A team of scientists was awarded a cache of previously unopened Apollo-era Moon rock samples this year to turn back the clock and see exactly what kinds of materials were abundant on the Moon in its early history.

Why it matters: Researchers have long been interested in figuring out exactly what’s been going on in the interior of our Moon, and this new experiment — which is happening about 50 years after the lunar rock sample was collected — could help create a more complete picture of the history of our natural satellite.

Details: The team will bombard samples of volcanic lunar glass collected during the Apollo 15 mission with photons using the Argonne National Laboratory’s Advanced Photon Source.

  • By working backwards and figuring out what minerals are found within the glass, the research team should be able to get a snapshot of what was happening on the Moon millions of years ago.
  • “This is all about how planets evolved really,” Darby Dyer, principal investigator for the experiment, tells Axios.

The backdrop: NASA saved some samples of moon rocks from the Apollo program in the hopes that scientists would be able to gain new insights with technology that was yet to be developed.

  • Eight other teams will also use untouched moon rock samples for experiments selected by NASA.
  • Dyer expects the first results from the experiments to come in March.

The incoming Biden administration will reverse President Trump's last-minute order to lift COVID-19 related travel restrictions, Jen Psaki, the incoming White House press secretary, tweeted.

Why it matters: President Trump ordered entry bans lifted for travelers from the U.K., Ireland, Brazil and much of Europe to go into effect Jan. 26, but the Biden administration will "strengthen public health measures around international travel in order to further mitigate the spread of COVID-19," Jen Psaki said. Biden will be inaugurated on Wednesday, Jan. 20 and Trump will no longer be president by the time the order is set to go into effect.

Dominion Voting Systems on Monday sent a cease and desist letter to My Pillow CEO Mike Lindell over his spread of misinformation related to the 2020 election.

Why it matters: Trump and several of his allies have pushed false conspiracy theories about the company, leading Dominion to take legal action. It's suing pro-Trump lawyer Sidney Powell for defamation and $1.3 billion in damages, and a Dominion employee has sued Trump himself, OANN and Newsmax.
