Trump Increases NASA Spending by $1.6 Billion With Goal of Returning to Moon

The Trump administration asked Congress on Monday to increase NASA spending next year by an extra $1.6 billion to accommodate the accelerated goal of returning Americans to the surface of the moon by 2024.

The increased funding request, announced by President Donald Trump on Twitter, comes nearly two months after Vice President Mike Pence declared the objective of shortening by four years NASA’s timeline for putting astronauts back on the moon for the first time since 1972.

The proposed increase would bring NASA’s total spending level for the 2020 fiscal year to $22.6 billion. The bulk of the increase is earmarked for research and development for a human lunar landing system, according to a summary provided by NASA.

“Under my Administration, we are restoring @NASA to greatness and we are going back to the Moon, then Mars,” Trump tweeted late on Monday. “I am updating my budget to include an additional $1.6 billion so that we can return to Space in a BIG WAY!” NASA had previously aimed to return crewed spacecraft to the lunar surface by the year 2028, after first putting a “Gateway” station into orbit around the moon by 2024.

The newly accelerated goal – an endeavor likely to cost tens of billions of dollars – comes as NASA has struggled with the help of private partners to resume human space missions from U.S. soil for the first time since the shuttle program ended in 2011.

The U.S. Apollo program, NASA’s forerunner to the effort at returning humans to Earth’s natural satellite, tallied six manned missions to the moon from 1969 to 1972. So far, only two other nations have conducted controlled “soft” landings on the moon – the former Soviet Union and China. But those were with unmanned robot vehicles. (VOA)

Scientists Create Map of Wind Circulation in the Upper Atmosphere of Mars

Scientists map winds in Mars' upper atmosphere for first time

Using data from NASA’s MAVEN spacecraft, researchers have created the first-ever map of wind circulation in the upper atmosphere of Mars.

The new map of Mars winds helps scientists to better understand the workings of the Martian climate, giving them a more accurate picture of its ancient past and its ongoing evolution.

“The observed global circulation provides critical inputs needed to constrain global atmospheric models,” said Mehdi Benna of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“These are the same models that are used to extrapolate the state of the Martian climate into the distant past,” added Benna in the first paper published in the journal Science.

MAVEN (Mars Atmosphere and Volatile EvolutioN mission) celebrated the five-year anniversary of its entrance into orbit around Mars on September 21.

The primary scientific goal of the mission is to study what is left of Mars’ atmosphere to determine how, in the distant past, an ocean-covered and potentially habitable Mars became the dry and desolate place it is today.

“The winds observed in the Martian upper atmosphere are sometimes similar to what we see in global model simulations, but other times can be quite different,” said Kali Roeten of University of Michigan.

“These winds can also be highly variable on the timescale of hours, yet in other cases, are consistent throughout the observation period, said Roeten in the second paper published in the Journal of Geophysical Research-Planets.

Upper atmospheric winds on Earth have already been mapped in detail.

Winds drive a series of processes in the atmosphere that can affect the propagation of radio waves, which are crucial for communications purposes for those on the surface, and the prediction of paths satellites will take in their orbit around Earth.

Mapping Martian winds, therefore, is a crucial step towards understanding characteristics of extraterrestrial atmospheres beyond what we know about processes on Earth.

The upper atmospheric winds on both Earth and Mars are in the planets’ respective thermospheres, which are areas where temperature increases with height.

This discovery was the first detection of topography-induced gravity wave ripples in the thermosphere of any planet, even Earth. (IANS)
