An exciting discovery on Mars is being overshadowed by turmoil at NASA, with budget cuts threatening to destroy a scientific legacy that has been built over decades. Yesterday, the agency shared a finding, published in Nature, of potential biosignatures identified by the Mars Perseverance rover in a 3.5 billion-year-old rock. “This very well could be the clearest sign of life …

NASA’s interim administrator Sean Duffy was fired up on Wednesday when he joined a teleconference to talk about new scientific findings that concerned the potential for life to have once existed on Mars. “This is exciting news,” said Duffy about an arrow-shaped rock on Mars found by NASA’s Perseverance rover. The rock contained chemical signatures and structures that could have …

Global warming is a tricksy beast. In some places, it’s transforming once-lush environments into barren deserts; in others, it’s doing essentially the opposite – albeit through an irony-fueled, monkey’s paw kind of interpretation of “re-green the Earth’s deserts”. Now, a new set of photos from NASA has laid bare a striking example of the latter effect – and it’s right …

Media are invited to see NASA’s fully assembled Artemis II SLS (Space Launch System) rocket and Orion spacecraft in mid-October before its crewed test flight around the Moon next year.   The event at NASA’s Kennedy Space Center in Florida will showcase hardware for the Artemis II lunar mission, which will test capabilities needed for deep space exploration. NASA and …

Skywatchers at Nasa have discounted a Harvard astronomer’s hypothesis that a rare interstellar object hurtling through our solar system is a relic from a civilization in another celestial neighborhood, and “could potentially be dire for humanity”. Avi Loeb, head of Harvard University’s Galileo Project, which searches for evidence of extraterrestrial intelligence, raised eyebrows by suggesting in a scientific paper in …

CAPE CANAVERAL, Fla. (AP) — NASA’s Mars rover Perseverance has uncovered rocks in a dry river channel that may hold potential signs of ancient microscopic life, scientists reported Wednesday. They stressed that in-depth analysis is needed of the sample gathered there by Perseverance — ideally in labs on Earth — before reaching any conclusions. While acknowledging the latest analysis “certainly …

NASA’s Perseverance Mars rover captured this image of a rocky area nicknamed “Cheyava Falls” on July 18, 2024, showing black “poppy seed” and larger “leopard spot” features. Researchers say a sample from the site reveals a tantalizing mix of details suggesting the potential presence of life, billions of years ago.
