We Found the Perfect Spot to Land our Moon Rover

After an extensive selection process, we chose the mountainous area west of Nobile Crater at the Moon’s South Pole as the landing site for our first-ever robotic Moon rover. The Volatiles Investigating Polar Exploration Rover, or VIPER, will explore the Moon’s surface and subsurface in search of water and other resources beginning in late 2023. Thanks to past missions, such as satellites orbiting the Moon or impacting its surface, we know there is ice at the Moon’s poles. But how much? And where did it come from? VIPER aims to answer these questions and more by venturing into shadowed craters and visiting other areas of scientific interest over its 100-day mission. The findings will inform future landing sites under the Artemis program and help pave the way toward establishing a long-term human presence on the Moon. Here are five things to know:

The landing site is located just outside the western rim of Nobile Crater at the Moon’s South Pole.

The region has suitable lighting and terrain for our solar-powered rover to navigate.

VIPER will travel up to 15 miles in search of water and other resources.

Its traverse will change depending on what it finds, but it could look like this.

Drivers on Earth will tell the rover where to explore during its 100-day mission.

The VIPER mission is managed by our Ames Research Center in California's Silicon Valley. The approximately 1,000-pound rover will be delivered to the Moon by a commercial vendor as part of our Commercial Lunar Payload Services initiative, delivering science and technology payloads to and near the Moon.

Hurry! You Can Catch a Ride to Jupiter with NASA

Well, at least your name can.  

One of the planet Jupiter’s largest and most intriguing moons is called Europa. Evidence hints that beneath its icy shell, Europa hides an ocean of liquid water – more water than all of Earth’s oceans combined. In 2024, our Europa Clipper robotic spacecraft sets sail to take a closer look…and when it launches, your name can physically be aboard! Here’s how: 

NASA’s Message in a Bottle campaign invites people around the world to sign their names to a poem written by the U.S. Poet Laureate, Ada Limón. The poem connects the two water worlds — Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored.

The poem will be engraved on Europa Clipper, along with participants' names that will be physically etched onto microchips mounted on the spacecraft. Together, the poem and names will travel 1.8 billion miles to the Jupiter system.

Signing up is easy! Just go to this site to sign your name to the poem and get on board. You can send your name en español, too. Envía tu nombre aquí.

The Europa Clipper launch window opens in October 2024, but don’t wait – everyone’s names need to be received this year so they can be loaded onto the spacecraft in time. Sign up by Dec. 31, 2023.

We hope you’ll be riding along with us! Follow the mission at europa.nasa.gov.

In about 3 weeks, I’ll be attending Astronaut Training Experience at SpaceCamp as an educator! I’m so excited! Not bad for John, the world’s biggest 12 year old. Speaking of 12, that is also the number of former and current astronauts who have attended SpaceCamp. Astronaut Kate Rubins, who is on the ISS right NOW, attended as a seventh grader. #nasa @issnationallab @iss #space #stemeducation #spacecamp #iss #huntsvillealabama #launchamerica #stem https://www.instagram.com/p/CHcDEIWjriP/?igshid=rb5zh2exe8bt

Hubble Peers at Cosmic Blue Bauble

NASA - Hubble Space Telescope patch. April 12, 2019

Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all. Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered. However, what makes Messier 3 extra special is its unusually large population of variable stars — stars that fluctuate in brightness over time. New variable stars continue to be discovered in this sparkling stellar nest to this day, but so far we know of 274, the highest number found in any globular cluster by far. At least 170 of these are of a special variety called RR Lyrae variables, which pulse with a period directly related to their intrinsic brightness. If astronomers know how bright a star truly is based on its mass and classification, and they know how bright it appears to be from our viewpoint here on Earth, they can thus work out its distance from us. For this reason, RR Lyrae stars are known as standard candles — objects of known luminosity whose distance and position can be used to help us understand more about vast celestial distances and the scale of the cosmos. Messier 3 also contains a relatively high number of so-called blue stragglers, which are shown quite clearly in this Hubble image. These are blue main sequence stars that appear to be young because they are bluer and more luminous than other stars in the cluster. As all stars in globular clusters are believed to have formed together and thus to be roughly the same age, only a difference in mass can give these stars a different color. A red, old star can appear bluer when it acquires more mass, for instance by stripping it from a nearby star. The extra mass changes it into a bluer star, which makes us think it is younger than it really is. Messier 3 is featured in Hubble’s Messier catalog, which includes some of the most fascinating objects that can be observed from Earth’s Northern Hemisphere.

Venus, Jupiter, and Saturn... These are what I consider my best images. I’ve learned so much this past year, but I have a long way to go. I’m really looking forward to getting Mars later this Summer. #celestrontelescope #celestronuniverse #celestron127slt #backyardastronomy #space #venus #jupiter #saturn #planets https://www.instagram.com/p/CBhhlXVHakg/?igshid=1t6l5o4999j6q

Did you know: NASA's SpaceX Crew-2 is the first NASA Commercial Crew Program mission to fly two international partner astronauts? Both Thomas Pesquet of ESA - European Space Agency and Akihiko Hoshide of JAXA (Japan Aerospace Exploration Agency) will be aboard the Crew Dragon launching April 22 to the International Space Station. #nasa #crewdragon #iss #solarsystemambassador https://www.instagram.com/p/CNmFBvmj2Qk/?igshid=1vvs39ahvj71a
