Readers!
 

The final week of my annual February birthday month fund-raising campaign for Behind the Black has begun. I continue to be overwhelmed by the outpouring of support, including numerous donations and a surge of new subscribers willing to commit to donating anywhere from $2 to $25 per month. Wow! The numbers are too many to send out individual thank you’s, so please forgive me for thanking you all with this one announcement.

 

The campaign however must go on, especially because I have added more regular features to my daily workload. In addition to my daily never-ending reporting on space exploration and science, my regular launch reports, my monthly sunspot updates, the regular cool images, and the evening pauses I post each evening, I have now added a daily weekday post I have entitled "Today's blacklisted American." Its goal is not to discuss policy or politics, but to note the endless examples occurring across the United States where some jack-booted thug or thugs think it is proper and acceptable to censor, blackball, cancel, and destroy an innocent American, merely because that American has expressed or holds an opinion or is of a race or religion that is no longer considered acceptable to the dominant leftist and bigoted culture. I want to make clear to every American that a large number of your fellow citizens no longer believe in the enlightened concept of freedom of speech or the idea of treating each person by the quality of their character.

 

Instead, they wish to shut you up, and oppress you if you happen to disagree with them or have the wrong skin color. This evil must be exposed.

 

To continue to do this into the foreseeable future however I need your support. If you are one of those millions who read Behind the Black each month, please consider donating or subscribing. Regular readers can support Behind The Black with a contribution via paypal:

Astronaut treated for blood clot on ISS

In a first, an unnamed astronaut had been treated for a blood clot while on a six-month mission on ISS sometime in the last few years.

Ultrasound examinations of the astronauts’ internal jugular veins were performed at scheduled times in different positions during the mission. Results of the ultrasound performed about two months into the mission revealed a suspected obstructive left internal jugular venous thrombosis (blood clot) in one astronaut. The astronaut, guided in real time and interpreted by two independent radiologists on earth, performed a follow-up ultrasound, which confirmed the suspicion.

Since NASA had not encountered this condition in space before, multiple specialty discussions weighed the unknown risks of the clot traveling and blocking a vessel against anticoagulation therapy in microgravity. The space station pharmacy had 20 vials containing 300 mg of injectable enoxaparin (a heparin-like blood thinner), but no anticoagulation-reversal drug. The injections posed their own challenges – syringes are a limited commodity, and drawing liquids from vials is a significant challenge because of surface-tension effects.

The astronaut began treatment with the enoxaparin, initially at a higher dose that was reduced after 33 days to make it last until an oral anticoagulant (apixaban) could arrive via a supply spacecraft. Anticoagulation-reversing agents were also sent.

Although the size of the clot progressively shrank and blood flow through the affected internal jugular segment could be induced at day 47, spontaneous blood flow was still absent after 90 days of anticoagulation treatment. The astronaut took apixaban until four days before the return to Earth.

On landing, an ultrasound showed the remaining clot flattened to the vessel walls with no need for further anticoagulation. It was present for 24 hours after landing and gone 10 days later. Six months after returning to Earth, the astronaut remained asymptomatic.

What is not known is whether weightlessness caused the clot, or whether it would have occurred regardless. The former seems very possible as the astronaut had no history of such clots, and returned to normal almost immediately upon return to Earth. As noted at the link, more research is necessary, especially in anticipation of long interplanetary flights.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.


He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
