NASA’s newest space observatory could sniff exoplanet atmospheres for signs of life
Over the course of our existence, humanity has struggled to definitively answer the question: “Are we alone?”
Is Earth the only planet in the vast cosmic sea that contains life? As our technology becomes more advanced, we get closer and closer to the answer.
Our solar system contains a multitude of worlds, planetary bodies ranging from ice planets to gas giants with magnificent rings to rocky, terrestrial worlds like our own. But what lies out beyond our stellar neighborhood?
It’s only been in the last few decades that scientists have detected planets orbiting other stars. We call them exoplanets. Since that initial discovery, researchers have trained their telescopes on the cosmos in search of new and different worlds.
Their efforts were not in vain, as thousands of exoplanets have been detected. Now, scientists are starting to shift their focus to the individual planets and learning as much as they can about them. Do they contain life? What are they made of? What kind of atmosphere do they have?
These are the types of questions we hope to answer about the alien worlds that fill our universe.
One element essential to life on Earth is oxygen. Its presence is what scientists refer to as a biosignature. (These are the types of things NASA’s next Mars rover will look for.) A recent paper published in Nature Astronomy details a new technique that scientists are hoping will help them detect the presence of oxygen in exoplanet atmospheres.
Like methane, oxygen is a biosignature but its presence does not guarantee we will find life. There are plenty of non-biological processes that produce oxygen (as well as methane). However, if other biosignatures are detected in addition to oxygen, the chances of life increase significantly.
NASA’s Curiosity rover detected a methane cycle on Mars that varies with the seasons. However, its orbital counterparts — European spacecraft TGO and Mars Express — have not. The science team is working to identify what is causing the methane spikes as well as why it seems to disappear as it rises through the atmosphere.
“Oxygen is one of the most exciting molecules to detect because of its link with life, but we don’t know if life is the only cause of oxygen in an atmosphere,” Edward Schwieterman, an astrobiologist at UC Riverside and co-author on the study, said in a statement. “This technique will allow us to find oxygen in planets both living and dead.”
The new method was developed by a team led by Thomas Fauchez, a planetary scientist at NASA’s Goddard Space Flight Center. It is derived from the behavior of oxygen molecules in Earth’s atmosphere.
When oxygen molecules collide, they produce a signal—a very subtle dip in infrared radiation. Unfortunately, that signal is so faint that current observatories cannot detect it in distant planets. But that will soon change. NASA’s latest and greatest telescope, the James Webb Space Telescope (JWST) will come online sometime in the next few years. Fauchez’s team has shown that JWST, which will observe the universe in the infrared, should have what it takes to spot it.

“Before our work, oxygen at similar levels as on Earth was thought to be undetectable with Webb,” said Fauchez in a statement. “This oxygen signal is known since the early 1980s from Earth’s atmospheric studies but has never been studied for exoplanet research.”
In the meantime, NASA’s Mars 2020 rover will launch to the red planet in July. Once it’s on Mars, it will study Jezero Crater, the site of an ancient river delta and scan the region for signs of life (like oxygen, methane, and other biosignatures). The rover will also bag up bits of Mars to be returned to Earth at a later date.

SpaceX Board has set a Mars bonus for Elon Musk
SpaceX has given Elon Musk the goal to put one million people on Mars.
SpaceX’s board approved a compensation plan for Elon Musk that ties his pay directly to colonizing Mars and building data centers in outer space. The details surfaced this week after Reuters reviewed SpaceX’s confidential registration statement filed with the Securities and Exchange Commission, making it one of the first concrete looks inside the company’s financials ahead of a public offering.
The pay package will reportedly award Musk 200 million super-voting restricted shares if the company hits a market valuation milestone, with the most ambitious targets going further. To unlock the full award, SpaceX would need to reach a $7.5 trillion valuation and help establish a permanent human settlement on Mars with at least one million residents. Additional incentives are tied to developing space-based computing infrastructure capable of delivering at least 100 terawatts of processing power.
SpaceX wins its first MARS contract but it comes with a catch
Long before SpaceX filed anything with the SEC, Elon Musk had already spent years framing Mars colonization as an insurance policy against human extinction. The philosophy traces back to at least 2001, when Musk first began researching Mars missions independently, before SpaceX even existed. By 2002 he had founded the company with Mars as the stated long-term goal.
In a 2017 presentation at the International Astronautical Congress, Musk outlined the specific vision that still underpins SpaceX’s architecture today. He described a self-sustaining city on Mars requiring roughly one million people to become viable, the same number now written into his compensation package.
SpaceX’s Starship, still in active development, was designed from the ground up to support the eventual colonization of Mars. Musk has stated publicly that getting the cost per ton to Mars below $100,000 is necessary to make mass migration economically feasible. Everything from Starship’s payload capacity to its full reusability targets flows from that single constraint. One can say that Musk’s latest compensation package has put a formal valuation on Mars for the first time.
SpaceX is targeting an IPO around June 28, Musk’s birthday, at a valuation of approximately $1.75 trillion. Between the Mars rover contract, the Golden Dome software group, Space Force satellite launches, and now a pay structure built around interplanetary colonization, SpaceX has become the single most consequential contractor in American space and defense. The IPO will put a public price tag on all of it for the first time.

