Perseverance will carry new tech to Mars that represents major technological advances since NASA's last rover — Curiosity — landed on the Red Planet in 2012.

Why it matters: These new experiments and technology demonstrations will fill in gaps in knowledge scientists have about the world and set up future robotic missions in the process.

Details: NASA's Ingenuity helicopter heading to Mars with Perseverance is a technology demonstration designed to autonomously fly through Mars' thin atmosphere as a proof of concept for a full-scale mission in the future.

  • "After receiving commands from Earth relayed through the rover, each test flight is performed without real-time input from Mars Helicopter mission controllers," NASA wrote in a fact sheet.
  • Perseverance will also record sounds from the surface of Mars and during its landing once it arrives about seven months after launch.
  • The scientific tool will allow scientists to listen in as the rover performs its tasks and possibly aid in experiments as Perseverance uses its powerful laser to investigate the composition of Martian rocks.
  • Perseverance's SHERLOC instrument, which is mounted to the rover's robotic arm, will search for organic compounds and possible biosignatures on Mars while also testing out pieces of spacesuit fabric for future human missions.

The big picture: All of these instruments will give scientists a more comprehensive look at Mars than they've had in the past, adding to the data collected by other rovers, landers and orbiters over the decades.

What to watch: Perseverance and all of its technological goodies are expected to leave for Mars Thursday at 7:50am ET from Florida atop a ULA Atlas V rocket.

  • You can watch the launch live via NASA TV starting at 7am ET and follow the Space channel on the Axios app for continuing coverage of the mission.

NASA astronaut Mike Hopkins is slated to head back to the International Space Station next month for his first flight to orbit since 2013.

Why it matters: Hopkins will command the SpaceX Crew Dragon spacecraft that will take him and three other crewmembers — NASA's Shannon Walker and Victor Glover and Japanese astronaut Soichi Noguchi — to the station as part of the capsule's first crewed, non-test flight to orbit.

A new national lockdown will be imposed in the U.K., Prime Minister Boris Johnson announced Saturday, as the number of COVID-19 cases in the country topped 1 million.

Details: Starting Thursday, people in England must stay at home, and bars and restaurants will close, except for takeout and deliveries. All non-essential retail will also be shuttered. Different households will be banned from mixing indoors. International travel, unless for business purposes, will be banned. The new measures will last through at least December 2.

The massive early vote

Early voting in the 2020 election across the U.S. on Saturday had already reached 65.5% of 2016's total turnout, according to state data compiled by the U.S. Elections Project.

Why it matters: The coronavirus pandemic and its resultant social-distancing measures prompted a massive uptick in both mail-in ballots and early voting nationwide, setting up an unprecedented and potentially tumultuous count in the hours and days after the polls close on Nov. 3.
