SpaceX's Starlink satellite internet constellation is preparing to reach another major milestone, becoming one of the few internet services to offer laser coverage to crew members flying aboard the Crew Dragon spacecraft. Over the past few years, SpaceX has become a one-stop provider of space-related services. The company's Falcon 9 rockets can launch a variety of payloads into different orbits and carry out crewed missions to the International Space Station (ISS) and other destinations.
Meanwhile, the company's Crew Dragon spacecraft is one of the few flying both private and government astronauts, and its Internet service Starlink uses low-Earth orbit (LEO) satellites to beam Internet connections around the world.
Starlink will now provide internet connectivity to astronauts on the PolarisDawn mission.
SpaceX's Dragon spacecraft is making rapid progress, opening up new avenues for private space flight. Previously, due to a number of factors, space travel was largely limited to astronauts trained and funded by space agencies. The biggest factor is the lack of private spacecraft, as vehicles like the space shuttle and Russian Soyuz are operated by space agencies.
However, since CrewDragon is developed and operated by SpaceX, private astronauts are allowed to travel into space. The "Manned Dragon" Inspiration 4 mission that took off in September 2021 was the first time a crew composed of all private astronauts entered space, and SpaceX's flagship crew spacecraft became the first fully commercially operated International Space Station (ISS) mission in April 2022, creating another milestone.

After the Inspiration 4 mission, billionaire Jared Isaacman, the mastermind behind the flight, purchased seats for the Crew Dragon to be used for part of the Polaris mission. Project Polaris, also designed to raise funds for St. Jude, includes three flights. Among them, the first two will be carried out by Crew Dragon, and the third will be carried out by Starship.
While neither Polaris nor SpaceX has announced a specific launch date for the Polaris Dawn mission, the first of three flights, the flight is expected to take place in "early 2024." The mission will mark several firsts for private spaceflight, perhaps the most important of which is a spacewalk. Government astronauts regularly perform spacewalks on the International Space Station as part of their responsibilities to repair and maintain the space station. If the Polaris Dawn astronauts also perform spacewalks, it will be the first time that private astronauts have performed spacewalks.
In addition, another initiative of the "Polaris Dawn" mission is to test the "Starlink". SpaceX recently revealed that the Starlink satellite internet constellation is using more than 8,000 lasers for inter-satellite communications, with each laser link capable of transmitting 100Gbps of data. It also announced that the latest Starlink launch was the first time a satellite was equipped with a new generation of lasers.
Following SpaceX's announcement, Polaris' communications team outlined that the Polaris Dawn crew will be the first to test Starlink on human spaceflight. Details on its website reveal that the crew will be the first to test "laser-based Starlink communications in space," another achievement for SpaceX's satellite internet constellation.
