The Code for the Apollo Moon Landings Is Now on GitHub

Suprisingly Funny the code for the Apollo Moon Landings Is Now on GitHub.
Computing has come a long way since the 1960s. The Apollo Guidance Computer (AGC) on board the Command Modules and Lunar Modules of the Apollo missions had about as much processing power as a simple electronic calculator. Yet through ingenuity—and thousands and thousands of lines of code—NASA and MIT engineers succeeded in safely landing a person on the moon.
The MIT Instrumentation Laboratory had to develop a new type of software technology for the Apollo space program. Core rope memory, a now antiquated form of read-only memory, was used with a unique assembly programming language to write the code that ran the Apollo Guidance Computer.
 












 
On July 7, however, former NASA intern Chris Garry uploaded the entire AGC software to the code-sharing site GitHub, making the information available to thousands more people. And it wasn't long until the folks on thesubreddit r/ProgrammerHumor got ahold of it and started picking it apart

As interest in the code exploded, people soon realized that the comments and labels left by the original coders, full of jokes and cultural references, are more amusing than the software instructions themselves. The instructions for the master ignition burn is titled, BURN_BABY_BURN- -MASTER_IGNITION_ROUTINE, for example. There is even an explanation of the name for the burn sequence




The effort made the code available to any researcher or hobbyist who wanted to explore it. Burkey himself even used the software to create a simulation of the AGC:

Juno (JUpiter Near-polar Orbiter) in Kerbal Space Program



Kerbal Space Program

Kerbal Space Program is hard. Why? Because real life is hard. You know how people always say “It’s not rocket science” in that annoying, pedantic tone? Well in this case, KSP is quite literally rocket science.
 Kerbal Space Program is one of the best of its kind. It’s an adult Lego set (or K’Nex set) given life. It’s creative, it’s complicated, and when you succeed in KSP it’s not because the game let you succeed—it’s because you actually learned something new and applied those concepts appropriately.

JUNO & Amateur radio operators around the world ....

As NASA's Jupiter-bound Juno spacecraft swung past Earth on Oct. 9, 2013, amateur radio operators around the world sent a Morse Code "HI" to the spacecraft. Would Juno hear their call?



Published on Dec 10, 2013 During its close flyby of Earth, NASA's Jupiter-bound Juno spacecraft listened for a communication from amateur radio operators transmitting from locations around the world. This video clip depicts results, the "dits" and the "dahs," of this high-flying social experiment. The full image caption for this movie is available at: http://photojournal.jpl.nasa.gov/cata... A four-minute documentary depicting the efforts of a few of the amateur radio operators who participated in the event can be seen at: http://youtu.be/_yqHy_MpNiQ

Soyuz Gets a Makeover



Soyuz-MS will now sport a powerful communications system, dubbed EKTS, which can connect the crew to mission control in Korolev near Moscow via satellite. Previously, cosmonauts and astronauts on Soyuz could talk to their peers on the ground only when in direct view of ground stations on the Russian territory. The large antenna array of the EKTS system "on the roof" of the Soyuz-MS is the most prominent new feature on the ship's exterior. Thanks to three available Russian Luch-5 satellites, the crew will be able to stay in touch with mission control around 83 percent of the time each day. The Soyuz will be also able to communicate via American TDRS and European DRS satellites.

The CPU from the original PlayStation is guiding the New Horizons space probe

You probably already know that your smartphone is more powerful than the computers used to land astronauts on the Moon. But did you know that the processor used in the original Sony PlayStation  is guiding  the New Horizons space probe. Yep, the same Sony PlayStation   MIPS R3000 CPU

The launch of the Es’Hail-2 satellite into a geostationary orbit at 25.5 degrees East is planned for December 2016. The coverage area of the amateur radio Narrowband (NB) and Wideband (WB) transponders should extend from Brazil to Thailand.


 
 
 
Es'hail-2 coverage area

Es’hail-2 coverage area

Es’hail 2 will carry two “Phase 4” amateur radio non-inverting transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.
Narrowband Linear transponder
 2400.050 -  2400.300 MHz Uplink
10489.550 - 10489.800 MHz Downlink

Wideband digital transponder
 2401.500 -  2409.500 MHz Uplink
10491.000 - 10499.000 MHz Downlink
Equipment requirements:
X-Band 10 GHz Downlink:
– 89 cm dishes in rainy areas at EOC like Brazil or Thailand
– 60 cm around coverage peak
– 75 cm dishes at peak -2dB
– NB: linear vertical polarisation
– WB: linear horizontal polarisation
S-Band 2.4 GHz NB-Uplink:
– narrow band modes like SSB, CW
– 5W nominal Uplink power (22.5 dBi antenna gain, 75cm dish)
– RHCP polarisation
S-Band 2.4 GHz WB-Uplink (DATV):
– wide band modes, DVB-S2
– peak EIRP of 53 dBW (2.4m dish and 100W) required
– RHCP polarisation

Tomsk-TPU-120 CubeSat Video

The Russian space agency Roscosmos has released a video of the Tomsk-TPU-120 CubeSat commemorative transmission from the International Space Station.
The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and is the world’s first space vehicle with a 3D-printed structure. It was launched from Baikonur to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel. It will be deployed by hand during a future Russian spacewalk (EVA), which is why unlike other CubeSats this one has a handle. The call sign of the satellite is RS4S.


Tomsk-TPU-120 CubeSat Callsign RS4S


In May 2016 the Tomsk Polytechnic University celebrated its 120th anniversary. As part of the celebrations on May 10/11 the Tomsk-TPU-120 was activated in the ISS and transmitted a greeting to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.
The greeting message was transmitted once a minute on 437.025 MHz FM. One of the Kenwood transceivers on the ISS provided a cross-band relay, re-transmitting the signal on 145.800 MHz FM.
The video, recorded in the Russian ISS Service Module, shows the CubeSat and the amateur radio station.

ISRO Tests Reusable Space Shuttle

 
Published on May 22, 2016 by India Today  @ youtube India Today
In a significant step towards developing a full fledged reusable launch vehicle, Indian Space Research Organisation tested a sleek winged prototype through a short test flight. The first such flight which is a technology demonstrator has been launched from the Satish Dhawan Space Centre in Sriharikotta. The idea to develop a vehicle with delta wings and an angled tail fin is to fly into space and land on earth like an aircraft. This will help cut cost satellite launches by 10 times and an advanced version of the vehicle could also be used for manned missions as well.

Low cost APRS !!


I had no transmitter module, to test my new Arduino sketch except the low
cost JMR-TX1 module. For my surprise it works like a charm and succeeded
to transmit packet frames without missing any,  just like a robust FM transmitter
module !!! .
On spectrum analyzer I noticed a lot of noise, but a simple output filter can
boost using of this cheap  low power module for more lab and field experiments.
