#SpaceX is targeting an atmospheric test flight of their 10th #Starship prototype today from Boca Chica, TX. The countdown was just held due to a stuck valve and the actual launch time is still to be determined.
No webcast link available yet. One is expected before launch.
UPDATE: #Starship#SN10 is targeting a launch within the next 10 minutes. The Verge reported a launch time of 6:13 EST, and tanking procedures are lining up accordingly.

Hogg: "One of the great things is that things happen for the very first time every day. For example, the first image, the first report, the first color panorama, the first instrument checks, and the first time we get to see major system parts working."
NASA is set to hold a briefing in just 5 minutes on Perseverance's post-landing operations and to unveil the entry, descent, and landing imagery captured for the first time ever.
Participants:
Thomas Zurbuchen, assoc. admin, SMD, HQ

Good morning. We're currently at T- 50:00 to the 15th launch of Northrop Grumman's Cygnus resupply vehicle, destined for a two-day ISS rendezvous. #NG15
Ready for the #CountdownToMars? #Perseverance is set to begin its entry, descent, and Martian landing in just under 5 hours from now, at 12:55 p.m. PST (20:55 UTC). We'll be covering it here on Twitter.
In order for today's landing to work successfully, the #Mars2020 mission needs to bleed off over 5,000 m/s of velocity within just four minutes, and conduct a rocket-powered crane descent. Here's today's descent timeline - also included in the article. #CountdownToMars
At 11:15 a.m. Pacific, NASA will start coverage of the landing on NASA TV, available globally. We'll be tweeting clips during our coverage, too.
UPCOMING: NASA is holding another conference in 25 minutes (5:30 p.m. ET, Jan 19) to discuss the SLS Green Run hotfire test.
We will be covering it under this thread, or you can listen in on NASA TV:
Attendants: @JimBridenstine - NASA Administrator @KathyLueders - Assoc. admin for HEOMD
John Honeycutt - SLS Program mgr, MSFC
Julie Bassler - SLS stages mgr, MSFC
Ryan McKibben - GR test conductor, SSC
John Shannon - @BoeingSpace SLS mgr
Jeff Zotti - @AerojetRdyne RS-25 director
The update will also be here, though, NASA hasn't started it yet.
