Despite being surpassed by the recent beginnings of NASA's Space Launch System and SpaceX's Starship megarocket , the Falcon Heavy remains the world's most powerful operational commercial rocket , capable of carrying nearly metric tons (more than , pounds) of cargo to low Earth orbit, a few hundred kilometers high, if SpaceX expended all three boosters in the rocket's first stage.
Reserving a booster to recover the rocket's two side boosters reduces the Falcon Heavy's payload capacity, but SpaceX's heavy vehicle still outperforms any other rocket currently available to NASA . New rockets, such as United Lau Chinese Overseas Asia Number Data nch Alliance's (ULA) Vulcan and Blue Origin 's New Glenn , will approach the lift capacity of the Falcon Heavy, but both launchers are untested. ULA says it still has a chance to launch Vulcan's first test flight in December, and Blue Origin officials have said New Glenn could debut next year. These calendars could be generously described as optimistic.
Meanwhile, the Falcon Heavy is seven for seven since its maiden launch in February It has launched commercial communications satellites and military payloads . The launch of NASA's Psyche mission will mark the eighth flight of a Falcon Heavy rocket . If schedules hold, SpaceX could launch a ninth Falcon Heavy mission in late November with a Space Force-classified payload.

SpaceX often recovers the side boosters from its Falcon Heavy rockets for reuse. But this will not be possible on at least two of the upcoming Falcon Heavy launches for NASA.
As of Monday, SpaceX's Falcon rocket , which uses a single first-stage booster, has flown times this year. Now SpaceX is picking up pace with the launch of the larger Falcon Heavy, which combines three modified Falcon boosters into a single rocket .
"I have come to really appreciate what they have brought to the industry and they have continued to push the boundaries in different ways," Dunn stated of SpaceX. "I would expect them to say something like they've appreciated the commitment, the analytical and engineering rigor that NASA brings to the equation. I know, on the analytical side, in the software reviews , about some of the hardware issues we've had. "I've worked with them over the years, there have been many occasions where we reached a mutually acceptable solution to which both parties added value," he adds.
Earlier this year, NASA engineers formally certified the Falcon Heavy rocket to launch the agency's most expensive robotic missions, according to Dunn. This level of certification is known as Category in NASA parlance and requires a minimum of three successful flights of a common launch vehicle configuration, plus in-depth knowledge by NASA engineers of the design of a rocket and the launch contractor's quality control processes. If a launch company were to avoid this extensive government involvement, it would need to fly its launcher on consecutive successful missions.
NASA previously certified ULA's Delta IV and Atlas V rockets and SpaceX's Falcon at the Category level. ULA's Vulcan and Blue Origin's New Glenn launchers will need to successfully fly at least three times before being eligible for launch NASA's most critical scientific payloads. The Space Force and ULA agreed on a plan to certify Vulcan for national security duties after two successful missions.

In this presentation, a NASA Launch Services Program manager suggested that, on average, the third successful launch of a common launch vehicle configuration lags nearly three years behind a contractor's prediction, a year before the first flight of the rocket. That's where Blue Origin says it is now with New Glenn, while ULA's Vulcan rocket appears significantly closer to its first flight.
