The Opportunity Mars rover’s greatest shots and discoveries

Opportunity’s mission is complete, and the rover that was supposed to last 90 days closes the book on 15 years of exploration. It’s sad, but it’s also a great time to look back on the mission and see some of its greatest hits. Here are 25 images showing where it came from, where it went, […]

Opportunity Mars rover goes to its last rest after extraordinary 14-year mission

Opportunity, one of two rovers sent to Mars in 2004, is officially offline for good, NASA and JPL officials announced today at a special press conference. “I declare the Opportunity mission as complete, and with it the Mars Exploration Rover mission as complete,” said NASA’s Thomas Zurbuchen. The cause of Opportunity’s demise was a planet-scale […]

NASA cubecraft WALL-E and EVE sign off after historic Mars flyby

A NASA mission that sent two tiny spacecraft farther out than any like them before appears to have come to an end: Cubesats MarCO-A and B (nicknamed WALL-E and EVE) are no longer communicating from their positions a million and two million miles from Earth, respectively. The briefcase-sized craft rode shotgun on the Insight Mars […]

Watch Blue Origin’s 10th New Shepard mission launch a science-loaded capsule to space

Blue Origin, the rocket company founded by Amazon’s Jeff Bezos, is about to undertake the 10th launch of its New Shepard launch vehicle, with its capsule chock full of experiments. The launch, which was originally scheduled for a month ago but delayed for various reasons, will take place tomorrow at 6:50 AM Pacific time. New […]

The New Horizons probe buzzes the most distant object ever encountered first thing tomorrow

Four billion miles from Earth, the New Horizons probe that recently sent such lovely pictures of Pluto is drawing near to the most distant object mankind has ever come close to: Ultima Thule, a mysterious rock deep in the Kuiper belt. The historic rendezvous takes place early tomorrow morning. This is an encounter nearly 30 […]

Voyager 2 joins its twin in interstellar space

Voyager 2, the multi-planetary exploratory probe launched in 1977, has finally entered interstellar space, some six years after its twin, Voyager 1, did the same. It’s now about 11 billion miles from Earth, the second-farthest-out human-made object in space. Interstellar space starts where the sun’s “heliosphere” ends — the big ball of radiation and plasma […]

Mars Lander InSight sends the first of many selfies after a successful touchdown

Last night’s 10 minutes of terror as the InSight Mars Lander descended to the Martian surface at 12,300 MPH were a nail-biter for sure, but now the robotic science platform is safe and sound — and has sent pics back to prove it. The first thing it sent was a couple pictures of its surroundings: […]

11 moments from the International Space Station’s first 20 years

It was November 20, 1998, when an unprecedented international coalition of astronomers, engineers and rocket scientists saw years of collaboration come to fruition with the launch of the International Space Station’s first component. Since then, the largest spacecraft ever built has hosted innumerable astronauts, experiments and other craft. Here are a few notable moments in […]

The space pen became the space pen 50 years ago

Everyone knows about the space pen. NASA spent millions on R&D to create the ultimate pen that would work in zero gravity and the result was this incredible machine. Well, no. In fact it was made by a pen manufacturer in 1966 — but it wasn’t until October of 1968 that it went into orbit […]

Mars Rover Curiosity is switching brains so it can fix itself

When you send something to space, it’s good to have redundancy. Sometimes you want to send two whole duplicate spacecraft just in case — as was the case with Voyager — but sometimes it’s good enough to have two of critical components. Mars Rover Curiosity is no exception, and it is now in the process […]
