@Dr_ThomasZ @loriglaze @NASASolarSystem Congratulations!

#Congrats to @loriglaze, the now permanent director of Planetary Science. She leads NASA’s largest science division by $s. I am personally very excited to call her my colleague and look forward to seeing her impact grow even more - she has been great already! @NASASolarSystem

@torybruno @GeoffdBarrett This is why Brother Luck named his restaurant in the Springs “Four”—you can get all four seasons in one day in CO

@GeoffdBarrett Yes, we’re fine. Rough storm. Zero visibilty blizzard, 70 mph winds. 4 to 6 foot drifts at my house. Beautiful and sunny today.

Feels like a good day to go to space. #WGS10

Oh and my *two* sons are both home today! It may be pi day, but two seems to be number

Today is a good day. It feels like spring outside, I’ve finished two draft deliverables, and I had the opportunity to recommend *two* brilliant colleagues for positions #seniorprofessionalgoals #payitforward

@ltelkins @NASAPsyche But MOS/GDS PDR comes later, right?

And @NASAPsyche PDR Day 4: Damp rates following tip-off. That is all. Well, actually, there is also today: Harness, Imager, Gamma-Ray and Neutron Spectrometer, Magnetometer, DSOC accommodation, Mission Design, Ground Data, Science Data Center. 🚀🛰️

@elakdawalla @dwcssl can you help? Is Dave Brain active on this website?

Is there any solar scientist / plasma person out there who can explain what mass loading is to me in terms I can understand? ...where's Fran Bagenal when I need her?

@JimBridenstine A line item for #MarsSampleReturn is truly welcome news

@Dr_ThomasZ I’m looking forward to the same announcement regarding #Mars samples that have been carefully curated for decades

We’ve selected 9 teams to study pieces of the Moon that were gathered & sealed on the surface during the Apollo era. Stored untouched for ~50 years, I’m excited the samples will be opened for the 1st time to be studied by a new generation of scientists go.nasa.gov/2TAmbAT 1/2

@ltelkins @greg_asner @planetlabs @ASU @ErolFoundation In the 90s, I delivered and flight tested a prototype of an airborne UHF radar to measure the biomass of triple canopy rainforests. Tests were successful (within +/- 5% of ground truth). #BioSAR #ZAIAmelex #CarbonSequestration

BIG breakthrough -- near real-time monitoring of forest carbon stocks and emissions. Great work by @greg_asner, @planetlabs, @ASU, @ErolFoundation. planet.com/pulse/developi…

@dougbrec @SciGuySpace Human rated/crewed

What is the lead time for ordering a new Delta IV Heavy rocket? A new Falcon Heavy?

Opportunity's Last Look @NASA declared the @MarsRovers mission complete in February, but the final image has just been processed. Check out annotated and interactive full-resolution versions of the panorama at go.nasa.gov/2F7JWbn

@jeff_foust Wait. What?

Bridenstine: we’re the only country that has landed a robot on another world. 🤔

@_Astro_Nerd_ How about engineers? 🖐🏼

Re Europa Clipper on a commercial rocket, not SLS, that's not news. NASA said the same thing in its budget request last year. Congress nevertheless directed that it be launched on SLS. And last year NASA said launch in 2025. This year it's 2023, also as required by law.

The budget request covers JWST, but zeroes out @NASAWFIRST and #STEM engagement, among other puts and takes.

Let's keep finding ways to make "failure" a synonym for "failure is just data" and "still working on it, because I am determined and this thing is worth it!"

In honor of #InternationalWomensDay : the women of the @MAVEN2Mars team. Overall still the best team I’ve worked with and—probably not coincidentally—the one w the most women

Feed your brain with space facts this #NationalCerealDay. 🥣 "Cereal" is derived from Ceres, the Roman goddess of agriculture and grain. Ceres is also the name of the dwarf planet explored by @NASA_Dawn. go.nasa.gov/2C8Q2Gl

#MAVEN today performed an aerobraking maneuver (0.2 m/s ∆V) to decrease the periapsis (lowest) altitude by 1.2 km. MAVEN’s periapsis altitude is now 125.5 km and the apoapsis (highest) altitude is 5,400 km. The density of #Mars' atmosphere at periapsis is 3.4 kg/km³.

For the final plenary of #IEEEAerospace2019 @cyberlyra is sharing her research about how/why the #MarsRovers team was...err, is so special
