CAPE CANAVERAL, Fla. — SpaceX successfully launched an developed GPS satellite tv for computer for the U.S. Region Drive on Thursday (Nov. 5), marking the foremost begin in nearly two weeks right here on the Region Flee.
One of many firm’s two-stage Falcon 9 rockets blasted off from Region Inaugurate Advanced 40 at Cape Canaveral Air Drive Standing right here at 6: 24 p.m. EST (2324 GMT), carrying the GPS III-SV04 satellite tv for computer to orbit. 9 minutes later, the rocket’s first stage touched down on the deck of “Of Route I Restful Delight in You,” indubitably one of SpaceX’s two drone ships.
The GPS III-SV04 mission had been quandary to apply on the heels of a United Inaugurate Alliance (ULA) Atlas V rocket, which became as soon as scheduled to loft a U.S. witness satellite tv for computer from Cape Canaveral on Tuesday (Nov. 3). Nonetheless, the Atlas V begin became as soon as delayed twice attributable to factors with floor methods equipment. ULA is now concentrated on Friday (Nov. 6) for that liftoff.

It became as soon as a crystal sure evening right here on the Region Flee, and onlookers were ready to apply the rocket thru the assorted phases of begin. A nebula-adore cloud, in overall visible on sure nights, fashioned across the rocket as the foremost and 2nd levels separated. The booster’s reentry burn became as soon as also visible from a press viewing quandary.
Tonight’s GPS mission had been ready to obtain off the ground since SpaceX became as soon as forced to call an abort on Oct. 2. Within the relaxation seconds of the countdown that day, the Falcon 9’s computer detected an engine anomaly, and the rocket’s onboard flight termination system shut the engines down. Crews were ready to safe the automobile and, after a thorough investigation, pinpoint the topic.
SpaceX clear that residue from a “keeping lacquer,” which is designed to guard gathered engine diagram at some level of anti-corrosion anodizing therapy, became as soon as left within the abet of submit-therapy. The lacquer ended up blocking 0.06-run-wide (1.6 millimeters) vent holes for valves in two of the nine Merlin engines on the Falcon 9’s first stage, SpaceX representatives talked about in a news briefing on Oct. 28.
The same traces of lacquer were detected in engines on two other Falcon 9 first levels — one on the rocket that can begin the Sentinel-6 Earth-commentary satellite tv for computer and one on the booster that can begin Crew-1, SpaceX’s next astronaut mission. SpaceX has swapped out the affected engines. The Crew-1 begin date, scheduled for Nov. 14, became as soon as no longer tormented by this swap. Nonetheless, SpaceX and NASA are suspending the Sentinel-6 mission till after Crew-1, surroundings a brand recent scheme date of Nov. 21.
This day’s flight marks the third GPS transport for SpaceX. Two old developed GPS III missions also launched on Falcon 9 rockets, at the side of one this past June. But one more of the satellites launched on the relaxation flight of ULA’s Delta IV Medium in August 2019.
The U.S. defense force plans to begin an entire of 10 upgraded GPS satellites, which is ready to change growing old contributors of its recent constellation. SpaceX has secured extra contracts to begin the subsequent two GPS III missions, that are expected to buy off one day next Twelve months.
Constructed by Lockheed Martin in Colorado, the GPS III-SV04 satellite tv for computer launched this day is the fourth member of an upgraded technology of GPS navigation spacecraft that beam down increased-energy alerts which would perhaps perhaps presumably be extra resilient to jamming and boast extra broadcast frequencies to obtain the GPS community extra adore minded with other an identical constellations, Lockheed representatives have talked about.

Falcon’s fury
The 227-foot-expansive (70 meters) Falcon 9 is SpaceX’s workhorse, and the rocket boasts larger than 1.5 million kilos of thrust at liftoff. This day’s mission featured a contemporary-off-the-manufacturing facility-floor Falcon, its exterior stark white for its first day bound to house.
SpaceX has been relying carefully on its rapid of extinct rockets, with many Falcon 9 first levels having racked up five or extra flights every. The booster that launched this day, identified by the SpaceX designation B1062, would perhaps perhaps presumably be the relaxation price-recent one we peep begin a GPS satellite tv for computer, as the U.S. executive has given SpaceX the inexperienced light to begin future defense force missions on flight-confirmed boosters.
That call followed on the heels of one other recent announcement to enable SpaceX to obtain better the rocket’s first stage at some level of nationwide security missions — something that became as soon as previously no longer allowed. The next two GPS missions, that are already scheduled to scurry on SpaceX rockets one day next Twelve months, will now begin atop refurbished rockets.
