THREAD: 1/ We got lots of good questions today on why #FalconHeavy was needed for #USSF44 instead of Falcon 9. You can actually see the reason (yay maths!!!) by comparing the Hotbird 13F & USSF-44 stage separation velocities. Image
2/ This is the center booster's shutdown velocity (2nd stage starting velocity) for USSF-44: ~14,270 km/h. That's 51% of low Earth orbit velocity. Now, compare that to the geostationary transfer orbit (GTO) mission of #Hotbird13F just a few weeks prior... Image
3/ On that GTO mission, the #Falcon9 booster (while still recovered) got the 2nd stage to a starting velocity of ~8,210 km/h. That 2nd stage had quite a lot more work to do (more deltaV needed) to haul the payload into the parking orbit before burning for GTO than USSF-44's did. Image

¡DESPEGUE del #Falcon9! La misión Starlink 4-23 es lanzada desde Cabo Cañaveral con 54 satélites a bordo 🚀🔥
Separación de etapas, ignición de la segunda etapa y separación de la cofia. Todo bien de momento.
Apogeo del propulsor: 134 km.

✈️ BILAN CARBONE : #CASTEX EST VENU SIGNER UN CONTRAT SUR LA «TRANSITION ÉCOLOGIQUE» À NANTES EN JET PRIVÉ !

– Un #Falcon9 rejette 1 500 fois plus de CO2 que le TGV – Image
Le gouvernement n'hésite jamais à parler de «responsabilité écologique» pour taxer les pauvres, tout en protégeant les multinationales ultra-polluantes.
Dans le même registre, Jean Castex prétend défendre le transport en train, plus écolo, mais effectue ses déplacements à bord de Falcon, aux frais du contribuable, y compris pour des petits trajets.

Here we go! @elonmusk is 'virtually' in the building and @mobileworldlive's @SpringhamJustin is our moderator for the session.
@elonmusk "There’s a need for connectivity in places that don’t have it and where it’s limited or expensive. You can think of Starlink as filling in the gaps between 5G and fibre to reach the most difficult 3-5%" #MWC21
@elonmusk - "The combined power of our satellites is over 5megawatts with 30 terabytes of data per second. In August we should have global connectivity for everywhere except the poles." #MWC21

There’s been a lot of confusion centered around this (very cool) video of yesterday’s Falcon 9 launch so I wanted to jump in and clear some things up

Short thread…
#AvGeek #Falcon9 #SpaceX @elonmusk
For starters, I recommend checking out this earlier thread I wrote on vapor cones and expansion fans as a lot of relevant points are covered there, so I won’t circle back to everything

This should explain the *transonic* vapor collar close to the rocket
Okay, so the audio in the original video is misleading. This event happened at about 9km altitude, so any wave generated at that instant would reach the ground roughly 30sec later. Not sure how the audio was synced but if it’s real time from the ground, it’s coincidental

🔴 “UNA AYUDITA”
El fundador de @Tesla y @SpaceX donará US$50 millones para el ganador, 20 y 10 millones respectivamente para el segundo y tercer lugar.
Mr. @elonmusk dará 25 becas para estudiantes valoradas en 250.000 destinadas a los estudiantes que participen en el concurso.
Con el premio total de 100 millones de dólares, @elonmusk busca soluciones que puedan "extraer dióxido de carbono (#CO2) directamente de la atmósfera o los océanos y encerrarlo permanentemente de una manera ambientalmente benigna".
Cuánto dinero recibió de la @NASA?
Qué tipo de combustible ⛽️ utilizan los cohetes 🚀 de #SpaceX ?
Imagino que no emiten #CO2?
Automóviles 🚗 eléctricos con @Tesla todo ok ✅
➖Hace negocios con #China? O con empresas y países que no están en el acuerdo de #Paris?
➖Preguntas, nada más🤷‍♂️

This way the customer is not building the satellite from scratch.

C) These satellites will work perfectly with the ASTRA launch vehicles for even more efficiency.

D) This cuts down the idea-to-launch-timeframes by an order of magnitude, & cuts costs down for everybody.

Their executive team appears to be stellar with a ton of experience in this space, including having worked at @SpaceX and @NASA.

It makes sense, considering they are the 3rd private company to ever achieve orbit, and they did it faster than anybody else, ever!

En unas pocas horas @blueorigin estará lanzando su cohete suborbital #NewShepard, nombrado en honor a Alan Shepard, primer yanqui en hacer un vuelo espacial suborbital en 1961.

Este cohete realizará un total de 12 experimentos, incluyendo la prueba de sensores para #Artemis.
@blueorigin es la empresa de exploración espacial del billonario @JeffBezos. Se la ha criticado múltiples veces porque, a pesar de múltiples millones invertidos, no han tenido aún ningún vuelo a órbita.

Esto cambiará el año que viene cuando vuele su nuevo cohete New Glenn
Este cohete es en honor a John Glenn, primer astronauta yanqui en volar en órbita, en 1962.

