Jacques Van Oene's photos of the Static Fire for Falcon 9 B1046.2. Takes around 30 minutes or so for SpaceX to review the test, via a "quick look" review. Then they head into the LRR (Launch Readiness Review) about a day prior to launch.

Static fire test of Falcon 9 complete—targeting August 7 launch of Merah Putih from Pad 40 in Florida.

SpaceX spotted hot-fire testing Falcon 9 Block 5 ahead of its first reflight on August 7

Posted on August 2, 2018

Less than three months after SpaceX debuted its upgraded Falcon 9 Block 5 rocket, the company is set for an unexpectedly sudden inaugural reuse of the first highly reliable and reusable rocket to roll off of the Hawthorne, CA assembly line.

Falcon 9 booster 1046 (B1046) is now targeting 1:18 AM EDT, August 7 for its second launch.

Confirmed by visual observation of a sooty Block 5 booster vertical on Cape Canaveral's Pad 40, this reuse will be just two weeks away fr om beating SpaceX's booster turnaround record of 72 days.

Static fire test of Falcon 9 complete—targeting August 7 launch of Merah Putih from Pad 40 in Florida.

8:53 PM - Aug 2, 2018

On the ground to visually confirm plans for the historic reuse, Teslarati photographer Tom Cross also managed to capture an intriguing propellant loading and abort test, wh ere SpaceX appeared to intentionally abort a 'launch' attempt after rapidly loading a full complement of liquid oxygen (LOX) and rocket-grade kerosene (RP-1).

While not 100% clear why this testing was done today, an extensive understanding of Falcon 9 Block 5's behavior during propellant late-load and launch abort scenarios are both critical for the reliable operation of the upgraded rockets and invaluable for the first Crew Dragon launches later this year and early next, the latter with astronauts on board. With humans atop the rocket, a deep understanding of the vehicle's behavior during a wide range of off-nominal scenarios is more critical than ever, be it required by NASA or simply a side effect of due diligence on behalf of SpaceX.

A NEW ERA OF REUSABLE ROCKETS

Regardless, the main focus of this mission is to launch a payload for Indonesian operator PT Telkom Indonesia, in this case a ~5800 kg (12800 lb) geostationary communications satellite known as Merah Putih (formerly Telkom 4). On the SpaceX side of things, this mission is absolutely critical for the company's future – it will mark the (hopefully) successful inaugural reuse of a Falcon 9 Block 5 booster, the first of many dozens or even hundreds to come over the next several years if SpaceX's can make good on its aspirations.

While not immensely impressive in the sense that B1046's refurbishment took ~85 days to Block 4's record 72-day turnaround, that cursory conclusion is far from accurate. The record turnaround with Block 4 booster B1045 was essentially the culmination of more than a year of experience with nearly a dozen Block 3 and Block 4 Falcon 9 reuses. While that experience definitely transferred in part to SpaceX's first attempt at reusing Falcon 9 Block 5 (and especially so with the actual design of its reusability-focused upgrades), it's worth noting that the first reuses of Falcon 9s averaged booster turnaround times of 180-250 days, nearly double or triple the time between Block 5's first-ever launch and that same booster's first reflight.

Even still, B1046's debut launch, landing, and refurbishment were wholly unique considering that SpaceX – according to Elon Musk – conducted an extensive "teardown" analysis of the pathfinder rocket after it was transported from the drone ship back to one of the company's Cape Canaveral refurbishment facilities. It's very likely the case that that teardown was one of the most extensive SpaceX has done with a recovered rocket, couched on the fact that the company's future is wholly balanced on Falcon 9 Block 5's success and ease/efficiency of reusability.

That critical teardown process likely took anywhere from 30-60 days, if not simply as long as needed to do it right, after which the rocket was fully reassembled and transported to SpaceX's Launch Complex 40 (LC-40). Roughly eight days after it arrived at LC-40, B1046 rolled out to the pad's launch mount, went vertical, and completed a series of tests (including static fire) on Thursday (8/2) afternoon. The static fire was confirmed by a few observers, while Tom Cross captured the first unequivocal proof that the rocket is sooty (and thus B1046).

