SUPPORTThe Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) is a planned two-year mission that will survey the sky in optical as well as near-infrared light which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions. Astronomers will use the mission to gather data on more than 450 million galaxies, as well as, more than 100 million stars in our own Milky Way.
SPHEREx will survey hundreds of millions of galaxies near and far, some so distant their light has taken 10 billion years to reach Earth. In the Milky Way, the mission will search for water and organic molecules - essentials for life, as we know it - in stellar nurseries, regions where stars are born from gas and dust, as well as disks around stars where new planets could be forming.
Every six months, SPHEREx will survey the entire sky using technologies adapted from Earth satellites and interplanetary spacecraft. The mission will create a map of the entire sky in 96 different color bands, far exceeding the color resolution of previous all-sky maps. It also will identify targets for more detailed study by future missions, such as NASA's James Webb Space Telescope and Wide Field Infrared Survey Telescope.
SPHEREx PI Dr. Jamie Bock leads the investigation. The California Institute of Technology and Jet Propulsion Laboratory will develop the SPHEREx payload. The spacecraft will be supplied by Ball Aerospace. The Korea Astronomy and Space Science Institute will contribute the non-flight cryogenic test chamber. The data will be made publicly available through the Infrared Processing and Analysis Center. In addition to the Caltech/JPL and international scientists, the SPHEREx team includes scientists at institutions across the country, including UC Irvine, Ohio State University, the Harvard-Smithsonian Center for Astrophysics, Arizona State University, the University of Arizona, Rochester Institute of Technology, Argonne National Laboratory, and Johns Hopkins University.

NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission is a constellation of four small satellites in Sun-synchronous, low Earth orbit that will make global, 3D observations of the young solar wind, from the outermost solar atmosphere to the inner heliopshere. Images of unprecedented quality will help to close a 60-year gap in measurements of understanding of what occurs in this region of space.

Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond.
Falcon 9 is the world’s first orbital-class reusable rocket.
Stats
Total launches: 387
Total landings: 343
Total reflights: 318
The Falcon 9 has launched 52 humans into orbit since May 2020
Specs
Height: 70 m / 229.6 ft
Diameter: 3.7 m / 12 ft
Mass: 549,054 kg / 1,207,920 lb
Payload to Low Earth Orbit (LEO): 22,800 kg / 50,265 lb
Payload to Geostationary Transfer Orbit (GTO): 8,300 kg / 18,300 lb
Payload to Mars: 4,020 kg / 8,860 lb
On January 24, 2021, Falcon 9 launched the first ride-share mission to Sun Synchronous Orbit. It was delivering a record-setting 143 satellites to space. And while this was an important mission for SpaceX in itself, it was also the moment Falcon 9 overtook United Launch Alliance’s Atlas V for the total number of consecutive successful launches.
SpaceX’s Falcon 9 had become America’s workhorse rocket, launching 31 times in 2021. It has already beaten that record this year, launching almost an average of once a week. While most of the launches deliver Starlink satellites to orbit, the company is still launching the most commercial payloads to orbit, too.
Falcon 9 is a medium-lift launch vehicle, with the capability to launch over 22.8 metric tonnes to low earth orbit. Unlike any other rocket, its first stage lands back on Earth after separating from its second stage. In part, this allows SpaceX to offer the cheapest option for most customers with payloads that need to reach orbit.
Under its ride-share program, a kilogram can be placed in a sun-synchronous orbit for a mere 1.1 million dollars, far cheaper than all other currently operating small satellite launch vehicles.
The reusability and fast booster turnaround times have made Falcon 9 the preferred choice for private companies and government agencies. This has allowed SpaceX to capture a huge portion of the launch market.

Space Launch Complex 4 (SLC-4) at Vandenberg Space Force Base is SpaceX’s west coast launch and landing facility, with its launch pad designated SLC-4E (the eastern-most of the two areas). Originally built in the early 1960s for Atlas-Agena rockets, the pad served that rocket line until 1967, when it was taken offline and rebuilt for Titan IIID rockets. From 1971 to 1988, SLC-4E launched Titan IIID rockets, after which it was reconfigured for Titan IV missions, which continued between 1991 and 2005.
In 2011, SpaceX leased SLC-4E and spent two years rebuilding the pad for its Falcon 9 rocket. From 2013 to 2019, the pad exclusively supported Falcon 9 polar missions. However, in 2020, SpaceX began splitting polar launches between Vandenberg and Cape Canaveral, after the Air Force lifted a 51-year ban on Florida-based polar launches, previously imposed due to the risk of overflying Cuba during launch. Despite these new opportunities from Florida, SpaceX plans to continue utilizing Vandenberg, with many more launches scheduled from this location.

"Of Course I Still Love You" (OCISLY) is one of SpaceX’s Autonomous Spaceport Drone Ships used to recover Falcon 9 rocket boosters from the ocean. Like its sister ships, "Just Read the Instructions" (JRTI) and "A Shortfall of Gravitas" (ASOG), OCISLY plays a crucial role in SpaceX’s reusability program, which aims to make spaceflight more cost-effective and sustainable.
The name "Of Course I Still Love You" is inspired by science fiction author Iain M. Banks' Culture series, known for its imaginative and whimsical ship names. This naming theme extends to SpaceX's other drone ships.
OCISLY originally operated in the Atlantic Ocean, primarily from Cape Canaveral, Florida. It has since been retired and replaced by ASOG in the Atlantic, with its operations shifting to the Pacific Ocean.
Equipped with advanced navigation systems and thrusters for precise positioning, OCISLY featured a large landing platform designed for recovering rocket boosters at sea. It was instrumental in supporting missions where boosters couldn’t return to solid ground, enabling SpaceX to reuse rocket stages and contribute to lowering costs and improving the sustainability of space missions.
