The reusability is a key aspect, as Musk has said each engine needs to be capable of flying up to 1,000 times to support the ambitious operations of Starship. That’s a major challenge; the most re-used engines in space exploration history were the main engines on each Space Shuttle, which flew up to only a few dozen times each. “It’s quite ambitious,” says Dodd. “I don’t know if 1,000 flights is necessarily going to be achievable in the near future. If it lives up to its potential, maybe 1,000 is within the realm of possibility one day.”

SpaceX’s existing engine is called Merlin, which is used on its operational Falcon 9 and Falcon Heavy rockets, but Raptor heralds a significant improvement. One is that it has double the thrust of its predecessor thanks to a much higher pressure, 380,000 pounds of thrust at sea level versus 190,000 pounds, despite being a similar size.

NASA has announced 19 technology partnerships between the agency’s many spaceflight centers and 13 companies, including SpaceX, Blue Origin, and more. This round of Space Act Agreements (SAAs) shows a heavy focus on technologies and concepts that could benefit exploration of the Moon and deep space more generally, including lunar landers, food production, reusable rockets, and more.

Put simply, all 19 awards are great and will hopefully result in tangible products and benefits, but SpaceX has a track record of achievement on the cutting edge of aerospace that simply has not been touched over the last decade. As such, the company’s two SAAs are some of the most interesting and telling, both ultimately focused on enabling Starship launches to and landings on the Moon and any number of other destinations in the solar system. Perhaps most importantly, it signals a small but growing sect within NASA that is willing and eager to acknowledge Starship’s existence and actively work with SpaceX to both bring it to life and further spaceflight technology in general.

One agreement focuses specifically on “vertically land[ing] large rockets on the Moon”, while the other more generally seeks to “advance technology needed to transfer propellant in orbit”, a feature that Starship’s utility would be crippled without. In this particular round of SAAs, they will be “non-reimbursable” – bureaucratic-speak for a collaboration where both sides pay their own way and no money is exchanged. SpaceX’s wins ultimately show that, although NASA proper all but refuses to acknowledge Starship, the many internal centers it is nothing without are increasingly happy to extend olive branches towards the company and its ambitious next-generation rocket.

BEIJING (Reuters) — Beijing-based startup iSpace is planning up to eight commercial rocket launches next year, after last week becoming China’s first privately funded firm to put a satellite into orbit, its executives told Reuters.

This could be used for real hoverboards and hovering spacecraft could float out of atmosphere just like aliens do :3.

The quantum vacuum has fascinated physicists ever since Hendrik Casimir and Dirk Polder suggested in 1948 that it would exert a force on a pair of narrowly separated conducting plates. Their idea was eventually confirmed when the force was measured in 1997. Just how to exploit this force is still not clear, however.

In recent years, a new way of thinking about the quantum vacuum has emerged which has vastly more potential. And today, one physicist describes how it could be used to create propulsion.

NASA selects key commercial partnerships to further its new Moon to Mars strategy.

Today, NASA announced it has selected 12 U.S. commercial companies for 19 partnerships in its crewed Moon to Mars efforts, which kicks off with a planned 2024 Artemis program crewed return to the lunar surface.

The selections entail six key areas for future development as well as a category for other exploration technologies. They are: advanced communications, navigation and avionics; entry, descent and landing; in-space manufacturing and assembly; advanced materials; power; and propulsion.

A new ransomware family targeting Android devices spreads to other victims by sending text messages containing malicious links to the entire contact list found on already infected targets.

The malware dubbed Android/Filecoder. C (FileCoder) by the ESET research team which discovered it is currently targeting devices running Android 5.1 or later.

“Due to narrow targeting and flaws in both execution of the campaign and implementation of its encryption, the impact of this new ransomware is limited,” ESET’s researchers found.
