In 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO), the first mission to be sent by the US to the Moon in over a decade. Once there, the LRO conducted observations that led to some profound discoveries. For instance, in a series of permanently-shaded craters around the Moon’s South Pole-Aitken Basin, the probe confirmed the existence of abundant water ice.
Based on the temperature data obtained by the LRO of the Moon’s southern polar region, the ESA recently released a map of lunar water ice (see animation below) that will be accessible to future missions. This includes the ESA’s Package for Resource Observation and in-Situ Prospecting for Exploration, Commercial exploitation and Transportation (PROSPECT), which will be flown to the Moon by Russia’s Luna-27 lander in 2025.

In the next few decades, NASA, the European Space Agency (ESA), China, and Russia all plan to create outposts on the lunar surface that will allow for a permanent human presence. These proposals seek to leverage advances in additive manufacturing (aka. 3-D printing) with In-Situ Resource Utilization (ISRU) to address the particular challenges of living and working on the Moon.
For the sake of their International Moon Village, the ESA has been experimenting with “lunacrete” – lunar regolith combined with a bonding agent to create a building material. But recently, a team of researchers conducted a study (in cooperation with the ESA) that found that lunacrete works even better if you add a special ingredient that the astronauts make all by themselves – urine!

Despite humanity’s current struggle against the novel coronavirus, and despite it taking up most of our attention, other threats still exist. The very real threat of a possible asteroid strike on Earth in the future is taking a backseat for now, but it’s still there.
Though an asteroid strike seems kind of ephemeral right now, it’s a real threat, and one that—unlike a coronavirus—has the potential to end humanity. Agencies like NASA and the ESA are still working on their plans to protect us from that threat.

For decades, astronomers have been trying to understand why the Milky Way galaxy is warped the way it is. In recent years, astronomers have theorized that it could be our neighbors, the Magellanic Clouds, that are responsible for this phenomenon. According to this theory, these dwarf galaxies pull on the Milky Way’s dark matter, causing oscillations that pull on our galaxy’s supply of hydrogen gas.
However, according to new data from the European Space Agency’s (ESA) star-mapping Gaia Observatory, it is possible that this warp is the result of an ongoing collision with a smaller galaxy. These findings confirm that the warp in our galaxy is not static, but subject to change over time (aka. precession), and that this process is happening faster than anyone would have thought!

The Sun is not exactly placid, though it appears pretty peaceful in the quick glances we can steal with our naked eyes. In reality though, the Sun is a dynamic, chaotic body, spraying out solar wind and radiation and erupting in great sheets of plasma. Living in a technological society next to all that is a challenge.

The CHEOPS (CHaracterising ExOPlanets Satellite) spacecraft just opened the cover on its telescope. The spacecraft was launched on December 18th 2019 and has so far performed flawlessly. In one or two weeks we could get our first images from the instrument.

The ESA has spent the past few years working towards the creation of an international lunar base, something that will serve as a spiritual successor to the International Space Station (ISS). To accomplish this, they have enlisted the help of other space agencies and contractors to develop concepts for space habitats and construction methods as well as ways to provide robotic and logistical support.
Recently, the ESA’s Technology Development Element (TDE) signed on with the French technology developer COMEX to create the TRAILER robotic system. This two-year project will test a new mission architecture where two rovers work in tandem (and with the help of astronauts) for the sake of exploring the lunar surface and building a permanent outpost on the Moon.

The CHEOPS mission is underway. On December 18th, the exoplanet-studying spacecraft launched from Europe’s Spaceport in Kourou, French Guiana aboard a Soyuz-Fregat rocket. Initial signals from CHEOPS show that the launch was a success.

While working at the NASA Johnson Space Center during the 1970s, astrophysicist Donald Kessler predicted that collisions between space debris would become increasingly common as the density of space debris increases in orbit around the Earth – creating a cascading effect. Since 2005, the amount of debris in orbit has followed an exponential growth curve, confirming Kessler’s prediction.
Given that the problem is only going to get worse in the coming years, there is a growing demand for technologies that can remove space debris. Following a competitive process, the ESA recently contracted the Swiss startup ClearSpace Today to create the world’s first debris-removing space mission. This mission, known as ClearSpace-1, is expected to launch by 2025 and will help pave the way for more debris removal missions.

Update: The Analog-1 experiment was a complete success! Astronaut Parmitano completed all the requirements within the specified time frame (one hour). This test is the first step in validating the teleoperation technology.
NASA has been rather up-front about its desire to send astronauts back to the Moon and on to Mars in the coming years. They are joined by multiple space agencies (such as the ESA, Roscosmos, the CNSA and the IRSO) who also wish to conduct their first crewed missions beyond Earth. However, what is often overlooked is the role teleoperated missions will play in the near-future – where humans and robots explore hand-in-hand.
For example, the ESA has embarked upon a series of experiments collectively named Analog-1, where astronauts control robots from space. Yesterday (Nov. 18th), ESA astronaut Luca Parmitano took control of a robot in the Netherlands from the ISS. This experiment and others like it will help prepare astronauts for future missions that will involve the exploration of hazardous or inaccessible off-world environments.
