Missions
In 2029 an asteroid will pass closer than our satellites — and two spacecraft will be waiting
On April 13, 2029, the asteroid Apophis will skim just 32,000 kilometres above Earth, visible to the naked eye for billions of people. It will miss us — but NASA and ESA are sending spacecraft to watch what Earth's gravity does to it, a free experiment in planetary defense.

Missions
A NASA spacecraft is gliding toward a world made largely of metal
Psyche is cruising on a faint blue glow of ion thrust toward an asteroid unlike any we've visited — a body that may be the exposed metal heart of a shattered protoplanet, and a chance to see the kind of core that hides inside Earth.

Missions
Meet the Artemis III crew: a record-holder, a European pilot, and a mission that isn't a landing
NASA has named the four astronauts assigned to Artemis III — Randy Bresnik, Luca Parmitano, Andre Douglas, and Frank Rubio. The roster is heavy on experience and, for the first time on an Artemis crew, includes a European Space Agency astronaut.

Missions
NASA is building a nuclear-powered drone to fly across the dunes of Titan
Dragonfly is unlike any spacecraft ever flown: a car-sized rotorcraft that will hop from site to site across Saturn's giant moon, a world with rivers and lakes of liquid methane and a chemistry that may echo the conditions before life began on Earth.

Missions
NASA's biggest planetary spacecraft is halfway to an ocean it has never seen
Europa Clipper is cruising toward Jupiter's ice-covered moon, where a saltwater ocean larger than all of Earth's may lie beneath the crust. This December it swings past Earth for a gravitational boost — one more step on a six-year road to one of the solar system's best bets for life.

Missions
NASA names the Artemis III crew this week — for a mission that is no longer a Moon landing
On June 9 NASA will introduce the astronauts assigned to Artemis III. The detail worth understanding first: the mission they're training for has quietly changed from humanity's return to the lunar surface into something more modest — and more telling about where the program really stands.

Missions
Four years after we punched an asteroid, a spacecraft is arriving to read the bruise
In 2022, NASA's DART probe slammed into the asteroid moonlet Dimorphos and changed its orbit. We know it worked — but not precisely why. ESA's Hera reaches the scene in November to turn a one-off stunt into a measured, repeatable technique.

Missions
The race to bring Mars home — and why the U.S. might not win it
NASA has already cached the rocks; it just can't agree on how to retrieve them. China, meanwhile, has set a date. The contest to return the first samples from Mars has quietly become a two-horse race with the favorite stumbling.

Missions
An airplane, a robot, and a falling telescope: the strangest rescue NASA has ever attempted
NASA's Swift observatory is sinking toward reentry. The plan to save it involves a robotic spacecraft, a rocket dropped from a jet over the Pacific — and the last flight of a launcher that ends an entire category of spaceflight.

Missions
The largest planetary spacecraft NASA ever built is bound for an ocean world
Europa Clipper, launched in 2024, is cruising toward a 2030 arrival at Jupiter, where it will make nearly 50 flybys of the icy moon Europa to judge whether its hidden ocean could support life.

Missions
Fifteen years on, Juno is still rewriting Jupiter
NASA's Juno spacecraft, now in extended operations, made a close pass of the small moon Thebe in May — the latest in a mission that has overturned much of what we thought we knew about the giant planet.

Missions
Why Mars landings are an unforgiving engineering problem
Mars has just enough atmosphere to destroy a spacecraft and not enough to land one. Entry, descent, and landing compresses every hard problem in spaceflight into about seven autonomous minutes — and it sets a hard ceiling on how much mass we can put on the surface.
