What is the Vandenberg Space Force Base? 4 things to know about California rocket launches
When spaceflight enthusiasts think about catching a rocket launch, the first place to come to mind, more than likely, is Florida. The Sunshine State is brimming with a near-constant schedule of crewed and uncrewed launches from NASA's Kennedy Space Center and Cape Canaveral Space Force Station, both located on Florida's Space Coast. Catching the sight of a SpaceX or NASA vehicle getting off the ground has become so popular among tourists, that the U.S. space agency even sells tickets for spectators. But all the way across the U.S. on the West Coast, plenty of spaceflights are launching from California. In Santa Barbara County, a military base regularly hosts rocket launches that span the civil and commercial arenas. Rocket launches have become so well-known that spectators have established popular locations in both Southern California and neighboring Arizona to watch the spacecraft soar into orbit. Here's everything to know about the Vandenberg Space Force Base, the only site for rocket launches in California. California rocket launches: Here's a look at the upcoming schedule from Vandenberg The Vandenberg Space Force Base is a rocket launch site in Santa Barbara County in Southern California. Established in 1941, the site was previously known as the Vandenberg Air Force Base. Though it's a military base, the site also hosts both civil and commercial space launches for entities like NASA and SpaceX. Space Launch Delta 30, a unit of the U.S. Space Force, is responsible for managing the launch operations at Vandenberg, as well as the missile tests that take place at the base. Vandenberg hosts a regular cadence of weekly rocket launches, most from its Space Launch Complex 4 East (SLC-4E.) In the month of May, a total of six launches got off the ground from Vandenberg, all of which were SpaceX missions to deploy Starlink internet satellites into orbit. This year, the Federal Aviation Administration, which licenses commercial rocket launches, gave SpaceX the greenlight to increase its Falcon 9 rocket launches from Vandenberg from 36 per year to 50. But it's not just SpaceX that launches from Vandenberg. In March, NASA contracted a SpaceX Falcon 9 rocket to boost both its SPHEREx space telescope and small sun-observing PUNCH satellites into orbit following a launch from the base. And in late-April, Texas spaceflight company Firefly Aerospace attempted to launch prototype satellites into orbit for Lockheed Martin from the base. SpaceX's Starlink missions have become by far the most frequent and common rocket launches from Southern California. Two Starlink deployments have taken place so far in June, with a third and fourth on the way in less than a week. The company's Famous two-stage Falcon 9 rocket, one of the world's most active, has become crucial in regularly deploying batches of the internet-beaming Starlink satellites into what's called low-Earth orbit – an altitude that allows for things like satellites to circle Earth fairly quickly. Owned by SpaceX founder Elon Musk, Starlink is a constellation of more than 7,000 satellites that provide internet service to customers around the world. SpaceX has spent more than six years delivering the satellites to orbit with a regular cadence of rocket launches from both Florida and California. Following the delivery and deployment of the satellites from California, the Falcon 9 rocket's booster aims to land on a SpaceX drone ship, nicknamed "Of Course I Still Love You," in the Pacific Ocean. This allows for SpaceX personnel to recover the booster so it can be reused in future spaceflights. Because Vandenberg is an active military base, the launch complex does not host public viewings of launches. But if conditions are clear, rocket launches from the Vandenberg Space Force Base can be viewed from several locations as far as Santa Barbara and Los Angeles. The city of Lompoc in Santa Barbara County is filled with places to catch a rocket launch. The city's tourism bureau, Explore Lompoc, even maintains a list with suggested viewing locations.

