On the evening of July 12th, SpaceX technicians put Starhopper’s freshly-installed Raptor – serial number 06 (SN06) – through a simple but decidedly entertaining test, effectively wiggling the engine in circles.

Designed to verify that Raptor’s thrust vectoring capabilities are in order and ensure that Starhopper and the engine are properly communicating, the wiggle test is a small but critical part of pre-flight acceptance and a good indicator that the low-fidelity Starship prototype is nearing its first hover test(s). Roughly 48 hours after a successful series of wiggles, Starhopper and Raptor proceeded into the next stage of pre-flight acceptance, likely the final more step before a tethered static fire.

Routine for all Falcon rockets, SpaceX’s exceptionally rigorous practice of static firing all hardware at least once (and often several times) before launch has unsurprisingly held firm as the company proceeds towards integrated Starhopper and Starship flight tests. Despite the fact that Raptor SN06 completed a static fire as recently July 10th, SpaceX will very likely put Starhopper and its newly-installed Raptor through yet another pre-flight static fire, perhaps its fourth or fifth test this month.

This atlas of human CoRSIVs,” they write, “provides a resource for future population-based investigations into how interindividual epigenetic variation modulates risk of disease,” and may well transform understanding of the causes of illness in the human body.

There’s no way to store toxic coal waste that’s completely safe. There’s also no way to mine and burn coal that doesn’t threaten communities, our waterways and our climate. Duke needs to stop burning coal, clean up its toxic mess, and invest in abundant, affordable clean energy sources like solar and wind. #2048istoolate #BeyondCoal #YEARSproject with Sierra Club.

Any major breakthrough in extending human life would drastically alter population projections. The social effects, while obviously huge, would depend on whether the years of senility were prolonged, too; whether women’s age at menopause would increase; and how families would be structured if many generations were alive at the same time. Expensive treatments to extend human lives could also have implications for inequality; as in many other areas of technology, the wealthy would be most able to afford such services.

Almost everyone would welcome an extension of their healthy lifespan, and some scientists are looking at increasingly extreme ways to achieve that. But any major breakthrough in this area could have unwanted and far-reaching demographic, social, and economic implications.

CAMBRIDGE – Humans have long sought the elixir of youth, so it is not surprising that even non-scientists closely follow the latest research into aging. But is what most people consider simply a fact of life actually a “disease” that can be cured? Or is there some insurmountable limit to the lifespan of human bodies?
