SpaceX Aims for Stellar Reentry: Ensuring Safety of Starship Megarocket for a Successful Launch
SpaceX focuses on secure reentry of Starship Megarocket, maximizing safety for an explosive-free launch.
In the ambitious journey towards a fully reusable spacecraft capable of transporting humans and cargo to Earth orbit, the Moon, Mars, and beyond, SpaceX is gearing up for another critical test flight of its Starship rocket. The fourth fully integrated test flight (IFT-4) is slated for next week, pending regulatory approval, with a primary focus on demonstrating safe reentry and landing capabilities—if everything goes as planned.
Preparations and Milestones
SpaceX’s fourth test flight aims to achieve new milestones, potentially launching on the morning of Wednesday, June 5, from Texas. This follows the Federal Aviation Administration’s (FAA) completion of its safety investigation into the third flight, finding no public safety concerns. This clears the path for the FAA to issue the next launch license. Additionally, SpaceX completed its second wet dress rehearsal on May 23, using prototype stages Booster 11 and Ship 29, signifying readiness for the upcoming mission.
Lessons from Previous Flights
The third integrated flight test of Starship on March 14 marked significant progress. It featured a successful stage separation, a full-duration burn of the second-stage engines, an internal propellant-transfer demonstration for NASA, and a test of the Starlink dispenser door. Despite the upper stage disintegrating during reentry and the Super Heavy booster exploding 1,515 feet above the Gulf of Mexico due to engine shutdowns, the mission showed substantial improvements compared to the earlier tests, which both ended in premature explosions.
Goals of the Fourth Test
The IFT-4 mission shifts focus from achieving orbit to successfully returning both stages of the Starship. Primary objectives include executing a landing burn and soft splashdown of the Super Heavy booster in the Gulf of Mexico and achieving a controlled reentry of the Starship upper stage.
To enhance reliability, SpaceX has made several software and hardware upgrades. Changes include dropping the Super Heavy’s hot-stage adapter post-boostback burn to reduce weight for the final flight phase. This adapter allows the engines to remain ignited while the second stage separates and begins its burn. The upper stage is again targeting a splashdown in the Indian Ocean.
Key Aspects to Watch
Performance of the attitude control system will be crucial. In the third test, a filter blockage in this system caused a loss of control, resulting in unanticipated heating during reentry. SpaceX has since added more control redundancy and upgraded hardware to resist blockages. Observers will be keen to see how well the upper stage performs during its brief time in space and how its hexagonal heat-absorbing tiles fare during reentry.
A Step Towards a Reusable Future
SpaceX remains focused on rapidly developing the Starship to build a fully reusable transportation system. The company is keen to learn quickly from each test, continuously refining and improving its technology.
“The fourth flight of Starship will aim to bring us closer to the rapidly reusable future on the horizon,” SpaceX stated. “We’re continuing to rapidly develop Starship, putting flight hardware in a flight environment to learn as quickly as possible.”
As the world watches, the upcoming flight promises to provide stunning views of Earth and the Starship, along with insights into SpaceX’s progress. Each test flight brings its successes and challenges, and while the outcome remains uncertain, it’s certain to be an exciting and informative spectacle.

Astronaut Victor Glover is the latest in a long line of Black American explorers − including York, the enslaved man who played a key role in the Lewis and Clark expedition

