The giant planet completes one rotation every 10.5 hours.

This image shows the recent observations of the planets Mars and Saturn made with the NASA/ESA Hubble Space Telescope. A dust storm is ravaging the planet. Part of this is because it's closer to Earth than it typically is, but it's also because it's closer to the sun, explains Paige Godfrey, the director of research and education at Washington, Conn. -based Slooh.

According to NASA, Mars Opposition begins Friday, July 27 around midnight.

The two planets will be just 57.6 million km apart on July 31, while Mars will appear brightest on July 27-30, making it easier to be seen with the telescope or the naked eye. This close distance puts Mars at its brightest appearance in the night sky since the 2003 opposition. As a outcome, there's a point in every Martian year where Mars is closest to the Earth.

On the other hand, from 1:15 am to 2:43 am, the moon will be in the middle of the Earth's shadow and will appear reddish in colour. With summer in the northern hemisphere, the atmosphere is now more active. Small, mid-latitude puffs of clouds are also visible. Unfortunately, we're getting the short end of the stick on this one. These findings are very encouraging for all future missions towards Mars.

This instrument, which is called the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS for short) emits radio waves toward the planet.

Each Martian year, moderately large dust storms cover continent-sized areas and last for weeks at a time. "So Mars is illuminated by the Sun - like a full moon would be", Gilmore said. In May, NASA launched another spacecraft, the InSight Mars lander, that will dig under the surface after it reaches a flat plain just north of the Martian equator in November.

The Sun, Earth and Mars will form a straight line in the solar system as the planets' orbits line up.

For those of you disappointed that you won't be able to see the lunar eclipse, you will still have something to look at in the night sky.

Researchers said they are not sure how far down it goes, but that it may be around three feet (one meter) deep.

Evidence for the Red Planet's watery past is prevalent across its surface in the form of vast dried-out river valley networks and very big outflow channels clearly imaged by orbiting spacecraft. Hubble took advantage of this preferred configuration and imaged both planets to continue its long-standing observation of the outer planets in the Solar System.
