August 2017 lunar eclipse. A partial lunar eclipse took place at the Moon's descending node on the evening of 7 August and the morning pre-dawn on 8 August 2017, the second of two lunar eclipses in 2017. The Moon was only slightly covered by the Earth's umbral shadow at maximum eclipse. The Moon's apparent diameter was smaller because the ...
On 16 November 2019, the Failure Analysis Committee released its report to the Space Commission, concluding that the crash was caused by a software glitch. [50] Phase One of descent the Rough Braking Phase from an altitude of 30 km to 7.4 km above the Moon's surface went as intended with velocity being reduced from 1683 m/s to 146 m/s.

The Chandrayaan programme (/ ˌ tʃ ʌ n d r ə ˈ j ɑː n / CHUN-drə-YAHN) (Sanskrit: Candra 'Moon', Yāna 'Craft, Vehicle', pronunciation ⓘ) [4] [5] also known as the Indian Lunar Exploration Programme is an ongoing series of outer space missions by the Indian Space Research Organization (ISRO) for the exploration of the Moon.
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°). [3] This means that the lunar hemisphere facing Earth—the near side —is completely sunlit and appears as an ...
The Chinese Lunar Exploration Program (CLEP; Chinese: 中国探月工程; pinyin: Zhōngguó Tànyuè Gōngchéng), also known as the Chang'e Project (Chinese: 嫦娥工程; pinyin: Cháng'é Gōngchéng) after the Chinese Moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA).
Based on observations spanning 80 days, ʻOumuamua's orbital eccentricity is 1.20, the highest ever observed [65] [10] until 2I/Borisov was discovered in August 2019. An eccentricity exceeding 1.0 means an object exceeds the Sun's escape velocity , is not bound to the Solar System, and may escape to interstellar space.
Catalog # (SE5000) 9546. The solar eclipse of August 21, 2017, dubbed the " Great American Eclipse " by some media, [ 1 ] was a total solar eclipse visible within a band that spanned the contiguous United States from the Pacific to the Atlantic coasts. It was also visible as a partial solar eclipse from as far north as Nunavut in northern ...