Astronaut Victor Glover
In April 2026, four astronauts are scheduled to fly around the Moon. As part of NASA’s Artemis II mission, they will become the first humans to do so in half a century. One crew member, pilot Victor Glover, will become the first Black astronaut to ever orbit the Moon.
Glover’s achievement is worth celebrating. But it’s also worth remembering that he belongs to a long and underappreciated history. America’s first Black explorer didn’t fly an Apollo rocket or sail with the U.S. Exploring Expedition. He traveled with Lewis and Clark, and he was known by a single name: York.
I’m a historian who spent five years writing a book about Lewis and Clark, and I found new documents that show York was one of the most important people on their expedition. Even in a party that could number as many as 45 men, York stood out – for his courage, his skill and his sacrifices that helped the famous captains reach the Pacific Ocean.
York’s life as a slave
York was born in Virginia around 1770. Growing up, he was a creative and sociable child, unusually tall with dark hair and a dark complexion – “black as a bear,” a contemporary noted.
He was also enslaved by the Clarks. William Clark, who was around the same age, was also unusually tall, though his hair was a rusty red, and sometimes the boys played together. But the playing stopped once York turned 9 or 10. That’s when he joined the adult slaves in working full time. That’s also when he began to note the differences between his life and William’s – differences that became only clearer once William started ordering him around.
In the 1780s, the Clark household headed to Kentucky. York met a Black woman there and married her. He also became William’s “body servant.”
A body servant was a slave who stayed close to his owner and prioritized his comfort, laying out his clothes and serving his meals. When Meriwether Lewis asked Clark to join his expedition, in 1803, Clark ordered York to accompany him.
Perhaps York was excited for this adventure. Perhaps he was not – it would be punishing, and he would be separated from his wife.
Either way, York didn’t have a choice.
The Corps of Discovery
York proved his worth from the start. Once they reached St. Louis, the soldiers, later known as the Corps of Discovery, rushed to raise winter quarters. Working in hail and snow, York and the others built log huts. They needed rough planks for their tables and bunks, but the carpenters had only a single whipsaw to make them. They chose two men to operate this crucial tool. One of them was York.
On May 14, 1804, the corps began ascending the Missouri River. York helped row and tow the party’s barge, which was the size of a semi-truck trailer. He carried a rifle and hunted – according to the expedition’s journals, he was only the fifth named member to bring down a buffalo. York cooked for the captains. He collected scientific specimens. He nursed the sick, including several soldiers and, later on, Sacagawea, a Shoshone woman who would also prove essential to the expedition’s success.
The soldiers were not always kind in return. During this period, officers rarely brought along enslaved body servants. York’s race probably made some of the men angry or uncomfortable. One day, someone threw so much sand in his face that it nearly blinded him. Clark claimed it was “in fun,” but he also wrote that York was “very near losing his eyes,” and no one else got cruelly sprayed with sand.
That fall, during councils with Native leaders, York played a surprising and vital role. The Arikara, Mandan and Hidatsa all crowded in to see him and to touch his skin. They had never met a Black person before, and York showed off his strength and played with the Native children. Later, the Arikara said York was “the most marvelous” thing about the corps.
The next year, the expedition crossed the Rockies and the Continental Divide. York’s most important – and most overlooked – contributions came soon after. On the Columbia River and its tributaries, the party had to dig out five new canoes and then paddle them through treacherous rapids.
Lewis and Clark allowed only their best rivermen on these foaming, rock-riven waters. One of them was almost certainly York. During my research, I found an unpublished letter in which Clark praised York’s ability to “manage the boats.”
Just as important, York was a strong swimmer, a rare thing in an era when many people never learned to swim.
York’s life as an explorer
On the Columbia River, the corps survived a series of terrifying choke points – soggy hazards they referred to as the “Long Narrows” and the “Great Chute.” After that came the ocean. They had traveled together for more than 4,000 miles (6,400 kilometers), and when the captains asked the men to vote on where to put their final winter quarters, they made sure to ask York, too.
It was the latest sign that his role had changed during this epic journey. But those changes began with York. In the West, he found ways to make choices and assert himself. He sent a buffalo robe to his wife in Kentucky. When Clark told him to scale back his performances for Native people, York ignored him – because he wanted to, and because he could.
York’s vote was also evidence that, like Victor Glover today, he was an official American explorer, a key member of a sprawling, federally funded mission. From 1804 to 1806, the government devoted a larger percentage of its budget to the corps than it devotes to NASA today.
Part of that money was earmarked for York. The Army gave officers who brought along their slaves a monthly ration or its cash equivalent. When the corps made it home, the government paid US$274.57 for York’s labor, a sum similar to what the privates received. But that money didn’t go to York. It went to Clark.
The hidden history of Black explorers
There have been many Black explorers in American history. Thomas Jefferson launched other expeditions besides Lewis and Clark’s, and those expeditions also included enslaved people, though their names have not survived. Isaiah Brown served on the Wheeler Survey, which mapped the West in greater detail after the Civil War. Matthew Henson accompanied Robert Peary on his Arctic expeditions, which received some federal support. More recently, NASA has depended on Black astronauts such as Guy Bluford, Mae Jemison and Jeanette Epps, among others.
York and Victor Glover are, for now, the first and most recent examples of this inspiring tradition. But their contributions go beyond that. When the captains asked York to vote on the winter quarters, they were acknowledging in some small way that he’d proven he was more than a body servant.
Of course, York had always been more than that. It just took 4,000 miles for Lewis and Clark to see it.

🕒 [UPDATE] Artemis II Reaches the Moon
Orion has reached lunar proximity, giving astronauts a historic view of the Moon as the spacecraft performs its flyby maneuver.
Artemis II Successfully Launches
CAPE CANAVERAL, Fla. — NASA has successfully launched its Artemis II mission, marking the first crewed journey toward the Moon in more than 50 years.
The powerful Space Launch System (SLS) rocket lifted off from Kennedy Space Center on April 1, carrying four astronauts on a 10-day mission around the Moon and back.
On board are Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian astronaut Jeremy Hansen. The mission is already being hailed as a major milestone in NASA’s effort to return humans to deep space.
Shortly after liftoff, the Orion spacecraft successfully reached orbit and deployed its solar arrays, beginning its journey that will eventually send the crew on a translunar trajectory toward the Moon. 
Artemis II is a lunar flyby mission, meaning astronauts will not land but will travel farther from Earth than any human mission in decades while testing critical systems needed for future landings.
The mission also marks several historic firsts, including the first woman and the first person of color—Victor Glover—to travel into lunar space.
NASA says the mission is a key step toward future lunar landings and long-term plans to establish a human presence on the Moon later this decade.
🛰️ Artemis II Mission Timeline
The 10-day Artemis II mission follows a carefully planned trajectory from Earth to the Moon and back:
- Day 1: Launch and Earth orbit
