Voyager 2 34 years after the switch to backup thrusters to continue the flight

Voyager 2 34 years after the switch to backup thrusters to continue the flight.
Voyager probes.

According to the U.S. "Time" magazine reports that the flight 34 years later, the United States Voyager 2 spacecraft on November 4 has the ground engineers instruction by switch to standby attitude control thrusters work to conserve energy to ensure that future missions to continue.
The main task has been completed.
August 1977 and September, NASA's "Voyager 1" and "Voyager 2" was launched flying Jupiter, then to Saturn. According to the plan, if we include the propeller, including the hardware could continue to work, the two detectors will be followed during a visit to Saturn, Uranus and Neptune went. "Voyager 2" was selected one less flight line, in 1989, arrived in the orbit of Neptune. "Voyager 1" is with Saturn gravity, choose the soil - wood line two planets in the solar system in flight.

Completed the two detectors are the primary task, the performance of their engineers constructed beyond the expected. Decades later, their mission continues, fly 330 million miles per year (about 530 million kilometers), and constantly refresh the human space flight made aircraft distance record. In November, NASA engineers announced that they developed new ways to save energy, ensure that "travelers" was the task to continue. That is, they will create a new space flight distance record. Ultimately, the "Voyager" was to fly to the solar system's most remote from the real into the interstellar space. NASA hopes "Voyager" was able to make this dream a reality.

Voyager probe in 1990 from 40 billion miles (about 64 billion km) images of the Earth in space outside the picture. Here the earth is only a dot.
Fly to the edge of the solar system.
No one knows exactly where the end of the solar system, the most reasonable estimate of 14 billion miles from the Sun (about 23 billion kilometers). This is a solar storm of charged particles - the solar wind can reach the most remote. About 14 billion miles between Earth and Pluto ("Voyager" was launched, or when a planet) the maximum distance is about 3 times. Exceeded 14 billion miles in front, "Voyager" was still flying for a long time.
"Game over" moment is approaching. "Voyager 1" is currently about 11 billion miles from Earth (about 18 billion kilometers), "Voyager 2" is currently 9 billion miles from Earth (about 14 billion kilometers). "Voyager 1" was returned in December 2010 data show that charged particles around seems to have stagnated, indicating that it is entering the final transition zone, and then will enter interstellar space. Astronomers of the model does not this "stagnation zone", so they can not predict the thickness of the wall that said particles.

"Voyager" was the project scientist - Eddie Stone said: "The results show that we are close to the boundaries of the solar system, but in the end how close it?"

"Micro-nuclear power plants" to provide energy.
"Voyager" was able to fly so far carried away should be attributed to the isotope temperature generator (hereinafter referred to as RTG), also known as micro-image of nuclear power plants. Pu-238 RTG used as fuel, estimated to be sufficient to ensure that the "Voyager" was flying for 50 years. If the current rate of consumption of fuel, this miniature nuclear power plant will stop functioning in 2025. laptop batteries.

In order to ensure that the "Voyager" was the task to continue, engineers have the command has two detector switches to the backup attitude control thrusters, these thrusters had never used. "Voyager 1" was ordered in 2004, when the main propulsion ignition 353,000 times already. "Voyager 2" was received on November 4 this year, the same command, and the main thruster has firing 318,000 times. Because the work is responsible for the main fuel line heater insulation can be turned off, switch to the attitude control thrusters will save about 12 watts of power consumption.
"Traveler" number has been flying for 34 years, about 12 watts of power at any given time, the total electricity consumption of about 5%, less than three lamp power consumption. It can be said, "Voyager" was developed in human history, the most durable spacecraft, and thus create a space flight distance record. Switch to the thruster command issued from the earth 186,000 miles per second (about 299,000 kilometers per second) transfer speed, reaching the "traveler" number takes 14 hours, the command confirmation message back to Earth and takes 14 hours. November 13, "Voyager 2" was confirmed for another signal to inform the work of normal propulsion engineers, 14 engineers returned only received confirmation.

"Voyager" was carrying gold-plated CD with photos, music and greetings from Earth.

Completely subsided, the "traveler" number will continue to serve as messengers Earth. They carry a 12 inch (30 cm) gold-plated copper discs, phonograph records like the past, there are pictures, music and greetings from Earth.

