India set to launch Earth-mapping satellite with NASA in March 2025
  • $1.5 billion NISAR mission will track the Earth’s changing surface
  • Satellite to scan nearly all of the planet’s land and ice surfaces

NEW DELHI: A new US-Indian satellite is set to be launched in March next year, India’s science minister said in parliament, updating lawmakers on the first Earth-mapping joint mission between NASA and the Indian Space Research Organization.

A collaboration agreement between ISRO and NASA was signed in 2014, with a targeted launch of the NASA-ISRO Synthetic Aperture Radar, or NISAR, project in 2024.

The satellite’s reflector, however, which is one of the main NASA contributions to the joint mission, had to undergo corrections, Science Minister Jitendra Singh told Parliament members on Wednesday.

“The Radar Antenna Reflector was delivered to ISRO by NASA in October 2024, which is reintegrated with the satellite and currently undergoing necessary tests,” Singh said in a written reply to a parliamentary query.

“Also, due to the eclipse season, the conditions are not conducive for deployment of NISAR’s boom and the Radar Antenna Reflector. In view of the aforementioned factors, NISAR is now likely to be launched during March 2025.”

The reflector is a key component of NISAR, and at 12m in diameter it will be the largest radar antenna of its kind ever launched into space.

It will focus transmitted and received microwave signals to and from the Earth’s surface, allowing the satellite to scan nearly all of the planet’s land and ice surfaces every week.

The data will provide a picture of how Earth’s surface moves horizontally and vertically.

“The information will be crucial to better understanding everything from the mechanics of Earth’s crust to which parts of the world are prone to earthquakes and volcanic eruptions,” the NASA Jet Propulsion Laboratory, which leads the US component of the project, said in last month’s mission update.

“The mission will be able to detect surface motions down to fractions of an inch. In addition to monitoring changes to Earth’s surface, the satellite will be able to track the motion of ice sheets, glaciers, and sea ice, and map changes to vegetation.”

The data is expected to help researchers better understand changes in the Earth’s surface and will also capture changes in its forest and wetland ecosystems.

Estimated to cost $1.5 billion, the NISAR mission is an equal collaboration between NASA and ISRO, with the US providing also the mission’s L-band radar, while the S-band radar is made in India.

The S-band radar is useful for monitoring crop structure and the roughness of land and ice surfaces, while the L-band instrument can penetrate denser forest canopies. Both sensors can see through clouds and collect data day and night.

The NISAR project marks the first time the Indian and US space agencies have cooperated on hardware development for Earth mapping.

Its launch will further add to India’s status as an emerging space superpower, following last year’s successful launch of Aditya-L1 — the country’s first solar observation mission, and the world’s second after the US Parker Solar Probe launched in 2021.

Also in 2023, ISRO’s Chandrayaan-3 moon rover made history by landing on the lunar surface, making India the first country to land near the lunar south pole and the fourth to land on the moon — after the US, the Soviet Union and China.


