Mars is about to be invaded by planet Earth — big time. Three countries — the United States, China and the United Arab Emirates — are sending unmanned spacecraft to the red planet in quick succession beginning this week, in the most sweeping effort yet to seek signs of ancient microscopic life while scouting out the place for future astronauts.

Renesas announced the RX72N Group and RX66N Group of 32-bit microcontrollers (MCUs), new additions to the RX Family that combines equipment control and networking function on a single chip. Built around the Renesas proprietary RXv3 CPU core, the RX72N features a maximum operating frequency of 240 megahertz (MHz) and two Ethernet channels, and the RX66N features a maximum operating frequency of 120 MHz and one Ethernet channel.

NASA's InSight lander on Mars has captured the low rumble of marsquakes and a symphony of other otherworldly sounds. Scientists released an audio sampling Tuesday. The sounds had to be enhanced for humans to hear.

Wells Fargo agreed Friday to pay $3 billion to settle criminal and civil investigations into a long-running practice whereby company employees opened millions of unauthorized bank accounts in order to meet unrealistic sales goals.

A NASA spacecraft designed to burrow beneath the surface of Mars landed on the red planet Monday after a six-month, 300 million-mile (482 million-kilometer) journey and a perilous, six-minute descent through the rose-hued atmosphere. Flight controllers at NASA's Jet Propulsion Laboratory in Pasadena, California, leaped out of their seats and erupted in screams, applause and laughter as the news came in.

India's space organization is examining the technical snag behind Monday's aborted launch of a spacecraft intended to land on the far side of the moon and expects to set a new launch date within days. The Chandrayaan-2 mission was called off less than an hour before liftoff by the Indian Space Research Organization when a "technical snag" was observed in the 640-ton, 14-story rocket launcher.

At one hot, faraway world, it's always cloudy with a chance of iron rain. That's the otherworldly forecast from Swiss and other European astronomers who have detected clouds full of iron droplets at a hot Jupiterlike planet 390 light-years away. This mega planet is so hot on the sunny side — 4,350 degrees Fahrenheit (2,400 degrees Celsius) — that iron vaporizes in the atmosphere. The iron likely condenses on the cooler night side of the planet, almost certainly turning into rain.
