They need to make the first Mars colony look like this! đŽ đ.
NetHack, which was first released in 1987, is more sophisticated than might be assumed. It tasks players with descending more than 50 dungeon levels to retrieve a magical amulet, during which they must use hundreds of items and fight monsters while contending with rich interactions between the two. Levels in NetHack are procedurally generated and every game is different, which the Facebook researchers note tests the generalization limits of current state-of-the-art AI.
Facebook researchers believe the game NetHack is well-tailored to training, testing, and evaluating AI models. Today, they released the NetHack Learning Environment, a research tool for benchmarking the robustness and generalization of reinforcement learning agents.
For decades, games have served as benchmarks for AI. But things really kicked into gear in 2013 â the year Google subsidiary DeepMind demonstrated an AI system that could play Pong, Breakout, Space Invaders, Seaquest, Beamrider, Enduro, and Q*bert at superhuman levels. The advancements arenât merely improving game design, according to folks like DeepMind cofounder Demis Hassabis. Rather, theyâre informing the development of systems that might one day diagnose illnesses, predict complicated protein structures, and segment CT scans.
The launch of NASAâs next Mars rover has been delayed to no earlier than July 22 due to a contamination issue with ground support equipment, the space agency said today (June 24).
NASAâs Mars rover Perseverance was scheduled to launch toward the Red Planet on July 20 from a pad at the Cape Canaveral Air Force Station in Florida. But a problem cropped up as engineers worked to encapsulate the rover in the nosecone of its Atlas V rocket, which was built by United Launch Alliance.
It started with a blast.
On June 23, construction company Kiewit Alberici Joint Venture set off explosives 3,650 feet beneath the surface in Lead, South Dakota, to begin creating space for the international Deep Underground Neutrino Experiment, hosted by the Department of Energyâs Fermilab.
The blast is the start of underground excavation activity for the experiment, known as DUNE, and the infrastructure that powers and houses it, called the Long-Baseline Neutrino Facility, or LBNF.

Have you ever wondered what sunsets on other worlds might look like?
Now you can find out, thanks to simulations created by Goddard scientist Geronimo Villanueva.
When sunlight interacts with molecules in a planetâs or moonâs atmosphere, it creates the kaleidoscope of colors you see in these simulations.

In its 10 years observing the Sun, our Solar Dynamics Observatory satellite has gathered over 425 million high-resolution images of our star.
This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sunâs outermost atmospheric layer â the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sunâs 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled âSolar Observer,â was composed by musician Lars Leonhard.
Is the Sun an Oddball Star? A fascinating conversation with Kepler and TESS astronomer Travis Metcalfe, of the Space Science Institute in Boulder, Colo., about how our Sun stacks up against other sunlike stars in the galaxy. We cover the history of our solar system, where the Sun might have been born, and why the only intelligent life we know is around this lonely G-Dwarf star.
The star may be extremely young, but its ring of rock and dust is enormous. The size of just the shadow alone would be hundreds of times the size our entire solar system, according to NASA. Light would take more than a month to travel that distance.
By taking additional pictures using filters, the team was able to create a gorgeous, colored image of the star and its âbat shadow.â
