Feb 2, 2022 · The new work extends the potentially habitable period on Mars by about 500 million years, into the late Hesperian age. “Discerning the climate of Mars approximately three billion years ago is challenging because the Martian surface features do not seem to fully support either a warm and wet or cold and dry climate during that time,” said ...

Oct 29, 2024 · A new paper in Nature Communications makes their most compelling case to date that Mars’ life-enabling magnetic field could have survived until about 3.9 billion years ago, compared with previous estimates of 4.1 billion years — so hundreds of millions of years more recently.
Feb 2, 2022 · It also increases the time period for an Earth-like climate on Mars.’ The late Noachian period (from 4.1 billion to 3.5 billion years ago) is the period usually thought to be habitable on Mars, with significant rain near the equator, as demonstrated by the presence of valley networks — features formed by erosion from flowing water — at ...
Nov 4, 2024 · A recent paper in Nature Communications presents their strongest evidence yet that Mars ‘ life-protecting magnetic field, or “dynamo,” could have lasted until about 3.9 billion years ago. This contrasts with older estimates that placed its demise around 4.1 billion years ago, suggesting the dynamo persisted for hundreds of millions of ...
Feb 2, 2022 · While more evidence of shocked zircons dating back to this period would be welcome, there only needs to be one good example to display evidence of bombardment, he says. Science Advances DOI: 10. ...
Evidence shows Mars was once warm and wet and had an atmosphere. In the ancient Noachian Period, between 3.7 billion and 4.1 billion years ago, Mars also had surface water. If this is correct, Mars may have been habitable (though that doesn't necessarily mean it was inhabited.)

Sep 8, 2021 · The question is, “Is it habitable and for whom?”. Mars is hundreds of degrees colder than Earth; it has a hundred times less atmosphere and that atmosphere has hardly any oxygen. But there may be other forms of life that could have evolved that aren’t very much like us but are very much like the early forms of life that evolved on Earth.
