Ceres: An ocean world in the asteroid belt

Liquid water, once thought unique to Earth, may be common on icy worlds throughout the solar system

Remnants of an ancient water ocean are buried beneath the icy crust of dwarf planet Ceres — or, at least, lingering pockets of one. That’s the tantalizing find presented August 10 by scientists working on NASA’s Dawn mission. Their research was laid out in a series of papers published in Nature.

By far, Ceres is the largest object in the asteroid belt, which girdles the inner planets between Mars and Jupiter. But unlike its rockier neighbors, Ceres is a giant ice ball. It holds more water than any world in the inner solar except for Earth. That knowledge had long led some astronomers to suspect Ceres may have once had a subsurface ocean, which is part of the reason NASA sent the Dawn spacecraft there.

However, some models predicted that Ceres' ocean would have frozen long ago, forming the world’s thick, icy crust.

Someday, Mars’ moon Phobos will slip past a certain point in its degrading orbit and get ripped apart by tidal forces, forming a ring. This illustration depicts Phobos midway through that process, overlooking the Red Planet.

U.S. Confirms China Has Launched What Could Be Its Version Of The X-37B Spaceplane

The reusable experimental spacecraft was launched into space on a secret mission from Inner Mongolia earlier today.

BY THOMAS NEWDIC



Beijing says it has successfully launched an uncrewed “reusable experimental spacecraft” from the Jiuquan Satellite Launch Center located in the Gobi Desert in northwest China. Space-Track.org, a U.S. government online database of public space launches that the U.S. military's Combined Space Operations Center and the U.S.-Canadian North American Aerospace Defense Command maintain, confirmed that the "PRC TEST SPACECRAFT" successfully made it into space.

The as-yet-unknown space vehicle was delivered into low Earth orbit atop a Long March 2F carrier rocket on September 4, 2020. The launch was the 14th mission for the Long March 2F rocket and was apparently the result of months of preparations at Jiuquan.

Citar
Uranus and Neptune are called ice giants because they are smaller and compositionally different from Jupiter and Saturn, the gas giants. Jupiter and Saturn are composed of mostly hydrogen and helium, with large mantles of metallic hydrogen (which acts like a metal, due to the pressure and temperature within these planets) and only small cores of rock and ice. This is why they are called gas giants: They are mostly gaseous, with very little rock and ice.


Citar
Uranus (left) and Neptune are classified as ice giant planets because their rocky, icy cores are proportionally larger than the amount of gas they contain. The gas giants — Jupiter and Saturn — contain far more gas than rock or ice.

Russia building nuclear-powered space tug
Posted on September 19, 2020

Russia is reviving one of the Soviet-era space concepts – nuclear-powered space transportation – by building a space tug for a trip to the Moon, Venus and Jupiter.




he space tug is part of the Nuklon space complex, a scientist from Russia’s state space corporation Roscosmos told TASS news agency.

The space tug is being assembled by KB Arsenal under the project name Transport and Energy Module (TEM.)

Alexander Bloshenko says the nuclear-powered space tug’s – propelled by electric engines – first flight will be a full-fledged scientific mission that will deliver a research satellite to the Moon and head for Venus.

It will then perform a gravity assist maneuver to head towards Jupiter.

Astronomers spy phosphine on Venus, a potential sign of life
On Earth, the toxic gas is produced by microbial life. Could the same be true on Venus? Now, the debate begins.


Citar
The surface of Venus is a hellscape. However, some layers of its clouds sport surprisingly hospitable temperatures and pressures. And now, researchers have discovered a unique chemical signature that may be indicative of microbial life.
