Johnson Celebrates AA and NHPI Heritage Month: Britney Tang

Johnson Celebrates AA and NHPI Heritage Month: Britney Tang

When you think about personal property, your home, clothes, and electronic devices probably come to mind. For NASA, personal property comprises government-owned government-held assets ranging from laptops to spacecraft and space station components. Managing the financial records for these assets is the responsibility of the Property Accounting Team, which includes Personal Property Accountant Britney Tang.

Tang sits within the Accounting Services Office of Johnson Space Center’s Office of the Chief Financial Services Officer (OCFO). She works with her colleagues to determine which NASA-held assets must be tracked over time versus expensed, and to ensure those assets are reported appropriately on Johnson’s financial statements.

While she has only held her civil servant position for a few months, Tang is no stranger to Johnson or the OCFO. She completed five rotations with NASA’s Pathways Program between 2021 and 2023, including two stints as a property accounting intern for her current office. “I jumped around a bit as an intern because I really wanted to have a full understanding of NASA’s whole business,” she said. “It made things click to see the entire process of how funds are being used and recorded throughout the agency.” Tang particularly enjoyed her rotations with the Property Accounting Team and feels lucky to rejoin them as a full-time employee.

As an accounting major at the University of Houston’s C.T. Bauer College of Business, Tang planned to work for a public accounting firm or a private company when she graduated, until she stumbled upon a Pathways internship opportunity. “It was in a newsletter that my school put out, which I rarely opened, but one day I did, and I saw the call for applications,” she said. “I thought I might as well throw my hat into the ring and see where it got me.”

Tang believes her experience highlights an important opportunity for NASA to attract more diverse talent by reaching out to students enrolled in a wider variety of schools and academic fields. “When you think of NASA, you think of engineers and rockets. I think that’s why a lot of people in business specifically do not consider NASA as a career option, because they forget that we do need mission support operations to keep things running,” she said. “I’m really passionate about telling people about the opportunities at NASA, especially on the business side.”

That passion prompted Tang to work with ASIA ERG to host a virtual event with the University of Houston’s Asian Business Student Association last year. At the time, she was participating in the group’s education and outreach and social cohorts as a Pathways intern. Tang developed a presentation for the event that provided overviews of Johnson’s business organizations, describing each organization’s work and related career opportunities for students. She also recruited several employees from those organizations to participate in the presentation and a brief panel discussion that followed.

Tang said that she has never felt like a minority on the teams she has been a part of, noting that her current team is almost entirely female and includes several people of color, but she knows this may not be every Johnson employee’s experience. During one intern orientation session, Tang observed that she was one of five or six women in a room of 30 people. “I did not like that feeling and I expressed that to the Pathways coordinators,” she said. “I think if people don’t see someone similar to them, or someone they can relate to, it’s harder for them to feel like they can apply.”

A self-described foodie, Tang said that showing openness and acceptance of teammates’ ethnic foods is one way that every Johnson employee can promote cultural understanding and inclusivity. Asian American families often share stories about bringing Asian food to school for lunch as kids and getting teased by other students because it smelled different, she said, adding that she hopes the growing popularity of ethnic cuisines will help put an end to those experiences. Telling her fellow Pathways interns that she enjoys trying different foods around Houston helped her build connections with them, and many approached her with questions about where they should go and what they should try. “The easiest way to start a conversation is to talk about food, and food is very integral to a culture,” she said.

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data

An analysis of data from Magellan’s radar finds two volcanoes erupted in the early 1990s. This adds to the 2023 discovery of a different active volcano in Magellan data.

Direct geological evidence of recent volcanic activity on Venus has been observed for a second time. Scientists in Italy analyzed archival data from NASA’s Magellan mission to reveal surface changes indicating the formation of new rock from lava flows linked to volcanoes that erupted while the spacecraft orbited the planet. Managed by NASA’s Jet Propulsion Laboratory in Southern California, Magellan mapped 98% of the planet’s surface from 1990 to 1992, and the images it generated remain the most detailed of Venus to date.

