The spent Falcon 9 booster from a recent Starlink mission turned into brilliant, blazing fireballs as it re-entered the atmosphere over the Pacific Northwest the evening of March 25. But an entire fuel tank from the rocket made it all the way to the ground, turning up on a farm in Washington state.
Like shooting stars on steroids, the space debris sizzled across the sky as the rocket broke apart and burned up. Harvard astronomer Jonathan McDowell was quick to identify the singed junk as the remains of the second stage from a March 4 launch.
Normally these rockets make a “deorbit burn” so that they burn up promptly and in a more controlled manner right after their work is done. This particular rocket missed its deorbit burn and took its time falling towards an eventual demise over three weeks later.
The vast majority of space junk burns up completely or lands in the ocean. With this rocket’s fate essentially left to chance, it instead put on a spectacular show for PNW and dropped its Composite-Overwrapped Pressure Vessel (basically a propellant tank) in rural Grant County in secret.
But the secret was soon discovered by a farmer who reported it to law enforcement and requested to remain unidentified.
The Grant County Sheriff’s office shared images of the tank and the four-inch deep indentation it made in the ground.
Suspecting it might be related to the unusual sight a few days earlier, the Sheriff’s office contacted SpaceX, which confirmed it appeared to be part of a Falcon 9 and sent employees to retrieve it.
“Of course we didn’t have a protocol for this, so we just erred on the side of returning someone’s property to them,” Grant County Sheriff’s spokesperson Kyle Foreman told The Verge.
Score one for the resilience of composite materials. The tank was likely fairly lightweight, hence the indentation rather than a crater.
Still, you’d need one strong umbrella to protect against a tank like this if it ever fell all the way from space on to your head.
SpaceX launches amateur crew on private Earth-circling trip – Al Jazeera English
SpaceX’s first private flight has been launched into orbit with two contest winners, a healthcare worker and their rich sponsor on board, the most ambitious leap yet in space tourism.
The launch on Wednesday night was the first time a spacecraft circled Earth with an all-amateur crew and no professional astronauts.
“Punch it, SpaceX!” the flight’s billionaire leader, Jared Isaacman, urged moments before liftoff.
The Dragon capsule’s two men and two women are looking to spend three days circling the planet from an unusually high orbit – 160km (100 miles) higher than the International Space Station – before splashing down off the Florida coast this weekend.
It is SpaceX founder Elon Musk’s first entry in the competition for space tourism dollars.
Isaacman is the third billionaire to launch this summer, following the brief space-skimming flights by Virgin Galactic’s Richard Branson and Blue Origin’s Jeff Bezos in July. Only 38, Isaacman made his fortune from a payment-processing company he started in his teens.
Joining Isaacman on the trip dubbed Inspiration4 is Hayley Arceneaux, 29, a childhood bone cancer survivor who works as a physician assistant where she was treated – St Jude Children’s Research Hospital in Memphis, Tennessee. Isaacman has pledged $100m out of his own pocket to the hospital and is seeking another $100m in donations.
Arceneaux became the youngest American in space and the first person in space with a prosthesis, a titanium rod in her left leg.
Also along for the ride are sweepstakes winners Chris Sembroski, 42, a data engineer in Everett, Washington, and Sian Proctor, 51, a community college educator in Tempe, Arizona.
Once opposed to space tourism, NASA is now a supporter.
“Low-Earth orbit is now more accessible for more people to experience the wonders of space,” tweeted NASA Administrator Bill Nelson, who was a congressman when he hitched a ride on a space shuttle decades ago.
Researchers create a novel method of bioprinting neuron cells – Medical Xpress
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 neurons, 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, drug testing 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 human organs 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
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.
