Success! On Monday, the #JUICE mission successfully completed a flyby of #Earth. This was a gravity assist, designed to increase the spacecraft’s speed and alter its trajectory as it makes a winding trip to #Jupiter. It will arrive in 2031. 🛰️🌎

NASA's MESSENGER Satellite Captures Spectacular Color Mosaic of Mercury - From Goddard Space Flight Center - https://flic.kr/p/9uD599
NASA image acquired: January 14, 2008 This spectacular color mosaic shows the eastern limb of Mercury as seen by MESSENGER as the spacecraft departed the planet following the mission's first Mercury flyby in January 2008. The colors of this image are not those that would be seen by the human eye but instead convey information about the distribution of different rock types on Mercury's surface. The different rock types result in subtle color variations across all of the 11 WAC narrow-band color filters. The Caloris basin, visible as a large bright yellow circular area in this image due to its infill of volcanic plains, dominates the northern region. A similar image was published in Science magazine in July 2008, but it only covered the northern half of the region shown here. To create this larger color mosaic, MESSENGER Science Team members had to also devise a method to deal with scattered light in the 11 different WAC filters. MESSENGER has obtained color imaging at this resolution only for the portions of Mercury seen on departure from Mercury flybys 1 and 2. As spectacular as this color image is, it is just a taste of what is yet to come. In 2011, MESSENGER will become the first spacecraft ever to orbit Mercury and begin a year-long observing campaign that includes imaging all of Mercury's surface in color at an average resolution of about 1 kilometer/pixel (0.6 miles/pixel), a resolution that is about a factor of three better than this already impressive image. Cre...

One year ago. Deep Space Station 15, one of the 34-meter antennas at NASA's Goldstone Deep Space Communications Complex. It was first built to support Voyager 2's Uranus flyby.

The rain stopped just long enough reveal the antenna and the setting Moon

Wrist shot from the point. #Texier trying to do a flyby, but is late. #Bobrovsky just picked it up late.

Who heard the whisper? TinyGS — a crowdsourced net of hobbyists with $30 receivers and small antennas on their balconies. Amateurs on multiple continents caught the packets live and decoded them in near real-time. A planetary flyby architecture, received by volunteers.

It's only been visited by a probe once, and that was a flyby. Since flybys are just snapshots, they give waaaay less info than orbiters. And Uranus compounded the problem: it spins on its side, and its pole was pointed at the sun. That means half of it was in darkness the entire time, and the same

Did more radar work! In this flyby, the other ship has its radar on, so we get big signals from each other. At the end of the clip, the ship is being masked out a little bit by the big asteroid. I added 3 'radar cross section' curves to objects, so maybe stealth ships in future? #gamedev #UE5

4-panel comic. (1) April 2023: [JUICE space probe flying away from Earth] FROM EARTH: *JUICE* is en route to explore the icy moons of Jupiter! JUICE: *Wheee!* (2) August 2024: [JUICE flying past Earth] JUICE: ...So which planet was I visiting again? I got distracted. FROM EARTH: Jupiter! JUICE: Right, OK. (3) September 2026: [JUICE flies past Earth again] JUICE: Is Jupiter the one with all the rings? Or... FROM EARTH: No, the big one near it. JUICE: Got it! (4) January 2029: [JUICE returning to fly past Earth again] JUICE: And *which* moons am I looking at? FROM EARTH: Oh my *god*. FROM EARTH: Now I get why we budgeted for so many Earth flybys.

Perhaps it should be said that flybys serve the purpose of getting speed. But I didn't see the Venus flyby.

Earth provided gravity assistance to slingshot the European Space Agency’s Jupiter Icy Moons Explorer (Juice) spacecraft toward the Jupiter system. The SwRI-led Ultraviolet Spectrograph (UVS) instrument is one of 10 instruments aboard Juice.

Successful Earth flyby improves Juice’s course to Jupiter
The European Space Agency’s Jupiter Icy Moons Explorer (Juice) skimmed the very outer edge of Earth’s atmosphere on 28 September, using the gravity of our home planet to alter its route to Jupiter using very little fuel.

recently i started a new ksp science mode playthrough with Principia (n-body physics mod) and Sol (irl solar system mod) and its been a very fun and different experience

KSP screenshot of a probe having just flew past the Moon, with the Moon and Earth in the background. KSP screenshot showing a probe in low Earth orbit above clouds at sunset.

Seriously, a single flyby? We're not even sure if it's really an ice giant? Let's put the ketamine down, stop masturbating about Martian cities, and get on this. Orbit the thing. Study its moons and magnetic fields in detail. Send probes into its atmosphere. C'mon already.

I was in LA during the 1992 LA riots and aftermath. There is nothing more disconcerting than sitting in a college classroom, while military helicopters fly by at a low altitude.
