Elon Musk’s Starlink system in Ukraine

SpaceX’s “Starlink” satellites: This is what’s behind Elon Musk’s project

Conflicting reports about the Russian warship Moskva

There will be an edit button on Twitter soon, the company confirms

Has Elon Musk Bought Twitter?

The idea was inspired by the aggression of Russia. In order to design the tank, a defense consortium from Germany is contributing. Such a combination can only lead to a successful project.

Elon Musk Technology in Ukraine

During Russia’s war against Ukraine, Elon Musk’s technologies have already been a significant factor. Musk offered Ukraine the use of his satellite Internet system during the early days of Russian aggression. This proved valuable!

As a result of the Russian invasion of Ukraine, many countries have beefed up their military assets. Despite not being directly affected by Russian aggression, Germany has begun to significantly upgrade its military.

No official response has been received from Putin or anyone in the Russian government. Musk may pose a threat to Putin’s forces in other ways as well, so Moscow may find it difficult to ignore this.

SpaceX’s Starlink satellites are now helping Ukrainian military drones track Russian tanks and trucks. Specially fitted with thermal imaging cameras, the drones have anti-tank missiles. Russian vehicles can be detected at night when their crews are sleeping.

The current Russia and Ukraine crisis has thrown the world into turmoil. Although it is a classic Putin move, some are scared and others are determined to help the helpless. Elon Musk is one of them. Suddenly, he experienced a “eureka” moment to save Ukraine.

There will be an edit button on Twitter soon, the company confirms

Edit button on Twitter. The company says it is working on an edit button so users can change tweets after they are posted. The move follows a Twitter poll by Tesla boss Elon Musk asking his followers if they wanted the feature. People have been calling for an edit button for a long time, but there’s a concern about how it would work. Twitter said they are going to test it in the coming months.

Edit button on Twitter

In the coming months, Twitter will begin testing the feature with Twitter Blue subscribers, said the company said on Tuesday.

Sullivan, the company’s VP of consumer products, said the process of editing has been “the most requested Twitter feature for many years” on Tuesday.

The company has been exploring since last year how to build this feature “safely”.

A Poll conducted by Elon Musk on Twitter

Elon Musk is already keen to see the first major changes to Twitter. Musk has become the company’s largest shareholder, taking a 9.2% stake in the social network.

Elon Musk asked his 80 million followers if they would like to see a button added to the site to edit tweets after they are posted.

The “edit button” has been one of Twitter’s most requested features since the service’s launch in 2006, but its potential use has been criticized for opening up the possibility for users to change the meaning of their posts after they have been shared thousands of times.

In a question and answer session with Wired magazine in 2020, former Twitter CEO Jack Dorsey spoke clearly about adding this feature to the platform. “The answer is no.”

Even before Elon Musk joined its board, Twitter was working on an edit button.

It certainly looks like Tesla’s CEO is speeding up the process.

Musk makes real-life decisions based on Twitter polls, despite their notorious unreliability.

Earlier this year, he asked his 80 million followers whether he should sell 10% of his Tesla stock. A poll showed he should sell, and he did.

The chief executive of Twitter has taken Elon Musk’s poll seriously. “The consequences of this poll will be important. Please vote carefully,” Parag Agrawal said.

As a result of the poll, Twitter is likely to change its policy in this area.

A Look at How SpaceX Plans to Test 29 Raptor Engines

SpaceX is developing a massive methane engine called Raptor that will power its next-generation rocket, called Starship. So far, SpaceX has only performed a few pressure tests on Booster 4, their most complete Super Heavy booster. So, they will start by doing smaller static fires with just a few engines and then build up to the full 29. When Booster 4 lights up all 29 of its engines, it will produce a level of thrust 7 times greater than the Falcon 9. The only other rocket that comes close to this is the Soviet N1 rocket.

How SpaceX Will Test 29 Raptor Engines

It was a similar size to Starship and also featured a similar layout of 30 engines. Many of the failures were caused by explosive engines which led to a chain of other problems during launch. With much more advanced computer systems now, SpaceX will hopefully be able to shut down a failing engine before it turns into a grenade. This is a problem that SpaceX is hoping to solve with its Boca Chica facility.

But it’s not just the rocket itself that could cause problems during a static fire. The entire launch infrastructure surrounding the rocket plays a crucial role in keeping the rocket safe. Normally, launch pads use a flame diverter to deflect the intense exhaust away from the rocket and the launch pad. But SpaceX is taking a much riskier approach with Starship.

