The head of ULA explains why the American alternative RD-180 has been under development for so long

The head of ULA explains why the American alternative RD-180 has been under development for so long

Russian-speaking critics of Elon Musk in particular and of the entire American cosmonautics in general often forget that SpaceX has serious competitors in the United States that have suffered greatly from the actions of this company. Under the pressure of the success of the eccentric billionaire's firm, they are forced to get out as best they can. In such an environment, the constant delays in the development of the Atlas V successor using Russian RD-180 engines - ULA's Vulcan Centaur missiles - look odd. So Tori Bruno decided to try

14 years, a billion dollars and a delay of two years: due to unavailability of NASA spacesuits, landing on the moon is postponed

14 years, a billion dollars and a delay of two years: due to unavailability of NASA spacesuits, landing on the moon is postponed

An internal review of the Artemis program revealed a number of serious delays in the development of its main components. Most likely, the planned American landing on the moon in 2024 will have to be postponed due to the unavailability of spacesuits. Special suits for extravehicular activities on the surface of a natural satellite of the Earth have been created since 2007 and they will cost the US budget a billion dollars, but still will not be ready on time

Lunar Orbital Platform-Gateway: Lunar Gateway to Deep Space

Lunar Orbital Platform-Gateway: Lunar Gateway to Deep Space

The project, formerly known as the Deep Space Gateway, is the most realistic alternative to the International Space Station. However, “alternative” is not quite the right word, because the new station, unlike the ISS, will be in the orbit of the Moon

Russian-Chinese lunar station: what will come of this PR project?

Russian-Chinese lunar station: what will come of this PR project?

Roskosmos has stunned the world with the news: Russia and China will create a scientific lunar station together. It is truly amazing, because neither of these two countries will be able to land a person on the Moon before the second half of the 2020s, what kind of station can we talk about there? More importantly, what could such a station do and does it make sense at all? Let's try to figure out all this, as well as why both Moscow and Beijing will have to abandon the project - previously, of course, having spent a lot of money on it

Starlink Constellation will provide 90% of all dangerous encounters in low-Earth orbit: there are already 1,600 of them weekly

Starlink Constellation will provide 90% of all dangerous encounters in low-Earth orbit: there are already 1,600 of them weekly

Orbital mechanics for a person unfamiliar with its intricacies looks not at all intuitive. Considering the speed of spacecraft movement, even their passage at a distance of a kilometer from each other is considered potentially dangerous. Now half of these events - 1,600 weekly - take place with the participation of Starlink satellites. And in the future, this number will reach truly astronomical proportions, which greatly worries specialized specialists

Cosmodrome transformation, or How to open the gates to space

The cosmic future is looming with a growing wave of launches. Launch pads become cramped for the space players' grand plans. In order not to get stuck on Earth in a narrow place, it is necessary to expand the passage into space - this is how the word "cosmodrome" is translated from the Greek. This, however, requires a fundamentally new way of thinking. How to open the gates to space - in our material

Who will the Dragon bite off the head?

Who will the Dragon bite off the head?

The successful launch of Crew Dragon will hit the Russian cosmonautics: it will lose hundreds of millions of dollars from the delivery of American astronauts. The United States may abandon the ISS, and then Roscosmos will have a difficult time. But there are more than just those affected: SpaceX's new ship could be a crucial element in … reaching the moon. And this despite the fact that the Crew Dragon seems to be unsuitable for flying to it. Let's try to figure out why

Colony on Mars by 2050: will Elon Musk build a city on the Red Planet

Colony on Mars by 2050: will Elon Musk build a city on the Red Planet

SpaceX expects to have a colony of a million people on Mars by 2050. It sounds absurd: there are only 30 years left, and there are still many years before the first flight to Mars. Some scholars, including Russian scientists, regard Musk's plans as "fantasy" and "propaganda." Nevertheless, the construction of a millionth colony on the Red Planet itself is quite real. Let's figure out why and why it is so difficult to believe in the rest of the world

Anniversary of the disastrous Shuttle program: an ominous warning for Starship?

Anniversary of the disastrous Shuttle program: an ominous warning for Starship?

Forty years ago, in April 1981, the Shuttles began their flights into space, and ten years ago they stopped. Usually they write about them: they completed the tasks, they just turned out to be too expensive. We will show the opposite: the original goal of these reusable ships was cheapness, so from the very beginning the project was a disaster. The trouble is this: the general idea behind the Shuttles is similar to that behind the fundamentally new means of space flight - Starship. Will Elon Musk's brainchild repeat an unenviable fate to