Denmark eyes new law to protect citizens from AI deepfakes

Denmark eyes new law to protect citizens from AI deepfakes

Denmark eyes new law to protect citizens from AI deepfakes
COPENHAGEN: In 2021, Danish video game live-streamer Marie Watson received an image of herself from an unknown Instagram account.
She instantly recognized the holiday snap from her Instagram account, but something was different: Her clothing had been digitally removed to make her appear naked. It was a deepfake.
“It overwhelmed me so much,” Watson recalled. “I just started bursting out in tears, because suddenly, I was there naked.”
In the four years since her experience, deepfakes — highly realistic artificial intelligence-generated images, videos or audio of real people or events — have become not only easier to make worldwide but also look or sound exponentially more realistic. That’s thanks to technological advances and the proliferation of generative AI tools, including video generation tools from OpenAI and Google.
These tools give millions of users the ability to easily spit out content, including for nefarious purposes that range from depicting celebrities Taylor Swift and Katy Perry to disrupting elections and humiliating teens and women.
Copyright law
In response, Denmark is seeking to protect ordinary Danes, as well as performers and artists who might have their appearance or voice imitated and shared without their permission. A bill that’s expected to pass early next year would change copyright law by imposing a ban on the sharing of deepfakes to protect citizens’ personal characteristics — such as their appearance or voice — from being imitated and shared online without their consent.
If enacted, Danish citizens would get the copyright over their own likeness. In theory, they then would be able to demand that online platforms take down content shared without their permission. The law would still allow for parodies and satire, though it’s unclear how that will be determined.
Experts and officials say the Danish legislation would be among the most extensive steps yet taken by a government to combat misinformation through deepfakes.
Henry Ajder, founder of consulting firm Latent Space Advisory and a leading expert in generative AI, said that he applauds the Danish government for recognizing that the law needs to change.
“Because right now, when people say ‘what can I do to protect myself from being deepfaked?’ the answer I have to give most of the time is: ‘There isn’t a huge amount you can do,’” he said, ”without me basically saying, ‘scrub yourself from the Internet entirely.’ Which isn’t really possible.”
He added: “We can’t just pretend that this is business as usual for how we think about those key parts of our identity and our dignity.”
Deepfakes and misinformation
US President Donald Trump signed bipartisan legislation in May that makes it illegal to knowingly publish or threaten to publish intimate images without a person’s consent, including deepfakes. Last year, South Korea rolled out measures to curb deepfake porn, including harsher punishment and stepped up regulations for social media platforms.
Danish Culture Minister Jakob Engel-Schmidt said that the bill has broad support from lawmakers in Copenhagen, because such digital manipulations can stir doubts about reality and spread misinformation.
“If you’re able to deepfake a politician without her or him being able to have that product taken down, that will undermine our democracy,” he told reporters during an AI and copyright conference in September.
The right balance
The law would apply only in Denmark, and is unlikely to involve fines or imprisonment for social media users. But big tech platforms that fail to remove deepfakes could face severe fines, Engel-Schmidt said.
Ajder said Google-owned YouTube, for example, has a “very, very good system for getting the balance between copyright protection and freedom of creativity.”
The platform’s efforts suggest that it recognizes “the scale of the challenge that is already here and how much deeper it’s going to become,” he added.
Twitch, TikTok and Meta, which owns Facebook and Instagram, didn’t respond to requests for comment.
Engel-Schmidt said that Denmark, the current holder of the European Union’s rotating presidency, had received interest in its proposed legislation from several other EU members, including France and Ireland.
Intellectual property lawyer Jakob Plesner Mathiasen said that the legislation shows the widespread need to combat the online danger that’s now infused into every aspect of Danish life.
“I think it definitely goes to say that the ministry wouldn’t make this bill, if there hadn’t been any occasion for it,” he said. “We’re seeing it with fake news, with government elections. We are seeing it with pornography, and we’re also seeing it also with famous people and also everyday people — like you and me.”
The Danish Rights Alliance, which protects the rights of creative industries on the Internet, supports the bill, because its director says that current copyright law doesn’t go far enough.
Danish voice actor David Bateson, for example, was at a loss when AI voice clones were shared by thousands of users online. Bateson voiced a character in the popular “Hitman” video game, as well as Danish toymaker Lego’s English advertisements.
“When we reported this to the online platforms, they say ‘OK, but which regulation are you referring to?’” said Maria Fredenslund, an attorney and the alliance’s director. “We couldn’t point to an exact regulation in Denmark.”
‘When it’s online, you’re done’
Watson had heard about fellow influencers who found digitally-altered images of themselves online, but never thought it might happen to her.
Delving into a dark side of the web where faceless users sell and share deepfake imagery — often of women — she said she was shocked how easy it was to create such pictures using readily available online tools.
“You could literally just search ‘deepfake generator’ on Google or ‘how to make a deepfake,’ and all these websites and generators would pop up,” the 28-year-old Watson said.
She is glad her government is taking action, but she isn’t hopeful. She believes more pressure must be applied to social media platforms.
“It shouldn’t be a thing that you can upload these types of pictures,” she said. “When it’s online, you’re done. You can’t do anything, it’s out of your control.”
