messy configuration – the dispenser is aligned to prograde prior to sat deployment and then the idea is that the satellite can boost away from the 330 deployment orbit to the 350km operational orbit, but the stack is upside down and so there is considerable delay while the bird clears the stack far enough to invert it and deploy the antenna and solar array.
There is also a problem with the supports: many support struts were needed to prevent the stack flopping around and these were not all applied from the dispenser to the satellite. On separation, any bird with the strut base is unstable under thrust.
Step 6 – Testing one orbital plane Testing the deployment of one entire orbital plane is hard work – we are working with a version one stack and so they are all upside down. Some of them have the detritus from the support struts and this means that they don’t produce thrust through the CoG. It takes about 8 hours (real time!) to deploy and we hit another snag: The last two birds are not on separation rigs and so are permanently attached to the dispenser. Another redesign!
Deployment process Checklists for the win! It’s really easy to miss a step in the deployment for each satellite and as there will eventually be 2500 of them, probably important for a repeatable list.
Launch Launch dispenser to 330km Circularize Check and adjust plane and offset from Tune Apo and Peri to 330 exactly
Planning a train The deployment process for each train needs careful timing and coordination – satellite spacing in the plane is determined by timed release of each sat. Once you have the apoapsis and periapsis well sorted and the inclination is solid, you need to warp to ‘dawn’ from the dispenser point of view: You are going to release the bird, boost it’s apoapsis and then circularize half an orbit later when it reaches apoapsis. you want to make sure bot of these happen in sunlight. After circularizing, you will flip back to the dispenser and repeat the exercise and so it should all be happening in daylight. If you screw this up, the whole train will be launched at night and the power budget is very tight!
The UT between each deployment is 30 minutes. That gives you time to release, align, raise Apo, wait for apo, circularize, rinse and repeat. Just. Every few launches, you will want to adjust the dispenser apoapsis back to 330 – those constant prograde sat deployments cause the dispenser to slow down!
Hints, tricks and tips Creative use of the different ship type icons can help finds ways to declutter the screen *ahem* when in Tracking station and Map view. Perhaps use one for the dispenser, one for birds that have been deployed but not fine tuned, another for fine tuned, Another for on-orbit spares and another for the head of each train.
Name each satellite according to the launch, the plane and a unique number. I use starlink 430-33 where 430 is the launch time UT and 33 is the position in the train. I add ‘HEAD’ to the reference bird in each train and give it a different icon.

After circularization complete orient ‘radial out’ Switch back to the stack and repeat.
Post Deployment Dispenser decommissioning The empty dispenser is now useless. If you have not needed all the birds, keep the dispenser on orbit to keep them together. If keeping the dispenser, probably raise it’s orbit to that of the main plane for collision mitigation.
To deorbit it, you have choices. If you included chutes, you may want to go for a land return at KSC. It does have enough DV for alignment but not a powered landing. The dispenser is unlikely to survive re-entry unless designed quite carefully – it’s as aerodynamic as a house brick. Conduct your own risk assessment! Otherwise use Mechjeb and pick a nice uninhabited spot in the ocean. Bear in mind that a return to KSC from a 53° inclination may require a long warp.
You could of course boost the dispenser into deep space or go for a graveyard orbit. You may have the DV for either of these, but they are not very SpaceX!
Deployment Fine Tuning Change the engine power to 5% Orient prograde or retrograde as required Warp to apoapsis -10 seconds or periapsis as required Tweak orbit to 350km x 350km exactly. A couple of meters is acceptable. you may decide, based on your own collision avoidance measures to put each train at a slight different height, say 100 meters separation on each orbital plane. This would be the right time to chose that number and start tweaking. Deactivate unused equipment (engine) to prevent any power drains and accidents. You may be able to deactivate mechjeb and other systems.
Finally, the small-handed orange wank-hammer is out. The electoral college votes have been cast and he is out baby, out.

If you’re a man, you’re likely aware that you’re expected to pay a fair amount of money to get a vasectomy. But if you’re a woman, you might not be aware that you’re expected to pay — and a lot more — for an IUD.
