NASA’s Target for Landing the First Artemis Astronauts on the Moon Slips to 2025

NASA has pushed back the timetable for landing astronauts on the moon for the first time in more than a half-century from 2024 to no earlier than 2025.

Blue Origin’s unsuccessful legal challenge to a $2.9 billion lunar lander contract awarded to SpaceX was one of the factors behind the delay in the Artemis moon program, NASA Administrator Bill Nelson said during a Nov. 9 teleconference.

Nelson also pointed to Congress’ previous decisions not to fund the lander program as fully as NASA wanted, plus delays forced by the COVID-19 pandemic and the fact that “the Trump administration target of a 2024 human landing was not grounded in technical feasibility.”

“After having taken a good look under the hood these past six months, it’s clear to me that the agency will need to make serious changes for the long-term success of the program,” he told reporters.

Crew-2 Safely Returns from ISS — without a working toilet

ESA (European Space Agency) astronaut Thomas Pesquet, left, NASA astronauts Megan McArthur and Shane Kimbrough, and Japan Aerospace Exploration Agency (JAXA) astronaut Aki Hoshide, right, are seen inside the SpaceX Crew Dragon Endeavour spacecraft onboard the SpaceX GO Navigator recovery ship shortly after having landed in the Gulf of Mexico off the coast of Pensacola, Florida, Monday, Nov. 8, 2021.

Four astronauts splashed down safely in the Gulf of Mexico aboard their SpaceX Crew Dragon Endeavour capsule, despite one of the parachutes not deploying immediately. Their spectacular return in darkness from the International Space Station capped off the record-setting mission for the SpaceX Crew-2, with the longest spaceflight by a U.S. crewed spacecraft. Their 199 days in orbit surpassed the 168 days set by NASA’s SpaceX Crew-1 mission earlier this year.

Court Turns Down Blue Origin’s Attempt to Prevent SpaceX’s Lander Contract

For months, the commercial space sector has waited for a pivotal case to be resolved. This was none other than the legal action filed by Blue Origin in response to NASA selecting SpaceX to execute the Human Landing System (HLS) contract worth $2.9 billion. This system is a vital piece of the Artemis Program mission architecture, which will be used in the coming years to transport crew and cargo to the lunar surface.

In a recently-announced decision, the U.S. Court of Federal Claims officially shot Blue Origin’s protest down. This puts an end to nearly seven months of legal proceedings and gridlock following SpaceX’s selection back in April. While this means that SpaceX can get back to developing their concept – the Starship HLS – in preparation for the Artemis III missions, it is unclear if that mission will happen on schedule.

We Now Know Exactly Which Crater the Martian Meteorites Came From

Mars is still quite mysterious, despite all we’ve learned about the planet in recent years. We still have a lot to learn about its interior and surface evolution and how changes affected the planet’s history and habitability. Fortunately, an impact on the red planet sent clues to Earth in the form of meteorites.

The geological information contained in these meteorites would be even more valuable if we knew exactly where they came from. A team of researchers say they’ve figured it out.

Astronomers Measure the Atmosphere on a Planet Hundreds of Light-Years Away

The field of extrasolar planet research has advanced by leaps and bounds over the past fifteen years. To date, astronomers have relied on space-based and ground-based telescopes to confirm the existence of 4,566 exoplanets in 3,385 systems, with another 7,913 candidates awaiting confirmation. More importantly, in the past few years, the focus of exoplanet studies has slowly shifted from the process of discovery towards characterization.

In particular, astronomers are making great strides when it comes to the characterization of exoplanet atmospheres. Using the Gemini South Telescope (GST) in Chile, an international team led by Arizona State University (ASU) was able to characterize the atmosphere of a “hot Jupiter” located 340 light-years away. This makes them the first team to directly measure the chemical composition of a distant exoplanet’s atmosphere, a significant milestone in the hunt for habitable planets beyond our Solar System.

Finally! Here’s the Video of Webb’s Unboxing

It’s been a long time coming. Finally, after years of delays and billions of dollars in budget overruns, the James Webb Space Telescope (JWST) is ready to fly. To celebrate the occasion, ESA released a video showing the “unboxing” of one of the most highly advanced technical achievements in human history. It is truly as impressive as it sounds.

Juno Peers Beneath Jupiter’s Clouds to Reveal its Complex Atmosphere

Many papers are usually released at once for big space exploration missions. Usually, that happens when an entire batch of data has been analyzed. The most recent set of papers is from Juno’s explorations of Jupiter’s atmosphere. With this data dump, scientists now have the first 3D map of the atmosphere of the solar system’s largest planet.

Will Water Bears be the First Interstellar Astronauts?

In just a few years, astronauts will walk on the surface of the Moon for the first time since the Apollo Era. In addition to the Artemis Program, NASA’s fabled return to the Moon, there are also a number of planned missions involving the European Space Agency (ESA), JAXA, China, and Russia. By the 2030s, NASA and China hope to send crewed missions to Mars, which will culminate in the creation of a permanent base on the surface.

When it comes to interstellar missions, however, there are no plans for crewed missions on the table. While there are proposals for sending robotic missions, sending astronauts to nearby stars and exoplanets simply isn’t feasible yet. However, according to new research led by the University of California, interstellar missions could be conducted in the near future that would have tardigrades (aka. “Water Bears”) as their crew.

Experiment Finds no Sign of Sterile Neutrinos

We don’t know what dark matter is. We do know the characteristics of dark matter, and much of how it behaves, so we know what physical properties dark matter must have, but no known matter has all the necessary characteristics of dark matter. So we’re stumped.
