The upper stage first deployed a small satellite named Tyvak 0130 built by Tyvak Nano-Satellite Systems, a small spacecraft manufacturer in Irvine, California. SpaceX did not disclose details about the Tyvak 0130 spacecraft, and Tyvak has not listed the mission on its website.
A regulatory document posted on a NOAA website says the federal agency, which oversees licensing of U.S. remote sensing satellites, granted approval to Tyvak in 2019 to “operate a private, space-based, remote sensing system named Tyvak 0130.”
The document describes Tyvak 0130 as an “optical spectrum astronomy observation satellite,” but offered no further details. The age of the document could also mean the description might be dated.
Capella Space’s fourth commercial radar imaging satellite also hitched a ride on Saturday’s mission. The spacecraft, with a launch weight of roughly 220 pounds (100 kilograms), will join three other operational Capella radar remote sensing satellites.
The new Capella radar satellite separated from the top end of the stack of Starlink satellites about one hour into the Saturday’s mission.
Based in San Francisco, Capella is one of several companies developing fleets of radar imaging satellites. After launch, Capella’s spacecraft will unfurl its radar reflector antenna to a diameter of about 11.5 feet (3.5 meters) and begin collecting imagery. (...)
The launch Saturday was the 28th Falcon 9 flight with a primary goal of deploying Starlink satellites. It was the fourth Starlink flight to carry rideshare payloads from other customers. (...)

With the completion of Saturday evening’s mission, those 15 launches have been accomplished by six boosters, a remarkable footnote for SpaceX’s reusability credentials.
Including today’s flight, those launches have put 722 Starlinks into orbit, plus Turkey’s powerful Türksat-5A geostationary communications satellite and Crew-2 astronauts Shane Kimbrough, Megan McArthur, Aki Hoshide and Thomas Pesquet aboard Dragon Endeavour.
Additionally, Transporter-1, which rode B1058 to orbit in January, marked the largest single haul of primary payloads—143—ever lifted by a U.S. vehicle. And despite still being less than half-done, 2021 has seen the first Falcon 9 to fly a tenth time and the shortest interval of only 27 days between a pair of launches by the same booster.
Having first launched last 30 May to ferry Dragon Endeavour on her historic voyage to the space station, B1058 flew a second mission on 20 July to deliver South Korea’s ANASIS-II military communications satellite into orbit. This marked the shortest interval, only 51 days, between any two launches of a reusable orbital-class vehicle from the Space Coast, eclipsing the 54 days set by shuttle Atlantis between her first two missions in the fall of 1985. (...)
It was the 14th on-point droneship landing of the year, out of 15 attempts. And although SpaceX has routinely completed as many as three Falcon 9 flights in the span of a single calendar month, to have done so three times in the first half of a month proved unprecedented. (...)

The small satellite, named Tyvak 0130 and weighing about 25 pounds (11 kilograms), launched Saturday from NASA’s Kennedy Space Center in Florida with a cluster of 52 Starlink internet satellites and a radar observation craft from Capella Space.
A spokesperson for Tyvak Nano-Satellite Systems, based in Irvine, California, said Monday that the small Tyvak 0130 satellite carries optical telescopes capable of black-and-white and color imaging. The telescopes were developed in collaboration with Lawrence Livermore National Laboratory, according to Tyvak.
The Tyvak 0130 satellite is based on a 6U CubeSat platform. The main body of a 6U CubeSats is typically about the size of a briefcase.
Tyvak said the new satellite builds on lessons learned from Tyvak 61, a smaller 3U CubeSat launched in 2018. Tyvak 61, also known as GeoStare, tested the performance of monolithic telescope design that could be used to collect remote sensing data for Earth observation, astronomy, and space debris tracking applications.
The monolithic telescope replaces the primary and secondary mirror structures in standard telescopes with one solid piece of glass, according to Tyvak and LLNL, with optical shapes and reflective coatings at both ends of the glass. (...)