In the past, this has caused problems for SpaceX, with large chunks of concrete being thrown back up into the engine bay, completely destroying engines. In order to avoid this, SpaceX covers the concrete in an ablative coating called Martyte. Its main goal is to reduce the sound energy created by the engines, which can be extremely damaging to both the rocket and the launch pad. Another factor that SpaceX has to consider is the sheer amount of load on the vehicle when all 29 engines fire up.

The thrust puck at the bottom of the booster is designed to transfer all of the force from the engines onto the walls of the booster. This is something that SpaceX already does on both the Falcon 9 and Falcon Heavy rockets. On the Falcon 9, opposing engines are lit in pairs, 150 milliseconds apart, meaning the rocket reaches full power in just half a second. Part of the reason for having so many engines instead of just a few larger engines is redundancy.

If multiple engines shut down during a launch or landing, it won’t mean the rocket is destroyed, since the other engines can turn on or throttle up to compensate for the loss of thrust.

During a Starlink launch last year, a Merlin engine shut down during launch but the Falcon.

On the Falcon 9, only 3 engines are able to perform the landing burn, so there is nothing they can do if one fails to light. But since Super Heavy has way more engines than the Falcon 9, it will give it a much wider throttle range, allowing it to hover. No matter what happens during the first full static fire of Super Heavy, it’s guaranteed to be extremely exciting. Either way, it’s amazing to think about all of the incredible engineering that has gone into making not just the most advanced rocket engine ever made but also the enormous structures that sit on top of them.

Raptor engine development

SpaceX has developed and manufactured the Raptor family of full-flow, staged-combustion-cycle rocket engines for its Starship project. As opposed to the previously used kerolox (RP-1 kerosene and LOX) in the Merlin and Kestrel engines, “methalox” (“cryogenic liquid methane and LOX”) will power the new engine. Compared to SpaceX’s Merlin 1D engine used for Falcon 9 and Falcon Heavy, the Raptor engine has more than twice the thrust.

In the Starship system, Raptors are used both in the super-heavy-lift Super Heavy booster and in the spacecraft that is launched from Earth as the second stage and in LEO as an independent spacecraft. SpaceX’s Starship is planned for many applications, including Earth-orbit satellite delivery, deployment of the Starlink satellite constellation, lunar exploration, and colonization of Mars.

US Air Force awarded SpaceX a US$33.6 million contract to develop a prototype of its reusable Raptor engine for use on Falcon 9 and Falcon Heavy launch vehicles. SpaceX had to match with US$67.3 million in funding. In 2018, the contract work was supposed to be finished at Stennis Space Center and Los Angeles Air Force Base.

How Does Tesla Test Their Cars

The company claims that its electric cars are the “Safest cars in the world” but what evidence does Tesla, and CEO Elon Musk, have to back up that bold claim? In this article we will look at various aspects of testing, but ultimately, they all boil down to two core principles: safety, and reliability.

How Tesla Vehicles Are Tested

Video: Tesla Model 3 crash test.

The company emphasises three important features that make its cars so safe. The features are a combination of:

  1. Active safety technology
  2. Passive safety technology
  3. Automated driver assistance systems

All of which are put through rigorous testing to ensure ultimate performance.

Put simply, active safety refers to a set of features that step in to help prevent an accident in the first place, such as:

  • Electronic stability control
  • Electronic brake-force distribution
Tesla car test active technology.
Tesla test active technology based on real-world scenarios.

Passive safety comes into play in the event of a collision, and includes things like safe seats and headrests, airbags, child seat mounting points and seatbelt pretensioners.

Automated driver assistance systems are a little harder to define, because they tread along the line that separates this category from active safety technology.

In general, these can include lane and blind spot monitoring systems, adaptive cruise control, and in the case of Tesla, evasive steering.

All three of its mainstream cars:

  1. The Model S
  2. Model X
  3. Model 3

Each Model achieved the lowest possible probability of injury of any car when tested by the ‘US New Car Assessment Program,’ and after crossing the pond, achieved similarly impressive five-star ratings at the notoriously harsh ‘Euro NCAP‘ testing.

These tests see multiple production cars thrown at obstacles at different angles and speeds, filled with dummies representing men, women and children as passengers.

The Model 3 crash test score

The Model 3 achieved one of the highest scores in the increasingly stringent European tests:

  • 96% rating for adult occupant safety
  • 86% for child occupant safety
  • 74% for vulnerable road users
  • and 94% for its safety assist systems

For reference, a Volvo S60, a similarly sized saloon car built by a company that prides itself on its safety, achieved the following scores. The test scores shows just how advanced Tesla’s safety technology can be; the ‘safety assist systems’ in particular.

Most electric cars are inherently rigid, benefitting from large crumple zones and a low centre of gravity, thanks to the strong battery packs that are generally located under the cabin.

Applying mathematics and physics to the design of its cars is Tesla’s first step to engineering and testing the safest cars on the market.

