Sharing PLANETS Curriculum with Out-of-School Time Educators
Out of school time (OST) educators work with youth in afterschool, community, and camp programs. Science, Technology, Engineering, and Mathematics (STEM) learning in OST can be challenging for multiple reasons, including lack of materials and support for educators. The NASA Science Activation program’s PLANETS project – Planetary Learning that Advances the Nexus of Engineering, Technology, and Science – led by Northern Arizona University in Flagstaff, AZ, provides both written curriculum and virtual educator support on planetary science and engineering.
PLANETS offers three curriculum units focused on themes from NASA’s strategic priorities and mission directives in planetary science over the next decade:
Space Hazards for learners in grades 3-5, Water in Extreme Environments, and Remote Sensing for learners in grades 6-8. PLANETS recently exhibited at two national conferences for educators to share these free NASA partner resources: the Space Exploration Educators Conference at Space Center Houston in Houston, TX on Feb 6-8, 2025 and the Beyond School Hours conference in Orlando, FL on Feb 13-16, 2025. Approximately 500 educators interacted with PLANETS team members to learn about the curriculum and to share their needs for OST learners. Some educators shared how they are already using PLANETS and how much their learners enjoy the lessons. In addition to sharing PLANETS resources, the team also had QR codes and flyers providing information about all the other Science Activation project teams, making sure educators grow in awareness of all that NASA’s Science Mission Directorate does to engage the public.
OST educators appreciate the integrity and quality of NASA-funded resources. One educator shared, “Free resources are always critical to youth-serving organizations. PLANETS also has everyday materials and educator dialogue on how to deliver, making it easy to pick up and use.”
Another OST educator said, “There are programs out there, like PLANETS, that truly help people of all backgrounds,” and yet another expressed, “I love the activities, and could see our youth engaging with it in a fun way.” Disseminating these types of NASA Science Activation program resources at regional and national venues is vital.
The PLANETS project is supported by NASA under cooperative agreement award number NNX16AC53A and is part of NASA’s Science Activation Portfolio.

Credit: NASA NASA has selected SpaceX of Starbase, Texas, to provide launch services for the Near-Earth Object (NEO) Surveyor mission, which will detect and observe asteroids and comets that could potentially pose an impact threat to Earth.
The firm fixed price launch service task order is being awarded under the indefinite delivery/indefinite quantity NASA Launch Services II contract. The total cost to NASA for the launch service is approximately $100 million, which includes the launch service and other mission related costs. The NEO Surveyor mission is targeted to launch no earlier than September 2027 on a SpaceX Falcon 9 rocket from Florida.
The NEO Surveyor mission consists of a single scientific instrument: an almost 20-inch (50-centimeter) diameter telescope that will operate in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, the latter being the most difficult type to find with existing assets. The space telescope is designed to help advance NASA’s planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-Earth objects, or NEOs.
The mission will carry out a five-year baseline survey to find at least two-thirds of the unknown NEOs larger than 140 meters (460 feet). These are the objects large enough to cause major regional damage in the event of an Earth impact. By using two heat-sensitive infrared imaging channels, the telescope can also make more accurate measurements of the sizes of NEOs and gain information about their composition, shapes, rotational states, and orbits.
The mission is tasked by NASA’s Planetary Science Division within the agency’s Science Mission Directorate at NASA Headquarters in Washington. Program oversight is provided by NASA’s Planetary Defense Coordination Office, which was established in 2016 to manage the agency’s ongoing efforts in planetary defense. NASA’s Planetary Missions Program Office at the agency’s Marshall Space Flight Center in Huntsville, Alabama, provides program management for NEO Surveyor. The project is being developed by NASA’s Jet Propulsion Laboratory in Southern California.
Multiple aerospace and engineering companies are contracted to build the spacecraft and its instrumentation, including BAE Systems SMS (Space & Mission Systems), Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, will support operations, and the Infrared Processing and Analysis Center at the California Institute of Technology (Caltech) in Pasadena, California, is responsible for processing survey data and producing the mission’s data products. Caltech manages JPL for NASA. Mission team leadership includes the University of California, Los Angeles. NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida is responsible for managing the launch service.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s SPHEREx mission will survey the Milky Way galaxy looking for water ice and other key ingredients for life. In the search for these frozen compounds, the mission will focus on molecular clouds — collections of gas and dust in space — like this one imaged by the agency’s James Webb Space Telescope. NASA, ESA, CSA Where is all the water that may form oceans on distant planets and moons? The SPHEREx astrophysics mission will search the galaxy and take stock.
