SpaceX tests Falcon 9 rocket for next Starlink satellite fleet launch

CAPE CANAVERAL, Fla. — SpaceX has fired up the rocket that will ferry the company's next batch of Starlink satellites into space.

That rocket is expected to launch 60 Starlink internet satellites into orbit no earlier than Thursday (April 23) from the historic  Launch Pad 39A at NASA's Kennedy Space Center here. On Friday (April 17), the company test-fired the first stage of Falcon 9 booster to ensure the rocket is ready for launch, the company said on Twitter.

The test, called a static fire, is a typical prelaunch test for SpaceX missions and sent smoke billowing from the 229-foot tall (70-meter) rocket as its nine Merlin 1D engines briefly ignited. The upcoming launch, called Starlink 6, will mark the fifth Starlink mission this year and the company's seventh batch of operational satellites — launched 60 at a time — since 2019.

The Starlink 6 mission's veteran Falcon 9 rocket rolled out of its hangar and went vertical on the launch pad in advance of the test-firing of its first-stage engines on Friday morning. During the test, teams loaded the Falcon’s super-chilled propellants — kerosene and liquid oxygen — into the rocket and then briefly ignited the first stage’s nine Merlin 1D engines.

The engines briefly fired at 12 p.m. EDT (1600 GMT), generating more than 1 million pounds of thrust while the booster remained firmly on the ground. Engineers reviewed the data before deciding to proceed with the Falcon 9’s planned launch attempt Thursday afternoon. 

"Static fire test of Falcon 9 complete — targeting Thursday, April 23 at 3:16 p.m. EDT, 19:16 UTC, for launch of 60 Starlink satellites from LC-39A in Florida," SpaceX tweeted shortly after the test.

The rocket featured in the upcoming flight is a thrice-flown booster, having previously launched the Crew Dragon capsule on its first journey to the space station in 2019, a trio of Canadian Earth-observing satellites, and the fourth Starlink mission earlier this year. 

The Starlink 6 launch will mark the fifth time a SpaceX booster will fly four times. The company's previous Starlink mission also featured a veteran booster. However, during that flight, one of the booster's nine engines cut out during its ascent. Falcon 9 is designed to handle this type of engine failure and deliver its payload safely to orbit. However, the booster was unable to successfully land on the drone ship. 

This upcoming mission is also unique in that it's the second to feature another key piece of recycled hardware: the rocket's nose cone. Also called the payload fairing, the clam-shelled covering is designed to protect the payload as it rockets through the atmosphere. Once the craft is above Earth's atmosphere on its way to orbit, the two pieces are jettisoned and plummet back to Earth. 

Historically, the fairings have been a "one-and-done" component; once they do their job, the pieces are discarded in the ocean, never to be seen again. But SpaceX aims to change that and save $6 million per flight by reusing even a single fairing.

To that end, the California-based rocket manufacturer has outfitted two boats with giant nets that act as mobile catcher's mitts. SpaceX has also outfitted each fairing with a parachute and onboard computer system that will steer it back to Earth and (hopefully) into the outstretched nets of the ships GO Ms. Tree and GO Ms. Chief. SpaceX has worked steadily to reuse as much of its Falcon 9 rockets as possible, and has made 50 first-stage landings in recent years.

While catching the falling fairings can be a challenge, SpaceX has also been scooping them out of the water and refurbishing them. Shrouding the stack of 60 Starlink satellites is the second set of payload fairings to be reused. 

Starlink 6 is the first time SpaceX has used a fairing half that was caught in a net. For this flight, one half was caught by GO Ms. Tree and the other was scooped out of the ocean. It's also the third flight to feature recycled fairing pieces. 

According to SpaceX, the fairing halves used in this flight were first flown on the AMOS-17 mission, which launched in 2019. The boats are expected to leave Port Canaveral a few days prior to launch, so they can be in position and ready to make another catch.

    No longer a fan of Musk... I had to deal with dozens of these man-made unnecessary sats every night now. Does Musk care? Not much. It's all about making money to send him to Mars and the heck with us ants on Earth.

    It's an exciting time to be alive. I truly envy the 20 and 30 somethings who are making this happen.

    https://arizonahomeopathic.org/2019/02/06/5g-a-toxic-assault-on-the-planetary-web-of-life/What isn’t acknowledged in all this media hype is that this technology may present as an unprecedented negative environmental effect. The planet, plants, animals, humans, and all life on Earth is in jeopardy. With millions of new 5G base stations, also known as cell towers or small cells, from Earth, and 20,000 new satellites from space simultaneously beaming hundreds of times more powerfully focused RF/MW radiation of pulse modulated millimeter waves, with a much higher absorption rate than 4G/3G/2G centimeter waves, through walls, trees, and human bodies day and night, we’re talking about an estimated of 200 billion transmitting objects, which will be part of the Internet of Things (IoT) by 2020.

    This could be a large-scale and complete disaster for the human race. Part of what the globalists are trying to do is deny that there’s a problem with non-ionizing frequencies, even though, as already stated, more than 10,000 papers are saying there are indeed multiple levels of health problems. According to the actual scientific research, there’s clear evidence of damage of DNA, cells, and organs in a wide variety of ways and increased disease processes, including cancer, heart disease, diabetes, and a host of electromagnetic diseases. If 5G comes to fruition, no person, no animal, and no plant will be able to avoid the 24/7 exposure to levels of RF/MW radiation that are at least 100 times greater than current levels. 5G will threaten to provoke severe and irreversible effects in humans and also damage to all of Earth’s ecosystems.
