El viceministro de Políticas para la Defensa del Ministerio de Defensa de Perú, César Medardo Torres Vega, el administrador de la NASA, Bill Nelson, y el director de la Comisión Nacional de Investigación y Desarrollo Aeroespacial del Perú (CONIDA), mayor general Roberto Melgar Sheen, se reúnen en Lima, Perú, el 14 de noviembre de 2024, donde EE. UU. y Perú firmaron un memorando de entendimiento acordando estudiar una potencial campaña de cohetes sonda.Crédito: Embajada de EE. UU. en Perú Read this release in English here.
La NASA y la Comisión Nacional de Investigación y Desarrollo Aeroespacial del Perú (CONIDA) sentaron las bases para una posible campaña de varios años de duración para el lanzamiento de pequeños cohetes científicos desde Perú, conjuntamente con Estados Unidos.
Ambos países firmaron el jueves un memorando de entendimiento no vinculante que incluye capacitación en seguridad, un estudio de factibilidad conjunto para la posible campaña, y asistencia técnica para CONIDA en lanzamientos de cohetes sonda. Los cohetes sonda son pequeños cohetes de bajo costo que proporcionan acceso suborbital al espacio.
“Estamos entusiasmados de analizar la posibilidad de lanzar nuevamente cohetes sonda desde Perú”, dijo el administrador de la NASA, Bill Nelson, quien firmó en nombre de Estados Unidos. “Este acuerdo profundiza nuestra colaboración internacional con Perú y la investigación científica que llevamos a cabo debido a la ubicación del país en el ecuador magnético. Juntos iremos más lejos”.
El mayor general Roberto Melgar Sheen, jefe institucional de CONIDA, firmó en nombre de Perú. Brian Nichols, subsecretario de Asuntos del Hemisferio Occidental del Departamento de Estado de EE. UU., y Stephanie Syptak-Ramnath, embajadora de EE. UU. en Perú, también participaron, entre otros funcionarios peruanos. El evento tuvo lugar durante la semana del Foro de Cooperación Económica Asia-Pacífico que comenzó el 9 de noviembre en Lima.
Durante su visita a Perú, Nelson también discutió la importancia de las asociaciones y la colaboración internacionales en el espacio y celebró la firma de los Acuerdos Artemis por parte de Perú a principios de este año.
Estados Unidos y Perú tienen una larga historia de cooperación espacial. La NASA llevó a cabo campañas de cohetes sonda en la base de lanzamiento Punta Lobos de CONIDA en 1975 y 1983.
La NASA utiliza cohetes sonda para transportar instrumentos científicos al espacio en vuelos suborbitales para recopilar importantes datos científicos y poner a prueba prototipos de instrumentos. Con ellos se obtienen datos de incalculable valor que mejoran nuestra comprensión de la atmósfera y el clima de la Tierra, nuestro sistema solar y el universo, y se ponen a prueba equipamientos para viajes espaciales más profundos.
Comprender la atmósfera de la Tierra y cómo es influenciada por el Sol es crucial para proteger los recursos terrestres y espaciales de los que dependemos todos los días, desde la red eléctrica hasta los datos meteorológicos e incluso la navegación.

Credit: NASA NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Southwest Research Institute of San Antonio to build three coronagraphs for the Lagrange 1 Series project, part of NOAA’s Space Weather Next program.
Once operational, the coronagraphs will provide critical data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings, and alerts that help mitigate space weather impacts, including electric power outages and interruption to communications and navigation systems.
This cost-plus-fixed-fee contract is valued at approximately $60 million, and the anticipated period of performance is from this November through January 2034, concluding after launch of the second coronagraph aboard a NOAA spacecraft. The third coronagraph will be delivered as a flight spare.
This contract award marks a transfer of coronagraph development from the government to the U.S. commercial sector. The contract scope includes design, analysis, development, fabrication, integration, test, verification, and evaluation of the coronagraphs; launch support; supply and maintenance of ground support equipment; and support of post-launch instrument operations at the NOAA Satellite Operations Facility. The work will take place at Southwest Research Institute’s facility in San Antonio.
The coronagraphs will observe the density structure of the Sun’s faint outermost atmosphere — the corona — and will detect Earth-directed coronal mass ejections shortly after they erupt, providing the longest possible lead time for geomagnetic storm watches. With this forewarning, public and private organizations affected by space weather can take actions to protect their assets. The coronagraphs will also provide data continuity from the Space Weather follow-on Lagrange 1 mission.
