@__apf__ We’re in San Anselmo next to San Rafael and the way my kids Spanish teacher pronounced ‘raff-aye-ell’ is burned into my brain.

every city name in California has three ways to pronounce it: (1) the Spanish way (2) the way an English speaker would pronounce it if they hadn't heard the name before (3) the way locals actually pronounce it, which is neither of the previous two. like San Rafell and Beneesha

After mating the Pegasus rocket carrying Katalyst's LINK spacecraft, @NorthropGrumman’s Stargazer L-1011 aircraft departed Wallops. Wallops' ability to support both spacecraft & Pegasus integration within weeks streamlined this mission to boost Swift's orbit later this summer. go.nasa.gov/4aaYaq4

@robertoblake I agree… but Super Metroid was from Gunpei Yokoi - and it’s one of the few 16bit games I go back to.

Getting close to my instrument checkride, and a few people have wished me ‘good luck’. And the truth is, I wouldn’t take the test if I needed good luck to pass. But, bad luck, that can ruin the best laid plans, so I’m still happy for the wishes and blessings.

SPACEX's PROJECT STARFALL SpaceX is targeting 6.43 a.m. EDT on Tuesday, June 23 for a Falcon 9 launch of its Starfall Demo Capsule from Cape Canaveral SFS, FL Starfall is not a traditional conical capsule. It features a flat, circular, disc-like form factor designed for autonomous space manufacturing and rapid global cargo delivery. The circular capsule measures 3.1 meters (10.2 feet) in diameter and 0.75 meters (2.5 feet) in height and has a dry mass of approximately 2,100 kilograms (4,630 lbs). Starfall features a two-part split structure comprising a 1,400 kg aluminum top plate and a 700 kg carbon-fiber heat shield. PAYLOAD CAPACITY Its internal payload bay measures 2.5 × 1.5 × 0.5 meters, allowing Syarfall to transport up to 1,000 kilograms (2,205 lbs) of return cargo. GUIDANCE & PROPULSION Starfall lacks a dedicated chemical propulsion system for independent deorbit maneuvers, relying on its launch vehicle or an external kick-stage to enter a reentry trajectory. For orientation and attitude control, the craft utilizes a network of cold-gas thrusters supplied by nitrogen tanks housed within the heat shield. REENTRY & RECOVERY Starfall uses its carbon-fiber thermal protection system to manage atmospheric heating. Deceleration is handled by a sequence consisting of a pilot chute, a drogue parachute, and a single main parachute. The 700 kg heat shield is mechanically jettisoned shortly before splashdown, after which SpaceX recovery vessels retrieve all spacecraft components from the ocean.

@MartyJ777 @DJSnM It's not new - there's been a traffic cone on the head of the Duke of Wellington statue in Glasgow since at least the 1980s... Queen Elizabeth II in Aberdeen wears one from time to time also. It's just a thing we do - every statue needs a traffic cone imho.

@jotunfo Yes and more energy means higher temperatures and pressure

@DJSnM I thought the Isp was purely limited by the temperature inside the rocket engine 🤔

A recent Long March 12 launch used a new high energy Kerosene which increases specific impulse by about 2.5%. The Soviet Union developed something similar they named 'Syntin'. The fuel uses cyclopropane rings where the molecule is twisted tight, like a spring, this means extra energy contained in the same mass of fuel.

@DJSnM @dpoddolphinpro Serious question: Do you calculate a new eye-to-wheels height interpretation of the VASI with the camera mounted, to avoid testing its impact rating?

@TheBrianMcManus @SynBio1 CT means computational tomography, there are many scanning processes that can be used to get the data for the CT step

I knew as soon as midjourney announced that CT scanner I was going to be treated to every medical imaging expert on earth posting every possible technical limitation of CT scanning that might make it not work Never change biotech

I love getting out of Washington and spending time with the people getting the job done! It was great visiting @NASAAmes for the annual center picnic, meeting employees, interns, and students, and hearing firsthand about the work shaping the future of science & exploration. I also had the chance to see some of the incredible capabilities that make Ames unique…from the world’s largest vertical motion flight simulator, where every Space Shuttle astronaut trained and no doubt those that will land on the moon will train, to the newly restored Hangar One, a landmark that represents both NASA’s history and its future. Every visit reminds me that America’s leadership in space is powered by the people who show up every day to solve hard problems and push the boundaries of what’s possible.

Question for the men in the group: do you know how to fix a tire? If you got a flat tire, would you fix it yourself or call AAA? (I do not need my tired fixed. I’m doing research.)
