United Launch Alliance’s upcoming Vulcan rocket will parachute its giant engines back to Earth for reuse, lowering launch costs to $100 million per mission.

While some planetary scientists are enthusiastic about Trump’s proposal to send astronauts to the moon before Mars, others are leery about what it could cost or if it will happen.

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

But that’s not as bad as it sounds, because the 2016 discovery could help scientists solve one of the biggest mysteries in theoretical physics — where is all the dark matter? — and could also explain why travelling backwards in time might actually be impossible.

The rise of commercial spaceflight companies such as SpaceX and Bigelow Aerospace sparked the age of space tourism as the ultra-wealthy became able to buy a ticket for a rocket ride into space. Of course, there is a huge limit on tourism if there isn’t a place to stay in one’s intended destination, but that’s about to change in space. Bigelow has announced plans to build two space stations that will float in low-Earth orbit. The company has big plans for these space stations and ideas about who might pay to use them. Essentially, the stations will be like orbiting space hotels where astronauts and possibly even tourists might stay one day.

In a press release this week, Bigelow Aerospace announced that it has created a spin-off venture called Bigelow Space Operations, which will operate and manage two space stations that will serve as hotels. The company expects to launch both hotels in 2021, and it’s beginning to work toward building them this year. Bigelow describes the two space stations as “the largest, most complex structures ever known as stations for human use in space.”

The two stations are currently being referred to as B330-1 and B330-2, and they aren’t the only two that Bigelow Space Operations plans to build. The two space stations are inflatable and will provide shelter for up to six people in low-Earth orbit with about 12,000 cubic feet of living space.

How else will astronauts get a Big Gulp on their way to Mars?

The antimatter of science fiction vastly differs from the real-life antimatter of particle physics. The former powers spaceships or bombs, while the latter is just another particle that physicists study, one that happens to be the mirror image with the opposite charge of the more familiar particles.

Normally, scientists produce antimatter in the lab, where it stays put in an experimental apparatus for further study. But now, researchers are planning on transporting it for the first time from one lab to another in a truck for research. Elizabeth Gibney reports for Nature:

In a project that began last month, researchers will transport antimatter by truck and then use it to study the strange behaviour of rare radioactive nuclei. The work aims to provide a better understanding of fundamental processes inside atomic nuclei and to help astrophysicists to learn about the interiors of neutron stars, which contain the densest form of matter in the Universe.

The experiment was held near the isolated Israeli township of Mitzpe Ramon, whose surroundings resemble the Martian environment in its geology, aridity, appearance and desolation, the ministry said.

The participants were investigating various fields relevant to a future Mars mission, including satellite communications, the psychological affects of isolation, radiation measurements and search ing for life signs in soil.

Participant Guy Ron, a nuclear physics professor from the Hebrew University in Jerusalem, said the project was not only intended to look for new approaches in designing a future mission to the Red Planet, but to increase public interest.

Based on data from NASA’s K2 mission, an international team of scientists has confirmed nearly 100 new exoplanets. This brings the total number of new exoplanets found with the K2 mission up to almost 300.

“We started out analyzing 275 candidates, of which 149 were validated as real exoplanets. In turn, 95 of these planets have proved to be new discoveries,” said U.S. doctoral student Andrew Mayo at the National Space Institute (DTU Space) at the Technical University of Denmark. “This research has been underway since the first K2 data release in 2014.” Mayo is the main author of the work being presented in the Astronomical Journal.

The research was conducted partly as a senior project during his undergraduate studies at Harvard College. It also involved a team of international colleagues from institutions such as NASA, Caltech, UC Berkeley, the University of Copenhagen, and the University of Tokyo. The Kepler spacecraft was launched in 2009 to hunt for exoplanets in a single patch of sky, but in 2013, a mechanical failure crippled the telescope. However, astronomers and engineers devised a way to repurpose and save the space telescope by changing its field of view periodically. This solution paved the way for the follow-up K2 mission, which is still ongoing as the spacecraft searches for exoplanet transits.
