Whitesand Bay (Cornish: Porth Senan, meaning cove at Sennen) is a wide sandy bay near Land's End in west Cornwall, England, United Kingdom. It stretches for one mile between the headlands of Pedn-mên-du and Aire Point. and contains the village of Sennen Cove.[1] It is also a landing point for the Atlantic Crossing 1 international telecommunications cable.
Whitesand Bay beach is popular with surfers. At high tide, the beach is divided in two: Sennen Cove beach to the south (more popular for its size, facilities and surf schools), and Gwynver beach to the north (popular for its typically better surfing waves and walking distance of Trevedra Farm campsite). At the south end, at Sennen Cove, there are toilet facilities, a surf shop, a restaurant, and two car parks, one in a large field above the cliff, and another beside the beach. Dogs are banned on the beach from Easter Day to 1 October every year.[2] The South West Coast Path runs along the dunes behind the beach.[3]

Projector Sound Projector Sound Beep On December 24, 1968, Apollo 8 captured the historic photo known as “Earthrise”. However, it would take several days for the rest of the world to see this awe-inspiring image. Today, NASA has the capability to send hundreds of “earthrise” like photos from the moon every second using lasers. The Lunar Atmosphere and Dust Environment Explorer, or LADEE, will investigate the Moon’s fragile atmosphere to enhance our knowledge of Earth’s nearest neighbor. LLCD, the Lunar Laser Communication Demonstration, will hitch a ride aboard LADEE to lunar orbit. Using a small and lightweight telescope, LLCD will transmit hundreds of millions of laser pulses each second to one of three stations on the Earth….. Each of which was chosen for it’s cloud-free skies. To begin data transmission, the space and ground terminals must first locate each other. This process begins when the ground terminal scans LADEE’s path to illuminate the spacecraft. LLCD senses the flash from the ground and points its beam back to the source. The ground terminal acquires the beam from space and establishes a communication link. With contact established and alignment locked, hundreds of millions of data bits begin to flow between the two terminals every second. Music Back on Earth, the ground terminal receives the laser pulses through an array of telescopes that focus the weak signals onto ultra-sensitive detectors. These detectors count the individual signal photons from the terminal at the Moon, and turn them into data bits at revolutionary download speeds. In the future NASA could download finer images, hundreds of 3-D HD video streams, and could even one day enable “telepresence” at the Moon and beyond for human explorers still on Earth. Together LLCD and LADEE will take the next step in expanding NASA’s space communication capabilities while renewing our sense of discovery about the Moon and the universe.

History
Perkin Warbeck landed here at the start of the Second Cornish Uprising of 1497.[4] The bay lends its name to the Bay class frigate HMS Whitesand Bay.[citation needed].
Natural history
The west facing bay is backed by a 38 hectares (94 acres) dune system which has developed from a limited supply of sand trapped within the shelter of the headlands, Pedn-mên-du (in the south) and Aire Point. The dunes contain the only British population of the shield bug Geotomus punctulatus which was first recorded here in 1864.[5][6] G. punctulatus is a southern European species and associated with sparsely vegetated areas of loose sand and feeds on lady's bedstraw (Galium verum). Another rarity is Emblethis griseus a seed-eating bug associated with marram grass (Ammophila arenaria), common stork’s-bill (Erodium cicutarium), spurges (Euphorbia species) and sparse grassland. Never numerous here, it is also recorded in the Isles of Scilly and Kent.[7]