NASA and NOAA oversee the development, launch, testing and operation of all the satellites in the project. NOAA is the program owner providing the requirements and funding along with managing the program, operations, data products, and dissemination to users. NASA and its commercial partners develop and build the instruments, spacecraft, and provide launch services on behalf of NOAA.

Johnson Space Center Vibration Test FacilityNASA Nov. 14, 2024
NASA Johnson Invites Proposals to Lease Vibration Test Facility
NASA’s Johnson Space Center is seeking proposals for the use of its historic, but underused, Vibration and Acoustic Test Facility. Prospective tenants must submit facility walk-through requests by Monday, Nov. 18.
Final proposals are due by 12 p.m. EST Monday, Dec. 16, and must promote activities that will build, expand, modernize, or operate aerospace-related capabilities at NASA Johnson and help preserve the historic and iconic building through preservation and adaptive reuse.
NASA plans to sign a National Historic Preservation Act (NHPA) lease agreement for the facility, also known as Building 49, for a five-year base period and one five-year extension to be negotiated between NASA and the tenant. To request a walk-through, send an email to hq-realestate@mail.nasa.gov.
“This historic facility has been used for decades to ensure the success and safety of all human spaceflight missions by putting engineering designs and hardware to the ultimate stress tests,” said NASA Johnson Director Vanessa Wyche. “For more than 60 years, NASA Johnson has been the hub of human space exploration and this agreement will be a vital part of the center’s efforts to develop a robust and durable space economy that refines our understanding of the solar system and space exploration.”
All proposals must adhere to the guidelines detailed in the Agency Announcement for Proposals describing concept plans for development of the property, including any modifications proposed to the building; a statement of financial capability to successfully achieve and sustain operations, demonstrated experience with aerospace-related services or other space-related activities, and a detailed approach to propelling the space economy.
The nine-story building complex has a gross square footage of 62,737 square feet and consists of a north wing measuring 62 feet long, 268 feet wide and 106 feet tall, and a central wing about 64 feet long and 115 feet wide. Building 49 currently houses five laboratories, including the General Vibration Laboratory, Modal Operations Laboratory, Sonic Fatigue Laboratory, Spacecraft Acoustic Laboratory, and Spacecraft Vibration Laboratory. The south administrative portion of the building is not included in the property offered for lease.
As the home of Mission Control Center for the agency’s human space missions, astronaut training, robotics, human health and space medicine, NASA Johnson leads the way for the human exploration. Leveraging its unique role and location, the center is developing multiple lease agreements, including the recently announced Exploration Park, to sustain its key role in helping the human spaceflight community foster a robust space.
In the coming years, NASA and its academic, commercial, and international partners will see the completion of the International Space Station Program, the commercial development of low Earth orbit, and the first human Artemis campaign missions establishing sustainable human presence on the Moon in preparation for human missions to Mars.
Johnson already is leading the commercialization of space with the commercial cargo and crew programs and private astronaut missions to the space station. The center also is supporting the development of commercial space stations in low Earth orbit, and lunar-capable commercial spacesuits and lunar landers that will be provided as services to both NASA and the private sector to accelerate human access to space. Through the development of Exploration Park, the center will broaden the scope of the human spaceflight community that is tackling the many difficult challenges ahead.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s EMIT collected this hyperspectral image of the Amazon River in northern Brazil on June 30 as part of an effort to map global ecosystem biodiversity. The instrument was originally tasked with mapping minerals over deserts; its data is now being used in research on a diverse range of topics. NASA/JPL-Caltech The imaging spectrometer measures the colors of light reflected from Earth’s surface to study fields such as agriculture, hydrology, and climate science.
Observing our planet from the International Space Station since July 2022, NASA’s EMIT (Earth Surface Mineral Dust Source Investigation) mission is beginning its next act.
At first the imaging spectrometer was solely aimed at mapping minerals over Earth’s desert regions to help determine the cooling and heating effects that dust can have on regional and global climate. The instrument soon added another skill: pinpointing greenhouse gas emission sources, including landfills and fossil fuel infrastructure.
Following a mission extension this year, EMIT is now collecting data from regions beyond deserts, addressing topics as varied as agriculture, hydrology, and climate science.
Imaging spectrometers like EMIT detect the light reflected from Earth, and they separate visible and infrared light into hundreds of wavelength bands — colors, essentially. Scientists use patterns of reflection and absorption at different wavelengths to determine the composition of what the instrument is observing. The approach echoes Isaac Newton’s prism experiments in 1672, in which the physicist discovered that visible light is composed of a rainbow of colors.
