Not all Moon missions that crash are a failure!
The NASA Ranger missions were, literally and figuratively, a smashing success!

It's craters all the way down!
Some Moon missions that ended up in a crash were a success! This week on #MoonMonday we talk about the @NASA@twitter.com Ranger missions that intentionally hit the Moon. Paving the way for #Apollo.

Today’s #scicomm talk by @tifrarnab@twitter.com on periodic tables and where the elements come from reminded me that I need to change this now old chart.
Because, detection of colliding neutron stars happened!💥 https://t.co/op4sL1Jh5Y

And China will be sending a first sample return mission to the Moon’s surface after 40+ years. But this is nice too.

RT @JimBridenstine@twitter.com

We’re sending a CubeSat to the same lunar orbit targeted for Gateway as early as next December! @AdvancedSpace@twitter.com and @TyvakNanoSat@twitter.com will rapidly develop and build the vanguard mission. I’m excited to have two more U.S. small businesses be part of #Artemis: https://go.nasa.gov/2NZ6j7K

Landing a spacecraft on the Moon is hard. But if India is to play a leading role in sustained space exploration, we need to go back to the launch pad.

Check out my featured piece in @Openthemag@twitter.com which dives into the tech stack that makes #Chandrayaan2.

Guys, this week's @Openthemag@twitter.com has an expert column from me on the what #Chandrayaan2's failed landing (partially or otherwise) means for India's future in space. Go get a copy from the stands!

Can’t wait to see those mesmerizing clouds. 😍

RT @NASAJuno@twitter.com

@nasa_eyes@twitter.com I’m nearing my closest approach to the cloud tops of Jupiter. Speed: about 126,000 mph (202,000 kilometers per hour). If all goes well, pictures from this flyby should be available in the next few days.

official word is that @LRO_NASA@twitter.com will take an image of the Vikram landing site on September 17th. The incidence angle is pretty high, so it may be hard to see (could be in shadow).

The problem with the misinformation surrounding #VikramLander is @isro@twitter.com's mute state too. They remain silent themselves, but talk to media just the same.
1. If they didn't talk to media, they should come out and say so.
2. If they did talk to media, update official channels too.

If the #Chandrayaan2 orbiter made a major chunk of the "95% success" of the mission, it would've had a name.

Unlike Vikram and Pragyan.

RT @1amnerd@twitter.com

Some people have been saying Chandrayaan 2 was a 95% success after Vikram's autonomous descent failed. Where does this number come from, and what does it mean? https://thewire.in/the-sciences/if-chandrayaan-2-was-a-90-95-success-is-the-answer-whats-the-question via @TheWireScience@twitter.com

On defining metrics for completion of space missions.

Most people:
Successful > Mostly successful > Partial successful > Good try.

Me:
Successful > Kinda failed > Mostly failed > Failed.

People like us maybe a minority but we don't change or produce facts out of thin air!

Absolutely humbled to have the first guest post by a lunar scientist on my pet project @moonmondays@twitter.com. Thank you @IntrplnetSarah@twitter.com, the smallest of craters are indeed adorable! :)

Good to see @ISRO@twitter.com addressing the fake account problem. Need to take on the other rumors too, to contain the spread of misinformation malware.

RT @isro@twitter.com

It is noticed that accounts in the name of Kailasavadivoo Sivan is operational on many Social media. This is to clarify that Dr. K Sivan, Chairman, ISRO does not have any personal accounts.

Yet another fake account. Yikes.
