The whole world is waiting for NASA’s Orion spacecraft to return to Earth. Artemis and Orion spacecraft are a project that took many years and spent billions. The Orion probe, which went all the way to the moon and took pictures, brought a lot of valuable data back to Earth. It is expected to land…
The first “blow down” test of the trisonic wind tunnel, much awaited by the Indian scientific community, took place on 8 December 2022 at the Vikram Sarabhai Space Center in Thiruvananthapuram. Trisonic wind tunnels can be used to test the aerodynamic design of rockets and re-entry spacecraft, and to evaluate the load distribution, pressure, acoustic…
NASA has tested lofted technology that it hopes will help land humans on Mars. The full name of the mission is Low-Earth Orbit Flight Test of Inflatable Decelerator (LOFTID). The system consists of a heat shield, a probe, a propulsion system and a parachute, all of which are connected by circular tubes of air connected…

One man who went through such a situation is Sergei Krikalev, a Soviet/Russian cosmonaut. The Mir space station…
Zero gravity can be created artificially Objects have weight because they are attracted by the earth. Acceleration due to gravity is 9.8 meters per second. Even if an object is dropped in a controlled manner with the same acceleration, it will feel weightless during the fall. So if a human-carried vehicle can be brought as…
For decades, the standard survival kit carried by Russian astronauts aboard the Soyuz spacecraft consisted of a specially-made gun and a few dozen bullets. This was to protect the astronauts from wild animals when they landed back in the Siberian desert. They were the only armed spacefaring nation, From space back to Earth’s atmosphere, re-entry…
NASA has launched four probes into space to communicate with extraterrestrials. Along with that it is used for the study of the universe, the planets of the solar system and so on. Voyager 1 and 2 in 1977. Before this, they were Pioneer 10 in 1972 and Pioneer 11 in 1973.(Out of which Voyager 1…
