Contact with Earthlings could even be deadly for Martians — and vice versa. Mars doesn’t have any microorganisms to carry disease, and so if cross contamination between Earth and Mars is controlled, Solomon explains that all infectious disease could be eliminated — meaning there should be no intimate connection between the two groups.

But all mutation isn’t bad. Every new baby on Earth is born with 60 new mutations, a number which Solomon says will jump to the thousands on Mars. By mutating, humans on Mars would gain critical, life-saving benefits to cope with the brutal planet: a different skin tone to protect from radiation, less reliance on oxygen to adapt to the thin atmosphere, denser bones to counteract calcium loss during pregnancy.

Solomon even suggests that we could use CRISPR to more purposefully design these helpful mutations.

Researchers have pinpointed a previously unknown source of volcanoes in the extreme depths of Earth — in the transition zone between the upper and lower mantle.

Until now, we thought we had a handle on the ways in which volcanoes form, welling up from the molten regions in the upper mantle beneath our planet’s crust, but the new discovery takes things much farther down.

In the Bermuda islands, which sit atop an extinct volcanic seamount, geologists have found the first direct evidence that material from the transition zone, between 400 and 650 kilometres (250 and 400 miles) below Earth’s surface, can bubble up and be spewed out of volcanoes.

The discovery will help scientists further understand Jupiter’s interior structure — including atmospheric dynamics — as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy.

“Secularvariation has been on the wish list of planetary scientists for decades,” said Scott Bolton, Juno principal investigator from the Southwest ResearchInstitute in San Antonio. “This discovery could only take place due toJuno’s extremely accurate science instruments and the unique nature of Juno’sorbit, which carries it low over the planet as it travels from pole to pole.”

Characterizing the magnetic field of a planetrequires close-up measurements. Juno scientists compared data from NASA’s pastmissions to Jupiter (Pioneer 10 and 11, Voyager 1 and Ulysses) to a new model ofJupiter’s magnetic field (called JRM09). The new model was based on datacollected during Juno’s first eight science passes of Jupiter using itsmagnetometer, an instrument capable of generating a detailed three-dimensionalmap of the magnetic field.

NASA’s Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant’s secular variation is most likely driven by the planet’s deep atmospheric winds.

The discovery will help scientists further understand Jupiter’s interior structure—including atmospheric dynamics—as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy.

“Secular variation has been on the wish list of planetary scientists for decades,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “This discovery could only take place due to Juno’s extremely accurate science instruments and the unique nature of Juno’s orbit, which carries it low over the planet as it travels from pole to pole.”

Standard snapshots from space don’t quite show Earth in all its glory. There’s so much more to see.

To reveal details impossible to observe with the naked eye, Rice University engineers are building a portable spectrometer that can be mounted on a small satellite, flown on an airplane or a drone or someday even held in the hand.

Bioengineer Tomasz Tkaczyk and his colleagues at Rice’s Brown School of Engineering and Wiess School of Natural Sciences have published the first results from a NASA-funded project to develop a small, sophisticated spectrometer with unusual versatility. Their paper appears in Optics Express.

The Giant Magellan Telescope should be observing the heavens by 2026.

The Expedition 59 crew is exploring space’s long-term impacts on biology and physics today helping astronauts go to the Moon in 2024. #Moon2024

The six residents aboard the International Space Station kicked off the workweek today exploring microgravity’s long-term impacts on biology and physics. The Expedition 59 crew is also ramping up for a fourth spacewalk at the orbital lab this year.

NASA is planning to send men and women to the Moon in 2024 and life science on the station will help flight surgeons keep lunar astronauts healthy. The space physics research will also provide critical insights to engineers designing future spacecraft and habitats for exploration missions.

Still missing? The total cost. And that’s probably by design.

Those who watched the full 51-minute version of Jeff Bezos’ May 9 Blue Moon announcement were treated to a tutorial on the work of Dr. Gerard K. O’Neill. In the 1970s Dr. O’Neill popularized the idea of space colonies that rotate in orbit allowing tens of thousands of inhabitants to live comfortable lives in Earth-like habitats. Bezos even commissioned updated renderings to excite the audience’s imagination.

Bezos articulated, as he has on many occasions that human civilization should and must expand out into the space to live and work in permanent space settlements. Doing so will allow the best planet in the Solar System, the Earth, to become a protected treasure in the vast harshness of space.

He understands that by creating the infrastructure to accelerate economic development in space his vision of space settlement will more rapidly come to fruition. But Bezos is sober about his space colony ambitions. He calls it a multigenerational endeavor. And so it may be.
