Musk emphasized that while SpaceX has taken significant measures to make sure the Starlink satellites work, the early spacecraft have lots of new technology and could fail. The exact number depends on the success of this first mission, she said. SpaceX intends to do three to seven Starlink launches this year, counting this mission, according to Gwynne Shotwell, company president and COO. Once the constellation reaches 1,000 spacecraft, it will become “economically viable,” he said. Musk said Starlink will be able to start partial service with around 400 satellites, and will reach “significant operational capability” at around 800 satellites. SpaceX CEO Elon Musk, in a call with reporters last week, said the Starlink satellites will also automatically maneuver around orbital debris by using Air Force tracking data uploaded directly to each spacecraft. The lower orbit means less signal lag, and also ensures that atmospheric drag will pull satellites down in five years or less, reducing the risk of space debris from any damaged or defunct spacecraft, SpaceX said. Federal Communications Commission in late April to operate some of its satellites at that lower orbit instead of 1,150 kilometers as previously planned. From there, the spacecraft will use Krypton-fueled electric propulsion thrusters to reach their target operational altitude of 550 kilometers. The launch deployed the Starlink satellites into a 440-kilometer orbit. ![]() The satellites collectively weighed 13.6 metric tons, making this launch the heaviest mission for SpaceX to date. SpaceX deployed the Starlink satellites collectively from the upper stage, allowing the satellites to drift off using their own inertia instead of springs or another conventional deployment mechanism. ![]() The same Falcon 9 first stage previously launched the Telstar 18 Vantage satellite to geostationary orbit in September 2018, and 10 Iridium Next satellites to low Earth orbit this January. SpaceX landed the booster that launched the satellites 9 minutes after liftoff on the droneship “Of Course I Still Love You,” in the Atlantic Ocean. Collectively they are expected to deliver 1 terabit per second of usable capacity, and 2.5 to 3 terabits per second of total capacity. The 60 satellites mark the beginning of SpaceX’s deployment of a global internet megaconstellation intended to generate more revenue to fuel the company’s interplanetary ambitions.Įach Starlink satellite launched May 23 weighs roughly 227 kilograms. ![]() Upper-level winds delayed the Starlink launch again last week, as did additional time SpaceX elected to take for software checks on the satellites. SpaceX previously planned the launch for early May, but the mission was pushed back due to knock-on delays from an earlier resupply mission to the International Space Station that had its own schedule slips. Eastern, and deployed the satellites into a low Earth orbit a little over an hour later. The rocket took off from Cape Canaveral, Florida at 10:30 p.m. WASHINGTON - SpaceX launched the first 60 satellites for an internet constellation that could ultimately number 12,000 on a Falcon 9 rocket Thursday night. ![]()
