After launch, the third stage pumps on both launchers were unable to develop enough pressure to commence ignition, so Earth parking orbit was not achieved. Mars A was a Mars fly-by mission, launched on October 24, and Mars B an intended first Mars lander mission, launched in late December of the same year Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars trajectory.

Mars 1 Beta Nu 1 , an automatic interplanetary spacecraft launched to Mars on November 1, , was the first probe of the Soviet Mars probe program to achieve interplanetary orbit. In , both Soviet probe launches, of Zond A on June 4, and Zond 2 on November 30, part of the Zond program , resulted in failures. Zond A had a failure at launch, while communication was lost with Zond 2 en route to Mars after a mid-course maneuver, in early May Both probes were lost in launch-related complications with the newly developed Proton rocket.

In May , one day after Mariner 8 malfunctioned at launch and failed to reach orbit, Cosmos Mars C , a heavy probe of the Soviet Mars program M, also failed to launch. This spacecraft was designed as an orbiter only, while the next two probes of project M, Mars 2 and Mars 3 , were multipurpose combinations of an orbiter and a lander with small skis-walking rovers that would be the first planet rovers outside the Moon.

They were successfully launched in mid-May and reached Mars about seven months later. On November 27, the lander of Mars 2 crash-landed due to an on-board computer malfunction and became the first man-made object to reach the surface of Mars.

On 2 December , the Mars 3 lander became the first spacecraft to achieve a soft landing , but its transmission was interrupted after The Mars 2 and 3 orbiters sent back a relatively large volume of data covering the period from December to March , although transmissions continued through to August.

By 22 August , after sending back data and a total of 60 pictures, Mars 2 and 3 concluded their missions. The images and data enabled creation of surface relief maps, and gave information on the Martian gravity and magnetic fields. In , the Soviet Union sent four more probes to Mars: All missions except Mars 7 sent back data, with Mars 5 being most successful. Mars 5 transmitted just 60 images before a loss of pressurization in the transmitter housing ended the mission. Mars 6 lander transmitted data during descent, but failed upon impact.

Mariner 3 and Mariner 4 were identical spacecraft designed to carry out the first flybys of Mars. Mariner 3 was launched on November 5, , but the shroud encasing the spacecraft atop its rocket failed to open properly, dooming the mission.

Mariner 4 flew past Mars on July 14, , providing the first close-up photographs of another planet. The pictures, gradually played back to Earth from a small tape recorder on the probe, showed impact craters. No magnetic field [49] [50] or Martian radiation belts [51] were detected. The new data meant redesigns for then planned Martian landers, and showed life would have a more difficult time surviving there than previously anticipated. They were sent at the next launch window, and reached the planet in During the following launch window the Mariner program again suffered the loss of one of a pair of probes.

Mariner 9 successfully entered orbit about Mars, the first spacecraft ever to do so, after the launch time failure of its sister ship, Mariner 8. When Mariner 9 reached Mars in , it and two Soviet orbiters Mars 2 and Mars 3 , see Mars probe program above found that a planet-wide dust storm was in progress.

The mission controllers used the time spent waiting for the storm to clear to have the probe rendezvous with, and photograph, Phobos. When the storm cleared sufficiently for Mars' surface to be photographed by Mariner 9, the pictures returned represented a substantial advance over previous missions.

These pictures were the first to offer more detailed evidence that liquid water might at one time have flowed on the planetary surface. They also finally discerned the true nature of many Martian albedo features. For example, Nix Olympica was one of only a few features that could be seen during the planetary duststorm, revealing it to be the highest mountain volcano , to be exact on any planet in the entire Solar System , and leading to its reclassification as Olympus Mons.

The Viking program launched Viking 1 and Viking 2 spacecraft to Mars in ; The program consisted of two orbiters and two landers — these were the first two spacecraft to successfully land and operate on Mars. The primary scientific objectives of the lander mission were to search for biosignatures and observe meteorologic , seismic and magnetic properties of Mars.

The results of the biological experiments on board the Viking landers remain inconclusive, with a reanalysis of the Viking data published in suggesting signs of microbial life on Mars. The Viking orbiters revealed that large floods of water carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers. Areas of branched streams, in the southern hemisphere, suggest that rain once fell. Mars Pathfinder was a U. It consisted of a lander and a small Mars Global Surveyor launched on November 7, , and entered orbit on September 12, After a year and a half trimming its orbit from a looping ellipse to a circular track around the planet, the spacecraft began its primary mapping mission in March It observed the planet from a low-altitude, nearly polar orbit over the course of one complete Martian year, the equivalent of nearly two Earth years.

Mars Global Surveyor completed its primary mission on January 31, , and completed several extended mission phases. The mission studied the entire Martian surface, atmosphere, and interior, and returned more data about the red planet than all previous Mars missions combined.

The data has been archived and remains available publicly. Among key scientific findings, Global Surveyor took pictures of gullies and debris flow features that suggest there may be current sources of liquid water, similar to an aquifer , at or near the surface of the planet. Similar channels on Earth are formed by flowing water, but on Mars the temperature is normally too cold and the atmosphere too thin to sustain liquid water.

