Washington, Jan 5, 2017: Aiming to find important clues to the earliest history of the solar system, NASA has announced two missions — one to explore Jupiter’s mysterious Trojan asteroids and the other to study a unique metal asteroid.

The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively, NASA said in a statement on Wednesday.

“Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids, while Psyche will study a unique metal asteroid that’s never been visited before,” said Thomas Zurbuchen, Associate Administrator for NASA’s Science Mission Directorate in Washington.

“This is what Discovery Program missions are all about – boldly going to places we’ve never been to enable groundbreaking science,” Zurbuchen added.

Lucy, a robotic spacecraft, is scheduled for October 2021 launch. It is slated to arrive at its first destination, a main belt asteroid, in 2025.

From 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids.
These asteroids are trapped by Jupiter’s gravity in two swarms that share the planet’s orbit, one leading and one trailing Jupiter in its 12-year circuit around the sun.

The Trojans are thought to be relics of a much earlier era in the history of the solar system, and may have formed far beyond Jupiter’s current orbit.

“This is a unique opportunity,” said Harold Levison, Principal Investigator of the Lucy mission from the Southwest Research Institute in Boulder, Colorado.

“Because the Trojans are remnants of the primordial material that formed the outer planets, they hold vital clues to deciphering the history of the solar system. Lucy, like the human fossil for which it is named, will revolutionize the understanding of our origins,” Levison noted.

The Psyche mission will explore one of the most intriguing targets in the main asteroid belt – a giant metal asteroid, known as 16 Psyche, about three times farther away from the sun than is the Earth.

This asteroid measures about 130 miles (210 kilometers) in diameter and, unlike most other asteroids that are rocky or icy bodies, is thought to be comprised mostly of metallic iron and nickel, similar to Earth’s core.

The mission will help scientists understand how planets and other bodies separated into their layers – including cores, mantles and crusts – early in their histories.

Psyche, also a robotic mission, is targeted to launch in October of 2023, arriving at the asteroid in 2030, following an Earth gravity assist spacecraft maneuvre in 2024 and a Mars flyby in 2025. (IANS)

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

"I am updating my budget to include an additional $1.6 billion so that we can return to Space in a BIG WAY!"

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)
