Topic: NASA’s Goddard Space Flight CenterWritten by Lori Keesey
Mahmooda Sultana won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and then transmitting that data via a wireless antenna — all from the same self-contained platform that measures just two-by-three-inches in size. Under a $2 million technology development award, Sultana and her team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will spend the next two years advancing the autonomous multifunctional sensor platform. ![]() Technologist Mahmooda Sultana holds an early iteration of an autonomous multifunctional sensor platform, which could benefit all of NASA’s major scientific disciplines and efforts to send humans to the Moon and Mars.

NASA’s SPHEREx mission to look into History of the UniverseNASA Headquarters
The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is a planned two-year mission funded at $242 million (not including launch costs) and targeted to launch in 2023. ![]() NASA’s Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is targeted to launch in 2023. SPHEREx will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy’s planetary systems.

NASA Finds Possible Second Impact Crater Under Greenland IceWritten By Maria-José Viñas
If the second crater, which has a width of over 22 miles, is ultimately confirmed as the result of a meteorite impact, it will be the 22nd largest impact crater found on Earth. ![]() Just 114 miles from the newly-found Hiawatha impact crater under the ice of northwest Greenland, lies a possible second impact crater. The 22-mile wide feature would be the second crater found under an ice sheet, and if confirmed, would be the 22nd-largest crater on Earth.

NASA’s MAVEN Spacecraft to reduce Orbit around MarsNASA’s Goddard Space Flight Center
The operation will reduce the highest point of the MAVEN spacecraft’s elliptical orbit from 3,850 to 2,800 miles (6,200 to 4,500 kilometers) above the surface and prepare it to take on additional responsibility as a data-relay satellite for NASA’s Mars 2020 rover, which launches next year. “The MAVEN spacecraft has done a phenomenal job teaching us how Mars lost its atmosphere and providing other important scientific insights on the evolution of the Martian climate,” said Jim Watzin, director of NASA’s Mars Exploration Program. “Now we’re recruiting it to help NASA communicate with our forthcoming Mars rover and its successors.” ![]() Aerobraking plan for MAVEN. (left) Current MAVEN orbit around Mars: 6,200 kilometers (~3,850 miles) at highest altitude, and an orbit period of about 4.5 hours. (center) Aerobraking process: MAVEN performs a series of “deep dip” orbits approaching to within about 125 kilometers (~78 miles) of Mars at lowest altitude, causing drag from the atmosphere to slow down the spacecraft.

NASA, NOAA say 2018 Fourth Warmest Year since 1880NASA Headquarters
Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. Globally, 2018’s temperatures rank behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record. ![]() This line plot shows yearly temperature anomalies from 1880 to 2018, with respect to the 1951-1980 mean, as recorded by NASA, NOAA, the Japan Meteorological Agency, the Berkeley Earth research group, and the Met Office Hadley Centre (UK).

NASA’s NICER instrument discovers Black Hole consuming nearby StarWritten by Jeanette Kazmierczak
NICER detected X-ray light from the recently discovered black hole, called MAXI J1820+070 (J1820 for short), as it consumed material from a companion star. Waves of X-rays formed “light echoes” that reflected off the swirling gas near the black hole and revealed changes in the environment’s size and shape. ![]() In this illustration of a newly discovered black hole named MAXI J1820+070, a black hole pulls material off a neighboring star and into an accretion disk. Above the disk is a region of subatomic particles called the corona. (Aurore Simonnet and NASA’s Goddard Space Flight Center) «Read the rest of this article» Sections: Technology | No Comments
NASA Telescopes used to study unusual Flash of Light nicknamed “The Cow”Written by Jeanette Kazmierczak
Over three days, the Cow produced a sudden explosion of light at least 10 times brighter than a typical supernova, and then it faded over the next few months. ![]() AT2018cow erupted in or near a galaxy known as CGCG 137-068, which is located about 200 million light-years away in the constellation Hercules. This zoomed-in image shows the location of the “Cow” in the galaxy. (Sloan Digital Sky Survey) «Read the rest of this article» Sections: Technology | No Comments
Citizen Scientists use NASA’s Kepler Space Telescope data to discover New WorldWritten by Francis Reddy
“It’s a very exciting discovery due to how it was found, its temperate orbit and because planets of this size seem to be relatively uncommon,” said Adina Feinstein, a University of Chicago graduate student who discussed the discovery on Monday, January 7th, at the 233rd meeting of the American Astronomical Society in Seattle. ![]() The newfound planet K2-288Bb, illustrated here, is slightly smaller than Neptune. Located about 226 light-years away, it orbits the fainter member of a pair of cool M-type stars every 31.3 days.

NASA Sounding Rocket Probes the Dark Regions of SpaceWritten by Mara Johnson-Groh
The rocket carried the payload to 175 miles altitude before descending and landing by parachute. Payload recovery is in progress. The experiment team reports that great data was received during the flight. ![]() The DEUCE payload sits atop a NASA Black Brant IX sounding rocket at the White Sands Missile Range in New Mexico.

NASA Lucy Spacecraft to navigate to Jupiter’s Trojan AsteroidsWritten by Tamsyn Brann
In 2021, the feat of navigation that is the Lucy mission will launch. To steer Lucy towards its targets doesn’t simply involve programming a map into a spacecraft and giving it gas money – it will fly by six asteroid targets, each in different orbits, over the course of 12 years. ![]() This diagram illustrates Lucy’s orbital path. The spacecraft’s path (green) is shown in a frame of reference where Jupiter remains stationary, giving the trajectory its pretzel-like shape. After launch in October 2021, Lucy has two close Earth flybys before encountering its Trojan targets. In the L4 cloud Lucy will fly by (3548) Eurybates (white), (15094) Polymele (pink), (11351) Leucus (red), and (21900) Orus (red) from 2027-2028. After diving past Earth again Lucy will visit the L5 cloud and encounter the (617) Patroclus-Menoetius binary (pink) in 2033.
