The boundary (black arrows in above WAC mosaic) with an older (3.5 billion years) red mare is only 10 km to the north. The landing site is on a blue mare (higher titanium) thought to be about 3.0 billion years old. The presence of ilmenite (FeTiO 3 ) results in lower reflectance and a 'lessred' color thus the blue basalts. Basalts on the Moon (same on Earth) are composed mainly of two minerals, pyroxene and plagioclase, though olivine and ilmenite can sometimes occur in significant amounts. Lunar mare basalts are divided into two main spectral (color) types: 'red' and 'blue' (blue is perhaps a misnomer, think 'less red'). Wrinkle ridges are common on the Moon, Mercury and Mars. Previous image Next image The ocean’s color has changed significantly over the last 20 years, and the global trend is likely a consequence of human-induced climate change, report scientists at MIT, the National. Geological Survey and MODIS data from LANCE/EOSDIS Rapid Response. A large scale wrinkle ridge (~100 km long, 10 km wide) cuts across the area and was formed as tectonic stress caused the volcanic layers to buckle and break along faults. Image: NASA and Joshua Stevens, using Landsat data from the U.S. The lander set down about 60 meters east of the rim of a 450 meter diameter impact crater (40 meters deep) on a thick deposit of volcanic materials. By comparing the before and after landing site images, the LROC team confirmed the position of the lander and rover, and derived accurate map coordinates for the lander (44.1214°N, 340.4884☎, 2640 meters elevation ).

The 1984 image shows the lake nearly full, compared to 37 percent full in the 2016 image. Since the rover is close to the size of a pixel, how can we be sure we are seeing the rover and not a comparably sized boulder? Fortuitously, the NAC acquired a 'before' image (M1127248516R) of the landing site, with nearly identical lighting, on 30 June 2013. Lake Mead, the largest reservoir in the U.S., has fallen to the lowest level since it began filling in the 1930s, the result of 16 years of drought in the Colorado River Basin. The rover is only about 150 cm wide, yet it shows up in the NAC images for two reasons: the solar panels are very effective at reflecting light so the rover shows up as two bright pixels, and the Sun is setting thus the rover casts a distinct shadow (as does the lander). At this time LRO was at an altitude of ~150 km above the site, and the pixel size was 150 cm. The highest resolution image was possible when LRO was nearly overhead on 25 December 03:52:49 UT (24 December 22:52:49 EST).

Ten days later on 24 December, LRO approached the landing site, and LROC was able to acquire a series of six LROC Narrow Angle Camera ( NAC ) image pairs during the next 36 hours (19 orbits). At the time of the landing LRO's orbit was far from the landing site so images of the landing were not possible. Soon after landing, a small rover named Yutu (or Jade Rabbit in English) was deployed and took its first tentative drive onto the airless regolith. Chang'e 3 landed on Mare Imbrium (Sea of Rains) just east of a 450 m diameter impact crater on 14 December 2013.

Join our free newsletter for weekly updates on the coolest innovations improving our lives and saving our planet. … We’re aiming high to demonstrate the kinds of energy-saving, emissions-reducing technologies the aviation industry needs.” … The X-66A will help shape the future of aviation, a new era where aircraft are greener, cleaner, and quieter, and create new possibilities for the flying public and American industry alike.”īob Pearce, associate administrator for NASA’s Aeronautics Research Mission Directorate, said, “To reach our goal of net-zero aviation emissions by 2050, we need transformative aircraft concepts like the ones we’re flying on the X-66A. In a press release, NASA Administrator Bill Nelson said, “At NASA, our eyes are not just focused on stars. When combined with other technological advancements, Boeing’s TTBW could result in as much as 30% less fuel consumption and reduced emissions as compared to today’s best-in-class planes, according to NASA. Good News Network reported that single-aisle commercial planes are responsible for almost 50% of global aviation emissions, and the National Oceanic and Atmospheric Administration adds that aviation accounts for 3.5% of all sources of Earth’s rising temperatures caused by human activities. The technology could go a long way in mitigating the effect of commercial aviation on the environment. The X-66A is being designed to improve fuel efficiency in commercial aviation and is the first plane focused on helping the U.S.
