Last-minute problems forced a launch delay Monday for SpaceX’s mega rocket Starship, attempting a comeback following an explosion on the last test flight.
The countdown got down to the 40-second mark, but it was halted because of issues with the 403-foot (123-meter) rocket, the world’s largest and most powerful.
Starship was supposed to blast off from the southern tip of Texas with four mock satellites on board for a space-skimming test flight. If the problems can be fixed quickly, another launch attempt could come Tuesday, according to SpaceX.
The last Starship demo ended in an explosion over the Atlantic in January, with flaming debris streaming over the Turks and Caicos.
Starship has already been booked by NASA for astronaut moon landings later this decade. SpaceX's Elon Musk intends to use the mammoth rockets to settle Mars.

Veteran Australia batter Usman Khawaja has announced he will retire from international cricket after the fifth Ashes test beginning Sunday at the Sydney Cricket Ground.
He didn't go quietly.
The Pakistan-born Khawaja, who was the first Muslim to play for Australia, used his retirement announcement Friday to criticize the “racial" stereotyping he experienced during his career.
It will be the 39-year-old Khawaja's 88th and final test — played at the ground where he began his first-class career. Khawaja scored his first Ashes century at the SCG with 171 against England in 2018.
It was also at that the SCG where he revived his career at age 35, scoring two centuries against England. That prompted one of the great late-career revivals, as Khawaja hit seven centuries in his next two years back in the side.
But Khawaja’s position had come under scrutiny and criticism this season after being unable to open in the first Ashes test in Perth due to back spasms and then missing the Brisbane test with the injury.
He was then initially left out in Adelaide until Steve Smith’s vertigo allowed Khawaja to return, before an 82 in the first innings there ensured he would stay in the side for the fourth test in Melbourne. Australia, with a 3-1 lead going into the fifth test, has retained the Ashes.
Khawaja said he felt he was treated “a little bit different, even to now,” because of his Pakistan and Muslim background.
"Different in the way I’ve been treated, different in how things have happened,” he said at a media conference in Sydney. “I had back spasms, it was something I couldn’t control. The way the media and the past players came out and attacked me . . . I copped it for about five days straight. Everyone was piling in.
“Once the racial stereotypes came in, of me being lazy, it was things I’ve dealt with my whole life. Pakistani, West Indian, colored players...we’re selfish, we only care about ourselves, we don’t care about the team, we don’t train hard enough."
Khawaja said he knew the end of his career was imminent.
“I guess moving into this series, I had an inkling this would be the last series," he said. "I’m glad I can go out on my own terms.”
Khawaja has scored 6,206 runs at an average of 43.49 in his 87 tests with 16 centuries and 28 half-centuries.
“Usman has made a huge contribution to Australian cricket both through his outstanding achievements as one of our most stylish and resilient batters . . . and off field, particularly through the Usman Khawaja Foundation,” Cricket Australia chief executive Todd Greenberg said in a statement.
“Usman has been one of Australia’s most reliable opening batters and testament to his success was him being named ICC test cricketer of the year the same season that Australia won the World Test Championship (in 2023).”
Khawaja said his No. 1 emotion on announcing his retirement was “contentment.”
“I’m very lucky to have played so many games for Australia the way I have,” Khawaja said. "I hope I have inspired people along the way.”
