CAPE CANAVERAL, Fla. — A SpaceX Falcon 9 rocket launched a brand new fleet of Starlink web satellites into orbit alongside two rideshare satellites Saturday night (Might 15), earlier than sticking a shocking touchdown at sea.
The veteran Falcon 9 rocket blasted off from Pad 39A at NASA’s Kennedy Area Middle right here in Florida at 6:56 p.m. EDT (2056 GMT), marking the corporate’s 15th launch of the 12 months. It additionally marked the eighth flight for this specific Falcon 9.

The profitable liftoff marked the third time SpaceX launched one among its 229-foot-tall (70 meters) workhorse Falcon 9 rockets inside as many weeks, as the corporate works to increase its burgeoning broadband constellation.
Roughly 9 minutes after liftoff, the rocket’s first stage returned to Earth, touching down on SpaceX’s drone ship “Of Course I Nonetheless Love You,” for a eighth profitable touchdown. A digital camera aboard the rocket stage captured spectacular video of the entire descent back to Earth.
It was a windy day on the area coast however blue skies over the launch pad made for fairly the present. Because of the few scattered clouds hanging within the sky, the roar of the Falcon appeared louder because it climbed to orbit to this observer.
SpaceX has been profiting from its fleet of flight-proven boosters, as all of its missions thus far in 2021 have flown on a reused rocket, with 12 of these missions carrying Starlink satellites.
As we speak’s flight, known as Starlink 27, is a bit distinctive in that SpaceX is sharing the payload fairing with paying clients. Tucked alongside a stack of 52 Starlink satellites are two extra passengers: a nanosatellite for Tyvak and a radar satellite tv for pc for Capella Area.
These two satellites will deploy previous to the stack of SpaceX’s personal.
That is the second of three launches which are scheduled at present as Rocket Lab tried to launch its 20th mission, known as Working Out of Toes from Mahia Peninsula, New Zealand at 7:11 a.m. EDT (1111 GMT). An anomaly throughout the Electron’s second-stage ignition and all of the satellites on board had been misplaced. Rocket Lab is working carefully with the Federal Aviation Administration (FAA) to find out precisely what occurred.
Following SpaceX’s on-time liftoff, NASA is planning to launch a small sounding rocket out of Wallops Flight Facility in Virginia.
That rocket, a Black Brant XII sounding rocket, will blast off at 8:03 p.m. EDT (0003 GMT), carrying a payload known as KiNet-X. The flight may produce some dazzling sights for onlookers alongside the East Coast and Bermuda. Here is how one can watch that reside on-line, beginning at 7:40 p.m. EDT (2340 GMT).
NASA has a 40-minute window to launch the mission, which has been delayed a number of occasions. The experiment is designed to discover vitality transport in area. The mission will examine how vitality and momentum are transported between areas of area which are magnetically linked.
A rising constellation
SpaceX’s Starlink megaconstellation was created with a purpose to present web protection to the world whereas serving as a way to fund its deep area ambitions. To that finish, firm engineers designed a fleet of flat-paneled broadband satellites to fly over the Earth, beaming down web protection to customers who can entry the service through a compact person terminal.
The corporate is focusing on customers in distant or rural areas who presently have little-to-no web connectivity, however customers throughout the globe can subscribe to the service.
With Saturday’s profitable launch, SpaceX has lofted greater than 1,600 Starlink satellites into orbit, which fits past the corporate’s preliminary quota of 1,440. The corporate has official approval for hundreds extra and is predicted to roll out full industrial service later this 12 months.
At present, Starlink remains to be in its beta-testing section with customers around the globe placing the service via its paces. The corporate has additionally opened up its web site to start taking preorders and says that so way over 500,000 customers have signed up.

Fly, fly once more
The booster utilized in Saturday’s launch, known as B1058, is one among SpaceX’s frequent fliers. The veteran launcher now has eight launches and landings below its belt as the corporate continues to push its Falcon 9 rockets to the restrict.
This frequent flyer, adorned with NASA’s iconic worm brand, made its debut in Might 2020 with the launch of two NASA astronauts to the Worldwide Area Station on the Demo-2 check flight. The booster was SpaceX’s first to be emblazoned with the retro-looking NASA brand. The as soon as vibrant crimson brand is now nearly black following its eight journeys to area and again.
After B1058 made historical past with the primary astronaut mission to launch from Florida for the reason that finish of the shuttle program in 2011, the booster additionally launched a communications satellite tv for pc for South Korea’s army; Transporter-1, the biggest payload of small satellites ever delivered to orbit; an upgraded cargo Dragon capsule; and three completely different Starlink missions.
SpaceX has been utilizing its beforehand flown boosters with essentially the most miles to move its personal satellites into area. That means the corporate can push its fleet of Falcon’s to the restrict whereas additionally studying as a lot concerning the wear-and-tear every automobile receives throughout launch.
That is the 119th total flight for Falcon 9, and the 65th flight of a refurbished booster. Actually, each single SpaceX launch thus far in 2021 has been on a flight-proven rocket.
In 2018, SpaceX debuted the rocket we see at present, a model of Falcon 9 often called Block 5. This extra succesful Falcon 9 has ushered in an period of speedy reusability for the corporate, enabling SpaceX to launch extra rockets than ever earlier than.
Three years in the past, SpaceX CEO and Founder, Elon Musk, informed reporters that the corporate anticipated every Falcon 9 to fly 10 occasions with few refurbishments in between flights, and as many as 100 occasions earlier than retirement.
SpaceX not too long ago achieved that milestone with one other booster — B1051. That launcher was the primary to achieve 10 flights and isn’t stopping any time quickly. In line with Musk, 10 flights will not be a tough restrict or magic quantity. As the corporate continues to refine its refurbishment course of, it is going to proceed to push every Falcon to its breaking level, he stated.
Having a fleet of flight-proven rockets at its disposal permits SpaceX to maintain up with its speedy launch cadence. Nevertheless, SpaceX chooses to fly its personal payload on boosters with a excessive flight rely, saving its newer boosters for paying clients.
Lately, each NASA and the U.S. Area Pressure not too long ago granted the corporate approval to fly their payloads on reused rockets, with SpaceX flying its first crew of astronauts on a reused rocket on April 23. That mission was successful and later this summer season, SpaceX will fly an upgraded GPS satellite tv for pc for the U.S. Area Pressure on a reused rocket as effectively.
To facilitate reuse, SpaceX outfitted its Falcon 9 with some upgrades earlier variations didn’t have, together with a extra sturdy thermal safety system, a extra sturdy interstage (the half that connects the rocket’s first stage to the higher stage), titanium grid fins and extra highly effective engines. These key enhancements, together with two drone ships on the identical coast, have enabled SpaceX to launch and land extra rockets.
SpaceX additionally not too long ago added a brand new boat to its fleet of restoration vessels. Named the Shelia Bordelon, can be retrieving the fairings after they fall again to Earth with the assistance of its onboard crane. The boat will haul the fairings again to port, the place they’ll possible fly once more quickly.
