Nowadays, going green is one of the most popular things you can do. To go green means to reduce your environmental impact by replacing traditional products and practices with ones that cause less damage to the environment. This includes using renewable energy sources such as solar and wind power, reducing the use of electricity, eating more plant-based foods, recycling, avoiding plastic or single-use materials whenever possible, composting food waste and many more! Doing so helps protect our planet from further destruction caused by human activities.
Perseverance, a rover by NASA, just collected its 16th sample of rock which is named ” Berea”. It was taken from the top of Jezero Crater’s delta. This particular rock is very special because it contains some particles that could potentially give clues to how Mars looked like in the past and if any life forms were preserved in it. By collecting different types of rocks such as igneous and sedimentary rocks, scientists can understand more about Jezero’s history and how water shaped the planet both inside and out.
The rover is searching for stones that can be brought to Earth so it can be examined.
NASA’s Perseverance rover recently collected a sample from the top of Jezero Crater’s delta as part of their mission. This was the first campaign where they explored this area. After collecting 19 samples and 3 witness tubes, they also deposited 10 backup tubes onto the Martian surface which is a part of a bigger project by NASA and ESA (European Space Agency) called the Mars Sample Return campaign.
Scientists want to use lab equipment here on Earth to look at samples from Mars and figure out if there ever was life on the planet, as well as figuring out how water has shaped its surface and interior.
Scientists drilled out a rock sample from the “Berea” which was the 16th sample they were taking during their mission. They think the Berea sample was picked up by an old river and moved to this place, meaning that it can have come from far away outside of Jezero Crater. That’s why they believe this rock is so special and important.
Katie Stack Morgan, who works at NASA’s Jet Propulsion Laboratory in Southern California, said that one of the reasons why they chose this rock is because it has a lot of carbonate. She continued to say that on Earth, rocks with a lot of carbonate can actually be really good for keeping ancient fossils safe. If there are any signs of life at Jezero Crater, then this rock could hold its secrets.
NASA’s Perseverance rover is taking pictures of a rock it found on Mars, near a place called “Berea.” It used a special tool at the end of its arm to take samples from the rock. This cool animation was made using pictures taken by one of the cameras on front of the Rover.
Unlocking the Mysterious History of Mars’ Climate Through Carbonates
Scientists are trying to solve the mystery of what Mars’ climate was like when the planet had a lot of liquid water. Carbonates, which form due to reactions in liquid water, can tell scientists about the history changes in Mars’ climate. By studying the carbonate found in a sample called Berea, this team of scientist hopes to learn more and fill in any gaps they discover.
Ken Farley, the scientist of Perseverance Project from Caltech in Pasadena explained that “the special thing about this mission (Perseverance) is it has enabled us to explore a lot of places. We got the chance to collect igneous rocks from the flat crater floor and also found sedimentary rocks while exploring around a dried lake at the base of Jezero Crater. Now we are able to visit here and get coarse-grained sedimentary rocks which were deposited in what used to be a riverbed. Gathering these samples will help us discover more information about Jezero Crater billions of years ago!”.
The rover stored a sample in a tube and will keep driving up the hills of Jezero. It’s headed for Castell Henllys, which is the next turn in the empty river channel.
Exploring Mars with Perseverance
The goal of the Perseverance mission on Mars is to figure out if there used to be tiny organisms living there. The rover will explore and study the rocks, air, and climate on the Red Planet. It’ll also pave the way for people visiting Mars in the future. Plus, it’ll be the first mission ever to collect samples from Mars’ soil and save them for later use.
NASA and the ESA (European Space Agency) have been working together to send spaceships to Mars. Then, they’ll collect sealed samples from Mars’ surface and bring them back here on Earth. This mission is called the Perseverance mission, which is part of NASA’s plan to explore both the Moon and Mars. The JPL (Jet Propulsion Laboratory), handled by Caltech (California Institute of Technology) for NASA, built the rover used in this mission and manages its operations.
1. Scientists have figured out a way to use embryonic stem cells to grow new corneas.
2. Researchers have studied proteins related to a certain kind of inflammation in the eye when no tumor is present.
3. Doctors followed up on children from a village in Senegal over 12 years, observing how they were impacted by intestinal infection due to a parasite called schistosomiasis.
4. In Tanzania, scientists examined adult blood samples and cards with dried blood spots in order to detect DNA from the same parasite as mentioned before, Schistosoma mansoni.
In this passage, we look at how certain natural products from the ocean could help to fight against parasites causing diseases such as malaria, leishmaniasis and trypanosomiasis. In addition, we want to find out more about which areas are most affected by a disease called schistosomiasis in China using information technology and machine learning. Lastly, we also discuss how source management of echinococcosis might work in a certain area of Tibet, China.
