It’s not just rocket fuel propelling America’s first moonshot after a half-century lull. Rivalry with China’s flourishing space program is helping drive NASA’s effort to get back into space in a bigger way, as both nations push to put people back on the moon and establish the first lunar bases.
American intelligence, military and political leaders make clear they see a host of strategic challenges to the U.S. in China’s space program, in an echo of the U.S.-Soviet rivalry that prompted the 1960s’ race to the moon. That’s as China is quickly matching U.S. civil and military space accomplishments and notching new ones of its own. On the military side, the U.S. and China trade accusations of weaponizing space.
Senior U.S. defense officials warn that China and Russia are building capabilities to take out the satellite systems that underpin U.S. intelligence, military communications and early warning networks. There’s also a civilian side to the space race. The U.S. is wary of China taking the lead in space exploration and commercial exploitation, and pioneering the technological and scientific advances that would put China ahead in power in space and in prestige down on Earth.
“In a decade, the United States has gone from the unquestioned leader in space to merely one of two peers in a competition,” Sen. Jim Inhofe, an Oklahoma Republican, declared this week at a Senate Armed Services hearing. “Everything our military does relies on space.”At another hearing last year, NASA administrator Bill Nelson brandished an image transmitted by a Chinese rover that had just plunked down on Mars. “The Chinese government … they’re going to be landing humans on the moon” soon, he said. “That should tell us something about our need to get off our duff.”
NASA, the U.S. civilian space agency, is awaiting a new launch date this month or in October for its Artemis 1 uncrewed test moonshot. Technical problems scrubbed the first two launch attempts in recent weeks.China likewise aims to send astronauts to the moon this decade, as well as establish a robotic research station there. Both the U.S. and China intend to establish bases for intermittent crews on the moon’s south pole after that. Russia has aligned with China’s moon program, while 21 nations have joined a U.S.-initiated effort meant to bring guidelines and order to the civil exploration and development of space.
The parallel efforts come 50 years after U.S. astronauts last pulled shut the doors on an Apollo module and blasted away from the moon, in December 1972. Some space policy experts bat down talk of a new space race, seeing big differences from John F. Kennedy’s Cold War drive to outdo the Soviet Union’s Sputnik and be the first to get people on the moon. This time, both the U.S. and China see moon programs as a stepping stone in phased programs toward exploring, settling and potentially exploiting the resources and other untapped economic and strategic opportunities offered by the moon, Mars and space at large.
Beyond the gains in technology, science and jobs that accompany space programs, Artemis promoters point to the potential of mining minerals and frozen water on the moon, or using the moon as a base to go prospecting on asteroids — the Trump administration in particular emphasized the mining prospects. There’s potential in tourism and other commercial efforts. And for space more broadly, Americans alone have tens of thousands of satellites overhead in what the Space Force says is a half-trillion dollar global space economy.
Satellites guide GPS, process credit card purchases, help keep TV, radio and cell phone feeds going, and predict weather. They ensure the military and intelligence community’s ability to keep track of perceived threats. And in a world where China and Russia are collaborating to try to surpass the U.S. in space, and where some point to private space efforts led by U.S. billionaires as rendering costly NASA rocket launches unnecessary, the U.S. would regret leaving the glory and strategic advantages from developing the moon and space solely to the likes of Chinese President Xi Jinping and Tesla magnate Elon Musk, Artemis proponents say.
The moon programs signal that “space is going to be an arena of competition on the prestige front, demonstrating advanced technical expertise and know-how, and then also on the military front as well,” said Aaron Bateman, a professor of history and international affairs at George Washington University and a member of the Space Policy Institute.“People who are supportive of Artemis and people who see it as a tool of competition, they want the United States to be at the table in shaping the future of exploration on other celestial bodies,” Bateman said.
There’s no shortage of such warnings as the Artemis program moves toward lift-off. “Beijing is working to match or exceed U.S. capabilities in space to gain the military, economic, and prestige benefits that Washington has accrued from space leadership,” the U.S. intelligence community warned this year in its annual threat assessment.
A Pentagon-commissioned study group contended last month that “China appears to be on track to surpass the U.S. as the dominant space power by 2045.” It called that part of a Chinese plan to promote authoritarianism and communism down here on Earth. It’s sparked occasional heated words between Chinese and U.S. officials. China’s space program was guided by peaceable principles, Foreign Ministry spokesman Zhao Lijian said in July. “Some U.S. officials are constantly smearing China’s normal and reasonable outer space undertakings,” Zhao said.
Flying on the mightiest rocket ever built by NASA, Artemis 1 aims for a five-week demo flight that would put test dummies into lunar orbit. If all goes well with that, U.S. astronauts could fly around the moon in 2024 and land on it in 2025, culminating a program that will have cost $93 billion over more than a decade of work. NASA intends that a woman and a person of color will be on the first U.S. crew touching foot on the moon again.
