The impact of melting ice in Greenland and Antarctica on the world’s oceans is well documented. But the largest contributors to sea level rise in the 20th century were melting ice caps and glaciers located in seven other regions: Alaska, the Canadian Arctic Archipelago, the Southern Andes, High Mountain Asia, the Russian Arctic, Iceland and the Norwegian archipelago Svalbard. The five Arctic regions accounted for the greatest share of ice loss. ![]() A small glacier in the Arctic region of Norwegian archipelago Svalbard, as photographed by NASA’s Airborne Tropical Tropopause Experiment (ATTREX). This is one of the seven regions where ice loss is accelerating, causing the depletion of freshwater resources. (NASA/John Sonntag) «Read the rest of this article» Sections: Technology | No Comments
Last Photos from NASA’s Opportunity Rover on MarsNASA Jet Propulsion Laboratory
“This final panorama embodies what made our Opportunity rover such a remarkable mission of exploration and discovery,” said Opportunity project manager John Callas of NASA’s Jet Propulsion Laboratory in Pasadena, California. ![]() This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover’s Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see. (NASA/JPL-Caltech/Cornell/ASU) «Read the rest of this article» Sections: Technology | No Comments
NASA releases timeline for InSight landing on MarsNASA Jet Propulsion Laboratory
InSight’s entry, descent and landing (EDL) team, based at NASA’s Jet Propulsion Laboratory in Pasadena, California, along with another part of the team at Lockheed Martin Space in Denver, have pre-programmed the spacecraft to perform a specific sequence of activities to make this possible. ![]() This illustration shows a simulated view of NASA’s InSight lander descending on its parachute toward the surface of Mars.

NASA looks back at America’s first Satellite, Explorer 1Written by Preston Dyches
The date was January 31st, 1958. NASA had yet to be formed, and the honor of this first flight belonged to the U.S. Army. The rocket’s sole payload was a javelin-shaped satellite built by the Jet Propulsion Laboratory in Pasadena, California. Explorer 1, as it would soon come to be called, was America’s first satellite. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Radio on Europe’s Trace Gas Orbiter completes first testWritten by Guy Webster
The transmissions from NASA rovers Opportunity and Curiosity, received by one of the twin Electra radios on the orbiter on November 22nd, mark a strengthening of the international telecommunications network supporting Mars exploration. The orbiter’s main radio for communications with Earth subsequently relayed onward to Earth the data received by Electra. ![]() A NASA radio on Europe’s Trace Gas Orbiter, which reached Mars in October 2016, has succeeded in its first test of receiving data from NASA Mars rovers, both Opportunity and Curiosity. This graphic depicts the geometry of the relay from Opportunity to the orbiter, which then sent the data to Earth. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Cassini Spacecraft observes Methane Clouds moving across Saturn’s moon TitanWritten by Preston Dyches
Several sets of clouds develop, move over the surface and fade during the course of this movie sequence, which spans 11 hours, with one frame taken every 20 minutes. Most prominent are long cloud streaks that lie between 49 and 55 degrees north latitude. ![]() New video shows bright clouds of methane drifting across Saturn’s largest moon, Titan.

NASA’s Swift and NuSTAR Space Telescopes observes huge Flare erupt from Supermassive Black HoleWritten by Whitney Clavin
The two space telescopes caught a supermassive black hole in the midst of a giant eruption of X-ray light, helping astronomers address an ongoing puzzle: How do supermassive black holes flare? The results suggest that supermassive black holes send out beams of X-rays when their surrounding coronas — sources of extremely energetic particles — shoot, or launch, away from the black holes. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Curiosity Rover discovers evidence that Mars Surface Material contributes to AtmosphereWritten by Elizabeth Zubritsky
The findings come from the rover’s Sample Analysis at Mars, or SAM, instrument suite, which studied the gases xenon and krypton in Mars’ atmosphere. The two gases can be used as tracers to help scientists investigate the evolution and erosion of the Martian atmosphere. ![]() Processes in Mars’ surface material can explain why particular xenon (Xe) and krypton (Kr) isotopes are more abundant in the Martian atmosphere than expected, as measured by NASA’s Curiosity rover. Cosmic rays striking barium (Ba) or bromine (Br) atoms can alter isotopic ratios of xenon and krypton. (NASA/GSFC/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’s Juno Spacecraft prepares for Jupiter Orbit InsertionWritten by DC Agle
A minute later, Juno will cross the orbit of Jupiter’s innermost Galilean moon (Io), at 2:15pm PDT (5:15pm EDT). Juno closes the distance between it and the gas-giant world to 200,000 miles (322,000 kilometers) by 4:17pm PDT (7:17pm EDT) and is only 100,000 miles (161,000 kilometers) away by 6:03pm PDT (9:03pm EDT). ![]() NASA’s Juno spacecraft obtained this color view on June 28, 2016, at a distance of 3.9 million miles (6.2 million kilometers) from Jupiter.
