I am seeing some ill-informed takes on today's near-miss in orbit so would like to offer some trajectory corrections if I may. Firstly, the chance that a single collision would trigger a catastrophic 'chain reaction' that would sweep through LEO is tiny.
For every close pass involving catalogued objects in orbit we can estimate a collision probability, or Pc. The Pc is between 0 and 1. If it is 1 we can say that a collision is certain. If it is 0 then we can say that a miss is certain.
The event today may have had a Pc between 0.02 & 0.2. In any case, the Pc was relatively small (compared to a Pc of 1) so a miss was the most likely outcome. For a chain reaction to occur a long & sustained sequence of collisions would need to take place.

💥WHY I HAVE OVER $1 MILLION IN $TSLA STOCK💥

Tesla's price may seem out of whack today. The P/E Ratio is insane, right?

But Amazon had similar P/E ratios back in 2014 and 3X higher in 2012. Look at where $AMZN is today.

(1/25)
$TSLA is my #1 stock because I am looking 5+ years out from today and basing my investment on that. Many people aren't doing that. Many people are looking at current or trailing earnings and comparing them to other vehicle makers.

(2/25)
And yes, I do fully expect there to be some major price pullback -- maybe even a short 30 to 50% drop in $TSLA price at some point, but over the long run, I think it goes way up.

🔴 “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🤷‍♂️

🔥I JUST bought $300,000.00 in ASTRA ( $HOL ) STOCK!🔥

1/ It's a #SpaceX type company & I'm very excited!

Read the 61 thread post below with my notes on WHY I did it. 👇👇👇

>>AND RETWEET THIS, PLEASE.<<
2/ #ASTRA ($ASTR) currently trading under the #SPAC symbol $HOL (Holicity)

It is a space company the manufactures smaller rockets and #spacecraft to allow businesses to launch into space very quickly and cheaply, from anywhere in the world.
3/ I first bought 10K shares of $HOL last week at $15...

... an additional 7500 shares this morning in pre-trading @$20/share...

...for a total of $300,000 (actually $304,233 / I rounded the share prices.)

In the last #SOCRATES report of 2020 #Starlink satellites accounted for 29.1% (1-in-3.4) of all 44,530 close approaches < 5 km recorded for the first week of January 2021 with a total Pc of 1.7% #SpaceDebris
Ignoring Starlink-on-Starlink conjunctions the constellation satellites accounted for 9.8% of all close approaches < 5 km.
The yearly rates based on this report are 675,451 close approaches < 5 km involving #Starlink (227,655 ignoring Starlink-on-Starlink conjunctions)

#bhartiairtel ने ३० जुलै २०२० रोजी #One_web या UK-based company ची‌ ऐतिहासिक ४५%‌‌ भागीदारी जिंकली..यामुळे येणार्या काळात जगभरामध्ये डिजीटल उत्क्रांती येणार अशी‌ चर्चा आहे.One web ही Satellite मार्फत दुर्गम व अतिदुर्गम भागात इंटरनेट पुरवण्याचे काम करते.२०१०-२०११ मध्ये स्थापना
झालेली ही कंपनी असुन यांचे लक्ष आहे जगात प्रत्येक ठिकाणी (डोंगर,जंगले,बेट सुद्धा!!) कमी किंमतीत उच्चप्रतीचे इंटरनेट पुरवणे.
त्यासाठी ही कंपनी जवळपास २५०० satellite सोडणार असुन त्यामुळे Mega-constellation पद्धतीचा वापर होणार आहे..प्रथम आपण Mega-constellation बद्दल जाणुन घेऊ..

It's time for my (seemingly monthly) look at conjunctions involving #Starlink satellites, as predicted by celestrak.com/SOCRATES/. In this month's update I have corrected an error in the conjunction rates for June, July & August (I missed some conjunctions) (1/n) #SpaceSafety
In the SOCRATES report from 30 September 2020, with just over 680 #Starlink satellites in orbit (v0.9 & v1.0), there were 6957 conjunctions < 5 km involving at least one #Starlink satellite (17.7% of all conjunctions in the SOCRATES report) for the 7 days ahead) (2/n)
The number of conjunctions < 5 km involving a #Starlink satellite & something else (i.e. not Starlink) over the 7-day period was 2828 (7.2% of all conjunctions in the SOCRATES report) (3/n)

En menos de 1 hora tendremos un despegue más de @SpaceX para desplegar su red de satélites #Starlink para dar cobertura de Internet a escala global.

Es realmente impresionante la ingeniería de este cohete. Unos minutos tras su despegue intentarán aterrizar su primera etapa 🚀🙀
Hora del despegue:

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
2/4
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.

Observations & model of daily count of close approaches in orbit involving #Starlink satellites from 1 October 2019 to 31 August 2020. Close approaches shown exclude Starlink-on-Starlink events for miss distances of < 5 km and < 1 km. Data from SOCRATES #spacedebris Graph showing daily close a...
Over the period: Starlink satellites were deployed at a rate of 1.81 per day. Each Starlink satellite deployed in orbit adds 0.48 conjunctions per day < 5 km.
14.6% of all close approaches - about 1-in-7 - of the 37,910 events in the 31 August 2020 SOCRATES report involved Starlink. This proportion includes Starlink-on-Starlink close approaches.

New response to @FCC by @SpaceX identifies probability of #Starlink collision with large #spacedebris is 8E-5. Single conjunction event < 0.5 km on 2 July with SL-3 R/B predicted by SOCRATES on 30 June 2020 had max. probability of 3.5E-5 (dilution thresh: 0.169) Image
Another event in the same SOCRATES report predicted miss of 172 m on 30 June with 3CAT-2 & max. probability of 1.39E-4 (dilution threshold: 0.044).
I realise that I am quite likely comparing apples & oranges here, but that's also one of the points I am trying to make.

Thanks @beckyferreira for this nice piece quoting me and not just my infamous tweet. To temper things down (because they got out of control, seriously): I don't hate @elonmusk and everything he/his companies are doing. @SpaceX and its engineers are amazing in many ways.... 1/n
..and the I also have a tremendous respect for the employees of @SpaceXStarlink working on those technical challenges, trying their best to mitigate the impact of their fleet. Musk and @SpaceX have been open to discussions and inputs from the astronomy communities. 2/n
I also feel like we are just “whining privileged” people with a telescope in a backyard, a camera on a tripod.
But at the same time, I am *personally* not convinced sending a bazillion satellites is the best option to remedy for the inhomogeneity of internet service access. 3/n

In 2019 I presented a paper at the 1st International Orbital Debris Conference looking at implications of relocating satellites of a large constellation from high LEO altitudes to low LEO altitudes (hou.usra.edu/meetings/orbit…). Here's a thread on some new analysis #spacedebris 1/n
In my presentation I pointed out that relocating satellites to lower altitudes might solve long-term space debris issues but wouldn't be risk-free & could introduce problems related to space safety. Adding traffic to an already busy region could increase conjunction events (2/n)
Space systems at altitudes below 600 km are typically small satellites such as cubesats. Often these do not have a propulsion capability and so cannot implement collision avoidance manoeuvres. The figure shows recent launch activity & spatial density (data courtesy of @ESA) (3/n)
