SpaceX is making ready to launch its first Starlink mission from Cape Canaveral House Drive Station in additional than two weeks. The final time the corporate tried to launch the Starlink 10-2 mission, it encountered a uncommon scrub because the Falcon 9’s first stage Merlin engines started firing.
Liftoff of the rescheduled flight is about for 1:15 p.m. EDT (1715 UTC) from House Launch Advanced 40.
Spaceflight Now could have dwell protection starting about an hour previous to liftoff.
Exercise within the tropics creates some uncertainty for the launch from a meteorological perspective. On Saturday, June 22, the forty fifth Climate Squadron issued a launch climate forecast that implies simply 50 p.c odds of favorable launch climate on the opening of the launch window. That deteriorates to only 20 p.c by the shut of the window. Meteorologists are monitoring cumulus clouds, anvil clouds and lightning chance as major considerations.
“Deep tropical moisture will stay entrenched throughout the Florida peninsula into early subsequent week, and consequently, scattered to quite a few showers and thunderstorms may be anticipated every day, largely favoring the afternoon and night hours,” the forecast acknowledged.
“Whereas atmospheric stream will stay weak sufficient to permit each day seabreeze improvement, an incoming trough will possible end in delayed formation and westward development by Monday and Tuesday, with preliminary storm improvement nearer to the coast on these days.”
The 24-hour back-up launch alternative is usually the identical, however the opening of the launch window is 60 p.c favorable for liftoff.
The Falcon 9 first stage booster supporting this mission, B1078, will likely be launching for an eleventh time. It beforehand launched the astronauts and cosmonaut of the Crew-6 mission, the USSF-124 mission and 7 earlier Starlink flights.
Slightly greater than eight minutes after liftoff, B1078 will land on the SpaceX droneship, ‘A Shortfall of Gravitas.’ This would be the seventy fifth booster touchdown for ASOG and the 321st booster touchdown up to now.
Nevertheless, B1078 wasn’t all the time the supposed booster for this mission although. The unique flight plan had B1073 as the primary stage booster. Nevertheless, the booster was swapped out following a last-second scrub on June 14.
SpaceX hasn’t elaborated on the problem or points that triggered the scrub throughout engine ignition, however in a June 15 publish on X (previously Twitter), Kiko Dontchev, the vice chairman of Launch at SpaceX stated: “Powerful week coping with manufacturing challenges after which a uncommon scrub at engine startup yesterday on 10-2. “Sadly there’s a actual difficulty so we have to go examine the {hardware} intimately on this automobile… Painful, however security and reliability are the precedence.”
Listed below are moments main as much as engine ignition and the final word abort of the Starlink 10-2 in the meanwhile of T-0.

This would be the forty fifth launch of Starlink satellites to date in 2024 with one other deliberate for Sunday night, which is about to launch from Vandenberg House Drive Base at 8:45 p.m. PDT (11:45 p.m. EDT, 0345 UTC).
Starlink 10-2 will add one other 22 satellites to the rising megaconstellation. Following the launch, SpaceX could have launched 1,007 Starlink satellites this yr alone.
In accordance with knowledgeable orbital tracker and astronomer, Jonathan McDowell, there are greater than 6,000 lively Starlink satellites on orbit.
Falcon Heavy prepares to fly once more
Whereas SpaceX is making ready to launch a pair of Falcon 9 rockets on either side of the nation, in Florida, it’s additionally working with NASA and the Nationwide Oceanic Atmospheric Administration (NOAA) to launch a brand new climate satellite tv for pc on June 25 at 5:16 p.m. EDT (2116 UTC).
NASA’s Launch Companies Program (LSP) contracted SpaceX to launch the ultimate satellite tv for pc within the Geostationary Operational Environmental Satellites-R (GOES-R) sequence. NOAA describes these as “the Western Hemisphere’s most subtle weather-observing and environmental-monitoring system.”
In an interview with Spaceflight Now on Friday NASA’s launch director, Dr. Denton Gibson, stated the launch crew will likely be monitoring the climate over the subsequent few days.
“We now have some planning on doing or choices to make when it comes to after we roll the automobile out and earlier than we do all of our closing preps for launch,” Gibson stated.
He stated they’d make a willpower on whether or not a rollout of the Falcon Heavy rocket from the hangar to the pad would make extra sense on Sunday or Monday.
The Falcon Heavy has a backup launch date of June 26, but when it slips past that, Gibson stated there would should be discussions with the Japanese Vary earlier than a brand new date might be booked.
