Strange structures and objects on Mars that cannot be explained as the result of simple physical and chemical processes
When Nasa and other authorities lay out easy to find pictures and descriptions of Mars, they always dump out an abundance of material that best possibly present the planet as a dry, cold and deserted place. They exhibit plenty of material that illustrate the geological history of the planet, but avoid presening features that cannot fairly easily be explained as the result of simple geological processes. When they cannot avoid to show features that obviously have a more complicated origine, they never comment on them by own choise.
But the planet is so full of anomalies that even the most neutral picture contain something to ponder about, and by some deeper search you easily find highly pecular structures that cannot result from just elementary geological processes. Here is a servey of the most important ones:
Small and great tubes and branched structures
The Martian topology shows many tube-like structures and these often seem to have concentric rings around them with fairly regular intervals. Some of them seem to be composed of a glass-like material. These vary in size from a few inches to great landscape structures. They are often branched, sometimes in a spider-like fashion. The shorter of them can remind of roots. Some are hundreds or thousand meters long and and remind of closed passways, or of those grand scale tubes used on earth to furnish communities with oil, gas or water.
Some of these are probably sand dunes blown together by the wind, others are probably lava tubes, and still others are probably water streams that once froze to ice. But it is difficult to explain all of them this way.
Some areas have a dence occurance of dark branched bodies looking from above like bushes or enormous trees with branches originating from a central body. At a closer look, the greater of them are branched permanent hills with some dark substance at the top of the branches.
The smaller of these tend to come and go by the seasons and may be related to carbon dioxide and water ice freezing and evaoprating. There is speculation that the greater permanent structures originate from material venting out from the ground in combination with processes of erotion. But these explanation are somewhat defective, and by asuming some biological activity you can reach a more complete explanation.
Fossil-like bodies in Martian stones and soil
Martian stones often exhibit small worm-like structures, usually composed of short sections just like earthly worms. When such structures are seen in stones on earth, they most often are fossils, but sometimes the result of geological and chemical processes. Some rocks originating from Mars, but fallen down on Earth, contain microscopic worm-like structures divided into sections. Wnen such structures are seen in Earthly rocks, they usually originate from fosilized microbes or parts of microbes.
Martian rocks contain also a great many small perfectly regular bodies looking like berries on a thick stalk, and the sureface of the bodies generelly has recularly carved lines. They are usually explained as material crystalized from salty solutions sieped out from narrow channels in the rocks. But structures on Earth with that origine are seldome so regularly chaped.
Great regular landscape elements
Areas in the Martian landscape, especilly that called Cydonia, have numerous nearly perfectly shaped pyramids, and eventual shape defects in these structures is easily seen as the result of erotion. These are also often placed in a regular pattern. For example can three of them be placed on a stright line with exactly the same distance.
The same area have a great famous structure looking like a face from distance. As long as there were only distant photos of the structure and it was thought to be really shaped like a face, it was little interesting, since somewhere on a planet you will find some structures that happen to look so just by chance. But now there are short distance photos of the structure that reveal it as an originally perfectly shaped oval pyramid that has partly collaped. And by looking at the collpsed part, one can see that the structure has hollow chambers inside, and the outer shell has collpsed into the chambers.
Things looking like ruins of buildings
Landscape structures that look like eroded fountadions of collapsed buildings are common in certain areas on Mars, and in some instances the structtures even show uneroded flat fasades put together at right angles. In the same areas you will find a lot of blocks of stones with a regular angled shape, looking like construction elements from collapsed buildings.
There are abundant evidence of former lakes, rivers and seas on Mars. By now there is also fairly certain evidence of whater that sieps out from cracks in hills and flow for some time down a slope, which point to the existance of permanently liquid water at some depth in the ground of Mars. Water ice is also common on the planet.
Pecular geological features and processes
The surface of Mars have several holes with a diameter of several hundered meters and so deep that one really do not know how deep into the ground they reach. They were possibly formed when giant lava tubes collapsed, but this explanation is too simple to be complete and lava tubes tend to run horisontally.
Some process is permanently producing methane on the planet. On Earth methane is produced by life forms or by volcanic activity, but Mars does not have any known present volcanic activity.
Nasa behaves strange while presenting Martian material and talking about possible life on Mars
The way Nasa talks about possible former and present life on Mars is in itself an anomaly. They always hold that they are interesting in finding out if Marse once hosted life, and if it still may host microbial life deep at levels of the soil and in cavities. But they always talk about microbial life, when present life is the subject, as if life on Mars has no ability for evolution.
At each mission they send, they say that thay have the aim of finding evidence if Mars formerly had conditions that made life possible. And they always stress the mantra that the expidition is not equipped to find fossil of former living organisms and absolutely not equipped to find organisms living there now. One is easily led to the conclusion that Nasa is hiding something.
If you put all the evidence togeather, including the rather strange behavior of Nasa towards the public, one can draw four tentative conclusions:
- There was nearly certainly former life on Mars. - There is probably life on Mars Now, mostly hidden deep in the soil, and in cracks, caverns and abysses.
- There were possibly intelligent being on Mars at some time that built structures of which we can see eroded remnants.
- Nasa knows about this in fairly great details, but do not reveal all they know to the public.
