[漢羅] Stickney 隕石坑

Stickney 隕石坑是火衛一 Phobos 頂懸上大 ê 隕石坑，是用 數學家 Chloe Angeline Stickney Hall，嘛是天文學家 Asaph Hall in 某 ê 名 kā 號--ê。 Asaph Hall tī 1877 年 ê 時陣，發現 火星 ê 兩粒衛星。 Stickney 隕石坑 ê 直徑超過 9 公里，差不多是 火衛一 Phobos 直徑 ê 一半。 會攏出遮爾大隕石坑--ê，應該嘛差不多會 kā 這粒細粒衛星攏甲欲散去。 這張 Stickney 隕石坑 kah 伊四箍圍仔 ê 加強色彩影像，是 火星偵察軌道衛星 tī 2008 年 3 月 ùi 火衛一 Phobos 附近 6000 公里遠 ê 所在，用 HiRISE kha-mé-lah 翕--ê。 火衛一 Phobos 就敢若小行星 仝款，伊 ê 表面重力是比地球重力 ê 1/1000 閣較細。 毋過伊表面一逝一逝 ê 痕跡暗示講，較散 ê 物質會沓沓仔落到隕石坑內底。 隕石坑附近 ê 藍光區，可能是較新 ê 表面。 是講隕石坑表面彼寡奇怪 ê 溝仔是按怎生出來--ê，實在是足神祕--ê。 有可能 kah 近火衛軌道 受著 ê 潮汐力，嘛有可能 kah 隕石坑形成 ê 相挵有關。

[English] Stickney Crater

Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877. Over 9 kilometers across, Stickney is nearly half the diameter of Phobos itself, so large that the impact that blasted out the crater likely came close to shattering the tiny moon. This enhanced-color image of Stickney and surroundings was recorded by the HiRISE camera onboard the Mars Reconnaissance Orbiter as it passed within some six thousand kilometers of Phobos in March of 2008. Even though the surface gravity of asteroid-like Phobos is less than 1/1000th Earth's gravity, streaks suggest loose material slid down inside the crater walls over time. Light bluish regions near the crater's rim could indicate a relatively freshly exposed surface. The origin of the curious grooves along the surface is mysterious but may be related to tidal stresses experienced by close-orbiting Phobos or the crater-forming impact itself.