Nevertheless, many scientists hypothesize that liquid groundwater can sometimes surface on Mars, erode gullies and channels, and pool at the bottom before freezing and evaporating. Magnetometer readings showed that the planet's magnetic field is not globally generated in the planet's core, but is localized in particular areas of the crust.

Data from the spacecraft's laser altimeter gave scientists their first 3-D views of Mars' north polar ice cap. Faulty software uploaded to the vehicle in June caused the spacecraft to orient its solar panels incorrectly several months later, resulting in battery overheating and subsequent failure. Its mission is to use spectrometers and imagers to hunt for evidence of past or present water and volcanic activity on Mars. The lander carried a digging device and the smallest mass spectrometer created to date, as well as a range of other devices, on a robotic arm in order to accurately analyze soil beneath the dusty surface to look for biosignatures and biomolecules.

The orbiter entered Mars orbit on December 25, , and Beagle 2 entered Mars' atmosphere the same day. However, attempts to contact the lander failed. Communications attempts continued throughout January, but Beagle 2 was declared lost in mid-February, and a joint inquiry was launched by the UK and ESA. The Mars Express Orbiter confirmed the presence of water ice and carbon dioxide ice at the planet's south pole, while NASA had previously confirmed their presence at the north pole of Mars.

The lander's fate remained a mystery until it was located intact on the surface of Mars in a series of images from the Mars Reconnaissance Orbiter. Beagle 2 is the first British and first European probe to achieve a soft landing on Mars. The Mars Reconnaissance Orbiter MRO is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit.

Additionally, MRO is paving the way for upcoming generations of spacecraft through daily monitoring of Martian weather and surface conditions, searching for future landing sites, and testing a new telecommunications system that enable it to send and receive information at an unprecedented bitrate , compared to previous Mars spacecraft.

Data transfer to and from the spacecraft occurs faster than all previous interplanetary missions combined and allows it to serve as an important relay satellite for other missions. The NASA Dawn spacecraft used the gravity of Mars in to change direction and velocity on its way to Vesta , and tested out Dawn 's cameras and other instruments on Mars.

It consisted of a lander aimed to retrieve a sample back to Earth from Mars' moon Phobos , and place the Chinese Yinghuo-1 probe in Mars' orbit. The Fobos-Grunt mission suffered a complete control and communications failure shortly after launch and was left stranded in low Earth orbit , later falling back to Earth. The rover carries instruments designed to look for past or present conditions relevant to the past or present habitability of Mars.

The mission is a technology demonstrator, and as secondary objective, it will also study the Martian atmosphere. It also made ISRO the second space agency to reach Mars orbit on its first attempt the first national one, after the international ESA , and also the first Asian country to successfully send an orbiter to Mars. It was injected into Mars orbit on 19 October to gain a better understanding of methane CH 4 and other trace gases present in the Martian atmosphere that could be evidence for possible biological or geological activity.

The CubeSats separated from the Atlas V booster 1. Other future mission concepts include polar probes, Martian aircraft and a network of small meteorological stations. Many people have long advocated a human mission to Mars , perhaps eventually leading to the permanent colonization of Mars , as the next logical step for a human space program after lunar exploration.

Aside from the prestige such a mission would bring, advocates argue that humans would easily be able to outperform robotic explorers, justifying the expense. Aerospace engineer Bob Zubrin is one of the proponents of such missions. Various asteroids , moons , and places on Mars can be mined while crops are initially being planted. Some have also stated that persons should stay on Earth, but get food and resources from Mars and surrounding asteroids, moons, greenhouses in space and other structures.

Some critics contend unmanned robots can perform better than humans at a fraction of the expense. If life exists on Mars, a human mission could contaminate it by introducing earthly microbes, so robotic exploration would be preferable. They called it "Journey to Mars". The plan operates through three distinct phases leading up to fully sustained colonization. On August 28, , NASA funded a year long simulation to study the effects of a year long Mars mission on six scientists.

The scientists lived in a bio dome on a Mauna Loa mountain in Hawaii with limited connection to the outside world and were only allowed outside if they were wearing spacesuits. Mars Direct , a low-cost human mission proposed by Robert Zubrin , founder of the Mars Society , would use heavy-lift Saturn V class rockets, such as the Ares V , to skip orbital construction, LEO rendezvous, and lunar fuel depots.

A modified proposal, called " Mars to Stay ", involves not returning the first immigrant explorers immediately, if ever see Colonization of Mars. The challenge, complexity and length of Mars missions have led to many mission failures.

Two Soviet probes were sent to Mars in as part of the Phobos program. Phobos 1 operated normally until an expected communications session on 2 September failed to occur. The problem was traced to a software error, which deactivated attitude thrusters causing the spacecrafts' solar arrays to no longer point at the Sun, depleting Phobos 1 batteries. Phobos 2 operated normally throughout its cruise and Mars orbital insertion phases on January 29, , gathering data on the Sun, interplanetary medium, Mars, and Phobos.