That announcement is a foremost for nationwide-security payloads and would perhaps perhaps presumably result in financial savings of nearly $53 million for American taxpayers across the two flights, Region Drive officers talked about.
What’s in a name?
The defense force has given nicknames to every of the upgraded GPS satellites, naming them after notorious explorers. The satellite tv for computer that launched tonight became as soon as given the moniker “Sacagawea” after the Shoshone manual who helped Lewis and Clark on their expedition thru the American West within the early 1800s.
Outdated satellites were named “Vespucci” and “Magellan” in honor of explorers Amerigo Vespucci and Ferdinand Magellan. The satellite tv for computer that launched in June became as soon as on the foundation dubbed Columbus, nevertheless it no longer too lengthy ago obtained a brand recent nickname: “Henson,” in honor of gloomy explorer Matthew Henson, who became as soon as part of the foremost expedition to the North Pole larger than a century ago.
All of the monikers are unofficial nicknames given to the satellites ahead of begin as a activity of honoring explorers of the past and continuing a spaceflight tradition of naming spacecraft.
The next few missions already have names chosen for the respective satellites. The fifth satellite tv for computer, GPS III-SV05, will be called Neil Armstrong. Region Drive officers divulge other satellites to come abet will be named after Amelia Earhart, Sally Walk and Katherine Johnson.
Flight milestones
This day’s mission marks the 97th Falcon 9 rocket to scurry and the 20th mission of 2020 for SpaceX. It also marks the 64th a success booster recovery. SpaceX’s drone ship, “Of Route I Restful Delight in You,” became as soon as positioned out within the Atlantic Ocean, expecting its recovery strive.
The firm’s other drone ship, “Appropriate Read the Directions,” is placing out in Port Canaveral for now, expecting its next mission. The huge ship, which now has 11 rocket catches below its belt, transferred to the East Flee earlier this Twelve months, after receiving some sweet upgrades.
This day’s begin also became as soon as the foremost since August to characteristic a contemporary SpaceX booster. The engine topic quickly grounded SpaceX’s recent boosters, permitting the firm to house extinct rockets and its own Starlink web constellation. Within the month of October, SpaceX launched a chronicle 180 Starlink satellites, bringing the total quantity launched to nearly 900.
B1062 became as soon as the gigantic name of the expose this day, and this would perhaps moreover likely be the foremost Falcon 9 booster to defend two assorted GPS satellites to orbit; or no longer it’s scheduled to begin the subsequent one, one day next Twelve months. This would possibly perhaps occasionally moreover price the foremost time that a previously flown Falcon 9 will hoist indubitably such a developed world positioning satellites.
With the relaxation Starlink mission, which launched on Oct. 24, SpaceX hit a main milestone: 100 a success Falcon launches. This entire encompasses the total Falcon family, at the side of the pioneering (and lengthy discontinued) Falcon 1 and the currently operational Falcon Heavy. SpaceX tweeted out a video no longer too lengthy ago to commemorate the milestone.
Fairing recovery
One of SpaceX’s two fairing catchers, GO Ms. Chief, is ready within the recovery zone this evening. The 2 boats are geared up with big nets to make a choice the falling pieces of the rocket’s payload fairing, or nostril cone, after they are deployed at some level of flight. (SpaceX fairings come abet to Earth in two halves.)
GO Ms. Chief departed Port Canaveral on Wednesday (Nov. 4) ahead of this day’s begin. The vessel traveled solo this time as its counterpart, GO Ms. Tree, remained in Port in Florida. (The boat became as soon as damaged on a old mission and would perhaps perhaps presumably presumably peaceful be present process repairs.)
All over a prelaunch broadcast, SpaceX engineer Jessica Anderson announced that the firm would no longer be attempting a pick, nevertheless as a substitute would scoop up the fairing pieces after they land within the ocean. The boats have the functionality of catching falling fairings of their nets, or scooping them out of the water after they splash down. These efforts would perhaps perhaps presumably moreover peaceful occur roughly 45 minutes after liftoff.
With the abet of Ms. Tree and Ms. Chief, SpaceX has been a success in its attempts to reuse extra of the rocket, even reusing diverse fairings on multiple missions.
Up next for SpaceX is Crew-1, its first shriveled crewed mission to the Worldwide Region Standing for NASA. A assorted Falcon 9 rocket will ferry four astronauts to the gap for a six-month defend. That flight is decided to blast off from Pad 39A at NASA’s Kennedy Region Heart in Florida on Nov. 14 at 7: 29 p.m. EST (0029 GMT on Nov. 15).
