NASA’s New Budget for Artemis? $28 Billion

It’s no exaggeration to say that NASA’s plans to return astronauts to the Moon has faced its share of challenges. From its inception, Project Artemis has set some ambitious goals, up to and including placing “the first woman and next man” on the Moon by 2024. Aside from all the technical challenges that this entails, there’s also the question of budgets. As the Apollo Era taught us, reaching the moon in a few years doesn’t come cheap!

Funding is an especially sticky issue right now because of the fact that we’re in an election year and NASA may be dealing with a new administration come Jan of 2021. In response, NASA announced a budget last week (Mon. Sept 21st) that put a price tag on returning astronauts to the Moon. According to NASA, it will cost taxpayers $28 billion between 2021 and 2025 to make sure Project Artemis’ meets its deadline of 2024.

NASA Releases a New Poster for the Europa Clipper Mission

In this decade and the next, some very impressive missions will take place. For instance, NASA will send its robotic Europa Clipper orbiter investigate Jupiter’s icy moon Europa for the first time. The orbiter will launch sometime in the middle of the decade (likely 2024) and arrive in the Jovian sytem in the 2030s to look for possible signs of life.

In preparation for this momentous event, NASA recently released a stunning new mission poster. As you can see, the poster features the orbiter looking down on Europa’s icy surface with Jupiter hanging in the background. The orbiter itself is in shadow so as to draw attention to the landscape beneath it.

Astronauts are Getting a New Toilet Next Week

When astronauts have to go, NASA wants them to boldly go.

A new space toilet is heading to the International Space Station, with official name “Universal Waste Management System” (UWMS). (If it’s NASA, there has to be an acronym). The new toilet is smaller than the current toilets aboard the station, is more user-friendly, and includes 3-D printed titanium parts.

Perseverance Will be Scanning Inside Rocks for Fossils on Mars

On February 18th, 2021, NASA’s Perseverance rover will reach Mars, make a harrowing descent through the planet’s atmosphere, and put down in the Jezero Crater. Like it’s sister-rover, Curiosity, this robotic explorer will explore a region that once supported flowing water and poke around with an advanced suite of scientific instruments for signs of microscopic life that may have existed there billions of years ago.

This is no small feat, which is why the rover will be bringing along its Planetary Instrument for X-ray Lithochemistry (PIXL). This precision instrument is located at the end of its 2-meter (7 foot) long arm and is powered by artificial intelligence (AI). The PIXL will play a pivotal role in Perseverance‘s mission, using a coring drill to obtain samples that will be cached on the surface that will be returned to Earth by a future mission.

The Surface of Mars Might Have Gotten an Acid Bath, Obscuring Evidence of Past Life

People have been speculating about the possibility of life on Mars for centuries. But it’s only since the 1970s and the Viking 1 and 2 missions that we have been able to search for it. After many decades, evidence has mounted that Mars may have once supported life (like the existence of flowing water and organic molecules), but evidence of present-day life has remained elusive.

Unfortunately, according to a recent study by an international team of scientists led by the Spanish Astrobiology Center (CSIC-INTA), it’s possible that the surface of Mars was bathed in acid and alkaline fluids that destroyed all evidence of past life. These findings could have serious implications for upcoming missions to Mars, which includes NASA’s Perseverance and the ESA’s Rosalind Franklin rover.

Artemis Missions Should Bring Ice Home From the Moon Too

During the Apollo Era, astronauts conducted vital science operations on the Moon, which included bringing samples of lunar rocks back to Earth for study. Thanks to the examination of these rocks, scientists were able to learn a great deal about the formation and evolution of the Moon and even found evidence of lunar water. In the coming years, when NASA sends astronauts back as part of Project Artemis, more samples will be returned.

Recently, NASA put out the call for science white papers to help them design a framework for the kind of science operations the Artemis astronauts will conduct. According to one proposal, the Artemis astronauts should not only bring back samples of lunar regolith or rocks but lunar ice as well. By examining them here on Earth, scientists may finally be able to resolve the mystery of where the Moon’s water came from.

NASA Will Pay You to Retrieve Regolith and Rocks from the Moon

As part of Project Artemis, NASA intends to send the first woman and the next man to the Moon by 2024, in what will be the first crewed mission to the lunar since the Apollo Era. By the end of the decade, NASA also hopes to have all the infrastructure in place to create a program for “sustainable lunar exploration,” which will include the Lunar Gateway (a habitat in orbit) and the Artemis Base Camp (a habitat on the surface).

Part of this commitment entails the recovery and use of resources that are harvested locally, including regolith to create building materials and ice to create everything from drinking water to rocket fuel. To this end, NASA has asked its commercial partners to collect samples of lunar soil or rocks as part of a proof-of-concept demonstration of how they will scout and harvest natural resources and conduct commercial operations on the Moon.

An Update on the Damage to the Arecibo Observatory

On Aug. 10th, a little over a month ago, the iconic Arecibo Observatory suffered serious damage when an auxiliary cable broke and struck the reflector dish. This cable struck the observatory’s Gregorian Dome on its way down and twisted an access platform before landing on the reflecting dish itself. The impact created a gash over 30 meters (100 feet) in length and forced the observatory to shut down until repairs could be made.

Since then, teams have been busy working to stabilize the structure and determine the cause. These teams are made up of technicians from the observatory and the University of Central Florida (UCF), which manages the facility for the National Science Foundation (NSF). For the past few weeks, they have been meeting with experts from various fields and laying the groundwork for an investigation and a rigorous repair schedule.

Image-processor extraordinaire Kevin Gill has reached back in time to give us a new image of Neptune and its moon Triton.

When NASA’s Voyager 2 spacecraft flew past Neptune and Triton in August 1989, its cameras were very busy. Kevin has taken separate color-filtered images from that visit and calibrated and combined them to give us a new, almost haunting look at the planet and its largest moon.

James Webb is Working Perfectly! On the Ground. Next Trick: Doing it From Space

When it launches next year, the James Webb Space Telescope (JWST) will be the largest, most complex, and most sophisticated observatory ever sent into space. Because of this, the mission has been delayed multiple times as ground crews were forced to put the telescope through a lengthy series of additional tests. All of these are to make sure that the JWST will survive and function in the vacuum and extreme temperature environment of space.

Recently, the testing teams conducted the critical “Ground Segment Test,” where the fully-assembled observatory was powered up and to see how it would respond to commands in space. These commands were issued from its Mission Operations Center at the Space Telescope Science Institute (STScI) in Baltimore. Having passed this latest milestone, the JWST is now on track for its scheduled launch next year in October.
