What has changed between first few acceptable Starship ocean landings and now two of them disintegrating? SpaceX has to quickly modify design and redeploy STARSHIP successfully to not close all options of reaching Moon again at least? First step is LEO orbits STARSHIP survival and repeatability...

Reverse might be true? How do we know as to how many of Oort cloud objects have been former comets or asteroids captured in those clouds! Dohnanyi meteorite type curves for size distributions may have to be developed based on gravitational perturbations on multipole distributed gravitational...

The recent pushback by 3 days to March 3 still does not aim at SHIP completing earth Orbits? SpaceX teams - please achieve full earth orbits with STARSHIP to further qualify it for trip to Cislunar space and eventually may be a less heavy version for Crewed qualification, timeline is not like...

When I worked on the Apollo Program, we accomplished more on each Saturn V development. The SpaceX model is rapid fire and thus measure of incremental success is smaller and we do not yet have an orbital reliability of the STARSHIP. It is necessary for SpaceX to narrow the gap in becoming the...

Even after 50+ years of Apollo of which I am a proud beneficiary I am sorry to see the waste of taxpayer resources by a select group of old stalwart companies that made Apollo Possible. Retiring Shuttle was premature making us dependent for nearly a decade Auditing wasted money on big contracts...

Yes agree and also to add that over long periods the very stars and other components of interstellar medium with central singularity (black hole) change distribution of mass and thus dust stars ions etc., in the galaxy.

I am not favoring any ideology or any party. I benefitted from a President's announcement that we had to reach Moon by end of decade and the whole country and many of us from elsewhere contributed as well as received Apollo Awards. Details were not provided by President, it was a need and a...

Observations inspired by previous 80+ comments: Humanity's quest for knowledge and spirit for adventure to know the unknown is insatiable. Space as a vast unknown void inspires explorers. They will find ingenious government, foreign, industry and international means to get resources! Synergy...

What is the conclusion on slow progress in qualifying STARSHIP to be at least flight worthy translunar capable rocket like we had done for Saturn in just few flights. Still the descent ascent and legs are to be separately qualified? Solutions such as jettisoning a heat shield after descent...

Historic Milestone 3.8M miles from Surface of Sun – NASA Solar Parker Probe Launched in 2018, Dr. Ravi Sharma, NASA Apollo Achievement Award 1969 Some of my NASA and Space industry colleagues are capable of outlining several technologies that would accelerate from translunar or escape...

Great effort, have not assimilated all yet. But initial Qs Why only neutrios, why not other fundamental Standard Model Particles why not some resonances and "particles" discovered Beyond SM? why can DM not coexist with all SM particles and resonances as soup. I found some youTube references...

As long as P and Q are separate projects and accounting is kept in accordance with US OMB or congressional oversight then there should not be negative influence of say self funded Mars mission vs Federally funded Moon or Artemis mission. One can use capabilities to reduce costs. Let us not...

Some of these suggestions probably can help SpaceX team as they donot have and think that they do not need experience of previous moon missions. Product improvement is desired esecially with taxpayer money based projects. Even if Starship is ready is Artemis Next human mission close? Also we...
