"We need to understandwhat is causing this if we are contemplating putting additional scientificequipment on the moon. "Near full moon, the strength of the returning lightdecreases by a factor of ten," Murphy said. The researchers found that the laser light they bounce offreflectors on the lunar surface is fainter than expected and dims even morewhenever the moon is full. Murphy and his colleagues found in a study published this monththat lunar dust may be obscuring the reflectorson the moon. "Lunokhod 1, by virtue of its location, would providethe best leverage for understanding the liquid lunar core, and for producing anaccurate estimate of the position of the center of the moon ? which is ofparamount importance in mapping out the orbit and putting Einstein's gravity toa test," Murphy stated. Reflectors are such a simple piece of equipment, but they go a long way to improve your photos. The discovery of Lunokhod 1 will greatly improve uponstudies of the moon and its composition. A reflector is a surface that can reflect light. "In fact, the signal is so surprisingly strong that therover could not be in anything but a level parking spot with its commanded rollon the lunar surface deliberately oriented toward the Earth." "Not only now do we know that Lunokhod 1 is there, wealso know that it is parked perfectly so that its reflector faces Earth,"Murphy explained. Prior to this discovery, many scientists had speculated thatthe Lunokhod 1 rover might have fallen into a crater or parked badly, with itsreflector not facing Earth, which would have prevented it from being located bylaser pulses. It's got a lot to say after almost 40 years of silence." "We quickly verified the signal to be real and found itto be surprisingly bright: at least five times brighter than the other Sovietreflector, on the Lunokhod2 rover, to which we routinely send laser pulses," Murphy said."The best signal we've seen from Lunokhod 2 in several years of effort is 750return photons, but we got about 2,000 photons from Lunokhod 1 on our firsttry. The return signal from the reflector was measured as acollection of photons, or individual particles of laser light. ![]() In the coming months, it will be possible for scientists toestablish the reflector's coordinates with even greater precision, Murphy said. They then made a second observation less than 30minutes later that allowed the team to triangulate the reflector's latitude andlongitude on the moon to within 10 meters (0.006 miles). The team was able to find the longlost Lunokhod 1 reflector and pinpointed its distance from Earth to withinone centimeter (0.4 inches). On April 22, Murphy's team sent pulses of laser light fromthe 3.5 meter telescope at the Apache Point Observatory in New Mexico, zeroingin on the target coordinates provided by the LRO images. Untilnow, the precise location of the rover's reflector had been unknown. Thecamera team identified the rover as a sunlit speck on the image, which turnedout to be miles away from where Murphy and his team had been searching. The breakthrough came last month, when the high-resolutioncamera on NASA's LunarReconnaissance Orbiter (LRO) obtained images of the landing site. Translucent umbrellas are perfect to create soft light when you’re very close to your subject.Murphy and his team occasionally looked for the Lunokhod 1reflector over the last two years, but had no luck finding it until recently. The shoot-through umbrellas (translucent) are used to shoot light through and they diffuse and soften the light by reducing contrast. The White reflects a more natural, softer light. When it comes to fabric, the Silver creates a very crisp, direct light with more contrast and a high light output, a little like the light you’d get from a hard reflector. ![]() Think of it like this – the larger the umbrella the softer the light will be. The size affects the softness and spread of light. The umbrellas comes in sizes from 85 cm to 165 cm. The Umbrella Deep, ideal when you want to control the light more precisely, and the Umbrella Shallow that are perfect for wide and even light spread. Umbrellas are the backbone of many photographers’ toolboxes, understandably so, because they are easy to work with and ideal to bring on location. ![]()
