Goddard Monitors Smoke from Canada Wildfires
2023.06.07
An unusually intense start to Canada’s wildfire season filled skies with smoke in May 2023. Then, at the beginning of June, scores of new fires raged in the eastern Canadian province of Quebec. NASA’s Aqua satellite, operated at Goddard, has captured imagery of the smoke. The Global Modeling and Assimilation Office (GMAO) based at Goddard has computed models of where the smoke may travel in coming days.

Geodesy Technology Innovation
2022.08.25
The Summer 2022 issue of CuttingEdge (A NASA GSFC periodical dedicated to emerging technologies) features work by Scott Luthcke (61A) and partners on the gravity-measuring Atom Interferometer Gravity Gradiometer (AIGG) in an article entitled "Satellite Geodesy – Innovation Born at Goddard" (pp. 7–9).
The Atom Interferometer Gravity Gradiometer, developed in partnership with the Fremont, California-based AOSense, offers the potential for accurate, direct, real-time measurement of Earth’s gravitational field and its changes over time. Scott Luthcke and Goddard physicist Babak Saif (Code 551) led development of the gravity-measuring technology, which works by pulsing a laser through a cloud of super-cooled atoms. Measuring the laser’s interaction with the atoms creates an interference pattern. Scientists know how the atoms should be-have at a quantum level, so the interference serves as a real-time measurement of gravity’s pull on the atoms.
Shortest Day Gets Attention
2022.08.23
Stephen Merkowitz (61A) was recently interviewed by media outlets such as the Associated Press, The World on Public Radio, and Verify for articles about the recent shortest length of day on record.

NASA GLOBE Land Cover Challenge 2022: Land Cover in a Changing Climate
2022.07.26
The Global Learning and Observations to Benefit the Environment (GLOBE) Program invites you to take part in our upcoming Land Cover Challenge: “Land Cover in a Changing Climate.”
The photos you take using The GLOBE Program’s GLOBE Observer app document the current land cover and may also show evidence of land cover or land use change in the area. We especially encourage you to look for places you know have changed (or where you know change is coming), and put any information about the reasons or timing for that change in the field notes section. While existing land cover databases (such as the 50-year record from the Landsat satellite) may be able to indicate where change is happening, they don’t always include the reasons why those changes occurred, so any local, on-the-ground knowledge you share with us can be especially helpful.

New NASA VGOS Antenna Installed and Passes Site Acceptance Test at McDonald Observatory
2019.03.06
The NASA Space Geodesy Project (SGP) has taken the next step in expanding the NASA Space Geodesy Network (NSGN) with the procurement of a VLBI Global Observing System (VGOS) 12-m radio telescope for a new core site located at the McDonald Observatory, near Fort Davis, Texas. Intertronic Solutions Inc. completed the installation of the antenna early in February 2019. An engineering room-temperature feed, developed and installed by MIT/Haystack Observatory, was used to support the pointing tests. On February 15, 2019 several extragalactic sources were observed. The antenna successfully passed the Site Acceptance Test (SAT) on February 20, 2019. A cryogenic, broad-band signal chain will be installed in April 2019. Afterwards the station will begin commissioning activities, and later in the year will being participating in VGOS test sessions, organized in coordination with the International VLBI Service for Geodesy and Astrometry (IVS).
