      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s SPHEREx observatory undergoes integration and testing at BAE Systems in Boulder, Colorado, in April 2024. The space telescope will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors. BAE Systems The space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color.
      NASA’s SPHEREx mission won’t be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors. Although these colors aren’t visible to the human eye because they’re in the infrared range, scientists will use them to learn about topics that range from the physics that governed the universe less than a second after its birth to the origins of water on planets like Earth.
      “We are the first mission to look at the whole sky in so many colors,” said SPHEREx Principal Investigator Jamie Bock, who is based jointly at NASA’s Jet Propulsion Laboratory and Caltech, both in Southern California. “Whenever astronomers look at the sky in a new way, we can expect discoveries.”
      Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will collect infrared light, which has wavelengths slightly longer than what the human eye can detect. The telescope will use a technique called spectroscopy to take the light from hundreds of millions of stars and galaxies and separate it into individual colors, the way a prism transforms sunlight into a rainbow. This color breakdown can reveal various properties of an object, including its composition and its distance from Earth.
      NASA’s SPHEREx mission will use spectroscopy — the splitting of light into its component wavelengths — to study the universe. Watch this video to learn more about spectroscopy. NASA’s Goddard Space Flight Center Here are the three key science investigations SPHEREx will conduct with its colorful all-sky map.
      Cosmic Origins
      What human eyes perceive as colors are distinct wavelengths of light. The only difference between colors is the distance between the crests of the light wave. If a star or galaxy is moving, its light waves get stretched or compressed, changing the colors they appear to emit. (It’s the same with sound waves, which is why the pitch of an ambulance siren seems to go up as its approaches and lowers after it passes.) Astronomers can measure the degree to which light is stretched or compressed and use that to infer the distance to the object.
      SPHEREx will apply this principle to map the position of hundreds of millions of galaxies in 3D. By doing so, scientists can study the physics of inflation, the event that caused the universe to expand by a trillion-trillion fold in less than a second after the big bang. This rapid expansion amplified small differences in the distribution of matter. Because these differences remain imprinted on the distribution of galaxies today, measuring how galaxies are distributed can tell scientists more about how inflation worked.
      Galactic Origins
      SPHEREx will also measure the collective glow created by all galaxies near and far — in other words, the total amount of light emitted by galaxies over cosmic history. Scientists have tried to estimate this total light output by observing individual galaxies and extrapolating to the trillions of galaxies in the universe. But these counts may leave out some faint or hidden light sources, such as galaxies too small or too distant for telescopes to easily detect.
      With spectroscopy, SPHEREx can also show astronomers how the total light output has changed over time. For example, it may reveal that the universe’s earliest generations of galaxies produced more light than previously thought, either because they were more plentiful or bigger and brighter than current estimates suggest. Because light takes time to travel through space, we see distant objects as they were in the past. And, as light travels, the universe’s expansion stretches it, changing its wavelength and its color. Scientists can therefore use SPHEREx data to determine how far light has traveled and where in the universe’s history it was released.
      Water’s Origins
      SPHEREx will measure the abundance of frozen water, carbon dioxide, and other essential ingredients for life as we know it along more than 9 million unique directions across the Milky Way galaxy. This information will help scientists better understand how available these key molecules are to forming planets. Research indicates that most of the water in our galaxy is in the form of ice rather than gas, frozen to the surface of small dust grains. In dense clouds where stars form, these icy dust grains can become part of newly forming planets, with the potential to create oceans like the ones on Earth.
      The mission’s colorful view will enable scientists to identify these materials, because chemical elements and molecules leave a unique signature in the colors they absorb and emit.
      Big Picture
      Many space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply spectroscopy to the entire sky.
      By combining observations from telescopes that target specific parts of the sky with SPHEREx’s big-picture view, scientists will get a more complete — and more colorful — perspective of the universe.
      More About SPHEREx
      SPHEREx is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate 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 across the U.S. and in South Korea. 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.

      Connected Learning Ecosystems: Educators Learning and Growing Together
      On August 19-20, 53 educators from a diverse set of learning contexts (libraries, K-12 classrooms, 4-H afterschool clubs, outdoor education centers, and more) gathered in Orono, Maine for the Learning Ecosystems Northeast (LENE) biannual Connect, Reflect, & Plan Connected Learning Ecosystems (CLEs) Gathering. These gatherings are meant to foster meaningful connections and collaborations and shared knowledge and confidence building amongst educators within the LENE network.
      NASA Science Activation’s Learning Ecosystems Northeast (LENE) is a network of education partners across the Northeastern United States, led by the Gulf of Maine Research Institute. These partners are dedicated to creating and linking communities of in and out of school educators, Connected Learning Ecosystems (CLEs), who are committed to empowering the next generation of climate stewards.
      The focus of this gathering was to provide educators the time, experiences, connections, and space to explore ways they can prepare the youth and communities they work with to build resilience in the face of climate change. Educators participated in sessions around local asset mapping, climate mental health, positive youth development, building STEM skills through games and fieldwork, and planning forward around coastal flooding and sea level rise. Each session was followed by time to debrief, reflect, and plan both in their regional CLEs as well as with statewide partners. The value of NASA assets and connection to local issues was woven throughout many experiences during this gathering. LENE’s CLE Resource Drive has a growing list of phenomena-based NASA assets that has been curated based on the interests of their network over time. The Global Learning and Observations to Benefit the Environment (GLOBE) program’s GLOBE Observer tree height app was part of the Ash Protection community science protocol and many NASA assets enhance the educator-guided planning forward experience guide that youth practice the difficult, real-life conversations about the
      consequences of sea level rise as they think about ways they can plan for a resilient future in the face of rising seas and coastal flooding.
      Sara King from the Rural Aspirations Project (Hancock/Midcoast CLE) had this to say: “Before I first joined the CLE, I viewed STEM professionals to be separate from myself for the most part because I did not feel very confident in my abilities in all parts of STEM. I feel more comfortable with data and technology, engineering, and science practices now.”
      One educator said that their highlight from the gathering was, “[o]pportunities to meet with other teachers and educators and librarians to share ideas about how we can pool our resources and reach more students.” These educators left with draft learning projects ready for refinement and review, renewed dedication and motivation for the school year, and new perspectives to lead them into continued conversations and partnership with their CLE peers as they meet throughout the year.
