Two top astronomers say they’ve found evidence of life on comet 67P

The story of comet 67P/Churyumov-Gerasimenko and the European Space Agency’s Philae spacecraft just got a whole hell of a lot more interesting. After a semi-botched landing resulting in the spacecraft running out of battery power last November — as well as its subsequent awakening some seven and a half months later — two top astronomers claimed this week 67P potentially harbors a large quantity of microbial alien life.

Astronomers and astrobiologists Chandra Wickramasinghe and Max Willis arrived at this bold new assumption based on a theory that the comet’s organic-rich black crust is a product of living organisms present in the comet’s icy interior. Comet 67P, scientists say, contains icy seas and craters underneath its crust which most likely serve as a home for extremophile-like microbes. In other words, the comet could be carrying a host of alien life capable of living in the harshest of elements.

Further adding to the speculation is the fact the Rosetta space probe — the craft responsible for deploying Philae onto the comet — reportedly gathered odd organic material incredibly similar to viral particles as it floated around the comet. Wickramasinghe and Willis plan to report these findings in front of the Royal Astronomical Society’s meeting today in Wales.

The culmination of a 10+ year project, the European Space Agency’s Rosetta space probe reached the orbit of comet 67P/Churyumov-Gerasimenko last August. After studying the 2.5 mile-long comet’s surface for a matter of months, the ESA deployed its Philae spacecraft from the probe and attempted a landing. Unfortunately, the craft didn’t quite land where scientists intended and ran out of battery power just a few short days after reaching the surface.

Dormant for roughly 7 months, the Philae craft awoke from its slumber having sufficiently charged its solar-powered batteries. Operational again, the craft intended to undertake what it set out to do: take samples of the comet’s surface and analyze its chemical composition. Though Wickramasinghe desired to include life-detection device on the craft during planning some 15 years ago, the proposal was ultimately dismissed and the craft took to space purely for data collection. But even without the necessary tools to test for alien life, Wickramasinghe and Willis remain confident the data suggests microbial alien organisms are responsible for the comet’s icy composition.

“These are not easily explained in terms of prebiotic chemistry,” Wickramasinghe tells The Guardian, “the dark material is being constantly replenished as it is boiled off by heat from the sun. Something must be doing that at a fairly prolific rate.”

It appears Philae’s extraordinary journey bears much more scientific fruit than originally thought.

NASA needs a new approach for its challenging Mars Sample Return mission
An illustration of NASA's Sample Return Lander shows it tossing a rocket in the air like a toy from the surface of Mars.

NASA has shared an update on its beleaguered Mars Sample Return mission, admitting that its previous plan was too ambitious and announcing that it will now be looking for new ideas to make the mission happen. The idea is to send a mission to collect samples from the surface of Mars and return them to Earth for study. It's been a long-term goal of planetary science researchers, but one that is proving costly and difficult to put into practice.

The Perseverance rover has already collected and sealed a number of samples of Mars rock as it journeys around the Jezero Crater, and has left these samples in a sample cache ready to be collected.  However, getting them back to Earth in the previous plan required sending a vehicle to Mars, getting it to land on the surface, sending out another rover to collect the samples and bring them back, launching a rocket from the planet's surface (something which has never been done before), and then having this rocket rendezvous with another spacecraft to carry them back to Earth. That level of complexity was just too much to be feasible within a reasonable budget, NASA Administrator Bill Nelson announced this week.

Final communications sent to the beloved Ingenuity Mars helicopter
NASA’s Ingenuity Mars helicopter is seen here in a close-up taken by Mastcam-Z, a pair of zoomable cameras aboard the Perseverance rover. This image was taken on April 5, the 45th Martian day, or sol, of the mission.

Earlier this year, the beloved Mars helicopter Ingenuity ended its mission after an incredible 72 flights. Originally designed as a technology test intended to perform just five flights, NASA's helicopter was the first rotorcraft to fly on another planet and was such a success that it has already inspired plans for more exploration of distant planets using rotorcraft. Its mission came to an end, however, when it damaged one of its rotors, leaving it unable to safely fly.

Even then, the helicopter was still able to communicate by sending signals to the nearby Perseverance rover, which acted as its base station. Now, though, Perseverance is traveling away from the helicopter to continue its exploration of Mars. So this week, the NASA team on the ground met for the last time to communicate with Ingenuity, bringing the mission to a final close.

NASA gives green light to mission to send car-sized drone to Saturn moon
An artist's impression of NASA's Dragonfly drone.

NASA’s Mars helicopter mission is now well and truly over, but following in its footsteps is an even more complex flying machine that's heading for Saturn’s largest moon.

The space agency on Tuesday gave the green light to the Dragonfly drone mission to Titan. The announcement means the design of the eight-rotor aircraft can now move toward completion, followed by construction and a testing regime to confirm the operability of the machine and its science instruments.
