Simulation position and velocity of Sun, Earth, and Moon bodies brings errors. An attempt was done to use NASA’s data – some of DEXXX files are available. Minor errors were fixed in the C version of the code (convert.c) done by David Hoffman from a NASA Jonson Space Center. Looks like porting code from Fortran was a source of errors. Some memory was corrupted around R1 and R2 constant (array of 400 elements initialized, but line “for ( i=0 ; i

Over the weekend, I was reminded of just how fascinated people are by the Moon. While attending a birthday party that included 15 small children, one of the youngest party-goers, a one-year old, pointed up into the late afternoon sky and said "Moon!" Barely old enough to stand and only possessing a few words, she knew this unmistakable beacon in the sky. Her own delight was reflected in her father's face, who I could see had taught her the word and was pleased by her instant recognition.

A lunar mission requires a stiff and strong structure to support the spacecraft during launch. Stiffness is essential to preclude coupling with the launch vehicle, which could impact launch performance. Strength is essential to survive shaking and acceleration at launch, which produce a g-force of 6.

The E-111 airplane for the Google Lunar X Prize Competition was officially renamed today as I.A.R - 111. I.A.R is a Romanian build series of airplanes since 1925. It is a great honor and obligation for ARCA to contribute to the I.A.R. tradition. Among the I.A.R. airplanes we mention: I.A.R. - 11CV, I.A.R. - 80, I.A.R. - 93, I.A.R. - 99.
More about I.A.R. series here.

Team Puli Space luckily receives quite a lot of media attention, although this mostly manifests in Hungary. However, around here we’re booming: we have been invited to radio interviews, have appeared in nearly all prominent national newspapers, and have been television in talk shows and even in the evening news on major channels. Take a moment and get a scoop of the media appearances of the Team Puli.

Intro
This is a continuation of our discussion on how we are going to pay for our GLXP entry. Previously, we talked about the nanosat launcher challenge contracting we are doing and sponsorship we are raising. We were hoping to set something that would be useful to our readers and potentially other teams. as we have said, we have no desire to give away all our secrets. However, we do like the idea of there being a real race rather than an anointing of the One True Team. If we can help in a small part to make that happen, we will have done our part.
