Today, it’s not an easy task to find a person who lives completely out of touch with the modern world. Information inevitably reaches us in one way or another, whether it’s television, newspapers, radio, the Internet or word of mouth. Above all else, it’s almost impossible to avoid news about recent man-made disasters.
Despite the development of modern technology, alarm and security systems, ships continue to collide with each other, submarines sink, planes crash, trains go off the rails, cars go out of control and turn over. This is the harsh truth that can’t be denied.
Obviously, most of these disasters happen due to human error or the so-called ‘human factor’. However, the fact is that the operation of any vehicle is inevitably associated with two impeding factors: inertia and mass. Some disasters could’ve been completely avoided if the pilot or driver had the right tool to quickly stop the vehicle or change its path of motion to avoid the crash.
Just imagine, that instead of crashing into a bridge, beach or another ship, it would’ve been possible to triple the turning rate of the ship and avoid the disaster by doing so, or at least minimize the damage taken. This is particularly important for huge ocean liners. After all, these small floating cities carry the most expensive cargo in the world, namely human lives.
Happy to inform you, that now there is such a tool!
Through joint efforts of the Russian and German engineers, we have developed a unique system, now known as “Gecsotor”. The system is aimed at improving the stability of heavy objects with a large inertial mass. The system has already made waves in the global scientific and technological community.
What are the advantages of the “Gecsotor” system?
An innovative control system;
Compatibility with both large objects and mechanisms, and smaller vehicles, such as motorcycles;
Ability to easily update old vehicle fleets, such as aircraft fleets, in order to achieve safer operation of such vehicles.
For road transport:
Improvement of road-holding ability for trucks and light motor vehicles;
Better vehicle handling during turns;
No turn-overs or skidding on icy roads.
For the water and underwater transports:
Tilting and turbulence decrease during storms;
Exclusion of the possibility of turn-over;
Increased maneuverability during the emergency;
Ability to navigate in ports without the help of towers.
For aircraft:
High flight safety in harsh climatic conditions;
Increased stability during takeoff and landing, decreased turbulence;
Lower airstrip length requirements;
Exclusion of the possibility of turn-over in any weather patterns;
Increased stability and torque compensation during aircraft nosing-up, tilting, and other emergency conditions.
On top of that, the “Gecsotor” system allows to change the path of motion without the use of the steering wheel, ailerons, engines with adjustable thrust vector and is a perfect choice for hypersonic flight.
The system drastically increases the reliability of aircraft with vertical takeoff and landing: convertiplanes, helicopters, drones;
Addition of the “Gecsotor” system to UAVs would provide the means to develop completely new devices, capable of withstanding seemingly impossible load and acceleration while being able to instantly change the path of motion.
The system has a wide range of applications in the space industry:
Optimization of satellite orbital positions;
Increased maneuverability of satellite stations;
Better launch vehicle control during the penetration of dense atmosphere layers;
Ability to lock the position of the object during coupling;
Giving space debris the desired direction of movement to burn it in the atmosphere;
Management and stabilization of used launch-vehicle stages or reusable launch-vehicles without using rocket fuel.
The invention is based on the interaction of the power systems and the vehicle body by means of storage, preservation, and subsequent use of the kinetic energy of the coupled flywheels in combination with the gyroscopic action. The system itself acts as a lever that allows the pilot to perform the necessary actions: rotation, locking position, and torque compensation regardless of environmental conditions and the coordinate system used.
The “Gecsotor” system opens up new ways to design and manufacture modern aircraft, road and water transport, as well as spacecraft. The high standards of safety and reliability of the “Gecsotor” system will significantly reduce the number of emergencies and save thousands of lives!

SpaceX has moved its plans for the first ever commercial launch using the Falcon Heavy rocket to Wednesday, 10 April at the earliest, provided the weather improves.

The Falcon Heavy will carry the Arabsat-6A satellite owned by Arabsat and the King Abdulaziz City for Science and Technology. The launch will be SpaceX's fourth, and the first of two such Falcon Heavy launches in 2019.

While the launch was initially planned for 9 April, weather on the day wasn't conducive for the launch, which has now been moved to 10 April at 10.35 pm GMT (11 April 4.05 am IST).

"Now targeting Falcon Heavy launch of Arabsat-6A on Wednesday, April 10 – weather forecast improves to 80% favorable," SpaceX tweeted in an update on 9 April.

The launch will take place from the historic Pad 39A at NASA's Kennedy Spaceflight Centre. Once it begins, the launch window will remain open for roughly 2 hours.


