At right is NASA Public Affairs Officer Gregory Harland. They also discussed the future steps the program will take to certify crew transportation systems for missions to the International Space Station. The program is working toward the next phase of certification, which will be called Commercial Crew Transportation Capability, or CCtCap. That phase will include a joint test concept in which NASA astronauts will play a role in flight testing the systems. To learn more about CCP, visit www.nasa.gov/commercialcrew.

CAPE CANAVERAL, Fla. – Jim Adams, deputy director of planetary science at NASA Headquarters in Washington, speaks to a group of Tweetup participants at the Kennedy Space Center Visitor Complex in Florida during prelaunch activities for the agency’s Gravity Recovery and Interior Laboratory (GRAIL) mission. Participants toured NASA’s Kennedy Space Center and got a close-up view of Space Launch Complex 17B at Cape Canaveral Air Force Station. The tweeters will share their experiences with followers through the social networking site Twitter. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon’s gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon’s crust and mantle and will help answer fundamental questions about the moon’s internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon’s gravity field so completely that future lunar vehicles can safely navigate anywhere on the moon’s surface. Launch is scheduled for 8:37:06 a.m. EDT Sept. 8.

CAPE CANAVERAL, Fla. – Dan Dumbacher, NASA deputy associate administrator for Exploration Systems Development, addresses the audience assembled in Kennedy Space Center's Operations and Checkout Building high bay for an event marking the arrival of NASA's first space-bound Orion capsule in Florida. Slated for Exploration Flight Test-1, an uncrewed mission planned for 2014, the capsule will travel farther into space than any human spacecraft has gone in more than 40 years. The capsule was shipped to Kennedy from NASA's Michoud Assembly Facility in New Orleans where the crew module pressure vessel was built. The Orion production team will prepare the module for flight at Kennedy by installing heat-shielding thermal protection systems, avionics and other subsystems.

CAPE CANAVERAL, Fla. --- After offloading external tank No. 128 from the Pegasus barge in the Launch Complex 39 Area at NASA's Kennedy Space Center, the tow vehicle begins moving it to the Vehicle Assembly Building, in the background. The tank is scheduled for space shuttle Discovery's STS-124 mission. On the STS-124 mission, Discovery will transport the Kibo Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System to the International Space Station.

Echo - A Passive Communications Satellite

description

Summary

Echo, NASA's first communications satellite, was a passive spacecraft based on a balloon design created by an engineer at NASA's Langley Research Center. Made of Mylar, the satellite measured 100 feet (30 meters) in diameter. Once in orbit, residual air inside the balloon expanded, and the balloon began its task of reflecting radio transmissions from one ground station back to another. Echo satellites, like this one, generated a lot of interest because they could be seen with the naked eye from the ground as they passed overhead. Echo 1 was launch August 12, 1960...Image # : 61-E2-1
