I live in California & if you suddenly have a need to go camping out of state, I know some local legal camping sites that you can visit for your camping trip, & will provide a place to stay before & after your camping visit. And will never speak to others about your camping trip.

Today, every one of us is vulnerable to gun violence. Every one of us could be killed for what we believe, what we say, how we act. It doesn’t have to be so. We can do better!Those of us personally impacted can raise our voices, and tell about the pain, the grief, the trauma.

Never doubt that gun violence lives on in the hearts, minds, and bodies of those left behind. Never doubt the trauma that gun violence leaves in a family. It wreaks havoc. It devastates lives, and in his case, it altered a history that could have been, that might have been.

On this day in 1968, before many of you might even have been born, my uncle, Robert F. Kennedy was gunned down while running for president. Gunned down on his victory night. He left a devastated pregnant wife and ten children and a shattered extended family.

The @BoeingSpace #Starliner completed Orbital Flight Test-2, touching down at White Sands Space Harbor. This flight demonstrated launch, docking to @Space_Station, reentry, and landing — data to help prove that the capsule can safely carry astronauts. go.nasa.gov/3sZnARL

Coming tomorrow: #AtlasV #Starliner launch highlights! Here is a sneak peek of what you can expect.

I had the incredible opportunity to ride with the @BlueAngels and observe their team practice. Like many high performance teams, the Blues keep a “growth mindset,” giving feedback frequently, not just on performances. The flight was thrilling, and the debrief just as interesting!

A5/OFT-2: A couple of really nice shots of the Starliner's approach to the ISS last night taken by ESA astronaut Samantha Cristoforetti:

See #Starliner successfully, autonomously rendezvous and dock with @Space_Station during #OFT2. Through the combined work of @NASA and Starliner teams, the spacecraft connected to the Boeing-built International Docking Adapter at 7:28 p.m. CT.

A5/OFT-2 (3/3): All in all, Stich, Nappi and space ops chief Kathy Lueders say they're pleased with the Starliner's performance to this point; while not a trouble-free rendezvous and docking, the system worked well overall; a major milestone for Boeing
Retweeted by Mark Ratterman
A5/OFT-2 (2/3): Boeing VP Mark Nappi says engineers don't yet know what caused 2 OMAC thrusters in the Starliner's service module to fail earlier; several explanations have been discussed, but engineers may never know because the SM burns up during re-entry
Retweeted by Mark Ratterman
A5/OFT-2 (1/3): Summarizing a post-docking briefing: NASA Commercial Crew Program Manager Steve Stich says low temps in the Starliner's 2 cooling loops required manual intervention, but the system was never close to violating margins for docking; loops are stable

Congratulations to the Airmen & Guardians of Space Launch Delta 45, our Launch Acquisition Deltas, @ulalaunch, & @Boeing on this evening's successful OFT-2 launch. OFT-2 is the 2nd uncrewed flight of the Starliner spacecraft that demonstrated human transportation capabilities.
Retweeted by Mark Ratterman
While #Boeing may be behind #SpaceX on crew vehicles, this successful launch marks a HUGE milestone in the future of ISS crew flights. Both #Starliner and #CrewDragon are different enough that if 1 spacecraft has a problem, the other can still send people. "Dissimilar Redundancy"

Congrats to the Boeing, @ulalaunch and @NASA teams to name a few on a great start to the #OFT2 mission. Next stop for #Starliner...the #ISS! twitter.com/BoeingSpace/st…

LIFTOFF! @ulalaunch's Atlas V rocket launched from Space Launch Complex-41 at 6:54pm ET carrying @BoeingSpace's #Starliner spacecraft for Orbital Flight Test-2. OFT-2 will provide valuable data that will help @NASA certify Starliner to carry astronauts to & from @Space_Station.

I don't recall being able to hear AtlasV in flight through Atlas main stage booster cutoff, sure did this time! Go OFT2!
We are GO for launch. Liftoff of the @ulalaunch Atlas V rocket with @BoeingSpace's #Starliner atop is slated for 6:54pm ET: youtu.be/gy6iam6NjsU

Did you know? Today is the 675th launch of an Atlas rocket and the 375th to originate from Cape Canaveral. It also marks the 93rd #AtlasV mission and second in the N22 configuration.

We are now exactly three hours away from liftoff. Blue Team operations continue smoothly at the pad following hatch opening while launch team members here at the Atlas Spaceflight Operations Center monitor the health and status of #AtlasV systems. bit.ly/av_oft-2

No this is not @talkingspace stage for today's #OFT2 Launch. It's the NASATV broadcast setup, pretty nice!
Just finished recording a new @talkingspace ep with the brilliant and lovely @katrobison! Yes, it's ladies' week, from hosts to stories of women imaging black holes, launching to space, and even starring in a new graphic novel from @NASA. Coming soon to an app near you!

A5/OFT-2: The Atlas 5 and the Starliner crew capsule completed the 1,800-foot trip to launch pad 41 at the Cape Canaveral Space Force Station at 11:12am EDT, setting the stage for launch Thursday on a high-stakes test flight to the International Space Station; ULA photo:

NASA’s Steve Stich says no issues being worked by NASA, Boeing or ULA for the OFT-2 launch on Thursday. Vehicle rolling to the pad tomorrow.

Weather is still 70% go for a Thursday launch, with a chance of isolated showers. If launch delayed to Friday, slips to 40% go.

West: we're also concerned that SpX is moving on to Starship and won't build more Crew Dragons. Need to assess that. And worried about possibility of launching Starship at KSC from pad just 300 yards from LC-39A. Risk to cmrcl crew.
Retweeted by Mark Ratterman
David West: NASA assured us no rush between OFT2 and CFT. Tremendous amt of work to do. Won't launch till ready. BUT, we're concerned about low staffing levels at Boeing. Don't want delays due to lack of resources. And worried abt Atlas V phase out. Vulcan must be human-rated.

Continue to look for the Section 106 review and the Endangered Species Act Consultation to be checked off before you get your hopes up about the FAA publishing the result of the review. Those should happen first. permits.performance.gov/permitting-pro…

The Little Joe rockets were a series of two launch vehicles used for launch abort tests of the Mercury and Apollo spacecraft. These rockets allowed NASA to test the LAS during in flight conditions, verifying it could pull a crew away from a failing rocket.

A few Flies 🪰 were seen swarming around the Crew-4 dragon Freedom prior to launch. And what a beautiful launch it was! It’s amazing to consider the huge team of people who make sure both crew and vehicle are ready to fly. Human space flight is the biggest “team sport” there is!m

This time of year walking past a window with this view is like having a light switched on. The contrast of the green grass/weeds with the golden yellow flowers makes every day better.
