NASA set a new distance record for CubeSats on May 8th when a pair of CubeSats called Mars Cube One (MarCO) reached 621,371 miles (1 million kilometers) from Earth. One of the CubeSats, called MarCO-B (and affectionately known as “Wall-E” to the MarCO team) used a fisheye camera to snap its first photo on May 9th. That photo is part of the process used by the engineering team to confirm the spacecraft’s high-gain antenna has properly unfolded. ![]() The first image captured by one of NASA’s Mars Cube One (MarCO) CubeSats. The image, which shows both the CubeSat’s unfolded high-gain antenna at right and the Earth and its moon in the center, was acquired by MarCO-B on May 9.

NASA’s Juno Spacecraft to make Seventh Pass over JupiterWritten by DC Agle
At the time of perijove (defined as the point in Juno’s orbit when it is closest to the planet’s center), the spacecraft will be about 2,200 miles (3,500 kilometers) above the planet’s cloud tops. Juno launched on August 5th, 2011, from Cape Canaveral, Florida, and arrived in orbit around Jupiter on July 4th, 2016. During its mission of exploration, Juno soars low over the planet’s cloud tops — as close as about 2,100 miles (3,400 kilometers). ![]() Citizen scientist David Englund created this avant-garde Jovian artwork using data from the JunoCam imager on NASA’s Juno spacecraft.

NASA Scientists examine Methane Hot Spots in Four Corners area of United StatesWritten by Alan Buis
Scientists from NASA’s Jet Propulsion Laboratory and Caltech, both in Pasadena, California; the National Oceanic and Atmospheric Administration (NOAA), Boulder, Colorado; and the University of Michigan, Ann Arbor, used two JPL airborne spectrometers to identify and measure more than 250 individual sources of methane. ![]() The Four Corners region of New Mexico and Colorado. Numerous light-colored spots are sites of gas and oil development. (Flickr user Doc Searls, CC-BY-SA 2.0) «Read the rest of this article» Sections: Technology | No Comments
NASA scientists study changes to Earth’s Ozone levelsWritten by Alan Buis
The finding is good news, since human and plant health are harmed by exposure to ozone near the ground. Significant increases in ozone in Earth’s lowest atmospheric layer, the troposphere, would also lead to additional climate warming because ozone is a greenhouse gas. ![]() Astronauts aboard the International Space Station captured this photograph of Earth’s atmospheric layers on July 31, 2011, revealing the troposphere (orange-red) to the stratosphere and above. Earth-observing instruments in space allow scientists to better understand the chemistry and dynamics occurring within and between these layers.
