Yes, NASA Found Evidence of Ancient Life on Mars. Here’s the Real Story

Learn why scientists are cautiously optimistic about the potential biosignatures found in the Sapphire Canyon rock sample.

Just last week, NASA’s Perseverance rover dropped some major news from Mars that has everyone talking. A tiny rock sample, dramatically named “Sapphire Canyon,” is showing tantalizing hints of what scientists call biosignatures. In plain English? Potential signs that ancient, alien life might have once existed on the Red Planet.

Perseverance snagged this promising sample from a rock in Jezero Crater, which happens to be a dried-up ancient riverbed. The fact that this area was once flush with water is a huge deal, since that’s a key ingredient for life as we know it. While this isn’t a smoking gun for little green men, it’s a massive clue.

As one NASA scientist put it, finding proof of past life would seriously “increase the possibility that some form of life has survived” underground on Mars today — a pretty wild thought to chew on.

Life on Mars?

So, does this finally confirm that life once existed on Mars? It’s a very good start, and the most significant lead NASA has found so far. Dr. Rench was clear on this point. “This discovery significantly increases our chances of finding ancient signatures of life at Mars. It suggests the possibility of life on Mars several billion years ago. It does not provide any evidence for life on Mars today.”

The data collected by Perseverance using its onboard instruments (X-ray lithochemistry and NASA’s SHERLOC scanner) was peer-reviewed and appears promising, but it doesn’t absolutely confirm life. More tests and input are needed for that, and the samples could have been generated from a natural chemical process without the presence of life. But scientists are excited about these signs and eager to learn more.

What kind of Mars life are we talking about? It’s not the sort that comes in peace, or goes much of anywhere. The possible biosignatures indicate small, microbial life. Sapphire Canyon showed signs of vivianite and greigite. Vivianite, in particular, is found on Earth’s peat bogs and swamps, while greigite is a byproduct some earth microbes leave behind. Think of this finding like a potential algae or swamp scum.

NASA is working on analyzing the data, running more tests and sharing the results with other scientists around the world to see what more they can learn. There’s a lot to rule out, from accidental sample contamination to the likelihood of nonorganic origins. That’s tough to do from millions of miles away, but NASA is on the case.

Tehran urges return to June deal, oil prices rise as Trump vows to hit Iran ‘hard’

Iran launched an attack on two American bases in Jordan on Monday in retaliation for the U.S. attack on its Larak Island.

Oil prices extended gains on Tuesday as traders mulled the threat of escalation, following the resumption of U.S.-Iran military strikes and more turmoil on the Strait of Hormuz.

A tanker was struck by three unknown projectiles while transiting the Strait of Hormuz on Monday, the UK Maritime Trade Operations agency said in a post on Tuesday, Asia time.

The tanker was sailing in the southern shipping lane close to the Omani coast, the UKMTO said, adding that no casualties were reported.

Iran launched an attack on two American bases in Jordan on Monday in retaliation for the U.S. attack on its Larak Island. American forces targeted two Iranian rocket launchers on Larak Island on Sunday, reportedly killing three, saying that Tehran intended to launch rockets carrying sea mines into the Hormuz Strait.

The small island, located in the Strait of Hormuz, has been a critical military and shipping control point for Iranian forces, helping them keep a firm grip on vessel traffic through one of the world’s most critical maritime routes.

Iranian President Masoud Pezeshkian told the Shanghai Cooperation Organisation Summit on Tuesday that Tehran would immediately reciprocate if Washington agreed to return to its commitments under the interim deal signed in June, according to the Iranian Student News Agency.

The back-and-forth hostilities marked the first time that the U.S. and Iran traded strikes in over a month.

While neither side appeared to be seeking a return to full-scale war, both signaled they were prepared to respond to further attacks. “We are going to hit them hard,” President Donald Trump told Fox News on Monday, saying that “there will be a response” to Iran’s attacks on U.S. military bases in the region.

Analysts largely view the U.S. attack on Larak Island as an attempt to break a deadlock rather than a shift in strategy. “By hitting the launchers rather than broader Iranian military infrastructure, the U.S. appears to be punishing a specific behaviour rather than, at least for now, broadening its war aims,” said Ali Vaez, deputy program director at International Crisis Group.

“It is enforcing the blockade,” said Jason Brodsky, policy director of United Against Nuclear Iran, adding that the Trump administration’s goal was to further degrade Tehran’s capabilities to mine the Strait of Hormuz, while focusing on economic coercive measures as the midterm elections approach.

Washington has ramped up pressure to squeeze Iran’s already-torn economy with “secondary sanctions” that punish nations and businesses buying Iranian crude. U.S. Treasury Secretary Scott Bessent said Monday, on the sidelines of the Group of 20 finance ministers’ gathering, that Iran was “lashing out kinetically” because the new sanctions were taking a toll on its economy.

