The Ascent Abort-2 test flight launched on July 2, 2019, from Cape Canaveral Air Force Station, Fla. The mission was to test the launch abort system aboard NASA's Orion capsule so astronauts will be kept safe if an anomaly occurs during the return to Earth from space.

The launch abort system of the National Aeronautics and Space Administration's (NASA) Orion capsule descends to the ocean after the Ascent Abort-2 launch on July 2, 2019, at Cape Canaveral Air Force Station, Fla. The AA-2 mission was to test the abort system that will keep astronauts safe should an anomaly occur upon re-entering the earth from space. (U.S. Air Force photo by James Rainier)

Whoever authored this paragraph clearly didn't reflect too much on the name "Launch abort system". It's not used during the return to Earth, but rather if something goes wrong during launch. It is in fact discarded on the way up if everything goes well.

Real torchship???? Like an "Epstein Drive" from Expanse Series?


Meet the Flow-Stabilized Z-Pinch Fusion. Btw, it's one of the most promising concepts for Fusion for energy production also!

https://www.researchgate.net/publica...Fusion_Concept

Lawrence Livermore Lab providing opinion on it (the fusion device, not specifically the propulsion method)
https://pls.llnl.gov/news/sustained-...fusion-z-pinch


Its being funded by ARPA-E

The plasma in a flow Z-pinch wouldalready be moving axially, fusing, and releasing a tremendous amount of nuclear energy.The end of the Z-pinch can be left open to allow the escape of the energetic plasma. Specificimpulses in the range of 10^6s and thrust levels of 10^5N are possible.
10 million Isp and 1 million Newtons Thrust!!

And in a COMPACT lightweight concept.

This can achieve 1g acceleration in a small (100 tons) spacecraft.

Vega Rocket Suffers 'Major Anomaly' During Launch of UAE Satellite

A European Vega rocket suffered a "major anomaly" while launching a satellite for the United Arab Emirates late Wednesday (July 10), leading to the loss of the rocket and its payload, according to Arianespace, which built the booster.

The Vega rocket launched the FalconEye1 Earth-observation satellite for the United Arab Emirates (UAE) from the Guiana Space Center in Kourou, French Guiana. Liftoff occurred at 9:53 p.m. EDT (10:53 p.m. local time, or 0153 GMT July 11). The nighttime liftoff was a dazzling sight, but then something went very wrong.

"About 2 minutes after liftoff, around the Zefiro 23 ignition, a major anomaly occurred, resulting in the loss of the mission," said Luce Fabreguettes, Arianespace's Executive Vice President of Missions, Operations and Purchasing, in a televised statement just after the failed launch.

Japan Makes History as Hayabusa2 Attempts to Collect Underground Samples From Asteroid

Quote:
Earlier today, Japan’s Hayabusa2 may have become the first probe in history to collect material from beneath the surface of an asteroid—a mission that could yield important new insights about the early stages of our solar system. The attempt alone is an exciting achievement, but we won’t know for sure whether the probe successfully gathered samples until it returns to Earth next year.

“From the data sent from Hayabusa2, it has been confirmed that the touchdown sequence, including the discharge of a projectile for sampling, was completed successfully,” the Japan Aerospace Exploration Agency (JAXA) announced in a press release issued earlier today.

The probe performed its brief touchdown at 10:06 a.m. Japan time and is functioning normally, according to JAXA.
