Exactly 20 years ago today, NASA’s TIMED mission launched from the California coast on a journey to unveil new secrets about the upper climes of Earth’s atmosphere. Developed in part by Johns Hopkins APL, the mission’s unrivaled 20-year dataset has provided crucial insights about space weather, Earth’s climate and the evolution of planetary atmospheres.
A new study suggests hunting for nontraditional signatures of potentially habitable worlds, which would be easier to detect with current resources in less time. These so-called atmospheric beacons of life - hydroxyl, molecular oxygen, and nitric oxide - are produced from reactive nitrogen and oxygen atoms through a cascade of chemical reactions. Data from NASA's Earth-studying TIMED mission was used to simulate how infrared observations of these beacons might appear. (November 2, 2017)
NASA's TIMED mission - short for Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics - yielded a batch of new discoveries to end its 15th year in orbit. From a more precise categorization of the upper atmosphere's response to solar storms, to pinpointing the signatures of a fundamental behavior of carbon dioxide, TIMED's unique position and instruments, along with its decade-plus data record, continue to give scientists an unparalleled look at Earth's upper atmosphere, our interface to space. Indeed, the very length of the data set has provided unprecedented opportunities to analyze near-Earth space. (January 4, 2017)
The NASA TIMED spacecraft, which studies the impact of solar- and human-induced disturbances on Earth's upper atmosphere, celebrated 5,000 days of continuous data collection on Aug. 15, 2015. During that time, the spacecraft completed more than 74,000 Earth orbits and accumulated more than 9 terabytes of data, served by the TIMED Mission Science Data Center located at the Johns Hopkins University Applied Physics Laboratory (APL) and now archived at the Space Physics Data Facility at the NASA Goddard Space Flight Center.

'Space bubbles' may have led to deadly battle in Afghanistan
On 4 March 2002, U.S. Army Rangers flew by helicopter on a rescue mission of a Navy SEALS team shot down by al-Qaida forces on the Afghan mountain Takur Ghar. While in flight, radio messages failed to reach them warning that their landing zone was learned to be held by al-Qaida forces. The ensuing 17-hour firefight cost seven lives. Subsequent research, based upon GUVI data, suggests that turbulent pockets of ionized gas may have caused a temporary communications blackouts in the region.
