Sentinel-6 returning most precise data ever on sea level


Recommended Posts

Copernicus Sentinel-2 takes us over the Tarawa Atoll in the Republic of Kiribati – a remote Pacific nation threatened by rising seas.

Sea-level rise is one of the most immediate consequences of climate change, as highlighted recently through urgent pleas from leaders of island nations at the COP26 summit. Global measures of sea-level rise are imperative to underpinning global policy and for strategies to protect coastlines and low-lying lands. Measuring tiny differences in the height of the sea surface from space is no easy task – but that’s exactly what the Copernicus Sentinel-6 Michael Freilich satellite is doing. And, after a year of exhaustive testing, this new mission is now delivering the world’s most accurate data on sea-level rise.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NAS visualization & data sciences lead Chris Henze demonstrates the newly upgraded hyperwall visualization system to Ames center director Eugene Tu, deputy center director David Korsmeyer, and High-End Computing Capability manager William Thigpen.NASA/Brandon Torres Navarette In May, the NASA Advanced Supercomputing (NAS) facility, located at NASA’s Ames Research Center in California’s Silicon Valley, celebrated the newest generation of its hyperwall system, a wall of LCD screens that display supercomputer-scale visualizations of the very large datasets produced by NASA supercomputers and instruments. 
      The upgrade is the fourth generation of hyperwall clusters at NAS. The LCD panels provide four times the resolution of the previous system, now spanning across a 300-square foot display with over a billion pixels. The hyperwall is one of the largest and most powerful visualization systems in the world. 
      Systems like the NAS hyperwall can help researchers visualize their data at large scale, across different viewpoints or using different parameters for new ways of analysis. The improved resolution of the new system will help researchers “zoom in” with greater detail. 
      The hyperwall is just one way researchers can utilize NASA’s high-end computing technology to better understand their data. The NAS facility offers world-class supercomputing resources and services customized to meet the needs of about 1,500 users from NASA centers, academia and industry.

      Jake Cupani, a data science specialist, focuses on the intersection between data visualization and user experience — UX — design.
      Name: Jake Cupani
      Title: Financial analytics support specialist
      Organization: Financial Analytics and Systems Office, Office of the Chief Financial Officer (Code 156)
      Jake Cupani is a financial analytics support specialist at Goddard Space Flight Center in Greenbelt, Md. Photo courtesy of Jake Cupani What do you do and what is most interesting about your role here at Goddard?
      I create data visualizations and dashboards to help visualize some of the key metrics including demographics, budgeting, and forecasting. I enjoy helping our office modernize and automate their processes.
      What is your educational background?
      In 2020, I got a B.S. in information science with a minor in astronomy from the University of Maryland. In 2022, I got a master’s in information management and data analytics also from the University of Maryland.
      How did you come to Goddard?
      After graduating, I did some consulting. I came to Goddard in 2023, but I had interned for Goddard throughout my academic career. My office knew about my work and recruited me.
      You describe yourself as a data science specialist. What do you mean?
      Data science encompasses everything from data visualization to analysis and specifics as well as data preparation. Data visualization focuses on taking any sort of data, be it spreadsheets or tables, and creating graphs and interactive charts to explain the data and gather insights on the data.
      What is most important to you as a data science specialist?
      What I think is important is the intersection between the visualization and the user experience. You have to make it easy for people to digest the analytics so that they can understand the ideas you are trying to get across and the overall trends.
      As a person fairly new to Goddard, what are your initial impressions?
      What is great about Goddard is that everyone seems really open to helping. Everyone works collaboratively. You can always ask questions. Goddard has a collegial environment.
      It is very refreshing to be in an environment that is so open and welcoming. People from all different walks of life work at Goddard and this diversity enables us to accomplish all the things that we do. People are willing to listen to other people’s ideas.
      Who is your mentor and what have you learned?
      My mentor is my boss, John Brady. I thank him for being such a good leader and listener. He taught me about Goddard’s culture and how decisions are made.
      What is your involvement with the LGBTQ+ Employee Resource Group?
      Although not in a leadership role, I attend the monthly meetings where we get together and have lunch. Sometimes we have speakers, other times we just talk. These lunches help me engage with the LGBTQ+ community.

      I would tell them that working at Goddard is an amazing opportunity that will allow them to meet a lot of really smart people who also very welcoming. I would tell them not to be shy and to talk to as many people as they can.
      Where do you see yourself in five years?
      In five years, I want to still work in data visualization and continue to learn as much as I can to grow my expertise. Beyond that, I don’t know what is in the future for me.
      What do you do for fun?
      I like baking cookies, brownies, and cakes. I am also a big fan of playing video games, especially Pokémon.

      Voyager 1 Returning Science Data From All Four Instruments
      An artist’s concept of the Voyager spacecraft. NASA/JPL-Caltech The spacecraft has resumed gathering information about interstellar space.
      NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
      The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.  
      The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.
      While Voyager 1 is back to conducting science, additional minor work is needed to clean up the effects of the issue. Among other tasks, engineers will resynchronize timekeeping software in the spacecraft’s three onboard computers so they can execute commands at the right time. The team will also perform maintenance on the digital tape recorder, which records some data for the plasma wave instrument that is sent to Earth twice per year. (Most of the Voyagers’ science data is sent directly to Earth and not recorded.)
      Voyager 1 is more than 15 billion miles (24 billion kilometers) from Earth, and Voyager 2 is more than 12 billion miles (20 billion kilometers) from the planet. The probes will mark 47 years of operations later this year. They are NASA’s longest-running and most-distant spacecraft. Both spacecraft flew past Jupiter and Saturn, while Voyager 2 also flew past Uranus and Neptune.

      NASA/Wanmei Liang, using MODIS data from NASA EOSDIS LANCE and GIBS/Worldview NASA’s Terra satellite captured floating fragments of sea ice as ocean currents carried them south along Greenland’s east coast on June 4, 2024.
      This ice traveled from the Fram Strait, a 450-kilometer (280-mile)-wide passage between Greenland and Svalbard, to the Arctic Ocean. Along the journey, it breaks into smaller pieces and starts to melt in warmer ocean waters, creating the wispy patterns seen here.