In this post, we’ll take a look at the costs of different types of contraception. We’ll also talk about the differences in cost between the types of contraception available for people of different ages and incomes.
The Cost of Contraception
Before you can get pregnant, you have to get rid of the sperm cells in your body. To do that, you have to take a pill.
There are three types of birth control pills: the hormonal option, the copper-based option, and the copper IUD. Each of these has its own advantages and disadvantages.
For example, the hormonal birth control pill, which is used by about 10 percent of all women, is considered to be one of the most effective forms of birth control. It’s the only type of birth control that’s effective for up to 20 years after you stop taking it.
Also, the hormonal birth control pill has the lowest chance of causing what’s called breakthrough bleeding, when the estrogen levels in your body start to rise. For this reason, the pill is considered the most effective type of birth control.
One of the enduring mysteries of the Battle of Fredericksburg is why the Union Army, led by Gen. George Meade, did not commit a single casualty in the battle of October 1, 1862. The battle, which killed an estimated 300 Union soldiers, was fought on the second day of the Battle of Gettysburg, which was fought to a disastrous conclusion.
The Battle of Fredericksburg was the last battle of the Civil War, and the last major battle fought in the Carolinas. After the Union Army’s capture of the Confederate capital of Richmond the following year, Meade ordered the Army of the Potomac to begin the retreat from the battlefield. The Confederate Army was commanded by Gen. Jubal Early’s Army of Northern Virginia.
Early’s army, which had a large contingent of African American troops under Maj. Gen. Joseph E. Johnston, was the largest adversary of Meade’s Army of the Potomac. Early’s forces were reorganized as the Confederate States of America in 1864 to create the Confederate States of America.
On October 1, 1862, Early’s army attacked the Union Army’s positions at Fredericksburg with a force of nearly 3,000 men. Early’s army was led by General John C. Breckenridge. Breckenridge was also the commander of the Union forces at Fort Donelson.
While the Union Army was within a few hundred yards of the Confederate position at Fredericksburg, Breckenridge ordered Major General John P. Gordon’s cavalry to halt and take up defensive positions at a point approximately two miles away. Breckenridge ordered the Union cavalry to attack at dawn and break through Early’s line. The Union cavalry attacked at 6:30 a.m., and the Union infantry attacked at 7 a.m.
Like the Union Army, Early’s Army of Northern Virginia was composed primarily of African Americans. The Union Army was commanded by Maj. Gen. Jubal Early’s Army of Northern Virginia. Early was African American, and drew his troops from the state of Maryland.
Early’s army was led by Maj. Gen. John P. Gordon, who was also African American.
The Union Army’s attack was a flanking maneuver. The Union cavalry attacked from the rear, overrunning Early’s infantry in the process. Early’s cavalry charged the Union infantry, and the Union infantry was forced to retreat to the rear.
One of Early’s officers, Maj. Gen. John Logan, was killed in the initial attack. Logan was Black. The Union Army’s first casualty was Maj. Gen. Horatio Gates, who was killed at Fredericksburg in the initial attack. On the second day of the battle, Maj. Gen. John G. Meigs was killed when his horse was shot. On the third day, Maj. Gen. John Buford was killed in the fight.
In the battle of Fredericksburg, General Jubal Early’s Army of Northern Virginia lost more than 1,000 men, including more than 500 killed. Early’s army lost more men than any other army in the entire war in the Battle of Fredericksburg.
The Confederate Army’s second-last casualty was Maj. Gen. Jubal Early’s Army of Northern Virginia.
The South Carolina Historical Society describes the Union Army’s overall performance in the Battle of Fredericksburg in a pamphlet, The Battle of Fredericksburg. In the pamphlet, the Southern Historical Society of South Carolina describes the Union Army’s overall performance in the Battle of Fredericksburg as lackluster.
At an auction house near London’s Chelsea Football Club team dressing room, U.S. online retailer Amazon.com Inc is preparing to start selling a home-built robot called “Lara,” based on a smart home platform developed at the University of Westminster.