Every living organism on Earth needs water to survive, so scientists searching for life outside our solar system, are often guided by the phrase “follow the water.” Scheduled to launch no earlier than Thursday, Feb. 27, NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission will help in that quest.
After its ride aboard a SpaceX Falcon 9 from Vandenberg Space Force base in California, the observatory will search for water, carbon dioxide, carbon monoxide, and other key ingredients for life frozen on the surface of interstellar dust grains in the clouds of gas and dust where planets and stars eventually form.
While there are no oceans or lakes floating freely in space, scientists think these reservoirs of ice, bound to small dust grains, are where most of the water in our universe forms and resides. Additionally, the water in Earth’s oceans as well as those of other planets and moons in our galaxy likely originated in such locations.
The Perseus Molecular Cloud, located about 1,000 light-years from Earth, was imaged by NASA’s retired Spitzer Space Telescope. NASA’s SPHEREx mission will search the galaxy for water ice and other frozen compounds in clouds of gas and dust in space like this one. NASA/JPL-Caltech The mission will focus on massive regions of gas and dust called molecular clouds. Within those, SPHEREx will also look at some newly formed stars and the disks of material around them from which new planets are born.
Although space telescopes such as NASA’s James Webb and retired Spitzer have detected water, carbon dioxide, carbon monoxide, and other compounds in hundreds of targets, the SPHEREx observatory is the first to be uniquely equipped to conduct a large-scale survey of the galaxy in search of water ice and other frozen compounds.
Get the SPHEREx Press Kit Rather than taking 2D images of a target like a star, SPHEREx will gather 3D data along its line of sight. That enables scientists to see the amount of ice present in a molecular cloud and observe how the composition of the ices throughout the cloud changes in different environments.
By making more than 9 million of these line-of-sight observations and creating the largest-ever survey of these materials, the mission will help scientists better understand how these compounds form on dust grains and how different environments can influence their abundance.
Tip of the Iceberg
It makes sense that the composition of planets and stars would reflect the molecular clouds they formed in. However, researchers are still working to confirm the specifics of the planet formation process, and the universe doesn’t always match scientists’ expectations.
For example, a NASA mission launched in 1998, the Submillimeter Wave Astronomy Satellite (SWAS), surveyed the galaxy for water in gas form — including in molecular clouds — but found far less than expected.
BAE Systems employees work on NASA’s SPHEREx observatory in the Astrotech Space Operations facility at Vandenberg Space Force Base in California on Jan. 16. Targeting a Feb. 27 launch, the mission will map the entire sky in infrared light. NASA/JPL-Caltech “This puzzled us for a while,” said Gary Melnick, a senior astronomer at the Center for Astrophysics | Harvard & Smithsonian and a member of the SPHEREx science team. “We eventually realized that SWAS had detected gaseous water in thin layers near the surface of molecular clouds, suggesting that there might be a lot more water inside the clouds, locked up as ice.”
The mission team’s hypothesis also made sense because SWAS detected less oxygen gas (two oxygen atoms bound together) than expected. They concluded that the oxygen atoms were sticking to interstellar dust grains, and were then joined by hydrogen atoms, forming water. Later research confirmed this. What’s more, the clouds shield molecules from cosmic radiation that would otherwise break those compounds apart. As a result, water ice and other materials stored deep in a cloud’s interior are protected.
As starlight passes through a molecular cloud, molecules like water and carbon dioxide block certain wavelengths of light, creating a distinct signature that SPHEREx and other missions like Webb can identify using a technique called absorption spectroscopy.
In addition to providing a more detailed accounting of the abundance of these frozen compounds, SPHEREx will help researchers answer questions including how deep into molecular clouds ice begins to form, how the abundance of water and other ices changes with the density of a molecular cloud, and how that abundance changes once a star forms.