In Photos: See The Stunning ‘Space Rainbows' Captured By NASA
On April 18, 2025, the WFI-2 instrument on NASA's PUNCH spacecraft created this view of the zodiacal ... More light, a faint glow from dust orbiting the sun. There are no rainbows in space, but the next best thing has been snapped by a new NASA spacecraft now orbiting Earth while testing its cameras. The spacecraft, called PUNCH (Polarimeter to Unify the Corona and Heliosphere), is about to begin investigating how the sun's outer corona — by far the hottest part of our star's atmosphere — becomes the solar wind that causes the Northern Lights. The PUNCH mission blasted off on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on March 11, 2025. Also in the rocket's fairing was NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory. PUNCH isn't a single spacecraft. It comprises four small satellites that together create a single 'virtual instrument' that spans the whole PUNCH constellation. The aim is to make 3D observations of the sun's corona for at least two years. It's hoped that by doing so, scientists will better be able to figure out how the sun's corona becomes the solar wind and so more accurately predict space weather. That's crucial because solar wind can greatly affect satellites and robotic explorers in space. Captured on April 16, 2025, this is the first image taken by PUNCH's WFI-1 instrument. The ... More instrument's wide field of view reveals the glow of zodiacal light stretching up and to the right. The V shape of the Hyades star cluster appears near the top, with the more compact Pleiades star cluster to the lower right. A rainbow is an optical illusion created by sunlight refracting and being reflected inside droplets of liquid in an atmosphere. That's not going to happen in space. PUNCH's 'space rainbows' are unique images of what astronomers call the zodiacal light, a triangular beam of light that can be seen on the horizon a few hours before sunrise or after sunset as the false dawn or false dusk. PUNCH's stunning polarimetric triplet images are a combination of three images (red, green and blue) of sunlight being reflected by space dust. They were created during imaging tests of three polarizers on PUNCH on April 18, 2025, with the light colorized based on its angle (polarization). For a few weeks in late September and October, a triangular beam of light appears on the eastern horizon a few hours before sunrise before gently fading. This is the "false dawn." In March and April, the opposite happens as a triangular beam of light appears on the western horizon a few hours after sunset — the "false dusk." So-called zodiacal light — literally "light from the circle of animals" — is the glow of the solar system. Reflected sunlight from interplanetary dust around the sun between the orbits of Mars and Jupiter radiates across the (visible) optical spectrum and beyond. Depictions of two kinds of dust in space: At left the pyramid-shaped glow of Zodiacal Light caused ... More by sunlight reflecting off interplanetary dust in the inner solar system from comets and meteoroids, while at right is the band of the bright Milky Way, made of stars in our galaxy. (Photo by: VW Pics/Universal Images Group via Getty Images) It's called the zodiacal light because it appears above where the sun has just set/is about to rise, so along the ecliptic — the path of the sun through the daytime sky. This is the plane of the solar system, and it's where you'll find the belt of constellations across the night sky that the sun moves through in a calendar year — hence star signs. The 12 'signs' of the zodiac are all officially recognized astronomical constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. There's also a thirteenth, Ophiuchus, a huge constellation that the sun also passes through. Wishing you clear skies and wide eyes.

NASA's PUNCH spacecraft see a cosmic rainbow in the zodiacal light
When you buy through links on our articles, Future and its syndication partners may earn a commission. NASA's newest spacecraft aimed at studying the sun have captured a colorful "rainbow" in the warm glow of zodiacal light observed above Earth. The PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which launched on March 11, consists of four small satellites working in unison in low Earth orbit to provide a comprehensive view of the sun's corona, or outer atmosphere, and study the constant stream of charged particles emitted by the sun known as solar wind. The mission delivered its first set of images, including a vivid, rainbow-colored view of the sky, according to a statement from NASA that shared PUNCH's latest images. These images feature zodiacal light — the faint, diffuse glow created by sunlight scattering off dust particles in space. In one view captured by the PUNCH mission's WFI-2 instrument on April 18, a hazy glow transitions from red on the left to green in the center and blue on the right, set against a backdrop of stars. The coloration of light in this image does not depict a true optical rainbow as would be seen by the naked eye, but rather a colored representation of different wavelengths of light that highlight the instrument's capability to analyze various components of the solar atmosphere. The mission measures the corona and solar wind in three dimensions by studying the polarization of light, which is the direction light travels after it has been scattered by particles. The four satellites include one Narrow Field Imager (NFI), which blocks out the bright light from the sun to better see details in the corona. On April 27, the NFI instrument captured the new moon as it passed by the sun, using its occulter (an object that blocks a direct view of the sun) to hide the solar disk. These early images help the PUNCH mission team calibrate the instruments and ensure they are working as expected. The PUNCH spacecraft also include three Wide Field Imagers (WFIs), which are designed to see the very faint, outermost portion of the corona and solar wind. The WFI-1 and WFI-3 instruments also captured the soft glow of zodiacal light on April 16, with the Hyades and Pleiades star clusters and Andromeda galaxy in view. The Andromeda galaxy can be seen as a faint wispy spiral on the far right of the image below. The 'W' shape of the Cassiopeia constellation can be made out at the top. The familiar Pleiades can be seen at the left side of the image. RELATED STORIES: — NASA's sun-studying PUNCH mission captures its 1st-light images.

Unlike the James Webb Space Telescope, however, SPHEREx is designed to take in a wide view of the universe in order to create a new map of the visible sky. "We are literally mapping the entire celestial sky in 102 infrared colors for the first time in humanity's history," Nicky Fox, associate administrator for NASA's Science Mission Directorate, said during a conference about SPHEREx on Jan. 31.

