NASA is just over 10 minutes away from smashing a spacecraft into the asteroid Dimorphos, in a planetary defense demonstration.

Watch the #DARTMission impact live:
The #DARTMission
launched on a SpaceX Falcon 9 rocket last November – here's some background on the mission: cnbc.com/2021/11/23/spa…
From the live DART camera, the larger asteroid Didymos alongside its smaller compatriot (and tonight's target) Dimorphos: Image
NASA TV hosts note that there is a 30-second lag in the data, plus a few more seconds for image processing of what we're seeing on the webcast.

5 minutes to impact.
DART is closing in - less than 2 minutes to impact
NASA is removing the impact countdown clock from the livestream, going by loss of signal to confirm collision.
Dimorphos in full view now #DARTMission
Loss of signal confirmed!

"We have impact"

NASA's #DARTMission hits the asteroid Dimorphos
Lots of happy folks at @JHUAPL, with @Dr_ThomasZ among them
@JHUAPL @Dr_ThomasZ Here's a sped-up replay of the #DARTMission approaching and colliding with Dimorphos
@JHUAPL @Dr_ThomasZ NASA chief @SenBillNelson: "I believe it's going to teach us how one day to protect our own planet from an incoming asteroid ... We are showing that planetary defense is a global endeavor, and it is very possible to save our planet."

Elon Musk is holding a Twitter Spaces discussion on SpaceX's first Starship launch.

Thread: Image
Musk: "The outcome was roughly in what I expected, and maybe slightly exceeding my expectations, but roughly what I expected, which is that we would get clear of the pad."
Musk: "I'm glad to report that the pad damage is actually quite small" and should "be repaired quickly."

After the dramatic first Starship Super Heavy launch, a look at SpaceX's monster rocket program – with the good (prototypes in the wings), the bad (destruction and debris at and around the launchpad) and the unknown (regulator investigations underway):
cnbc.com/2023/04/29/spa…
NASA chief @SenBillNelson: “I have asked, so I can report to you ... SpaceX is still saying that they think it will take at least two months to rebuild the launchpad and concurrently about two months to have their second vehicle ready to launch."
cnbc.com/2023/04/29/spa…
@SenBillNelson Nelson effectively defended SpaceX before a Congressional committee on Thursday, explaining how the company is "hardware rich:"

"They launch, if something goes wrong they figure out what it is, they go back and they launch it again."

SpaceX is preparing to launch for the 29th time this year, and the second time this evening, with a Falcon Heavy rocket carrying satellites for Viasat and Astranis.

This rocket is expendable, so its boosters will not be recovered.

The annual #SATShow rocket roundtable, moderated today by @Sandra_I_Erwin, with:

ULA CEO Tory Bruno
SpaceX VP of Commercial Sales Tom Ochinero
Arianespace CEO Stephane Israel
Rocket Lab $RKLB Senior Director Richard French
Blue Origin VP of Commercial Sales Ariane Cornell
@Sandra_I_Erwin @SATELLITEDC @ulalaunch @torybruno @RocketLab @blueorigin @arianecornell @arianespaceceo @Arianespace @SpaceX French: $RKLB spacecraft components and integrated satellite systems business combines with launch, "working to bring the lowest total cost ... back to customers."

"Really exciting to see our diversifying revenue and being able to stabilize the lumpiness of launch."
@Sandra_I_Erwin @SATELLITEDC @ulalaunch @torybruno @RocketLab @blueorigin @arianecornell @arianespaceceo @Arianespace @SpaceX *Bruno asks the crowd if they like the red paint job on Vulcan*

"Only one yes? That's it, sorry."
