SpaceX's next Falcon Heavy launch may see a record landing in the center



Thanks to a temporary reopening of the US Federal Government, SpaceX has been able to continue the registration process for FCC and FAA, which will be required to acquire approval for upcoming launches, including Falcon Heavy.

Such an application referred to the first The launch of Falcon Heavy has produced a rather impressive statistic: SpaceX pointed out that the center core of Falcon Heavy consists of three first booster boosters on the drone ship Of II Love You (OCISLY) almost 1000 km away will be

The same FCC applications also unveiled a start date of "No Earlier Than" (NET): March 7, 2019. Originally set for mid-to-late February the complexity and goal The logistical challenges of building, sending, testing, and delivering two subboosters, one center-core, one Upgrading and a payload fairing from the California SpaceX plant to the test facilities in Texas and the launch ramp from Florida have unsurprisingly impacted the startup schedule. However, if the start dates are actually 7 March, SpaceX will not have missed the mark, considering that this Falcon Heavy – based on new and more powerful Block 5 Boosters – is likely to be a significant departure from Block 2 / Block 3 -Hardware This has flight experience from launching the triple-booster rocket in February 2018.

Less than a year after Falcon Heavy's debut, it appears that the missile's second and third missile launches are being driven back by a fundamental lack of production capacity. In other words, SpaceX's Hawthorne Rocket Factory simply had to focus on more critical priorities in the 6-9 months following the demo mission. Almost at the same time as Falcon Heavy first launched, SpaceX's world-class production team was in the process of producing the first upgraded Falcon 9 Block 5-Booster (B1046), ending just ten days after Heavey's Feb 6 debut debut , the scout rocket sent to McGregor, Texas, for the first static fire of a block 5 booster.

In the meantime, SpaceX's decision to intentionally reused in another way meant that the fleet flying rockets of the company quickly moved to zero. The step explicitly stated by CEO Elon Musk should create room 5 for block 5, the future (and final) of the Falcon family. SpaceX's strong launch manifest for 2018 and several critical missions for the US government were therefore geared to the success, reliability and rapid production of a range of Merlin engines, boosters and advanced stages. These included B1051 – the first explicitly crew-rated Falcon 9 – and B1054, the first SpaceX rocket to launch high-quality US military (especially the Air Force). However, SpaceX also had to build a squad of Falcon 9 boosters that are easy to reuse to support about a dozen other commercial launchs of the manifesto.

This gambling has finally paid off. Block 5 did a great job supporting a reasonable, if not record-breaking, reuse rate. SpaceX has successfully launched B1054 for the USAF, completed B1051 (now on Pad 39A and awaiting NASA approval), and built enough reusable Block 5 boosters to support nine additional commercial missions in 2018. In retrospect, the assumption of a truly miraculous and unforeseen event precludes Falcon Booster production rates, Falcon Heavy's next product launches were almost guaranteed almost six to twelve months after the launch of the rocket – SpaceX's entire launch business depended on building more than 5 independent Falcons 9 boosters off while customers were from Falcon Heavy, Arabsat and USAF It is unlikely that he was inducted so early into the career of Block 5 with air-proven hardware.

All Cylinders Firing

After Falcon 9 B1054 left SpaceX's Hawthorne plant (see above) in early October, the company's production team seemed to swivel directly toward integration and the next to transport three (or more) Falcon Heavy boosters back and forth for the second and third rocket launches. The first new sub-amplifier left the factory in mid-November, followed by a second sub-amplifier at the beginning of December and a (probably very likely) central core around the turn of the year 2019. Both sub-amplifiers were statically fired in Texas and are now at the SpaceX sites in Florida while the center core has either completed its static fire tests in Texas or is already heading east.

Once the Center Core and the Upper Stage are on SpaceX's Kennedy Space Center Pad 39A, engineers and engineers can integrate the second Falcon Heavy that ever existed in preparation for a critical event static fire test. This could already be the case in February, even though the debut of Crew Dragon (DM-1) – now NET March of Pad 39A after relentless cuts – probably takes precedence over Falcon Heavy and could directly disrupt the start. Because the launch pad and transporter / erector (T / E) must be changed for at least a few days to switch between Falcon 9 and Heavy.

Regardless, the next two launches by Falcon Heavy are worth the wait. SpaceX's FCC records indicate that after launch, the center core may land almost 1000 km east of pad 39A east of pad 39A to land OCISLY, which was the previous record attempt – during the launch of Eutelsat 117WB in June 2016 – from about 700 km (430 mi). The Falcon 9 booster – albeit a less powerful Block 2 variant – was unsuccessful in its landing attempt as it lacked the oxidants seconds before landing. Falcon Heavy's debut center core experienced a completely different, but no less deadly, anomaly during the landing that resulted in the drone ship being driven into the Atlantic at nearly half the speed of sound (480 km / h).

Known For its rocket performance estimates, the NASASpaceflight forum user Orbiter first pointed to the impressive distance estimated by the assignment of coordinates in SpaceX's 28th FCC application, and estimated that the Falcon Heavy Center booster flying with a trajectory could be as fast as ~ 3.5 km / s ( 2.2 mi / s) with main engine shutdown (MECO), the point at which the booster separates from the upper stage and the fairing. This would be an almost unprecedented speed for any Falcon booster, let alone a booster with plans to land after takeoff. The Falcon 9 MECO normally performs at recoverable missions at speeds between 1.5 and 2.5 km / s, while even the last retractable GPS III launch cut F9 S1 engines by 2.7 km / s.

Whether this MECO speed estimate is correct, Falcon Heavy's NET March The launch of the ~ 6000 kg Arabsat 6A satellite is likely to be an exceptionally hot reentry and recovery for the center-core, while the duo-booster duo of the Rocket will try a repeat of the spectacular double landing of the debut mission at LZ-1.
