The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2. ![]() Crews conduct critical upgrades and repairs to the 70-meter-wide (230-foot-wide) radio antenna Deep Space Station 43 in Canberra, Australia. In this image, one of the antenna’s white feed cones (which house portions of the antenna receivers) is being moved by a crane.

Plunge into Saturn ends NASA’s Cassini Spacecraft’s groundbreaking missionWritten by Dwayne Brown / Laurie Cantillo
“This is the final chapter of an amazing mission, but it’s also a new beginning,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington. ![]() Saturn’s active, ocean-bearing moon Enceladus sinks behind the giant planet in a farewell portrait from NASA’s Cassini spacecraft. This view of Enceladus was taken by NASA’s Cassini spacecraft on Sept. 13, 2017. It is among the last images Cassini sent back.

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 Juno spacecraft completes burn, now in Jupiter OrbitWritten by DC Agle
“Independence Day always is something to celebrate, but today we can add to America’s birthday another reason to cheer — Juno is at Jupiter,” said NASA Administrator Charlie Bolden. “And what is more American than a NASA mission going boldly where no spacecraft has gone before? With Juno, we will investigate the unknowns of Jupiter’s massive radiation belts to delve deep into not only the planet’s interior, but into how Jupiter was born and how our entire solar system evolved.” ![]() This illustration depicts NASA’s Juno spacecraft successfully entering Jupiter’s orbit.

NASA gives explanation for extra second on June 30th, 2015Written by Elizabeth Landau
“Earth’s rotation is gradually slowing down a bit, so leap seconds are a way to account for that,” said Daniel MacMillan of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Strictly speaking, a day lasts 86,400 seconds. That is the case, according to the time standard that people use in their daily lives – Coordinated Universal Time, or UTC. UTC is “atomic time” – the duration of one second is based on extremely predictable electromagnetic transitions in atoms of cesium. These transitions are so reliable that the cesium clock is accurate to one second in 1,400,000 years. ![]() A flower clock is seen in the Jardin Anglais, Geneva, Switzerland.

NASA’s New Horizons Spacecraft arrives at PlutoWritten by Tony Phillips
Operators at the Johns Hopkins University Applied Physics Laboratory in Laurel, MD, confirmed at 9:53pm (EST) that New Horizons, operating on pre-programmed computer commands, had switched from hibernation to “active” mode. Moving at light speed, the radio signal from New Horizons – currently more than 2.9 billion miles from Earth, and just over 162 million miles from Pluto – needed four hours and 26 minutes to reach NASA’s Deep Space Network station in Canberra, Australia. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft enters Mars OrbitWritten by Tony Phillips
“As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden. “It also will better inform a future mission to send humans to the Red Planet in the 2030s.” «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Science Laboratory Launch MilestonesWritten by Whitney Clavin
The spacecraft, which will arrive at Mars in August 2012, is equipped with the most advanced rover ever to land on another planet. Named Curiosity, the rover will investigate whether the landing region has had environmental conditions favorable for supporting microbial life, and favorable for preserving clues about whether life existed. ![]() This artist's concept depicts the rover Curiosity, of NASA's Mars Science Laboratory mission, as it uses its Chemistry and Camera (ChemCam) instrument to investigate the composition of a rock surface. ChemCam fires laser pulses at a target and views the resulting spark with a telescope and spectrometers to identify chemical elements. The laser is actually in an invisible infrared wavelength, but is shown here as visible red light for purposes of illustration.