Perched on the International Space Station, NASA’s EMIT can differentiate between types of vegetation to help researchers understand the distribution and traits of plant communities. The instrument collected this data over the mid-Atlantic U.S. on April 23.NASA/JPL-Caltech “Breakthroughs in optics, physics, and chemistry led to where we are today with this incredible instrument, providing data to help address pressing questions on our planet,” said Dana Chadwick, EMIT’s applications lead at NASA’s Jet Propulsion Laboratory in Southern California.
New Science Projects
In its extended mission, EMIT’s data will be the focus of 16 new projects under NASA’s Research Opportunities in Space and Earth Science (ROSES) program, which funds science investigations at universities, research institutions, and NASA.
For example, the U.S. Geological Survey (USGS) and the U.S. Department of Agriculture’s (USDA) Agricultural Research Service are exploring how EMIT can assess climate-smart agricultural practices. Those practices — winter cover crops and conservation tillage — involve protecting cropland during non-growing seasons with either living plants or dead plant matter to prevent erosion and manage nitrogen.
Imaging spectrometers are capable of gathering data on the distribution and characteristics of plants and plant matter, based on the patterns of light they reflect. The information can help agricultural agencies incentivize farmers to use sustainable practices and potentially help farmers manage their fields.
“We’re adding more accuracy and reducing error on the measurements we are supplying to end users,” said Jyoti Jennewein, an Agricultural Research Service research physical scientist based in Fort Collins, Colorado, and a project co-lead.
The USGS-USDA project is also informing analytical approaches for NASA’s future Surface Biology and Geology-Visible Shortwave Infrared mission. The satellite will cover Earth’s land and coasts more frequently than EMIT, with finer spatial resolution.
Looking at Snowmelt
Another new project will test whether EMIT data can help refine estimates of snowpack melting rates. Such an improvement could inform water management in states like California, where meltwater makes up the majority of the agricultural water supply.
Imaging spectrometers like EMIT measure the albedo of snow — the percentage of solar radiation it’s reflecting. What isn’t reflected is absorbed, so the observations indicate how much energy snow is taking in, which in turn helps with estimates of snow melt rates. The instruments also discern what’s affecting albedo: snow-grain size, dust or soot contamination, or both.
For this work, EMIT’s ability to measure beyond visible light is key. Ice is “pretty absorptive at near-infrared and the shortwave infrared wavelengths,” said Jeff Dozier, a University of California, Santa Barbara professor emeritus and the project’s principal investigator.
Other ROSES-funded projects focus on wildflower blooming, phytoplankton and carbon dynamics in inland waters, ecosystem biodiversity, and functional traits of forests.
Dust Impacts
Researchers with EMIT will continue to study the climate effects of dust. When lofted into the air by windstorms, darker, iron-filled dust absorbs the Sun’s heat and warms the surrounding air, while lighter-colored, clay-rich particles do the opposite. Scientists have been uncertain whether airborne dust has overall cooling or warming effects on the planet. Before EMIT, they could only assume the color of particles in a region.
The EMIT mission is “giving us lab-quality results, everywhere we need to know,” said Natalie Mahowald, the mission’s deputy principal investigator and an Earth system scientist at Cornell University in Ithaca, New York. Feeding the data into Earth system computer models, Mahowald expects to get closer to pinpointing dust’s climate impact as Earth warms.
Greenhouse Gas Detection
The mission will continue to identify point-source emissions of methane and carbon dioxide, the greenhouse gases most responsible for climate change, and observations are available through EMIT’s data portal and the U.S. Greenhouse Gas Center.
The EMIT team is also refining the software that identifies and measures greenhouse-gas plumes in the data, and they’re working to streamline the process with machine-learning automation. Aligning with NASA’s open science initiative, they are sharing code with public, private, and nonprofit organizations doing similar work.
“Making this work publicly accessible has fundamentally pushed the science of measuring point-source emissions forward and expanded the use of EMIT data,” said Andrew Thorpe, the JPL research technologist heading the EMIT greenhouse gas effort.
More About EMIT
The EMIT instrument was developed by NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California. Launched to the International Space Station in July 2022, EMIT is on an extended three-year mission in which it’s supporting a range of research projects. EMIT’s data products are available at the NASA Land Processes Distributed Active Archive Center for use by other researchers and the public.

