  • you can go into the facility, you can go into some of the large areas there, like the Vehicle Assembly Building. You can go down to the launch pad and actually go up several floors of the launch pad and see where the astronauts would walk and where they would go as they were boarding the shuttle
  • actually got to take a snapshot of these structures and these systems in place before all those transitions happened
  • Many of those facilities are going to be decommissioned or converted to different uses
  • So the opportunity to kind of capture that moment in Street View and preserve it, and make it accessible to people around the world, is I think really valuable and important

Mystery: U.S X-37B space plane has been in orbit for over a year | Mail Online - 0 views

  • Last May, amateur astronomers were able to detect the orbital pattern of the first X-37B which included flyovers of North Korea, Iraq, Iran, Pakistan and Afghanistan, heightening the suspicion that the vehicle was being used for surveillance.
  • Other industry analysts have speculated that the Air Force is just making use of the X-37B’s amazing fuel efficiency and keeping it in space for as long as possible to show off its credentials and protect it from budget cuts.

  • Glenn in orbit
  • In 1962, John Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first U.S. manned orbital mission. Launched from Kennedy Space Center, Florida, he completed three-orbits around the earth, at a maximum altitude of approx. 162 miles and an orbital velocity of approx. 17,500 mph. He spotted Perth, Australia, when that city's residents greeted him by switching on their house lights in unison. A four-cent U.S. stamp was put on sale the same day, making it the first U.S. stamp issued on the day of the event it commemorated. Glenn returned to space 36 years later, making 134 more orbits as a crew member of the space shuttle Discovery (29 Oct - 7 Nov 1998) for investigations on space flight and the aging process.
  • In 1986, the Soviet Union launched into orbit Mir, a new space station. Mir, the Russian word for peace, had six docking ports and special laboratories for scientific research. Weeks later, a veteran crew was sent to man the 56-ft-long and 13.6-ft wide station. The core module provided living quarters for the cosmonauts: galley/table, cooking elements and storage, individual crew cabins and personal hygiene area. They also had a working compartment for monitoring and commanding the core systems supported by an electric power system, thermal control system, computer systems, environmental control and life support, communications and tracking systems. Five additional modules were launched between Mar 1987 and April 1996

  • In 1937, the first a successful automobile-airplane combination was complete and ready for testing.The first flight took place the next day, 21 Feb 1937. Built by the Westerman Arrowplane Corporation of Santa Monica, Cal., the vehicle was dubbed the Arrowbile, and claimed a top air-speed of 120 mph and 70 mph on a highway. Designed by aeroengineer Waldo Dean Waterman (1894-1976), it evolved from the prototype Arrowplane, a project to design a simple, easy to fly, low cost airplane. The Studebaker Corporation, which supplied the 100 hp engines, eventually took delivery of five Arrowbiles

  • Hubble Space Telescope
  • In 1990, the $2.5 billion Hubble Space Telescope was deployed in space from the Space Shuttle Discovery into an orbit 381 miles above Earth. It was the first major orbiting observatory, named in honour of American astronomer, Edwin Powell Hubble. It was seven years behind schedule and nearly $2 billion over budget. In orbit, the 94.5-in primary mirror was found to be flawed, giving blurred images and reduced ability to see distant stars. However, correcting optics were successfully installed in 25 Dec 1993. The telescope 43-ft x 14-ft telescope now provides images with a clarity otherwise impossible due to the effect of the earth's atmosphere. Instrument packages capture across the electromagnetic spectrum.

  • The heat shield measures 16.5 feet in diameter
  • It is constructed from a single seamless piece of Avcoat ablator
  • The ablative material will wear away as it heats up during the capsules atmospheric re-entry thereby preventing the 4000 degree F heat from being transferred to the rest of the capsule
  • The Delta IV Heavy is the only rocket with sufficient thrust to launch the Orion EFT-1 capsule and its attached upper stage to its intended orbit of 3600 miles altitude above Earth
  • 15 times higher than the International Space Station (ISS) and farther than any human spacecraft has journeyed in 40 years
  • At the conclusion of the two-orbit, four- hour EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
  • “That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations
  • The big reason to get to those high speeds during EFT-1 is to be able to test out the thermal protection system
