The type of map shown below, or the method of showing the earth as a whole, is called Cylindrical projection. This is the map we usually see. Here, the surface of the earth is wrapped around an imaginary cylinder and then spread out to make it look like a flat earth. At that time, the…
The European Space Agency’s spacecraft that carried Philae, the first spacecraft to land on a comet. On March 2, 2004, Rosetta was launched by an Ariane 5 rocket from Kourou, French Guiana, on a 10-year mission to comet 67P/Churyumov-Gerasimenko. Rosetta’s 654-million-km journey entered orbit around the comet on August 6, 2014, and then landed the…
Percy returned to Mars in July 2020. After nearly a year of exploration, yesterday (21 Dec 2022) Percy began one of his main missions, sample deposition. Many holes were dug on the surface of Mars and soil, rock dust, etc. were collected from them in small titanium tubes, sealed and deposited in various places on…
1) Probe comes down by running engine in opposite direction to orbital motion and reducing horizontal speed. 2) Orientation of probe is controlled according to descent.3) Controls downward and lateral speed.4) Hover after reaching a certain height after reducing speeds. 5) Hover and take pictures of the lunar surface below and process the image to…
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…
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…
The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur. watch video
