The porn came back to tumblr but the users didn't.

You'd hope they do but many are not implementable in a quick manner or to the scale we have achieved with space based services. The question was about if they all failed at once, which is why we are quite concerned about coronal mass ejection and other space weather that could knock out our space systems all at once.

There are ground based PNT/augmentation seeking to lessen reliance on GNSS/space based PNT.

The US considers some of these capabilities as critical infrastructure with limited alternatives. Some are unique like the ISS and Hubble.

Remarkably GNSS is one of the largest components of the space industry. Near everything has gps or timing requirements now. https://brycetech.com/reports/report-documents/Bryce_2019_Global_Space_Economy.png

There is the LEO sun synchronous 'neighbourhood' which has a high amount of traffic crossing near the poles that is a concern.

GEO could be considered a neighbourhood.

There is 'terrain' in space, just not what people typically think of.

If you are interested have a read of the csis space threat assessment. https://aerospace.csis.org/space-threat-assessment-2022/

• Banking would stop due to loss of timing from GNSS. This has immediate and global ramifications.
• Some disruption to air traffic control as space based ADSB is lost and only available near airports.
• Global sea shipping loses tracking. Most navigation. Global disruption to bulk international supply chains until inertial nav and alternates are reinstalled.
• Military communication and some crypto is lost. Many many intel sources are lost. Most guided munitions are hampered, deterrence is lost in some cases, likely leading to conflict sparking as adversaries try to make use of the more even power equations. SBRS no longer provides nuclear deterrence.
• Weather prediction is significantly impacted. This has flow on effects to logistics, insurance and risk management. Military operations and rescue services are significantly impacted.
• Hubble is lost.
• TESS, Kepler, Chandra etc are gone, setting back some fields of astronomy.
• Astronauts, cosmonauts and taikonauts die as the ISS and Tiangong are inhabited satellites. All research aboard is lost.

And how would you stop them?

I propose an alternative... Dreamchaser.

Uncomfortable as it might make you feel, The soyuz has been the most flown and reliable human rated spacecraft ever.

Also consider the cause of this problem is soyuz MS22 has been whacked by some debris. It could have whacked the Crew Dragon instead. Would you still go off then?

Spacecraft like soyuz are not designed or built for you to be able to jump out of them. Cosmonauts are also typically fairly weak after extended stays in microgravity so won't be doing stunts on reentry. There are also no parachutes aboard the ISS.

Im also wary of positive comments that might be paid endorsements.

But my health insurance only covers inpatient.
