Accordingly, both planets were the closest 15 years ago, in 2003, with only 56 million kilometers in between.
Surface features on Mars suggest that the planet was once warmer and wetter eons ago, but research from spacecraft on and around Mars in recent years have shown that much of the planet's atmosphere and its moisture were lost to space in ancient times.

The last time Mars was close to Earth was in 2003, when the red planet came within 34.6 million miles (55.7 million km) of our planet.
If you missed it, don't believe any insane stories you may hear about its apparent size.
If you have a telescope at home you should get a good view of the planet but Mars will be just as easily visible to the naked eye. That was the closest we've been to Mars since 57,617 BC.
"You can't miss it, just find a clear viewing point and look up".
A new study that was published on Monday in Nature Astronomy may have cast doubts on whether humans can terraform Mars, but Elon Musk is having none of it and still believes that we will be able to colonize the red planet.
Saturn is by far the solar system's most photogenic planet, and in this latest Hubble Space Telescope snapshot it is especially so because Saturn's magnificent ring system is near its maximum tilt toward Earth (which was in 2017). In fact, Aldrin spoke passionately in the webcast about a future hope to first return to the moon, and then Mars. "If that were true, we'd be in big trouble given the gravitational pulls on Earth, Mars and our moon!"
Since the red planet and the sun appear on opposite sides of the sky, Mars is in opposition, according to NASA. Los Angeles' Griffith Observatory will provide a live online view of Mars early Tuesday. The planet was observed near opposition, when the Sun, Earth and Mars are lined up, with Earth sitting in between the Sun and Mars.
"There's one very bright orange-coloured star in the sky". It has a very helpful atmosphere, which, being primarily Carbon dioxide with some nitrogen and argon and a few other trace elements, means that we can grow plants on Mars just by compressing the atmosphere.
