Russians Hijack A German Space Telescope

Remember all those sanctions and cancelled projects following Russia’s invasion of Ukraine and how we hoped scientists would rise above it? Well, the Russians will have none of it. They have decided to switch on Germany’s eROSITA space telescope.

Built by the Max Planck Institute and launched in 2019 together with the Russian ART-XC space telescope, the eROSITA was placed in sleep mode back in February shortly after the Russian invasion. Both the German and Russian telescopes are designed to work in tandem to study Dark Energy.

The main scientific goals of eROSITA are

  • to detect the hot intergalactic medium of 50-100 thousand galaxy clusters and groups and hot gas in filaments between clusters to map out the large scale structure in the Universe for the study of cosmic structure evolution,
  • to detect systematically all obscured accreting Black Holes in nearby galaxies and many (up to 3 Million) new, distant active galactic nuclei, and
  • to study in detail the physics of galactic X-ray source populations, like pre-main sequence stars, supernova remnants and X-ray binaries.

In a recent Gizmodo article, Roscosmos chief Dmitry Rogozin stated:

They—the people that made the decision to shut down the telescope—don’t have a moral right to halt this research for humankind just because their pro-fascist views are close to our enemies.

Neither German nor Russian scientists are happy with this political decision. It is likely to have implications for future joint Russian missions.

Whether it is politics or micrometeroids, astronomers have plenty of outside factors messing up well-planned missions. 

International Space Station: Russians Still Busy

Earlier today, NASA announced that an uncrewed Russian cargo ship, Progress 81, arrived at the International Space Station (ISS) without incident. Work continues among the Americans and Russians aboard the ISS regardless of the situation on the ground, which is reassuring.

As NASA administrator Bill Nelson said last month at a Senate Appropriations Committee hearing, there have been a number of “misleading headlines” about the end of Russia’s participation in the ISS program. He also highlighed how US astronauts were able to work together with Soviets during the Cold war. Specifically, he stated:

I see nothing in the very even-keeled professional relationship between the cosmonauts and the astronauts, between mission control in Moscow and Houston, in the training of Russian cosmonauts in America and the training of American astronauts in Moscow and Baikonur…I see nothing that has interrupted that professional relationship, no matter how awful Putin is conducting a war with such disastrous results in Ukraine.

The Latest on Exocomets

We have all heard about exoplanets and exomoons, but what about exocomets? It appears the bodies we can observe outside of our solar system are getting even smaller. In a Scientific American article, “Ukrainian Astronomers Discover ‘Exocomets’ around Another Star,” we learn about Ukrainian astronomers who found five such comets using data from NASA’s Transiting Exoplanet Survey Satellite (TESS).

The comets in question orbit the young star Beta Pictoris, which is about 65 light-years from Earth. This is not the first time comments were detected in this distant solar system’s debris disk. The researchers confirmed those earlier sighting as well. The planet-forming debris surrounding the star presents plenty of opportunities for comet sightings.

Such findings, using information from both the Kepler Space Telescope and TESS, continue to expand our understanding of these objects. Once we focus the James Webb Space Telescope on these little bodies, it should get even more interesting.

Starlink Assists with Ukrainian Battles

SpaceX’s Starlink system, shared with Ukraine last month, is already proving to be a boost to Ukrainian fighters. While the focus of the new system was to keep Ukrainians connected to the Internet, it has also been used by drones attacking Russian military tanks and trucks. The NY Post quotes one Ukrainian source as stating, “If we use a drone with thermal vision at night, the drone must connect through Starlink to the artillery guy and create target acquisition.”

All of this will make the Starlink system within Ukraine a Russian target and Mr. Musk himself persona non grata, not that Mr. Musk really cares. However, he has warned Ukrainians to be cautious when using the system:

Important warning: Starlink is the only non-Russian communications system still working in some parts of Ukraine, so probability of being targeted is high. Please use with caution.

Let’s just hope that all of this doesn’t lead to anti-satellite actions in space. We have enough issues on the ground.

Cosmonauts Arrive at the International Space Station

On Friday, a Soyuz space capsule arrived at the International Space Station (ISS) with three Russian cosmonauts –  Oleg Artemyev, Denis Matveev, and Sergey Korsakov. This will bring the ISS crew to 10. On March 30th, three crew members will return to the surface of the Earth – NASA astronaut Mark Vande Hei and Russian cosmonauts Pyotr Dubrov and Anton Shkaplerov. You can read more about the mission here.

With the ongoing disagreements between the Russian and Western governments regarding Ukraine, it is good to see some normal operations related to the ISS. Let’s hope the science can continue in space while discussions continue back here on Earth to end the ongoing war.

Update: The media was abuzz regarding the blue and yellow outfits of the three astronauts arriving at the station. Was it support for Ukraine or their alma mater? One cosmonaut said there was simply an excess of yellow material. Another space mystery.
