Spacecraft are designed starting with designs. These designs can take the form of rough sketches on napkins or more detailed engineering drawings created using software such as NX. While NX software is highly valued in aerospace design circles, its acquisition and learning can be quite costly. Siemens PLM Software has decided to give students at

For spacecraft to reach Mars, they must first escape Earth’s gravity by using powerful rocket fuel and launch at exactly the right moment – both planets orbit around the Sun at different speeds and distances; every 26 months or so they come closer together, making travel to Mars much simpler. Spirit A six-wheeled vehicle equipped

Mercury orbits the Sun once every 88 Earth days on an elliptical path which may bring it as close as 29 million miles or as far away as 43 million miles from our star. Magnetic reconnection between the IMF and Mercury’s planet magnetosphere is the most efficient process for mixing plasma, allowing solar wind to

Saturn boasts seven rings, which consist of icy chunks encircling it. They’re named alphabetically from A to G and average only 30 feet or meters high on average. Saturn and its moons exert gravitational pull that creates patterns known as bending waves or spiral density waves in its rings, whereby bands move closer or further
