Interstellar travel is already the embodiment of the “giant of attack” in space, even though it’s not ready to go. When “60 Stars” became synonymous with Starlink, SpaceX had already planned its 2020 plan for the low-orbit broadband constellation. With four to six more launches, users across the United States are expected to be the first to enjoy the high-speed networks provided by satellite broadband.
SpaceX’s “First Launch of the New Year” was locked at 10:19 a.m. Beijing time on January 7, when 60 Starlink satellites aboard the Falcon 9-1.2 launch vehicle carried out their third launch mission at the Canaveral Air Force Station in the United States and completed the separation of the Stars and Arrows about an hour later.

Meanwhile, Musk, the “space maniac” who flew to Shanghai, China, switched identities to attend the launch of Model Y’s mass production in China as Tesla’s CEO. Perhaps immersed in the joy of the opening of the double-fire gun, he danced the entire field with an original “Mars Disco” during the home-made Model 3 delivery ceremony.
Comparing the difficulties of the new car, deer-by-deer space will only be more difficult. Whether it’s Starlink’s space network communications or the starship’s landing on Mars, the ultimate return is based on Musk’s pioneering and hard-working spirit.
With a higher outlook for 2020, SpaceX’s imprint over the past year may be worth remembering.
Line-to-face space-based Internet
The New Year’s eve came after SpaceX set a new global record for the delivery industry with 52 consecutive rocket launches. Of the 13 launches completed in 2019, the Falcon 9 has 11 launches, and two more are heavy-duty Falcons, which are connected by three core boosters.
Compared to its unbeaten record of 52-0, SpaceX is another high-profile achievement in 2019, when it is part of its launch mission in May and November in the “One Arrow 60 Star” low-orbit broadband constellation. A total of 180 satellites were sent into space after the launch of the third batch of Starlink satellites on January 7 this year.
The initial launch, conducted in May, focused on the unusual deployment of the 60 satellites. The simplified flat design, a two-column, 30-in-a-row stack, is deployed in a different way than the traditional “formal approach.” “This kind of “weird” deployment is like the process of spreading a deck of cards on a table, ” Musk says figuratively. “
The day after the satellite’s launch, Musk tweeted that the satellite was “all right.” The 60 satellites were put into a scheduled orbit of 440 km by the Falcon 9 rocket as originally planned, and then into the final orbit of 550 km through the xenon thruster.
The man-made constellation wonders that rotate around the earth have been captured by Dutch satellite tracker Langbrook, and from the video he released, at least 56 objects are lined up in the sky, like a string of pearls passing through the night sky.
Musk also became the chief experiencer for the Starlink program. He assembled a “Starlink” terminal at home. In the early hours of October 22, he posted a message on his Twitter account of his 29 million followers: “Wow, that’s a good way!! To show that you were sent this tweet through space via the Starlink satellite.
On the same day, SpaceX President and COO Shutterwell said the company is confident it will begin providing broadband services in the U.S. through the Starlink constellation by mid-2020. This requires only 6 to 8 satellites to be launched. However, the biggest difficulty in implementing this plan is not the launch of satellites, but how to overcome the design and engineering challenges of user terminals.
There is no doubt that the Starlink program is by far the largest mega-constellation of magnitude, with 12,000 Starlink satellites approved by the Federal Communications Commission (FCC). In fact, if you achieve global coverage, you only need to launch 24 times.
While officials and Musk himself have not yet determined whether so many satellites are needed, it provides a necessary support for SpaceX’s creation of the world’s largest low-orbit broadband constellation, given “more capacity for users” and the option of providing customized services to users.
The measure-winning style may be effective, but SpaceX’s renewed expansion is controversial. In mid-October, SpaceX applied to ITU for a spectrum application for an additional 30,000 Starlink satellites, a move that was criticized by stargazers and astronomers for concerns that SpaceX would deploy thousands of satellites in space. It is very likely to cause inconvenience to daily astronomical observation and other activities.
Compact design and stacking take advantage of Falcon 9’s launch capabilities . . . Starlink
Fortunately, SpaceX President and Chief Operating Officer Shortwell told the media on December 6, 2019 that one of the next batch of 60 Starlink low-orbit broadband satellites scheduled to be launched by the end of December (extended to January 7, 2020) will be specially coated to reduce reflections, and thus Reduces the likelihood of interference with astronomical observations. However, “it was just an experiment to find the best solution.” “
Starlink plans an unprecedented number of satellites. Apart from addressing the adverse effects of satellites on astronomical observations, how to properly dispose of obsolete satellites is a headache for government and industry officials. More than a month after the first Starlink satellite son-off, three satellites were outofed.
At the World Security Fund’s Space Sustainability Summit at the end of June last year, mPs estimated at a scrap rate of 5%, fearing that the giant constellation of the proposed network of thousands of satellites would “leave” hundreds of abandoned satellites in low-Earth orbit.
To prevent abandoned satellites from polluting space or even accidents, SpaceX was prepared early in its design. Officials say abandoned satellites that orbit the Earth for a while will eventually be pulled down by the Earth’s gravity and cremated in the atmosphere to support space exploration companies’ commitment to clean up the space environment.
The Falcon 9 launch vehicle, which is docked at the plant, waits to leave the factory.
Low-cost exclusive launch advantage
Today, vertical take-off and landing technology is the external business card of spaceX launch vehicles, and its reliability and technical maturity have been proven in the practice of multiple reusudoning of a stage rocket, as illustrated by the continuous launch and recovery of 52 times. The third batch of Starlink satellites, launched on January 7 this year, uses a “four-handed rocket” that has been launched three times before.
