This video describes many times when space agencies, mostly NASA, purposely crashed a spacecraft into a planet. Crashing spacecraft into the moon before landing procedures were figured out, crashing an S4B into the moon to set off seismic waves, crashing spacecraft into Venus, and ditching the Galileo spacecraft into Jupiter. Interestingly, I can think of 3 more deliberate spacecraft crashes not mentioned in this clip. Guess them?

An Atmosphere Around the Moon? NASA Research Suggests Significant Atmosphere in Lunar Past and Possible Source of Lunar Water by NASA's Marshall Space Flight Center Via Flickr: Looking up at the Moon at night, Earth's closest neighbor appears in shades of gray and white; a dry desert in the vacuum of space, inactive and dead for billions of years. Like many things, though, with the Moon, there is so much more than what meets the eye. Research completed by NASA Marshall Space Flight Center planetary volcanologist Debra Needham in Huntsville, Alabama, and planetary scientist David Kring at the Lunar and Planetary Institute in Houston, Texas, suggests that billions of years ago, the Moon actually had an atmosphere. The ancient lunar atmosphere was thicker than the atmosphere of Mars today and was likely capable of weathering rocks and producing windstorms. Perhaps most importantly, it could be a source for some, if not all, of the water detected on the Moon. Image credit: NASA/JPL/USGS Read more NASA Media Usage Guidelines

15 años después localizaron el lugar de un impacto lunar
El impacto del LCROSS levantó una nube de regolito que contenía abundante agua (5,6 % en masa), junto con pequeñas cantidades de dióxido de carbono, dióxido de azufre, metano y amoníaco.
En 2009, la NASA estrelló intencionalmente una nave espacial en la Luna y utilizó una pequeña nave espacial que la seguía para observar los resultados: el Satélite de Observación y Detección de Cráteres Lunares (LCROSS, por sus siglas en inglés) fue diseñado para buscar agua lunar congelada y otros volátiles en el regolito lunar sacándolos de la Luna. Los volátiles son materiales que se…
Even over de rotatieassen van Aarde en Maan

De Griekse filosoof Heraclites zei het al in de Oudheid: Panta rhei, oftewel alles is in beweging. Dat geldt niet alleen voor rivieren – je kunt niet twee keer in dezelfde rivier stappen, zei Heraclites ergens rond 500 voor Christus – maar ook voor rotatieassen. Yep, twee berichten kwamen recentelijk tot mij, de ene over de rotatieas van de maan, de ander over de rotatieas van de aarde. Wat blijkt:
dat de rotatieas van de maan ongeveer drie miljard jaar geleden een beetje is gekanteld, zo blijkt uit onderzoek aan de verdeling van het ijs dat in diepe kraters rond de noord- en zuidpool van de maan is gelegen. Dat ijs blijkt niet gecentreerd te zijn rond de huidige polen, maar er 200 kilometer naast. Vanaf de aarde gezien is de noordkant van de maan een graad of vijf naar achteren gekanteld, en de zuidkant evenveel naar voren gekomen en dat schijnt in pakweg een miljard jaar te zijn gebeurd. Bij die verschoven zuidpool drie miljard jaar geleden sloeg op 9 oktober 2009 de LCROSS sonde te pletter, de plek waar nu de krater Cabeus A ligt. Bron: NASA.
dat de rotatieas van de aarde ook opschuift – alles beweegt zoals Heraclites zo’n 2500 jaar geleden al stelde – en dat die verschuiving sinds het jaar 2000 een bepaalde kant opgaat en de oorzaak van die verschuiving in richting komt door… de mens! Nee het is geen verlate 1 aprilgrap, onderzoek van wetenschappers van NASA’s Jet Propulsion Laboratory (JPL) laat zien dat de richting bepaald wordt door twee dingen, te weten het smelten van de ijskappen of Groenland en West-Antartica én de verdeling van de watermassa’s op land en zee. En waar ontstaan die twee dingen weer door: door de opwarming van de aarde, die door de mens versterkt wordt. Hieronder een afbeelding waarop de verschuiving in de richting van de beweging van de rotatieas van de aarde goed te zien is.

Mỹ công bố hình ảnh mới nhất về trái đất
Mỹ công bố hình ảnh mới nhất về trái đất
Theo tin từ trang mạng Space của Mỹ, trái đất được gọi là “viên đạn màu xanh” chưa bao giờ mất đi sự hấp dẫn của nó, hiện tại, hai thiết bị thăm dò đã chụp được những hình ảnh mới nhất của trái đất từ quỹ đạo mặt trăng, từ đó sẽ có một cánh nhìn toàn diện hơn về trái đất. Thiết bị vẽ bản đồ khoáng vật mặt trăng (Moon Mineralogy Mapper) do cơ quan hàng không vũ trụ Mỹ (NASA) chế tạo là thiết bị…