Stage two involves real-world testing of Tesla cars

How does Tesla test their cars, stage 2.
How does Tesla test their cars, stage 2.

While most manufacturers take a sample of one vehicle in every couple of thousand produced to test, we’re told that Tesla takes a lot more.

The team is headed by Jeff Hickethier, who has been working in the automotive industry for decades.

When he’s not testing the cars, he’s sitting in the passenger seat instructing the next generation of testers.

The primary facility is located adjacent to the Fremont factory in California; the track dates back to the 1980s when the factory was originally jointly owned by General Motors and Toyota. The track has been perfected over the years to provide the most accurate scenarios for the best results.

Hickethier teaches his team to focus on every little thing that the average consumer wouldn’t even notice.

This can include checking brakes and wheel alignment through feedback from the pedal and steering wheel.

The track includes lengths of harsh bumps that are designed to:

  • Rattle the cars
  • Highlighting loose fittings and fixtures
  • Long, fast straights for high-speed
  • Acceleration testing

Some cars then make their way northbound, until they reach the emptiness of Alaska.

Near Delta Junction is a dedicated testing ground, made up of perfectly manicured snowy and icy surfaces, as well as snowy handling courses, iced hills and a suitably large skidpad. Tesla shares the facility with the military, which tests its tanks in the extreme weather.

It’s not just on and off-road stability that Tesla tests

Tesla car test off-road assist.
Can you take a Tesla off-roading?

The heating, ventilation and air conditioning system is fine tuned here to help it perform more efficiently in colder climates. The battery thermal and power management is tuned as well.

The best off-roaders use locking or limited-slip differentials for maximum off-road grip, which allows each wheel to deliver the right amount of power.

Tesla, on the other hand, uses an open differential which means both the wheels on any given axle spin at the same rate.

Put simply, the front left wheel may be gripping sufficiently while the front right wheel may be spinning wildly in a failed effort to get traction.

Rather than fit its cars with the more expensive and sophisticated solution that most people would not even require 99% of the time, the company opted for a cheaper alternative that it calls an e-differential, which applies the brakes to individual wheels to prevent unnecessary spinning.

Clever, but not unique; the likes of BMW and Mercedes have been using this sort of system for years.

The final stage of testing may not be what you expect – by this point, the cars are on the roads, in the hands of the general public.

Every single Tesla that rolls off the production line since the early Model S is digitally connected, full-time.

Over one billion miles in Autopilot mode alone have been logged and recorded so far, helping to develop active technology based on real-world scenarios.

Thanks to this, unpredictable events like other drivers’ errors and unexpected fires have led to new developments.

Now, for example, fires in the battery get isolated to prevent spreading, while heat is ventilated away from the cabin.

No other manufacturer is doing anything like Tesla

Which puts the electric vehicle manufacturer (Tesla) paces ahead of competition.

Thanks to this extensive and revolutionary testing model, beating the safety scores of any Tesla Model has become almost impossible.

Whether you believe the marketing material or not, it’s clear that Tesla is dedicated to extensive testing, ensuring that it creates the safest possible product.

Do you know of any other manufacturers that go to such extremes to test their cars? Let us know in the comments below.

SpaceX’s “Starlink” satellites: This is what’s behind Elon Musk’s project

The “Starlink” project by SpaceX and Elon Musk aims to make high-speed Internet available everywhere. Many satellites are required for this – that is a source of criticism.

  • The private space company SpaceX of Elon Musk wants fast Internet from space
  • For this purpose, thousands of satellites are to be brought into orbit
  • Astronomers have criticized the “Starlink” project from the start

The private space company SpaceX is not only causing a stir with its recycling rockets “Falcon 9” or the fact that it is the first private company to transport astronauts into space. Even the “StarLink” project of SpaceX is hotly debated – among other things because the result can be seen already in the skylights, which consist of satellites, pulling visible across the dark sky.

“Starlink”: this name stands for SpaceX’s ambitious project, whose founder is the billionaire and Tesla boss Elon Musk. SpaceX uses its recycling rockets “Falcon 9” not only to transport the manned space capsule “Crew Dragon”, but also to send countless satellites into space, which in the future should enable fast Internet from space in all corners of the world. “Starlink” will bring high-speed Internet to places “where Internet access was unreliable, expensive, or unavailable,” the company said.

To this end, thousands of satellites are to be transported into earth orbits in the future. A global network will be set up there to provide Internet access – in 2020 in the USA and Canada and as early as 2021 worldwide.

