Roman and Falcon Heavy standing on the launch pad
CAPE CANAVERAL, Fla — With less than 24 until launch, SpaceX has raised Falcon Heavy with NASA's Roman Space Telescope at Launch Complex-39A ahead of tomorrow's 7:26 a.m. EDT (1126 GMT).
Today, NASA will host a handful of press conferences and interviews leading up to the mission. At 9 a.m. EDT (1300 GMT), members of Romans' science team will provide a mission overview to discuss the telescope's instruments and discoveries ahead. A prelaunch press briefing will take place at 10:30 a.m. EDT (1430 GMT), which will provide the most up-to-date weather predictions for tomorrow's liftoff, as well as a status update on the rocket's progress in reaching the pad.
Both briefings will stream live on the Space.com homepage, as well as directly on NASA's website. Stay tuned for more updates as we track Roman's last day before launch!

Roman is go for launch!
NASA’s Nancy Grace Roman Space Telescope is officially "go" for launch! NASA made the announcement this afternoon (Aug. 28), after wrapping up the mission's Launch Readiness Review at Kennedy Space Center (KSC) in Florida.
SpaceX was part of that review, because Roman will lift off atop one of the company's Falcon Heavy rockets. Launch is scheduled to occur on Sunday (Aug. 30) at 7:26 a.m. EDT (1126 GMT) from KSC's Launch Complex-39A. You can watch it all live here at Space.com when the time comes.
T-2 days until Roman launches to space
It is now under 48 hours until the scheduled launch of NASA's Roman Space Telescope. Liftoff from Launch Complex-39A is planned for Sunday (Aug. 30) at 7:26 a.m. EDT (1126 GMT).
A SpaceX Falcon Heavy rocket will deliver Roman to Earth-Sun Lagrange point-2, a stationary sweet spot about 930,000 miles away that will keep the satellite in a persistant orbit on the side of Earth opposite the sun.
Weather Sunday morning is leaning toward favorable launch conditions, with a small chance of showers or thunderstorms during the 7 a.m. (1100 GMT) hour. Clouds and lightning will be the primary weather concerns, but conditions are expected to deteriorate more later in the day, giving Roman’s early-morning attempt a better shot of getting of the ground.
If weather conditions worsen or Sunday's launch is delayed, another window opens Monday (Aug. 31) at 7:22 a.m. EDT (1122 GMT).
SpaceX shows off Roman's Falcon Heavy rocket ride
SpaceX just gave us some good looks at the rocket that will carry NASA's Nancy Grace Roman Space Telescope to the final frontier this weekend.
That launcher is a Falcon Heavy, whose first stage consists of three modified, strapped-together Falcon 9 boosters. In an X post today (Aug. 26), SpaceX showed off that trio, which are currently in the hangar at Launch Pad 39A at NASA's Kennedy Space Center in Florida. The Falcon Heavy is scheduled to launch Roman — which will hunt for exoplanets and shed light on mysterious dark matter and dark energy — from Pad 39A on Sunday (Aug. 30) at 7:26 a.m. EDT (1126 GMT). You can watch the highly anticipated liftoff here at Space.com.
Roman arrives at SpaceX hangar before launch
Roman is one step closer to space! NASA transported the new space telescope inside its rocket fairing from the Kennedy Space Center's Payload Hazardous Servicing Facility to SpaceX's hanger at Launch Complex-39A (LC-39A).
The trip occurred overnight on Aug. 25, traveling in a caravan of vehicles to one its last Earthly destinations. Next, Roman and its protective fairings will be mated to SpaceX's Falcon Heavy rocket and undergo final fit checks and tests before rolling out to the launch pad.
A Launch Readiness Review panel will be held by NASA and SpaceX on Friday (Aug. 28), to make a final determination for launch readiness. If everything goes according to plan, liftoff will proceed toward the scheduled 7:26 a.m. EDT (1126 GMT) target on Sunday (Aug. 30).
SpaceX seals Roman inside Falcon Heavy fairing ahead of Aug. 30 launch
NASA's Nancy Grace Roman Space Telescope is one step closer to launch. SpaceX has sealed the bus-sized observatory inside the payload fairing of its Falcon Heavy rocket, the company announced today (Aug. 24). Everything remains on course for Roman to lift off from NASA's Kennedy Space Center in Florida early on Sunday morning (Aug. 30).
After launch, it'll take Roman about 30 days to reach its distant destination — the sun-Earth Lagrange Point 2, which lies about 930,000 miles (1.5 million kilometers) from Earth in the direction of Mars. After a roughly three-month checkout period, the scope will start observing the heavens — hunting for exoplanets and shedding light on dark matter and dark energy, among other tasks.
NASA's next great space telescope is almost ready to leave Earth.
Roman has spent the last several weeks undergoing its final launch preparations at KSC. Technicians loaded the observatory with 290 gallons (1,100 liters) of hydrazine fuel on July 25, then attached it to its payload adapter in early August.
Roman was recently encapsulated inside Falcon Heavy's payload fairing, and underwent a full launch-day dress rehearsal on Aug. 20. NASA, SpaceX and Roman mission managers then completed the mission's Flight Readiness Review on Aug. 21, formally clearing the observatory to begin its final launch preparations.
Next, the telescope, encapsulated in its payload fairings, will be transported to SpaceX's hangar at LC-39A, where it will be attached to Falcon Heavy rocket before the it rolls out to the pad for launch later this week.
