Blue Marble: Next Generation provides an updated version of the seasonal changes dataset. Months and then the depletion of it during the summer months. The mostĭramatic change is the expansion of the snow cover during the winter The monthly evolution allows audiences to see theĬhanging appearance of the Earth due to the season changes. This monthly evolution is the seasonal blue marble. Marble without clouds is also available in monthly composites the entire The standard Blue Marble isĪ year long composite to show an average view of the earth. The characteristics of the changing Earth. Geological Survey's Earth ResourcesĪdditional Blue Marble datasets are available to highlight some of The shading of the land was done using aĭataset compiled by the U.S. White and the lands varying from green to brown. The shading is true color with the oceans shades of blue, the clouds The first two days of data were collected in the visible wavelength and the third day was needed to get a view of the clouds over the poles using thermal infrared imagery. The cloud image is a composite of three days worth of data. This could not be done in a single day or even a week because on any given day clouds are blocking a significant portion of the surface. The background image of the land and oceans was created using data from June through September of 2001. Most of the information came from NASA's MODIS, the Moderate Resolution Imaging Spectroradiometer, which is attached to the Terra satellite 435 miles above Earth. NASA is responsible for this dataset made from a compilation of satellite images throughout 2001. exactly when we move our hand beyond The Prism we could see it in the different colors.The Blue Marble is an incredibly detailed, true-color depiction of Therefor during moon moves around the earth will passes in a different areas of The Sun light different FREQUENCIES zones thus once the moon will appear as Red then Blue etc. The main reason is THE LIGHT DIFFERENT PHNOMENON and perhaps this eclipse is not 100% Eclipse, maybe 99% eclipse, where 1% no eclipse is sufficient to pass Sun’s Rays to creates a light different phenomenon above the Moon.īecause THE LIGHT DIFFERENT PHNOMENON defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle that mean passing the light at a parallel dimension of the material object therefor the different phenomenon occurs due to the attraction between light’s Photons and The Material of The Object that stands nearby the direction of the light, and the value of THE LIGHT DIFFERENT PHNOMENON depends upon the wavelength of the light. Thank you for sharing these videos and images for The Super Blue Blood Moon of the total lunar eclipse, I would kindly share may thoughts to explain the physics reasons beyond changing the color of the Moon during this Eclipse. THE LIGHT DIFFERENT PHNOMENON IN TODAY`S MOON ECLIPSE They’ll stow a pair of latching end effectors, or robotic hands, which had been detached from the Canadarm2 on two previous spacewalks, the first on Oct. when Vande Hei and Kanai exit the station to continue robotics maintenance on the Canadarm2. The second spacewalk is set to take place Feb. They’ll work outside for about 6.5 hours of maintenance on the Russian side of the orbital laboratory. Doctors on the ground remotely assisted the astronauts viewing their eyes in real time.Ĭosmonauts Alexander Misurkin and Anton Shkaplerov donned their Orlan spacesuits today to ensure a good fit and check for pressure leaks ahead of a spacewalk scheduled to start Friday at 10:30 a.m. Then Tingle joined Acaba and Vande Hei afterward for more eye checks using a fundoscope. Tingle and Kanai first swapped roles as Crew Medical Officer checking each other’s eyes today using optical coherence tomography. The study is researching how algorithms and sensors may help determine relative positions and velocities between spacecraft.īoth astronauts also joined Flight Engineers Scott Tingle and Norishige Kanai for eye exams during the afternoon. NASA astronauts Joe Acaba and Mark Vande Hei brought out a pair of tiny satellites, also known as SPHERES (Synchronized Position Hold, Engage, Reorient, Experimental Satellites), for a run of the SmoothNAV experiment today. 2 spacewalk with cosmonauts Alexander Misurkin and Anton Shkaplerov.Īs the International Space Program gets ready for a pair of spacewalks in February, the Expedition 54 crew was busy setting up a pair of experimental internal satellites and conducting vision checks today. The spacesuits will be worn during a Feb. A pair of empty Russian Orlan spacesuits are pictured inside the airlock of the Pirs docking compartment.
