Granted, but bad things happen to everyone else!

PartLab is very out dated, and probably cannot read .mu. I recommend not using it.

Artist's concept of Voyager 1 and Voyager 2 at the edge of the solar system. CREDIT: NASA/JPL-Caltech View full size image It will be another giant leap for mankind when NASA's Voyager 1 spacecraft becomes the first manmade object to venture past the solar system's edge and into the uncharted territory of interstellar space. But did this giant leap already occur? New data from the spacecraft indicate that the historic moment of its exit from the solar system might have come and gone two months ago. Scientists are crunching one more set of numbers to find out for sure. Voyager 1, which left Earth on Sept. 5, 1977, has since sped to a distance of 11.3 billion miles (18.2 billion kilometers) from the sun, making it the farthest afield of any manmade object. (It has 2 billion miles on its twin, Voyager 2, which took a longer route through the solar system.) Still phoning home (via radio transmissions) after 35 years, the Voyagers are the longest operating spacecraft in history. For two years now, data beamed back to Earth by Voyager 1 has hinted at its close approach to the edge of the solar system, a pressure boundary called the heliopause. At this boundary, the bubble of electrically charged particles blowing outward from the sun (called the heliosphere) exactly counterbalances the inward pressure of the gas and dust from interstellar space, causing equilibrium between the two. But scientists have had trouble figuring out what, exactly, happens at or near this boundary  making it hard to tell whether Voyager has crossed it. In 2010, Voyager passed the point where the solar wind, a stream of charged particles flowing outward from the sun, seemed to reach the end of its leash. The probe's detectors indicated that the wind had suddenly died down, and all the surrounding solar particles were at a standstill. This "stagnation region" came as a surprise. Scientists had expected to see the solar wind veer sideways when it met the heliopause, like water hitting a wall, rather than screech to a halt. As Voyager scientists explained in a paper published last month in Nature, the perplexing collapse of the solar wind at the edge of the heliosphere left them without a working model for the outer solar system. "There is no well-established criteria of what constitutes exit from the heliosphere," Stamatios Krimigis, a space scientist at Johns Hopkins University and NASA principal investigator in charge of the Voyager spacecraft's Low-Energy Charged Particle instrument, told Life's Little Mysteries. "All theoretical models have been found wanting." However, Ed Roelof, also a space scientist at Johns Hopkins who works with Voyager 1 data, said that in any model of the heliopause, an object exiting through it should experience three changes: a sharp rise in the number of collisions with cosmic rays (high-energy particles from space), a dramatic drop in the number of collisions with charged particles from the sun, and a change in the direction of the surrounding magnetic field. Based on two of those criteria, Voyager 1 looks as if it passed through the heliopause at the end of the summer. Since May, the spacecraft has experienced a steady rise in the number of collisions with particles whose energies are greater than 70 Mega-electron-volts, indicating they are probably cosmic rays emanating from supernova explosions far beyond the solar system. The level of these cosmic ray collisions jumped significantly in late August. As first reported by Houston Chronicle science blogger Eric Berger, that jump coincided with another change in late August: The spacecraft also experienced a dramatic drop in the number of collisions with low-energy particles, which probably originated from the sun. [see graph] Rate at which Voyager 1 is being bombarded by particles such as protons. CREDIT: NASA View full size image In short, in late August, cosmic ray collisions sharply rose, and solar particle collisions sharply fell: two indicators of a transition through the heliopause. "Most scientists involved with Voyager 1 would agree that [these two criteria] have been sufficiently satisfied," said Ed Roelof, also a space scientist at Johns Hopkins who works with Voyager 1 data. To officially declare Voyager's crossing, the scientists need to check if the third condition holds. "Point 3 (the change in magnetic field direction to that of the interstellar field beyond the influence of the sun) is critical because, even though there is debate among astrophysicists as to what direction the field will lie in, it seems unlikely that it is the direction that we have been seeing at Voyager 1 throughout the most recent years," Roelof wrote in an email. "That is why we are all awaiting the analysis of the most recent magnetic field measurements from Voyager 1. We will be looking for the expected change to a new and steady direction. That would drop the third independent piece of evidence into place  if indeed that's what will be seen," he said. The scientists could not say when the magnetic field analysis would be finished. But when it is  and if it also indicates that the field's direction recently underwent a change  the world will know. "Once we have a consensus within the team we will inform NASA for a proper announcement," Krimigis said.

Granted, but you didn't make a wish, so you just wasted one. I wish I had a Beagle
-
Seen you a lot, especially in the Stock Community Base thread. 9/10

I love Duna too:
-
Pfft that's what sheild tanking's for!
-
This will be useful for my BACE edits and tweaks.

If you were the first person on mars, what would you say?

I agree there is no real story. Most stories have a beginning, middle, and end. I'm starting to sound like an English teacher.

OH SWEET JEBEDIAH IT KEEPS HAPPENING!

We would be able to see Jool as well if he didn't re size his images and then save them as JPEG.

Oops

LaydeeDem replied to hallothere's topic in KSP Fan Works
Cool. I was just wondering because that Kerbal looks almost exactly like the one in game. EDIT: What a way to waste my 1000'th post. -
Perhaps that was a poor remark to make. But the point still stands: Read books. That is the best way to get better at writing.

oh god why can i not stop laughing

Does anyone know GoDamit personally?
LaydeeDem replied to iamaphazael's topic in KSP1 Mods Discussions
Lol GoDammit. He got butthurt over stupid cartoon horses and deleted everything from the forums. Just use them. If he gets mad he can re-join the community. -
Third grade quality. It is very quick and doesn't have a very well thought out plot. It is very hard to read. Please read books. It really helps with writing.

It's not done yet silly. It attaches upside down and backwards.

I genrally begin turning at 10km and tilt to 45the degrees when I reach 500m/s. -
Hi. I'm the creator of the Astronaut Memorial Plaques. I have a surprise:
