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!

On February 10th, 2020, the ESA’s Solar Orbiter (SolO) launched and began making its way towards our Sun. This mission will spend the next seven years investigating the Sun’s uncharted polar regions to learn more about how the Sun works. This information is expected to reveal things that will help astronomers better predict changes in solar activity and “space weather”.
Last week (on Thursday, Feb. 13th), after a challenging post-launch period, the first solar measurements obtained by the SolO mission reached its international science teams back on Earth. This receipt of this data confirmed that the orbiter’s instrument boom deployed successfully shortly after launch and that its magnetometer (a crucial instrument for this mission) is in fine working order.

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 spacecraft is taking the first tentative steps in its mission. Back on January 29th, the spacecraft opened the cover on its lens. Now, we have the first images from CHEOPS.

In the coming years, a number of will be sent to space for the purpose of answering some of the enduring questions about the cosmos. One of the most pressing is the effect that solar activity and “space weather” events have on planet Earth. By being able to better-predict these, scientists will be able to create better early-warning systems that could prevent damage to Earth’s electrical infrastructure.
This is the purpose of the Solar Orbiter (SolO), an ESA-led mission with strong participation by NASA that launched this morning (Monday, Feb. 10th) from Cape Canaveral, Florida. This is the first “medium-class” mission implemented as part of the ESA’s Cosmic Vision 2015-25 program and will spend the next five years investigating the Sun’s uncharted polar regions to learn more about how the Sun works.

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.

Put “James Webb Telescope launch” into your search engine and you’ll be flooded with links, some reaching back to the ‘scope’s first proposed launch date in 2010. The delayed launch of the space telescope is a running theme in the space community, even though we all know it’s going to be worth the wait. So nobody will be surprised by this latest development in the story of the world’s most anticipated telescope.

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.
