It sounds like a super villain weapon.

If you manufacture there how do you recover it?

The Starfall capsule has enough deltaV to deorbit, a heat shield, and parachutes.

So you tell them where to deliver it (anywhere on the planet that its orbit goes over..), they tell you when it will be arriving, and it reenters and lands there.

Article about a recent test (launched on a Falcon 9):

Do they offer same day delivery ?

If you are not home to sign, it blasts off again onto orbit.

Presumably the same way we have always recovered payloads from space. Heat-shield + parachute. I'm assuming there would be some capability to do a retrograde maneuver so that the re-entey can be done when and where desired, rather than leaving it to the whims of pure drag.

The graphic shows it reentering the atmosphere.

You're not wrong! It looks that way because it's a reentry vehicle. You put this thing in a low orbit which decays over the course of a few weeks until it eventually falls from space, then you go find it.

They have thrusters and do controlled re-entry, at a location of their choosing.

The uppermost parts of the atmosphere are very dynamic, with changes in solar activity causing them to contract and expand on a scale of hours. And this is very significant for the amount of drag felt by re-entering objects. Because of this, if you slowly deorbit something naturally through drag, you are not going to be able to pick the destination, or even know where it ends up until very close to it falling down. So instead you intentionally lower the perigee so that it deorbits in a controlled manner.

Didn't know that, shouldn't have assumed. Wish I could fix my third sentence...

Thanks for the correction!

Doesn't sound dangerous at all.

Dropping stuff from space is inherently dangerous. Huge amounts of effort go into making it safe.

So you think these things will be delivered to new york ?
itishappy 3 days ago||
Not intentionally, of course, but they will be flying directly overhead a few times every day!

You realize they know how to land these things right? Are you aware?

I trust government agencies who are doing these things for science and research to do it safely, private companies owned by conmen who are probably operating under presidential pardons, not really.

I'm curious as to when the first space-grown semiconductor crystals will be put to use in fabs and what the possibilities are.

Will this mean that only governments and the military can afford to purchase next generation semiconductors which need ultra-pure silicon?

This is amazing. Especially for biotech. A robot can do biotech in microgravity.

It mentions that it provides weeks of power, presumably with solar on top - does it just passively decay or is there a prop system on this as well?

Just reading the headline I was expecting this to be some sort of health subscription

It did mention medications. Perhaps pharmaceutical companies will charge 20% more for medications that are produced in space vs those produced on Earth?

You can hate this man but he is doing things others don't even dream about. He almost makes them look easy.

Looks cool and if they could make chips in space, it will be beyond crazy. It will be over time and way over budget but in the end will be insanely profitable.

desireco42 3 days ago||
He essentially put a price on this, and now you can just factor this into manufacturing and if something can be made there and numbers make sense, it will be made there.

Pretty bad product name. Waitlessness Inc. perhaps

It would be nice if SpaceX published GNSS pseudodistance/carrier phase from all Starlink satellites. It would give excellent realtime tomographic information about the ionosphere...

Why is it called microgravity and not freefall? Cus afaik you are experiencing almost the same force of gravity as you would on the surface, you are just constantly falling.
BHSPitMonkey 3 days ago|
Among other reasons, because it's not specific enough. Skydiving is also free-falling yet it's not at all the same conditions you experience on the ISS. And it would be even more confusing to describe an object on a trans-planetary injection or a free trajectory between stars as "freefalling", since you've removed the singular frame of reference you need to "fall" toward.

i trust dan gelbart who is very skeptical that there are many really viable uses of manufacturing in space
