Computing: a modified version of the Internet's communications protocol, devised for interplanetary use, is being tested by spacecraft.(計算機工程：一個修改版的互聯網通訊協議正在太空船上進行測試，此協議專門用于行星間通訊。)

In 1967, a new type of radio telescope intended for the study of interplanetary scintillation came into operation.(1967年，一種新型的打算用于研究行星閃爍的射電望遠鏡投入了工作。)

The encounters occur under conditions of weak and steady southward Interplanetary Magnetic Field (IMF).(這兩次穿越是在弱而穩定的南向行星際磁場(IMF)條件下發生的。)

The Interplanetary Internet will use spacecraft that have completed their mission to create a backbone for the new network.(星際互聯網將使用已發射的航天器來構造新互聯網的主干網。)

Researchers plan to evaluate the likelihood of panspermia by studying whether microorganisms can survive an interplanetary journey.(研究人員打算研究：微生物是否可以在星際旅行中存活，并據以評估胚種說存在的可能性。)

Soon everyone will be dreaming of interplanetary travel again, he predicts.(他預測，很快每個人都會再次夢想星際旅行。)

Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space?(這些實驗能提供足夠深刻的見解，從而將把人送到星際空間的花費合理化嗎？)

This could compromise our ability to distinguish between interstellar dust and interplanetary dust.(這有可能危及我們區分星際塵埃和太陽系內塵埃的能力。)

The remnant nebular gas pervades the interplanetary space.(星云的殘余氣體充斥星際空間。)

In terms of density, the voyage from interplanetary to intergalactic space is more drastic than going from water into air.(以密度來說，從行星際到星系際空間的旅行，比從水進入空氣中還激烈。)
