A handful of spacecraft have used ion engines to reach their destinations, but none have been as powerful as the engines on the BepiColombo spacecraft. BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA.) It was launched on October 20, 2018, and has gone through weeks of in-flight commissioning. On Sunday it turned on its powerful ion thrusters for the first time.
“We put our trust in the thrusters and they have not let us down.” – Günther Hasinger, ESA Director of Science.
BepiColombo is a three-part spacecraft. It has two orbiters, the Mercury Planet Orbiter (MPO) built by the ESA, and the Mercury Magnetospheric Orbiter (MMO) built by JAXA. The third part is the Mercury Transfer Module (MTM), built by ESA. The MTM is the propulsion part of the spacecraft and contains the spacecraft’s four ion engines.

Welcome to another edition of Constellation Friday! Today, in honor of the late and great Tammy Plotner, we take a look at the dragon itself – the Draco constellation. Enjoy!
In the 2nd century CE, Greek-Egyptian astronomer Claudius Ptolemaeus (aka. Ptolemy) compiled a list of all the then-known 48 constellations. This treatise, known as the Almagest, would be used by medieval European and Islamic scholars for over a thousand years to come, effectively becoming astrological and astronomical canon until the early Modern Age.
One of the constellations included in this treatise was Draco, which is located in the northern hemisphere and contains the north pole of the ecliptic. Today, it is one of the 88 modern constellations recognized by the International Astronomical Union (IAU) and is bordered by the constellations of Bootes, Camelopardalis, Cepheus, Cygnus, Hercules, Lyra, Ursa Minor, and Ursa Major.

Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars. The lander is still having its systems tested, and isn’t quite ready to get to work. It’ll use its arm to deploy its science instruments, including a drill that will penetrate up to 5 meters (16 ft.) deep into the Martian surface.

Imagine yourself in a boat on a great ocean, the water stretching to the distant horizon, with the faintest hints of land just beyond that. It’s morning, just before dawn, and a dense fog has settled along the coast. As the chill grips you on your early watch, you catch out of the corner of your eye a lighthouse, feebly flickering through the fog.
And – yes – there! Another lighthouse, closer, its light a little stronger. As you scan the horizon more lighthouses signal the dangers of the distant coast.

The rate at which Greenland is losing its ice is accelerating. This unsurprising conclusion comes from a new study based on 25 years of satellite data from the European Space Agency. The new study was published in Earth and Planetary Science Letters.

It’s a never-ending quest for observers, lovers of the night sky and astrophotographers. Where to go to get away from encroaching light pollution, and find truly dark skies?
Most of us think of distant sites such as Death Valley, the Kalahari Desert or the Canary Islands when it comes to dark skies. And while it’s true that many observers are now traveling farther and farther away from home in search of truly dark skies, that trip need not be as far as you think.
We had the opportunity to visit one such often overlooked dark sky gem: the state of Nebraska. From fossils to aeronautics and astronomy, there’s lots of science to explore in the Cornhusker State. Though the state has a rich science heritage, and an active amatuer astronomy community, Nebraska is an often overlooked dark sky haven. But science tourism is also becoming increasingly popular, and Nebraska has lots to offer.

Our newest planet-hunting telescope is up and running at the ESO’s Paranal Observatory in the Atacama Desert in Chile. SPECULOOS, which stands for Planets EClipsing ULtra-cOOl Stars, is actually four 1-meter telescopes working together. The first images from the ‘scopes are in, and though it hasn’t found any other Earths yet, the images are still impressive.

It’s been a busy time for Elon Musk and SpaceX, lately. Earlier this week, the company launched 64 satellites (and a art project known as the Orbital Reflector) in what was the largest rideshare mission in history. The mission was also historic because it involved a booster making its third successful landing. And this was after Musk released more details about his proposed BFR, henceforth known as the “Starship”
And earlier today (Wednesday Dec. 5th), SpaceX launched its sixteenth Commercial Resupply Services mission (CRS-16) to the International Space Station (ISS). While the deployment of the Dragon spacecraft was successful, the first stage booster did not make it back to the landing pad. After suffering from an apparent malfunction in one of its grid fins, the booster fell into the sea – but remained intact and will be retrieved.

The Large Hadron Collider (LHC) is getting a big boost to its performance. Unfortunately, for fans of ground-breaking physics, the whole thing has to be shut down for two years while the work is done. But once it’s back up and running, its enhanced capabilities will make it even more powerful.
