Transparent Russian Rocket

The Soyuz rocket, a legendary figure in the history of space travel, is a family of expendable launch systems crafted by Russia’s premier space agency, Roscosmos. Since its inception in the swinging 60s, this formidable rocket has undergone numerous improvements and has established itself as one of the most widely used and trusted space launch vehicles in the world.

With its versatility and dependability, the Soyuz has launched missions for a diverse array of organizations and nations, including the Soviet Union, Russia, the European Space Agency, and even NASA. Whether it’s carrying crew and cargo to low Earth orbit, or transporting astronauts to the International Space Station, the Soyuz has proven its worth time and time again.

Fueling this rocket’s success is its power source: a mixture of liquid oxygen (LOX) and kerosene. The Soyuz’s first stage boasts four liquid-fueled engines, while its second stage is powered by a solitary engine. The third and final stage employs a solid-fueled engine. This fuel combination, which has been utilized in many early and contemporary rockets, is known for its high energy output, making it the ideal choice for spacecraft propulsion systems. The efficiency, affordability, and reliability of the LOX and kerosene combination have made Continue reading Transparent Russian Rocket

Крым космический: ближний и дальний космос. Фильм 1

Роскосмос Медиа запускает серию фильмов «Крым космический», которая соединит славную историю отечественной космонавтики и её современность.

В первом фильме говорим об истории полуострова и о том, как его природа благоприятствует науке. Здесь, в Таврическом университете, работал один из создателей научного космизма и ноосферы академик Владимир Иванович Вернадский. А ещё преподавал академик и писатель-фантаст, автор «Плутонии» и «Земли Санникова» Владимир Афанасьевич Обручев. Сегодня на крымской земле работают не только историки, археологи и биологи, но и астрономы, и астрофизики. Ведь звёздное небо Крыма — уникально.

Приятного просмотра!

Earth in 1000 Years

There are signs that Earth’s great stores of ice on Greenland and Antarctica are beginning to melt in the wake of rising sea surface temperatures. With sea levels beginning to rise, scientists are looking back at past geological ages to understand the influence of ocean currents and other factors. They are searching for insights into where our planet may be headed a millennium into the future.

Reusable Single Stage to Orbit Rocket (SSTO)

Douglas Aircraft’s SASSTO, short for “Saturn Application Single Stage to Orbit”, was a single stage to orbit (SSTO) reusable launch system designed by Philip Bono’s team in 1967. SASSTO was a study in minimalist designs, a launcher with the specific intent of repeatedly placing a Gemini capsule in orbit for the lowest possible cost. The SASSTO booster was based on the layout of the S-IVB upper stage from the Saturn family, modified with a plug nozzle.
