On Sept. 25, Meir will co-pilot a Russian Soyuz spacecraft launching from Kazakhstan with Russian cosmonaut Oleg Skripochka. They will be joined by Hazzaa Ali Almansoori, the first astronaut from the United Arab Emirates. Meir, the daughter of a mother from Sweden and an Iraqi-Israeli father, holds Swedish and American citizenship. She will be the first Swedish woman, the fourth Jewish woman and the 15th Jew overall to be part of a space mission.

Amazon billionaire Jeff Bezos today laid out the architecture for missions to the moon aimed at supporting NASA’s goal of landing astronauts on the lunar surface by 2024. The game plan for Bezos’ space venture, Blue Origin, calls for continuing work on the company’s Blue Moon lunar lander and a new breed of hydrogen-fueled rocket engine known as the BE-7.

The main mission was to check out the launch system in preparation for flying people later this year, but Blue Origin said it flew 38 commercial payloads in the crew capsule -- including a 3-D printer and a scientific centrifuge designed for use in zero-gravity.

The asteroid belt is composed of three types of asteroid: C-type (carbonaceous, ~75 percent of all asteroids), S-type (silicate-rich, ~17 percent of asteroids) and M-type (metal-rich), which are roughly 10 percent of the total population. The numbers, in this case, don’t add up to 100 percent because we aren’t sure of the exact ratios. 16 Psyche is an M-type asteroid made of iron-nickel. What makes it unusual is that it’s believed to be the now-exposed core of a protoplanet. It’s also estimated to be worth $10,000 quadrillion dollars, if anybody has a towing hitch handy.

"2019 is the year when the training wheels come off and the world gets to see what CRISPR can really do for the world in the most positive sense," says Fyodor Urnov, a gene-editing scientist at the Altius Institute for Biomedical Sciences in Seattle and the University of California, Berkeley. Here are highlights of the year ahead in CRISPR research, and answers to common questions about the technology.

As we mark fifty years since the Apollo 11 mission landed Americans on the Moon, capturing the imagination of the world, our Nation is again on the verge of a new bold era in science and technology. Breakthroughs in medicine, communications, transportation, physics, engineering, biology, and many other fields, will help tackle the greatest challenges of our time and allow Americans to live safer, healthier, and more economically prosperous lives.

The plan is divided into three objectives: developing and delivering transformational capabilities; reforming the way science and technology is led and managed; and deepening and expanding scientific and technical enterprise. The Air Force will focus on developing and delivering transformational, operational capabilities by restructuring its science and technology portfolio.

Roughly every 100,000 years, there's a supervolcano explosion somewhere in the world, the consequences of which can be fatal. If the volcano below Yellowstone National Park were to erupt, it would result in worldwide hunger and a volcanic winter (the cooling of the lower atmosphere). According to UN estimates reported by The Guardian, an eruption could leave us with just enough food reserves for exactly 74 days.

In the debate over whether human beings should set off to other worlds beyond Earth, one of the most compelling cons is this: Our bodies don’t like it. Few people know this better than Scott Kelly, the NASA astronaut who spent nearly a year on the International Space Station from 2015 to 2016. Like other astronauts, Kelly served as a test subject in the study of space travel’s effects on the human body. Unlike other astronauts, Kelly has an identical twin, Mark, an astronaut himself.

Some may not be impressed by the slight blurriness of the image. But there’s so much more to it than what immediately meets the eye. Two astrophysicists — Sheperd Doeleman, the project leader of the Event Horizon Telescope, and Katie Mack of North Carolina State University, who was not involved with the effort — walked me through a few of the coolest aspects of the image that helped me appreciate just wonderfully mind-blowing it is.
