Boeing wants to take lessons learned from the International Space Station (ISS) to meet NASA's ambitious 2024 deadline to get humans back to the moon.

Driving the news: The longtime NASA contractor just finished up construction of a full-scale, ground-based model of its prototype for the space agency's lunar gateway. NASA will now start running the prototype through a series of tests.

  • The model — located in Huntsville, Alabama — includes habitation and airlock modules based on Boeing's work developing the ISS.
  • "We have a lot of cool stuff in there," David Pederson, Boeing's test team lead engineer for the gateway, said during a press briefing last week.
  • The demonstrator includes an exercise area with a window, a galley with working water and science experiment boxes.

Details: NASA hopes to launch a lunar gateway as an orbiting base of operations from which astronauts could launch to the lunar surface.

  • Boeing is confident its gateway concept, if selected, would be ready to launch ahead of a 2024 landing.
  • According to Boeing, the modules are designed to launch separately, with the power and propulsion module heading to lunar orbit in 2022.
  • The habitation module would launch one year later.
  • The modules are designed to snap together with little assembly required.

But, but, but: Boeing isn't the only company working on a lunar gateway concept.

  • Lockheed Martin has finished its demonstrator. Northrop Grumman, Sierra Nevada Corp. and Bigelow Aerospace are still working toward turning their models over to NASA for testing.
  • As of March, the space agency says it plans to incorporate the best elements of the demonstrators into the final product, rather than going with one design.

Be smart: NASA's 2024 deadline is extremely ambitious and will likely take a large influx of funding provided by Congress. However, it's unclear whether the Trump administration has enough support to make that lunar mission a reality.

  • The agency was expected to submit its updated budget proposal in mid-April, but that deadline came and went with no word on how much NASA will need to get the job done.
  • In theory, NASA could still aim for the moon without including a gateway in its plans.

CDC lets child migrant shelters fill to 100% despite COVID concern

The Centers for Disease Control is allowing shelters handling child migrants who cross the U.S.-Mexico border to expand to full capacity, abandoning a requirement that they stay near 50% to inhibit the spread of the coronavirus, Axios has learned.

Why it matters: The fact that the country's premier health advisory agency is permitting a change in COVID-19 protocols indicates the scale of the immigration crisis. A draft memo obtained by Axios conceded "facilities should plan for and expect to have COVID-19 cases."

8 Senate Democrats vote against adding $15 minimum wage to COVID relief

Eight Democratic senators on Friday voted against Sen. Bernie Sanders' amendment to ignore a ruling by the Senate parliamentarian and add a $15 minimum wage provision to the $1.9 trillion COVID relief package.

The state of play: The vote was held open for hours on Friday afternoon — even after every senator had voted — due to a standoff in negotiations over the next amendments that the Senate will take up.

CDC: Easing mask mandates led to higher COVID cases and deaths

Easing mask restrictions and on-site dining have increased COVID-19 cases and deaths, according to a study out Friday from the Centers for Disease Control and Prevention.

Why it matters: The report's findings converge with actions from governors this week easing mask mandates and announcing plans to reopen nonessential businesses like restaurants.
