SpaceX fires up Falcon 9 rockets hours apart for back to back launches

Published

on

SpaceX has fired up two separate Falcon 9 rockets at two separate Florida launch pads in less than 16 hours ahead of back to back launches for Starlink and the US military.

Around 6:30 pm local on June 24th, SpaceX successfully static fired Falcon 9 B1051 as one of the last steps before the booster’s fifth launch, making it the third SpaceX rocket to reach that five-flight milestone in just three months. B1051.4 just narrowly missed SpaceX’s booster turnaround record, falling just a few days short of the current 62-day record after some minor delays. Originally scheduled to launch as early as June 22nd, the ninth batch of Starlink v1.0 satellites (Starlink V1 L9 or Starlink-9) is now scheduled to launch no earlier than (NET) 4:18 pm EDT (20:18 UTC) on Friday, June 26th.

A little over fifteen hours after B1051’s – apparently – successful static fire (there was no SpaceX tweet confirmation for the first time ever) at Kennedy Space Center Launch Complex 39A (Pad 39A), new Falcon 9 booster B1060 performed its own ignition test at SpaceX’s separate Cape Canaveral Air Force Station (CCAFS) LC-40 pad. SpaceX confirmed that that static fire was successful, putting the new Falcon 9 rocket on track to launch the US military’s third upgraded GPS satellite (GPS III SV03) no earlier than (NET) 3:56 pm EDT (19:56 UTC) on Tuesday, June 30th.

If SpaceX manages to complete both the Starlink-9 and GPS III SV03 missions on schedule, June 2020 will be the company’s first four-launch month ever. Even if the latter US military mission is delayed to July 3rd or 4th, SpaceX will still have technically completed four launches in a month’s worth of days (30-31). Normally, the odds of the second in a pair of back-to-back launches being delayed would be quite high, given that any delay to the first mission would inherently roll over onto the follow-up. For SpaceX, that likelihood is more than doubled because of the need for drone ship availability for booster recovery.

However, SpaceX debuted a second East Coast drone ship – Just Read The Instructions (JRTI) on June 3rd, complimenting drone ship Of Course I Still Love You (OCISLY) to double the company’s sea recovery capacity on the East Coast. Formerly stationed at Port of Los Angeles to support SpaceX launches out of California, the West Coast manifest rapidly dried up and made drone ship JRTI’s move East all but inevitable.

On top of having a second drone ship available for booster recoveries just days or even hours apart, SpaceX also recently began pushing the limits of its East Coast launch capacity by performing launches just days apart from its two separate Florida pads. While the occasional back-to-back launch from LC-40 and Pad 39A isn’t unprecedented, SpaceX appears to be intent on sustaining launches from each pad every 10-20 days, give or take. As such, SpaceX’s Starlink-9 and GPS III SV03 missions will launch from separate pads and land on separate drone ships.

Cadence ambitions aside, Starlink-9 and GPS III SV03 are also significant missions for their own reasons. Up first, Starlink-9 will hopefully follow on the heels of SpaceX’s successful June 13th Starlink-8 launch to become the second Starlink rideshare mission, sending two BlackSky imaging satellites into orbit along with 57 Starlink v1.0 satellites. The fact that booster B1051 has nearly broken SpaceX’s rocket reuse turnaround record also suggests that the company is already confident in the flightworthiness of Falcon 9 boosters heading into their fifth launches.

Meanwhile, GPS III SV03 is special because – unlike SpaceX’s first GPS III SV01 launch in December 2018 – the US Air (Space) Force will allow Falcon 9 booster B1060 to attempt a drone ship landing. On SpaceX’s first GPS III launch, the USAF more or less arbitrarily limited Falcon 9’s available performance to leave extreme safety margins in the apparent event of one or more booster engines failing during launch. As a result, Falcon 9 B1054 became the first highly-reusable Block 5 booster to intentionally launch just once. For B1060, the booster will thankfully have a shot at recovery and a long and productive life of 5-10+ more launches. A successful landing could also give the US military its first shot at certifying and reusing a Falcon 9 booster on an operational military satellite launch.

