A private company launched another lunar lander on Wednesday, aiming to get closer to the moon’s south pole this time with a drone that would hop into a jet-black crater that never sees the sun.
Intuitive Machines’ lander, named Athena, caught a lift with SpaceX from NASA’s Kennedy Space Center. It is taking a fast track to the moon — with a landing on Thursday next week — while hoping to avoid the fate of its predecessor, which tipped over at touchdown.
Never before have so many spacecraft angled for the moon’s surface all at once. Last month, US and Japanese companies shared a rocket and separately launched landers toward Earth’s sidekick.

Texas-based Firefly Aerospace should get there first this weekend after a big head start.
The two US landers are carrying tens of millions of dollars of experiments for NASA as it prepares to return astronauts to the moon.
“It’s an amazing time. There’s so much energy,” NASA’s science mission chief Nicky Fox said a few hours ahead of the launch.
This is not Intuitive Machines’ first lunar rodeo. Last year, the Texas company made the first US touchdown on the moon in more than 50 years, but an instrument that gauges distance did not work and the lander came down too hard and broke a leg, tipping onto its side.
Intuitive Machines said it has fixed the issue and dozens of others. A sideways landing like last time would prevent the drone and a pair of rovers from moving out. NASA’s drill also needs an upright landing to pierce beneath the lunar surface to gather soil samples for analysis.
“Certainly, we will be better this time than we were last time, but you never know what could happen,” senior vice president of space systems Trent Martin said.
It is an extraordinarily elite club. Only five countries have pulled off a lunar landing over the decades: Russia, the US, China, India and Japan. The moon is littered with wreckage from many past failures.
The 4.7m Athena would target a landing 160km from the lunar south pole. Just 400m away is a permanently shadowed crater — the ultimate destination for the drone named Grace.
Named after the late computer programming pioneer Grace Hopper, the 1m drone would make three increasingly higher and longer test hops across the lunar surface using hydrazine fueled-thrusters for flight, and cameras and lasers for navigation.
If those excursions go well, it would hop into the nearby pitch-black crater, an estimated 20m deep.
Science instruments from Hungary and Germany would take measurements at the bottom while hunting for frozen water.
It would be the first up-close peek inside one of the many shadowed craters dotting both the north and south poles. Scientists suspect these craters are packed with ice. If so, this ice could be transformed by future explorers into water to drink, air to breathe and even rocket fuel.
NASA is paying US$62 million to Intuitive Machines to get its drill and other experiments to the moon. The company, in turn, sold space on the lander to others. It also opened up the Falcon rocket to ride-sharing.
They included NASA’s Lunar Trailblazer satellite, which would fly separately to the moon over the next several months before entering lunar orbit to map the distribution of water below.
PRECARIOUS RELATIONS: Commentators in Saudi Arabia accuse the UAE of growing too bold, backing forces at odds with Saudi interests in various conflicts A Saudi Arabian media campaign targeting the United Arab Emirates (UAE) has deepened the Gulf’s worst row in years, stoking fears of a damaging fall-out in the financial heart of the Middle East. Fiery accusations of rights abuses and betrayal have circulated for weeks in state-run and social media after a brief conflict in Yemen, where Saudi airstrikes quelled an offensive by UAE-backed separatists. The United Arab Emirates is “investing in chaos and supporting secessionists” from Libya to Yemen and the Horn of Africa, Saudi Arabia’s al-Ekhbariya TV charged in a report this week. Such invective has been unheard of
US President Donald Trump on Saturday warned Canada that if it concludes a trade deal with China, he would impose a 100 percent tariff on all goods coming over the border. Relations between the US and its northern neighbor have been rocky since Trump returned to the White House a year ago, with spats over trade and Canadian Prime Minister Mark Carney decrying a “rupture” in the US-led global order. During a visit to Beijing earlier this month, Carney hailed a “new strategic partnership” with China that resulted in a “preliminary, but landmark trade agreement” to reduce tariffs — but
Chinese President Xi Jinping’s (習近平) purge of his most senior general is driven by his effort to both secure “total control” of his military and root out corruption, US Ambassador to China David Perdue said told Bloomberg Television yesterday. The probe into Zhang Youxia (張又俠), Xi’s second-in-command, announced over the weekend, is a “major development,” Perdue said, citing the family connections the vice chair of China’s apex military commission has with Xi. Chinese authorities said Zhang was being investigated for suspected serious discipline and law violations, without disclosing further details. “I take him at his word that there’s a corruption effort under
China executed 11 people linked to Myanmar criminal gangs, including “key members” of telecom scam operations, state media reported yesterday, as Beijing toughens its response to the sprawling, transnational industry. Fraud compounds where scammers lure Internet users into fake romantic relationships and cryptocurrency investments have flourished across Southeast Asia, including in Myanmar. Initially largely targeting Chinese speakers, the criminal groups behind the compounds have expanded operations into multiple languages to steal from victims around the world. Those conducting the scams are sometimes willing con artists, and other times trafficked foreign nationals forced to work. In the past few years, Beijing has stepped up cooperation
