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.
To prepare for drilling operations on Mars, the ESA, Italian space agency (ASI), and their commercial partners have been conducting tests with a replica – aka. the Ground Test Model (GTM). Recently, the test model completed its first round of sample collection, known as the Mars Terrain Simulation (MTS). The rover drilled into hard stone and extracted samples from 1.7 meters (5.5 feet) beneath the surface in a record-breaking feat.

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.
Some possibilities that have been considered are that humanity might be alone in the Universe, early to the party, or is not in a position to notice any yet. But in a recent study, Robin Hanson (creator of the Great Filter) and an interdisciplinary team offer a new model for determining when the aliens will get here. According to their study, humanity is early to the Universe and will meet others in 200 million to 2 billion years from now.

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.
Since then, astronomers have observed multiple objects impacting Jupiter, and it is expected that such impacts happen all the time (though unobserved). On September 13th, 2021, at 22:39:30 UTC (06:39:30 PM EDT; 03:39 PM:30 PDT), another impact was observed by multiple astronomers across the world. Images and a video of the impact (shown below) were captured by members of Société Lorraine d’Astronomie (SLA) in France.

Update: SpaceX has posted footage of what its like to see Earth from space when peering through the Resilience‘s cupola!
Today, history was made when the first all-civilian spaceflight launched from Launch Complex 39A at the NASA Kennedy Space Center in Florida. The purpose of this flight was to raise awareness and funds for the St. Jude Children’s Research Hospital and offer inspiration to people all over the world. Operated by SpaceX and sponsored by Jared Isaacman and Shift4Payments, this flight illustrates how accessibility to space is growing by leaps and bounds.
The mission began at 08:02 PM local time (05:02 PM PST) as the Crew Dragon spacecraft blasted off the launch pad atop a SpaceX Falcon 9. The rocket lifted off without any issues and soared into the night sky, rapidly gaining altitude towards orbit. During the next few minutes, the mission controllers at SpaceX watched in anticipation and waited for updates. They were joined by people all over the world watching the many live streams of the event.

So far we know of only two interstellar objects (ISO) to visit our Solar System. They are ‘Oumuamua and 2I/Borisov. There’s a third possible ISO named CNEOS 2014-01-08, and research suggests there should be many more.
But a new research letter shows that cosmic ray erosion limits the lifespan of icy ISOs, and though there may be many more of them, they simply don’t last as long as thought. If it’s true, then ‘Oumuamua was probably substantially larger when it started its journey, wherever that was.

On the evening of Wednesday, September 15th, history will be made as a crew of four commercial astronauts launch to orbit aboard the SpaceX Crew Dragon spacecraft Resilience. This flight will be operated by SpaceX, sponsored by Jared Isaacman (CEO of Shift4Payments) and represents the first all-civilian spaceflight in history. The launch will take place tonight at 08:00 PM EDT (05:00 PM PDT) from NASA’s Kennedy Space Center’s Launch Complex 39A.
The purpose of this mission is to raise awareness and funds for St. Jude Children’s Research Hospital, which specializes in the treatment of childhood cancers and pediatric diseases. At the same time, it demonstrates the accessibility of the modern space age, where civilians (and not just astronauts) can go to space. Universe Today’s own Alex Brock was on the scene to capture the pre-flight excitement, which was palatable!
