NASA has taken to its blog to give an update on the recent flight by the helicopter Ingenuity and sample activities being conducted by Perseverance.
NASA Jet Propulsion Laboratory took to Twitter on September 28 to announce that the Mars helicopter Ingenuity has completed its 33rd flight, soaring 365 feet over the Martian surface at an altitude of 33 feet. Ingenuity completed its relocation in 55.2 seconds, nearly being airborne for an entire minute. For those that don't know, Ingenuity is acting as NASA's newest Mars rover, Perseverance's scout, with the Ingenuity team using the small helicopter to look for prime locations to explore with the rover.
Ingenuity is used to look for locations and map strategic pathways for Perseverance to travel to and inspect. If determined to be a viable sample location, the rover will collect a sample which will eventually be transported back to Earth sometime in the late 2020s. For now, many samples are being taken, with NASA recently announcing a failure at sample collection with a rock nicknamed Chiniak. As explained on the NASA Mars website, Perseverance attempted an abrasion on the target rock and discovered that the target broke apart, preventing any future science operations.
NASA's Double Asteroid Redirection Test (DART) spacecraft collided with asteroid Dimorphos on September 26, marking the very first planetary defense mission.
NASA's DART spacecraft successfully collided with the asteroid Dimorphos of the binary asteroid system. Dimorphos is a moonlet that orbits its larger companion asteroid Didymos. NASA's plan was to demonstrate that a human-made spacecraft is capable of altering the orbit of the smaller asteroid Dimorphos by colliding a high-speed spacecraft into its surface. The test was a success in terms of collision, and now dozens of telescopes are pointed at Dimorphos to measure the impact and to see if the asteroid's orbit was changed.
Famous telescopes such as the James Webb Space Telescope (JWST) and the Hubble Space Telescope have been used to observe just before the impact and the following minutes/hours after. Despite the multiple telescopes pointed at the Didymos-Dimorphos system, scientists argue that the study on DART's impact can't be completed without a close-up inspection that would provide accurate data.
The James Webb Space Telescope and the famous Hubble Space Telescope have teamed up provide two unique views of NASA's DART spacecraft colliding with an asteroid.
NASA has taken to its social channels to showcase the differences between the two famous telescopes, with the space agency posting on the Hubble Twitter account "after" shots from the Double Asteroid Redirection Test (DART) impact. The images shown above in a GIF showcase NASA's spacecraft that intentionally collided with the asteroid Dimorphos in the very planetary defense mission.
As explained in NASA's recent blog post, the space agency decided to crash a spacecraft into the asteroid to see if the impact was able to change the orbit of the asteroid. If proven effective, NASA will have unlocked Earth's first planetary weapon used to protect our planet from dangerous asteroids. Observations were conducted with Webb and Hubble, marking the first time the telescopes have simultaneously captured imagery from the same target, according to NASA administrator Bill Nelson.
Engineers from West Virginia University are working on robots tasked with improving on-the-job safety for retail workers. Researchers want to test the robot in actual grocery stores after the locations are closed, providing a more accurate testbed environment.
As part of $367,000 in funding from the National Science Foundation, WVU researchers want to analyze workplace dangers - and find ways to reduce falling risks in retail stores. The robots can provide situational awareness, monitor risks and offer walkability maps, and should be able to help reduce the number of occupational injuries related to slips and falls.
Instead of trying to rely on a security camera to identify and detect workplace hazards, the robot equipped with a camera can move closely to the spill area - and is able to identify how slippery it is.
Artificial intelligence company Nala Robotics has introduced The Wingman, a self-cleaning autonomous robot that can be used in fast food restaurants.
The Wingman can pick up and load frying baskets with French fries, chicken wings and other types of frozen food, dip the basket in oil, and shake off any excess oil once finished. Once collected, the foods can be dispensed to individual seasoning bins so spices and sauces and can be added in the appropriate proportions.
Nala Robotics uses artificial intelligence paired with a high-performance camera and vision systems to support a built-in clean in place functionality - and ensure all foods are made to desired high quality.
The Baltic Sea is receiving an extremely large dosage of methane gas following multiple leaks being identified in Russia's gas pipelines Nord Stream 1 and Nord Stream 2.
