Spacecraft Discovers Key Molecule In Venus s Atmosphere: related news

Elusive Molecule Found in Venus' Atmosphere

Hydroxyl, an important but difficult-to-detect molecule, has been found in the upper atmosphere of Venus by the Venus Express spacecraft. This is the first time this molecule has been detected on another planet, and even though it is thought to be an "atmospheric cleanser," knowing that it is part of Venus' thick, greenhouse-like atmosphere will help scientists better understand the environment on our next-door planet. “Venus Express has already shown us that Venus is much more Earth-like than once thought. The detection of hydroxyl brings it a step closer,” said one of the Principal Investigators of the VIRTIS experiment on the Venus Express, Giuseppe Piccioni.

Key molecule discovered in Venus's atmosphere

Hydroxyl an important but difficult-to-detect molecule is made up of a hydrogen and oxygen atom each. It has been found in the upper reaches of the Venusian atmosphere some 100 km above the surface by Venus Expresss Visible and Infrared Thermal Imagi ...

Low-Impact Mating System for Docking Spacecraft

A document describes a low-impact mating system suitable for both docking (mating of two free-flying spacecraft) and berthing (in which a robot arm in one spacecraft positions an object for mating with either spacecraft). The low-impact mating system is fully androgynous: it mates with a copy of itself, i.e., all spacecraft and other objects to be mated are to be equipped with identical copies of the system. This aspect of the design helps to minimize the number of unique parts and to standardize and facilitate mating operations. The system includes a closed-loop feedback control subsystem that actively accommodates misalignments between mating spacecraft, thereby attenuating spacecraft dynamics and mitigating the need for precise advance positioning of the spacecraft.

New Details on Venus' Clouds from Venus Express

Mysterious clouds blanket Venus, obscuring our sister planet from view. These clouds billow up between 45 and 70 km above the surface, and in the upper part of the atmosphere, clouds swirl by at a rate of 300 km/h, driven by fierce winds. Composed mainly of sulfuric acid along with chlorine and fluorine, these clouds wouldn’t be friendly to life as we know it, but still, their mysteries beckon us. The science team from the European Space Agency's Venus Express has been imaging the planet's enigmatic atmosphere, and has released new images in several different wavelengths that provide new details on the clouds of Venus.

Floating Cities On Venus

Geoffrey.landis writes "Some of you may have heard me talk about colonizing Venus. Well, for those who haven't, Universe Today is running story about floating cities on Venus. It's a reasonable alternative for space colonies — after all, the atmosphere of Venus (at about 50 km) is the most Earth-like environment in the solar system (other than Earth, of course). '50 km above the surface, Venus has air pressure of approximately 1 bar and temperatures in the 0C-50C range, a quite comfortable environment for humans. Humans wouldn't require pressurized suits when outside, but it wouldn't quite be a shirtsleeves environment. We'd need air to breathe and protection from the sulfuric acid in the atmosphere.'"

7 Minutes of Terror for Phoenix Spacecraft (Video)

Are you ready for the Phoenix spacecraft to land on Mars? At the Jet Propulsion Laboratory, the Entry, Descent and Landing team for Phoenix has been hard at work getting ready, performing simulations to prepare for the real landing, scheduled for May 25, 2008 in a region above Mars' Arctic Circle. Emily Lakdawalla at the Planetary Society has an excellent post about Phoenix's landing elipse, with some great information from JPL's Rob Manning about all the variables the EDL team has to take into account for the landing, such as the spacecraft itself, its entry point, and the properties of the atmosphere. But if you're a more visual-type person, JPL has also put together a couple of videos about the 7 minutes of terror the spacecraft (and the EDL team!) endures from when the vehicle hits the top of the atmosphere, through parachute deploy,

The Yin and Yang of the NeXT Spacecraft

Hard and soft. Dark and bright. High and low. Wide and thin. JAXA and NASA. And that's just one spacecraft. Japan's space agency, JAXA and NASA are teaming up to create a new spacecraft to study the extreme environments of the universe. NeXT, which stands for New exploration X-Ray Telescope is a next generation x-ray astronomy satellite currently under development, with launch scheduled in 2013. While Japan will provide the main spacecraft and several instruments, NASA, and in particular the Goddard Space Flight Center just announced they will be adding a new instrument to the spacecraft, the High-Resolution Soft X-Ray Spectrometer (SXS). While the spacecraft's main instrument will be its Hard X-ray Telescope (HXTs) the addition of SXS is just one of several complementary instruments that provide a "yin and yang" aspect to NeXT's explorat

Warm Coronal Loops May Hold the Key to Hot Solar Atmosphere

Coronal loops, the elegant and bright structures threading through the solar surface and into the solar atmosphere, are key to understanding why the corona is so hot. Yes, it's the Sun, and yes, it's hot, but its atmosphere is too hot. The puzzle as to why the solar corona is hotter than the Sun's photosphere has kept solar physicists busy since the mid-twentieth century, but with the help of modern observatories and advanced theoretical models, we now have a pretty good idea what is causing this. So is the problem solved? Not quite…

Where Is the New Horizons Spacecraft?

Even though New Horizons is the speediest spacecraft ever to travel through our solar system, it still has a long way to go on its voyage to Pluto and the Kuiper Belt. However, New Horizons hit an interplanetary milepost yesterday, June 8, by crossing the orbit of Saturn. At 1.5 billion kilometers or 935 million miles (10.06 astronomical units) distant, that's a mission's worth of miles for most spacecraft. But for New Horizons, it's just another interplanetary milepost on its voyage to the outer reaches of our solar system. As a testament to New Horizons' speed, the spacecraft set a record for the fastest transit to Saturn by any spacecraft, making the trip in two years and four months. Voyager 1, the previous record holder, made the journey in approximately three years and two months.
