WASHINGTON —Elon Musk on Tuesday postponed by a few hours an expected update on SpaceX's plan to launch missions to Mars, saying it will take place after a Starship test flight scheduled for later in the day. He did not give a reason.
Musk, the world's richest person and a key supporter of U.S. President Donald Trump, has indicated he will be spending less time in government and on political campaigns in the future in order to focus on his business empire.
He had been scheduled to speak at 1 p.m. EDT (1700 GMT) from SpaceX's Starbase rocket facility in Texas. But at 1:06 p.m. EDT, Musk said on social media platform X that his talk was "postponed until after the Starship Flight 9 launch tonight," without elaborating.
Starship is scheduled to launch its ninth test flight Tuesday at 7:30 p.m. EDT (2330 GMT). It will be the rocket's first launch attempt after its last two launches exploded early in flight.
In his talk, Musk is expected to offer ambitious new timelines and road maps for sending SpaceX's Starship rocket system to Mars. The Red Planet, tens of millions of miles away from Earth, has been a long-sought but challenging destination for SpaceX, as well as U.S. government astronauts in recent years.
SpaceX has posted a placeholder for its livestream of the talk on platform X titled "The Road to Making Life Multiplanetary."
The speech could offer clues about the trajectory of NASA's cosmic strategy. While Musk has been known to make overly ambitious projections in past talks regarding SpaceX's development timelines, the billionaire has since amassed significantly more power and influence over the Trump administration's space agenda.
His Starship program has had difficulties lately. The rocket was grounded for nearly two months after a testing explosion in March over Caribbean islands, prompting the Federal Aviation Administration to expand its debris hazard zones.
The 400-foot-tall (122 m) Starship rocket system is the centerpiece of Musk's vision to ferry humans to Mars and expand SpaceX's global dominance in the satellite launch market, a foothold the company has gained with its reusable Falcon 9.
The rocket, picked by NASA in 2021 to land humans on the moon later this decade, is expected to play an even bigger role in the U.S. space program. Trump attended a Starship test launch in November and has publicly regaled Musk's Mars vision.
Musk and SpaceX remain influential over U.S. space policy despite the billionaire's shift away from government and signals to cut political spending.
Trump's choice to lead NASA, Jared Isaacman, a billionaire private astronaut and SpaceX customer for whom Musk advocated, testified before a U.S. Senate committee in April but has not advanced through the full confirmation process, while significant changes loom at the U.S. space agency.
A White House budget blueprint released earlier this month proposed $6 billion in cuts at NASA, bolstering the agency's Mars focus and threatening programs that Musk and Isaacman have criticized.
During a tense May 22 White House event with Trump and South African President Cyril Ramaphosa, South African-born Musk stood among Trump's cabinet officials in the room and was pointed out by the U.S. president.
"He actually came here on a different subject: sending rockets to Mars," Trump said. "He likes that subject better." —Reuters

Possible new dwarf planet spotted near the edge of the solar system
Cutout images of all 19 detections of the newly identified trans-Neptunian object named 2017 OF201 are seen, from the Canada France Hawaii Telescope (CFHT) and the Dark Energy Camera (DECam) on the 4-meter Victor M. Blanco Telescope, released by the Institute for Advanced Study in Princeton, New Jersey, on May 22, 2025. Jiaxuan Li and Sihao Cheng/Handout via REUTERS WASHINGTON - Scientists have identified an object about 435 miles (700 km) wide inhabiting the frigid outer reaches of our solar system that might qualify as a dwarf planet, spotting it as it travels on a highly elongated orbital path around the sun. The researchers called it one of the most distant visible objects in our solar system, and said its existence indicates that a vast expanse of space beyond the outermost planet Neptune and a region called the Kuiper Belt may not be deserted, as long thought. The Kuiper Belt is populated by numerous icy bodies. Given the name 2017 OF201, the object falls into a category called trans-Neptunian objects that orbit the sun at a distance beyond that of Neptune. The object takes about 25,000 years to complete a single orbit of the sun, compared to 365 days for Earth to do so. The researchers said 2017 OF201 was identified in observations by telescopes in Chile and Hawaii spanning seven years. "It is potentially large enough to qualify as a dwarf planet. Its orbit is very wide and eccentric, which means it experienced an interesting orbital migration path in the past," said astrophysicist Sihao Cheng of the Institute for Advanced Study in Princeton, New Jersey, who led the study with collaborators Jiaxuan Li and Eritas Yang, graduate students at Princeton University. Its size is estimated to be a bit smaller than Ceres, which is the smallest of the solar system's five recognized dwarf planets and has a diameter of about 590 miles (950 km). Pluto, the largest of those dwarf planets, has a diameter of about 1,477 miles (2,377 km). The mass of 2017 OF201 is estimated to be about 20,000 times smaller than Earth's and 50 times smaller than Pluto's. "We don't know the shape yet. Unfortunately it is too far away and it is a bit difficult to resolve it with telescopes," Cheng said. "Its composition is totally unknown yet, but likely similar to other icy bodies." The discovery was announced by the Minor Planet Center of the International Astronomical Union, an international organization of astronomers, and detailed in a study posted on the open-access research site arXiv. The study has not yet been peer reviewed. Earth's orbital distance from the sun is called an astronomical unit. 2017 OF201 is currently located at a distance of 90.5 astronomical units from the sun, meaning 90.5 times as far as Earth. But at its furthest point during its orbit, 2017 OF201 is more than 1,600 astronomical units from the sun, while the closest point on its orbit is about 45 astronomical units. That means it sometimes is closer to the sun than Pluto, whose orbital distance ranges from 30 to 49 astronomical units as it travels an elliptical path around the sun. The researchers suspect that the extreme orbit of 2017 OF201 may have been caused by a long-ago close encounter with the gravitational influence of a giant planet. "We still don't know much about the solar system far away because currently it is difficult to directly see things beyond about 150 astronomical units," Cheng said. "The presence of this single object suggests that there could be another hundred or so other objects with similar orbit and size. They are just too far away to be detectable right now." The five dwarf planets recognized by the International Astronomical Union are, in order of distance from the sun: Ceres, which is the largest object in the asteroid belt between Mars and Jupiter, then Pluto, Haumea, Makemake and Eris, which all orbit beyond Neptune. The organization defines a planet and a dwarf planet differently. A planet must orbit its host star - in our case the sun - and must be mostly round and sufficiently large that its gravitational strength clears away any other objects of similar size near its orbit. A dwarf planet must orbit the sun and be mostly round but it has not cleared its orbit of other objects. Cheng said the discovery of 2017 OF201 has implications for hypotheses involving the potential existence of a ninth planet in our solar system, dubbed Planet X or Planet Nine. This is because 2017 OF201's orbit does not follow the pattern exhibited by other known trans-Neptunian objects, which tend to cluster together. Some scientists had hypothesized that such clustering was caused by the gravity of a yet-to-be discovered planet. "The existence of 2017 OF201 as an outlier to such clustering could potentially challenge this hypothesis," Cheng said. — Reuters

