We were able to go to Venus with today’s technology, scientists say

We were able to go to Venus in the future, the technology that we have today in favour of a NASA scientific advisory group, and the members of the group would be interested in a mission on the ground as soon as possible.

The representatives of the Venus Exploration Analysis Group (VEXAG) made a presentation to NASA’s planetary-science advisory committee, on Sept. 24, it is recommended that the agency’s priority is on a mission to Venus, the second closest planet to the sun.

Mars is a popular destination for many of NASA missions, both because of the possibility of life on the planet, and because the agency could send astronauts there as soon as the 2030s. That said, the us does have a separate call for proposals and to send missions to other solar system sites. With the exception of the close proximity of Venus have not yet been visited by a special NASA spacecraft 25 years old, while the scientists will then be sent to various mission proposals to the agency.

“The Mars program has been” the water is monitored and kept on the look out for any signs of life, but that Mars had liquid water on its surface for several hundred million years ago, [over] three million years ago,” said Dyar, who was the VEXAG presentation, and is the chair of astronomy at Mount Holyoke College in western Massachusetts, in an e-mail to: Space.com.

“In addition, the Mars program has had a long and united around one goal,” Dyar added, “that is, to bring the samples back from Mars. NASA Headquarters is to support the purpose of the plan, as of now. So, my feeling is that, although many of the outstanding scientific questions about Mars to stay, they are second-order compared to the dire state of the state of knowledge about Venus.”

Thus, VEXAG hopes that NASA’s current call for a smaller Discovery missions will continue to bear fruit. The announcement of opportunity, which closed on July 1, with at least three of the Venus and suggestions. Step-1 selections are to be announced in around January, 2020.

The Venus of the proposals DAVINCI (the Deep Atmosphere of Venus, Study of the Noble gases, Chemistry, and Imaging) for the measurement of the chemical composition of Venus during the descent; VERITAS and Venus Emission, Radio Science, InSAR, Topography, and Spectroscopy) orbiter, to explore the surface of Venus at high resolution, and Hyperspectral Observers for Venus Exploration, (REGISTRAR), in order to investigate Venus’ clouds, chemistry, and dynamics of the area, to gain a better understanding of the environment.

The urgent demand for the Venus community is going to have to find out how similar the planet, with the Earth in the planet’s early history. Venus’ size is similar to that of Earth, and its distance from the sun, the planet in the “habitable zone” — the location at which liquid water can exist on the surface, and when the sun was younger and dimmer. Even though Venus is now in a raging inferno, the story of the life of billions of years ago, it would have been more optimistic.

Venus, the scientists want to know if (as some conjecture) that the planet’s liquid water, for 3 billion years from now, what kind of surface geology, rock types, and the nature of its dormant plate tectonics (which may be the key to the preservation of life, and similar to Venus would be able to be a rocky exo-planets very close to their parent stars.

Technical progress

The temperature of the surface of Venus to melt lead, under normal circumstances, and it would cook for a date at times. Is very guarded by Soviet Venera spacecraft made it to the area in the 1970’s and 1980’s, generally lasting anywhere from a few minutes up to about an hour. But with the advances in technology, and the VEXAG group, said, ” it is possible for a reasonable price is on a mission to survive longer in today’s.

VEXAG is the 15th meeting held in 2017, if, for example, noted in NASA’s High Temperature Technology, HOTTech) program, which aims to create components used in environments with approximately 900 degrees Fahrenheit (500 degrees Celsius) or higher. There is a call for proposals, which will be referred to in that amount of time (in 2017) funded research into the technology of solar cells, energy, and electronics, which can be very sensitive to changes in temperature and battery life. The individual projects are expected to complete their current phase of funding between 2018 and 2020, so that the results are still under analysis in some cases.

Other technologies are close to maturity, including NASA’s heat Shield for Extreme Entry Environment Technology (HEEET) project, which is designed for use in environments including those of Venus. It includes a high-density all-carbon layer by the input interface, and a lower density of the insulating layer, in order to protect the delicate parts of the spacecraft. HEEET was testedat NASA’s Ames Research Center, and is included on the technology readiness level (TRL) of 6. (As a component of TRL 7 if it is to be tested in space, and the MUSIC of 8 of the following tests on the ground and in space.)

A team from NASA’s Glenn Research Center is working on a high-temperature of the electronics is designed to Venusian temperatures. It is based on a silicon-carbide power semiconductors, which can reach up to 4000 hours of on the surface. In 2016, the engineers tested a few of the tracks in the Glenn Extreme Environments Rig (GEER), which is designed to simulate conditions on Venus for more than 22 days. (The test was made at that time to the schedule of the reasons, according to NASA; similar to oscillator circuits, and have worked for thousands of hours.)

VEXAG is the latest technology road-map (to be released in conjunction with a technology plan indicate that the community would be able to respond to a variety of a variety of NASA opportunities of possible missions, ranging from sensors for small satellites in the atmosphere, sensors, and skimmers. Another possible option would be a short-lived on the surface of the platform, or some kind of aerial platform is floating in a more temperate climate on Venus, which is located at an altitude of 34 miles (55 km). For longer life of the surface platforms may be, in the medium-term, prior to 2032, the community is represented.

A lot of ideas, and little chance of

But the VEXAG also need to be adapted to the available resources, which is what happens when the us makes the call for the submission of proposals for a cheaper Discovery missions, it is more expensive for New Frontiers missions, and the ride-along, or international opportunities. In the minutes of the community and recommends that to address the projected proposal rate, cadence, and for 2022, with the satellites or to probe the earth’s atmosphere. Between 2023 and 2032, VEXAG, it is recommended to add a surface-cross-platform (long – and short-term) and access equipment is on the wish list.

NASA’s latest Discovery, a call for proposals in 2014, which led to one of the top five finalists, including the two Venus missions, DAVINCI’s, and bureau VERITAS. According to Dyar, nor of Venus, is a mission, it was given for unknown reasons,” even though both were supposed to be selected in the sense that they can be operated immediately. The proposals are lost in the Psyche and Lucy the two missions to study asteroids.

The last of the New Frontiers opportunity is in 2016, and the community is presented to Venus, a mission that is called VOX (Venus for the Origin Explorer), which would focus on a high-resolution, terrain, and height maps of the surface. While the display was supposed to be selecting, NASA did not choose it as a finalist; the winner of that option is the Dragonfly, which is to be flown on the surface of Saturn’s moon, Titan.

NASA’s last dedicated mission to Venus was Magellan, which is a job in October 1990 and was deorbited four years later. The agency will have flown by the planet, as with the Galileo, Cassini, and MESSENGER, on his way to other planets. In the meantime, the European Space Agency has operated the Venus Express to Venus, from 2006 to the end of 2014, and the japanese Akatsuki mission, success is a job in 2015 on the second attempt. Shinobi is the only operational mission to Venus right now.
