OK, I'm ready for this! In 🇯🇵 Prime Minister’s Office with Mr. Noriyuki Shikata, Cabinet Secretary for Public Affairs. Standing as a proud #European & got informed on #G7 & Japan Priorities. I am optimistic about #Japan’s new foreign policy for the following reasons. #Thread

Vous avez tous entendu parlé des méga-trends. Ces tendances de fond qui ont un impact significatif sur l'économie, la société et l'environnement.
Les #investisseurs qui sont en mesure de les détecter peuvent tirer parti de ces tendances pour maximiser leur performance.

Kayrros data show #CO2 emissions levels from #Europe and #China started dropping last month, and have reached levels unseen since the worst of the Covid pandemic. (1/6)
Although this is good news from a #climate perspective, it is a worrying sign that the global #economy is coming under serious strain from the effect of high #energy prices and supply chain issues. (2/6)
In #China, overall CO2 #emissions have been in a counter-seasonal decline and cement production has dropped to levels normally unseen at this time of year. (3/6)

Exclusive: More than 10yrs after it was launched, #MeghaTropiques, @isro & @CNES joint weather modelling satellite that was studying water cycle & energy exchanges in the tropics has reached what’s called “end of mission”. 1/n

The satellite, which was launched in October 2011 and initially estimated to have a life of five years has worked for five-years-and-six-months more than initial estimations and sent in at least 5TB of raw data which has yielded around 30TB of data sitting on various servers. 2/n
A senior Isro scientist said: “As on date, the satellite still has 120kg of fuel and end of mission is also not because of failures in communication, solar panels or any other systems or because we lost communication. All of those are still working.” 3/n

Starlink is a constellation of broadband satellites that SpaceX is assembling in low earth orbit to provide internet access to most of the world.
This mission to provide high-speed internet to remote locations has been widely commended, but it isn't free from controversy. (2/5)

As over 6000 #satellites orbit Earth, many astronomers have pointed out the increasing chances of collision with an aircraft or another satellite. If such a collision were to occur, the loss would be astronomical!

Happy first day of #BlackHistoryMonth! To celebrate, we'll periodically take time to honor the brilliant Black minds that have contributed to our field over the years. A thread:
First up in our series: @6Gems, who founded @BlackGirlsCode after noticing the severe underrepresentation of minorities in the startup world. Bryant's nonprofit has enabled many young black girls to create meaningful work & go on to become leaders in their communities. #BHM2022
@6Gems @BlackGirlsCode Katherine Johnson was a human computer whose calculations were essential to @NASA's Project Mercury, Apollo 11, and more. When the space program switched to digital computers, Johnson helped confirm the accuracy of their calculations.
2021 has been exciting! We’ve signed our first customer for our maiden flight, reached crucial milestones in our launcher development & our #community grew rapidly. So we want to quickly introduce ourselves to our new followers and recap with the long-time #supporters ⬇️ 1/12
RFA was founded in 2018 to disrupt the #NewSpace industry and match the emerging demand for launch opportunities for small #satellites by providing launch services that are reliable, highly customizable, low-cost and deliver the payloads precisely to the desired orbit. 2/12
Our launch vehicle #RFAONE is a 30m high and 2m wide 3-staged rocket, launching satellites of up to 1350 kg into polar orbits/up to 450 kg into GTO. The main structural elements consist of tanks made of a special stainless steel, which becomes very tough at #cryogenic temp. 3/12
We're nearing the end of 2021 & what a year it's been! I said 2021 would be the year of the public cloud in telco. Was I right, or not?

While there are lots of problems with FB, Insta & co, Meta's newest project, the metaverse, sound super exciting! Looks like Meta is putting lots of money towards Oculus' #quest to build long-distance-presence solutions.

2 reasons why the Metaverse has potential:
1. Most importantly, remote work is here to stay. But for hybrid work settings (i.e. some in the office, some remote) there is no good solution yet. Metaverse intends to solve that.

2. Many of today's issues require coordination on a global scale. Think of the #ClimateCrisis, the #BiodiversityCrisis, overcoming #NeoColonialism and #inequality, et cetera. The Metaverse promises to make such coordination comfortable, natural and effective.
🙅♂️"Pas de retombée" ... ça dépend de l'orbite.
La plus encombrée est l'orbite basse. À cette altitude, les objets vont effectivement très vite. Cependant, ils subissent une trainée due à des résidus d'atmosphère, ce qui le fait tomber.

Did you know that Geosynchronous #satellites do THE WAVE each day?
I created this animation of movement over a full day to show you.

Now you also know why the @SpaceForceDoD wants Navy ranks...it's an ocean out there.... ;-)
As people ask me what causes this daily wave in the geosynchronous belt: it is a tidal effect due to solilunar perturbations on the satellite orbit.
This also causes a long-term (55 year) oscillation of the orbital inclination in GEO between 0 and 15 degrees.
