NASA's little Ingenuity helicopter on Mars will have to wait a bit longer to take to the Martian skies for the first time after a problem was detected during a test last week.

Why it matters: If the eventual flight is successful, this will mark the first time an aircraft has flown on a world other than Earth, opening the door to a new type of planetary exploration.

What's happening: The little helicopter was expected to fly Sunday, but an unexpected reading during a ground test caused mission managers to delay its flight to Wednesday.

  • Now, updates to Ingenuity's software required to fix the problem have delayed its flight again, with NASA saying it plans to set a date next week.
  • The space agency hasn't yet announced the timing for the test, but NASA is planning to air a livestream of the data analysis from the flight.
  • The drone is expected to climb 10 feet into the thin air for about 30 seconds before coming back in for a landing. It will take photos and collect data through the test. If the flight goes well, Ingenuity will fly subsequent tests over the next month or so.

The big picture: NASA hopes that if Ingenuity proves to be successful, the space agency will be able to use drones like it for future missions to Mars and even other objects in the solar system.

  • Spacecraft in orbit give researchers a good view of a huge swath of land, but a drone can help put different regions in context with one another and perform reconnaissance work for rovers and astronauts.

Background: Ingenuity flew to Mars attached to the underbelly of the Perseverance rover, which made it to the planet's surface in February.

  • The helicopter detached from the rover and managed to survive its first Martian night solo on the surface.
  • Ingenuity is also carrying a very small piece of fabric from a wing of the Wright Brothers' aircraft, called the Flyer.

The push to define workers' rights in space

As humanity stretches into orbit and beyond, experts are still grappling with how rights afforded to workers on Earth apply to those living in space.

Why it matters: In order to create businesses and perhaps societies in space — where the biological necessities for sustaining human life, like air and water, aren't readily available — there will need to be fundamental rights agreements to guarantee laborers aren't exploited.

A major storm system was pummeling Northern California and parts of the Pacific Northwest with heavy rains overnight.

The big picture: "Atmospheric river" storms, associated with a record-strong "bomb cyclone" offshore from the Pacific Northwest, have brought flooding and mudslides to parts of California that were razed by recent wildfires and in severe drought. It's also caused widespread power outages in California, Oregon and Washington state.

A series of powerful "atmospheric river" storms are delivering historic amounts of rainfall across parts of drought-stricken California and the Pacific Northwest — triggering widespread power outages and flooding.

Why it matters: The strong atmospheric river, packing large amounts of moisture, is causing Northern California to whiplash from drought to flood.
