Citing debris risk, NASA delays spacewalk to fix space station antenna

Published

A spacewalk planned for Tuesday to repair a faulty antenna on the International Space Station was postponed indefinitely, NASA said, citing a “debris notification” it received for the orbiting research laboratory.

Two U.S. astronauts had been scheduled to venture outside the space station at 7:10 a.m. Eastern time (1210 GMT) to begin their work, facing what NASA officials had called a slightly elevated risk posed by debris from a Russian anti-satellite missile test this month.

But about five hours before the outing was to have commenced, NASA said on Twitter that the spacewalk had been called off for the time being.

“NASA received a debris notification for the space station. Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the Nov. 30 spacewalk until more information is available,” the space agency tweeted.

It was not made clear how close debris had come to the space station, orbiting about 250 miles (402 km) above the Earth, or whether it was related to the Russian missile test.

NASA TV had planned to provide live coverage of the 6-1/2-hour “extravehicular activity,” or EVA, operation by astronauts Thomas Marshburn and Kayla Brown. The outing would be the fifth spacewalk for Marshburn, 61, a medical doctor and former flight surgeon with two previous trips to orbit, and the first for Barron, 34, a U.S. Navy submarine officer and nuclear engineer on her debut spaceflight for NASA.

The objective is to remove a faulty S-band radio communications antenna assembly, now more than 20 years old, and replace it with a new spare stowed outside the space station.

According to plans, Marshburn was to have worked with Barron while positioned at the end of a robotic arm operated from inside the station by German astronaut Matthias Maurer of the European Space Agency, with help from NASA crewmate Raja Chari.

The four arrived at the space station on Nov. 11 in a SpaceX Crew Dragon capsule launched from the Kennedy Space Center in Cape Canaveral, Florida, joining two Russian cosmonauts and a NASA astronaut already aboard the orbiting outpost.

Four days later, an anti-satellite missile test conducted without warning by Russia generated a debris field in low-Earth orbit, and all seven crew members took shelter in their docked spaceships to allow for a quick getaway until the immediate danger passed, according to NASA.

The residual debris cloud from the blasted satellite has dispersed since then, according to Dana Weigel, NASA deputy manager of the International Space Station (ISS) program.

But NASA calculates that the remaining fragments continued to pose a “slightly elevated” background risk to the space station as a whole, and a 7% higher risk of spacewalkers’ suits being punctured, as compared to before Russia’s missile test, Weigel told reporters on Monday.

Although NASA has yet to fully quantify additional hazards posed by more than 1,700 larger fragments it is tracking around the station’s orbit, the 7% higher risk to spacewalkers falls “well within” fluctuations were previously seen in “the natural environment,” Weigel said.

Still, mission managers canceled several smaller maintenance tasks under consideration for Tuesday’s spacewalk, Weigel added.

NASA set for first crewed moon return in over half a century

Published

on

NASA is preparing to launch the first crew of astronauts toward the moon in over 53 years with its second Artemis mission, a key ​test flight in humanity’s broader lunar goals as the U.S. races to reassert leadership in space faced with growing competition from China.

Three U.S. and one Canadian astronaut are due for ‌liftoff aboard NASA’s Orion capsule and Space Launch System rocket on Wednesday for a 10-day test mission swinging around the moon and back, a winding journey taking them deeper into space than humans have ever gone before, Reuters reported.

The mission is the first crewed test flight in NASA’s Artemis program, the flagship U.S. effort to begin regular flights to the moon, at an estimated cost of at least $93 billion since 2012. Not since Apollo 17 in 1972 have humans touched down on the moon’s surface, a ​tricky feat NASA aims to repeat in 2028 at the rugged lunar south pole.

The U.S. is the only country to have put humans on another celestial body with its six lunar landings ​of the Apollo program, driven by competition with the former Soviet Union.

China, a formidable technological rival to the U.S., has made steady progress in its own moon ⁠program in recent years, with a string of robotic lunar landings and a 2030 goal to put its own crew on the surface. U.S. officials have focused on beating China to the surface.

ANSWERING ‘THE QUESTION OF OUR ​LIFETIME’

NASA astronaut Christina Koch, Artemis II mission specialist, on Sunday said the moon is a “witness plate” to the solar system’s formation, and a stepping stone to Mars, “where we might have the most likelihood of finding evidence ​of past life.”

“Many, many countries have recognized the value that there is in exploring further into the solar system, to the moon and on to Mars,” she told reporters. “They recognize that not only can we gain all these extremely tangible benefits, but that we have the opportunity to answer the question that could be the question of our lifetime, which is, are we alone?”

“Answering that question starts at the moon,” she said. “The question is not should we go, but should we lead, or ​should we follow?”

Through a series of increasingly advanced Artemis missions extending into the next decade, the U.S. aims to set precedent for how others will operate and coexist on the moon’s surface, where someday countries and ​companies can exploit rocky lunar resources and practice for much more difficult missions to Mars.

COMMERCIAL LUNAR MARKET

NASA is relying on an array of companies in its moon program with the hope of stimulating a commercial lunar market in the ‌future, the value ⁠of which is hard to estimate, analysts say.

