Z Canaveral na południe 30.08. o 23:18:56,462 z Cape Canaveral wystartowała RN Falcon-9R. Wyniosła ona na orbitę o parametrach: hp=603 km, ha=620 km, i=97,87° satelitę SAOCOM-1B oraz w ramach misji Smallsat Rideshare Mission 1 (SSO) dodatkowo GNOMES-1 i Tyvak 0172. Był to pierwszy od 1969 roku start z Cape Canaveral na orbitę polarną. Pierwszy stopień RN (B1059.4) wylądował na LZ-1.

Start rakiety Falcon 9 - 31 sierpnia 2020 / Credits - SpaceXW poniedziałek 31 sierpnia doszło do dwóch startów rakiet: Electrona z Nowej Zelandii oraz Falcona 9 z Florydy.
Z Florydy na orbitę polarną(...) Cechą szczególną tego startu była trajektoria lotu rakiety Falcon 9. Był to pierwszy start z Florydy od 1960 roku, w której wyniesiono satelity na orbitę polarną. Lot rakiety Falcon 9 przebiegał wzdłuż wybrzeża Florydy. Tę możliwość startów wprowadzono na początku 2018 roku.

Instead of launching toward the northeast or east, the Falcon 9 darted through a cloudy sky and arced to the south-southeast from Florida’s Space Coast, then made a right turn to fly along the east coast of Florida over Fort Lauderdale and Miami on the way to a polar orbit.
The launch Sunday was the first from Cape Canaveral to fly on a southerly track since 1969. Since then, most U.S. launches into polar orbit have departed from Vandenberg Air Force Base in California, which has an open range over the Pacific Ocean that does not require rockets to make an in-flight turn, or “dogleg” maneuver, to avoid flying over land. (...)
It was the 18th time SpaceX has landed a Falcon 9 booster at Cape Canaveral since 2015, and the 59th successful recovery of a Falcon 9 first stage overall, including landings on SpaceX’s ocean-going drone ships. (...)
The Argentine-built satellite, equipped with a sophisticated radar imaging instrument, separated from the Falcon 9’s upper stage about 14 minutes into the mission. Two smaller rideshare payloads — named GNOMES 1 and Tyvak 0172 — deployed from the Falcon 9 about 45 minutes later.
The GNOMES 1 microsatellite is the first of a planned fleet of around 20 small spacecraft being developed by a Colorado-based company PlanetiQ to collect radio occultation data by measuring the effects of the atmosphere on signals broadcast by GPS, Glonass, Galileo and Beidou navigation satellites. The information can yield data on atmospheric conditions that are useful in weather forecasts.
Tyvak 0172 is a small spacecraft built by Tyvak Nano-Satellite Systems. Details about its mission have not been disclosed by SpaceX or Tyvak.
SpaceX launches first polar orbit mission from Cape Canaveral since 1969The rideshare payload separations wrapped up the first launch into polar orbit from Florida’s Space Coast in more than 50 years.
Before Sunday, the last polar orbit launch from Cape Canaveral was on Feb. 26, 1969, when a Delta rocket launched the ESSA 9 weather satellite.
After skirting South Florida, the Falcon 9 rocket flew over Cuba and Central America, then soared over the Pacific Ocean west of South America. The bend in the rocket’s track a few minutes after launch ensured the instantaneous impact point — where debris might fall of the launcher failed — did not cross over Florida after departing Cape Canaveral.
By the time the rocket reached Cuba, it was flying too high to be a safety concern, according to officials from the U.S. Space Force’s 45th Space Wing and the Federal Aviation Administration, which are charged with ensuring public safety during rocket launches from Cape Canaveral.
This approximation of the SAOCOM 1B flight path is an estimate derived from downrange hazard areas and the satellite’s known target orbital parameters. Credit: Spaceflight NowRange safety officials studied whether the the southerly launch trajectory from Florida might be resurrected after wildfires at Vandenberg Air Force Base — the primary U.S. polar orbit launch site in California — threatened launch and payload processing facilities in 2016.
It turned out SpaceX’s ability to return first stage boosters to controlled landings — rather than having them plummet unguided back to Earth downrange — and the Falcon 9’s use of autonomous flight safety system made the polar launch trajectory from Cape Canaveral feasible. (...)
A satellite launching from Cape Canaveral targeting a polar orbit in 1960 suffered an in-flight failure and spread debris over Cuba, reportedly killing a cow and prompting protests at the U.S. Embassy in Havana. (...)

Polar orbits are popular for weather and remote sensing satellites to enable coverage of the Earth’s full surface. SpaceX launched the first Saocom satellite, Saocom-1A, into a polar orbit from Vandenberg in October 2018 on a Falcon 9.
The Aug. 30 launch of Saocom-1B completes Argentina’s Saocom system, comprised of twin 3,000-kilogram satellites equipped with L-band phased array antennas that can image day and night and through clouds.
The Saocom satellites are designed to detect soil moisture and strengthen Argentina’s agricultural sector. (...)

And within eight minutes of leaving the ground, B1059 achieved SpaceX’s 20th landing of a rocket stage on solid ground in less than five years when it alighted on Landing Zone (LZ)-1 at the Cape. (...)
In readiness for this impressive challenge, B1059 was transported out to SLC-40 and SpaceX confirmed it was vertical early Sunday. Interestingly, at the time of writing, neither of the two cores was put through a customary Static Fire Test of their nine Merlin 1D+ first-stage engines. That in itself has occurred before, on B1059’s most recent launch in June, but when it also occurred prior to SAOCOM-1B it marked the first time that no Static Fire Test has been performed ahead of the launch of a major commercial customer. (...)
Fourteen minutes after launch, Argentina’s 3,500-pound (1,600 kg) SAOCOM-1B—one of the largest satellites ever built in the Southern Hemisphere—was successfully deployed to begin its mission. Equipped with powerful L-band Synthetic Aperture Radar (SAR), it is tasked with conducting all-weather observations of Earth as part of ongoing efforts to mitigate the effects of natural disasters.
