According to NASA, the spacecraft launched with enough fuel to keep it running until 2030, but the agency lost contact with MAVEN after it emerged from behind Mars on December 6. Telemetry data showed that all its subsystems had been working normally prior to the loss of signal, but attempts to reestablish contact were unsuccessful.

Engineers at MIT have successfully tested a hybrid propulsion system for small satellites that combines the raw punch of chemical rockets with the long-haul efficiency of electric thrusters – and crucially,

The quiet hours before a rocket launch always carry a sense of hope, especially when a mission aims to answer old questions about a distant world. That feeling is strong as NASA gets ready to send a pair of identical satellites toward Mars. The mission ...

So why is NASA launching fewer telescopes and planetary science missions than it did a quarter-century ago? The answer is complex. It is not necessarily the money. The space agency’s science budget this year is $7.

This Thursday, Blue Origin successfully launched a pair of NASA spacecraft atop a New Glenn rocket from Florida's Cape Canaveral Space Force Station. The two spacecraft will study Mars' magnetic field and how it's impacted by the Sun and solar wind.

A NASA spacecraft headed toward the asteroid belt will fly past Mars on Friday, aiming to get a boost from the planet's gravitational field and save some of the propellant it needs to complete the second half of a six-year voyage.
