With Mini Helicopter On Mars, NASA Hopes To Reinvent Flight 'On Another World' – KCCU

Published

 on


NASA’s miniature helicopter has safely deployed on Mars, setting the stage for a potential first flight on the Red Planet.

The four-pound helicopter, called Ingenuity, made the long journey from Earth stowed away underneath the Perseverance rover, which touched down in February. On Saturday, NASA confirmed that Ingenuity had safely separated from the rover’s belly and survived the four-inch drop to Mars’ surface.

The successful deployment brings NASA one step closer to its first attempt at testing the possibility of powered, controlled flight on another planet — which could one day allow scientists to observe and explore parts of Mars’ surface that rovers can’t reach.

NASA has compared Ingenuity’s experimental mission to the Wright brothers’ historic first flight in 1903, which ushered in the aerial age on Earth.

Ingenuity could take off as early as April 11, beginning a series of up to five test flights over Jezero Crater, where Perseverance landed, over a one-month period.

For now, the project is purely experimental, focused on demonstrating a new technology rather than assisting the Perseverance mission, which is currently roaming Mars for signs of ancient life and collecting samples from the planet’s surface.

The helicopter’s first flight will be a short one: Ingenuity will rise about 10 feet from the ground, hover in the air for under a minute, then land. But NASA says that the short trip would mark a major milestone.

“In alien conditions with almost no atmosphere, it’s reinventing flight on another world,” NASA said in its trailer for the mission. “If this 30-day experiment succeeds, it may pave the way for future aerial explorers.”

Surviving the 293 million mile journey to Mars and safely dropping from Perseverance were the first in a series of milestones the helicopter must cross before its inaugural flight. Next, Ingenuity will have to keep itself warm and functional through the extremely cold nights on Mars, which can see temperatures as low as minus 130 degrees Fahrenheit.

The helicopter previously relied on the rover’s power system, but now Ingenuity will have to depend on internal heaters and charge its batteries using a solar panel.

More technical hurdles for Ingenuity lie ahead, like taking off in Mars’ thin atmosphere.

Although the Red Planet has about one-third the gravity of Earth, its atmosphere at the surface is just 1% as dense. That means that without much air to push against, it’s more difficult to generate lift.

After receiving commands from Earth relayed through the Perseverance rover, the helicopter will also have to make each test flight without real-time input from mission control.

But if Ingenuity’s experiments prove successful, the technology could support future robotic and even human missions to Mars by providing new aerial viewpoints, capturing high-definition images or carrying small payloads from one site to another.

Researchers create a novel method of bioprinting neuron cells – Medical Xpress

Published

A group of researchers including a Concordia Ph.D. student have developed a new method of bioprinting adult neuron cells. They’re using a new laser-assisted technology that maintains high levels of cell viability and functionality.

Ph.D. candidate and 2020-21 Public Scholar Hamid Orimi and his co-authors present the feasibility of a new bioprinting technology they developed in a recent paper published in the journal Micromachines. They demonstrate how the methodology they created, called Laser-Induced Side Transfer (LIST), improves on existing bioprinting techniques by using bioinks of differing viscosities, allowing for better 3D printing. Orimi, his Concordia co-supervisor Sivakumar Narayanswamy in the Gina Cody School of Engineering and Computer Science, CRHMR co-supervisor Christos Boutopoulos and co-authors at the Université de Montréal first presented the method in the Nature journal Scientific Reports in 2020.

Orimi co-wrote the newer paper with lead author Katiane Roversi, Sebastien Talbot and Boutopoulos at UdeM and Marcelo Falchetti and Edroaldo da Rocha at Federal University of Santa Catarina in Brazil. In it, the researchers demonstrate that the technology can be used to successfully print sensory , a vital component of the peripheral nervous system. This, they say, is promising for the long-term development of bioprinting’s potential, including disease modeling, and implant fabrication.

Viable and functional

The researchers used dorsal root ganglion (DRG) neurons from the peripheral nervous system of mice to test their technology. The neurons were suspended in a bioink solution and loaded into a square capillary above a biocompatible substrate. Low-energy nanosecond laser pulses were focused on the middle of the capillary, generating microbubbles that expanded and ejected a cell-laden microjet onto the substrate below it. The samples were briefly incubated, then washed and re-incubated for 48 hours.

