JUICE Set for Third Earth Gravity Assist on September 28

ESA plans for the JUICE spacecraft to fly past Earth on September 28 at a closest distance of about 8,640 kilometres. The gravity assist is expected to bend the trajectory by roughly 20 degrees and add about 3.5 kilometres per second.

Hubble Reveals the Out-of-Sync Structure of Galaxy NGC 4698

A new Hubble image of NGC 4698, about 55 million light-years away, shows a central bulge extending nearly perpendicular to the outer disk. Stars and gas near the centre also rotate differently from the rest of the galaxy.

NASA Revises Swift Boost Mission After LINK Attitude-Control Issue

NASA and Katalyst Space say the LINK spacecraft will no longer attempt to capture and raise the orbit of the Swift observatory because of an ongoing attitude-control issue, though rendezvous and proximity operations are still planned.

ESCAPADE’s Gold completes its second correction before the Mars transfer

Rocket Lab’s January 7, 2026 ESCAPADE log confirms Gold completed its second trajectory correction on January 6 with a 97.7-second burn. It followed a short December firing and sends Gold past the Sun–Earth L2 region into a loiter trajectory. Earlier 2025 launch and Blue manoeuvres remain background. A November 2026 Mars transfer and September 2027 arrival were then plans, not achieved orbit insertion. The article uses the confirmed burn rather than an older preliminary duration. NASA and UC Berkeley’s twin mission aims to study atmospheric escape; later manoeuvres and science results require separate evidence.