Why the notebook is always hot? Exposing the notebook cooling defects

Why the notebook is always hot? Exposing the notebook cooling defects.

A long time, notebook because the strictures of the fuselage, at a time when the design has to consider the question of the heat sink. As notebook computer performance fast improve, its internal CPU, and GPU run frequency increasingly fast, corresponding by produced of heat also on increasingly large, how let notebook in small of space within, quickly to internal heat disseminated out, not only is notebook design production manufacturers must to resolved of problem, while, upgrade chip schema, improve energy efficiency and reduced chip calorific value, extended notebook life time, is Intel, and AMD, upstream chip manufacturers of task. Next, we'll take a look at portable design used in cooling technology.

Symptoms for the disease itself: the new Sandy Bridge Framework more conducive to enhance heat dissipation

Thermal comfort of a direct impact on the user's experience, second generation of Intel Core Duo Sandy Bridge architecture intelligent boost 3D gaming performance, HD encoding, decoding performance, is a further milestone for Intel. Using second generation 32nm process technology, the new structure of these second generation high-k metal gate (HKMG) technology manufacturing, advanced technology brings energy efficiency, and reduce heat.

At the same time, second generation core processor with wisdom, according to the different run types dynamically adjust the frequency of the CPU and the GPU, achieve the maximum performance or energy consumption, and join the new power balance algorithm to manage power consumption and heat dissipation and optimal performance. Due to the introduction of a new generation of power-balancing algorithms, new algorithms allow between processor core and the core video cards to have dynamic equilibrium, when detects CPU performance or operation of the system requirements for more powerful graphics performance, TDP resources will be inclined to it for the time being, to this in the heating and power consumption allowed within the scope of providing greater headroom, achieve the best balance of performance requirements and heat sink.

Processor AMD APU series: thermal lift, life advantages

In AMD, including AMD E/C in the early series of ultra low-power processor, AMD processor implemented in recent years APU a series now, using 32nm process manufacturing process and internal code for Llano, a total of three series, number of core quad-core and dual-core, power is divided into and 35W (35W suffix M,45W suffix MX), mainly for laptop and desktop markets. As a result of the new framework, so thermal advantage of lift, battery life is also very obvious.

Regardless of in moved Office, and HD audio play, and 3D game battery life test in the, APU power control and performance performance are appeared out amazing of charm, especially APU accelerated processor of low power run and double graphics switch mode, better of balance has performance and life Zhijian of balance, while in does not sacrifice strong graphics performance of situation Xia, to meet user more of moved Office and audio entertainment using demand, implementation has more long of battery life time, and brings more excellent of fever control.

Cooling solution: tube active cooling fans, keyboards, shell auxiliary cooling

Heat pipe + fan, is a portable basic heat, the biggest advantage of heat pipes fast on a chip pass heat to the heat sink, and then by fans venting heat forced. Only some of the special structure of passive (no fan) products, at present almost all notebooks have adopted this style of active cooling heat sink. And notebook cooling fan with automatic intelligent speed control, depending on the CPU and GPU temperature, or the heat sink temperature and automatically adjust the fan speed to reduce noise effect.

Because of the high calorific value of the CPU and the GPU, so designing better notebooks are usually dual heat pipes, and even three-tube design, you can more quickly on a chip pass heat to the heat sink, and then by fans venting heat forced to effectively reduce internal heat accumulation of the fuselage, improving user hand touch comfort.
By four weeks, opening at the bottom of the cooling vents on the back of the machine, through the cold and hot air flow, remove body heat. At the same time, and cooling vents thermal compatible laptops inside or with special air duct flow design, using heat sink holes and internal structure to create better air circulation, to enhance heat dissipation.

Auxiliary cooling: keyboards, shell is also a thermal window

As the keyboard area occupies most of notebook c area, and area below the keyboard is the fever's largest motherboard, laptop keyboards are in operation with varying degrees of heat. Use bottom boards can also be the keyboard to generate passive conduction of heat, or some thin and light notebook keyboard convection heat sink thermal, tapping the keyboard bounce, complete cold air inflow discharge hot air through the key hole, reached a certain level of cooling. Heat sink while the keyboard fully utilizing resource of the fuselage, but too high a temperature touch, can also affect the user comfort. So they usually left keyboard operation area (left hand) temperature is slightly lower, right (right hand) slightly higher temperatures.

