NASA’s Mars InSight lander has measured and recorded for the first time ever a likely “marsquake.”
The faint seismic signal, detected by the lander’s Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander’s 128th Martian day, or sol. This is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.
NASA will pay tribute to the crews of Apollo 1 and space shuttles Challenger and Columbia, as well as other NASA colleagues, during the agency’s Day of Remembrance on Thursday, Jan. 28, the 30th anniversary of the Challenger accident. NASA’s Day of Remembrance honors members of the NASA family who lost their lives while furthering the cause of exploration and discovery.
NASA Administrator Charles Bolden, Deputy Administrator Dava Newman, and other agency senior officials will hold an observance and wreath-laying at Arlington National Cemetery in Virginia starting at 9 a.m. EST. Following the wreath-laying ceremony at Arlington, various NASA centers will hold remembrance events Thursday for employees and the families of those lost in service to America’s space program.
At 10 a.m., NASA Television will provide live coverage of a wreath-laying ceremony at the Space Mirror Memorial located at the Kennedy Space Center Visitor Complex in Florida. The observance is hosted by the Astronauts Memorial Foundation, which is a private, not-for-profit organization. It built and maintains the Space Mirror Memorial, which was dedicated in 1991 to honor all astronauts who lost their lives on missions or during training. It has been designated a National Memorial by Congress.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, will observe the day with a candle-lighting ceremony for center employees, as well as a public event at the U.S. Space & Rocket Center, Marshall’s official visitor center, at 10 a.m. CST. NASA’s Johnson Space Center in Houston, will hold an event for employees that includes placing flowers at the Apollo, Challenger and Columbia Trees at the center.
In partnership with the Challenger Learning Center of Northwest Indiana, NASA’s Glenn Research Center will host former astronaut Greg Harbaugh for the opening of the exhibit “Inspiring the Future — The Legacy of Exploration,” at the Indiana Welcome Center in Hammond.
