Since the Voyager probes passed through the Jupiter system in 1979, scientists have been intrigued and mystified by its moon Europa. Once the images these probes acquired of the moon’s icy surface returned to Earth, scientists began to speculate about the possibility of a subsurface ocean. Since then, the detection of plume activity and other lines of evidence have bolstered this theory and fed speculation that there could be life beneath Europa’s icy surface.
According to new research, another critical piece of evidence of Europa’s watery nature has at least been confirmed. Using a similar technique that confirmed the presence of atmospheric water vapor in Jupiter’s moon Ganymede, Lorenz Roth of the KTH Royal Institute of Technology confirmed that Europa has water vapor in its atmosphere. This discovery could lead to a greater understanding of Europa’s atmosphere and surface environment, informing missions headed there in the near future.

BepiColombo made a quick visit to Venus in August and is on to its next rendezvous. On October 1st it’ll perform a flyby of Mercury, the spacecraft’s eventual destination. This visit is just a little flirtation—one of six—ahead of its eventual orbital link-up with Mercury in late 2025.
The quick visit will yield some scientific results, though, and they’ll be just a taste of what’s ahead in BepiColumbo’s one-year mission to Mercury.

In about a year (Sept. 20th, 2022), the Rosalind Franklin rover will depart for Mars. As the latest mission in the ESA’s and Roscosmos’ ExoMars program, Rosalind Franklin will join the small army of orbiters, landers, and rovers that are working to characterize the Martian atmosphere and environment. A key aspect of the rover’s mission will involve drilling into the Martian soil and rock and obtaining samples from deep beneath the surface.
To prepare for drilling operations on Mars, the ESA, Italian space agency (ASI), and their commercial partners have been conducting tests with a replica – aka. the Ground Test Model (GTM). Recently, the test model completed its first round of sample collection, known as the Mars Terrain Simulation (MTS). The rover drilled into hard stone and extracted samples from 1.7 meters (5.5 feet) beneath the surface in a record-breaking feat.

History has viewed mining as a job that requires a lot of heavy machinery and physical labor. Pulling valuable material out of the ground has been necessary for human progress for thousands of years. That progress has led to an alternative method of getting those resources out of the Earth or other celestial bodies. The new technique relies on a symbiotic life partner that has co-habited with us for millennia – bacteria. A recent experiment conducted by ESA’s Biorock investigation team shows that this process – known as “biomining” – might be the most effective way to collect some materials in space.

In this decade, multiple space agencies and commercial space entities will be taking us back to the Moon. But unlike the Apollo Era, the goal of these programs is not “footprints and flags,” but to establish the necessary infrastructure to keep going back. In particular, NASA, the ESA, Roscosmos, and China are all planning on establishing outposts that will allow for scientific research and a sustained human presence.
The ESA is currently showcasing what its outpost will look like at the 17th annual Architecture Exhibition at the La Biennale di Venezia museum in Venice. It’s known as the International Moon Village, which was designed by the architecture firm Skidmore, Owings & Merrill (SOM) with technical support from the ESA. This same company recently unveiled a prototype of the skeletal metal component that will one day be part of the Village’s lunar habitats.

In November (or early December) of this year, after many excruciating delays, NASA’s James Webb Space Telescope (JWST) will finally launch to space. As the most advanced and complex observatory ever deployed, the James Webb will use its advanced suite of instruments to observe stars, exoplanets, and galaxies in the near and mid-infrared spectrum. In the process, it will address some of the most enduring mysteries about the nature of the Universe.
When the time comes, the James Webb will fly aboard an Ariane 5 rocket from the European Space Agency (ESA) launch facility near the town of Korou, French Guayana. Overnight on August 17th, 2021, the upper stage of that Ariane 5 began making its way in its cargo container from the ArianeGroup facility in Bremen, Germany, to Neustadt port, where it will board a ship bound for the ESA spaceport in French Guiana.

Astronomers have an excellent habit of naming large projects after deserving contributors to their field. From Nancy Grace Roman to Edwin Hubble, some of the biggest missions are named after space exploration pioneers. When ESA and JAXA sat down to figure out a name for their new Mercury probe, they would have come across an important name early in their research – Giuseppe “Bepi” Colombo – the man who helped plan the Mariner 10 Mercury mission.

Two spacecraft made historic flybys of Venus last week, and both sent back sci-fi-type views of the mysterious, cloud-shrouded planet.
The Solar Orbiter and BepiColombo spacecraft both used Venus for gravity assists within 33 hours of each other, capturing unique imagery and data during their encounters.

Material science is still the unsung hero of space exploration. Rockets are flashier, and control systems more precise, but they are useless without materials that withstand the immense temperatures of forces required to get people and things off the planet. Now a team from MT Aerospace, working on a grant from ESA, has developed a new type of material that will be immensely useful in one of the most important parts of any rocket engine – the fuel tanks.

Ever since 1971, when the Mariner 9 probe surveyed the surface of Mars, scientists have theorized that there might be subsurface ice beneath the southern polar ice cap on Mars. In 2004, the ESA’s Mars Express orbiter further confirmed this theory when its Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument detected what looked like water ice at a depth of 3.7 km (2.3 mi) beneath the surface.
These findings were very encouraging since they indicated that there could still be sources of liquid water on Mars where life could survive. Unfortunately, after reviewing the MARSIS data, a team of researchers led from Arizona State University (ASU) has proposed an alternative explanation. As they indicated in a recent study, the radar reflections could be the result of clays, metal-bearing minerals, or saline ice beneath the surface.
