“The positive conclusion of our preliminary design review marks a major milestone in SABRE development,” Mark Ford, heading ESA’s Propulsion Engineering section, said in a statement. “It confirms the test version of this revolutionary new class of engine is ready for implementation.”

There’s just one problem. Well, okay, several.

SpaceX is giving Boca Chica Village homeowners more time to consider its buyout offer and is agreeing to reappraise the properties after complaints that the original appraisals were too low.

Last month, the Hawthorne, Calif.-based rocket company sent property owners a letter dated Sept. 12, offering them three times the value of their homes based on appraisals SpaceX had commissioned. The deadline for accepting the offer was two weeks from the date of the letter and the offer was non-negotiable.

SpaceX said it wants to buy the properties due to a greater-than-anticipated disruption to residents and property owners as development of the company’s Mars rocket, Starship, gains steam.

If SpaceX wants its massive next-generation spacecraft to reach the moon and planets beyond, CEO Elon Musk says it’ll need to be refueled in orbit around Earth – and NASA wants to know more.

Now in the prototype and early test flight phase, Starship is a stainless steel crewed craft that will launch atop a Super Heavy booster. But because of its size and potentially heavy payloads – like dozens or hundreds of astronauts – in the future, it will need to be refueled in orbit around Earth before it begins longer voyages.

SpaceX, Musk said, is developing the technologies necessary to dock two Starships together in orbit – one without much in the way of crew or payloads – and transfer fuel to the one venturing beyond low-Earth orbit.

When Elon Musk announced the launch of SpaceX ($SPACEX) in 2002, comparisons to Jeff Bezos’ Blue Origin ($BLUEORIGIN) surfaced seemingly within seconds, and a private space war was born. As both companies engage in their own space race, and compete for private and government launch contracts, they’ve both been on hiring sprees virtually since the day they were born.

Blue Origin’s head start remains intact, and is manifested in its hiring patterns that have shown the company adding more people at any one time than SpaceX. But that lead, at least according to trends we’re now seeing with enough data, may end in the next year or two.

SPACEX STARSHIP is Elon Musk’s ambitious plan to carry crew and cargo to the Moon, Mars and beyond. Now, the SpaceX CEO has revealed significant tweaks to the Starship’s extraordinary design.

Michio Kaku declared that he found Einsteins theory breaks down at a certain point and was attacked by science. Here NASA has proof that Einsteins theory of nothing traveling faster than the speed of light is wrong, and again old school wants Einstein to still be followed. That is what I have explained to Physiologists about yes, Physiolgy.

A NASA scientist has questioned whether Albert Einstein’s theories over space were inaccurate after the Hubble telescope recorded an object travelling five times the speed of light.

Space bacteria — they’re tiny, invisible, and potentially harmful; even if no one is sure that they actually exist. But for most of the Space Age, NASA and other agencies have treated the possibility of pathogens from space carefully, both during our exploration of other worlds and because of the havoc they could conceivably wreak on Earth. Nowadays, though, there’s a new factor: Elon Musk.

The billionaire entrepreneur dreams of settling thousands of humans on the planet Mars and, oh yeah, he happens to own a rocket company that is slowly building the capability to do so. Musk and other leaders in the commercial space industry are looking at opening up previously unexplored possibilities — asteroid mining, private space stations, package delivery to the moon’s surface. Laudable as these goals are, they are also forcing governments around the world to rethink their space regulations and consider whether they’re up to these impending challenges.

As ever more players enter the space arena it’s time to make sure that everybody is following the best planetary protection practices. Exploring the universe should happen for the benefit of all, including future generations.
