After spending more than a year on a twisting ridge on Mars, NASA’s Curiosity rover has snapped its last selfie as it moves on to new sights on the Red Planet.
“Curiosity rover has taken its last selfie on the Vera Rubin Ridge and descended toward a clay region of Mount Sharp. The twisting ridge on Mars has been the rover’s home for more than a year, providing scientists with new samples and new questions to puzzle over,” NASA said in a statement on Monday.
On January 15, Curiosity used its Mars Hand Lens Imager (MAHLI) camera on the end of its robotic arm to take a series of 57 pictures, which were stitched together into the selfie.
The images feature a location on the ridge called Rock Hall, which the rover drilled on December 15.
The Rock Hall drill hole is visible to the lower left of the rover; the scene is dustier than usual at this time of the year due to a regional dust storm.
Curiosity has been exploring the ridge since September 2017.
It is now heading into the “clay-bearing unit”, which sits in a trough just south of the ridge.
Clay minerals in this unit may hold more clues about the ancient lakes that helped form the lower levels on Mount Sharp, NASA said.
Curiosity, which landed on Mars in 2012, was designed to assess whether Mars ever had an environment able to support small life forms called microbes. In other words, its mission is to determine the planet’s “habitability”. (IANS)
After NASA and SpaceX successfully completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket, Elon Musk said that his aerospace company aims to send NASA astronauts to space between April and June this year.
This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station (ISS) under NASA’s Commercial Crew Programme, the US space agency said in a statement on Sunday.
With this test now complete, the next big flight of the Crew Dragon will have people on board: NASA astronauts Bob Behnken and Doug Hurley.
“We’re highly confident that the hardware will be ready in Q1, most likely at the end of February but no later than March. And we think it appears probable that the first crewed launch would occur in the second quarter,” said Musk after the successful uncrewed test of its Crew Dragon capsule’s in-flight launch escape capabilities.
Musk said that if all goes well, the first crewed flight on the Crew Dragon could take place in the second quarter of this year.
“This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil,” said NASA Administrator Jim Bridenstine. “We are thrilled with the progress NASA’s Commercial Crew Programme is making and look forward to the next milestone for Crew Dragon.”
As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 am just off the Florida coast in the Atlantic Ocean.
“As far as we can tell thus far, it’s a picture perfect mission. It went as well as one can possibly expect,” said Musk. “This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I’m super fired up. This is great.”
Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX’s Demo-2 mission. “The past few days have been an incredible experience for us,” said astronaut Doug Hurley.
“Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can’t wait to take a ride to the space station soon,” he said in the NASA statement. (IANS)
