New research suggests Mars may have sustained its warmth and held on to its water billions of years ago .

Researchers at Harvard John A. Paulson School of Engineering and Applied Sciences studied Mars 's atmosphere.

They found that Mars experienced episodic warm periods around 4 to 3 billion years ago , with each episode lasting at least 100,000 years .

These warm periods would have been driven by Mars losing water from its atmosphere to the ground.
