How many satellites orbit around mars?

Answer 1

Mars has two very small satellites that orbit very close to its surface. The first spacecraft to visit Mars was the Mariner 4 back in 1965 and several others have visited since that time.
they have 2 satillites
Mars has two natural moons orbiting it. Named Phobos and Deimos.

Answer 2

Mars has two natural satellites, Phobos and Deimos. There are also 3 functioning artificial satellites there: Mars Reconnaissance Orbiter, Mars Odyssey, and Mars Express.

Artificial satellites that are no longer functioning, but still in orbit, around Mars include Mariner 9, the Viking 1 orbiter, and probably the Mars Global Surveyor, though after the MGS entered safe mode the MRO team unsuccessfully tried to image it to determine its orientation, so it may no longer be in orbit; its apapsis is close enough to the surface for atmospheric drag to be a potential factor.

Mars 2, Mars 3, and the Viking 2 orbiter may still be in orbit as well; I couldn't find any hard data one way or the other.

Answer 3

Mars has two moons Phobos ans Deimos.

Phobos:Distance-9000km; Radius-11km; Mass-1.08x1016kg; Discovered in 1877.

Deimos:Distance-23000km; Radius-6km ; Mass-1.80x1015kg; Discovered in 1877.

Answer 4

It has two natural moons, Phobos and Deimos, which are considerably smaller than our own moon and much less regular in shape, being lumpy and uneven. They are believed to be 'captured asteroids'- that is, asteroids that many billions of years ago were drawn into the Martian orbit and have remained there ever since.

There are five artificial ones, although only two remain operational. The oldest one is Mariner 9 which was launched on 30th 1971 and took the first detailed photographs of the Martian surface. It's mission was concluded on 27th October 1972 and it was then switched off, although it continues to orbit Mars to this day and will continue to do so until 2022, when it is expected to fall into Mars's atmosphere and burn up.

The Viking 1 Orbiter was launched in August 1975 and arrived at Mars in June the following year, carrying with it the Viking 1 Lander which descended to the surface to analyse the Martian soil and take photographs. The Orbiter malfunctioned in April 1980 due to depletion of it's altitude correction fuel, so was deactivated, but it remains in orbit in a defunct state and is expected to crash-land on the planet some time in 2019.

NASA launched the Mars Global Surveyor in 1996, which completed it's primary mission in 2001. It was into it's second extended mission when contact was lost on 1st November 2006, resulting in NASA terminating the project two months later. The malfunctioned satellite will continue to orbit the planet until the 2040's.

There is also the Mars Express Orbiter, launched by the European Space Agency on 2nd June 2003, which is carrying out a number of survey missions which are to last until 2014. It carried the ill-fated Beagle 2 lander, which was designed and built by the British and landed on the planet on Christmas Day '03, but nothing was ever heard from the lander after touchdown and the mission was presumed lost due to malfunction.

Finally, there is the Mars Global Surveyor, launched on 12th August 2005. It is analysing Mars's landforms, stratigraphy, minerals and ice-caps, as well as keeping an eye on Martian weather conditions, and although it's primary mission was only for two years it continues to be fully active to this day, and is likely to remain so.

There have been several other Mars satellites launched, ever since the early '60s, but these either crashed into the Martian surface after malfunctioning, or left the Martian orbit after completing their missions and are currently in free orbit around the Sun.

Mars has two natural satellites: it moons Phobos and Deimos.

As of February 2013, there are three artificial satellites in use and orbiting Mars: 2001 Mars Odyssey Mars Express, and Mars Reconnaissance Orbiter.

There are also five other artificial satellites orbiting Mars that are not in use: Mariner 9, Viking 1, Viking 2, Phobos 2, and Mars Global Surveyor.
2 small moons.

Answer 5

Currently, there are several satellites orbiting around Mars. This includes spacecraft from various space agencies such as NASA, ESA, and ISRO. These satellites are studying Mars' atmosphere, surface, and moons, providing valuable data for scientists back on Earth.

Answer 6

There are two natural satellites: its moons Phobos and Deimos. There are also currently five active man-made satellites in orbit, and likely some dead satellites still in orbit as well.

Answer 7

Mars has two small moons: Phobos and Deimos.

Answer 8

Mars has two satelites a.k.a moons called phobos and deimos.

Answer 9

Mars does not have satellites but it does have four moons.