Since notebook internal narrow, so also auxiliary cooling notebook engineers using the shell. In addition to the common appearance of ABS engineering plastic, metal-looking models, the use of metal stronger than plastic thermal conductivity away from, well the auxiliary cooling, because metal fuselage shell has become the largest radiator.

New i5 core graphics Acer 4,750 notebook review.

Since Intel released second generation of core processors have some time, mainstream notebook configurations are currently on the market has been going on for the renewal, core i5 2410M processor with good capacity and relatively low prices in the market in the new notebook has a considerable share. As second generation core processor than compared to previous generation products enhance the most obvious is its integrated graphics capability, so with the core i5 2410M processor and discrete graphics notebook products are also a few is not configured, today we bring you test this Acer 4,750 is such a product.

Since Intel released second generation of core processors have some time, mainstream notebook configurations are currently on the market has been going on for the renewal, core i5 2410M processor with good capacity and relatively low prices in the market in the new notebook has a considerable share. As second generation core processor than compared to previous generation products enhance the most obvious is its integrated graphics capability, so with the core i5 2410M processor and discrete graphics notebook products are also a few is not configured, today we bring you test this Acer 4,750 is such a product.

You can see from the diagram, this Asus A43S part using the keyboard Acer used duckweed-type design, keyboards around the Panel adopts the stamping effects, light gray on the palmrest and keyboard border section in the Visual area forming a clear contrast with the keyboard. The integrated touchpad design, you can avoid foreign bodies out dust, the left and press the moderate resistance and feel better in the actual experience.

The 4,750 provides users with 2 USB2.0 interface, 1 USB3.0 interfaces, 1 HDMI connector, 1 RJ-45 and 1 combo interface, and more than a set of audio, Mike-in-one card reader, you can meet the needs of most users for daily use. In terms of layout, because fewer interfaces, so the layout more rational, larger spacing between two separate USB interfaces will not affect users to plug two USB devices simultaneously. ACER laptop battery.

Storage Accessories section, the Acer 4750G with the 2GB match 500GB DDR3 1333 memory combinations of 5,400 rpm hard drive, 500GB storage capacity is sufficient for most users, and 2GB memory is relatively small for users using the 64bit system has the ability, we propose to add their own memory.

From WIN7 's system for rating this 4,750 's final score is 5.5, desktop graphic performance score lowest in the various subprojects, but considering that the machine is not configured for a video card, the results we expected. Processor in other child subkeys 6.9 points was the highest individual points and 6.1 gaming graphics score indicates that the machine can host some low-end 3D games. Score from memory and hard drive, its relatively low memory child also scored, we also propose to have the ability to users to consider adding a stick of RAM.

Call of duty 7 as a high demand for hardware of the game, representing the current application of large 3D gaming needs, often were also more likely to help us distinguish between a notebook gaming performance you can achieve what level. From a test video you can see above, only about 10 frames when tested in the machine, this shows that you want to use the integrated video card to run such a load higher 3D gaming is very difficult.

Battery, actual power consumption and heat test

ACER battery.

We mainly use Mobile Mark2007 software multimedia production is mainly used to simulate the daily Office and thorough examination of life. MobileMark 2007 is based on real-Notebook battery life and performance evaluation software. It supports Windows Vista/XP 64bit/32bit version (Professional/Home). It has three modes of testing: Productivity module, and DVD module and the Reader module, called Adobe AcrobatReader, respectively 7, Adobe Illustrator CS2, Adobe Photoshop CS2, Apple Quicktime 7.1, Intervideo WinDVD 8, Macromedia Flash 8、Microsoft Office 2003 Pro、Microsoft Project 2003、Winzip 10.0。 ACER LAPTOP BATTERIES.

In testing, we turn off the screensaver, hibernation, and set both the battery and the system for maximum performance mode as a basis for testing, you can see from the image above this Acer 4,750 notebook performance in tests to provide users with 399 minutes of battery life, the battery life in Mobile Office has been able to meet most people's needs. In addition, taking into account in testing the high pressure machine, and generally do not appear in the practical application of continuous high-load applications, plus user or power management measures through effective controls and other factors, so we have reason to believe that the actual battery life should be a better application performance.

