Is Mars habitable? With the right technologies, yes
Making Mars habitable will require us to master the conversion of raw Martian materials into resources we can use to survive. Fortunately, Mars has a wealth of usable materials, making it one of the most human-habitable places in the solar system, other than Earth itself.
NASA, international partners consider solar sail for Deep Space Gateway
A Canadian Space Agency proposal would install a solar sail on the outside of the Deep Space Gateway, a miniature space station in lunar orbit.
Meet two astronaut candidates who can help NASA do science on other worlds
Two of NASA's new astronaut candidates are particularly suited to conduct scientific research on other worlds: Zena Cardman, a geobiologist, and Jessica Watkins, a geologist.
Function over form: NASA's Space Launch System gets a new paint job
Last week, NASA revealed an updated design for the Space Launch System, featuring black-and-white checkerboards streaking down each of the vehicle's solid rocket boosters.
Cubes in Space
Aspiring astrophysicist Julie Seven Sage reports from the launch of student-designed CubeSat payloads at NASA's Wallops Flight Center.
HERA team completes 45-day mission to explore asteroid, from Texas
What's it like spending 45 days confined to a habitat at Johnson Space Center simulating a crewed NASA mission to an asteroid? Tim Evans sends us this report.
Space station partners weigh in on NASA’s Deep Space Gateway plans
In March, NASA officials revealed updated plans for a small space station near the Moon called the Deep Space Gateway. Anatoly Zak reports the plans threw a monkey wrench into years-long planning efforts by NASA’s international partners.
Announcing a New Paper on NASA's Mars Exploration Program
NASA’s robotic Mars Exploration Program is on a troubling path of decline—and decisions must be made now in order to stop it. A new report by the Society explains why.
Orbital ATK discusses Antares rocket's future, confirms new NASA cargo mission
Company officials say they have no plans to retire Antares, which has secured its first mission order under the second round of NASA's commercial cargo flights, known as CRS-2.
The anatomy of a delay: Here's a timeline of twists and turns for NASA's SLS and Orion programs
The Space Launch System and Orion won't fly until 2019, and NASA is sticking with its original plan not to include astronauts for the maiden mission. Here is a timeline of some of the programs' major twists and turns over the years.
Does NASA get its money's worth for Antares-Cygnus flights?
Despite being funded to fill a perceived gap in U.S. launch capabilities, Orbital ATK's Antares rocket has yet to find a customer besides NASA. Did the space agency get its money's worth?
HERA crewmember shares thoughts ahead of simulated 45-day asteroid mission
Tonight, a four-person crew will seal themselves inside a three-story habitat at NASA's Johnson Space Center, kicking off a simulated 45-day mission to an asteroid. One crewmember shares his thoughts before entering.
The first Space Launch System flight will probably be delayed
NASA's new heavy lift rocket is currently scheduled to launch the Orion spacecraft on a test flight next year. But all signs are pointing to a probable delay.
Postcard from the Space Symposium: Planetary Society outreach coordinator finds her place in space
The annual Space Symposium brings together space leaders from around the world to discuss, address and plan for the future of space.
Expedition 50 had a fun and good ISS crew
I believe Expedition 50 had a fun and good ISS crew. I base this declaration solely on the moments they shared on social media. This logic is completely bulletproof and there's no point trying to prove otherwise.
NASA unveiled new plans for getting humans to Mars, and hardly anyone noticed
NASA revealed its most concrete plan yet for sending humans back into deep space, centered around a small lunar space station and a reusable transport ship to carry astronauts to Mars and back.
A repeat of the space shuttle's bold test flight? NASA considers crew aboard first SLS mission
NASA has only flown astronauts aboard a rocket's first flight once, when John Young and Bob Crippen took space shuttle Columbia on the boldest test flight in history. What are the risks of repeating the feat for SLS?
NASA, ISS partners quietly completing design of possible Moon-orbiting space station
Could NASA and its international partners construct a space station in orbit around the Moon? Possible designs are being finalized, but the Trump administration has yet to weigh in on the agency's human spaceflight program.
Everything you need to know about tomorrow's historic SpaceX launch
A SpaceX Falcon 9 rocket blasts off from a former space shuttle launch pad tomorrow morning. Here's a rundown of everything you need to know about the historic event.
Let's talk about this whole Moon vs. Mars thing for human spaceflight
NASA's current human spaceflight goal is Mars, but the Trump administration could change that to the Moon. Is that a good idea? Here's an in-depth look at the differences in science gain, the arguments for and against a potential commercial market, and whether or not the technological and operational challenges required to reach the Moon apply to Mars.
