"Photographs of the Sea of Crises on the Moon taken by the Lunar Reconnaissance Orbiter show the Soviet lunar landers Luna 20, Luna 23 and Luna 24, which landed on the Moon in the 1970s. In addition to the landers, it is possible to see the tracks made by the Lunokhod lunar rover! The Soviet Lunokhod lunar rover predates the first successful Mars Rover by some 30 years. (Note: Very cool old-style artists' drawings of the Soviet craft at the Wikipedia links above.)"

"A team from Surrey Space Centre has developed a device called a CubeSail, designed to be attached to satellites and rocket stages in order to drag space debris from orbit. CubeSail is a nanosatellite, weighing 3kg (6.6lb), and measures 10cm x 10cm x 30cm. Within its frame is a polymer sheet that unfurls itself once in space. 'The simple deployment mechanism features four metal strips that are wound under tension and will snap into a straight line when let go, pulling the sheet flat in the process.' The overall idea is that 'Residual air molecules still present in the spacecraft's low-Earth orbit will catch the sheet and pull the object out of the sky much faster than is normal.' Sir Martin Sweeting, the chairman of SSTL, who supported the research, said, 'We would be looking to put it on our own satellites and to put it on other people's spacecraft as well. We want this to be a standard, essential bolt-on item for a spacecraft; and that's why it's very important to make it small, because if it's too big it will interfere with the rest of the spacecraft.' The team is also hoping that CubeSail can act as a propulsion system, using 'solar sailing' to help satellites keep their orbits more efficiently."

"Dark matter can't be spotted directly because it doesn't interact with electromagnetic radiation (i.e. it doesn't emit any radiation and reflects no light). However, its gravitational influence on space-time can bend light from its otherwise straight path (a phenomenon known as 'lensing'). Using a sophisticated algorithm to scan a comprehensive Hubble Space Telescope survey of the cosmos, astronomers have plotted a map of 'weak lensing' events. Combining this with red shift measurements from ground-based observatories, they've produced a strikingly colorful 3D map of the structure of dark matter."

Hanger 9 - Cessna 40 ARF, Value Series
In previous section we discussed about major components of radio controlled airplane. In this article will look at further details about Hanger 9 - Cessna 40 ARF, Value Series radio controlled airplane and how each of these components are fixed and controlled. In previous article I mentioned that we need few components to make a airplane. First we need to have structure of the plane, wings and tail. Then we need to have a propeller for your airplane and engine/motor to give power to the propeller. Finally you need to have a mechanisum to control your airplane.
