It’s Been Exactly One Year Since Opportunity Sent This Final Message Home – on its 5,111th Martian Day

Opportunity’s final message home is not much to look at on its own. If you’re old enough to remember film cameras, it looks like the final exposure on a roll of film, developed but partly missing. It’s a suitable epitaph for Opportunity’s mission.

NASA’s next mission to the surface of Mars is called the 2020 rover (in case you didn’t know already.) It’s planned launch date is July 17th, 2020, and it should land at Jezero Crater on Mars on February 18th 2021. The rover is still under construction at the Jet Propulsion Lab in Pasadena, California.

Engineers are Still Troubleshooting Why Mars InSight’s Mole is Stuck and Won’t Go Any Deeper

NASA’s Mars InSight Lander was always a bit of a tricky endeavour. The stationary lander has one chance to get things right, since it can’t move. While initially the mission went well, and the landing site looked good, the Mole is having trouble penetrating deep enough to fulfill its mission.

We’ve learned a lot about Mars in recent years. Multiple orbiters and hugely-successful rover missions have delivered a cascade of discoveries about our neighbouring planet. But to take the next step in unlocking Mars’ secrets, we need to get Martian samples back to Earth.

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment

In June of 2017, NASA’s Neutron Star Interior Composition Explorer (NICER) was installed aboard the International Space Station (ISS). The purpose of this instrument is to provide high-precision measurements of neutron stars and other super-dense objects that are on the verge of collapsing into black holes. NICER is also be the first instrument designed to test technology that will use pulsars as navigation beacons.

Recently, NASA used data obtained from NICER’s first 22 months of science operations to create an x-ray map of the entire sky. What resulted was a lovely image that looks like a long-exposure image of fire dancers, solar flare activity from hundreds of stars, or even a visualization of the world wide web. But in fact, each bright spot represents an x-ray source while the bright filaments are their paths across the night sky.

The 50th anniversary of You-Know-What is coming up and LEGO is getting in on the celebration. The much-beloved company has released a replica of the Apollo 11 Eagle Lunar Lander. The new lander is part of LEGO’s Creator Expert collection.

LEGO teamed up with NASA on this effort, and the model boasts quite a few realistic touches.

Curiosity has Found the Mother Lode of Clay on the Surface of Mars

Clay is a big deal on Mars because it often forms in contact with water. Find clay, and you’ve usually found evidence of water. And the nature, history, and current water budget on Mars are all important to understanding that planet, and if it ever supported life.

Why do Some Hubble Images Have That Chunk Taken Out of the Corner?

Great question! The answer has to do with Hubble’s history.

It’s easy to forget that the Hubble has been in space since 1990. That’s going on 30 years now. And during that time, it’s been serviced and had its cameras upgraded.

This Strange Feature on Mars was Probably the Result of an Ancient Volcanic Explosion

A strange feature on the surface of Mars has kept scientists guessing about its origin. It’s a surface deposit of a mineral which is more common in the interiors of planets. A new study shows that this interior mineral was probably brought to the surface by an ancient explosive volcano.

NASA’s Long-Term Climate Predictions have Proven to be Very Accurate, Within 1/20th of a Degree Celsius

There are a handful of major science institutions around the world that keep track of the Earth’s temperature. They all clearly show that the world’s temperature has risen in the past few decades. One of those institutions is NASA.
