Asteroid 2010 WC9 will make a close approach to Earth today (5/15/18)
at 3:04 p.m. PDT (6:04 p.m. EDT, 22:04 UTC). At the time of closest
approach, the asteroid will be no closer to Earth’s surface than about
120,000 miles (200,000 kilometers), which is about half the distance
between Earth and the Moon. 2010 WC9 is about 200 to 400 feet (50 to 120
meters) across. The asteroid's velocity at the time of closest approach
will be about 29,000 mph (8 miles per second, 12.8 kilometers per
second). This flyby is the closest approach 2010 WC9 will make to Earth
for at least two centuries.
Asteroid 2010 WC9 was discovered on Nov. 30, 2010, by the
NASA-sponsored Catalina Sky Survey near Tucson, Arizona, and was tracked
for about 10 days before it faded from view. Orbit calculations in 2010
ruled out any chance that the asteroid could pose a threat to our
planet in 2018, but the distance of this year's close approach could not
be predicted precisely until the asteroid was detected again last week
as it approached our planet once again.

The Code for the Apollo Moon Landings Is Now on GitHub
Suprisingly Funny the code for the Apollo Moon Landings Is Now on GitHub.
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:

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

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

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