Actual power consumption tests.

We also tested the actual power consumption of the product, we tested a total power consumption of this product in the three States. We use intelligent digital multimeter UNI-T UT71E as test equipment, namely determination of power but not on State of the connection (non-rechargeable), system startup is complete, within 5 minutes of no action, but does not sleep (non-rechargeable), and system startup is complete, processor load, disk at maximum throughput (non-rechargeable) lower power consumption.

In the three test conditions which 4,750 power 0.3W, and 13.8W, respectively, this test data than usual slightly below notebooks configured with discrete graphics, this shows that when a user is using the machine needed to pay for electricity costs are lower.

Heat tests.

In this session, we use a FLUKE Ti25 infrared imaging equipment on the calorific value of the product was a test, test measurement of portable c side, bottom and the heat sink temperature. In testing, we used the EVEREST software, select the System Stability Test, check all the items, 15 minutes after the test, and we measure indoor temperature, to enable readers to test the data with an intuitive understanding.

From above test figure in the can see, regardless of is notebook of keyboard surface also is end surface of temperature are has over has human of normal temperature, but due to temperature difference does not is large and fever regional area relative larger, so in using in the does not will to people a points temperature high of feeling, but will was fuselage overall comparison warm, such of performance in using in the also does not let people was special does not apply.

In the context of notebook sales there is fierce competition, the price of a product to a large extent about the user's purchase, the Acer 4,750 to ensure a solid body and other hardware, and machine performance at the same time, early have managed to keep the price at 4K, I believe this is attractive for users who attach importance to price. In respect of the overall machine hardware configurations, we recommend users to add 1 2GB memory for better overall performance.

We mentioned before which came with a core i5 2410M set explicit can have basically reached the entry-level standard of independence, and from software testing results and it is, 3D Mark Vantage test 7,761 compared to our more familiar with the previous generation GPU performance entry level alone have better performance. From the point of view of practical applications, this product in the daily Office, audio play and has a good low-end 3D gaming performance, and if the user wants to run some medium 3D games you need to sacrifice the quality of games to ensure a certain level of fluency.

Appearance of new style exquisite and stable coexistence

HP g4-1016TX with a new look and style design, metallic look elegant and calm. Although made of engineering plastic material to shell, but benefit from the performance of the top cover surface treatment technology, makes the whole product grades look quite upscale. Fuselage corners designed with both a smooth transition, we received the product the fuselage color scheme uses a quiet introverted metal grey and reflective black with, and the color effect of surface treatment products combined with a look in fashion as those reported by little stable.

HP g4-1016TX top cover surface using the class piano paint treatments, smooth surface is in line with popular trends, although you cannot avoid dirt contamination such as fingerprints, but metal gray ground color can have these stains appear less conspicuous.

HP g4-1016TX and borders of the screen using the mirror screen + combination of matte border, this combination in a complex environment for the Visual effects of light to below the mirror screen + combination of piano lacquer border, this combination ensures that users experience. Border central location on the screen you can see a high speed camera, comparing with common cameras, high speed cameras can in poor lighting conditions when giving users better take effect.

HP g4-1016TX keyboard design follows the top cover surface processing means, surrounded by a border of black metal grey panels, and the borders around the keyboard area of the black and formed the echo.
HP g4-1016TX keyboard also uses a separate design, press the surface using a dull black scrub, press feel relatively generic. Touchpad with integrated touchpad is very large, metal stamping effects of particles on the surface, can enhance the use of the handle.

In terms of interfaces and scalability, the HP g4-1016TX laptop has 3 USB2.0 interface, 1 HDMI connector, 1 x d-Sub connector, 1 x audio, Mike RJ-45 and 1 group combo interface, also has a built-in SD/MMC/MS/xD reader, you can meet the needs of most users for daily use, but for users who frequently need to copy large amounts of data, USB2.0 interface speed can make them for a long period of time could not make a 640GB hard disk full of determination.

HP g4-1016TX provides users with a hard drive and memory upgrades possible, dual socket configurations allow users to upgrade costs can be effectively reduced. Additionally equipped with DVD burning optical drive support optical carving technology to facilitate user-make your own disc cover.
