FYI to everyone: there are several fake “ESA Official” YouTube channels running deepfaked Elon crypto scam streams that claim to be “Ariane 6 Launch Stream”.
They’re nothing new, but sharing in case anyone hasn’t seen it before. Those aren’t real streams!
It’s fine, both of the last two US Rovers are powered off RTGs and several of the deep space probes run off RTGs also. For low Earth orbit and stuff closer to the sun it doesn’t make sense but going further out and especially in a place like Mars where solar panels are prone to being covered in dust an RTG power source makes sense.
Seems like they might be between ground stations right now. Haven’t seen live video from the upper stage for a few minutes. Telemetry still looks good though.
The tech-demo phase of Ariane 6 is still in progress but has shown an unexpected result which will only affect the end of the mission.
On the webcast, they stated that the Auxiliary Propulsion Unit (APU) switched off shortly after it it powered up after SECO-2. Without the APU, they have no way to settle the propellants in the tanks, and thus can’t reignite the upper stage for the final burn.
From the live camera feed, it looks as though the upper stage was spinning, so there may have been some loss of control as well.
“We are obviously not surprised by these results… it would have been extremely concerning to find out that Earth was not habitable! But they indicate that MAJIS and SWI will work very successfully at Jupiter, where they will help us investigate whether the icy moons could be potential habitats for past or present life.”
The first ESA instrument to land on the Moon has detected the presence of negative ions on the lunar surface produced through interactions with the solar wind.
The European team working with the Negative Ions at the Lunar Surface (NILS) instrument confirmed the success of this scientific mission that flew to the far side of the Moon aboard the Chang’e-6 spacecraft.
The discovery of a new component of plasma at the surface of the Moon opens a new window for space physics and for human and robotic missions in an era of renewed lunar exploration.
