In about a year (Sept. 20th, 2021), the Rosalind Franklin rover will depart for Mars. As the latest mission in the ESA’s and Roscosmos’ ExoMars program, Rosalind Franklin will join the small army of orbiters, landers, and rovers that are working to characterize the Martian atmosphere and environment. A key aspect of the rover’s mission will involve drilling into the Martian soil and rock and obtaining samples from deep beneath the surface.

Gamma rays strike Earth from all directions of the sky. Our planet is bathed in a diffuse glow of high-energy photons. It doesn’t affect us much, and we don’t really notice it, because our atmosphere is very good at absorbing gamma rays. It’s so good that we didn’t notice cosmic gamma rays until the 1960s when gamma-ray detectors were launched into space to look for signs of atomic weapons tests. Even then, what we noticed were intense flashes of gamma rays known as gamma ray bursts.

Thinking outside the box has always been a strong suit of space exploration.  Whether taking a picture of the Earth in a sunbeam or attempting to land a rocket on a floating ship, trying new things has been a continual theme for those interested in learning more about the universe.  Now, a team from the University of Manchester has come up with an outside-the-box solution that could help solve the problem of building infrastructure in space – use astronauts themselves as bioreactors to create the building blocks of early colonies.

Dust devils are generally used as a trope in media when the writers want to know that an area is deserted. They signify the desolation and isolation that those places represent. Almost none of the settings of those stories are close to the isolation of Perseverance, the Mars rover that landed on the planet earlier this year.  Fittingly, the number of dust devils Perseverance has detected is also extremely high – over 300 in its first three months on the planet. 

History has viewed mining as a job that requires a lot of heavy machinery and physical labor.  Pulling valuable material out of the ground has been necessary for human progress for thousands of years.  That progress has led to an alternative method of getting those resources out of the Earth or other celestial bodies. The new technique relies on a symbiotic life partner that has co-habited with us for millennia – bacteria. A recent experiment conducted by ESA’s Biorock investigation team shows that this process – known as “biomining” – might be the most effective way to collect some materials in space.

Seventy years ago, Italian-American nuclear physicist Enrico Fermi asked his colleagues a question during a lunchtime conversation. If life is common in our Universe, why can’t we see any evidence of its activity out there (aka. “where is everybody?”) Seventy years later, this question has launched just as many proposed resolutions as to how extraterrestrial intelligence (ETIs) could be common, yet go unnoticed by our instruments.

In 1994, the Comet Shoemaker-Levy 9 (SL9) impacted Jupiter, which had captured the comet shortly before (and broken apart by its gravity). The event became a media circus as it was the first direct observation of an extraterrestrial collision of Solar System objects. The impact was so powerful that it left scars that endured for months and were more discernible than Jupiter’s Great Red Spot.
