#Falcon9 still stands tall 2 days after spectacular sonic boom announced touchdown Landing Zone-1 ca 9min after historic #SpaceX #SAOCOM1B polar orbit launch Aug30 to south. And same day the 2 payload fairing halves arrived back @PortCanaveral.Landing legs still deployed it seems
Always love a rocket launch during that golden hour before sunset or even that twilight/blue hour right after! Here’s one of those moments from the recent #SpaceX #SAOCOM1B launch.
Here is the telemetry from the SAOCOM-1B mission. Some points of interest are:1. A small amount of the dogleg manoeuvre was accomplished by the first stage, as you can see from the attached still of MECO from the Mission Control Audio video.2. On the mission video you can see the second stage yaw manoeuvre stop at the T+03:30 (210s) mark, and this coincides with the increase in acceleration at 210s in the plot.3. The mission profile used direct injection to a nearly circular orbit of 620 x 603km. I had mistakenly assumed the payload would be too heavy for direct injection, and assumed MECO would occur about 70km downrange. MECO was actually much closer to 40km downrange, and so I've attached my predicted and corrected ground tracks below.4. The second stage throttled back quite substantially from the 360s mark until SECO.5. There is a data glitch at 560s that can safely be ignored.
That updated ground track is not correct. It should not run outside the keepout zones like that. There should be a parallel line to somewhere on the ground track that runs straight through the centerline of the back side keepout zones. For the grey zones in the second image that is not the case.
Streak shot from the SAOCOM 1B launch & landing earlier this week. The clouds made for a dramatic pre-sunset show, but also made it harder to appreciate the new Cape-polar trajectory from the ground.

Quote from: FutureSpaceTourist on 09/09/2020 02:56 pm[youtube link above]Worth noting here that THIS HAS AUDIO. I don't recall that being provided before.I hope someone slows it back down to real time.
I think it's MECO around 0:14 and then boostback burn startup around 0:18.

Pursuant to 47 C.F.R. § 5.54(a)(1), EchoStar Global Australia Pty Ltd(“EchoStar Global”), a wholly owned subsidiary of EchoStar Corporation, requests a two-yearconventional experimental license to operate a gateway earth station in Germantown, MD, forfeeder link communications with its Australian-licensed non-geostationary orbit (“NGSO”)mobile satellite service (“MSS”) system (“EG System” or “System”). Grant of this applicationwill serve the public interest by facilitating testing and development of new MSS equipment andtechnology that ultimately will be deployed to support mobile communications, public safety,and other services worldwide. Background. With its parent company’s extensive experience in the satellite industry,EchoStar Global is in the process of designing, constructing, and launching a new NGSO MSSsystem to provide narrowband data services, including machine-to-machine and Internet ofthings communications, throughout the globe. Pursuant to Australian authorization andInternational Telecommunication Union (“ITU”) filings for the SIRION-1 network, the EGSystem is licensed to provide MSS on S-band frequencies at 2000-2020 MHz (uplink) and 2180-2200 MHz (downlink). The System will consist of a constellation of approximately 28 satellitesin low Earth orbit, including EG-1, which was successfully launched in August 2020, and EG-3,scheduled for launch June 2021. Additionally, EchoStar Global has acquired ownership ofPathfinder II, launched in December 2018, for operations under the SIRION-1 ITU filings.
