NASA's Artemis 1 moon rocket passes crucial fueling test despite leak

If checks in the VAB go smoothly, it's possible NASA will target the schedule's earliest long mission opportunity, which would kick off with a launch on Aug. 29. However, a long mission window lasting five consecutive days exists between Sept. 2 and Sept. 6, and may serve as a more favorable option. In any case, NASA officials are not likely to commit to a launch date prior to SLS inspections in the VAB, which won't begin until later this month.

NASA targeting June 19 for crucial test of Artemis 1 moon rocket

The agency aims to roll the Artemis 1 stack back out to the launch pad on June 6.

NASA plans to take another crack at a crucial fueling test of its Space Launch System (SLS) megarocket on June 19.

NASA will try again to fuel Artemis 1 moon rocket in June as launch slips to August

Artemis 1 will send an uncrewed Orion on a roughly month-long journey around the moon. The mission — the first in NASA's Artemis program of lunar exploration — is designed to ensure that both SLS and Orion are ready for crewed flights.

If all goes well with Artemis 1, Artemis 2 will send astronauts around the moon in 2024 and Artemis 3 will land a crew near the lunar south pole in 2025 or thereabouts.

SpaceX's Starship will be ready for 1st orbital flight in July, Elon Musk says

"Starship will be ready to fly next month. I was in the high bay & mega bay late last night reviewing progress," the billionaire entrepreneur said via Twitter today (June 14). 

"We will have a second Starship stack ready to fly in August and then monthly thereafter," Musk added in another tweet.

Hardware readiness won't guarantee a July Starship flight, however; SpaceX still needs to secure a launch license from the U.S. Federal Aviation Administration (FAA). And getting one won't necessarily be easy;

I wonder why something that as expensive as bitcoin can suddenly become 3 times less expensive.
Because if there is certain cryptoexchange and it sells bitcoin for $60,000 and there were people willing to buy it for such price, why would price suddenly become less? The only reason to me can be people suddenly become less interested in buying bitcoin and then why would they suddenly become less interested? I personally suspect real reason is just some regulations - rules exchanges follow and not really actual people lost interest to buy bitcoin. I think bitcoin is just returning to its normal price not inflated by government influence. #cryptocurrency #bitcoin

China's New Space Station Will Be Powered by Ion Propulsion System

This decades-old technology could slash journey times to Mars from eight months to 39 days.

Such thrusters have been used since the 1970s; however, the Tiangong's core module is set to become the first crewed spaceship propelled by ion drives. China is betting big on ion thrusters and intends to develop them on a far greater scale for its deep-space missions.

The space station’s core Tianhe module, which will welcome its first astronauts later this month if all goes to plan, is propelled by four ion thrusters, which utilize electricity to accelerate ions as a type of propulsion.

South Korea ‘successfully’ launches homegrown Nuri space rocket

South Korea has successfully launched its first domestically developed space rocket, the science ministry said, in the second attempt months after a launch last October failed.

The Korea Satellite Launch Vehicle II, a liquid fuel rocket informally called Nuri, lifted off from the launch site in Goheung at 4pm on Tuesday.

The three-stage Nuri rocket has been a decade in development at a cost of 2 trillion won ($1.5bn).

It weighs 200 tonnes and is 47.2 metres (155 feet) long, fitted with a total of six liquid-fuelled engines.

NASA's Artemis 1 moon mission passes crucial fueling test despite leak

The Artemis 1 team managed to fully fuel the Space Launch System rocket.

NASA's Artemis 1 moon mission completed a crucial preflight milestone today (June 20), wrapping up a two-day set of tests known as a wet dress rehearsal.

Not everything went perfectly smoothly. The Artemis 1 team noticed a hydrogen leak during fueling today, and they intentionally "masked" data associated with the issue to let the countdown continue. (During an actual launch countdown, such data would have raised red flags, NASA officials said.) This change meant the countdown was halted at T-29 seconds before "liftoff," instead of T-9 seconds as originally planned.

NASA says its ready for a fourth attempt to fuel the massive SLS rocket

This will be NASA's fourth attempt to load the SLS rocket's first and second stages with liquid hydrogen and liquid oxygen and go deep into a countdown toward launch before ending the test at T-10 seconds. The space agency plans to call its team of engineers and technicians to their stations on Saturday evening and begin fueling operations on Monday morning, June 20.