UPDATE: SpaceX’s Falcon Heavy that launched a Tesla into space is back on a mission
SpaceX Falcon Heavy returns after 18 months away to deliver a satellite that only it could carry.
UPDATE: 10:29 a.m. et: SpaceX is standing down from today’s Falcon Heavy launch of the ViaSat-3 F3 mission due to unfavorable weather. A new target date will be shared once confirmed.
After an 18-month absence, SpaceX’s Falcon Heavy is returning to mission on Monday morning when it’s scheduled to lift off from Launch Complex 39A at Kennedy Space Center at 10:21 a.m. EDT.
The mission is called ViaSat-3 F3, and the heavy satellite payload needs to reach geostationary orbit, sitting 22,236 miles above Earth where its speed matches the planet’s rotation. Getting a satellite that heavy to that altitude demands more thrust than a single-core Falcon 9 can deliver.
This marks the Falcon Heavy’s 12th flight overall since its debut in February 2018, and its first since NASA’s Europa Clipper mission in October 2024.
Arguably, the most exciting element for spectators will be watching the booster recoveries in action when the two side boosters, B1072 and B1075, will attempt simultaneous landings at Landing Zone 2 and the newer Landing Zone 40 at Cape Canaveral Space Force Station, while the center core will be expended over the ocean.
SpaceX wins its first MARS contract but it comes with a catch
Following satellite deployment, expected roughly five hours after launch, ViaSat-3 F3 will spend several months traveling to its final orbital slot before undergoing in-orbit testing, with service entry expected by late summer 2026
As Teslarati reported, NASA awarded SpaceX a $175.7 million contract on April 16, 2026, to launch the ESA Rosalind Franklin Mars rover aboard a Falcon Heavy no earlier than late 2028, which would mark the first time SpaceX has ever sent a payload to Mars. That contract came on top of an already deep pipeline that includes the Roman Space Telescope, the Dragonfly Saturn mission, and multiple national security payloads.
SpaceX executed 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. With Starlink surpassing 10 million subscribers and an IPO targeting a $1.75 trillion valuation still ahead, Monday’s launch is one more data point in a company that has quietly become the backbone of both commercial and government space access worldwide.

The FCC just said ‘No’ to SpaceX for now
SpaceX is fighting the FCC for spectrum that could put satellites inside every smartphone.
SpaceX was dealt a new setback on April 23, 2006 by the Federal Communications Commission (FCC) after the U.S. government agency dismissed the company’s petition to access a Mobile Satellite Service spectrum that would allow direct-to-device (D2D) capabilities.
The FCC regulates communications by radio, television, wire, and cable, which also includes regulating D2D technology that lets your existing smartphone connect directly to a satellite orbiting Earth, the same way it would connect to a cell tower.
Elon Musk’s SpaceX has been building toward this through its Starlink Mobile service, formerly called Direct-to-Cell, in partnership with T-Mobile. The service officially launched on July 23, 2025, starting with messaging and expanding to broadband data in October of that year.

It’s worth noting that SpaceX is not alone in this race. AT&T and Verizon have their own satellite texting deals with AST SpaceMobile, while Verizon separately offers free satellite texting through Skylo on newer phones.
The regulatory foundation for all of this dates to March 14, 2024, when the FCC adopted the world’s first framework for what it called Supplemental Coverage from Space, allowing satellite operators to lease spectrum from terrestrial carriers and fill gaps in their coverage. On November 26, 2024, the FCC granted SpaceX the first-ever authorization under that framework, approving its partnership with T-Mobile to provide service in specific frequency bands. SpaceX then went further, completing a roughly $17 billion acquisition of wireless spectrum from EchoStar, which gave it the ability to negotiate with global carriers more independently.
Starlink’s EchoStar spectrum deal could bring 5G coverage anywhere
This recent ruling by the FCC blocked SpaceX from going further, protecting incumbent spectrum holders like Globalstar and Iridium. But the market momentum is already in motion. As Teslarati reported, SpaceX is targeting peak speeds of 150 Mbps per user for its next generation Direct-to-Cell service, compared to roughly 4 Mbps today, which would bring satellite connectivity close to standard carrier performance.
With a reported IPO targeting a $1.75 trillion valuation on the horizon, each spectrum fight, carrier deal, and regulatory win or loss now carries weight beyond just connectivity. SpaceX is quietly becoming the infrastructure layer underneath the phones of millions of people, and the FCC’s next move will help determine how much further that reach extends.
