It's not rocket science. July 20, 2016. July 20, 2016. Forty-seven years ago today, Americans landed on the moon. I was five years old and still remember every bit of it, including my parents letting me stay up way past my bedtime to watch an unassuming man from Wapokoneta, OH, step out and take a stroll. For the closest thing you may ever have to a front-row seat, check out these painstakingly synchronized audio and video loops from. Would that we might muster the will to do such things again. Allowed a...

So Many Choices, So Few Dollars | Hohmann Transfer

https://hohmanntransfer.wordpress.com/2012/06/28/so-many-choices-so-few-dollars-17

Jun 28, 2012. So Many Choices, So Few Dollars. First there was WISE. The NASA space telescope that scanned the sky in infrared. Besides locating many brown dwarfs, under the NEOWISE. Program, it also found thousands of new asteroids including 129 near-Earth ones, 22 of which are potentially hazardous. This was an excellent proof-of-concept showing even a small space telescope could discover hundreds of new, potentially hazardous objects. Then came the unveiling of Planetary Resources. To me, this all fee...

Chronicles of someone trying to get off the rock. What is an astrowright? What the world thinks spacecraft scientists/engineers do…. Well, ramping up to the birth of our second child, (daughter Sloane on 08/05/14! I’ve been completely absorbed by family by night and the incredible clip at work at Bigelow Aerospace by day. -And amidst it all, I’ll admit that there is a visceral seduction in the elbow-grease-saturated chaos.

Chronicles of someone trying to get off the rock. What is an astrowright? What is an astrowright? Two NASA astronauts participate in construction and maintenance activities outside the International Space Station; 21 May 2010. Credit: NASA. So, what does “astrowright” really mean? To me, the word represents a little more than an astronaut. So, I see an astrowright as:. Person whose creations and/or work directly relate to space and space exploration. Is a person who wants to. In space – to. I got your co...

Chronicles of someone trying to get off the rock. What is an astrowright? My planetary science and space exploration research falls into roughly five categories – geomorphology of exotic sediment transport mechanisms ( dust devils. Migration), remote sensing/planetary resource utilization ( ISRU. Cryosphere/hydrology research ( glaciology. And human factors research in space exploration.

Musks vision för Mars kan locka makten. I Fokus skriver jag om planeten Mars. Och försöken att strukturera en plan för att skicka människor till den svårhanterliga miljön. De mer storslagna visionerna kan faktiskt få det politiska stöd som tills nu saknats för Mars-resor. Elefanten i rummet är SLS. De gigantiska raketer som Nasa utvecklar för framtida resor till Mars. Det slukar redan nu alltför mycket av Nasas budget enligt kritikerna och många undrar varför man inte kan låta privata företag som Elo...

Polymath: April 2015

http://exoscientist.blogspot.com/2015_04_01_archive.html

Friday, April 17, 2015. Hovering capability for the reusable Falcon 9. We have now two landing attempts by the reusable F9 first stage onto the SpaceX barge. Both were unsuccessful. From the appearance of both failed landings it would appear that the capability to hover could have made both landings successful:. About this latest test landing, Elon Musk in a Tweet has acknowledged that not being able to hover will result in a high g landing:. Elon Musk (@elonmusk) April 15, 2015. Post could also be used ...

Polymath: Merlin 1A engine for a hovering Falcon 9 v1.1 first stage.

Tuesday, August 26, 2014. Merlin 1A engine for a hovering Falcon 9 v1.1 first stage. More on Grasshopper’s “Johnny Cash hover slam” test. Http:/ www.newspacejournal.com/2013/03/09/more-on-grasshoppers-johnny-cash-hover-slam-test/. Still for safety reasons I would prefer a stage that did have the capability to hover. One concern without the ability to hover for example would be unexpected large changes in wind speed and direction known as wind shear. While wind shear is particularly dangerous for aircraft...