SpaceX aces Starship test flight 10 with successful payload deployment

The mission began at 6:30 p.m. local time in Starbase, Texas, when the launch of Starship initiated. After about eight minutes, stage separation was completed, and the Super Heavy Booster headed back down to Earth for a planned splashdown in the Indian Ocean:

SpaceX aced its tenth Starship test flight on Tuesday night after multiple delays pushed the mission back to this evening. Originally scheduled for Sunday night, SpaceX had two delays push the flight back to Tuesday, which ultimately provided ideal conditions for a launch attempt.

The tenth test flight of Starship had several objectives, including a successful splashdown of the booster in the Gulf of America, the deployment of eight Starlink simulation modules from the PEZ dispenser, and a splashdown of the ship in the Indian Ocean.

SpaceX Starship Flight 10: What to expect

SpaceX successfully achieved all three of these objectives, making it one of the most successful test flights in the Starship program. There was no attempt to catch the booster this evening, as the company had been transparent about it ahead of the launch.

The mission began at 6:30 p.m. local time in Starbase, Texas, when the launch of Starship initiated. After about eight minutes, stage separation was completed, and the Super Heavy Booster headed back down to Earth for a planned splashdown in the Indian Ocean:

Starship was then the main focus of the rest of the broadcast as it completed its ascent burn and coasted through space, providing viewers with spectacular views as the mission headed toward new territory, including the deployment of Starlink simulators. This would be the first time SpaceX would attempt a payload deployment.

The deployment works like a PEZ dispenser, as the simulators were stacked on top of one another and would exit through a small slit one at a time.

This occurred roughly 20 minutes into the mission:

An hour and six minutes into the flight, Starship reached its final destination, which was the Indian Ocean. A successful splashdown would bring closure to Starship’s tenth test flight, marking the fifth time a test flight in the program’s history did not end with vehicle loss.

It was also the first of four test flights this year that will end with Starship being recovered.

SpaceX is expected to launch Starship again in approximately eight weeks, pending the collection of data and other key metrics from this flight.

Tesla one-ups Waymo once again with latest Robotaxi expansion in Austin

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

Tesla’s expansion of the Robotaxi geofence on Tuesday morning was a one-up on Waymo once again, as the automaker’s service area growth helps eclipse its rival in an intense back-and-forth.

A lot of conversation has been made about Tesla’s rivalry with Waymo in terms of the capabilities of its driverless ride-sharing service in Austin, Texas.

The two companies have sparred with one another, answering each other’s expansion, and continuing to compete, all to the benefit of consumers in the region.

Tesla expanded the geofence of Robotaxi once again this morning, and it is another growth that catapults it past Waymo’s service area in Austin — this time by a considerable margin.

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

On July 14, Tesla officially overtook Waymo in terms of service area in Austin. But just a few days later, Waymo had responded with a bold statement, expanding from 37 square miles to 90 square miles.

Sarfraz Maredia, Global Head of Autonomous Mobility & Delivery at Uber, said the move “unlock[ed] another key milestone in Austin as our operating territory with Waymo expands from 37 to 90 square miles, which means that even more riders can experience Waymo’s fully autonomous vehicles through the Uber app.”

Tesla did not respond immediately, but it took its time with validation vehicle testing in the Austin suburbs, as we reported yesterday:

Tesla looks to expand Robotaxi geofence once again with testing in new area

Today’s expansion is perhaps the biggest step Tesla has taken in its efforts to continue to grow its Robotaxi platform. This is not only because the company has significantly expanded the size of the geofence, but also because it has ventured into suburban areas and even included Gigafactory Texas in its service area.

Waymo could come up with another timely response as it did when Tesla expanded in late July. We’ll wait to see what it comes up with, as this awesome competition between the two companies is accelerating innovation.
