SpaceX CEO Elon Musk reiterated his support for terraforming Mars, as part of his long-term goal to make humanity into a multi-planetary species.

On Sunday, the day after SpaceX’s all-civilian mission to orbit returned to Earth, the CEO took to Twitter to suggest that he’s still got his sights set on the long-term goal of making Mars a more Earth-like world. In response to a post about Mars temperatures, which claimed the average surface temperature is around minus 63 degrees Celsius (minus 82 degrees Fahrenheit), Musk responded: “Needs a little warming up.”

The comments hint at Musk’s goal, stated multiple times over the years, that he would like to transform the planet’s atmosphere to make it more hospitable to human life. It forms part of his overall goal with SpaceX: reduce spaceflight costs, use it to establish permanent human presences elsewhere in space, and transform humanity into a multi-planetary species.

SpaceX CEO Elon Musk helped achieve the St. Jude Children’s Research Hospital fundraising goal of the Inspiration4 spaceflight, just hours after his company returned the crew from orbit.

The main goal of the Inspiration4 mission, which launched on Wednesday and splashed down on Saturday, was to raise $200 million for St. Jude.

Inspiration4 commander Jared Isaacman, a billionaire entrepreneur who purchased the flight from SpaceX, donated $100 million personally to St. Jude. The Inspiration4 mission had raised another $60.2 million in donations, before Musk pledged to contribute $50 million himself – pushing the campaign’s total raised to more than $210 million.

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein’s theory of general relativity would require vast amounts of hypothetical particles and states of matter that have “exotic” physical properties such as negative energy density. This type of matter either cannot currently be found or cannot be manufactured in viable quantities. In contrast, new research carried out at the University of Göttingen gets around this problem by constructing a new class of hyper-fast ‘solitons’ using sources with only positive energies that can enable travel at any speed. This reignites debate about the possibility of faster-than-light travel based on conventional physics. The research is published in the journal Classical and Quantum Gravity.

The author of the paper, Dr Erik Lentz, analysed existing research and discovered gaps in previous ‘warp drive’ studies. Lentz noticed that there existed yet-to-be explored configurations of space-time curvature organized into ‘solitons’ that have the potential to solve the puzzle while being physically viable. A soliton — in this context also informally referred to as a ‘warp bubble’ — is a compact wave that maintains its shape and moves at constant velocity. Lentz derived the Einstein equations for unexplored soliton configurations (where the space-time metric’s shift vector components obey a hyperbolic relation), finding that the altered space-time geometries could be formed in a way that worked even with conventional energy sources. In essence, the new method uses the very structure of space and time arranged in a soliton to provide a solution to faster-than-light travel, which — unlike other research — would only need sources with positive energy densities.

A type of thruster being tested in a NASA lab could help scientists unlock the key to making a ‘Star Trek’ inspired warp drive enabled starship.

In 2,019 the Israeli Beresheet spacecraft crash-landed on the Moon. Along for the ride were thousands of tardigrades.

This glass dome is where the toilet is, crew member Jared Isaacman, who purchased the four seats for the mission, told Insider’s Morgan McFall-Johnsen in July.

SpaceX CEO Musk tweeted on Thursday that he had spoken with Isaacman, Hayley Arceneaux, Sian Proctor, and Chris Sembroski, the four people on board.

“All is well,” Musk said in his Twitter post. He didn’t mention what was discussed.

JAXA tested a rotating detonation engine (RDE) in a sounding rocket and it’s been a success. What does this mean for the future of deep space exploration?

The selected companies will develop lander design concepts, evaluating their performance, design, construction standards, mission assurance requirements, interfaces, safety, crew health accommodations, and medical capabilities. The companies will also mitigate lunar lander risks by conducting critical component tests and advancing the maturity of key technologies.

The work from these companies will ultimately help shape the strategy and requirements for a future NASA’s solicitation to provide regular astronaut transportation from lunar orbit to the surface of the Moon.
