Observations on aerospace sciences and technologies. Aerospace around the Bay. What happened to that e-journal? May 24, 2014. You know, the one that started a couple of months ago? Oh, you mean that. Was a victim of a hectic schedule for late April and early May 2014, along with urgent tasks on my day job. The Silicon Valley Space Center was running the Space Entrepreneurship Series, a set of four meetings, mostly in May. (I wrote an open invitation inviting aspiring space entrepreneurs. For now, it is o...

Observations on aerospace sciences and technologies. Aerospace around the Bay. Apollo 11 — when tech needed innovation and a bit of piloting. July 20, 2014. By today’s standards, the landing by humans on the Moon was technologically primitive. The landers that preceded Apollo to the Moon did not have digital computers. The Surveyor series of landers had servos, which fed back to various spacecraft systems, resulting in soft landings. Apollo Guidance Computer and display/keypad. And yet, with all the tech...

Observations on aerospace sciences and technologies. Aerospace around the Bay. Satellites: The Very Small. Small satellites are roughly classed as follows:. 100 to 500 kg (220 to 1,100 lb). 10 to 100 kg (22 to 220 lb). 1 to 10 kg (2.2 to 22 lb). 01 to 1 kg (0.22 to 2.2 lb). 001 to 0.1 kg (0.022 to 0.22 lb). This page focuses primarily on micro-, nano-, and picosatellites. An example of femtosatellites are KickSat Sprites (“chipsats”), but their launching container is a nanosatellite.

Observations on aerospace sciences and technologies. Aerospace around the Bay. June 14, 2014. SpaceX unveiled the manned version of the Dragon capsule on Thursday evening, May 29. (Yes, about 2 weeks ago. [ I’ve been busy. If you missed it, here is how SpaceX described Dragon V2. Judging from Internet reaction, people seem to be enamoured with it. You can read reactions to it elsewhere. I’ll give you my impression. A lander for Mars? If the capsule is to be reusable on Mars, it probably is going to be po...

Observations on aerospace sciences and technologies. Aerospace around the Bay. Monthly Archives: December 2013. December 31, 2013. As 2013 draws to a close, I’ve been doing the strangest thing I can imagine. I’ve been writing a page on balloons and rockets into space. It is by no means one of my more favored topics. In fact, writing this up feels strange. But given some space-oriented discussion questions I had seen in the last days, I felt I needed to set the physics and math straight. This year, 2013, ...

As a member of the AIAA San Francisco Section council, I’ve been exposed to a lot of aerospace-oriented groups that make themselves available to either specialists in aerospace or the general public. There is a wealth of such activity in the Bay area. It is a major challenge to catalog them all. AIAA San Francisco Section. Http:/ www.aiaa-sf.org. Mountain View, CA. Http:/ www.svsbr.org.

A text-based countdown script in Python | RocketSciRick
https://rocketscirick.wordpress.com/2014/06/25/a-text-based-countdown-script-in-python
Observations on aerospace sciences and technologies. Aerospace around the Bay. A text-based countdown script in Python. June 25, 2014. Problem: You want to count down to an event (e.g., a rocket launch). But the web-based animated countdown consumes too much screen space and battery power (i.e., your laptop’s fan turns on when you go to that web page). Solution: a text-based countdown in a small shell or console window. This one, down.py. Is written in Python 3. The project on GitHub is called DownPy.
