NASA’s Perseverance rover has the task of a “robot geologist” on the Red Planet’s surface. While it tracks the region for geological discoveries, its final task is to let researchers on Earth get samples of the geological specimens. For this, the rover studies the rocks around it to understand the processes that may have formed the area as it is today. However, the exterior of a rock can be misleading because the planet’s surface causes dramatic changes to its appearance. The rover’s abrasion tool helps the rover drill through the outer layer to reach the interior original features of a rock.
As per a report by NASA, researchers cherish to look at these unaltered features through the rover’s camera before deciding whether to collect a core sample or not. More often than not, these unaltered interiors of rock give vital information about the planet’s history.
However, Perseverance’s tools to abrade rocks differ from its predecessors. NASA’s previous rovers Spirit and Opportunity had a Rock Abrasion Tool (RAT). This was a high-speed grinder with brushes. The brushes removed the rock dust and the weathered outer layer of the rock.
When we look at Perseverance’s abrasion patches on rocks, they may look similar to the ones made by Spirit and Observance. However, Perseverance goes about its business in a different way. According to NASA’s website, the sampling team was faced with the challenge to use the same drill to collect cores and regolith (external deposits), and to create abrasions on rock surfaces.
So they gave Perseverance a rotary percussive drill and a suite of interchangeable drill bits. The drill bits have an “unusual tooth pattern” using three lines of various lengths that are placed asymmetrically. The drill’s spinning and hammering movements cause a well-distributed crisscrossing on the rock and chip away the surface to reveal a patch of rock about 2 inches in diameter.
Then, Perseverance removes the cuttings and scratches by using the Gaseous Dust Removal Tool (GDRT). With four short puffs of nitrogen gas, the rover blows away the cuttings. Thereafter, the rover studies the rock and gives information that can help the team decide whether or not to collect a core sample of the rock. In order to collect the samples, Perseverance is equipped with over 40 titanium tubes.
SpaceX’s Inspiration4 Crew Shares Photos of Earth from Space – Beebom
If you are a space enthusiast like myself, I’m sure you love the mesmerizing views of the Earth from space shared by astronauts. Having said that, chances are you will love the breathtaking pictures recently shared by the astronauts in SpaceX’s Inspiration4 spacecraft, which took off from NASA’s Kennedy Space Center on September 15. It safely returned to Earth today.
The seven-seater SpaceX Crew Dragon spacecraft was recently launched from the Kennedy space center. Following the launch, astronauts from the Inspiration4 spacecraft shared four orbital photos of the Earth. You can check out the tweet right below.
The photos were taken from the cupola of the spacecraft, which is a dome-shaped, transparent viewing area that allows astronauts to get a unique glimpse of our planet from space. Not just that, SpaceX Inspiration4’s astronauts also shared a short video showing the sunset. You can check it out right here:
The astronauts include the Shift4 Payments CEO and founder Jared Isaacman, who financed the space mission and is currently the acting commander of the spacecraft, Air Force veteran Christopher Sembroski, physician assistant Hayley Arceneaux, and geoscientist Dr. Sian Proctor.
Now, it is worth mentioning that SpaceX’s Crew Dragon spacecraft can carry seven people onboard. However, the Inspiration4 mission only includes four astronauts aboard the spacecraft. As per reports, following the launch, the Inspiration4 spacecraft has now completed 15 orbits around Earth and is expected to complete a full orbit of the Earth every 90 minutes. If you want to monitor the progress of the flight, you can go to SpaceX’s official tracking website.

World's first space tourists splash down in their SpaceX capsule after three days in orbit – Yahoo Eurosport UK
Four space tourists safely splashed down in the Atlantic off the coast of Florida on Saturday, ending their trailblazing trip into orbit.
Their SpaceX capsule parachuted into the ocean just before sunset, not far from where their chartered flight began three days earlier.
SpaceX founder Elon Musk took them on as the company’s first rocket-riding tourists.
The fully automated Dragon capsule reached an unusually high altitude of miles 585km after Wednesday night’s liftoff, that’s 160km above the International Space Station.
The passengers were able to take in views of Earth through a big bubble-shaped window added to the top of the capsule.
