SpaceX sends up Starlink satellites Sunday night from Cape Canaveral Space Force Station
The Starlink 12-20 mission lifted off at 9:24 p.m. EST from Launch Complex 40. The SpaceX mission marked the 20th orbital rocket launch of the year thus far from Florida's Space Coast.
Sunday's prime-time liftoff occurred during stellar meteorological conditions. The Space Force's 45th Weather Squadron had forecasted a 90% chance of "go for launch" weather, with liftoff winds and cumulus clouds representing slim threats.
Cape Canaveral: Is there a launch today? Upcoming SpaceX, NASA rocket launch schedule at Cape Canaveral
Ten minutes before liftoff, rocket fueling was well underway at the pad. SpaceX crews rattled off a list of key countdown milestones before liftoff. T-minus:
7 minutes: Falcon 9 begins engine chill prior to launch.
1 minute: Command flight computer begins final prelaunch checks; propellant tank pressurization to flight pressure begins.
45 seconds: SpaceX launch director verifies 'go for launch.'
3 seconds: Engine controller commands engine ignition sequence to start.
0 seconds: Falcon 9 liftoff.
Sunday's launch marked the Falcon 9 first-stage booster's fifth flight, SpaceX reported. This booster previously launched GOES-U, Maxar 3 and two Starlink missions.
Following stage separation, the booster returned to Earth for a landing atop the SpaceX drone ship Just Read the Instructions in the Atlantic Ocean.
Looking past Sunday's liftoff, SpaceX is targeting early Wednesday morning for another Falcon 9 launch on a Starlink mission, a Federal Aviation Administration operations plan advisory shows.
The 4½-hour launch window extends from 1 a.m. to 5:31 a.m. Live FLORIDA TODAY Space Team coverage kicks off 90 minutes before liftoff at floridatoday.com/space.

Musk Races to Fix SpaceX's Starship After Failures, Explosions
When one of SpaceX's Starship vehicles burst into flames during a routine fueling test in June, the Elon Musk-led company decided it was time to bring in reinforcements. Shortly after the incident, roughly 20% of the engineering group working on the company's flagship Falcon 9 program were reassigned for six months to Starship, a reusable rocket Musk hopes will someday carry humans back to the moon and to Mars, according to people familiar with the company's planning. Bloomberg News Space Reporter Loren Grush joins Bloomberg Businessweek Daily to discuss. (Source: Bloomberg)

Watch live: NASA briefs press on completed SpaceX CREW-10 mission on ISS
NASA's Crew-10 astronauts will brief reporters Wednesday afternoon on their nearly five-month SpaceX mission aboard the International Space Station. The crew — which included NASA's Anne McClain and Nichole Ayers, the Japan Aerospace Exploration Agency's Takuya Onishi and Russian cosmonaut Kirill Peskov — returned to Earth earlier this month, splashing down off the coast of San Diego. 'The crew spent 146 days aboard the orbiting laboratory, traveling nearly 62,795,205 million miles and completing 2,368 orbits around Earth,' NASA wrote in its news release. 'While living and working aboard the station, the crew completed hundreds of science experiments and technology demonstrations.' McClain, Ayers and Onishi will take questions from the media at Johnson Space Center in Houston, Texas. The press conference is scheduled to begin a 4:15 p.m. EDT.

