Graphene Flagship Partners University of Cambridge (U.K.) and Université Libre de Bruxelles (ULB, Belgium) paired up with the Mohammed bin Rashid Space Center (MBRSC, United Arab Emirates), and the European Space Agency (ESA) to test graphene on the moon. This joint effort sees the involvement of many international partners, such as Airbus Defense and Space, Khalifa University, Massachusetts Institute of Technology, Technische Universität Dortmund, University of Oslo, and Tohoku University.

The Rashid rover is planned to be launched on December 1, 2022 from Cape Canaveral in Florida and will land on a geologically rich and, as yet, only remotely explored area on the moon's nearside—the side that always faces the Earth. During one lunar day, equivalent to approximately 14 days on Earth, Rashid will move on the lunar surface investigating interesting geological features.

The Rashid rover wheels will be used for repeated exposure of different materials to the lunar surface. As part of this Material Adhesion and abrasion Detection experiment, graphene-based composites on the rover wheels will be used to understand if they can protect spacecraft against the harsh conditions on the moon, and especially against regolith (also known as "lunar dust").

NASA is canceling a planned satellite that was going to intensely monitor greenhouse gases over the Americas because it got too costly and complicated.

But the space agency said it will still be watching human-caused carbon pollution but in different ways.

NASA on Tuesday announced that its GeoCarb mission, which was supposed to be a low-cost satellite to monitor carbon dioxide, methane and how plant life changes over North and South America, was being killed because of cost overruns.

When it was announced six years ago, it was supposed to cost $166 million, but the latest NASA figures show costs would balloon to more than $600 million and it was years late, according to NASA Earth Sciences Director Karen St. Germain.

Unlike other satellites that monitor greenhouse gases from low Earth orbit and get different parts of the globe in a big picture, GeoCarb was supposed to be at a much higher altitude of 22,236 miles (35,786 kilometers) from one fixed place in orbit and focus intently on North and South America. That different and further perspective proved too difficult and costly to get done on budget and on time, St.

This glittering group of stars, shining through the darkness like sparks left behind by a firework, is NGC 2660 in the constellation Vela, best viewed in the southern sky. NGC 2660 is an open cluster, a type of star cluster that can contain anywhere from tens to a few hundreds of stars loosely bound together by gravity.

The stars of open clusters form out of the same region of gas and dust and thus share many characteristics, such as age and chemical composition. Unlike globular clusters—their ancient, denser, and more tightly-packed cousins—open clusters are easier to study since astronomers can more easily distinguish between individual stars. Their stars can be old or young, and they may disperse after a few million years into the spiral or irregular galaxies where they are born.

The spikes surrounding many of the stars in this image are "diffraction spikes," which occur when the glow from bright points of light reflects off of Hubble's secondary mirror support.

On Nov. 29, 2021, NASA's Juno mission completed its 38th close flyby of Jupiter. As the spacecraft sped low over the giant planet's cloud tops, its JunoCam instrument captured this look at two of Jupiter's largest moons.
