Geotandem: Exploring the subsurface of Mars using geodetic data Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the s...

⚒️🧪 We (blog editors of geodesy, geodynamics and tectonics, and our lovely authors) got together and made these Geotandem posts! All blogs are linked to each other. So what are you waiting for? Explore gravity field, tectonics and geodynamics of Mars here! Ours is written by @broodt.bsky.social

Boven Lille!

Net melding gemaakt op: fireballs.imo.net/members/imo/... for science 😁

Already did that 😁 Het bewoog van Oost naar West.

@marcolangbroek.bsky.social: Net terugkeerend object gezien, mooie groene streak(5-10 sec) met aan het eind wat afbrekende stukken. Ten Zuiden van Delft rond 17:30 +- 30 sec. Heel gaaf! Misschien iets te zien op de cameras?

You want to borrow one from the rooftoplab 😁

Congratulations! Well deserved!!

Finally saw the Kater reversible pendulum in real life at the Teyler museum!!! Writing a piece on it and it is always good to see the equipment with your own eyes. This instrument revealed the shape of the Earth! Gravity reveals!

Probably the last recording (13th of November 08:48 UTC) of Delfi-C3 made by the DopTrack groundstation. Now at 220 km height and will not make it to tomorrow. 🤩

Ja die dus van vanochtend ook gespot, maar was al weer naar originele geswitched, bij de volgende pass

Vandaag gevonden, gister heeft hij niet gezonden op die frequentie. Vandaag de derde pass wel weer gewoon op 145.870 MHz. Dus het is goed om beide frequenties in de gate te houden

Wij zien eigenlijk al dat de frequentie sinds Oktober weer aan het stijgen is, maar dus niet zoveel!

Oh ik zal straks eens in onze data kijken

We can give you the Doppler corrected data 😁

Reflecties (ghost sounds, aliasing) van Rotterdam Airport denken we. Op de nieuwe hardware is niks te zien.

Ja natuurlijk, deze is van vanochtend (rode line is de extracted carrier signal door onze automated processor)

Oh no wait, the day before 🙃

Ja he! 🤩

Here our recording of Delfi-C3 around the same time 😍

Some nice transmissions over Delft yesterday, so Delfi-C3 is still working and sending data down! What a piece of engineering

Nu gaat het snel!

The signal stops constantly, so well done. Its getting old 😃

I love working at the university ❤️ a printed model of the Eros asteroid. I feel like Slartibartfast! Made by one of my students

Yes!

End of Life of the Nayif-1 At DopTrack, we listen to the radio transmission of many cube-sats. One in particular, The Nayif-1 (NORADID: 42017) had captured our attenti...

A new blogpost on the reentry of the Nayif-1 satellite observed by the DopTrack ground station. #tudelft #space #satellites

Hier!!!

We have installed a new antenna in the DopTrack antenna park #tudelft

Verstuurd!

Ja ik moet ook maar eens gaan migreren!

The tasting this weekend was good! #whisky
