NASA Cosmically speaking, director Bill Nelson has big plans for the agency, including a trip to Venus, advanced view in Soil using 3D Technical And the fall of man Mars.
Speaking in his first “State of NASA” address Wednesday afternoon, the former Florida senator announced the groundbreaking mission, sending Space The community is buzzing.
Big news today besieged Multiple missions to Earth’s “twin” Venus, named VERITAS (Venus Emissions, Radio Science, InSAR, Topography and Spectroscopy) and DAVINCI+ (Deep Atmospheric Exploration for Noble Gases, Chemistry and Imaging).
discovery program The project will map and measure aspects of Venus to understand the planet’s history.
NASA aims for two new missions to Venus to learn more about ‘lost’ world
Meanwhile DAVINCI+ will study the planet’s atmosphere, which may explain whether Venus ever had one oceanVERITAS will focus on the surface in hopes of discovering “why it evolved so differently from Earth.”
MagellanThe last US mission to Venus ended in 1994 after filming starship He was ordered to plunge into the poisonous atmosphere.
Speaking to Fox News on Thursday, Nelson said NASA would return to it to better understand why Venus has such a “very dense, worrying, and unforgiving atmosphere.”
“So what is Venus’ atmosphere created in this way and what secrets are hidden beneath it? And why is it so taboo that even lead will melt on the surface? And this is the secret. Since we have been to Venus in 30 years, we have wanted to reveal the Secret and attempt to understand the origin of Earth and its habitable atmosphere. “
NASA Administrator Bill Nelson speaks to the agency’s workforce during its first State of NASA event on Wednesday, June 2, 2021 at NASA Headquarters in the Mary W. Jackson Building in Washington. Nelson commented on its long history with NASA and, among other topics, discussed the agency’s plans for future Earth-focused missions to tackle climate change and the return of humans and robots to the Moon through the Artemis program, as well as announcing two new planetary sciences. missions to Venus – VERITAS and DAVINCI +.

In his speech, the office also discussed The long awaited Artemis program, where the agency plans to send First person of color and first woman to reach the moon in 2024.
However, critics say that NASA’s target date may be too ambitious, and Government Accountability Office Report Released in May, it said Artemis faced “technical risks as well as management issues”.
In his first interview as an official, Nelson For the Associated Press in May that it is necessary to put a “dose of realism” into the agency’s analysis of Artemis.
With 2024 goals remaining, Nelson warned that “spaces are tough”.

“And we know that when you’re on the cutting edge, developing technology and flying in a very unforgiving environment when safety is your primary concern – we know there are often delays,” he said. “So we also have to be quite realistic about the potential delay.”
Apart from landing humans in monthI will Artemis “Creating continuous exploration in preparation for a mission to Mars.”
“The moon is only 250,000 miles from Earth. To go to Mars, you’re talking about millions of miles. As a result, we can use one-sixth of the Moon’s gravity and learn how to live, how to adapt, how to make fuel from the regolith to the Moon, learn how to capture water there and make fuel, in preparation for how to sustain human life for long-term missions?” Reflected Nelson. “It’s not three or four days of the month and it doesn’t matter how long it takes from there and back and forth. But we’re talking about years to get to Mars and stay there for a few years and come back. And so, we can learn a lot on the moon as we prepare to go to Mars.”
The office also detailed NASA’s recent observations and combat efforts Climate change Using advanced modeling.
in May, NASA He said A new series of Earth-focused missions will be designed to provide critical climate information, Disaster mitigation and improve agricultural operations.
The Earth System Observatory satellite will work with others to “create a three-dimensional view of the Earth,” with a focus on aerosols, clouds, precipitation, mass change, surface biology and geology, and surface deformation and change.
Nelson said that while the agency already has “advanced instruments” in space to make Earth measurements “enhanced” by measurements already made by ocean buoys and planes dropping instrument beams in storms to the ocean floor, five major new science groups are observing ” enlargement”. ” Effort.
“The first on January 23 which will measure earthquakes and lava flows and buildup and add coasts and mountainous terrain. And you can add the rest that are over a decade old and you’ll create these 3D dimensions to understand how all the elements we see relate to each other. some.” “Earth, Water, Atmosphere and Ice”.
“When we have this global outlook, we can report much better on what we are doing on the pitch to become better agents. How can we be more efficient – like agricultural crops – and how can we sustain things, not only like farming, but how can we predict things that might happen in the future, like droughts, insects, or storms — anything that could we disturb as inhabitants of the earth,” he said. “And that’s what we’re going to do over the next decade.”
In the latest issue describing the Earth System ObservatoryNASA says one of the first initiatives involved a partnership with the Indian Space Research Organization (ISRO) to measure changes in the Earth’s surface by less than half an inch using two different radar systems.