Falcon Heavy's payload is the 6,000-kilogram Arabsat-6A communications satellite for Saudi Arabian telecom giant Arabsat. It will be the Falcon Heavy rocket's second flight, and the first commercial one, after the test in February 2018.

Along with the Hellas Sat-4/SaudiGeoSat-1, the Arabsat-6A satellite under the Arabsat-6G program is the most advanced commercial communications satellites ever built by space technology company Lockheed Martin. It is based on an updated A2100 bus and uses a brand new solar panel technology.

Positioned in the geostationary orbit, Arabsat-6A is expected to last 15 years, provide television, internet, telephone, and secure communication services to the Middle East, Africa and Europe, according to

The Falcon Heavy is the most powerful rocket in the world today. With three first-stage boosters akin to SpaceX's Falcon 9 rockets, the Falcon Heavy boosters, too, are designed to fly back to Earth and be reusable.



The Falcon Heavy's twin boosters made a simultaneous landing on pads at Cape Canaveral successfully during the test flight last year. The core booster wasn't as successful, missing its landing on the 'Of course, I still love you!' drone ship in the Atlantic by a very short distance.

A live stream of the launch will be available half an hour before liftoff on SpaceX's YouTube page.

The first Block 5 variant of SpaceX’s Falcon Heavy rocket has rolled out to Launch Pad 39A for an inaugural launch that could occur as early as April 7th. Minor delays, however, are extremely likely for the second Falcon Heavy launch attempt ever, with the most likely dates resting closer to April 8-11.

With an appearance noticeably deviating from Falcon 9 Block 5’s more tuxedo-esque exterior, Falcon Heavy and its all-new boosters still sport the same polished white skin and some of the black, felt-like thermal protection that helps to make the upgraded boosters so reusable. That reusability will be tested to the extreme as few as two months after launch – assuming all goes well – with the US Air Force’s STP-2 mission, set to reuse both of Falcon Heavy Flight 2’s side boosters, B1052 and B1053.

SpaceX’s second Falcon Heavy rocket has arrived at launch pad 39A at NASA’s Kennedy Space Center in Florida in preparation for a hold-down engine test-firing later today. 


Above all else, it should be noted that the likelihood of Falcon Heavy Flight 2’s actual launch date slipping is not to say that anything at all is technically or operationally wrong with the rocket or ground support equipment (GSE). Rather, it’s simply a dose of pragmatism for a launch date that was originally approved on the range alongside a static fire on March 31st. In other words, SpaceX was anticipating the need for approximately seven days between static fire and launch, a fairly believable target relative to Falcon Heavy’s first launch flow.

Even if SpaceX completes a flawless Falcon Heavy static fire immediately after the 6 pm EDT window opens, this would give company engineers and technicians less than 72 hours to turn the rocket around for launch as soon as 6:36 pm EDT on April 7th. That process involves a huge amount of work, including the actual static fire, safely detanking (removing propellant), returning to Pad 39A’s hangar, installing the payload fairing, ensuring payload health, rolling back out to the pad, and integrating the transporter with the launch mount. Throughout, many checks and double checks are made to ensure that everything is ready for flight.

Safely completing that work in ~72 hours is extremely difficult for Falcon 9, let alone a significantly modified Falcon Heavy preparing for the vehicle’s second launch attempt ever. For reference, excluding a few outlier launches, Falcon 9 Block 5’s mean time between static fire and launch is ~4.7 days, while the mode is 5 days (6/10 launches). Outliers include missions like SSO-A, DM-1, and GPS III SV01, all of which required unique care and caution for various reasons. Chances are good that Falcon Heavy Flight 2 will probably improve upon Flight 1, which took several days to complete a static fire and 13 more days before a launch attempt. Still, the rocket is very unlikely to beat Falcon 9 Block 5’s average time-to-launch.

There is probably a 5% chance of Falcon Heavy launching on April 7th even if the static fire happens right on time and shows all systems running in the green. If SpaceX is unable to fit a static fire into the April 4th window, that will likely slip to 0%. Either way, we can expect SpaceX to provide an updated launch window or rough estimate as early as today, especially if the static fire test is successfully completed. 

In the meantime, drone ship Of Course I Still Love You (OCISLY) – accompanied by a tug boat – is heading nearly 1000 km (620 mi) into the Atlantic Ocean to prepare for the attempted recovery of Falcon Heavy’s center core. In other words, it will likely be the fastest and farther a SpaceX booster has ever traveled while still attempting to land. Just Falcon Heavy’s launch debut, both side boosters will attempt to land back at Landing Zones 1 and 2 (LZ-1 & LZ-2) around 8-10 minutes after liftoff. The 6000-kg (~13,200 lb) Lockheed Martin-built Arabsat 6A satellite will be the rocket’s first commercial payload, likely heading to a high-energy geostationary transfer orbit.