The team then ran several tests to measure the printed cells’ capacities. A viability assay found that 86 percent of the cells remained alive two days after printing. The researchers note that viability rates improved when the laser used lower energy. The thermomechanics associated with higher laser energy use was more likely to damage the cells.

Other tests measured neurite outgrowth (in which developing neurons produce new projections as they grow in response to guidance cues), neuropeptide release, calcium imaging and RNA sequencing. Overall, the results were generally encouraging, suggesting that the technique could be an important contribution to the field of bioprinting.

Good for people and animals

“In general, people often leap to conclusions when we talk about bioprinting,” Orimi says. “They think that we can now print things like for transplants. While this is a long-term objective, we are very far from that point. But there are still many ways to use this technology.”

Nearest at hand is drug discovery. The team hopes to get approval to continue their research into cell grafting, which can assist greatly in drug discovery, such as for nerve recovery medicines.

Another advantage to using this technology, Orimi says, is a decrease in animal testing. This not only has a humanitarian aspect—fewer animals will be euthanized to carry out experiments meant to benefit humans—but it will also produce more accurate results, since testing will be carried out on human, not animal, tissue.

Josh Richards Is Bringing Back The Woolly Mammoth – Forbes

Published

 on


Influencers are everywhere. 

They are at the MET Gala. They are walking the red carpet at the VMAs and now they are part of a team creating de-extinction technology which will bring the woolly mammoth back to the Arctic tundra within the next six years. 

Yes, you read that right. Extinction could be a thing of the past thanks to a TikToker and his friends.  

Josh Richards may be known to the masses as a TikTok star with over 40 million followers across social media but he has consistently proven to be a lot more than that. 

He has developed himself into a serial entrepreneur with companies ranging from Ani Energy, his energy drink which is now in Walmart, to Cross Check Studios, his production company with Mark Wahlberg, to Animal Capital, an $18 million venture capital fund that he started with his business partner Michael Gruen and former Goldman Sachs investment banker Marshall Sandman. 

This week, Richards and his fund Animal Capital announced their investment and advisory position into Colossal. They are a company that is using recent breakthrough advances in CRISPR genetic engineering, a new wave of disruptive conservation and restorative biology, which will eventually make extinction a thing of the past. 

The company was founded by tech entrepreneur Ben Lamm and world-renowned geneticist and serial biotech entrepreneur George Church, Ph.D. In addition to being a founder of Colossal, Church also serves as a Professor of Genetics at Harvard Medical School and is a Professor of Health Sciences and Technology at Harvard and MIT. 

Lamm said, “Genetic engineering holds an endless amount of opportunity for the future of humanity: From eradicating diseases to improving our ability to survive in changing climates. It is a breakthrough technology. As an entrepreneur, I’ve routinely found myself on the cusp of breakthrough technologies because I believe they mark powerful nexus events in the future of our species. I am incredibly excited and grateful for great partners and investors like Josh Richards and Animal Capital who see our long-term vision and can help contribute to the advancement of science and genomics.”  

Richards has been involved in the Animal Capital since its inception a year ago and his stamp is felt throughout the company. He, Gruen and Sandman brought on billionaire movie and technology mogul, Thomas Tull, to lead the round of funding. They brought Paramount Pictures President, Michael Ireland, and Billboard president, Julian Holguin, on as advisors. They got the billionaire Winklevoss twins to invest, as well as others. They’ve also been heavily involved in the company’s rollout and media strategy. 

Josh Richards said, “It is mind boggling that a 19-year-old kid from a small town in Ontario could be a part of a team that will change the world. To be involved in a company like this, that will change the world for the better, and allow my kids’ kids to have a better life, is truly an honor. My generation is the generation tasked with combatting climate change and creating a better world as we are the generation set to inherit the Earth.”

Sandman, the managing partner of Animal Capital, said, “The opportunity to invest in Colossal really speaks to the reason we originally started Animal Capital. Ben, George and the entire team are on a path to change the world and we are proud to be along for the journey”

Animal Capital’s other investments, include: Mental health technology, Whoop, crypto startup, WonderFi, which went public on the NEO two weeks ago and calendar-based social media platform, Saturn.

