NASA is Looking for Ideas on How to Jump-Start a Lunar Economy!

In less than four years, NASA intends to send the first woman and the next man to the Moon as part of Project Artemis. This will be the first crewed mission to the lunar surface since Apollo 17, the last mission of the Apollo Program, in 1972. It’s also the culmination of decades of planning, research, development, and robotic missions that helped pave the way. And all along NASA has been clear what their overall goal is:

“We’re going back to the Moon! And this time, we’re going to stay!”

In addition to sending astronauts back to the lunar surface by 2024, NASA also plans to establish infrastructure by the end of the decade that will allow for a “sustainable lunar exploration” program. To achieve this, NASA and HeroX have launched the NASA Lunar Delivery Challenge, which will award $25,000 in prizes to teams who can design systems capable of handling payloads that will be delivered to the lunar surface.

Based on Kepler Data, There’s a 95% Chance of an Earth-Like Planet Within 20 Light-Years

In the past few decades, the study of exoplanets has grown by leaps and bounds, with 4296 confirmed discoveries in 3,188 systems and an additional 5,634 candidates awaiting confirmation. Because of this, scientists have been able to get a better idea about the number of potentially-habitable planets that could be out there. A popular target is stars like our own, which are known as G-type yellow dwarfs.

Recently, an international team of scientists (led by researchers from the NASA Ames Research Center) combined data from by the now-defunct Kepler Space Telescope and the European Space Agency’s (ESA) Gaia Observatory. What this revealed is that half of the Sun-like stars in our Universe could have rocky, potentially-habitable planets, the closest of which could be in our cosmic backyard!

NASA Announces the Discovery of Water in the Sunlit Parts of the Moon

For decades, astronomers have speculated that there may be water on the Moon. In recent years, this speculation was confirmed one orbiting satellite after another detected water ice around the Moon’s southern polar region. Within this part of the lunar surface, known as the South-Pole Aitken Basin, water ice is able to persist because of the many permanently-shadowed craters that are located there.

But until now, scientists were operating under the assumption that lunar water was only to be found in permanently shadowed craters. But thanks to NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), water has been observed on the sunlit side of the Moon for the first time. This discovery indicates that water may be distributed all across the lunar surface, and not limited to the dark corners.

NASA releases new spooky space-themed posters about extreme places in the Universe

While ghouls and goblins may provide the ghastly delights many of us associate with this time of year, NASA has just released a series of spooky space-themed posters that are more unearthly than any monsters or scary stories told around terrestrial campfires. This year for Halloween, the space agency has released a series of spine-tingling posters called Galaxy of Horrors. The terrifying destinations highlighted within are all based on real locations in the Universe.

ISS Crew Return Safely to Earth

On the evening of Wednesday, Oct. 21^st, the crew of Expedition 63 finally returned to Earth after spending 196 days in space. It all began when NASA astronaut Chris Cassidy (commander) and Russian cosmonauts Ivan Vagner and Anatoly Ivanishin (both flight engineers) departed the International Space Station (ISS) aboard their Soyuz spacecraft at 07:32 PM EDT (04:32 PM PDT) and landed in Kazakhstan by 10:54 PM EDT (07:54 PM PDT).

What Martian Settlers Need to Know About Soil Can Teach us How to Grow Better on Earth

When human beings start living in space for extended periods of time they will need to be as self-sufficient as possible. The same holds true for settlements built on the Moon, on Mars, and other bodies in the Solar System. To avoid being entirely dependent on resupply missions from Earth (which is costly and time-consuming) the inhabitants will need to harvest resources locally – aka. In-Situ Resource Utilization (ISRU).

This means they’ll have to procure their own sources of water, building materials, and grow their own food. While the ISS has allowed for all kinds of experiments involving hydroponics in space, little has been done to see how soil fares in microgravity (or lower gravity). To address this, Morgan Irons – Chief Science Officer of the Virginia-based startup Deep Space Ecology (DSE) – recently sent her Soil Health in Space experiment to the ISS.

This is What Perseverance’s Landing Site Looked Like Billions of Years Ago. See Why it’s Such a Compelling Target?

Today is a milestone in NASA’s Perseverance mission to Mars. At 1:40 pm Pacific time today, the rover will have traveled 235.4 million km (146.3 million miles). That means the spacecraft is halfway to Mars and its rendezvous with Jezero Crater. The spacecraft isn’t traveling in a straight line, and the planets are moving, so it’s not equidistant to both planets.

“Although we’re halfway into the distance we need to travel to Mars, the rover is not halfway between the two worlds,” Kangas explained. “In straight-line distance, Earth is 26.6 million miles [42.7 million kilometers] behind Perseverance and Mars is 17.9 million miles [28.8 million kilometers] in front.”

But today’s still a good time to take another look at Jezero Crater, and why NASA chose it as the mission’s target.

The Crew of the ISS has Found the Source of the Station’s Air Leak

It’s no secret that the International Space Station (ISS) has had a problem with leaks for more than a year. While pressure loss is a perpetual issue, officials noticed an increase last September, which became more serious over the past summer. As of August, the crew began a hard-target search for the source of the leak, eventually narrowing it down to the Zvezda module in the Russian section.

Thanks to an ongoing search over the past two months, the crew has finally pinpointed the leak using a novel detection method. Simply put, they released tea leaves into the Zvezda module and followed them to the source! According to a statement by Roscosmos, the crew of Expedition 63/64 has patched the hole with some heavy-duty tape they had aboard the station. Talk about DIY repairs!

NASA and Seven Countries Sign the Artemis Accords for the Exploration of the Moon. Russia Declined to Participate

It looks like Russia is thumbing its nose at international cooperation on the Moon. They’ve refused to sign the Artemis Accords, which are a set of rules governing Lunar exploration. NASA and seven other countries have signed on already, with more to come.

In four years, NASA plans to return astronauts to the Moon as part of Project Artemis. To ensure the success of this endeavor, as well as the creation of a program of sustainable lunar exploration by the end of the decade, NASA has partnered with multiple entities in the commercial space sector. Recently, they announced that contracts will be awarded to 14 additional companies to develop a range of proposed technologies.

These proposals are part of NASA’s fifth competitive Tipping Point solicitation, one of many private-public partnership programs overseen by NASA’s Space Technology Mission Directorate (STMD). For this latest solicitation, Tipping Point is awarding contracts with a combined value of over $370 million for technology demonstrations that will facilitate future lunar missions and commercial space capabilities.