Elon Musk leaving Trump administration
Elon Musk listens to US President Donald Trump speak in the Oval Office of the White House in Washington, D.C., February 11, 2025. REUTERS/ Kevin Lamarque Elon Musk is leaving the Trump administration after a tumultuous period working to restructure the federal government, a White House official confirmed. A White House official told Reuters it was accurate Musk is leaving the administration and his "off-boarding will begin tonight.' Musk on Wednesday thanked U.S. President Donald Trump as his time as a special government employee as a part of the Department of Government Efficiency draws to an end, he said in a post on social media platform X. Musk's 130-day mandate as a special government employee in the Trump administration was set to expire around May 30. The administration has said DOGE's efforts to restructure and shrink the federal government will continue. "The DOGE mission will only strengthen over time as it becomes a way of life throughout the government," Musk said. Trump and DOGE have managed to cut nearly 12%, or 260,000, of the 2.3 million-strong federal civilian workforce largely through threats of firings, buyouts and early retirement offers, a Reuters review of agency departures found. Musk on Tuesday criticized the price tag of Republicans' tax and budget legislation making its way through Congress. "I was disappointed to see the massive spending bill, frankly, which increases the budget deficit, not just decreases it, and undermines the work that the DOGE team is doing," Musk told CBS News. Musk's political activities have drawn protests and some investors have called for Musk to leave his work as Trump's adviser and manage Tesla more closely. Musk, the world's richest person, has defended his role as an unelected official who was granted unprecedented authority by Trump to dismantle parts of the U.S. government. —Reuters

China launches mission to retrieve asteroid samples
WASHINGTON —China on Wednesday embarked on its first mission to retrieve samples from a nearby asteroid with the nighttime launch of its Tianwen-2 spacecraft, a robotic probe that could make the fast-growing space power the third nation to fetch pristine asteroid rocks. China's Long March 3B rocket lifted off around 1:31 a.m. local time from the Xichang Satellite Launch Center carrying the Tianwen-2 spacecraft, which over the next year will approach the small near-Earth asteroid named 469219 Kamo?oalewa, some 10 million miles away. Chinese state media Xinhua confirmed the launch of Tianwen-2 and dubbed it a "complete success." Tianwen-2 is scheduled to arrive at the asteroid in July 2026 and shoot a capsule packed with rocks back to Earth for a landing in November 2027. The mission is the latest example of China's swiftly expanding space programs, a streak of cosmic achievements in recent years that includes landing robots on the far side of the moon, running its own national space station in orbit and investing heavily in plans to send humans to the lunar surface by 2030. Japan's Hayabusa that fetched samples from a small asteroid in 2010 marked the world's first such mission. Japan did it again in 2019 with its Ryugu mission, followed by the first U.S. asteroid retrieval mission, OSIRIS-REx, that brought back samples from the Bennu asteroid in 2020. Kamo?oalewa, the target asteroid for Tianwen-2, is known as a quasi-satellite of Earth, a close celestial neighbor that has orbited the sun for roughly a century, according to NASA. Its size is anywhere between 120 feet (40 meters) and 300 feet (100 meters).—Reuters