Speaking from the Oval Office on Monday, Trump reportedly said Iran’s financial systems, armed forces, and governing body have largely degraded. “It doesn’t mean we won’t smack them to see what happens,” the president said.

The war, now stretching into its seventh month, has disrupted global energy supplies and sent shockwaves through global financial markets. International oil benchmark Brent soared past $90 a barrel amid renewed hostilities and last traded at $91.35 as of 2:17 a.m. ET on Tuesday. U.S. West Texas Intermediate futures added 1.07% to $86.68 per barrel.

“This is fundamentally an endurance contest,” said Brodsky, as Trump has demonstrated an “unpredictability” that should concern the Iranians, and Tehran may lash out more aggressively militarily as the economic pressure mounts.

Hello, this is Leonie Kidd coming to you from London.

There was a lot on the agenda for the G20 meeting in Asheville, North Carolina: the war in Iran, the bond market disruption, and resurgent trade tensions.

What did not seem to be clear, was the attendance of Russian Finance Minister Anton Siluanov, in a move that has left European officials in dismay.

Read on for more.

What you need to know today

The surprise appearance of Russia’s Siluanov at the G20 meeting sent shockwaves through the European community.

It marked his first in-person attendance of the summit since Russia’s invasion of Ukraine in 2022 and seemed to blindside the European attendees. Officials opposed appearing in the traditional G20 family photo with Russia, which was ultimately taken without Siluanov present.

U.S. Treasury Secretary Scott Bessent met with Siluanov on the sidelines of the event, and reportedly told the Russian official that no sanctions relief or new agreements with Moscow were possible, as long as the war in Ukraine continues.

Meanwhile, Indian Prime Minister Narendra Modi called on Russian President Vladimir Putin to cease his “endless war” in Ukraine, as the two leaders met at the Shanghai Cooperation Organization summit in Kyrgyzstan on Monday.

Strait back to strikes

Tensions with Iran also escalated over the weekend.

U.S. President Donald Trump threatened to hit Iran “hard” in an interview with Fox News on Monday, saying that “there will be a response” to Iran’s attacks on U.S. military bases in the region.

Meanwhile, another tanker was struck while transiting through the Strait of Hormuz on Monday.

Venezuela oil

The White House has announced that Venezuela has granted U.S.-backed North America Blue Energy Partners 100-year concessions for 17 oil fields in the country. Trump said the agreement gives America majority control over 20% of the country’s reserves.

Fast fashion fall

Anthony Scaramucci on failure, ego and 11 days in the White House

Anthony Scaramucci’s career has included high-profile successes and setbacks.

In this episode of “Executive Decisions,” the SkyBridge Capital founder reflects on leaving Goldman Sachs to build his own business, why insecurity led him into the wrong job early in his career and the pride and ego that influenced his decision to join the Trump administration.

After being fired from the White House after just 11 days, Scaramucci was advised to disappear from public life. Instead, he chose to face his critics — a decision he says became part of a wider reckoning with his mistakes, his relationships and himself.

Bessent tells Russia no economic relief will come until Ukraine war ends as Europe isolates Moscow at G20

U.S. Treasury Secretary Scott Bessent told Russian Finance Minister Anton Siluanov that no economic relief or new agreements can be made while the war in Ukraine continues, during a rare G20 meeting in Asheville, North Carolina.

U.S. Treasury Secretary Scott Bessent reportedly told Russian Finance Minister Anton Siluanov that no sanctions relief or new agreements with Moscow were possible, as long as the war in Ukraine continues.

The two officials met on the sidelines of a Group of 20 finance leaders gathering in Asheville, North Carolina.

Bessent’s remarks came as Siluanov’s first in-person appearance at the summit since Russia’s invasion of Ukraine in 2022 drew objections from other European leaders. European governments have planned to expand sanctions to further squeeze Moscow’s economy and finances.

The rare meeting underscored Washington’s willingness to reopen high-level diplomatic channels with Moscow, even as European allies have intended to keep the nation isolated while the war continues.

Bessent made it clear to Siluanov that “nothing is possible until the war is over,” when the Russian minister brought up other areas of mutual interest, Reuters reported.

The meeting centered on President Donald Trump’s peace plan for Ukraine and economic growth, according to Axios, while Russia’s finance ministry described the discussions as covering financial cooperation between the two nations within the G20 framework.

Russia’s surprise return to the table sparked dismay among European officials, who opposed appearing with Siluanov in the traditional G20 photo, which was ultimately taken without the Russian minister.
