(CNN) — After a seven-month hiatus, SpaceX is set to launch a new, more powerful version its Starship megarocket — reigniting a make-or-break testing campaign aimed at hashing out unprecedented rocketry challenges and getting the vehicle ready to carry NASA astronauts to the moon.
But experts question whether this vehicle — or a competing spacecraft under development by the Jeff Bezos-founded Blue Origin — will be ready in time to sway the outcome of what US lawmakers say is an ongoing space race with China.
Liftoff, which is slated for Thursday at 6:30 p.m. ET, also comes during a period of mounting scrutiny around SpaceX. The company is headed for a record-shattering initial public offering, and explosive, attention-grabbing mishaps, such as the kind that have resulted from previous Starship test flights, tend to make investors squeamish.
There “are likely more eyes on this test launch than ever before for this company,” noted Andrew Chanin, the CEO of the investment firm ProcureAM. It’s “a risky call to do this highly anticipated launch so close to the IPO.” But, he added, “Fortune favors the bold.”
With SpaceX planning for Starship to play a central role in the future of its space-based internet business, Starlink, as well as offering services to NASA and the US military, there’s a lot riding on the megarocket’s eventual success.
And it’s not yet clear whether Starship will work.
Starship’s explosive record
SpaceX notched some crucial early successes with Starship during uncrewed, suborbital test flights. The company was first able to recover the Super Heavy booster, for example, in October 2024 — landing the rocket snugly in the metal arms of SpaceX’s “Mechazilla” launch tower in Starbase, Texas.
But the company faced several setbacks with Version 2 of Starship, which first took flight in January 2025.
During two separate test flights in January and March, the vehicle exploded near populated areas east of Florida, creating debris that hit roadways in Turks and Caicos and washed up onto Bahamian islands.
On another test flight in May 2025, the launch system performed notably better, but the Starship spacecraft ultimately spun out of control as it descended toward its landing site in the Indian Ocean. Even the Super Heavy booster, which was meant to make a controlled splashdown in the Gulf, exploded upon landing early in the mission.
Following those three incidents — each of which triggered investigations overseen by federal regulators — SpaceX hit another snag when a Starship spacecraft exploded during a ground test last June. The mishap, which occurred as SpaceX was conducting ground tests of the rocket, spurred an emergency response from nearby authorities in Brownsville, Texas.
An incident report, obtained by CNN via a freedom of information act request, described a tense scene.
“Dispatchers were forced into rapid-fire triage, making split-second decisions to prioritize life-threatening emergencies,” the report reads. “At the same time, public panic rippled across the region, and command staff had to rapidly reallocate emergency resources across the city.”
Local officials did not respond to a request for comment about how emergency response preparedness in the area may have changed since the incident.
SpaceX experienced yet another explosive issue during ground testing in November, when the company was aiming to conduct a fueling test of a Starship V3 rocket. The vehicle was destroyed, but “the test site incurred very little damage and of course no
