NASA and SpaceX signed an unfunded Space Act Agreement Thursday, Sept. 22, to study the feasibility of a SpaceX and Polaris Program idea to boost the agency’s Hubble Space Telescope into a higher orbit with the Dragon spacecraft, at no cost to the government.

The gas giant Jupiter is coming the closest it has come to Earth in 59 years this Monday and will be particularly visible because it coincides with another event called opposition.
When in opposition, a planet is on the opposite side of Earth from the sun, so you could draw a straight line from the sun to Earth to Jupiter, all in alignment. Jupiter’s opposition happens every 13 months. Looking from the Earth, when the sun sets in the west, Jupiter will rise in the east, directly opposite. During opposition, planets appear at their biggest and brightest.
Separately, Jupiter is coming closer to Earth than it has since 1963. Because of Earth’s and Jupiter’s differing orbits around the sun, they don’t pass each other at the same distance each time. When it’s closest on Monday, Jupiter will be about 367 million miles from Earth, according to NASA. At its farthest, it’s 600 million miles away.

Issac Arthur play list.
SFIA looks at uses for black holes ranging from spaceships to artificial worlds to escaping the Heat Death of the Universe.
Anyone who’s looked into high-voltage experiments is likely familiar with ion lifters — spindly contraptions made of wire and aluminum foil that are able to float above the workbench on a column of ionized air. It’s an impressive trick that’s been around since the 1950s, but the concept has yet to show any practical application as the thrust generated isn’t nearly enough to lift a more substantial vehicle.
It’s a bit early to suggest that [Jay Bowles] of Plasma Channel has finally found the solution to this fundamental shortcoming of electrostatic propulsion, but his recently completed multi-stage ion thruster certainly represents something of a generational leap for the technology. By combining multiple pairs of electrodes and experimentally determining the optimal values for their spacing and operational voltage, he’s been able to achieve a sustained exhaust velocity of 2.3 meters per second.
While most ion thrusters are lucky to get a piece of paper fluttering for their trouble, [Jay] demonstrates his creation blowing out candles at a distance of a meter or more. But perhaps the most impressive quality of this build is the sound — unlike most of the experimental ion thrusters we’ve seen, the air flowing through this contraption actually makes an audible roaring sound. When the 45 kilovolt supply voltage kicks in it sounds like a hair drier, except here there’s no moving parts involved.
The list of things that interest Elon Musk ranges from space travel to easing Los Angeles’ infamous traffic.
One thing that doesn’t make the cut? Patents.
The 51-year-old entrepreneur recently appeared on CNBC’s “Jay Leno’s Garage” to give the former “Tonight Show” host a tour around the SpaceX Starbase facility in Texas.
Florida’s “silent” flying dish-rack, powered by ionic propulsion, is on track for commercial rollout in 2024, according to Undefined Technologies, which has released new outdoor flight test video. We remain curious, but unconvinced it’ll be viable.
The “Silent Ventus” drone doesn’t use propellers to fly. Instead, its entire broad structure creates two stacked grids of electrodes, designed to create high-voltage electric fields that can ionize the oxygen and nitrogen molecules in the air, freeing electrons to give them a positive charge, and then propelling these downward to create an “ionic wind” that can produce thrust.
It’s not new; ionic propulsion has been used in space, and as we pointed out when we first saw the Silent Ventus drone project, for a few very small-scale terrestrial projects as well, one of which was used to levitate Orville the mouse in 2003. Undefined says its “Air Tantrum” technology yields “higher levels of thrust, up to 150% compared to current ion thruster technologies.”
The hotel giant will help “reimagine the human experience in space, making extended stays more comfortable”.
In Stanley Kubrick’s landmark film, 2001: A Space Odyssey, a Hilton hotel is seen orbiting the Earth. More than 20 years later, sci-fi fantasy has become reality.
Hotel behemoth Hilton has signed on to design astronaut facilities for an Earth-orbiting commercial space station Starlab, Voyager Space, a global leader in space exploration, announced. Starlab is currently under development by Voyager Space Holdings and Lockheed Martin, who first announced the orbiting complex in 2021.

Imagine if we could get to Mars in 40 days instead of seven months! It could happen if we used plasma rockets, which travel at 34 miles per second. But how do we make this a reality?
SpaceX has completed a record-breaking test of a Starship booster and rolled a newer Super Heavy prototype to the launch pad just hours apart.
Almost six weeks after SpaceX began Super Heavy Booster 7’s static fire test campaign, the company has broken new ground by simultaneously igniting seven Raptor engines at once. A matter of hours later, confirming SpaceX CEO Elon Musk’s plans in real time, the company transported a second Super Heavy prototype (Booster 8) from the factory to the launch pad, where it joined Booster 7.
According to Musk, those rockets will soon switch places, ensuring that no time is wasted while SpaceX continues to gradually work towards Starship’s first orbital launch attempts.
