'S.S. J.R. Thompson' Departs International Space Station and Successfully Completes ISS Reboost

From May 24, 2018 when the CRS-9 “S.S. J.R. Thompson” Cygnus arrived at the International Space Station and delivered approximately 7,400 pounds of cargo to astronauts on board. The spacecraft successfully departed from the station on July 15. Credit: Northrop Grumman Corporation

Northrop Grumman Corporation announced that its Cygnus spacecraft, following a highly successful stay at the International Space Station, has departed from the station to begin the next phase of its mission.

Juno Data Indicate Another Possible Volcano on Jupiter Moon Io

This annotated image highlights the location of the new heat source in the southern hemisphere of the Jupiter moon Io. The image was generated from data collected on Dec. 16, 2017, by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA's Juno mission when the spacecraft was about 290,000 miles (470,000 kilometers) from the Jovian moon. In this infrared image, the brighter the color the higher the temperature recorded by JIRAM. Credits: NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM

Data collected by NASA’s Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano on the small moon of Jupiter. The infrared data were collected on Dec. 16, 2017, when Juno was about 290,000 miles (470,000 kilometers) away from the moon.

SKA Precursor Telescope MeerKAT Inaugurated In South Africa

South Africa’s 64-dish MeerKAT telescope, one of the SKA’s precursor telescopes, was officially inaugurated by Deputy President David Mabuza at a ceremony near Carnarvon on Friday, July 13.

GAO Report on Commercial Crew Suggests: ‘The Hell They Will Launch (Operational Crew) Before 2019’

Predictions by SpaceX’s president, Gwynn Shotwell, that the company’s Crew Dragon spacecraft would fly with astronauts by 2018 appear to be inaccurate. Similarly Boeing’s entry in NASA’s Commercial Crew Program are not expected to able to achieve key certification objectives this year either, according to a government report.

In Search of Dark Matter

Scientists Trace a Single Neutrino Back to a Galaxy Billions of Light Years Away

A neutrino, having interacted with a molecule of ice, produces a secondary particle -- a muon --that moves at relativistic speed in the ice, leaving a trace of blue light behind it.  Credit: Nicolle R. Fuller/NSF/IceCube

An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth.
