Topic: Goldstone Deep Space Communicatios Complex
After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined. ![]() This image of asteroid Apophis was recorded by radio antennas at the Deep Space Network’s Goldstone complex in California and the Green Bank Telescope in West Virginia. The asteroid was 10.6 million miles (17 million kilometers) away, and each pixel has a resolution of 127 feet (38.75 meters).

NASA’s Opportunity Mars Rover Mission EndsNASA Headquarters
The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover’s final communication was received June 10th. ![]() The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004), by the rover’s front hazard-avoidance camera as the rover moved farther into Endurance Crater in the Meridiani Planum region of Mars.

NASA’s twin Voyager Spacecraft helped improve CommunicationsWritten by Andrew Good
The mission’s impact is still visible in California’s Mojave Desert. There, at NASA’s Goldstone Deep Space Communications Complex, the arcs of antenna dishes peek out over craggy hilltops. Goldstone was the first place where the two Voyagers started to change the landscape. The farther they traveled, the bigger these dishes needed to be so they could send and receive radio waves necessary to track and communicate with the probes. ![]() In order to “talk” with the distant Voyager spacecraft, NASA had to leap forward in space communication technology. In the image above, a 64-meter-wide antenna dish in Goldstone, Calif. is expanded to 70 meters. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Goldstone Solar System Radar captures images of Asteroid’s flyby of EarthWritten by DC Agle
The images reveal a peanut-shaped asteroid that rotates about once every five hours. The images have resolutions as fine as 25 feet (7.5 meters) per pixel. Asteroid 2014 JO25 was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona — a project of NASA’s Near-Earth Objects Observations Program in collaboration with the University of Arizona. ![]() This composite of 30 images of asteroid 2014 JO25 was generated with radar data collected using NASA’s Goldstone Solar System Radar in California’s Mojave Desert.

NASA uses new application of Radar to find missing Spacecraft orbiting the MoonWritten by DC Agle
However, a new technological application of interplanetary radar pioneered by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, has successfully located spacecraft orbiting the moon — one active, and one dormant. This new technique could assist planners of future moon missions. ![]() DSS-14 is NASA’s 70-meter (230-foot) antenna located at the Goldstone Deep Space Communications Complex in California. It is known as the “Mars Antenna” as it was first to receive signals from the first spacecraft to closely observe Mars, Mariner 4, on March 18, 1966.

NASA’s Goldstone Solar System Radar images Asteroid as it passes by EarthWritten by DC Agle
“The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders,” said Lance Benner of NASA’s Jet Propulsion Laboratory in Pasadena, California, who leads the agency’s asteroid radar research program. ![]() This composite of 25 images of asteroid 2017 BQ6 was generated with radar data collected using NASA’s Goldstone Solar System Radar in California’s Mojave Desert.
