There remains a 50 percent chance of acceptable weather at Cape Canaveral on Monday morning for launch of a SpaceX Falcon 9 rocket with 60 Starlink Internet satellites.

The prime weather concerns at Cape Canaveral are with disturbed weather and thick clouds, but upper level winds -- which are not counted in the 50 percent probability of violation -- are also forecast to be very strong Monday, according to the 45th Weather Squadron at Patrick Air Force Base.

Liftoff is scheduled for 9:49 a.m. EST (1449 GMT), and the launch window Monday is effectively instantaneous.

"A low pressure system over the Gulf of Mexico is spreading unsettled weather and cloudiness across the Gulf Coast states and into the Florida Panhandle," forecasters wrote in an updated outlook today. "This cloudiness will spread across Central Florida overnight, with light rain also possible. The main concerns during the launch window will be disturbed weather and thick clouds."

Maximum upper level winds will be around 135 knots from the west at about 35,000 feet, according to weather forecasters.

Weather balloons sent aloft during Monday morning's countdown will collect data on the actual winds at high altitude. That data will be fed to SpaceX to determine whether the winds are actually acceptable for launch of the Falcon 9 rocket.

Forecasters expect isolated rain showers in the area Monday morning, with broken clouds at 3,000 feet and 8,000 feet, and an overcast cloud deck at 25,000 feet. Winds should be light and variable, with a temperature of about 57 degrees Fahrenheit at launch time.

If the launch is delayed to Tuesday, better weather is predicted, with an 80 percent chance of favorable conditions and lighter upper level winds.

Timeline for Falcon 9 launch of Starlink satellites
January 27, 2020 | Stephen Clark

Follow the key events of the Falcon 9 rocket's ascent to orbit with 60 satellites for SpaceX's Starlink broadband network.

The 229-foot-tall (70-meter) rocket is scheduled to lift off Monday at 9:49 a.m. EST (1449 GMT) from the Complex 40 launch pad at Cape Canaveral Air Force Station in Florida.

The Falcon 9 will head northeast from Cape Canaveral over the Atlantic Ocean to place the 60 Starlink satellites into a circular orbit around 180 miles (290 kilometers) above Earth. The satellites will use their ion thrusters to maneuver into their higher orbit for testing, before finally proceeding to an operational orbit at an altitude of approximately 341 miles (550 kilometers).

The Falcon 9's first stage will target a landing on SpaceX's drone ship "Of Course I Still Love You" in the Atlantic Ocean nearly 400 miles northeast of Cape Canaveral.

The first stage booster launching tonight previously flew on two missions. The booster first launched from the Kennedy Space Center in March 2019 with SpaceX's first unpiloted Crew Dragon capsule, then launched again in June 2019 from Vandenberg Air Force Base in California with the Canadian Radarsat Sonstellation Mission.

For Monday's mission, SpaceX will also attempt to catch both halves of the Falcon 9's payload fairing using nets aboard the ocean-going ships "Ms. Tree" and "Ms. Chief" in the Atlantic Ocean.

Data source: SpaceX

T-0:00:00: Liftoff


After the rocket's nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from pad 40.

T+0:01:13: Max Q


The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure, a few seconds after surpassing the speed of sound.

T+0:02:33: MECO


The Falcon 9's nine Merlin 1D engines shut down.

T+0:02:36: Stage 1 Separation


The Falcon 9's first stage separates from the second stage moments after MECO.

T+0:02:43: Stage 2 Ignition


The second stage Merlin 1D vacuum engine ignites for an approximately six-and-a-half-minute burn to inject the Starlink satellites into a parking orbit.

T+0:03:24: Fairing Jettison


The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core.

T+0:06:41: Stage 1 Entry Burn Complete


A subset of the first stage's Merlin 1D engines completes an entry burn to slow down for landing. A final landing burn will occur just before touchdown on SpaceX's drone ship "Of Course I Still Love You" around 385 miles (620 kilometers) northeast of Cape Canaveral.

T+0:08:24: Stage 1 Landing


The Falcon 9 rocket's first stage booster touches down on SpaceX's drone ship in the Atlantic Ocean.

T+0:08:49: SECO 1


The Merlin 1D vacuum engine turns off after placing the Starlink satellites in a temporary parking orbit, beginning a 36-minute coast in space.

T+0:45:55: Stage 2 Restart


The Falcon 9's second stage engine ignites again for a 2-second burn to circularize its orbit.

T+0:45:57: SECO 2


The Merlin 1D vacuum engine shuts down after reaching a target orbit about 180 miles (290 kilometers) high with an inclination of approximately 53 degrees.

T+1:01:48: Starlink Deployment


The 60 flat-panel Starlink satellites, each with a mass of about 573 pounds (260 kilograms) deploy from the Falcon 9 rocket's second stage.

T-minus 3 hours. SpaceX's launch team will soon complete checkouts of the rocket ahead of the start of fueling of the Falcon 9 with super-chilled, densified RP-1 kerosene and liquid oxygen propellants.

SpaceX's launch conductor will verify all members of the launch team are ready to proceed with the final 35-minute automated countdown sequence at 9:11 a.m. EST (1411 GMT), followed by the start of filling the rocket with super-chilled, densified RP-1 kerosene and liquid oxygen propellants at 9:14 a.m. EST (1414 GMT).

Liquid oxygen loading into the second stage will begin at T-minus 16 minutes, at 9:33 a.m. EST (1433 GMT), followed by final chilldown of the rocket's nine Merlin first stage engines, a final pre-flight engine steering check, switching of the rocket to internal power, and pressurization of the Falcon 9's propellant tanks leading up to liftoff.

T-minus 3 hours. SpaceX's launch team is completing checkouts and final preparations on the Falcon 9 rocket before the start of fueling at Cape Canaveral this morning.

Liftoff is set for 9:49am EST (1449 GMT), but weather conditions remain a concern.

Good morning from the Kennedy Space Center. A few miles away, SpaceX's Falcon 9 rocket stands vertical ahead of a scheduled liftoff at 9:49 a.m. EST (1449 GMT) with SpaceX's next batch of 60 Starlink Internet satellites.

Skies over Florida's Space Coast are overcast this morning, and one of the concerns for launch today is thick cloud conditions. Upper level winds are also being monitored closely by SpaceX, and weather teams at Cape Canaveral are regularly sending up weather balloons throughout the countdown to measure wind speeds at various altitudes.

T-minus 2 hours. SpaceX intends to recover the first stage after today's launch. The company's drone ship "Of Course I Still Love You" is parked roughly 400 miles (640 kilometers) northeast of Cape Canaveral.



The Falcon 9's first stage booster will target a propulsive landing on the football field-sized drone ship at T+plus 8 minutes, 24 seconds.

SpaceX's two fairing recovery ships -- named "Ms. Tree" and "Ms. Chief" -- are also in position in the Atlantic Ocean to try and catch the two halves of the Falcon 9's payload shroud.

The vessels are equipped with giant nets to catch the fairing shells as they descend under parafoils. SpaceX has reused the fairing after retrieving the hardware from the sea, but catching them in the nets prevents the shells from being drenched in salt water. That eases their refurbishment and reuse, SpaceX says.

Upper level winds over Florida's Space Coast this morning are as strong as predicted. Peak winds are around 138 knots from the west between 35,000 and 40,000 feet.

SpaceX will analyze the wind data to determine if it's safe for the Falcon 9 to launch.
