CAPE CANAVERAL, Fla. — SpaceX successfully launched its fourth batch of Starlink satellites into orbit and landed a rocket landing Wednesday following days of weather delays for the mission.

A sooty Falcon 9 rocket — which made its third flight with this launch — roared to life at 9:06 a.m. ET, lifting off from Space Launch Complex 40 at Cape Canaveral Air Force Station here in Florida. The rocket carried 60 Starlink satellites for SpaceX's growing constellation, the second such launch by the company this month.

Last week, strong upper level winds forced the private spaceflight company to postpone the Starlink-3 mission's launch. SpaceX then aimed for the backup launch date of Jan. 28, but rough seas where the drone ship was waiting may have thwarted any attempt at a landing.

The star of this mission, the Falcon 9 first stage dubbed B1051.3 by SpaceX, previously lofted a Crew Dragon capsule as part of the company’s uncrewed mission to the space station as well as a trio of Earth-observing satellites for Canada.

The Falcon 9 rocket that launched SpaceX's Starlink-3 mission landed safely on the company's drone ship "Of Course I Still Love You" after launching the Starlink-3 satellites into orbit on Jan. 29. It was the third launch for this rocket.

Following the successful launch, the rocket's first stage gently touched down on a SpaceX drone ship landing platform "Of Course I Still Love You" in the Atlantic Ocean, marking the company's 49th booster recovery.

SpaceX designed its souped up Falcon 9 rocket to fly as many as many as 10 times with only light refurbishments in between. The company has yet to fly a booster five times, but continues to rack up veterans with three or four flights, proving their capability.

Today's launch is part of SpaceX's goal of connecting the globe with its Starlink network. Each satellite is identical, weighing in at roughly 485 lbs., and is part of a larger network that aims to provide internet coverage to the world below. With this launch, it brings SpaceX's burgeoning constellation up to 240, making it the largest in orbit to date.

But SpaceX is not the only aerospace company with dreams of global connectivity. OneWeb launched its first set of six satellites in 2019, and Amazon hopes to launch its own constellation soon. However, SpaceX (with its own rockets) is the first to amass a sizeable constellation.

Elon Musk, SpaceX CEO and founder, has said the company will need at least 400 satellites in orbit to provide minimal coverage, and at least 800 to provide moderate coverage. With this launch, the private spaceflight company is over halfway to the minimal coverage mark and says service could begin sometime this year. When that happens, the first places to receive coverage would be portions of the U.S. and Canada.

SpaceX's Starlink project has one simple goal: to provide constant high-speed internet access to users around the world. Currently technology limitations often leave remote and rural areas without access; SpaceX wants to change that.

To access the internet, we rely on wireless cell towers or cables routed into our homes and offices. To that end, massive communications satellites will beam down internet coverage down from their orbital perched high above the Earth, in what's known as geostationary orbit (typically 22,000 miles up). The signal has to travel such a long distance, which translates to slower connections speeds.

By operating at a lower altitude (and with more satellites), SpaceX says it can mitigate this issue and provide reliable coverage at an affordable price.

Not everyone is thrilled about the idea of SpaceX's new mega-constellation. Astronomers have voiced concerns that the satellites could interfere with crucial scientific observations.

SpaceX's Starlink satellites stand out as they march across the night sky. That's because they’re incredibly bright, appearing as a train of bright dots as they orbit. Just how bright they were shocked and concerned scientists. Many were nervous that the Starlink constellation (and the others that will follow it) could interfere with their work.

Astronomers rely on ground-based telescopes to take long-exposure images of astronomical objects they want to study. When something bright passes in front of the telescope's field of view, it can obscure the image, and the observer has to figure out what caused it.

Musk and SpaceX listened to the concerns of astronomers and have experimented with ways of reducing the satellite’s brightness. One satellite in the previous batch was coated in a special material to make it appear darker in orbit.

Once the dark coating has been tested, SpaceX will decide how effective it is and whether or not the whole fleet will receive the same treatment.

During live launch commentary today, Starlink engineer Lauren Lyons said the satellite with that dark coating is still making its way to its final orbit, so more time will be needed for SpaceX to complete its tests.

SpaceX has proven that it can successfully reuse its rocket boosters, but the company wants to take the notion of reusability one step further by recovering and refurbishing payload fairings.

The rocket’s nose cane is comprised of two halves (also known as payload fairings), which are designed to protect the payload during launch. SpaceX has equipped each fairing with its own navigation system that allows it to glide gently back to Earth. The company hopes this will facilitate the recovery and reuse of the fairing.

With each piece fetching roughly $3 million, SpaceX hopes to save some money by reusing them on future flights. To that end, the company has outfitted two of its recovery vessels with giant nets. Acting as mobile catcher's mitts, SpaceX hopes that it will be able to snag a fairing in each net.

To date, GO Ms. Tree (the vessel formerly known as Mr. Steven) has made two successful catches. The second boat, GO Ms. Chief has yet to snag a falling fairing.

Editor's note: This story will be updated once SpaceX announces updates of Starlink satellite deployment and the results of its payload fairing capture attempt.