Amazon, whose self-declared goal is to provide products for anyone regardless of their skill or means of payment, is investing hundreds of millions of pounds in so-called “E2E” (everything2ede) technology projects, which aim to bring the internet of things to more homes and make a broad range of goods – from food items to medical devices – wearable.
But selling kits from a computer game at a fancy auction house will push LARA into a much wider global market, by giving it an emotional hook that technology companies can use to hook customers – a crucial step in luring them away from traditional retailers.
The U.S. firm, which is focused on growing the market for its home-grown products in Britain, will also send one of its senior vice-presidents for research and development to London on Friday to show off how its technology works, two employees said.
The device is the brain behind a virtual smart home home where shoppers can control key parts of the appliances and devices to match their personalities and lifestyle. The self-styled “Lara” is available for pre-order from Amazon and is expected to ship in May.
It is the latest example of how U.S. technology companies have found business, or come up with alternatives to the traditional electronics outlets. Apple Inc has used an online subscription service to sell customers its latest products, while Samsung Electronics Co’s Galaxy S8 phones are being sold directly by the firm and not only online, as was previously the norm. Twitter Inc is also looking into bringing cheaper advertising to home-grown firms.
Amazon said it was focusing of LARA in the United States because of Britain’s regulatory environment in which it did not have to register itself as a self-employed seller with the UK’s General Data Protection Regulation (GDPR).
“We have a strategy for future growth, which always includes having a more strategic relationship with our platform,” said Ashish Jha, who is heading up Amazon’s new E2E strategy.
If war takes place, there is almost certain to be an air campaign. “It was only a question of time,” he said.
The two wars that Churchill predicted and was told by his confidential assistant after the German blitzkrieg of 1941 – Spain and France – failed.
The former prime minister gave little sign of how he would judge Donald Trump on Sunday, saying the US president-elect’s policies were yet to be put in place.
His concerns about Trump’s stated support for Ukraine’s president, Petro Poroshenko, are well known.
In the wake of Poroshenko’s January 2015 visit to a US military base, during which he was photographed with Trump advisers, Churchill made the claim that “the whole process is becoming confusing as to whether President Trump intends to follow up on his promise to take Ukraine out of Russia’s sphere of influence”.
“On January 21st the world will know whether Donald Trump will turn out to be a President for Germany or for Europe,” said Churchill.
• This article was amended on 9 January 2017. An earlier version referred to Donald Trump’s alleged offer to sell Ukrainian assets to the Kremlin while Poroshenko was visiting the US, not a promise of his support to Ukraine’s president.

With our Brexit ‘Oven Ready’ deal eaten by the dog, we have exited the EU and the almost equivalent to no deal brexit is only a few months away at the end of a transition period.
Transition period in this context equals the European negotiators basically saying over and over again “Are you sure this is what you want, are you REALLY sure because it sounds like madness to us”, and the UK negotiators shouting “LALALALALA”.
Anyway after the end of December 2020, along with food and energy, it is likely that insults and expletives will be stretched to breaking point. “Wheres the fucking food” and “Turn the fucking lights back on” will wear thin after a few months.
To this end, in advance of the transition period ending and the return of food stamps and blackouts, TurboTas has made for you an insult generator and a rude word portmanteau generator to start you off when you desperately need food, insults, expletives and water.
Be aware that after December 2020, this service will be very stretched, so you are advised to start saving up insults and expletives now along with rice, pasta and drinking water.
But don’t fear: the government has arranged for Financial Services to be in extra supply, so expect a delicious nutritious menu of pensions, insurance, credit and bank charges after December. Om nom nom or bon apetito if you are posh.
The insult generator is here and it generates very rude words. You have every right to be offended. If you want to play with the options, you could try ?help and turn on very very rude words and maybe try insult specific people.
The Portmanteau generator is here and also generates pretty rude words. The Portmanteau generator can help you come up with expletives. As with the insult generator, you could try adding ?help.
