Throwback Thursday Funpost! A spacewalk in deep space
Only three humans have ever been on a spacewalk in the void between the Earth and Moon.
NASA has a Moon landing plan—sort of
It's a gradual, stepped approach, envisioning human spaceflight, planetary science, and commercial partners all working together.
Some snark (and details!) about NASA's proposed lunar space station
So long, Deep Space Gateway. You've been replaced with the Lunar Orbital Platform-Gateway.
Goodbye, ISS. Hello, private space stations?
The International Space Station may go away in 2025. Will private space stations be ready to fill the gap?
International meetings: Moon initiatives
Interest is rising globally in expanded lunar science, resource exploration and eventually permanent human settlement. Also, the potential for commercial lunar enterprises is being seriously examined.
Let's talk about NASA's latest commercial crew delay
SpaceX and Boeing might not be certified to carry astronauts to the International Space Station until 2019 or 2020.
What changed with space directive #1?
President Trump signed Space Directive #1, formally implementing as policy what Vice President Pence had announced at the first meeting of the National Space Council in October: that NASA will focus its human spaceflight efforts on a return to the Moon, and then onto Mars. What really changed?
What's Up in Solar System Exploration in 2018
Three launches to the Moon and one each to Mercury and Mars; two arrivals at near-Earth asteroids; and an approach to an encounter with a distant Kuiper belt object are highlights we anticipate in 2018.
We choose to go to the Moon and do the other things

SpaceX CEO Elon Musk updates Mars colonization plans
SpaceX CEO Elon Musk presented an updated version of his Mars colonization plans today, during a widely anticipated talk at the 68th International Astronautical Congress in Adelaide, Australia.
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.