Lessons learned in getting back to the moon will aid in the next step in crewed flights, to Mars, the space agency says. China’s ambitious space program, meanwhile, is a generation behind that of the United States. But its secretive, military-linked program is developing fast and creating distinctive missions that could put Beijing on the leading edge of space flight. Already, China has that rover on Mars, joining a U.S. one already there.
China carved out a first with its landing on the far side of the moon. Chinese astronauts are overhead now, putting the finishing touches on a permanent orbiting space station. A 1967 U.N. space treaty meant to start shaping the guardrails for space exploration bans anyone from claiming sovereignty over a celestial body, putting a military base on it, or putting weapons of mass destruction into space.“I don’t think it’s at all by coincidence or happenstance that it is now in this period of what people are claiming is renewed great-power competition that the United States is actually investing the resources to go back,” said Bateman, the scholar on space and national security.
“Time will tell if this turns into a sustained program.”Competition isn’t necessarily a bad thing, said Sen. Chris Coons, a Delaware Democrat and member of the Senate Foreign Relations Committee.Does rivalry with the Chinese “ensure greater sustained interest in our space program? Sure,” Coons said. “But I don’t think that’s necessarily a competition that leads to conflict.“I think it can be a competition — like the Olympics — that simply means that each team and each side is going to push higher and faster. And as a result, humanity is likely to benefit,” he said.
ISRO’s Aditya L1 Solar Mission Begins Studying Solar Wind, Collects Data on Energetic Particles
By Press Trust of India | Updated: 20 September 2023
After India’s solar mission, Aditya L1 began its journey towards Lagrange point 1 following a key manoeuvre, it has started studying energetic particles in the solar wind from space and will continue to do so for the rest of its life, a senior astrophysicist said. The study of the solar wind, the continuous flow of charged particles from the sun which permeates the solar system, will be carried out with the help of a device named Supra Thermal & Energetic Particle Spectrometer (STEPS), a part of the Aditya Solar wind Particle Experiment (ASPEX) payload.
“STEPS is now working from space. However, it was not sitting idle earlier. It has started functioning from within the magnetic field of the Earth since September 10 when Aditya was 52,000 kilometres above our planet,” Dr Dibyendu Chakrabarty, professor of Space and Atmospheric Sciences at the Physical Research Laboratory (PRL) said.
STEPS was developed by the PRL with support from the Space Application Centre (SAC) in Ahmedabad.
“During the travel time of four months (till Aditya L1 reaches its destination), it will study energetic particles in the solar wind. The data will help maintain the health and performance of our space assets in a better way,” Dr Chakrabarty told PTI.
The key aim of STEPS is to study the environment of energetic particles from the spacecraft’s position on the L1 point till it will function, he said. “The data from STEPS in the long term will also help us understand how space weather changes,” the space scientist said.
STEPS comprises six sensors, each observing in different directions and measuring supra-thermal and energetic ions. The data collected during the Earth’s orbits helps scientists to analyse the behaviour of particles surrounding the planet, especially in the presence of its magnetic field.
Aditya-L1, launched by the Indian Space Research Organisation (ISRO) on September 2, will go up to the First Lagrangian point, about 1.5 million km from the Earth ISRO on September 18 said on X: “Off to Sun-Earth L1 point! The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point.” Lagrangian points are where gravitational forces, acting between two objects, balance each other in such a way that the spacecraft can ‘hover’ for a longer period of time.
The L1 point is considered the most significant of the Lagrangian points, for solar observations, which were discovered by mathematician Joseph Louis Lagrange.
Elon Musk’s Neuralink Receives Approval to Start Brain Implant Human Trial for Paralysis Patients
By Reuters | Updated: 20 September 2023 10:20
Billionaire entrepreneur Elon Musk’s brain-chip startup Neuralink said on Tuesday it has received approval from an independent review board to begin recruitment for the first human trial of its brain implant for paralysis patients.
Those with paralysis due to cervical spinal cord injury or amyotrophic lateral sclerosis may qualify for the study, it said but did not reveal how many participants would be enrolled in the trial, which will take about six years to complete.
The study will use a robot to surgically place a brain-computer interface (BCI) implant in a region of the brain that controls the intention to move, Neuralink said, adding that its initial goal is to enable people to control a computer cursor or keyboard using their thoughts alone.
The company, which had earlier hoped to receive approval to implant its device in 10 patients, was negotiating a lower number of patients with the US Food and Drug Administration (FDA) after the agency raised safety concerns, according to current and former employees. It is not known how many patients the FDA ultimately approved.
