SpaceX Falcon Heavy grounding aerospace investigation - Space News (Apr 29, 2026)

Let's start with the headline that's dominating the conversation in the aerospace world. SpaceX's Falcon Heavy rocket has been temporarily grounded by the Federal Aviation Administration. The mishap happened Sunday morning, April 27th, when the rocket launched from Cape Canaveral carrying ViaSat-3 Flight 3, a high-capacity communications satellite. The first stage booster performed flawlessly and landed right on schedule in the Atlantic. But here's where things went wrong. The upper stage ran into trouble. One of its two engines didn't deliver the thrust needed during a critical burn, and the satellite ended up in the wrong orbit, too low to maintain operations. The satellite will eventually fall back to Earth, though its operators say they're covered by insurance. This is the first significant failure for Falcon Heavy in over eighteen months, and the FAA is now requiring a full investigation before any more flights can launch. SpaceX hasn't announced when they might try again.

On a more successful note, United Launch Alliance had a great night just hours before the Falcon Heavy situation unfolded. Also on April 27th, ULA launched an Atlas V rocket carrying 29 Amazon Leo satellites to low Earth orbit. These broadband internet satellites are part of Amazon's plan to build a global internet constellation to compete with services like Starlink. What's interesting here is the logistics. This was ULA's second Atlas V launch of the month, and they set a new company record for turnaround time between missions at that same launch complex. They managed to go from one launch to the next faster than they ever have before. The 29 satellites brought Amazon's growing constellation closer to critical mass, and this mission tied Atlas V's record for the heaviest payload ever carried.

Now, if you were trying to use GPS or radio communications around April 23rd and 24th, you might have noticed some problems. The Sun decided to send a couple of reminders of its power. Two X-class solar flares erupted from active sunspot region 4419, the first peaking on April 23rd at 9:07 PM Eastern time, and the second hitting on April 24th at 4:13 AM Eastern. These are the most intense category of solar flares. The radiation from these eruptions reached Earth and disturbed the ionosphere, creating temporary radio blackouts across the Pacific, Australia, and East Asia. If you rely on shortwave radio or precise GPS signals, you felt this one. The good news is that the sunspots responsible are now rotating away from Earth's view, so the disruptions should continue easing over the next few days.

Finally, there's some exciting news for Mars exploration. NASA has given the green light to begin implementation of the Rosalind Franklin Support and Augmentation project, a partnership with the European Space Agency. This is the mission that's going to put the first rover on Mars specifically designed to dig beneath the surface looking for signs of ancient life. It's scheduled to launch in late 2028, and SpaceX's Falcon Heavy rocket has been selected to carry it to the Red Planet. NASA isn't just providing the rocket though. They're also contributing the landing system engines, heater units for the rover's systems, and some advanced scientific equipment including a mass spectrometer. This European rover will land at Oxia Planum, a region with strong geological evidence of ancient water. For the first time, we'll have a rover that can search below the Martian surface where microbes might have survived ancient radiation and environmental changes.
