Mars 1 crew voyage

Permanent settlement allows Mars One to use technology that is not substantially different from existing systems. The hardware specifically needed for this mission still needs to be designed, built, and tested extensively but the technology already exists. Mars One is not an aerospace company and will not design or manufacture mission hardware. All equipment will be developed by third party suppliers and integrated in their established facilities.

Mars One has visited major aerospace companies around the world to discuss the requirements, budget, and timelines with their engineers and business developers. The current mission plan was composed on the basis of the feedback received in these meetings. These are preliminary results that need to be improved by conceptual design studies, which Mars One will contract a supplier for. The first studies have already been awarded to a supplier.

The mission is comprised of the following primary hardware components.

Mars Landing Module: Mars One will secure the landing modules from one of the experienced suppliers in the world, for example Lockheed Martin. Similar landers will be equipped to perform different functions.

1. Carrying Life Support Units that generate energy, water and breathable air for the settlement.
2. Carrying Supply Unit with food, solar panels, spare parts and other components.
3. Carrying Living Units that are outfitted with deployable inflatable habitats.
4. Carrying Humans to the surface of Mars
5. Carrying Rovers to the surface of Mars

Rovers: Two rovers will be sent to Mars to set up the outpost before the humans arrive. One of them will explore the surface of Mars in search of the most suitable location for the settlement, transport of large hardware components, and the general assembly. Mars One’s rover supplier will determine the exact rover strategy; it is possible that instead of one large rover, multiple smaller rovers will be sent. For example, a main rover accompanied by a trailer system used for transporting the landing capsules.

Mars Suit: All astronauts must wear their Mars suits when exposed to the Mars atmosphere. Like those used by the Apollo astronauts on the Moon, Mars suits protect astronauts from extreme temperatures and the very thin, non-breathable atmosphere.

Communications System: The communications system will consist of two communications satellites and Earth ground stations. It will transmit data from Mars to Earth and back.

Mars Transit Vehicle: The transit vehicle will consist of two propellant stages, a landing module, and a transit habitat. The landing module will be similar to the ones used for the unmanned Mars missions. The crew will travel through space for approximately seven or eight months, depending on the year of departure, which is much shorter than many MIR Station missions and even shorter than the new one year shifts in the ISS. The transit habitat will be a small space station when compared to the large ISS module. The water tanks and other storage will be used to create a radiation shelter that will also function as crew sleeping quarters. When the crew arrives on Mars, they will descend to the Mars surface in their Mars suits in the landing module. They will then leave the transit habitat behind because it is too large and too heavy to land. This means that the transit habitat needs a lifetime of only the duration of the journey to Mars, which is much shorter than ISS modules.

Launcher: Mars One will choose the right launch supplier from existing, experienced companies.

Magnetics Resonance Imaging

Magnetic resonance imaging (MRI) is the diagnostic tool that currently offers the most sensitive non-invasive way of imaging the brain, spinal cord, or other areas of the body. It is the preferred imaging method to help establish a diagnosis of MS and to monitor the course of the disease. MRI has made it possible to visualize and understand much more about the underlying pathology of the disease.

Benefits

• MRI is a noninvasive imaging technique that does not involve exposure to ionizing radiation.
• MR images of the soft-tissue structures of the body—such as the heart, liver and many other organs— is more likely in some instances to identify and accurately characterize diseases than other imaging methods.

How it works

Unlike a computed tomography (CT) scan or conventional X-ray, MRI does not use radiation. Instead, MRI uses magnetic fields and radio waves to measure the relative water content in tissues — both normal tissue and abnormal — in the body . MRI works in the following way:

1. A very strong magnetic field causes a small percentage of the hydrogen protons in water molecules to line up in the direction of the magnetic field. The percentage lined up is small, but large enough to give a strong signal for imaging.
2. Once the hydrogen protons have been lined up, radio waves and some additional but weaker magnetic fields are used to knock them out of line.
3. When the radio waves are stopped, the protons relax back into line. As they relax, the protons release resonance signals that are transmitted to a computer.

The Inventor of MRI is Raymond Vahan Damadian

Age Defying Cosmetics

No one wants to look old and this is a universal phenomenon. We all keep striving for means to defy age and look young. Luckily some cosmetic procedures have made it possible. So there is laser hair removal, breast augmentation and rhinoplasty for young adults, as a proportionate body and a perfect face is all they want. People who fall in the age group 35-50 can get injectables to slow down their signs of aging. Liposuction and tummy tuck is a popular procedure in this age group. People living the next decade and a half can get face lifts, eyelid surgery and brow lifts. 

-It makes your face younger than your now age

HYBRID CARS

The auto industry has the technology to address these concerns. It's the hybrid car. There are a lot of hybrid models on the market these days, and most automobile manufacturers have announced plans to manufacture their own versions.

How does a hybrid automobile work? What goes on under the hood to give you 20 or 30 more miles per gallon than the standard automobile? And does it pollute less just because it gets better gas mileage? In this article, we'll help you understand how this technology works, and we'll even give you some tips on how to drive a hybrid car for maximum efficiency.
Porsche Chief Engineer, Wolfgang Duerheimer, explains to California Governor Arnold Schwarzenegger that the Lohner-Porsche was the first advanced electric car and the technological star of the 1900 Paris Auto Show.