Shortly before the final phase of the mission, during which the spacecraft was to approach within 50 m of Phobos' surface and release two landers, one a mobile 'hopper', the other a stationary platform, contact with Phobos 2 was lost.

The mission ended when the spacecraft signal failed to be successfully reacquired on March 27, The cause of the failure was determined to be a malfunction of the on-board computer. Mars 96 , an orbiter launched on November 16, by Russia failed, when the planned second burn of the Block D-2 fourth stage did not occur.

The Mars Climate Orbiter was noted for mixing up U. The European Space Agency has also attempted to land two probes on the Martian surface; Beagle 2 , a British-built lander that failed to deploy its solar arrays properly after touchdown in December , and Schiaparelli , which was flown along the ExoMars Trace Gas Orbiter. Contact with the Schiaparelli EDM lander was lost 50 seconds before touchdown. From Wikipedia, the free encyclopedia. Not to be confused with Colonization of Mars. List of missions to Mars.

Die Tür sollte ebenfalls gut begehbar sein und mindestens 80 cm in der Breite betragen, damit man auch einmal mit einer Schubkarre Scheibtruhe hineinkommt. Als Ausgang für die Hühner baut man eine kleine Klappe, die ca. Damit durch sie nicht die Einstreu hinausgescharrt werden kann, sollte sie 30 cm über dem Boden gebaut werden.

Nachts muss der Hühnerstall geschlossen werden, damit keine Tiere wie Fuchs, Marder oder Iltis eindringen können, die meist alle Hühner auf einmal erledigen.

Man muss damit rechnen, dass sich die Hühner, vor allem im Winter, sehr oft im Stall aufhalten. Deshalb ist auch die Inneneinrichtung sehr wichtig. Darin können sie ausgiebig scharren und im Sand baden, was zur Körperpflege sehr wichtig ist.

Zur Futteraufnahme stellt man am Besten so genannte Futterautomaten auf. Sie fassen meist ca. Einen ähnlichen Automaten verwendet man auch für das Trinkwasser.

Auch in diesen läuft immer nur soviel Wasser nach, wie die Hühner trinken. Reines Körnerfutter kann man jedoch auch einfach in die Einstreu werfen. Die Hühner picken es dort ebenso gerne auf. Zum Nächtigen und zur Ruhe brauchen Hühner Sitzstangen.

Diese sollten im oberen Drittel des Stalles angebracht werden, möglichst rund sein und ca. Pro Huhn veranschlagt man 20 — 30 cm Platz. Es müssen immer genug freie Plätze auf den Sitzstangen vorhanden sein. Unter den Sitzstangen hat sich ein Kotbrett sehr bewährt. Dieses sollte man ca. Das Kotbrett sollte aus einer festen Spanplatte mit einem dreifachen Teeraufstrich bestehen. Unter das Kotbrett kann man zwei längsseitige Verstrebungen anbringen, die ein Durchbiegen der Spannplatte verhindern.

Dadurch kommen die Hühnern nicht mit ihrem Kot in Kontakt. Zum Eierlegen brauchen die Hühner ein Nest. Hier gibt es viele Möglichkeiten. Anfangs können Sie es ruhig einmal mit einer einfachen Holzkiste als Nest versuchen, die mit Heu gut ausgepolstert ist.

Damit die Hühner gleich kapieren, dass dies das Nest darstellen soll, können Sie sich im Fachhandel ein oder mehrere Gipseier kaufen und diese ins Nest legen. Gerne nehmen die Hühner ein Nest an, das erhöht aufgestellt ist.

Bei mir sitzen sie am liebsten direkt unter dem Dach. Für je fünf Hühner sollte man ein Nest einberechnen, hält man jedoch nur 5 Hühner, so sind zwei Nester besser.

Auch wenn zwei Hennen zusammen auf ein Nest wollen, gehen oftmals Eier zu Bruch. Aus diesen Gründen rate ich sehr zu einem so genannten Europanest. Dadurch kann keine zweite Henne mehr eindringen, was meist zu Konflikten führt. Durch das Gewicht der Henne im Nest wird der Boden hinten nämlich leicht nach unten gedrückt, was dazu führt, dass sich der Boden vorne etwas hebt.

Im Nest befindet sich eine Kokosmatte, auf der die Henne relativ bequem sitzt. So gemütlich wie im Heunest ist es zwar nicht, aber trotzdem wird das Nest gerne angenommen.

In der Mitte dieser Kokosmatte befindet sich ein Loch, durch das das gelegt Ei dann sofort rollt. Unter dem Nest ist eine Schublade mit einem Drahtboden, auf den das Ei kullert. Deshalb haben auch eierfressende Hennen keine Chance, da das Ei sofort verschwindet. Sie können das Ei dann bequem und sauber aus der Schublade holen.

Für den strengen Züchter sind jedoch auch diese Europanester nicht gut genug. Er greift zu einem sogenannten Fallennest. Der Züchter muss die Henne dann befreien. Dies ist ein beispielhafter Grundriss eines Stalles.
