Where on the Moon will the first crewed Artemis mission Land? While NASA is still deliberating on the exact location, they’ve chosen several candidate landing sites near the lunar south pole. This new image captured by the Lunar Reconnaissance Orbiter reveals what the astronauts might see out the window as they approach their destination.

NASA has granted mission extensions to eight different planetary missions, citing the continued excellent operations of the spacecraft, but more importantly, the sustained scientific productivity of these missions, “and the potential to deepen our knowledge and understanding of the solar system and beyond.” Each mission will be extended for three more years.
One of the most exciting extensions gives a new mission to the OSIRIS-REx spacecraft, sending it to one of the most infamous asteroids of them all, the potentially hazardous asteroid Apophis.

On Tuesday, December 1st, at 10:11 EST (07:00 PST) the Chang’e-5 sample return spacecraft landed safely on the Moon. This mission is the latest in China’s lunar exploration program, which is paving the way for the creation of a lunar outpost and a crewed mission by the 2030s. The day after it landed, the Lunar Reconnaissance Orbiter (LRO) passed over the site and acquired an image of the lander.

This may be one of the strangest craters you’ll ever see.
Ryder crater is located near the south pole of our Moon, and it has a bizarre oblong shape (approximately 13 x 17 km in size), with a ridge cutting across the middle.
The majority of impact craters are round. How did Ryder crater end up in this odd shape?

In 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO), the first mission to be sent by the US to the Moon in over a decade. Once there, the LRO conducted observations that led to some profound discoveries. For instance, in a series of permanently-shaded craters around the Moon’s South Pole-Aitken Basin, the probe confirmed the existence of abundant water ice.
Based on the temperature data obtained by the LRO of the Moon’s southern polar region, the ESA recently released a map of lunar water ice (see animation below) that will be accessible to future missions. This includes the ESA’s Package for Resource Observation and in-Situ Prospecting for Exploration, Commercial exploitation and Transportation (PROSPECT), which will be flown to the Moon by Russia’s Luna-27 lander in 2025.

On May 20th, 2018, the China National Space Agency (CNSA) launched the Queqiao spacecraft, the vehicle that would deliver the Chang’e-4 mission to the Moon. This vehicle was also responsible for transporting a lesser-known mission to the Moon, known as the Longjiang twin spacecraft. This package consisted of two satellites designed to fly in formation and validate technologies for low-frequency radio astronomy.
While Queqiao flew beyond the Moon to act as a communications relay for the Chang’e-4 lander, the Longjiang satellites were to enter orbit around the moon. On July 31st, 2019, after more than a year in operation, the Longjiang-2 satellite deorbited crashed on the lunar surface. And thanks to efforts spacecraft tracker Daniel Estévez and his colleagues, the Lunar Reconnaissance Orbiter (LRO) was able to photograph the impact site.

This image of the lunar highlands is from NASA’s Lunar Reconnaissance Orbiter. You’d need superhuman eyesight to spot it, but India’s crashed Vikram lander is in there somewhere. The lander attempted to land on the Moon on September 6th, but when it was only 2.1 km above the surface, within reach of its objective, ISRO (Indian Space Research Organization) lost contact with the spacecraft.

In addition to being the only solvent that is capable of supporting life, water is essential to life as we know it here on Earth. Because of this, finding deposits of water – whether in liquid form or as ice – on other planets is always exciting. Even where is not seen as a potential indication of life, the presence of water offers opportunities for exploration, scientific study, and even the creation of human outposts.
This has certainly been the case as far as the Moon and Mercury are concerned, where water ice was discovered in the permanently-shadowed cratered regions around the poles. But according to a new analysis of the data from the Lunar Reconnaissance Orbiter and the MESSENGER spacecraft, the Moon and Mercury may have significantly more water ice than previously thought.

The history of the Moon is a tale told by geology, apparent in its rocks, craters, and other surface features. For centuries, astronomers have studied the Moon from afar and for the past few decades, it has been visited by countless robotic missions. Between 1969 and 1972, a total of twelve astronauts walked on its surface, conducted lunar science, and brought samples of lunar rock back to Earth for study.
These efforts have taught us a lot about the things that have shaped the lunar surface, be they one-off events like the massive impact that formed the Shakleton crater to things that happened regularly throughout its 4.51 billion-year history. For instance, scientists recently discovered something unusual about the Antoniadi crater: a large boulder was perched on the rim of a smaller crater within after rolling about 1000 meters (1093 yards) downhill.

It’s always easier to show someone a picture of something rather than to use 1,000 words to explain it. The people at NASA’s Scientific Visualization Studio (SVS) know this, and they’re experts. Every year they release a simulation of the Moon that shows what the Moon will look like to us each day.
NASA’s Moon simulator uses images and data captured by the Lunar Reconnaissance Orbiter (LRO) to recreate the Moon on each hour of each day of each month in 2018. You can input any date and time to view the Moon (Dial-a-Moon) as it will appear at that time. You can also watch a video of the Moon over the course of the entire year. Along the way, you might learn something.
