As science and technology advance, we’re asking our space missions to deliver more and more results. NASA’s MSL Curiosity and Perseverance rovers illustrate this fact. Perseverance is an exceptionally exquisite assemblage of technologies. These cutting-edge rovers need a lot of power to fulfill their tasks, and that means bulky and expensive power sources.

Centuries after Chinese and Japanese astronomers spotted a bright light in their skies, astronomers have pinned it to a stellar collision that unleashed a rare supernova 850 years ago.
With diminishing ice one of the biggest casualties of our warming world, it’s imperative that accurate measurements continue to be made for scientific research and climate policy, as well as for practical applications such as ship routing. To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.
As long as humanity has looked up at the stars we have dreamed of discovering extraterrestrial life. Astrobiologists attempt to do just this searching for telltale signs of life, potentially habitable worlds, and the answer to the question of how life arose on Earth.

Not so long ago, astronomers thought only a few dozen moons orbited the planets of our solar system. Today, the total count tops 170!
While the Earth absorbs a lot of energy from the Sun, a lot of it is reflected back into space. The sunlight reflected from Earth is called Earthshine. We can see it on the dark portion of the Moon during a crescent Moon. The Farmer’s Almanac said it used to be called “the new Moon in the old Moon’s arms.”