About NASA's Constellation Program
Constellation Program is a program developed by NASA for new misions around the Earth and missions to the Moon and for developing astronautical vehicles for these missions. The vehicles are also planned to be used for launching modules up in space and to the Moon that then shall be composed together to greater vehicles for manned missions to Mars and other far objects.
The vehicles developed and under developing are planned to replace the space shuttles when these are taken out of service. In some respects, the constellation program goes back to a simpler and more small-scale design of the type that was used in the Apollo program.
The space vehicle battery developed or under
developing consists of the Ares I and Ares V rockets, Orion (also known as the
Crew Exploration Vehicle), Earth Departure Stage and Lunar Surface Access Module
. These craft will be able to conduct a series of missions and assignments in
orbit around the earth and missions to the moon.
Most of the Constellation program's hardware is based on systems originally developed for the space shuttle, but Orion's two-part crew and service module system is heavily inspired by the former Apollo program. Future missions in the Constellation program will therefore make use of techniques to dock spacecraft in Earth orbit and lunar orbit, developed and used in the 1960s.
Space missions in the Constellation Program
Constellation program will include both unmanned and manned missions. It is currently planned 18 missions in the program, including some to the International Space Station, and a minimum of two lunar landings, the two first since the Apollo program ended.
The Ares I rocket
Ares I is a rocket to launch smaller payloads, and to lift the manned
module Orion . It is part of the Constellation program.
Ares I will with high probability to be the rocket that will be used to launch the replacement for the Space Shuttle, the Orion spaceship.
Ares I is constructed as a two-stage rocket powered by rocket-engine J-2X.
The capsule-formed space-ship, Orion, for the person transports will be mounted
in the top. Orion is scheduled to lift up to six people in orbit around the
Earth. Ares I is also planned to act as a pack mule to deliver resources and
supplies to the International Space Station.
At the top of the rocket right under the payload there is a rescue rocket unit that will be engaged if something goes wrong with the launch. It has four nozzles that are directed obliquely downwards. This is to guard against accidents of the kind that happened with the space shuttle Challenger.
Ares I is manufactured by Rocketdyne in the U.S., has a height of 94.2 meters, a diameter of 5.5 meters, a mass of 900 and 000 kilogram two-step process. It has a payload capacity of Low Earth orbit at 25 000 kilogram
The Ares V rocket
Ares V is the NASA's new heavy transport rocket developed through the
Constellation program. Ares V will lift heavy items to the ISS and any modules
for a lunar base. To the manned lunar program Ares V will lift the Manned Lunar
lander before it is coppled to the Orion spaceship in orbit around Earth before
strating the journey towards the Moon.
The rocket will consist of two separate steps. After separation from the first step will the upper stage take over and lift the craft to orbit around the Earth. The second and final step is called the Earth Department Stage in English. This step can lift up to 130 tons.
Ares V is included also in the planning of manned space flight to Mars and planets beyond it.
Ares is manufactured by Rocketdyne in the U.S., has an altitude of 107 meters, a diameter of 8.4 meters, a mass of 3 350 000 kilogram and two step. It has a payload capacity of Low Earth orbit of 130 and a 000 kilogram capacity payload to the moon on 65 000 kilograms.

The Orion Spaceship
Orion, formerly known as the Crew Exploration Vehicle (CEV), is an American spacecraft planned by NASA for use in the Constellation program. Each Orion spacecraft will have a crew from 4 to 6 astronauts, and will be launched by the new Ares I rockets. Both Orion and Ares I are elements of the Constellation program, which plans to send humans back to the moon by 2020 and then on to Mars and other destinations in the Solar System .
31. August 2006 NASA awarded Lockheed Martin the contract to design, develop and
build Orion .
Orion will be launched from the same ramps at Kennedy Space Center, which now launches the Space Shuttle. NASA will use the spacecraft to space flights after the Space Shuttle retirement in 2010. Orion will initially fly trips to the ISS from 2014 through 2015, but will be a key component of missions to the Moon and Mars.
Orion capsule is manned. It looks like the Apollo capsules, but have greater volume and room for four astronauts on a Lunar mission and six on a trip to the ISS.
Orion and the moon landing shoulder will be connected together in Earth orbit before an additional rocket stage bring them up in a speed that makes it possible to break out of Earth's orbit .
The Orinon spaceship connected to a Space
departure stage and a moon
expedition crew lander (A free picture from wikipedia.org)
This is a rocket stage being developped under the constallation program that will be used to depart astronautical vehicles from earth orbits.
It will be launched with the Ares V rocket together with other payload at the top. This other payload can for example be the Lunar Landing module.
Before comming to the final earth orbit it will be seoarated form the Ares V rocket and it will bring itself up the last distance to the stable orbit. There it will be coupled to further modules, for example the Orion spaceship.
Then it will fire once again and bring itself and the payload, for example the Orion and Lunar lander, out of orbit and towards the destination.
The Earth Departer Stage will be driven by combsution of hydrogen with oxygen.
The Lunar Surface Access Module or Altair
This is the planned Moon surface landing vehicle in the constellation program. It will be launched by the Ares V rocket together with the Earth Departure stage. Then it and the Earth departure stage will be connected to the Orion Spaceship launched beforehand with the Ares I rocket. Then it and the Orion will be propelled towards the moon by the Earth Departure Stage.
