Someday, manned missions may be going to Phobos and Deimos. Scientists have discussed the possibility of using one of the Martian moons as a base from which astronauts could observe the Red Planet and launch robots to its surface, while shielded by miles of rock from cosmic rays and solar radiation for nearly two-thirds of every orbit.
And here are some great images of both Phobos and Deimos. I suppose there are many thousands near Mars asteroids, which maybe could be helpful for Mars exploration. Some surely come close to both Earth and Mars and are natural Earth-Mars cyclers with resources we could extract without having to launch them from Earth. I think some of the sources used for this article are outdated. One possibility is that they formed like the Moon, out of debris from a relatively recent impact on Mars.
Should fit politically as a compromise in the endless Mars, Moon and asteroids target choice debate. Just a week or so ago there was an article saying the grooves might be due to Phobos being almost breaking up already.
That gave me an idea and I asked Wolfram Alpha what is the gravitational binding energy of Phobos. Maybe Elon retired to the desolate deserts on Mars, wants a spectacular view for his entertainment, and dear Phobos will be forever gone. Skip to content. Arizona , NASA. Like this: Like Loading How the moons formed remains unsolved.
But recent models instead suggest that they could have formed from the debris flung up from Mars after a huge impact long ago. Deimos, the smaller of the two moons, orbits Mars every 30 hours and is less than 10 miles across. Its larger sibling Phobos bears many scars, including craters and deep grooves running across its surface.
Scientists have long debated what caused the grooves on Phobos. Since the s, humans have robotically explored Mars more than any other planet beyond Earth. Currently, eight missions from the U. But getting safely to the red planet is no small feat.
Of the 45 Mars missions launched since , 26 have had some component fail to leave Earth, fall silent en route, miss orbit around Mars, burn up in the atmosphere, crash on the surface, or die prematurely. More missions are on the horizon, including some designed to help search for Martian life.
NASA is building its Mars rover to cache promising samples of Martian rock that a future mission would return to Earth. In , the European Space Agency and Roscosmos plan to launch a rover named for chemist Rosalind Franklin , whose work was crucial to deciphering the structure of DNA.
The rover will drill into Martian soil to hunt for signs of past and present life. Other countries are joining the fray, making space exploration more global in the process.
In July , the United Arab Emirates is slated to launch its Hope orbiter , which will study the Martian atmosphere. Perhaps humans will one day join robots on the red planet. NASA has stated its goal to send humans back to the moon as a stepping-stone to Mars. Will humans eventually build a scientific base on the Martian surface, like those that dot Antarctica? How will human activity affect the red planet or our searches for life there?
Time will tell. But no matter what, Mars will continue to occupy the human imagination, a glimmering red beacon in our skies and stories. All rights reserved. Mars Nearing Earth In , the Hubble Space Telescope snapped this photo of the red planet 11 hours before its closest approach to Earth in 60, years.
Longer year and shifting seasons With a radius of 2, miles, Mars is the seventh largest planet in our solar system and about half the diameter of Earth. Share Tweet Email.

Epic floods leave South Sudanese to face disease and starvation. The dominant feature on Phobos, it found, was a crater six miles 10 kilometers wide—nearly half the width of the moon itself.
