The U.S. space agency’s 13th administrator, Jim Bridenstine, asks private American firms to help launch a bold new initiative.

Humans are preparing to leave Earth’s orbit for the first time since 1972 — to the moon and eventually to Mars and beyond. That’s the mandate we’ve been given by President Donald Trump and a supportive bipartisan Congress. This is an exciting time to be leading America’s space program.

Today I’m proud to share a bold response to President Trump’s December 2017 call to action, one that will usher in the next chapter of human exploration. We are calling on American companies to help design and develop human lunar landers, reusable systems for astronauts to land on the moon.

As a lifelong NASA supporter, I am thrilled to be talking once again about landing humans on the moon. But to some, saying we’re returning to the moon implies we’ll be doing the same as we did 50 years ago. I want to be clear — that is not our vision. We are going to the moon with innovative new technologies and systems to explore more locations across the surface than we ever thought possible. This time, when we go to the moon, we will stay.

The ability to diagnose disease is becoming faster and more accurate. Will this lead to greater peace of mind?

You feel a horrible stomachache coming on. Are you imagining it? You didn’t eat anything unusual and you don’t feel sick. What could be causing the pain, and how can you make it go away? Now imagine having a medical device that can quickly read your sweat and tell you whether your symptoms are serious and how to best treat them.

Biopsy results can take seven to 10 days, and even simple STD tests take at least 24 hours. Waiting to get a diagnosis can be incredibly stressful. Now, a growing set of researchers and physicians are developing more accurate, quicker medical diagnostics than ever before, paving the way to a future where we may soon be able to test our symptoms in real time and avoid what we all know as hypochondria.

Indonesia’s income lags behind that of many other nations, but its magnanimity doesn’t.

The leaders of RW 03 Tugu Utara, a community group in North Jakarta known by its address, have spent many nights surrounded by piles of coins and boxes of instant noodles. Sorting cash and securing bags of rice are endless tasks in Indonesia, which sits along the Pacific Rim and is regularly hit by earthquakes and volcanic eruptions.

When tragedy strikes, Indonesia swings into action. Despite its gross domestic product per capita ranking 127th in the world — and the fact that 1 in 10 people there still lived below the poverty line as of 2017 — the country has earned a reputation for giving. In fact, according to the 2018 World Giving Index, which tracks how many people donate money, volunteer their time or help out strangers in need, Indonesia is the most generous country in the world.