This moment may seem small on the scale of SpaceX's many towering achievements, but it will very likely become a fundamental keystone in the future history of affordable access to space.

SpaceX conducts hotfire test for another middle-of-the-night launch
August 2, 2018 | Stephen Clark

Gearing up for the third Falcon 9 launch in less than two-and-a-half weeks, SpaceX fired up a rocket booster at Cape Canaveral on Thursday ahead of an early morning launch Tuesday with an Indonesian communications satellite.

Nine first stage engines on the Falcon 9 rocket ignited around 12:45 p.m. EDT (1645 GMT) Thursday at Cape Canaveral's Complex 40 launch pad, firing for several seconds before a shutdown command. SpaceX confirmed the static fire test in a tweet later Thursday afternoon.

The static fire test is a routine step in SpaceX's launch campaigns, during which the company's launch team oversees the loading of kerosene and liquid oxygen propellants into the Falcon 9 rocket before a brief hold-down engine firing. The test serves as a checkout of the launch vehicle and ground systems, and an exercise for the SpaceX launch team.

Ground crews will lower the Falcon 9 rocket and return it to a nearby hangar for attachment of the Merah Putih spacecraft this weekend. The launcher will roll back to the pad in advance of a two-hour launch window opening at 1:18 a.m. EDT (0518 GMT) Tuesday.

If the flight takes off on time, SpaceX's next launch will mark the third Falcon 9 flight in 16 days, one of the busiest periods of launch activity in the company's history. It will be the 15th launch by SpaceX so far this year.

Photos of the Falcon 9 launcher at Complex 40 taken Thursday showed soot markings suggesting the first stage was flown on a previous mission, likely in May on the launch of the Bangabandhu 1 communications satellite. That mission marked the inaugural flight of SpaceX's upgraded Falcon 9 Block 5 vehicle, sporting improvements to make the first stage easier to recover and reuse.

A SpaceX spokesperson did not respond to an inquiry about the identity of the Falcon 9 first stage set to fly with the Merah Putih satellite.

The Merah Putih satellite, formerly known as Telkom 4, will provide C-band telecommunications services over Indonesia and India. The new telecom craft was built by SSL in Palo Alto, California.

Officials renamed the satellite Merah Putih to represent the red and white of the Indonesian flag, according to SSL.

SSL completed construction of the Merah Putih satellite ahead of schedule, according to Telkom Indonesia, also known as PT Telkom. The new satellite will replace Telkom 1, which failed in a mysterious debris-shedding event in geostationary orbit last year.

Officials from Telkom Indonesia expected the Telkom 1 satellite, which launched in 1999, to remain operational until Merah Putih's launch. But Telkom 1's failure last year forced the operator to re-route communications traffic through other satellites.

The Merah Putih satellite is designed for a 16-year life, its owner said in a statement. The spacecraft will be positioned in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator at 108 degrees east longitude.

"Satellite plays a vital role in our telecommunications infrastructure," said Zulhelfi Abidin, chief technology officer of Telkom Indonesia, in a press release earlier this year. "SSL has been an excellent spacecraft supplier and has completed the satellite construction ahead of schedule. We look forward to traveling to Florida to see the satellite launch later this summer."

Merah Putih carries 60 C-band transponders with coverage across the Indonesian archipelago, and other parts of South and Southeast Asia. The satellite will provide Internet, telephone and cellular backhaul services, according to SSL.

The launch will also keep intact a summertime streak of middle-of-the-night and early morning launches from Cape Canaveral. The last three Falcon 9 missions from Florida's Space Coast since early June have launched in the wee hours, and two more liftoffs are scheduled to occur in the middle of the night or predawn hours later this month.
