wide angle: project icarus: reaching for interstellar space
广角:伊卡洛斯项目:延伸到星际空间
scientists think it will enter interstellar space in about four years.
科学家相信四年内它将进入星际空间
crossing into interstellar space would mean a sudden drop in the density of hot particles and an increase in the density of cold particles.
进入星际空间意味着热粒子的密度会突然降低而冷粒子的密度将升高。
or it could mean that voyager 1 has already crossed the heliopause. either way, the spacecraft becomes the first object in interstellar space created by intelligent life. that we know about.
my own view is that the first interstellar space mission will be targeted at one of the very nearest stars, probably one of closest half dozen systems.
我个人的看法是首个星际太空任务应该以最近最近的恒星中的一个为目标,可能是最近的几个星系之一。
for the crew of a spacecraft ramping up to light speed, interstellar space would appear highly compressed, thereby increasing the number of hydrogen atoms hitting the craft.
对宇宙飞船的船员来说,速度升高到光速,宇宙空间将被高度压缩,因此增加了撞击飞船的氢原子数量。
a continuous broadcast powerful enough to reach across interstellar space takes a huge amount of energy.
持续的广播足够到达星际空间,那要消耗巨大的能量。
it transforms the thin wisp of hydrogen gas that permeates interstellar space into an intense radiation beam that would kill humans within seconds and destroy the spacecraft's electronic instruments.
mission managers expect voyager 1 to leave our solar system and enter interstellar space in the next five years or so, with voyager 2 on track to enter interstellar space shortly after that.