Musk has grand ambitions for Neuralink, saying it would facilitate speedy surgical insertions of its chip devices to treat conditions like obesity, autism, depression and schizophrenia.
In May, the company said it had received clearance from the FDA for its first-in-human clinical trial when it was already under federal scrutiny for its handling of animal testing.
Even if the BCI device proves to be safe for human use, it would still potentially take more than a decade for the startup to secure commercial use clearance for it, according to experts.

ISRO’s Aditya-L1 Solar Mission Performs TL1I Manoeuvre, on Track to Reach Sun-Earth L1 Point
By ANI | Updated: 19 September 2023
The Indian Space Research Organisation (ISRO) announced on Tuesday that its maiden solar mission — Aditya-L1 — has performed the Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre successfully and the spacecraft was now in a trajectory that will take it to the Sun-Earth L1 point. ISRO also informed that it marked the fifth consecutive time that the ISRO had successfully transferred an object on a trajectory toward another celestial body or location in space.
A post on the ISRO official handle on social media platform X read, “Aditya-L1 Mission | Off to Sun-Earth L1 point | The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a manoeuvre after about 110 days. This is the fifth consecutive time ISRO has successfully transferred an object on a trajectory toward another celestial body or location in space.”
Earlier, a launcher carrying the Aditya-L1 spacecraft blasted off from the Satish Dhawan Space Station at Sriharikota in Andhra Pradesh. The primary objectives of India’s maiden solar mission include collecting scientific data and marking another milestone in India’s solar exploration efforts.
The agency had earlier posted on X, “Aditya-L1 Mission: Aditya-L1 has commenced collecting scientific data. The sensors of the STEPS instrument have begun measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth. This data helps scientists analyze the behaviour of particles surrounding Earth. The figure displays variations in the energetic particle environment, collected by one of the units.”
The Supra Thermal and Energetic Particle Spectrometer (STEPS) instrument, a part of the Aditya Solar Wind Particle Experiment (ASPEX) payload, also started its data-gathering operations earlier.
ISRO’s Aditya-L1 Solar Mission Begins Collecting Scientific Data in Earth’s Orbit
By Press Trust of India | Updated: 18 September 2023
India’s Aditya-L1 solar mission spacecraft has commenced collecting scientific data to help scientists analyse particles surrounding Earth, ISRO said on Monday.
The sensors on board India’s first solar observatory have begun measuring ions and electrons at distances greater than 50,000 km from Earth, ISRO announced in a post on X.
The national space agency said that the sensors on STEPS or the Supra Thermal & Energetic Particle Spectrometer instrument began measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth.
The instrument is a part of the Aditya Solar Wind Particle EXperiment (ASPEX) payload of Aditya L1.

STEPS comprises six sensors, each observing in different directions and measuring supra-thermal and energetic ions ranging from 20 keV/nucleon to 5 MeV/nucleon, in addition to electrons exceeding 1 MeV. These measurements are conducted using low and high-energy particle spectrometers.
The data collected during Earth’s orbits helps scientists to analyse the behaviour of particles surrounding the Earth, especially in the presence of its magnetic field.
STEPS was activated on September 10 at a distance greater than 50,000 km from Earth. This distance is equivalent to more than eight times the Earth’s radius, placing it well beyond Earth’s radiation belt region.
After completing the necessary instrument health checks, data collection continued until the spacecraft had moved farther than 50,000 km from Earth.
These STEPS measurements will persist during the cruise phase of the Aditya-L1 mission as it progresses toward the Sun-Earth L1 point. They will continue once the spacecraft is positioned in its intended orbit.
Data collected around L1 would provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena.
STEPS was developed by the Physical Research Laboratory with support from the Space Application Centre in Ahmedabad.
Aditya-L1 was launched by ISRO on September 2.
The spacecraft carries seven different payloads to study the Sun, four of which will observe the light from the Sun and the remaining three will measure in situ parameters of the plasma and magnetic fields.
Aditya-L1 will be placed in a halo orbit around the Lagrangian Point 1 (L1), which is 1.5 million km from the Earth in the direction of the Sun. It will revolve around the Sun with the same relative position and hence can see the Sun continuously.
Supermassive Black Hole Spotted Eating Sun-Like Star in Nearby Galaxy
By Reuters | Updated: 9 September 2023
Black holes, celestial objects known for their gluttony, usually eat stars unlucky enough to stray too close to them in one big gulp, annihilating them with their enormous gravitational pull. But some, it turns out, tend to snack rather than gorge.
Researchers said they have observed a supermassive black hole at the center of a relatively nearby galaxy as it takes bites out of a star similar in size and composition to our sun, consuming material equal to about three times Earth’s mass each time the star makes a close pass on its elongated oval-shaped obit.
Black holes are extraordinarily dense objects with gravity so strong that not even light can escape.
The star is located about 520 million light years from our solar system. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). It was observed being plundered by a supermassive black hole at the heart of a spiral-shaped galaxy.
As such black holes go, this one is relatively small, estimated to have a mass a few hundred thousand times larger than the sun. The supermassive black hole at the center of our galaxy, called Sagittarius A*, possesses about 4 million times the mass of our sun. Some other galaxies harbor supermassive black holes hundreds of millions times the mass of the sun.
Most galaxies have such black holes at their center, and the environment around them can be among the most violent places in the universe.
Most of the data used by the scientists in the new study came from NASA’s orbiting Neil Gehrels Swift Observatory.
The star was observed orbiting the black hole every 20 to 30 days. At one end of its orbit, it ventures near enough to the black hole to have some material from its stellar atmosphere sucked away, or accreted, each time it passes — but not so close as to have the whole star shredded. Such an event is called a “repeating partial tidal disruption.”
The stellar material that falls into the black hole heats up to around 3.6 million degrees Fahrenheit (2 million degrees Celsius), unleashing an immense amount of X-rays. Those were detected by the space observatory.
“What’s most likely to happen is the star’s orbit will gradually decay and it will get closer and closer to the supermassive black hole until it gets close enough to be completely disrupted,” said astrophysicist Rob Eyles-Ferris of the University of Leicester in England, one of the authors of the study published this week in the journal Nature Astronomy.
“That process is likely to take years at least — more likely decades or centuries,” Eyles-Ferris added.
This marked the first time that scientists had observed a sun-like star being repeatedly snacked upon by a supermassive black hole.
“There are lots of unanswered questions about tidal disruption events and exactly how the orbit of the star affects them,” Eyles-Ferris said. “It’s a very fast-moving field at the moment. This one has shown us that new discoveries could come at any time.”

Japan ‘Moon Sniper’ SLIM Lunar Spacecraft Launched Into Space Two Weeks After Chandryaan-3 Moon Landing
By Reuters | Updated: 7 September 2023
Japan launched its lunar exploration spacecraft on Thursday aboard a homegrown H-IIA rocket, hoping to become the world’s fifth country to land on the Moon early next year. Japan Aerospace Exploration Agency (JAXA) said the rocket took off from Tanegashima Space Center in southern Japan as planned and successfully released the Smart Lander for Investigating Moon (SLIM). Unfavorable weather led to three postponements in a week last month.
Dubbed the “Moon sniper”, Japan aims to land SLIM within 100 meters of its target site on the lunar surface. The $100-million (roughly Rs. 831 crores) mission is expected to start the landing by February after a long, fuel-efficient approach trajectory.
“The big objective of SLIM is to prove the high-accuracy landing … to achieve ‘landing where we want’ on the lunar surface, rather than ‘landing where we can’,” JAXA President Hiroshi Yamakawa told a news conference.
The launch comes two weeks after India became the fourth nation to successfully land a spacecraft on the Moon with its Chandrayaan-3 mission to the unexplored lunar south pole. Around the same time, Russia’s Luna-25 lander crashed while approaching the Moon.
Two earlier lunar landing attempts by Japan failed in the last year. JAXA lost contact with the OMOTENASHI lander and scrubbed an attempted landing in November. The Hakuto-R Mission 1 lander, made by Japanese startup space, crashed in April as it attempted to descend to the lunar surface.
SLIM is set to touch down on the near side of the Moon close to Mare Nectaris, a lunar sea that, viewed from Earth, appears as a dark spot. Its primary goal is to test advanced optical and image processing technology.
After landing, the craft aims to analyse the composition of olivine rocks near the sites in search of clues about the origin of the Moon. No lunar rover is loaded on SLIM.
Thursday’s H-IIA rocket also carried the X-Ray Imaging and Spectroscopy Mission (XRISM) satellite, a joint project of JAXA, NASA, and the European Space Agency. The satellite aims to observe plasma winds flowing through the universe that scientists see as key to helping understand the evolution of stars and galaxies.
Mitsubishi Heavy Industries manufactured the rocket and operated the launch, which marked the 47th H-IIA rocket Japan has launched since 2001, bringing the vehicle’s success rate close to 98 percent.
JAXA had suspended the launch of H-IIA carrying SLIM for several months while it investigated the failure of its new medium-lift H3 rocket during its debut in March.
Japan’s space missions have faced other recent setbacks, with the launch failure of the Epsilon small rocket in October 2022, followed by an engine explosion during a test in July.
The country aims to send an astronaut to the Moon’s surface in the latter half of the 2020s as part of NASA’s Artemis program.
