The first time, it tumbled out of control and exploded; the second time, an onboard fire triggered its self-destruct mechanism.

On Thursday, SpaceX will once again attempt to fly its giant rocket, Starship. The company’s founder, Elon Musk, had said that he had hoped for a launch attempt towards the end of the week. A final approval from the Federal Aviation Administration came through late Wednesday afternoon.

The company has made upgrades and likely changed procedures since its previous attempts, but it remains to be seen whether this will be the launch that proves that the largest rocket ever built can really fly.

“They say that the third time is a charm,” says Paulo Lozano, director of the space propulsion laboratory at MIT. But, he adds, launching a rocket as large as Starship “is not a simple task.”

“Nobody has done like this before at this scale,” he says.

Starship is a stainless steel monster. It stands nearly 400 feet tall, and its first stage, known as “Super Heavy,” is powered by 33 Raptor engines that must all work together to heave it towards orbit.

SpaceX founder Elon Musk believes this massive machine can carry humans to the moon and Mars. Its durable stainless steel construction makes it easy to reuse, at least in theory, and could dramatically reduce the cost of launching satellites and people into orbit. NASA has given billions to SpaceX to develop Starship as a lunar landing system that could deliver astronauts to the lunar surface.

But before Starship can fulfill these lofty ambitions, it’s got to fly. In its first test, nearly a year ago, the spacecraft made it off the ground, but it did considerable damage to the launch pad in the process, hurling concrete and debris for up to half-a-mile. Multiple engines in the first stage gave out, and as the rocket fell back to Earth, its self-destruct system also failed to properly destroy it. It tumbled out of control for several seconds before finally breaking apart.

The second flight in December was more successful. The launch pad was not obliterated by the 33 engines, all of which fired as expected. The Starship also successfully separated from its booster at the predetermined altitude. But the booster failed to reignite its engines properly and exploded before it could descend back to the Gulf of Mexico. Starship’s self-destruct system (beefed up after the first flight) also detonated before it could reach its desired altitude.

Scott Manley, a popular YouTuber who closely tracks Starship launches, says that the second stage likely failed because it had too much fuel and oxidizer aboard. To try and reduce mass as it flew into space, “it began dumping excess oxygen,” he says. Unfortunately, the oxygen, which is highly flammable, apparently caught fire either in or around the rear of the rocket. “There was a fire in there that got turbo-charged by having oxygen just leak all over it,” he says.

This time around, Manley says several additional changes have been made. Based on photos taken by rocket-watchers near the site, the fire suppression system appears to have been beefed up and the oxygen-dumping system has also been tweaked. “That will probably solve that problem,” he says, but adds, “It doesn’t guarantee they’ve solved every single problem.”

Starship has also added additional tasks to the flight test. It will attempt to briefly open its payload bay doors while in orbit. And it will conduct a test to see whether it can transfer propellant from one fuel tank to another. Moving fuel around will be critical for both lunar and Martian trips, as the vehicle will need to top off its tanks for both journeys.

Lozano says that fuel transfer is particularly challenging in space.

“All of these propellants have very high vapor pressure,” he says. That means if they’re exposed to the vacuum of space, they will “decompress explosively.” Even the act of pumping fuel is tricky in zero gravity, Lozano, says, because there’s no force pressing the fuel towards the bottom of the tanks, where pumps might normally operate.

“There is no experience doing this kind of thing,” he says. “It’s a new technology, but I’m pretty sure that technically it’s possible to do.”

Finally, Starship will also attempt to relight its Raptor engines before re-entering Earth’s atmosphere. Both Manley and Lozano say they will be closely watching that process.

As Starship enters the atmosphere, “you need to protect it from massive amounts of heating,” Manley says. The underbelly of the ship is covered in thermal protection tiles, he says, but “they’ve been falling off on every single test. So it remains to be seen whether they can actually keep enough tiles on Starship for it to make it through re-entry.”

“If it comes back in one piece, I think it’s going to be a big success,” Lozano says.

In total, the flight test will take a little over an hour, and — assuming all goes well — the spaceship will splash down in the Indian Ocean.

Launch is expected to take place Thursday around 8 a.m. Eastern.

Map: 4.9-Magnitude Earthquake Shakes Louisiana

Note: Map shows the area with a shake intensity of 4 or greater, which U.S.G.S. defines as “light,” though the earthquake may be felt outside the areas shown.  All times on the map are Central time. The New York Times

A light, 4.9-magnitude earthquake struck in Louisiana on Thursday, according to the United States Geological Survey.

The temblor happened at 5:30 a.m. Central time about 6 miles west of Edgefield, La., data from the agency shows.