Researchers are rushing to attempt to measure the effects of the pipeline leak, but estimations are difficult to conclude as the situation is ongoing. What is known is that four major leaks have been identified so far and that European leaders have accused Russia of sabotaging Nord Stream 1 and Nord Stream 2 as a way to attack the West over its condemnation of Russia's invasion of Ukraine.
Experts are now sounding the alarm on the environmental impact of high amounts of methane gas leaking into the Baltic Sea. Bloomberg reports that a circle with a diameter of approximately 3,200 feet and growing has been spotted bubbling with natural gas pouring up from the below pipeline. Satellites have already been used to get a birds-eye view of the impacted area. According to Russia, the European leaders are "stupid" to suggest that the nation would destroy its own pipelines.
Archaeologists in Prague are rejoicing at the discovery of a monumental building that is estimated to have been built 7,000 years ago.
Experts discovered the large building more accurately described as a roundel in Prague's district of Vinor, and according to researchers working at the dig, the relic of a past time is in extremely good condition. A roundel is a large circular structure from the Neolithic period between 4600 and 4900 BC. These structures are much older than the Great Pyramids of Giza or Stonehenge, which are estimated to have been constructed from 2550 to 2490 B.C and 2,500 BC, respectively.
Miroslav Kraus, who is in charge of the research, explains that despite the extreme significance of such a structure being discovered, researchers are yet to identify what roundels were actually used for. Kraus gave one theory to reporters, which suggests that these large structures could have been a focal point for trade, much like a market, or religious cults used them to perform rites of passage.
A study on climate change and trees titled "The effect of carbon fertilization on naturally regenerated and planted US forests" has been published in the journal Nature Communications.
Researchers from the Ohio State University have now determined how much climate change, specifically excess carbon dioxide in the atmosphere, has contributed to the growth of different species of trees. Trees help buffer the effects of climate change on the planet by sequestering carbon dioxide from the atmosphere, which has increased wood volume, or biomass, in a process known as carbon fertilization.
The phenomenon refers to the influx of carbon dioxide into a plant, increasing the rate at which it can photosynthesize to fuel growth, using the sun's energy, water, and other nutrients. Though higher carbon dioxide levels can be detrimental to natural systems and infrastructure worldwide, trees have used this increased availability to grow 20 to 30 percent larger than trees only three decades ago.
NASA deputy administrator Pam Melroy spoke during a presentation at the International Astronautical Congress 2022 in Paris, France on September 20th, detailing NASA's plans for its Moon to Mars exploration program.
Melroy stated that NASA's overarching goal is for the agency "to create a blueprint for sustained human presence and exploration throughout the solar system," and that to do this, NASA will need to identify specific objectives it wants to achieve. She noted that in the past, NASA has created capabilities and gone on to do what those capabilities allow them to achieve, but to "truly be aspirational and strategic," the agency has to "know what the goal is, even if we know we're not fully ready to do everything yet."
Following Melroy's presentation, NASA has released a revised version of its Moon to Mars objectives that will help direct investments into technologies to achieve them. The agency began with 50 draft objectives, and after opening up the discussion to international partners, the wider industry, and the public, have ended up with 63 final goals.
The official landfall confirmation comes from the National Hurricane Center Twitter account that posted at 3:05 pm EDT that Hurricane Ian has made landfall in Florida.
Shortly after the announcement from the National Hurricane Center, which stated that the "extremely dangerous" Category 4 hurricane had made landfall near Cayo Costa, Florida, NASA switched on its live stream to showcase the event from space. Officials reported Hurricane Ian brought wind speeds of 150 mph to the area it made landfall and that over the coming days, it's expected to move over central Florida, with forecasts estimating it will emerge over the western Atlantic by late Thursday.
NASA's video stream showcased just how large-scale a major storm can be, with the incredible views being captured by the cameras and astronauts aboard the International Space Station (ISS). In the days leading up to Hurricane Ian making landfall, astronauts aboard the ISS snapped photos of the major storm rolling into the region as it was gaining strength just south of Cuba. Officials warned Florida residents in the days before landfall was made to evacuate as Ian will cause rain, flooding, and destruction.
