China’s space program will launch a Mars mission in July, according to its current plans. This will include deploying an orbital probe to study the red planet, and a robotic, remotely-controlled rover for surface exploration. The U.S. has also been planning another robotic rover mission for Mars, and it’s set to take off this summer, too – peak time for an optimal transit from Earth to Mars thanks to their relative orbits around the Sun.

This will be the first rover mission to Mars for China’s space program, and is one of the many ways that it’s aiming to better compete with NASA’s space exploration efforts. NASA has flown four previous Mars rover missions, and its fifth, with an updated rover called ‘Perseverance,’ is set to take place this years with a goal of making a rendezvous with Mars sometime in February 2021.

NASA’s mission also includes an ambitious rock sample return plan, which will include the first powered spacecraft launch from the red planet to bring that back. The U.S. space agency is also sending the first atmospheric aerial vehicle to Mars on this mission, a helicopter drone that will be used for short flights to collect additional data from above the planet’s surface.

The US Space Force has announced that it is looking for a place to establish its new HQ, and is encouraging communities across the US to nominate themselves based on a set of criteria.

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.

Astronomers have known that Sagittarius repeatedly smashes through the Milky Way’s disc, as its orbit around the galaxy’s core tightens as a result of gravitational forces. Previous studies suggested that Sagittarius, a so called dwarf galaxy, had had a profound effect on how stars move in the Milky Way. Some even claim that the 10 000 times more massive Milky Way’s trademark spiral structure might be a result of the at least three known crashes with Sagittarius over the past six billion years.

Mars’ early surface likely resembled a mud stew of water and volcanic-like processes, say researchers.

A large number of mountain cones in Mars’ northern hemisphere are likely the product of ancient mud volcanoes, says a new paper.

At the agency’s Jet Propulsion Laboratory, team members are building the Coronagraph Instrument for the spacecraft and contributing to the mission’s science goals.

NASA is naming its next-generation space telescope currently under development, the Wide Field Infrared Survey Telescope (WFIRST), in honor of Nancy Grace Roman, NASA’s first chief astronomer, who paved the way for space telescopes focused on the broader universe.

Education Saturday with Space Time.

This episode of space time is brought to you by the information flowing through an impossibly complex network of quantum entanglement, that just happens to mutually agree that you and I exist inside it. Oh, and Schrodinger’s cat is in here too.

As a life support engineer at NASA Ames Research Center, it’s Michael Flynn’s job to keep astronauts alive in space, making sure they have the basic necessities like clean water to survive. But launching clean water into space is cost-prohibitive, so for years, Flynn and his team have been working on new ways to recycle waste water into safe, drinking water. SmartPlanet visits Flynn’s lab and looks at how he’s doing it through a process known as “forward osmosis.”

Tomorrow, May 20, watch as the Japan Aerospace Exploration Agency (JAXA) uncrewed HTV spacecraft lifts off from Japan, on a mission to carry cargo to the International Space Station. It’ll deliver more than four tons of supplies, water, spare parts and experiment hardware for the station crew. Live coverage begins at 1 p.m. EDT with liftoff scheduled for 1:31 p.m. EDT.

Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars.

The model shows that vibrations, or oscillations, inside the stars can be directly measured from the gravitational-wave signal alone. This is because neutron stars will become deformed under the influence of tidal forces, causing them to oscillate at characteristic frequencies, and these encode unique information about the star in the gravitational-wave signal.

This makes asteroseismology — the study of stellar oscillations — with gravitational waves from colliding neutron stars a promising new tool to probe the elusive nature of extremely dense nuclear matter.
