I don't know what's causing me more cognitive dissonance... the term "massive planetesimal collision" or trying desperately hard not to turn the first letter of a certain researcher's name into a "C" when discussing a "ghost planet"...

Not saying it couldn't have been possiblity, i think due to the distance were observing these exoplanets, that its just moved into position we simply can't see it.

Aren't we looking at it from above the ecliptic? There shouldn't be anywhere to hide...

Well, there stuff between us and that exoplanet. Something could have move in the way like interstellar debris for that moment, catching the light of the planet. (shrugs)

That someone ticked off the Empire, they used the Death Star on the thing.

Okay, this is strange.

NASA head of Manned Spaceflight steps down

Quote
"Throughout my long government career of over four and a half decades I have always found it to be true that we are sometimes, as leaders, called on to take risks," Loverro wrote. "The risks we take, whether technical, political, or personal, all have potential consequences if we judge them incorrectly. I took such a risk earlier in the year because I judged it necessary to fulfill our mission. Now, over the balance of time, it is clear that I made a mistake in that choice for which I alone must bear the consequences. "

And just a week before the first manned launch off US soil in years. Most peculiar.

I'd have thought it another "inappropriate relationship with underling", except why would he think that "necessary to fulfil our mission"?

Strange days indeed.

Strange days indeed.

Has nothing to do with the Crewed Dragon launch.  Timing is coincidental and it won’t affect.  Lots of NASA folks can lead a launch readiness review.

As reported by WaPo and NPR and indicated by his resignation letter, Loverro did something against regulations to accelerate the recent procurement of studies and risk reduction activities for three human lunar lander proposals.  Whatever Loverro did gave NASA’s Associate Administrator (the highest civil servant in the agency) no choice but to ask for Loverro’s resignation.

Bigger immediate question is whether that procurement gets derailed and those lunar lander studies go back to square one.  That would be a shame as it’s taken NASA 16 years just to get to this point since the Vision for Space Exploration directed NASA to return astronauts to the Moon.

Longer-term is who replaces Loverro, and whether they maintain the reorganization, reforms, and leadership team Loverro had put in place over the past half-year to oversee NASA’s human space flight activities.  If Bridenstine remains NASA’s Administrator, then someone like Loverro will replace Loverro.  If there is change at the top of NASA (like after the election), it’s harder to say.

Well, i think there space launch today if i'm not mistaken. I know SpaceX's other project, Starship still having issues. They're having string of bad luck getting the new Raptor engine to startup correctly for static fire test. Yesterday's test ending up with engine ignition test unintentionally caught the rocket on fire.  So god knows how long it will be till they get their acts together.

Hopefully Crew Dragon's flight goes uneventful next week.

When worlds collide?

https://www.youtube.com/watch?v=nWvP7FNPdyM

Fomalhaut b increased in brightness as it approached the inner edge of the dusty icy debris ring, and then faded from view as it plunged into the ring.  The above video makes it look like a case of "doubly reflected light", i.e. the planet was increasingly illuminated (on its side nearest us) by the "ring shine" of starlight reflected from the icy ring particles on initial approach... until it plunged into the ring and the very same dust & ice obscured the planet. 

Cassini was plausibly similarly illuminated by Saturn's ring shine as it approached the planet

Pluto may have once had a ocean.   CNN reports that New Horizon probe data shows there strong sign there was once a heated subsurface ocean which was suspected to been  heated by the rocky core's radiation.  Cracks on the surface are consistent with theory this maybe the case.

If it had liquid water from internal heating alone, that's going to massively shift the habitable-zone estimates.

IF.

I'm fairly sure the hab zone is defined as liquid SURFACE water. Otherwise the Jovian moon system would be included already (Europa's likely water ocean).

Pretty much every moon beyond the frost line of sufficient size and with a core is usually suspected to have or have had an internal ocean at the core-mantle boundary.

Among the 20 "rounded" moons in the solar system half (!) are suspected to have a current liquid internal ocean, 20% are suspected to have had one that froze after the core turned cold (this includes Charon), and only 30% never had one.

The last category of moons without past or curent oceans includes the two silicate moons Luna and Io, the probably-collision-accreted dustball Proteus and the homogenous iceballs without much of a core that are Mimas, Iapetus and Thetys (and yes, there's an irony in that).

I think Habitable zone is when surface of the planet is liveable Earth style life forms.  However, unique life properly can find way to survive if given the time and right elements are in place.  Pluto may not have had right mix to keep consist opening for life to develop (we plain don't know, we haven't checked out other potential worlds/moons that are local which have frozen oceans.

Virgin Galactic continues to test, maybe will see flight this year's end with passengers (employees likely).



They just did their 2nd unpowered glide test this year.

Volcanoes on Venus seem to be still alive! The University of Maryland released a study that shows Venus is still having active eruptions.    Does that mean its core not spinning enough for volcanic activities but not enough for magnetic field?

Core spin doesn't have much to do with volcanic activity; thermal energy inside leaking out does. Venus spins too slowly to support much of a magnetic field, true.

I was hoping that with something like 2 decades of observations, we'd have seen something new new, not "last 2-3 million years" new, but hope spring eternal ...

Given the low number of vulcanoes on Venus there's about a one-in-five chance that there's just a single one active anywhere on the planet. Active meaning having erupted in the last 10,000 years...

One of the three left-over candidates for ESA's M5 mission for a 2032 launch is EnVision, a rather large 2.6-ton Venus orbiter that would specifically look for geological activity with multiple radars. One main design driver is the required 800 MBps connection back to Earth - consider that relative to current Mars orbiters having around 5 MBps downlink.

EnVision is competing for funding against two space telescope missions, decision to be taken Summer 2021.

It's tough to push against space telescope missions.  Bureaucrats are thought to like the science now aspects of them, compared to the more science later aspect of planetary missions.

But EnVision has one thing going for it: Venus is not that far away. 

Hopefully it gets the nod.  I love planetary science.

NASA has launched the new Perseverance  probe on its way to Mars to search for signs of life.  It is currently in safe mode but will be "waking up" well before it gets to the Red Planet.   Read about the launch above.