“Using these maps as a guide, our results show that Venus may be far more volcanically active than previously thought,” said Davide Sulcanese of d’Annunzio University in Pescara, Italy, who led the study. “By analyzing the lava flows we observed in two locations on the planet, we have discovered that the volcanic activity on Venus could be comparable to that on Earth.”

This latest discovery builds on the historic 2023 discovery of images from Magellan’s synthetic aperture radar that revealed changes to a vent associated with the volcano Maat Mons near Venus’ equator. The radar images proved to be the first direct evidence of a recent volcanic eruption on the planet. By comparing Magellan radar images over time, the authors of the 2023 study spotted changes caused by the outflow of molten rock from Venus’ subsurface filling the vent’s crater and spilling down the vent’s slopes.

Scientists study active volcanoes to understand how a planet’s interior can shape its crust, drive its evolution, and affect its habitability. The discovery of recent volcanism on Venus provides a valuable insight to the planet’s history and why it took a different evolutionary path than Earth.

Radar Backscatter

For the new study, published in the journal Nature Astronomy, the researchers likewise focused on archival data from Magellan’s synthetic aperture radar. Radio waves sent by the radar traveled through Venus’ thick cloud cover, then bounced off the planet’s surface and back to the spacecraft. Called backscatter, these reflected radar signals carried information about the rocky surface material they encountered.

The two locations studied were the volcano Sif Mons in Eistla Regio and the western part of Niobe Planitia, which is home to numerous volcanic features. By analyzing the backscatter data received from both locations in 1990 and again in 1992, the researchers found that radar signal strength increased along certain paths during the later orbits. These changes suggested the formation of new rock, most likely solidified lava from volcanic activity that occurred during that two-year period. But they also considered other possibilities, such as the presence of micro-dunes (formed from windblown sand) and atmospheric effects that could interfere with the radar signal.

To help confirm new rock, the researchers analyzed Magellan’s altimetry (surface height) data to determine slope of the topography and locate obstacles that lava would flow around.

“We interpret these signals as flows along slopes or volcanic plains that can deviate around obstacles such as shield volcanoes like a fluid,” said study co-author Marco Mastrogiuseppe of Sapienza University of Rome. “After ruling out other possibilities, we confirmed our best interpretation is that these are new lava flows.”

Using flows on Earth as a comparison, the researchers estimate new rock that was emplaced in both locations to be between 10 and 66 feet (3 and 20 meters) deep, on average. They also estimate that the Sif Mons eruption produced about 12 square miles (30 square kilometers) of rock — enough to fill at least 36,000 Olympic-size swimming pools. The Niobe Planitia eruption produced about 17 square miles (45 square kilometers) of rock, which would fill 54,000 Olympic swimming pools. As a comparison, the 2022 eruption of Mauna Loa in Hawaii, Earth’s largest active volcano, produced a lava flow with enough material to fill 100,000 Olympic pools.

“This exciting work provides another example of volcanic change on Venus from new lava flows that augments the vent change Dr. Robert Herrick and I reported last year,” said Scott Hensley, senior research scientist at JPL and co-author of the 2023 study. “This result, in tandem with the earlier discovery of present-day geologic activity, increases the excitement in the planetary science community for future missions to Venus.”

Figuring Out Volcanoes

Hensley is the project scientist for NASA’s upcoming VERITAS mission, and Mastrogiuseppe is a member of its science team. Short for Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy, VERITAS is slated to launch early next decade, using a state-of-the-art synthetic aperture radar to create 3D global maps and a near-infrared spectrometer to figure out what Venus’ surface is made of while also tracking volcanic activity. In addition, the spacecraft will measure the planet’s gravitational field to determine its internal structure.

“These new discoveries of recent volcanic activity on Venus by our international colleagues provide compelling evidence of the kinds of regions we should target with VERITAS when it arrives at Venus,” said Suzanne Smrekar, a senior scientist at JPL and principal investigator for VERITAS. “Our spacecraft will have a suite of approaches for identifying surface changes that are far more comprehensive and higher resolution than Magellan images. Evidence for activity, even in the lower-resolution Magellan data, supercharges the potential to revolutionize our understanding of this enigmatic world.”