Three expansion stages are planned for the “Starlink” network:

  • First expansion stage: Almost 1600 “Starlink” satellites are to orbit the Earth at an altitude of 550 kilometers
  • Second expansion stage: About 2800 “Starlink” satellites are to orbit the Earth at an additional altitude of 1100 to 1325 kilometers
  • Third expansion stage: Up to 7500 “Starlink” satellites are to orbit the Earth at an additional altitude of 340 kilometers in a polar orbit

In total, SpaceX has been granted temporary licenses until 2027 for the launch of up to 11,927 “Starlink” satellites. Also, SpaceX applied for the launch of a further 30,000 “Starlink” satellites to orbit the Earth at altitudes of 330 to 580 kilometers.

The “Starlink” satellites of SpaceX are visible in the night sky. In this case, as a tracer, because the image was exposed for a long time.

This global satellite network aims to provide high-speed Internet with up to 1 GB/s for every user on Earth. As soon as about 1000 “Starlink” satellites are in space, the “Starlink” project should be “economically justifiable,” according to SpaceX boss Elon Musk. “If we put significantly more satellites into orbit, that’s an excellent thing, which means there will be a great demand for them,” Musk continues.

Each “Starlink” satellite weighs about 260 kilograms and is very flat. The satellites can be stacked for launch in the “Falcon 9” rocket. So far, 60 “Starlink” satellites are sent into space per launch. After seven launches, 420 “Starlink” satellites are in orbit around the Earth (as of April 23, 2020).

The first two prototypes of the “Starlink” satellites were already sent into space in February 2018. The first launch with 60 satellites took place in May 2019 – and immediately triggered a great controversy. In the days following the launch, the satellites were very bright and visible in the evening sky. A satellite tracker from the Netherlands had filmed satellites’ widely visible train in the sky and started a discussion with his video: Are the Starlink satellites disturbing the night sky? Is the night sky even being “littered”?

On Twitter, SpaceX founder Elon Musk quickly explained that the goal was “possibly to help billions of economically disadvantaged people,” but the outcry could not be contained. The International Astronomical Union (IAU) expressed “concern about these satellite constellations”. It is concerned about “the principle of a dark and radio silent sky” and “resource for all mankind and also for the protection of nocturnal animals”.

Many astronomers complained publicly. On Twitter, astronomers keep coming back with examples of how the “Starlink” satellites affect their work. In November 2019, Clarae Martínez-Vázquez, who works at the Cerro Tololo Inter-American Observatory (CTIO) in Chile, used an image to illustrate how the satellites thwart their work: As many as 19 “Starlink” satellites would have interfered with a long-term recording, “the train of Starlink satellites lasted longer than five minutes,” she wrote on Twitter, adding: “Pretty depressing… That’s not cool!”

Meanwhile, the IAU and the American Astronomical Society (AAS) are working with astronomers on the problem, and talks with SpaceX have taken place, according to IAU. The company launched a “Starlink” satellite in January 2020, which has a different coating and has been given the nickname “DarkSat”. Its surface may reflect less sunlight. In the meantime, SpaceX has announced the measures it intends to take to darken the “Starlink” satellites.

As the IAU further reports, SpaceX is also working on software that will allow observatories to bypass “Starlink” satellites by writing appropriate programs.

But is this the solution to the “Starlink” problem? The experts are not only bothered by the sunlight that is reflected by the satellites and can disturb the sensitive telescopes. They are also concerned about the effects that the radio signals from the “Starlink” satellites could have on astronomical observations with radio telescopes.

Fast Internet from space lets number of satellites shoot up

Although Elon Musk emphasized on Twitter some time ago that he would make sure “that Starlink does not affect discoveries in astronomy”, he also said that he would not use Starlink for any other purpose. But the scene is still skeptical. After all, SpaceX is not the only company with plans for a global satellite constellation that will provide fast Internet from space. Amazon is also pursuing similar goals. Competitor OneWeb had already launched the first satellites, but had to file for bankruptcy in the wake of the Corona crisis.

SpaceX, on the other hand, is continuing unwaveringly in the Corona crisis. There are now 420 “Starlink” satellites orbiting the Earth and the mission is expected to continue. Critics of the mega-satellite constellations’ plan are particularly disturbed because the number of active satellites in orbit is being increased many times over. In September 2019, 2218 active satellites were orbiting the Earth. Also, there are countless discarded satellites and space debris, down to the smallest particles.

Since the launch of the first satellite “Sputnik 1” in 1957, more than 8500 satellites have been launched. The plans of SpaceX alone would increase this number significantly within a short time. If SpaceX continues to make progress with its “Starlink” project as planned, it could happen in the future that more satellites will be visible in the night sky for a short time than you can see stars with the naked eye. Under perfect observation conditions, this is a maximum of 3000 – in light-polluted cities, even less than 100.
