SpaceX-Backed Flying Car Startup Gets FAA Nod
Posted by Genevieve Klien in categories: space travel, sustainability
Pre-orders for a “flying car” have soared in recent months leading industry experts to question how close we are to small passenger vehicle flight. Alef Aeronautics, a company backed by Space-X, specialising in the production of flying cars, has achieved 2,850 pre-orders for its electric vertical take-off and landing (eVTOL) vehicle. The firm is backed by Tesla investor and venture capitalist Tim Draper, which has helped draw attention. Based in San Mateo, California, Alef Aeronautics is allowing customers to pre-order its two-seater flying car, the Alef Model A, online with a $150 deposit. Customers are allowed to withdraw the deposit at any time to cancel the pre-order.
The car is expected to be priced at around $300,000 when it becomes commercially available, which gives the company an order value of over $850 million to date. Jim Dukhovny, Alef’s CEO, stated: “As of today we have a little bit more than 2,850 pre-orders with deposits down, which makes it the bestselling aircraft in history, more than Boeing, Airbus, Joby Aviation and most of the eVTOLs combined.”

NASA, SpaceX looking to extend lifespan of Crew Dragon spacecraft to 15 flights
Posted by Genevieve Klien in category: space travel
Crew-8 marks the fifth flight for Endeavour, the maximum number of flights Crew Dragon spacecraft have been qualified for. But this spacecraft, what NASA and SpaceX refer to as the “fleet leader,” could potentially prove itself worthy of more flights — possibly many more. According to NASA officials, Crew Dragon might be able to fly up to 15 times, depending on the results of a requalification campaign the agency and SpaceX will undertake this year and next.

During a press briefing on Feb. 28 to discuss the Crew-8 mission, Steve Stich, program manager for NASA’s Commercial Crew Program, said SpaceX is currently performing qualification tests of “every single” component on the Dragon spacecraft in order to determine how many flights the spacecraft might be capable of making.

SpaceX Dragon Endeavour With Crew-8 Aboard Docks to International Space Station
Posted by Natalie Chan in category: space travel
NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin arrived at the International Space Station, as the SpaceX Dragon, named Endeavour, docked to the complex at 2:28 a.m. EST on March 5 while the station was 260 statute miles over Newfoundland.
Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station conducted standard leak checks and pressurization between the spacecraft in preparation for hatch opening.
The goal of science is to understand and master the Universe around us, but could our skill grow so great that we could learn to warp reality itself?

SpaceX Dragon with Crew-8 Aboard Docks to Station
Posted by Shubham Ghosh Roy in category: space travel
NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin arrived at the International Space Station, as the SpaceX Dragon, named Endeavour, docked to the complex at 2:28 a.m. EST while the station was 260 statute miles over Newfoundland.
Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station will begin conducting standard leak checks and pressurization between the spacecraft in preparation for hatch opening scheduled for 4:13 a.m.
Crew-8 will join the space station’s Expedition 70 crew of NASA astronauts Jasmin Moghbeli and Loral O’Hara, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Furukawa Satoshi, and Roscosmos cosmonauts Konstantin Borisov, Oleg Kononenko, and Nikolai Chub. For a short time, the number of crew aboard the space station will increase to 11 people until Crew-7 members Moghbeli, Mogensen, Satoshi, and Borisov return to Earth.

Cold Chemistry is Different
Posted by Saúl Morales Rodriguéz in categories: chemistry, particle physics, quantum physics, space travel
Experiments demonstrate some of the unusual features of molecular reactions that occur in the deep cold of interstellar space.
Many common small molecules are formed in interstellar space, and their low temperatures are expected to have profound effects on their chemical reactions because of quantum-mechanical effects that are masked at higher temperatures. Researchers have now demonstrated some of these cold chemistry phenomena—such as the effects of molecular rotation and collision energy on reaction rates—in a reaction between a hydrogen ion and an ammonia molecule in the lab. The results, while intuitively surprising at first glance, can be explained by a careful theoretical analysis of the quantum chemistry.
Measuring reaction rates at low temperatures is useful for testing quantum-chemical theory because in those conditions molecules may occupy only a few well-defined quantum states. Such experiments could also offer insights into chemical processes in the cold clouds of gas in star-forming regions of interstellar space, where many of the simple molecules that make up solar systems are formed. But low-temperature experiments are difficult, especially for charged atoms and molecules (ions), because they are very sensitive to stray electric fields in the environment, which accelerate and heat up the ions.
