Venus on Earth: German space lab to recreate our neighbor's 1,000C surface conditions




The German Space Agency (DLR) has opened a brand new, state-of-the-art facility that will try to recreate the fiery conditions on the surface of Venus, whose heat and thick atmosphere makes it extremely hard to study.

Researchers have previously had a very difficult time studying Earth’s neighbor. 

The planet’s atmosphere is notoriously thick and it is blanketed in clouds of sulfuric acid droplets. 

It traps the sun’s heat and temperatures can reach as high as 470 Celsius (878 Fahrenheit). 

The volatile surface also sees lightning bursts and hurricane-force winds up to 224mph (360kph).

Previously, scientists were forced to tune their instruments to certain wavelengths of infrared light to peer through the dense, carbon dioxide-rich atmosphere. 

These glimpses beneath the atmosphere, dubbed ‘spectral windows,’ were picked up during the flyby of NASA’s Galileo mission to Jupiter as well as the ESA Venus Express spacecraft.

The new chamber at the Planetary Spectroscopy Laboratory (PSL) in Berlin will stoke temperatures as high as 1,000 Celsius. 

The facility is designed to help researchers heat rocks similar to those found on Venus in a bid to better understand the planet’s minerals.

Now, the new chamber will help scientists validate data collected by telescopes by combining them with measurements made in the lab. Scientists believe the process could help track the interactions between the surface and the atmosphere.

"We can demonstrate that, with an orbital instrument, basalt spectra can be easily discriminated from basaltic andesites, andesites, and rhyolite or granite. 

So we can address the question whether the oldest landforms on Venus called tesserae are indeed comparable to Earth's continents,” Jörn Helbert of PSL who led the development of the new facility, told Astrowatch.

Armenian protesters block traffic, railways & airport as protest leader loses PM bid

Anti-government protesters disrupted traffic in Armenia’s capital, blocking railways and roads leading to Yerevan International Airport, after the parliament voted against opposition leader Nikol Pashinyan’s bid for interim PM.
Protesters managed to block streets connecting downtown Yerevan to residential districts, disrupting transportation in Armenia’s capital, footage from the scene shows. 
Yerevan’s metro system has also been paralyzed as demonstrators sit on the tracks, preventing trains from passing.
Meanwhile, protesters disrupted traffic on a road leading to Yerevan’s Zvartnots International Airport, located just 12km from the center of the city. 
Consequently, some passengers had to go the rest of the way on foot in order to catch their flights, according to Sputnik news agency.
Railway services have also been disrupted all across the country amid the demonstrations, a spokesman for South Caucasus Railways confirmed to Interfax. 
Some other highways, including the one connecting th…

Syria threatens to ‘strike Tel Aviv airport’ unless UNSC acts against Israel’s impunity

Damascus has threatened to exercise its legitimate right for self-defense against Israeli aggression and target Tel Aviv airport in a mirror response, unless the Security Council puts an end to IDF intrusions into Syrian airspace.
Apparently fed up with years of Israeli impunity in the Syrian skies and regular strikes carried out in the vicinity of Damascus International Airport, Syria has threatened to retaliate in explicit terms.
“Isn’t time now for the UN Security Council to stop the Israeli repeated aggressions on the Syrian Arab Republic territories?” Syria’s permanent representative to the UN, Dr. Bashar al-Jaafari wondered Tuesday.

Or is it required to draw the attention of the war-makers in this Council by exercising our legitimate right to defend ourself and respond to the Israeli aggression on Damascus International Civil Airport in the same way on Tel Aviv Airport?
Air strikes against alleged ‘Iranian targets’ in close proximity to Syria’s busiest airport have become a norm for…

Iran showcases massive UNDERGROUND missile factory, with new rockets & warheads galore

As Tehran unveiled its newest weapon, it also shared rare footage of a secretive underground complex where Iranian missiles are being built. 
It has vowed to carry on with its missile program, despite objections from the West.
Iran’s new missile was showcased on Thursday, with top military officials unveiling the weapon and, in an unprecedented move, showing the subterranean factory. 
The location of the facility was not disclosed, for obvious reasons.
The facility was described by the Iranian media as an “underground city” – and its scale appears to be quite impressive. Footage from the scene shows vast corridors, full of various missile parts, including warheads, all at different stages of assembly.
The videos also showed workers at the plant fulfilling tasks, from merely spinning nuts to fine-tuning some tiny electronic devices, thought to be parts of the missiles’ guidance system.
The new missile, called Dezful, is said to be an upgraded version of the Zolfaghar ballistic missile. 
It bo…