NASA SPHEREx space telescope has captured its 1st images of cosmos: See stunning photos
NASA's newest space telescope has officially begun snapping some incredible images of the cosmos about two months after it got off the ground. SPHEREx, which the U.S. space agency sent on a mission to unravel some of the universe's biggest mysteries, first released a debut batch of uncalibrated images in April unsuited for scientific study. What followed was about six weeks of procedures to make sure the advanced instrument is working as it should. Now, the telescope has commenced mapping not just a section of the sky, but all of it as part of NASA's goal of charting the positions of hundreds of millions of galaxies in three-dimension. As of May, that includes taking some 3,600 images per day. NASA released a sampling of those images May 1, which the space agency hopes are just the tip of the iceberg. Ultimately, scientists hope SPHEREx will provide data lending new insights into the origins of the universe and whether the ingredients for life exist anywhere else in our Milky Way galaxy. Here's a look at some of SPHEREx's first images, as well as what to know about the observatory's two-year mission. SPHEREx mission: NASA launches 'incredible' new tools into space to study the universe, sun's corona See 1st photos from SPHEREx space telescope Throughout the next 25 months, the SPHEREx observatory will orbit Earth more than 11,000 times while surveying and imaging the surrounding sky. When SPHEREx takes pictures of the sky, the light is sent to six detectors that can capture different wavelengths of light, or exposures. By the mission's end, NASA will weave hundreds of thousands of SPHEREx's images into digital sky maps. Here's a look at two of the newest photos: What is the SPHEREx mission? Telescope to study origins of universe SPHEREx, short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, was developed by NASA for a mission to uncover some of the universe's greatest mysteries. The advanced observatory, an 8½ foot-tall cone-shaped telescope with infrared capabilities, will create a 3D map of the entire celestial sky every six months. SPHEREx will also use a technique called spectroscopy to measure the distance to 450 million galaxies in the nearby universe. Astronomers theorize that the distribution of the galaxies was influenced by a universe-expanding event that took place almost 14 billion years ago after the big bang. During its mission, the telescope will also measure the glow of all the galaxies in the universe, which should provide new insights into how galaxies formed and evolved over cosmic time. But the mission isn't only studying faraway galaxies. SPHEREx will also turn its attention to our Milky Way to search for hidden reservoirs of frozen water ice and other molecules, like carbon dioxide, that are essential to life as we know it. When and where did the SPHEREx telescope launch? The telescope got off the ground March 12 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in Vandenberg, California. The space observatory shared a ride with the four small satellites that make up NASA's PUNCH mission, which will study how the sun's outer atmosphere becomes solar wind. The two missions are designed to operate in low-Earth orbit in such a way that the sun always remains in the same position relative to each spacecraft. This is essential for SPHEREx to keep its telescope shielded from the sun's light and heat, which would inhibit its observations, and for PUNCH to have a clear view in all directions around the sun, according to NASA. How is SPHEREx different from James Webb Space Telescope, Hubble Space Telescope? NASA believes SPHEREx could complement the famous Hubble and James Webb space telescopes, which have for years already been studying the far corners of the known universe. Hubble and Webb specialize in zooming in on small areas in great detail, unveiling planets, stars and galaxies in high resolution. But some questions "can be answered only by looking at the big picture," according to NASA. That's where SPHEREx comes in. The new telescope could help fill in the gap by getting a wider view of the galaxy – identifying objects of scientific interest that telescopes like Hubble and Webb can then go study up close. The result would provide scientists with a more complete perspective of the universe, according to NASA. Eric Lagatta is the Space Connect reporter for the USA TODAY Network.

NASA's SPHEREx space telescope has begun its mission to map the entire sky in 3D
A space observatory designed to map the entire sky over a period of two years to further our understanding of the early universe has started snapping images. SPHEREx, which launched in early March, got started with its observations this past week after over a month of setup procedures and system checks, according to NASA. The space telescope will complete about 14.5 orbits of Earth per day, capturing roughly 3,600 images daily and observing the sky in an unprecedented 102 wavelengths of infrared light. Its observations will eventually be combined to create four 'all-sky' maps. SPHEREx's 25 month survey will be a comprehensive one. The spacecraft 'orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky,' NASA explains. 'As the days pass and the planet moves around the Sun, SPHEREx's field of view shifts as well so that after six months, the observatory will have looked out into space in every direction.' Researchers will use the SPHEREx observations to study the universe's expansion in the moments after the big bang, and search for the ingredients for life elsewhere in the Milky Way.
