Was out with a bunch of fellow geologists, who all got a kick out of looking at Saturn and the moon. Was only taking pictures with my phone, and so didn’t get a good shot of Saturn, but thought this one of the moon was nice.
Super cool photo, but does this technically count as astronomy? Isn’t astronomy “a camera on (usually) on earth, pointed up into space”, not the other way around?
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that...
From my brief look into the topic, interferometry tech is not quite there yet, but might be in the next few decades. Interferometry is more difficult with shorter wavelengths.
Watch the launch of @CopernicusEU#Sentinel2C on #VV24, the last Vega flight from Europe’s Spaceport, live on #ESAwebTV on 4 September from 02:30 BST/03:30 CEST (liftoff scheduled at 02:50 BST/03:50 CEST).
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.
