The precise distance between the two spacecraft can be accurately measured using radio interferometry and tracking beacons with ultra-stable oscillators.
By precisely measuring changes in the distance between the twin orbiting spacecraft as they traverse the moon’s gravitational field, scientists expect to create a lunar gravity model up to 1,000 times more accurate than previous models.
Wallpaper, once the favorite daughter of interior design, is now more like the ugly stepchild.
The late 20th century took a toll on the decorating medium that has roots in the early 1700s, bringing far too much paisley and visions of mustard yellow to the dens and foyers of homes past.
The quality and beauty of the Chinese papers far outshone anything produced in France, wallpaper’s country of origin.
The earliest recorded wallpaper in Europe dates from 1481, when a manuscript painter named Jean Bourdichon created 50 rolls of hand- painted paper in sky blue, decorated with a host of angels and mounted on panels, for King Louis XI of France, who carted them around to his various castles to brighten up draughty rooms.
31; GRAIL-B will enter lunar orbit the following day.
GRAIL’s 90-day scientific mapping mission will begin in March 2012.
But for the most part, we paint and we stencil, so the practice of pasting paper onto our kitchen and dining room walls has appropriately faded into design history.Since 2002, the inception of the project, the wallpaper collection has grown to over 6,000 pieces, which conservators at the Historic New England are tasked with repairing, correcting and treating for posterity.The online database makes available a collection that covers three centuries, including pieces imported to the United States in the early days to William Morris designs to the real deal -- retro vinyl masterpieces.Griswold Professor of Geophysics and Planetary Science at MIT — becomes the first woman to lead a planetary spacecraft mission.Following the launch of the twin GRAIL spacecraft and a four-month journey, GRAIL-A is scheduled to enter orbit around the moon Dec.
