SPHEREx

Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer.

About the size of a subcompact car, SPHEREx will enter a polar orbit around Earth and create a map of the entire sky in 3D, taking images in every direction, like scanning the inside of a globe. The map will contain hundreds of millions of stars and galaxies, showing them in 102 colors (each a different wavelength of light).

Scientists will use SPHEREx’s all-sky map to achieve the mission’s three key science goals. The first is to shed light on a cosmic phenomenon called inflation, a brief but powerful cosmic event when space itself increased in size by a trillion-trillionfold less than a second after the big bang. The observatory will measure the distribution of hundreds of millions of galaxies to improve understanding of what drove inflation and of the physics behind this event.

The SPHEREx mission will also measure the collective glow from galaxies near and far, including light from hidden galaxies that haven’t been individually observed. This data will provide a more complete picture of all the objects and sources radiating in the universe.

Its third key science goal is to search the Milky Way galaxy for icy granules of water, carbon dioxide, and other essential building blocks of life. The mission will help scientists discover the location and abundance of these icy compounds in our galaxy, giving them a better sense of how likely they are to be incorporated into newly forming planets.

NASA's PUNCH mission (Polarimeter to Unify the Corona and Heliosphere). Led by Southwest Research Institute’s office in Boulder, Colorado, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, PUNCH is a constellation of four small satellites heading to low Earth orbit that will make global, 3D observations of the Sun’s corona to learn how the mass and energy there become solar wind.

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: 406

Total landings: 362

Total reflights: 336

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.
