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.

Trump touts press briefing "ratings" as U.S. coronavirus case surge

President Trump sent about a half-dozen tweets on Sunday touting the high television ratings that his coronavirus press briefings have received, selectively citing a New York Times article that compared them to "The Bachelor" and "Monday Night Football."

Why it matters: The president has been holding daily press briefings in the weeks since the coronavirus pandemic was declared, but news outlets have struggled with how to cover them live — as Trump has repeatedly been found to spread misinformation and contradict public health officials.

World coronavirus updates: Total cases surge to over 700,000

Data: The Center for Systems Science and Engineering at Johns Hopkins, the CDC, and China's Health Ministry. Note: China numbers are for the mainland only and U.S. numbers include repatriated citizens and confirmed plus presumptive cases from the CDC

There are now than more than 700,000 confirmed cases of the coronavirus around the world, according to data from Johns Hopkins. The virus has now killed more than 32,000 people — with Italy alone reporting over 10,000 deaths.

The big picture: Governments around the world have stepped up public health and economic measures to stop the spread of the virus and soften the financial impact. In the U.S., now the site of the largest outbreak in the world, President Trump said Saturday he would issue a "strong" travel advisory for New York, New Jersey and parts of Connecticut.