The Event Horizon Telescope, a network of telescopes on mission to observe supermassive black holes at the centres of galaxies, is set to release its first results in a public press conference next week.

We don’t know what the results will be—but they have the potential to be utterly worldview-changing.

“The event horizon of black holes represent the limits of our knowledge,” Priyamvada Natarajan, astronomy and physics professor at Yale University, told Gizmodo by phone this week. “For me, [the Event Horizon Telescope] is almost a precise piece of what the human mind is capable of. I’m having an emotionally excited reaction to all of this.”

Black holes are objects so compact and dense that they contain a region in their gravitational field, their event horizon, beyond which space is so warped that light cannot escape. We have tons of evidence that black holes exist, from bursts of radiation emitted from galactic centres to ripples through spacetime called gravitational waves. But we’ve never seen one up close.

That’s the goal of the Event Horizon Telescope, which operates under a principle called very long baseline interferometry, or VLBI. The “telescope” is actually a collaboration of telescopes around the world, from the United States to Chile to the South Pole, which all observe the same distant object at the same time. The data is brought together at a central location and then decoded to produce higher-resolution images than would be possible with a single telescope. It’s like turning the entire Earth into one large telescope. The resolution increase is mind boggling. Hopefully, the telescope will be able to resolve the center of the galaxy, a region over 25,000 light-years away that is only about the size of Mercury’s orbit around the Sun.

The targets of the telescope’s observing runs thus far have been Sagittarius A*, a radio wave-emitting region of our galaxy that looks a whole lot like a supermassive black hole with a mass 4 million times that of the Sun, as well as the center of the galaxy M87, where there is presumably another supermassive black hole, this one around 7 billion times the mass of the Sun and spewing a high-energy jet of matter.

This week, the National Science Foundation announced that it and the EHT collaboration would hold a press conference in Washington D.C., with simultaneous press conferences in Brussels, Santiago, Shanghai, Taipei, and Tokyo, to announce “a groundbreaking result.” Unfortunately, we don’t know what this result will be—and I’d otherwise prefer not to feed into the hype—but if the result is what we hope it is, it will be incredible, possibly showing the shadow that the black hole creates against the backdrop of the cosmos. It would become one of the most important images in scientific history.

For a taste of what I’m talking about, last year, Avery Broderick, associate professor at the University of Waterloo, sent us a a simulation of what a black hole observed by the EHT might look like:

If we can see the shadow, “that would be absolutely jaw-dropping,” Grant Tremblay, astrophysicist at the Harvard-Smithsonian Center for Astrophysics who was on a committee that approved an EHT upgrade, told Gizmodo by phone. “If we see a shadow the way we think it should, that’s going to be really exciting, a confirmation that although we don’t know how nature works, we’re on the right track.”

But we don’t know what it’s going to show, yet. If it shows something different from astronomers’ expectations, that would be exciting too. Whatever the result, scientists are excited for all of the questions and potential lines of research that will come out of the data release.

I’m trying to treat this all with cautious optimism, since, again, we don’t know what kind of images we’ll see next week. But when scientists call big, internationally broadcast press conferences like this, it’s usually because they have a big result.

Turkey has taken another step towards the purchase in the future of the newest anti-aircraft missile systems S-500 "Prometheus", which only in 2020 will begin to enter into service with the Russian army.

Upon completion of the generally successful election campaign for the ruling Justice and Development Party (JDP) (local elections on March 31), the leader of the JDP, President Recep Tayyip Erdogan, reiterated his desire to be heard by EADaily sources in Ankara deliveries of the S-400 air defense missile system to sign a new large arms contract with Moscow.

Now for the C-500.

Last year, and even earlier, namely after the failed military coup in Turkey in July 2016, the republic’s permanent leader repeatedly pointed out the ambitions of one of the most powerful NATO armies to put on combat duty both C-400 and C-500. Moreover, these ambitions extend not only to the acquisition of defense systems, but also their joint production, which, given the same status of Turkey as part of NATO, the Russian side so far delicately refuses.

It is expected that certain questions regarding the types of the Turkish leader at the C-500 may be clarified on the basis of his regular visit to Moscow and negotiations with Vladimir Putin. On April 8, a meeting of the highest level bilateral cooperation council will be held in the Russian capital.