U.S.G.S. data earlier reported that the magnitude was 4.4.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Man accused of plot to assassinate Trump testifies Iran pressured him, says Biden and Haley were other possible targets

Man accused of plot to assassinate Trump testifies Iran pressured him, says Biden and Haley were other possible targets

The allegation sounded like the stuff of spy movies: A Pakistani businessman trying to hire hit men, even handing them $5,000 in cash, to kill a U.S. politician on behalf of Iran ‘s powerful paramilitary Revolutionary Guard.

It was true, and potential targets of the 2024 scheme included now-President Donald Trump, then-President Joe Biden and former presidential candidate and ex-U.N. Ambassador Nikki Haley, the man told jurors at his attempted terrorism trial in New York on Wednesday. But he insisted his actions were driven by fear for loved ones in Iran, and he figured he’d be apprehended before anything came of the scheme.

“My family was under threat, and I had to do this,” the defendant, Asif Merchant, testified through an Urdu interpreter. “I was not wanting to do this so willingly.”

Merchant said he had anticipated getting arrested before anyone was killed, intended to cooperate with the U.S. government and had hoped that would help him get a green card.

U.S. authorities were, indeed, on to him – the supposed hit men he paid were actually undercover FBI agents – and he was arrested on July 12, 2024, a day before an unrelated attempt on Trump’s life in Butler, Pennsylvania.  During a search, investigators said they found a handwritten note that contained the codewords for the various aspects of the plot, CBS News previously reported

Merchant did sit for voluntary FBI interviews, but he ultimately ended up with a trial, not a cooperation deal.

“You traveled to the United States for the purpose of hiring Mafia members to kill a politician, correct?” Assistant U.S. Attorney Nina Gupta asked during her turn questioning Merchant Wednesday in a Brooklyn federal court.

“That’s right,” Merchant replied, his demeanor as matter-of-fact as his testimony was unusual.

The trial is unfolding amid the less than week-old Iran war, which killed Iranian Supreme Leader Ayatollah Ali Khamenei in a strike that Trump summed up as “I got him before he got me.” Jurors are instructed to ignore news pertaining to the case.

The Iranian government has denied plotting to kill Trump or other U.S. officials.

Merchant, 47, had a roughly 20-year banking career in Pakistan before getting involved in an array of businesses: clothing, car sales, banana exports, insulation imports. He openly has two families, one in Pakistan and the other in Iran – where, he said, he was introduced around the end of 2022 to a Revolutionary Guard intelligence operative. They initially spoke about getting involved in a hawala, an informal money transfer system, Merchant said.

Merchant testified that his periodic visits to the U.S. for his garment business piqued the interest of his Revolutionary Guard contact, who trained him on countersurveillance techniques.

The U.S. deems the Revolutionary Guard a “foreign terrorist organization.” Formally called the Islamic Revolutionary Guard Corps, the force has been prominent in Iran under Khamenei.

Merchant said the handler told him to seek U.S. residents interested in working for Iran. Then came another assignment: Look for a criminal to arrange protests, steal things, do some money laundering, “and maybe have somebody murdered,” Merchant recalled.

“He did not tell me exactly who it is, but he told me – he named three people: Donald Trump, Joe Biden and Nikki Haley,” he added.

In 2024, multiple sources familiar with the investigation told CBS News Merchant planned to assassinate current and former government officials across the political spectrum.

Merchant allegedly sketched out the plot on a napkin inside his New York hotel room, prosecutors said, and told the individual “that there would be ‘security all around’ the person” they were planning to kill.

“No other option”

After U.S. immigration agents pulled Merchant aside at the Houston airport in April 2024, searched his possessions and asked about his travels to Iran, he concluded that he was under surveillance. But still he researched Trump rally locations, sketched out a plot for a shooting at a political rally, lined up the supposed hit men and scrambled together $5,000 from a cousin to pay them a “token of appreciation.”

He even reported back to his Revolutionary Guard contact, sending observations – fake, Merchant said – tucked into a book that he shipped to Iran through a series of intermediaries.

Merchant said he “had no other option” than to play along because the handler had indicated that he knew who Merchant’s Iranian relatives were and where they lived.

In a court filing this week, prosecutors noted that Merchant didn’t seek out law enforcement to help with his purported predicament before he was arrested. He testified that he couldn’t turn to authorities because his handler had people watching him.

Prosecutors also said that in his FBI interviews, Merchant “neglected to mention any facts that could have supported” an argument that he acted under duress.

Merchant told jurors Wednesday that he didn’t think agents would believe his story, because their questions suggested “they think that I’m some type of super-spy.”

“And are you a super-spy?” defense lawyer Avraham Moskowitz asked.

“No,” Merchant said. “Absolutely not.”