Su primera etapa será reutilizable, similar a como aterrizan los #Falcon9 de @SpaceX. blueorigin.com/new-glenn

Vanavond (do 17e) om 20:19 NL tijd lanceert @SpaceX mogelijk weer een serie van 60 #Starlink-satellieten.
23 minuten later, rond 20:42 NL tijd, is in de avondschemering de #Falcon9 raket *MAAR NOG NIET DE SATELLIETEN* vanuit NL te zien, met het blote oog.
Kaartjes: ImageImageImageImage

Waarom alleen de raket en nog niet de satellieten? Dat is omdat de satellieten dit keer pas één uur na de lancering van de bovenste trap van de #Falcon9 worden losgelaten. Als het spul 23 minuten na de lancering over ons komt, zijn ze dus nog niet los van de raket!
3/4
Morgen, vrijdag de 18e omstreeks de zelfde tijd (1 minuut verschil: rond 20:43 NL tijd) komen ze weer over en dan is waarschijnlijk het inmiddels klassieke 'treintje' te zien. Hoe helder ze dan zijn durf ik echter niet te zeggen, nu @SpaceX allerlei experimenten doet.

Yeni uydumuz @turksat 5A'nın adını önümüzdeki aylarda sıkça duyacağız. Bu bilgi selinde uydumuz ile ilgili temel bilgileri sizlerle paylaşmaya çalışacağım. uzay-uydu konularına aşina olmayanların da rahatlıkla anlayacağı şekilde aktarmaya çalışacağım.
5A uydusu Kasım 2017de imzalanan sözleşme ile Airbus Defence And Space @AirbusSpace firmasınca yapılmaya başlandı. Görece kısa bir süre içerisinde firmanın Fransa Toulouse şehrindeki Uydu Montaj, Entegrasyon ve Test Merkezinde üretimi tamamlandı. Testler devam ediyor.
Uydu 3,5 Ton ağırlığında. Görüntüdeki insan boyutu ile karşılaştırılabilir. Güneş panelleri açıldığı zaman çok daha büyük olacağını hatırlatmakta fayda var. E3000e platformu üzerine inşa edilen uydu 10 kW gücünde faydalı yükü taşıyacak. Uydunun 15 yıl hizmet vermesi planlanıyor.

@elonmusk ImageImageImage
In the wee hours of the morning in India, on the other side of the world, @SpaceX was busy getting its signature @Falcon9 rocket back in action.

#SpaceX
Not only did it place Argentina’s #SAOCOM1B satellite and two smaller piggyback satellites into Earth’s orbit, Elon Musk’s space company also completed its first polar orbit mission from Florida.

A rocket fan of China stayed at home for half a year coz of the epidemic.
In this period, he designed his own rocket equipped with vector engine, using solid fuel, and recyclable.
Finally, his rocket was launched successfully! (1/3)

SpaceX: En 1 de mis grupos dijeron:
Es solo otro lanzamiento de un cohete+!
Equivocado!
Es el primer cohete construido x una empresa privada, con patentes propias.
Y que hace de especial este cohete?
Entre otras cosas q se recicla.⬇️
#SpaceX #CrewDragon #Falcon9 #LaunchAmerica
El cohete, se divide en varias partes.
La primera, el propulsor que está llena de combustible y dá el 1er. impulso al despegar ya deja de ser una basura como en cohetes anteriores, se desprende y vuelve a aterrizar, se imaginan el ahorro de dinero?
Además menos basura⬇️ #SpaceX
Acá podemos ver desde la cámara del propulsor el aterrizaje en la base marina, es tan preciso que en vez de hacerlo en un desierto lo hacen en esta plataforma marina, en el centro mismo.
El propulsor ahora es reutilizable. logrando así bajar los costos de las misiones. #SpaceX

There will be a #Hayabusa2 post-touchdown press conference at 2:00 UTC today (tonight), streaming at - I reckon it'll be in Japanese only. (And 15 minutes after the #Falcon9 lift-off if that happens on time - space action around the clock ... :-)
Nothing noteworthy noted while @haya2e_jaxa was at "gate 5", so it's returning to its standard parking position in 20 km distance from #Ryugu now - the webcast is over, and it's unlikely we'll learn more before the press conference in 1 1/2 hours.
Looks like at we will get the #Hayabusa2 post-touchdown press conference at the top of the hour with an *English* translation. (While at the @SpaceX webcast should still be running - just not enough time for so much space ... ;-)

#Hilo Atentos los fans de la ciencia y el espacio porque hoy os contamos una historia astronómica: La de Gwynne Shotwell, la mujer detrás de las naves espaciales de #SpaceX
“¿Cómo funcionan los coches?” Esa fue la pregunta que Gwynne Shotwell le hizo a su madre cuando aún estaba en su colegio de Illinois. Su madre, una artista perdida en el tema, le regaló un libro sobre motores y engranajes. Gwynne lo devoró en pocos días. Y así empezó todo
Con tan solo 15 años decidió dedicarse a la ingeniería y desde entonces empezó a formarse en física, astro física y mecánica. Poco después se graduó en la Universidad de Northwestern en Ingeniería mecánica y Matemáticas aplicadas