PACE-PAX
PACE–PAX had as its primary objective to gather data to validate measurements from NASA’s PACE mission. A secondary objective was validation of observations by the European Space Agency’s recently launched Earth Cloud, Aerosol, and Radiation Explorer (EarthCARE) mission. The operations spanned Southern and Central California and nearby coastal regions, logging 81 flight hours for the NASA ER-2, which operated out of NASA’s Armstrong Flight Research Center (AFRC) in Edwards, CA, and 60 hours for the Twin Otter aircraft, which was operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) at the Naval Postgraduate School (Monterey, CA) out of Marina Municipal Airport in Marina, CA – see Photo.

The Twin Otter aircraft operated out of the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) during the Plankton, Aerosol, Cloud, ocean Ecosystem–Postlaunch Airborne eXperiment (PACE–PAX) campaign. The image shows the Twin Otter aircraft missing the approach at Marina Airport to check instrument performance on the aircraft against identical instrumentation on an airport control tower. Photo credit: NASA NASA’s ER-2 aircraft flies at an altitude of approximately 20 km, well above the troposphere. PACE–PAX researchers used the unique high-altitude vantage point to make observations of the atmosphere, ocean, and land surface in a similar manner to that of PACE. In so doing, they can verify the accuracy of data gathered by the satellite in orbit. Meanwhile, the Twin Otter flew at a much lower altitude in the atmosphere (~3 km). The instrumentation onboard the Twin Otter was used to sample and measure cloud droplet size, aerosol size, and the amount of light scattered or absorbed by the particles. These aircraft observations are the same atmospheric properties that PACE observes from its broader vantage point in polar orbit. In addition to the PACE and aircraft observations, the R/V Shearwater operated 15 day trips out of Santa Barbara, CA, gathering additional surface-based observations along with other vessels and floats.
Field campaigns, such as PACE–PAX, are designed to collect measurements at different scales and conditions for comparison to satellite observations. When it comes to doing this successfully, timing is everything. PACE–PAX observations were carefully coordinated so that the two aircraft were in flight and taking observations at the same time, so observations were being obtained at the surface (e.g., on the ship) as well as the satellite passing overhead. This takes a tremendous amount of effort on the part of the organizers.
BlueFlux
BlueFlux was set up to study the wetland ecosystems of South Florida. Wetland ecosystems represent the ever-changing line between land and sea, and are exceptionally vulnerable to climate disturbances, such as sea level rise and tropical cyclones. As these threats intensify, wetland ecology – and its role as a critical sink of CO2 – faces an uncertain future.
BlueFlux observations will contribute to the development of a new, remote-sensing data product called “Daily Flux Predictions for South Florida,” which will help research teams led by Ben Poulter [GSFC] explain and quantify the changing relationship between wetlands and atmospheric greenhouse gas concentrations (GHG). The goal is to refine global GHG budget analyses and provide regional stakeholders with information to evaluate how Florida’s wetlands are responding to natural and anthropogenic pressures in real time.
The “Daily Flux Predictions for South Florida” product will use retrievals of surface spectral reflectance captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA’s Aqua and Terra satellites to estimate the rate at which various gasses are exchanged between Earth’s surface and the atmosphere. Such flux measurements in coastal wetlands are historically limited on account of the relative inaccessibility of these ecosystems. To contribute to a more robust understanding of how Florida’s coastal ecology fits into the carbon cycle, BlueFlux conducted a series of airborne fieldwork deployments out of the Miami Homestead Air Reserve Base and the Miami Executive Airport in Miami-Dade County, which are adjacent to the eastern border of the Everglades National Park. The full study region – broadly referred to as South Florida – is narrowly defined by the wetland ecosystems that extend from Lake Okeechobee and its Northern estuaries to the saltwater marshland and mangrove forests along the state’s southernmost shore.
Flux measurements were made along each flight track using a payload known as the CARbon Airborne Flux Experiment (CARAFE) flying at between about 90 m and 3000 m. The researchers configured airborne observations, along with additional ground-based flux measurements, to match the spatial and temporal resolution of spectra collected by MODIS sensors, which produce surface reflectance retrievals at a 500 m daily resolution. Mirroring the scale of MODIS observations was necessary to both train the flux product’s underlying machine-learning algorithms and validate the accuracy of predictions made using satellite data alone. Data collected during BlueFlux fieldwork campaigns is available to the general public through NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The “Daily Flux Predictions for South Florida” data product will also be accessible through NASA’s ORNL DAAC by early 2025.
