What part of the speed of light should bethe speed of a particle so that its kinetic energy is equal to its rest energy? We know the answer, and we also know what happened in the high-tech world over the last week.
one. Soon we will fly on plants and mustard! At least all this goes. The other day, for example, the airline Etihad Airways conducted the first commercial flight of an aircraft operating on biofuels - for this purpose biofuels were used based on salting (plants from the coastal marine strip with a high salt concentration in the soil). In other words, kerosene was simply diluted with a biofuel in the ratio of 50 to 50 - the plane cannot fly on biofuel alone.
Following the UAE, the Netherlands announced their plans. The country's defense ministry said it wanted to transfer all the country's military aviation to fly biofuel. At first, all military aircraft will fly with a 20 percent addition of biofuels, but over time, its content will be increased to 70%.
Do Russian airlines plan at leastPartially use biofuel for commercial flights in the near future? The press service of the S7 Group and Aeroflot told us that there are no such plans for the air carriers yet.
2 Meanwhile, a private aerospace companyBlue Origin, which is owned by billionaire Jeff Bezos, conducted the successful launch of the New Shepard rocket, and then the landing of the spent stage and the capsule for the crew. This is the first launch of the New Shepard rocket in 2019 and, in general, the tenth successful test for the company.
New Shepard is a fully reusable rocket. In other words, almost every element of its system can be restored for reuse. It consists of two main parts - actually, the accelerator itself (launch vehicle), as well as the capsule, in which it is planned to deliver people to a height of about 100 kilometers above the Earth's surface.
With each passenger, New Shepard will be asked for $ 200,000 per ticket. The previous modification flew into space 5 times, until in 2016 the company replaced it with a new version.
3 Want to see 16 times the sun rises andsunsets in a day? Feel your body effects of microgravity and enjoy the fantastic views of our planet from the side? It is likely that in 2021 you will have such an opportunity. True, in the presence of 9.5 million dollars.
It is in this amount that the American company OrionSpan is evaluating the opportunity to spend 12 days aboard the Aurora Station, the first luxury space hotel to be opened in 2 years. Space Hotel Aurora Station will be a modular station that can accommodate 6 people - 4 tourists and 2 crew members. It is assumed that it will be in low Earth orbit at an altitude of 320 km.
Guests of the hotel will be able to enjoy sunrises,maintain constant video calls with relatives on Earth (they promise access to high-speed Wi-Fi), relax in specially designed sleep cells and eat high-quality space rations. Well, another thing!
four. We all will die? In 2068, the asteroid Apophis could fall to Earth, according to a report prepared by scientists from the department of celestial mechanics at St. Petersburg State University.
Almost immediately after its discovery, scientists beganmake predictions about the probability of a collision of an object with the Earth. So in 2004, scientists suggested that the likelihood of Apophis falling to Earth in 2029 would be 1 in 45,000. Some time later, radar observations excluded the possibility of a collision in 2029, but due to inaccurate initial data, there was a probability of a collision of this object with our planet in 2036 and subsequent years.
Given the size of the asteroid, the real consequencesfrom his fall on the surface of the planet are estimated catastrophic, said our interlocutor at St. Petersburg State University. For example, it is possible to defeat a territory the size of a middle country.
Before the approach of Apophis to the Earth in 2068, we expect several more earlier encounters with a small celestial body.
five. No sooner had the starship rocket even flown asalready dropped due to strong wind. The photos posted by different users on Twitter show that the upper part of the future apparatus lies on its side and is rather crumpled. Ilon Mask said that he was aware of this incident. In addition, the head of SpaceX added that the restoration work may take several weeks.
In the future, SpaceX plans touse a new super-heavy rocket to deliver people and cargo not only to near-earth orbit, but also to the moon and mars. The starship prototype was assembled fairly quickly near the village of Boca Chica, where SpaceX is building a new space center.
I want to believe that it will be more responsible to assemble a rocket than to mount it to the ground.