Starship launches could delay Florida flights up to 2 hours, FAA says
As regulators weigh SpaceX's plans to launch its massive Starship rocket from Kennedy Space Center, federal documents warn those flights could ripple through Florida airspace, forcing ground stops at multiple airports, reroutes, and delays of up to two hours. Even after launch, reentry of Starship's two stages could require ground stops at some of the busiest airports in the country, according to a draft environmental impact statement (EIS) released by the Federal Aviation Administration this month. Florida airports affected by the launches may include Orlando International, Miami International, Tampa International, and Fort Lauderdale/Hollywood International. Average delays could be as long as 40 minutes to 2 hours for launches and Super Heavy booster landings, and 40 minutes to one hour for Starship reentries. Diversions and cancellations are possible, the FAA said in a companion slide deck. To manage risk, the FAA would establish Aircraft Hazard Areas (AHAs) over potentially impacted zones, as it does for commercial space launches today. Depending on the Starship flight trajectory, those zones could overlay routes above the Atlantic, parts of the Gulf of Mexico, the Caribbean, and airspace in several Central American countries. 'AHAs may necessitate the closure of dozens of coastal and deep-water oceanic airways over the Atlantic Ocean, requiring substantial aircraft rerouting to avoid the AHAs,' the draft EIS says regarding Starship launches. Tampa International Airport spokesperson Emily Nipps told TechCrunch the airport has not been involved in any briefings or procedural planning with the FAA or SpaceX, so far. However, a day after TechCrunch sent its inquiries to the relevant airports and the FAA, Nipps said the airport was informed it would be having those discussions 'soon.'

San Francisco | REGISTER NOW 'Whether that changes anything for us operationally, I don't yet know,' she said. A spokesperson for Miami International said they have not received any briefings on possible ground stops. SpaceX has been launching its flagship Falcon rockets from the Florida coast for years, and that cadence has sharply increased since 2020. Despite launching over 80 Falcon rockets from the Eastern Range last year, these launches don't typically interrupt commercial airlines. But the Falcon rockets are substantially different from Starship: Falcon's smaller size means a smaller possible footprint for debris in the case of an anomaly, and the Falcon launches are at this point predictable and mature. Starship is in a much earlier stage of development, with vehicles still occasionally blowing up during both ground tests and orbital flights. Indeed, the draft EIS notes that the size of airspace closures may vary with each Starship mission, and that it could shrink as the vehicle becomes more reliable. An FAA spokesperson said the agency has already engaged with aviation organizations, and worked with SpaceX to develop notional launch and reentry trajectories. Prior to launch, the agency will also distribute a final Airspace Management Plan. The FAA relies on a number of factors, including the number of affected passengers, launch window duration, and major holidays when determining when a space launch can proceed, the spokesperson added. Starship is SpaceX's next-generation launch system designed for travel to the Moon and Mars. The 400-foot-tall rocket is composed of two stages: an upper stage, also called Starship, and a Super Heavy booster. Both stages are designed to be fully reusable and rapidly refurbished for high-cadence satellite delivery and missions to deep space. Today, SpaceX conducts all Starship launch activities from Starbase in south Texas. But the company is looking to expand operations to NASA's Kennedy Space Center, prompting the environmental review. That review is conducted by the FAA in cooperation with NASA, the Air Force, the Fish and Wildlife Service, and other federal agencies. The draft EIS analyzes up to 44 Starship launches per year, which could include up to 44 Super Heavy booster landings and 44 Starship landings. Super Heavy could land back at LC-39A, the launch pad at KSC, on a droneship, or be expended in the Atlantic. Starship landings could likewise occur at the pad, on a ship, or as water splashdowns with recovery in the Atlantic, Pacific, or Indian Oceans. The FAA said in the draft EIS that while temporary airspace closures may impact commercial airlines and other stakeholders, 'mitigation strategies such as pre-coordinated reroutes, dynamic scheduling, and time-based traffic flow management could reduce operational burdens.' Today, FAA uses a prototype tool called Space Data Integrator, which ingests real-time flight data from SpaceX and other operators to shrink the amount of time airspace is closed. The regulator says it wants to develop more tools to beef out its situational awareness capability, and each time Starship launches it will get more data on its operations. The U.S. Space Force is running a parallel environmental review at neighboring Cape Canaveral Space Force Base that analyzes up to 76 annual Starship launches. While the draft EIS for that site states Starship launches would result in airspace closures, it says details of the closures are not yet known because the site is expected to take months to prepare.
