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)

Rocket Lab is Set To Launch 10 NASA CubeSats

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space

In its first mission for NASA, the American aerospace manufacturer Rocket Lab is set to launch 10 small research satellites, or CubeSats, from New Zealand, the US space agency said.

Owing to bad weather, Rocket Lab was forced to postpone the earlier decided launch on December 12.

Rocket Lab is now targeting the ELaNa-19 launch on December 15 with a launch window opening at 11 p.m. EST from the company’s launch complex on the Mahia Peninsula in New Zealand, NASA said in a statement on Friday.

The CubeSats were built by three NASA centres, seven universities, and a middle school under the NASA’s Educational Launch of Nanosatellites, or (ELaNa-19) mission.

ElaNa-19 is NASA’s first to be completely dedicated to launching CubeSats under the agency’s Venture Class Launch Services program for small-satellite launches.

More than 250 students have been involved in the design, development and construction of the CubeSats scheduled to be flown as payloads on Rocket Lab’s Electron rocket.

“The major difference between today’s launch and previous #ELaNa missions is that for the first time, NASA will have a launch completely dedicated to CubeSats rather than having the small satellites ride along with a much larger spacecraft that is the primary mission,” NASA Launch Services Program officials wrote on Twitter on December 12.

The 10 CubeSats are named as CubeSail, CeREs, NMTSat, CHOMPTT, ALBus, STF-1, ISX, RSat, Shields-1 and DaVinci, NASA said.

These are built to standard dimensions of one unit (1U), and can be 1U, 2U, 3U or 6U in size. They generally weigh less than 1.33 kg per U — 6U may be up to 12 kg.

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space.

After the main payload deploys, the CubeSats will separate from their RailPODs. After 45 minutes in orbit, the CubeSat transmitters will turn on and university ground stations will listen for their beacons, determine their small satellites’ functionality and announce operational status.

CubeSat mission durations and orbital life vary but are anticipated to last at least three years. Upon mission completion, the CubeSats fall to Earth, burning up in the atmosphere, NASA noted. (IANS)
