Washington, Oct 2 : US space agency NASA has completed 60 years of human space exploration, discovering the world beyond Earth and developing new technologies.
"For six decades, NASA has led peaceful exploration of space, making discoveries about our planet, our solar system, and our universe," the agency posted on its website late on Monday.
NASA has not just launched spacecrafts to unlock mysteries of the universe, dispatched probes to make close-up observations of every planet in the solar system, but has also, in August, sent a probe named Parker Solar Probe to the Sun.
The historic small car-sized probe will journey steadily closer to the Sun until it makes its closest approach at 3.8 million miles.
The agency has also conducted nine manned missions and is planning for a human return to the Moon, followed by missions to Mars and beyond.
The National Aeronautics and Space Administration (NASA) officially opened for business for the first time on October 1, 1958.
It was created by then President Dwight D. Eisenhower to lead America's civilian space programme in response to the then USSR's advances in space exploration.
In just 10 days after opening its doors, NASA launched its first spacecraft -- Pioneer 1. Although it did not achieve its intended mission to orbit the Moon due to a rocket malfunction, Pioneer 1 did reach a record altitude of about 70,000 miles, highest till then.
The probe returned scientific data confirming the existence of the Van Allen radiation belts until it burned up on re-entry into the Earth's atmosphere 43 hours after launch, the post said.
In the US, NASA's research made great advances in aviation, helped to develop a commercial space industry, enriched the economy, created jobs, and strengthened national security.
The agency also remembered the sacrifices laid down by astronauts during space research. "The tragic loss of lives including aviation pilots and the crewmembers of Apollo 1, Challenger, and Columbia (which included Indian-born astronaut Kalpana Chawla)...," the post said.
Chawla was one of the seven crew members who died in the Space Shuttle Columbia disaster when the craft disintegrated during its re-entry into the Earth's atmosphere on February 1, 2003.
"Sacrifice has also come in the countless hours dedicated by the NASA personnel -- on the ground and in space -- (that they) have spent away from families to plan and execute missions."
"We will go back to the Moon to learn more about what it will take to support human exploration to Mars and beyond... We will continue to try to answer the question: "Are we alone?" NASA said.

Jaipur, Mar 28: Young Riyan Parag showed why he is considered a precocious talent as he struck a stunning 84 not out off 45 balls to set up a 12-run win for Rajasthan Royals against Delhi Capitals in their IPL match here on Thursday.
Sent in to bat, RR were reduced to 36 for 3 in the eighth over but the 22-year-old Parag single-handedly took the home side to 185 for 5 with a magnificent unbeaten knock studded with seven fours and six sixes.
Parag, who was promoted to number 4 by the team management this season and made 43 in the previous match, took 25 runs off veteran South African pacer Anrich Nortje with scores of 4, 4, 6, 4, 6, 1 in the final over to hit his highest T20 score.
Chasing 186 for a win, DC could only manage 173 for 5 in 20 overs though South African youngster Tristan Stubbs (44 not out off 23 balls) kept them in the hunt till the final over from which they needed 17 runs.
Avesh Khan conceded just four runs to help RR win their second consecutive match.
South African pacer Nandre Burger and Yuzvendra Chahal took two wickets apiece to also contribute in the RR win.
"Definitely disappointed. The best thing to do from here is to learn from it. The bowlers did well through the 15-16 overs. But the batters did well at the death, hopefully we do better in the next game," DC skipper Rishabh Pant said.
DC were reduced to 34 for 2 in the fourth over with Burger taking two wickets in three balls in a fine display of fast bowling.
Burger, who was brought in as Impact Sub for Shimron Hetmyer, dismissed opener Mitchell Marsh (23 off 12 balls) and Ricky Bhui (0) in the fourth over.
DC captain Rishabh Pant came out to bat at the fall of Bhui's wicket and along with senior batter David Warner built the innings without taking too much risk. Delhi were 89 for 2 at the halfway stage.
Warner was the more aggressive one as he got the boundaries to keep DC in the hunt. The senior Australian batter fell one run short of his fifty courtesy a brilliant diving catch by Sandeep Sharma off the bowling of Avesh in the 12th over.
Warner and Pant were involved in a crucial 67-run partnership for the third wicket.
Playing in his 100th IPL match and 14 months after a horrible car crash, Pant tried to build the innings with occasional boundaries. But he got out for a 26-ball 28 as Chahal induced a faint lower edge for Sanju Samson to do the rest behind the stumps in the 14th over.
The asking rate shot up to more than 13 runs an over and DC needed 66 from the last five overs.
Stubbs kept DC in the game with two consecutive sixes off Ravichandran Ashwin in the 17th over, but in the end the Delhi side were short by 12 runs.
They needed 34 runs from the final two overs which they could not get. It was DC's second consecutive loss.
Earlier, Parag shared 54 and 52 runs respectively with Ravichandran Ashwin (29) and Dhruv Jurel (20) after RR made a shaky start.
Royals captain Samson struck three consecutive boundaries in the fourth over bowled by pacer Mukesh Kumar before nicking a Khaleel Ahmed delivery two overs later to Pant to get out for 15.
RR were 30 for 2 by then as Mukesh had given DC their first breakthrough with the wicket of Yashasvi Jaiswal (5).
The Royals were in more trouble after wrist spinner Kuldeep Yadav literally forced his captain Pant to take a review, which later proved to be successful, to dismiss Englishman Jos Buttler for an LBW decision.
Ashwin came out to bat at number five and he lofted a Kuldeep delivery for a six to help RR reach 58 for 3 at halfway stage. He gave Nortje even a harsher treatment with two sixes in the next over that yielded 15 runs.
Ashwin, however, holed out to Tristan Stubbs near the boundary ropes for a 19-ball 29.
Parag then made his presence felt, striking two boundaries and a six off Ahmed to take RR past 100 in the 15th over.
