Theyre launching spacecraft when Earth and Mars reach their closest point. Cassini's calculation was only off by 7% compared to today's more accurate measurements. Scientists don't expect to find living things currently thriving on Mars. In theory, the closest Mars and Earth would getis when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). Inclusion, Diversity, Equity & Accessibility (IDEA). Mars was named by the ancient Romans for their god of war because its reddish color was reminiscent of blood. Planets farther away would have AU . Though, that's not the fastest, either. Engineers must calculate the ideal orbits for sending a spacecraft from Earth to Mars. They start at Earths orbit, and then raise their orbit until they intersect the orbit of Mars; right when Mars is at that point. Such oppositions occur roughly every 26 months. Like throwing a dart at a moving target, they must calculate where the planet will be when the spacecraft arrives, not where it is when it leaves Earth. Remind students that Pluto is no longer considered a planet in our solar system; it was downgraded to the status of dwarf planet in 2006. Every 15 to 17 years we witness very close Mars oppositions when Earth passes between Mars and the sun during Mars' perihelion (closest point to the sun). Mars Close Approach happens about every 26 months. They used the parallax method to calculate the distance to Mars with surprising accuracy. And while here on Earth the seasons are evenly spread over the year, lasting 3 months (or one quarter of a year), on Mars the seasons vary in length because of Mars' elliptical, egg-shaped orbit around the Sun. Nowadays, with several spacecraft orbiting or roaming along the surface of the Red Planet, scientists can use the speed of light to determine how far away Mars is from Earth, by measuring the time it takes for signals to reach Martian spacecraft, according to Universe Today (opens in new tab). Have students recalculate the number of paces for each planets orbit, as constrained by the size of the available area. If you need imaging gear, consider our best cameras for astrophotography and the best lenses for astrophotography. Occasionally, winds on Mars are strong enough to create dust storms that cover much of the planet.