Powerful Partnerships
As a survey telescope, SPHEREx is designed to study large portions of the sky relatively quickly, and its results can be used in conjunction with data from targeted telescopes like Webb, which observe a significantly smaller area but can see their targets in greater detail.
“If SPHEREx discovers a particularly intriguing location, Webb can study that target with higher spectral resolving power and in wavelengths that SPHEREx cannot detect,” said Melnick. “These two telescopes could form a highly effective partnership.”
More About SPHEREx
SPHEREx is managed by NASA’s Jet Propulsion Laboratory in Southern California for the Astrophysics Division within the Science Mission Directorate at NASA Headquarters in Washington. BAE Systems (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions in the U.S., two in South Korea, and one in Taiwan. Data will be processed and archived at IPAC at Caltech, which manages JPL for NASA. The mission principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset will be publicly available at the NASA/IPAC Infrared Science Archive.

Arcand A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus.
By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the Atacama Large Millimeter/submillimeter Array (orange), this stellar arrangement comes alive.
X-ray: NASA/CXC/Penn State Univ./L. Townsley et al.; Infrared: NASA/JPL-CalTech/SST; Optical: NASA/STScI/HST; Radio: ESO/NAOJ/NRAO/ALMA; Image Processing: NASA/CXC/SAO/J. Schmidt, N. Wolk, K. Arcand Otherwise known as the Tarantula Nebula, 30 Dor is located about 160,000 light-years away in a small neighboring galaxy to the Milky Way known as the Large Magellanic Cloud (LMC). Because it one of the brightest and populated star-forming regions to Earth, 30 Dor is a frequent target for scientists trying to learn more about how stars are born.
With enough fuel to have powered the manufacturing of stars for at least 25 million years, 30 Dor is the most powerful stellar nursery in the local group of galaxies that includes the Milky Way, the LMC, and the Andromeda galaxy.
The massive young stars in 30 Dor send cosmically strong winds out into space. Along with the matter and energy ejected by stars that have previously exploded, these winds have carved out an eye-catching display of arcs, pillars, and bubbles.
A dense cluster in the center of 30 Dor contains the most massive stars astronomers have ever found, each only about one to two million years old. (Our Sun is over a thousand times older with an age of about 5 billion years.)
This new image includes the data from a large Chandra program that involved about 23 days of observing time, greatly exceeding the 1.3 days of observing that Chandra previously conducted on 30 Dor. The 3,615 X-ray sources detected by Chandra include a mixture of massive stars, double-star systems, bright stars that are still in the process of forming, and much smaller clusters of young stars.
There is a large quantity of diffuse, hot gas seen in X-rays, arising from different sources including the winds of massive stars and from the gas expelled by supernova explosions. This data set will be the best available for the foreseeable future for studying diffuse X-ray emission in star-forming regions.
The long observing time devoted to this cluster allows astronomers the ability to search for changes in the 30 Dor’s massive stars. Several of these stars are members of double star systems and their movements can be traced by the changes in X-ray brightness.
A paper describing these results appears in the July 2024 issue of The Astrophysical Journal Supplement Series. NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release features a highly detailed composite image of a star-forming region of space known as 30 Doradus, shaped like a bouquet, or a maple leaf.
30 Doradus is a powerful stellar nursery. In 23 days of observation, the Chandra X-ray telescope revealed thousands of distinct star systems. Chandra data also revealed a diffuse X-ray glow from winds blowing off giant stars, and X-ray gas expelled by exploding stars, or supernovas.
In this image, the X-ray wind and gas takes the shape of a massive purple and pink bouquet with an extended central flower, or perhaps a leaf from a maple tree. The hazy, mottled shape occupies much of the image, positioned just to our left of center, tilted slightly to our left. Inside the purple and pink gas and wind cloud are red and orange veins, and pockets of bright white light. The pockets of white light represent clusters of young stars. One cluster at the heart of 30 Doradus houses the most massive stars astronomers have ever found.
The hazy purple and pink bouquet is surrounded by glowing dots of green, white, orange, and red. A second mottled purple cloud shape, which resembles a ring of smoke, sits in our lower righthand corner.