More About the Mission

NASA’s VERITAS mission was selected in 2021 under NASA’s Discovery Program. Mission partners include Lockheed Martin Space, the Italian Space Agency, the German Aerospace Center, and Centre National d’Études Spatiales in France. The Discovery Program is managed by the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Planetary Science Division of NASA’s Science Mission Directorate in Washington.

NASA Launches Small Climate Satellite to Study Earth’s Poles

NASA Launches Small Climate Satellite to Study Earth’s Poles

Rocket Lab’s Electron rocket lifted off from Launch Complex 1 at Māhia, New Zealand at 7:41 p.m. NZST May 25, 2024 (3:41 a.m. EDT) carrying a small satellite for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission.

The first of a pair of climate satellites designed to study heat emissions at Earth’s poles for NASA is in orbit after lifting off atop Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand at 7:41 p.m. NZST (3:41 a.m. EDT) on Saturday.

The agency’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission consists of two shoebox-size cube satellites, or CubeSats, that will measure the amount of heat Earth radiates into space from two of the coldest, most remote regions on the planet. Data from the PREFIRE mission will help researchers better predict how Earth’s ice, seas, and weather will change in a warming world.

“NASA’s innovative PREFIRE mission will fill a gap in our understanding of the Earth system – providing our scientists a detailed picture of how Earth’s polar regions influence how much energy our planet absorbs and releases,” said Karen St. Germain, director of NASA’s Earth Science Division in Washington. “This will improve prediction of sea ice loss, ice sheet melt, and sea level rise, creating a better understanding of how our planet’s system will change in the coming years — crucial information to farmers tracking changes in weather and water, fishing fleets working in changing seas, and coastal communities building resilience.”

Ground controllers successfully established communications with the CubeSat at 8:48 EDT. The second PREFIRE CubeSat will set off on its own Electron rocket from Launch Complex 1 in the coming days. Following a 30-day checkout period during which engineers and scientists will make sure both CubeSats are working normally, the mission is expected to operate for 10 months.

At the heart of the PREFIRE mission is Earth’s energy budget – the balance between incoming heat energy from the Sun and the outgoing heat given off by the planet. The difference between the two is what determines the planet’s temperature and climate. A lot of the heat radiated from the Arctic and Antarctica is emitted as far-infrared radiation, but there is currently no detailed measurement of this type of energy.

The water vapor content of the atmosphere, along with the presence, structure, and composition of clouds, influences the amount of far-infrared radiation that escapes into space from Earth’s poles. Data collected from PREFIRE will give researchers information on where and when far-infrared energy radiates from the Arctic and Antarctic environments into space.

“The PREFIRE CubeSats may be small, but they’re going to close a big gap in our knowledge about Earth’s energy budget,” said Laurie Leshin, director, NASA’s Jet Propulsion Laboratory in Southern California. “Their observations will help us understand the fundamentals of Earth’s heat balance, allowing us to better predict how our ice, seas, and weather will change in the face of global warming.”

The mission’s CubeSats each carry an instrument called a thermal infrared spectrometer, which use specially shaped mirrors and sensors to measure infrared wavelengths. Miniaturizing the instruments to fit on CubeSats necessitated downsizing some parts while scaling up other components.

“Our planet is changing quickly, and in places like the Arctic, in ways that people have never experienced before,” said Tristan L’Ecuyer, PREFIRE’s principal investigator, University of Wisconsin, Madison. “NASA’s PREFIRE will give us new measurements of the far-infrared wavelengths being emitted from Earth’s poles, which we can use to improve climate and weather models and help people around the world deal with the consequences of climate change.”

NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, in partnership with NASA’s Earth System Science Pathfinder Program is providing the launch service as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.

The PREFIRE mission was jointly developed by NASA and the University of Wisconsin-Madison. NASA JPL manages the mission for the agency’s Science Mission Directorate and provided the spectrometers. Blue Canyon Technologies built the CubeSats and the University of Wisconsin-Madison will process the data the instruments collect. The launch services provider is Rocket Lab USA Inc. of Long Beach, California.