The rocket was first launched in September 2018, when the Telstar 18 VANTAGE communications satellite was launched from Cape Canaveral and landed on a SpaceX unmanned barge in the Atlantic Ocean. The second launch, to take place in January 2019, puts 10 xenon voice and data relay satellites into orbit and lands again on unmanned barges at sea. The third launch, the first of its Starlink satellites in May 2019, finally landed on the SpaceX recovery ship and was refurbished to wipe the hands of the fourth launch mission.
In fact, SpaceX’s “four-hand rocket” isn’t the only one. The Falcon 9-1.2 rocket, which was used to launch the second batch of Starlink satellites as early as November 11 last year, was the focus of attention for the first reusable rectifier and the fourth reusable first-stage rocket.
Prior to that, the first-stage rocket was launched on July 25, 2018 and October 8, 2018 at Vandenberg Air Force Base, the “Next Generation” 10-Star Launch and the Argentine Earth Observation Satellite, and the Indonesian communications satellite and Israel’s Genesis on February 21, 2019 at Cape Ka. “The lunar lander is launched.
Later, Musk said, the 5-type arrow was designed to be used 10 times “without routine refurbishment” and 100 times if “proper routine maintenance” was required.
Not only did SapceX launch a worldwide “satellite broadband” boom with Starlink satellites, becoming the owners of the world’s first fleet of commercial satellites, but it also reduced costs through a series of technological innovations that made SpaceX’s rocket launch offers attractive. Among them, SpaceX seizes the advantages of rocket vertical take-off and landing recovery technology, through the multiple-use rocket significantly save slower launch costs, improve the frequency of launch. This means that Once launch offers are lowered to stimulate demand, SpaceX will also be able to cope with a growing number of satellite customers.
Musk found a commercial innovation scenario for the Falcon 9, a service called “SmallSat rideshare” announced last August that it would offer customers the opportunity to “space carpool” in existing near-Earth orbit missions to help them successfully send satellites into space.
SmallSat rideshare offers faster, more affordable satellite launch into orbit than its competitors . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The biggest difference with the ride in the past is that SpaceX has helped small satellites move away from the constraints of the time of the main satellite launch, which is when the launch time is no longer subject to the main satellite. As long as the satellite company makes an advance appointment, it can launch on time at the optional time given by SpaceX.
SpaceX’s official account said on social media that the stand-alone business offers industry-leading, exclusive services to small satellite manufacturers at a cost of just a fraction of the cost of traditional missions. The service will be available from March 2020, with at least one launch per month, a 200-kilogram small satellite charge starting at $1 million, with a minimum price and a 60-star cost. To get the most affordable price, you need to make an appointment at least one year in advance.
The first customer to sign up was Momentus, a sky-high transportation company that will take its “vibrant ride” tugboat into space on a future exclusive single-handed launch mission.
Kepler Communications, a Toronto-based satellite internet company, announced on December 11, 2019 that it had ordered SpaceX’s 400-kilogram single launch capability to launch its IoT Cube star next year. The price of the single launch contract is “roughly in line” with Space Exploration’s offer of $1 million for a 200-kilogram bid.
As the future of the planet’s shuttle progresses,
Since its inception, SpaceX’s main goal has been to help make humans a multi-planetary species. Musk hopes to create a vehicle that would reduce the price of travel to Mars to $200,000.
On September 18, 2018, SpaceX signed a contract with Yusaku Maezawa, a 43-year-old former founder of Zozotown, Japan’s largest fashion online site. The entire “overweight” giant rocket was sold, becoming the first passenger to sail around the moon. He plans to invite six to eight artists from around the world to fly around the moon in 2023.
As a new delivery system to replace the active Falcon 9 and heavy falcon, the fully reusable “overweight” giant rocket and the “Starship” passenger vehicle, shouldering the burden of heading to the moon and migrating to Mars, are far more difficult and costly to develop than the Falcon 9 and the Heavy Falcon.
Take SpaceX’s manned Mars spacecraft, which is supposed to transport astronauts to Mars at an expected cost of $10 billion. You know, SpaceX’s revenue has remained between $2 billion and $2.5 billion over the past two years. Even so, Musk has not stopped the project for burning money.
On March 2, 2019, the Falcon 9 rocket launched space x 2019 with spaceX’s second-generation Dragon spacecraft, the Manned Dragon, and actively docked it 24 hours later. Although it was an unmanned test flight, the manned Dragon spacecraft, which can carry seven astronauts, as the largest manned spacecraft in service, was the United States, which sent humans to the moon six times after the shuttle’s dismal retirement in 2011, finally restored its ability to send humans into space after an eight-year long gap period.
Unfortunately, the “human Dragon” spacecraft exploded on April 20, directly affecting NASA’s plan to restart the astronauts’ mission. At the same time, a manned test flight code-named “Verification” 2, which was scheduled for July 25, was repeatedly delayed because of the accident.

The starship MK1, which stands in the night sky, bursts on top of the head during a ground stress test in Texas on November 21, 2019. Each experiment is an attempt by man to realize the dream of colonizing Mars. And every failure has failed to bring down Musk, who is eager to see the moon.
Since 2002, Musk has experienced SpaceX’s frequent bankruptcies, hard-to-turn-overs, despair and physical and mental exhaustion. The company has created a number of monuments and hit rock bottom several times. “We know it’s going to be tough, or it’s not going to be called rocket science,” Musk used to inspire employees.
“We’ve got to pick ourselves up, pat the dust on our bodies and move on, and there’s a lot of work ahead to be done.” Musk, who has not closed his eyes for more than 20 hours, still said to his staff in a gritty and passionate tone, “Personally, I will never give up, never.” He told his colleagues that if he stood with him, he would win the final.
