Falcon za Falconem 03.02. o 18:13:20 z KSC wystrzelona została RN Falcon-9R. Wyniosła ona w T+8' 50" na orbitę o parametrach: hp=190 km, ha=380 km, i=53,2° 49 satelitów Starlink Group 4-7. Pierwszy stopień RN (B1061.6) w T+8' 26" wylądował na barce ASDS ASOG na Atlantyku.
EDIT:
W związku z gwałtowną burzą geomagnetyczną, która miała miejsce nazajutrz po starcie, wydano im komendę przejścia w safe-mode i ustawienia się swą płaszczyzną równolegle do kierunku lotu, w celu zminimalizowania efektu tarcia o atmosferę, której gęstość wzrosła na wysokości perigeum o 50%. Jednak zanim burza minęła, znaczna ilość (około 40 sztuk) satelitów nie zdołała wyjść z safe-mode celem podniesienia orbity i spłonęła w atmosferze, bądź spłonie w najbliższym czasie.
Jednocześnie pojawiła się informacja, że po lądowaniu pierwszego stopnia nie został on zamocowany i znacznie przesunął się po pokładzie barki.http://lk.astronautilus.pl/n220201.htm#02SpaceX Starlink 36 launch & Falcon 9 first stage landing, 3 February 2022Trzy Falcony 9 w trzy dni BY KRZYSZTOF KANAWKA ON 4 LUTEGO 2022

The Starlink 4-7 mission was delayed from last weekend to wait for two higher-priority Falcon 9 launches. One of those, carrying an Italian radar satellite, suffered a series of delays caused by bad weather and a cruise ship in the downrange launch hazard area. (...)
SpaceX has launched 2,042 Starlink satellites to date, including spacecraft that have failed or already been decommissioned, and the 49 satellites that took off Thursday brought that number to 2,091. (...)
SpaceX this week also unveiled a new “premium” offering of its Starlink internet service targeted at business and enterprise customers. Starlink Premium, SpaceX says, is “designed specifically for high demand users.”
As of last month, SpaceX said the Starlink network was live in 25 countries and regions, serving more than 145,000 users worldwide. SpaceX builds its Starlink satellites on an assembly line in Redmond, Washington, and the company is developing and iterating its own user terminals.
For the standard Starlink service, customers pay $499 for a Starlink antenna and modem, plus a $99 refundable deposit. A subscription for the high-speed, low-latency service runs $99 per month.
To sign for SpaceX’s Starlink Premium product, a customer must pay a $500 refundable deposit and $2,500 for delivery of ground equipment to connect to the network. The monthly rate for service is $500.
Starlink Premium offers double the antenna capability of the standard Starlink service, along with a signal that’s designed to perform better in extreme weather, according to SpaceX. Deliveries for Starlink Premium customers will begin in the second quarter of this year. (...)

B1061—which flew most recently in December to lift NASA’s Imaging X-ray Polarimetry Explorer (IXPE)—rose from Earth at 1:13 p.m. EST and returned eight minutes later to a smooth touchdown on the deck of SpaceX’s newest Autonomous Spaceport Drone Ship (ASDS), “A Shortfall of Gravitas”. (...)
For a time, it seemed possible that SpaceX would attempt two missions within two hours of each other, as B1061 flew Starlink from the Cape and the brand-new B1071 core rose from Vandenberg Space Force Base, Calif., laden with the highly secretive NROL-87 payload for the National Reconnaissance Office. Targeted launch times (though unconfirmed by SpaceX) saw NROL-87 flying at 12:18 p.m. PST, followed by Starlink at 4:51 p.m. EST, a mere 93 minutes later. That would have set a new personal best for the shortest interval between a pair of SpaceX launches, eclipsing the 15 hours set between two missions last December. (...)

Solar storm dooms up to 40 new Starlink satellitesFebruary 8, 2022 Stephen Clark
SpaceX says the effects of a solar storm will destroy as many as 40 of 49 new Starlink internet satellites launched from Florida last week.
Some of the satellites have already re-entered the atmosphere, and more are expected to plunge back to Earth in the coming days. The satellites are designed to burn up when they fall to Earth. (...)
