SpaceX Six-Times-Flown Falcon 9, Misses Drone Ship Landing

SpaceX has delivered one other 60-strong batch of Starlink web communications satellites into low-Earth orbit, following Monday evening’s profitable launch of a seasoned Falcon 9 booster from Space Launch Complex (SLC)-40 at Cape Canaveral Space Force Station, Fla. Liftoff of the B1059 core—which became only the third Falcon 9 first stage to record a sixth mission—occurred on time at 10:59 p.m. EST, throughout an “instantaneous” window.

And though first-stage flight proceeded with out obvious incident, as did the second-stage ascent and deployment of its payload, B1059 failed to attain a touchdown on the deck of the Autonomous Spaceport Drone Ship (ASDS), “Of Course I Nonetheless Love You”.

It stays to be seen how this anomaly will impression the next scheduled Falcon 9 launch, which at the time of writing remains targeted for 12:55 a.m. EST Wednesday morning.

It was a tragic finish for a booster which has flown no fewer than six times in a little over 14 months and, in so doing, closes its profession because the third-most-flown member of SpaceX’s fleet thus far. B1059 first entered energetic operational service to ship a pair of Dragon cargo missions to the Worldwide House Station () on 5 December 2019 and once more on 6 March 2020.

These two flights marked the ultimate pair of station-bound flights underneath the phrases of the first-phase Commercial Resupply Services (CRS1) contract with NASA, initially signed method again in December 2008. Between them, they delivered over 11,600 kilos (5,200 kg) of pressurized and unpressurized payloads, tools and provides to the station’s incumbent Expedition 61 and 62 crews.

These payloads included experiments in combustion science, muscle loss, barley malting and foam-pellet manufacturing for Adidas efficiency midsoles.

Additionally they featured Japan’s Hyperspectral Imager Suite (HISUI) for emplacement onto the Uncovered Facility (EF) of the Kibo lab and Europe’s payloads-anchoring platform, whose installation onto the hull of the Columbus lab was effected by spacewalking astronauts last month.

Each of those launches have been preceded by Static Fireplace Exams, but B1059’s third launch on 13 June 2020 represented the primary Falcon 9 to fly with out having been put via this pre-flight ritual, seen as an indicator of the system’s rising maturity.

This mission additionally boasted previously-flown payload fairing “halves” and carried 58 Starlink web communications satellites and three SkySat Earth-imaging satellites, offered by San Francisco, Calif.-headquartered Planet Labs, Inc. The launch was notable in that the 45th Climate crew overseeing the flight was an all-female affair for the first time.

A fourth flight on 30 August—SpaceX’s 100th—was initially supposed to form part of a record-setting “double-header” weekend, with two missions set to fly solely 9 hours aside. However though B1059 efficiently roared aloft with Argentina’s SAOCOM-1B radar-imaging satellite and a pair of “rideshare” payloads, the opposite mission was postponed resulting from a steadily worsening climate outlook.

Nonetheless, B1059’s fourth foray marked the primary polar-orbiting mission from the House since February 1969, in addition to the primary time {that a} Static Fireplace had not been carried out previous to the launch of a serious industrial buyer. And with the opposite mission launching efficiently solely 3.5 days later, B1059 additionally performed its half in securing a record for the shortest interval between any two Falcon 9 flights.

Extra not too long ago, last 19 December, B1059 turned solely the fourth Falcon 9 booster to log a fifth launch when she delivered the extremely secretive NROL-108 payload to orbit on behalf of the Nationwide Reconnaissance Workplace. Though this marked the fourth nationwide safety payload to be by SpaceX, it was the primary time in historical past that it had been tried a previously-flown Falcon 9 core.

With 5 missions thus underneath her belt, the blackened and scorched B1059 core and a sparkling-new second stage have been rolled out to SLC-40 final Friday and—for the primary time since final March—have been put via a Static Fireplace Check.

Launch was initially focused for late Sunday evening, however resulting from unfavorable restoration climate, SpaceX elected to postpone till 10:59 p.m. EST Monday, the place circumstances have been anticipated to enhance from simply 40-percent-favorable to a extra palatable 60-percent-favorable, following the stall of a frontal boundary over North Florida which saved the Cape moist, stormy and unseasonably heat.

By late Monday, nevertheless, a low-pressure space within the Gulf of Mexico was projected to drag the boundary to the north of the Spaceport and impact a brightened outlook. And exactly on time at 10:59 p.m. EST, B1059 took flight, its 9 Merlin 1D+ first-stage engines punching out 1.5 million kilos (680,000 kg) of thrust to get the sixth Falcon 9 mission of 2021 airborne.

First-stage flight appeared to proceed nominally and, after separation, B1059 commenced its descent “burns” because it took goal on the ASDS, “Of Course I Nonetheless Love You”, located some 390 miles (630 km) offshore within the Atlantic Ocean.

However touchdown didn’t come. “Appears like booster missed right now,” famous AmericaSpace’s Launch Tracker at 11:12 p.m. “Because the T+8:40-minute mark handed, a glow confirmed on the display disturbed the seagulls on the ASDS, however didn’t land on the ship.”

It was the primary time that SpaceX had did not land a booster within the final 24 makes an attempt. Final spring, two Falcon 9s missed the drone ship, due to the provision of incorrect wind-speed data and residual cleaning fluid trapped in a sensor. And the lack of B1059 carries explicit resonance, because it has set various touchdown milestones on its earlier flights.

On its first mission in December 2019 it achieved SpaceX’s 20th profitable ASDS landing and on its fourth flight in August 2020 it made the 20th profitable solid-ground touchdown. And in March 2020 it recorded the 50th total touchdown of a Falcon-class automobile—inclusive of drone-ship or solid-ground touchdowns—and final December it logged the 70th time {that a} SpaceX hen had been efficiently recovered intact.
