On 19–20 August 2024, Juice successfully completed a world-first lunar-Earth flyby, with flight controllers guiding the spacecraft first past the Moon, then past Earth. The gravity of the two changed Juice’s speed and direction, sending it on a shortcut to Jupiter via Venus.
The closest approach to the Moon was at 23:15 CEST on 19 August, deflecting Juice towards a closest approach to Earth just over 24 hours later at 23:56 CEST on 20 August. In the hours before and after both close approaches, Juice’s two monitoring cameras captured photos, giving us a unique ‘Juice eye view’ of

Billionaire Jared Isaacman could make history for all the right reasons during his Polaris Dawn mission when the hatch opens on a SpaceX Crew Dragon and he ventures out into the vacuum of space.
He's sold on its safety, especially the sheer amount of development time in the new extravehicular activity suits all four members of the crew will have to wear during what would be the first commercial space walk in history.
"I mean, an absolutely extensive amount of time has gone into it," he said during a press conference after arriving to KSC last week. "It is rightfully. Why would it be the riskiest part? Because you're throwing away all the safety of your vehicle, right? And it now comes down to your suit becomes your spaceship."
Isaacman and crewmates Scott Poteet, Sarah Gillis and Anna Menon are set to launch in the Crew Dragon Resilience atop a Falcon 9 rocket from KSC's Launch Pad 39-A early Tuesday, targeting liftoff at 3:38 a.m. Eastern time during a roughly four-hour window.
Poteet is a former Air Force pilot, while Gillis and Menon are SpaceX employees as the Polaris Program, which will feature up to three spaceflights including this one, is a partnership between Isaacman and Elon Musk's company to push the boundaries for commercial space.

NASA has taken the next critical step in preparing for the launch of its first crewed Artemis space mission, the agency announced Thursday.
On Wednesday, crews rolled out a key piece of space flight hardware, a cone-shaped launch vehicle stage adapter, that will connect the rocket's core stage to its upper one, protecting the engines that will help propel the Artemis II in a test flight Mynaric ousts CEO amid production troubles

China proposes magnetic launch system for sending resources back to Earth
Monday, 26 August 2024 16:16 Write a comment
In his famous novel "The Moon is a Harsh Mistress," Robert A. Heinlein describes a future lunar settlement where future lunar residents ("Loonies") send payloads of wheat and water ice to Earth using an electromagnetic catapult.
In the story, a group of Loonies conspire to take control of this catapult and threaten to "throw rocks at Earth" unless they recognize Luna as an independent world. Interestingly enough, scientists have explored this concept for decades as a means of transferring lunar resources to Earth someday.
Given that space agencies are planning on sending missions to the moon to create permanent infrastructure, there is renewed interest in this concept. In a recent paper, a team of scientists from China's Shanghai Institute of Satellite Engineering (SAST) detailed how a magnetic launcher on the lunar surface could provide a cost-effective means of sending resources back to Earth.
