Curiosity has Finally Sampled a Clay-Rich Region on Mars

It’s hard to believe that MSL Curiosity has been on Mars for almost seven years. But it has, and during that time, the rover has explored Gale Crater and Mt. Sharp, the central peak inside the crater. And while it has used its drill multiple times to take rock samples, this is the first sample it’s gathered from the so-called ‘clay unit.’

Metal Asteroid Psyche Might Have Had Volcanoes of Molten Iron

Imagine a time in the Solar System’s past where the asteroids were not solid rock, but blobs of molten iron. It sounds strange, but that may have been the case. And in the right conditions, some of those asteroids would have sprouted volcanoes. One of those asteroids, Psyche, is the destination for a NASA mission.

Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars

Members of the NASA Mars Helicopter team inspect the flight model (the actual vehicle going to the Red Planet), inside the Space Simulator, a 25-foot-wide (7.62-meter-wide) vacuum chamber at NASA's Jet Propulsion Laboratory in Pasadena, California, on Feb. 1, 2019. Image Credit: NASA/JPL-Caltech

We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission.

The Mars Helicopter is pretty small, less than 1.8 kg (4 lb). It’s made of lightweight carbon fiber, and other materials like aluminum, silicon, and foil. The version being tested is the actual vehicle that will make the trip to Mars.

Jupiter or Earth? Which One’s Which, and Why Do They Look so Similar?

Though Jupiter and Earth are wildly differing places, some things are the same on both worlds. Image Credit: NASA

Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.

Earth: a tiny rocky world, almost too close to the Sun, where life rises and falls, punctuated repeatedly by extinctions. Compared to Jupiter, it’s a gum-drop world: Jupiter is 317.8 times the mass of Earth. And Earth is named after a goddess in German paganism, or so we think.

“Out of all the complexity flows beauty…”

Norman Kuring, NASA’s Goddard Space Flight Center.

Now You Can See MU69 in Thrilling 3D

Got your 3D glasses handy? Then prepare for the most realistic views of Ultima Thule yet! Yes, it seems that every few weeks, there’s a new image of the Kuiper Belt Object (KBO) that promises the same thing. But whereas all the previous contenders were higher-resolution images that allowed for a more discernible level of detail, these images are the closest we will get to seeing the real thing up close!

A few hours ago, the SpaceX Crew Dragon splashed down in the Atlantic Ocean, about 200 miles off the coast of Florida. The splashdown is the last act in what has been a successful first flight for the Crew Dragon. The flight, called Demo-1, was launched on March 2nd and spent five days at the International Space Station (ISS).

After more than 10 years of hard work, NASA has reached another milestone. We’re accustomed to NASA reaching milestones, but this one’s a little different. This one’s all about a type of photography that captures images of the flow of fluids.
