NASA: No contact Made With Storm-Hit Mars Rover, Till Now

Because Opportunity runs on solar energy, scientists had to suspend science activities to preserve the rover's batteries.

 NASA is yet to make contact with its Mars Opportunity Rover ever since a massive storm started on the Red Planet in June.

Based on the longevity of a 2001 global storm, NASA scientists estimate it may be September before the haze has cleared enough for Opportunity to power up and call home, the US space agency said this week.

Scientists first observed a smaller-scale dust storm on May 30. By June 20, it had gone global.

For the Opportunity rover, that meant a sudden drop in visibility from a clear, sunny day to that of an overcast one.

Because Opportunity runs on solar energy, scientists had to suspend science activities to preserve the rover’s batteries.

NASA said no response has been received from the rover as of July 18.

Luckily, all that dust acts as an atmospheric insulator, keeping nighttime temperatures from dropping down to lower than what Opportunity can handle.

But the nearly 15-year-old rover is not out of the woods yet as it could take weeks, or even months, for the dust to start settling.

When the skies begin to clear, Opportunity’s solar panels may be covered by a fine film of dust. That could delay a recovery of the rover as it gathers energy to recharge its batteries. A gust of wind would help, but is not a requirement for a full recovery, NASA said.

While the Opportunity team waits in earnest to hear from the rover, scientists on other Mars missions have gotten a rare chance to study this storm.

The Mars Reconnaissance Orbiter (MRO), Mars Odyssey, and Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiters are all tailoring their observations of the Red Planet to study this global storm and learn more about Mars’ weather patterns.

Meanwhile, the Curiosity rover is studying the dust storm from the Martian surface, the US space agency added. (IANS)

NASA Cancels First All-Female Spacewalk Due to Lack of Small Spacesuit

"An all-woman spacewalk WILL eventually happen"

What should have been a giant leap for womankind has turned into a stumble on the path to equality after U.S. space agency NASA canceled the first all-female spacewalk due to a lack of a spacesuit in the right size.

Anne McClain and Christina Koch had been due to step into history books in a spacewalk Friday, during the final week of Women’s History Month.

But McClain will now give up her place on the mission to her male colleague Nick Hague, NASA announced late Monday.

“Mission managers decided to adjust the assignments, due in part to spacesuit availability on the station,” NASA said in a statement.

“McClain learned during her first spacewalk that a medium-size hard upper torso — essentially the shirt of the spacesuit — fits her best. Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it.”

Nearly 60 years after the first human blasted off into space, less than 11 percent of the 500 plus people who have traveled to space have been women, and spacewalk teams have either been all-male or male-female.

McClain and Koch were both part of the 2013 NASA class that was 50 percent women.

NASA said the decision to change the plan was made in consultation with McClain after a spacewalk last week.

“Anne trained in M and L and thought she could use a large but decided after Friday’s spacewalk a medium fits better,” wrote spokeswoman Stephanie Schierholz on Twitter.

“In this case, it’s easier (and faster!) to change spacewalkers than reconfigure the spacesuit.”

Others said they were sad that a milestone moment on women’s space exploration had been deferred, but safety came first.

“I’m super disappointed about the all-woman spacewalk not happening as scheduled this Friday but I’m also super supportive of astronauts having the authority to say ‘I would be safer using a different piece of equipment’,” wrote Emily Lakdawalla, a senior editor at the U.S. nonprofit The Planetary Society.