So, who knows, maybe we’ll see Josh Richards making a TikTok on a wooly mammoth. soon. Stay tuned.

SpaceX set to launch first all-civilian crew into orbit. Here’s what you should know – Globalnews.ca

Published

 on


The latest in a recent line of billionaire space enthusiasts prepared for liftoff on Wednesday along with three other private citizens aboard a SpaceX rocket ship, aiming to become the first all-civilian crew launched into Earth orbit.

The quartet of amateur space travelers, led by the American founder and chief executive of e-commerce firm Shift4 Payments Inc Jared Isaacman, were due for blastoff as early as 8 p.m. EDT (0000 GMT) from the Kennedy Space Center in Cape Canaveral, Florida.

The flight, with no professional astronauts accompanying SpaceX’s paying customers, is expected to last about three days from liftoff to splashdown in the Atlantic.

“Everything is go for launch,” SpaceX principal integration engineer John Insprucker declared about 3 1/2 hours before launch time in a SpaceX webcast of pre-liftoff activities.

A short time earlier, Isaacman, 38, and his crewmates – Sian Proctor, 51, Hayley Arceneaux, 29, and Chris Sembroski, 42 – strolled out of a SpaceX hangar waiving to cheering crowds of family, friends and well-wishers.

From there they were driven in two automobiles across the space center complex to a support building, where they donned the black-and-white spacesuits they will wear for liftoff.

They then headed to the launch pad to board a gleaming white SpaceX Crew Dragon capsule, dubbed Resilience, perched atop one of the company’s reusable Falcon 9 rockets and fitted with a special observation dome in place of the usual docking hatch.

This marks the debut flight of SpaceX owner Elon Musk’s new orbital tourism business, and a leap ahead of competitors likewise offering rides on rocket ships to customers willing to pay a small fortune for the exhilaration – and bragging rights – of spaceflight.

Isaacman has paid an undisclosed sum to fellow billionaire Musk to send himself and his three crewmates aloft. Time magazine has put the ticket price for all four seats at $200 million.

The mission, called Inspiration4, was conceived by Isaacman mainly to raise awareness and support for one of his favorite causes, St. Jude Children’s Research Hospital, a leading pediatric cancer center in Memphis, Tennessee.

Inspiration4 is aiming for an orbital altitude of 360 miles (575 km) above Earth, higher than the International Space Station or Hubble Space Telescope. At that height, the Crew Dragon will circle the globe once every 90 minutes at a speed of some 17,000 miles per hour (27,360 kph), or roughly 22 times the speed of sound.

Leap ahead of rivals

Rival companies Virgin Galactic and Blue Origin inaugurated their own private-astronaut services this summer, with their respective founding executives, billionaires Richard Branson and Jeff Bezos, each going along for the ride.

Those suborbital flights, lasting a matter of minutes, were short hops compared with Inspiration4’s spaceflight profile.

SpaceX already ranks as the most well-established player in the burgeoning constellation of commercial rocket ventures, having launched numerous cargo payloads and astronauts to the International Space Station for NASA. Two of its Dragon capsules are docked there already.

The Inspiration4 crew will have no part to play in flying the spacecraft, which will be operated by ground-based flight teams and onboard guidance systems, even though two crew members are licensed pilots.

Isaacman, who is rated to fly commercial and military jets, has assumed the role of mission “commander,” while Proctor, a geoscientist and former NASA astronaut candidate, has been designated as the mission “pilot.”

Rounding out the crew are “chief medical officer” Arceneaux, a bone cancer survivor turned St. Jude physician assistant, and mission “specialist” Sembroski, a U.S. Air Force veteran and aerospace data engineer.

The four crewmates have spent five months in rigorous preparations, including altitude fitness, centrifuge (G-force), microgravity and simulator training, emergency drills, classroom work and medical exams.

Inspiration4 officials have said the mission is more than a joyride.

Once in orbit, the crew will perform a series of medical experiments with “potential applications for human health on Earth and during future spaceflights,” the group said in media materials.

Biomedical data and biological samples, including ultrasound scans, will also be collected from crew members before, during and after the flight.

“The crew of Inspiration4 is eager to use our mission to help make a better future for those who will launch in the years and decades to come,” Isaacman said in a statement.
