NASA aims to launch Mars rover twin in 2020
The new rover will use spare parts and engineering models developed for Curiosity, which is four months into a planned $2.5 billion mission on Mars to look for habitats that could have supported microbial life.
Replicating the rover’s chassis, sky-crane landing system and other gear will enable NASA to cut the cost of the new mission to about $1.5 billion including launch costs, John Grunsfeld, the US space agency’s associate administrator for science, said at the American Geophysical Union conference in San Francisco.
Budget shortfalls forced NASA to pull out of a series of joint missions with Europe, designed to return rock and soil samples from Mars in the 2020s. Europe instead will partner with Russia for the launch vehicle and other equipment that was to have been provided by NASA.
Grunsfeld said NASA will provide a key organics experiment for Europe’s ExoMars rover, as well as engineering and mission support under the agency’s proposed budget for the year beginning Oct. 1, 2013. T he United States also will provide the radio communications equipment for a planned European orbiter slated to launch in 2016.
Details about what science instruments would be included on the new rover, whether or not it would have a cache for samples, and the landing site have not yet been determined.
NASA plans to set up a team of scientists to refine plans for the rover and issue a solicitation next summer.
The National Academy of Sciences last year ranked a Mars sample return mission as its top priority in planetary science for the next decade.
“The (science) community already has come forward with a very clear message about what the content of the next Mars surface mission should be, and that is to cache the samples that will come back to Earth,” said Steve Squyres with Cornell University.
“That’s really a necessary part of having this mission,” he said.
HUMANS MISSIONS TO MARS
NASA had considered flying an orbiter in 2018, but decided instead to provide equipment for the European probes, extend its ongoing Mars missions and develop the Curiosity twin rover for launch in 2020. “We could have come up with something in 2018, but with the budget that we’re in we would not have had such a full program. It would have been a down-scaled orbiter of some kind,” Grunsfeld said.
Under the revamped Mars plan, Curiosity’s two-year mission would be extended to five years.
The new rover also would help NASA prepare for eventual human missions to Mars, a long-term objective of the US space program.
“If we think of the 2030s as the potential for human exploration, I think this 2020 rover and the other things we might be able to do in the 2020s as a synergistic collaboration between science and human spaceflight. There are a lot of cool things we can do,” Grunsfeld said.
‘Solo: A Star Wars Story’ struggles to take off in opening weekend
LOS ANGELES: “Solo: A Star Wars Story,” the latest prequel in the hugely popular film franchise, struggled to achieve escape velocity this holiday weekend, with an estimated $101 million four-day take falling far below expectations.
Analysts had predicted the Disney/Lucasfilm project — directed by Ron Howard and with Alden Ehrenreich as a young version of the swashbuckling Han Solo — would reach $130 million to $150 million, possibly setting a Memorial Day weekend record.
But the film, with a cast including Donald Glover, Woody Harrelson and Emilia Clarke, was falling short not only in North America, box office tracker Exhibitor Relations predicted, but also abroad.
“The news is grim overseas,” said Hollywood Reporter, saying the film was heading for barely half the $300 million global take many had predicted.
Last weekend’s No. 1 film, “Deadpool 2” from 20th Century Fox and Marvel, took second spot this weekend, with a four-day estimate of $53.5 million.
That movie stars Ryan Reynolds as the foul-mouthed, irreverent title character as he forms an X-Force team to protect a young mutant from evil Cable (Josh Brolin).
Third place went to Disney/Marvel collaboration “Avengers: Infinity War,” which took in $20.1 million in its fifth weekend out. It stars Robert Downey Jr., Benedict Cumberbatch, Scarlett Johansson and Chris Hemsworth.
In fourth, with $12 million in ticket sales, was a movie featuring no superheroes or interplanetary battles, and with a sedate sounding title — “Book Club” — that belies its racy story line.
The Paramount film tells the story of four aging friends — Jane Fonda, Diane Keaton, Candice Bergen and Mary Steenburgen — who decide to read the steamy book “Fifty Shades of Grey” and find it stimulating more than just their intellects.
And in fifth was Warner Bros. comedy “Life of the Party,” at $6.5 million. It stars Melissa McCarthy as a newly divorced mother who returns to college, only to find herself in class with her (deeply embarrassed) daughter.
