Preparations for Next Moonwalk Simulations Underway (and Underwater)

This summer between June 17 and July 2, NASA will fly aircraft over Baltimore, Philadelphia, parts of Virginia, and California to collect data on air pollutants and greenhouse gas emissions.  

The campaign supports the NASA Student Airborne Research Program for undergraduate interns.

The East Coast flights will take place from June 17-26. Researchers and students will fly multiple times each week in Dynamic Aviation’s King Air B200 aircraft at an altitude of 1,000 feet over Baltimore and Philadelphia as well as Norfolk, Hampton, Hopewell, and Richmond in Virginia. Meanwhile, a NASA P-3 aircraft based out of NASA’s Wallops Flight Facility in Virginia will fly over the same East Coast locations to collect different measurements.

The West Coast flights will occur from June 29 – July 2. During the period, those same aircraft will conduct similar operations over Los Angeles, Imperial Valley, and Tulare Basin in California.

The research aircraft will fly at lower altitudes than most commercial planes and will conduct maneuvers including vertical spirals from 1,000 to 10,000 feet, circling over power plants, landfills, and urban areas. They will also occasionally conduct “missed approaches” at local airports, where the aircraft will perform a low-level flyby over a runway to collect samples close to the surface.

The aircraft carry instruments that will collect data on a range of greenhouse gases including carbon dioxide and methane, as well as air pollutants such as nitrogen dioxide, formaldehyde, and ozone. One purpose of this campaign is to validate space-based measurements observed by the TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission. Launched on a commercial satellite in April 2023, the TEMPO instrument provides hourly daytime measurements of air pollutants across the United States, northern Mexico, and southern Canada.

“The goal is that this data we collect will feed into policy decisions that affect air quality and climate in the region,” said Glenn Wolfe, a research scientist and the principal investigator for the campaign at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The B-200 aircraft is owned by Dynamics Aviation, an aircraft company contracted by NASA.

      The latest crew chosen by NASA to venture on a simulated trip to Mars inside the agency’s Human Exploration Research Analog. From left are Sergii Iakymov, Erin Anderson, Brandon Kent, and Sarah Elizabeth McCandless.Credit: C7M3 Crew NASA selected a new team of four research volunteers to participate in a simulated mission to Mars within HERA (Human Exploration Research Analog) at the agency’s Johnson Space Center in Houston.
      Erin Anderson, Sergii Iakymov, Brandon Kent, and Sarah Elizabeth McCandless will begin their simulated trek to Mars on Friday, Aug. 9. The volunteer crew members will stay inside the 650-square-foot habitat for 45 days, exiting Monday, Sept. 23 after a simulated “return” to Earth. Jason Staggs and Anderson Wilder will serve as alternate crew members.
      The HERA missions offer scientific insights into how people react to the type of isolation, confinement, work and life demands, and remote conditions astronauts might experience during deep space missions.
      The facility supports more frequent, shorter-duration simulations in the same building as CHAPEA (Crew Health and Performance Analog). This crew is the third group of volunteers to participate in a simulated Mars mission in HERA this year. The most recent crew completed its HERA mission on June 24. In total, there will be four analog missions in this series.
      During this summer’s simulation, participants will perform a mix of science and operational tasks, including harvesting plants from a hydroponic garden, growing shrimp, deploying a small, cube-shaped satellite (CubeSat) to simulate gathering virtual data for analysis, “walking” on the surface of Mars using virtual reality goggles, and flying simulated drones on the simulated Mars surface. The team members also will encounter increasingly longer communication delays with Mission Control throughout their mission, culminating in five-minute lags as they “near” Mars. Astronauts traveling to Mars may experience communications delays of up to 20 minutes.
      NASA’s Human Research Program will conduct 18 human health experiments during each of the 2024 HERA missions. Collectively, the studies explore how a Mars-like journey may affect the crew members’ mental and physical health. The work also will allow scientists to test certain procedures and equipment designed to keep astronauts safe and healthy on deep space missions.

      Image data: NASA/JPL-Caltech/SwRI/MSSS
      Image processing by Gary Eason © CC BY During its 61st close flyby of Jupiter on May 12, 2024, NASA’s Juno spacecraft captured this color-enhanced view of the giant planet’s northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter’s clouds break down, leading to turbulent patterns and cloud structures that rapidly evolve over the course of only a few days.
      Citizen scientist Gary Eason made this image using raw data from the JunoCam instrument, applying digital processing techniques to enhance color and clarity.
      At the time the raw image was taken, the Juno spacecraft was about 18,000 miles (29,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 68 degrees north of the equator.
      JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing.
