SpaceX is gearing up for another launch attempt on Monday night to deploy 23 additional satellites for its Starlink internet service from Cape Canaveral. The Falcon 9 rocket is scheduled to liftoff from pad 40 at 7:20 p.m. EDT (2320 UTC).

On Sunday night, the launch countdown was halted at T-30 seconds due to a detected issue with the system responsible for separating the rocket's first and second stages. As a result, the launch was rescheduled for Monday.

According to the forecast by the 45th Weather Squadron at Cape Canaveral, there is a 95-percent chance of favorable conditions for the Falcon 9 launch, with the only concern being cumulus clouds that may trigger lightning.

In case of any delays or further issues, SpaceX has seven backup launch opportunities throughout Monday night. The final backup slot is scheduled for 10:22 p.m. EDT (0222 UTC).

Once lifted off from Space Launch Complex 40 (SLC-40), the Falcon 9 rocket will maneuver onto a south-easterly trajectory towards an orbit inclined at 43 degrees to the equator. Notably, the first-stage booster, with its eighth flight, is expected to land on the drone ship named 'Of Course I Still Love You' approximately eight and a half minutes after launch. Identified as tail number B1077, this booster has already played a crucial role in multiple missions, including Crew 5 to the International Space Station.

Approximately 1 hour, 5 minutes, and 38 seconds after launch, the 23 Starlink satellites will be deployed into a 182×177 mile (293×285 km) orbit.

With the successful deployment of Sunday's 22 Starlink satellites from Vandenberg Space Force Base in California, SpaceX now has nearly 4,988 Starlink satellites orbiting the Earth, as per statistics compiled by Jonathan McDowell. Should all go as planned with Monday's launch from the East Coast, SpaceX will surpass the 5,000-satellite mark for its Starlink constellation.

Moreover, this upcoming launch marks SpaceX's 90th orbital mission within the last 365 days, showcasing a remarkable launch frequency of approximately one mission every four days. Company officials have expressed their ambition to further accelerate the pace of launches, aiming for 100 flights in 2023, and a total of 144 missions by 2024.

Spaceflight Now will provide live coverage from Cape Canaveral, commencing approximately one hour before liftoff.
