57 total launches from Florida last year from all providers is certainly prolific, without SpaceX's Starlink effort though that launch cadence would still roughly mirror that of 3-5 years ago. This year so far, four of SpaceX's eight missions have been Starlink.

This stat released today by @BryceSpaceTech is rather interesting: About 50 percent of SpaceX launches supported deployment of the company’s Starlink constellation, reaching 3,300 operational satellites in orbit at the end of 2022.

Heartbreaking and fascinating article from @a_leinfelder on the legacy of the Space Shuttle Columbia disaster on its 20th anniversary. houstonchronicle.com/news/houston-t

20 years ago, the Columbia crew lost their lives in the pursuit of exploration and discovery. Today, we lift up their legacies, and embrace NASA’s commitment to safety and the lessons we’ve learned. May we carry their spirit with us as we venture out to the Moon, Mars and beyond.

On Tuesday, Jan. 31, Demo-2 astronauts Douglas Hurley and Robert Behnken will receive the Congressional Space Medal of Honor for bravery from @VP Kamala Harris. Live coverage is scheduled to begin at 4:15pm ET (2115 UTC) on social media and NASA TV: go.nasa.gov/40giU9m
Astronauts Douglas Hurley and Robert Behnken wave during rehearsals for their Demo-2 flight to the International Space Station. Bob and Doug are walking down an asphalt-covered path outside Kennedy Space Center's Neil A. Armstrong Operations and Checkout Building; both astronauts are in their full launch gear, a white spacesuit with black boots, a futuristic-looking helmet, and the "NASA" worm insignia in small red text on their chests.

Starship is unstacked. Now SpaceX will prepare for a static fire of all 33 rocket engines. A static fire is a test where the rocket is secured to the pad and the engines are lit for a short period of time.

Woah. This will be very loud. Firing 33 engines at once! It’s a first for SpaceX. And an orbital launch could be getting closer for South Texas.

I missed this yesterday! The Webb telescope has confirmed its first exoplanet.
Quote Tweet
A whole new world! 41 light-years away is the small, rocky planet LHS 475 b. At 99% of Earth’s diameter, it’s almost exactly the same size as our home world. This marks the first time researchers have used Webb to confirm an exoplanet. go.nasa.gov/3VY5WK1 #AAS241

Graphic titled “Rocky Exoplanet LHS 475 b Transit Light Curve, NIRSpec Bright Object Time-Series Spectroscopy.” Behind the graph is an illustration of the planet and its star. The graph, or spectrum, shows the change in relative brightness of the star-planet system between 3:00 p.m. and 6:00 p.m. in Baltimore, Maryland, on August 31, 2022. The spectrum shows that the brightness of the system remains steady until the planet begins to transit the star. It then decreases, representing when the planet is directly in front of the star. The brightness increases again when the planet is no longer blocking the star, at which point it levels out. The graph shows data in purple circles, which chart measurements before, during, and after the transit. Data form a U-shaped valley of low brightness labeled “Starlight blocked by the planet” at 5 p.m. This dip cuts into a flat plain of high brightness labeled “Starlight,” which starts before the U-shaped dip, and resumes after the dip.
