Washington, Oct 31: A NASA sounding rocket launched with the aim of studying the darks voids in between the stars and galaxies that fill the night sky has failed to deliver science data because of a possible issue with the attitude control system.

The Dual-channel Extreme Ultraviolet Continuum Experiment, or DEUCE for short, was launched on Monday from the White Sands Missile Range in New Mexico.

“The Black Brant IX sounding rocket performed nominally. However, science data was not obtained because of a possible issue with the attitude control system,” NASA said in a statement late on Monday.

“The payload descended by parachute and was recovered. The Sounding Rocket Program Office is investigating the anomaly,” it added.

The cold, diffuse gas between galaxies — called the intergalactic medium, or IGM for short — hardly emits any light.

To shed light on the nature of the IGM, the sounding rocket was equipped with special ultraviolet optics.

The experiment was designed to measure starlight from a pair of nearby hot stars in the constellation Canis Major, aiming to help researchers understand how the IGM got to its current state.

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)