A PricewaterhouseCoopers report from January estimates $127 billion in revenues by 2050 from lunar surface activities, with investments potentially reaching $72 billion to $88 billion through the same period.

But for now, and in the near future, governments will drive companies’ lunar strategies and revenue. It will be a long time before commercial growth exists on the moon independently of government funding, said Akhil Rao, an economist at analysis firm Rational Futures who was a research economist at NASA.

“NASA did not see a short-run economic value that companies would be able to derive that would allow NASA to be hands-off,” said Rao, who was among a team ​of economists and space policy staff laid off last ​year amid the Trump administration’s sweeping federal workforce ⁠cuts.

The Artemis II mission will pose a greater test of NASA’s Orion capsule and SLS, which conducted a similar mission without crew in 2022. The astronauts on board will test critical life-support systems, crew interfaces, navigation and communications before NASA proceeds with more complex missions in the following years.

Liftoff is scheduled for April 1, though ​it could happen any day after until April 6, depending on weather conditions in Florida and any last-minute snags with the rocket. Thereafter, another launch ​window, determined largely by the ⁠orbital mechanics between Earth and the moon, opens on April 30.

Artemis III, the next mission planned for 2027, will involve the Orion capsule docking in Earth’s orbit with NASA’s two lunar landers – the Blue Moon system from Jeff Bezos’ Blue Origin and Starship from Elon Musk’s SpaceX. The delicate tag-up will demonstrate how the landers will pick up astronauts before heading for the moon’s surface.

That mission was added to the program in February by NASA’s new administrator, Jared ⁠Isaacman, a billionaire ​private astronaut who has more broadly shaken up the program with new objectives. His decision pushed the program’s first crewed lunar landing to ​Artemis IV.

The architecture is more complex than the Apollo missions, involving an array of companies funded by NASA with the hope of stimulating private competition and market activity around the moon. Boeing and Northrop Grumman lead SLS and Lockheed Martin builds Orion for NASA.

SpaceX ​and Blue Origin are developing their own landers with NASA funding but under different types of contracts that allow them to offer the spacecraft to other customers.

Trump administration set to receive $10 billion fee for brokering TikTok deal, WSJ reports

Vice President JD Vance had in ​September said that the new U.S. company will be valued at around $14 billion.

Published

President Donald Trump’s administration is set to receive a roughly $10 billion fee from investors in the recently completed ​deal to take control of TikTok’s U.S. business, the Wall Street ‌Journal reported on Friday, citing people familiar with the matter.

TikTok’s Chinese owner, ByteDance, in January finalized a deal to establish a majority American-owned joint venture that will secure U.S. ​data, to avoid a U.S. ban on the short video app ​used by over 200 million Americans.

TikTok USDS Joint Venture LLC will ⁠secure U.S. user data, apps and algorithms through data privacy and cybersecurity ​measures. It disclosed few details about the divestiture.

Vice President JD Vance had in ​September said that the new U.S. company will be valued at around $14 billion.

The payment is part of the agreement through which investors friendly with the administration gained control of TikTok’s ​U.S. operations from ByteDance, WSJ said. It is on top of the ​investments already made to establish a new entity to operate the app in the U.S.

Investors ‌Oracle (ORCL.N), ⁠Silver Lake, Abu Dhabi’s MGX and other backers paid about $2.5 billion to the Treasury Department when the deal closed and are to make a number of subsequent payments until the total reaches $10 billion, per the Journal.

TikTok and ​the White House did ​not immediately respond ⁠to Reuters requests for comment.

Officials from the administration have said the fee is justified, citing Trump’s role in rescuing ​TikTok’s U.S. operations and guiding negotiations with China to ​complete the ⁠deal while tackling lawmakers’ concerns over national security, according to WSJ.

Earlier this month, Trump and U.S. Attorney General Pam Bondi were sued by retail investors in two ⁠social ​media rivals of TikTok seeking to reverse the ​U.S. president’s approval of a deal by the company’s Chinese owner ByteDance to form a majority ​American-owned joint venture.

NASA eyes March 6 launch of astronaut moon mission 

Artemis program managers completed a comprehensive simulation of the Space Launch System’s launch-day countdown, but said remaining work could still push the launch date further into March.

NASA officials said the agency was targeting March 6 for the launch of four astronauts around the moon and back as part of its Artemis II mission after overcoming rocket-fueling snags in a second key launch rehearsal this week, but cautioned that remaining prep work could warrant more time.

The U.S. space agency on Thursday night capped a nearly 50-hour rehearsal of the Artemis II launch countdown, fueling the rocket with some 730,000 gallons of propellant without running into the pesky hydrogen leaks that hobbled an initial rehearsal last month, officials said during a news conference.

Artemis program managers were elated that the Wet Dress Rehearsal, a comprehensive simulation of the Space Launch System’s launch-day countdown, went smoothly, but said remaining work ahead could still push the launch date further into NASA’s March launch window.

“I felt like last night was a big step in us earning our right to fly. So, felt really good, very proud of the team,” said NASA launch director Charlie Blackwell-Thompson.

Remaining work includes testing the rocket’s flight termination system and conducting a sweeping Flight Readiness Review, a day-long meeting of agency management during which they effectively double-check all rocket hardware and mission procedures before liftoff. – Reuters
