NASA’s Parker Solar Probe, which is humanity’s first mission to the Sun, has cleared the final procedures ahead of its launch on August 11.

“NASA’s Parker Solar Probe has cleared the final procedures in the clean room before its move to the launch pad, where it will be integrated onto its launch vehicle, a United Launch Alliance Delta IV Heavy,” the space agency said in a statement.

The mission termed as historic “will revolutionize our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds”, it added.

The Parker Solar Probe will travel through the Sun’s atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions and ultimately providing humanity with the closest-ever observations of a star.

In addition to using the largest operational launch vehicle, the Delta IV Heavy, the Parker Solar Probe will use a third stage rocket to gain the speed needed to reach the Sun, which takes 55 times more energy than reaching Mars.

The spacecraft will travel directly into the Sun’s atmosphere, about 4 million miles from its surface and more than seven times closer than any spacecraft has come before, due to its innovative Thermal Protection System.

The mission will perform the closest-ever observations of a star when it travels through the Sun’s outer atmosphere, called the corona.

The mission will rely on measurements and imaging to revolutionize our understanding of the corona and how processes there ultimately affect near-Earth space, NASA said. (IANS)

Chandra Observatory By NASA Back in Action

Scientists are currently performing analyses and tests to determine what options were available to recover the gyro to operational performance

NASA Chandra X-Ray Observatory, observing the universe in high-energy light since 1999, is back in action after suffering a glitch due to the failure of the gyroscope and going into safe mode last week.

The cause of Chandra’s safe mode on October 10 has now been understood and the Operations team has successfully returned the spacecraft to its normal pointing mode, according to the US space agency.

“The safe mode was caused by a glitch in one of Chandra’s gyroscopes resulting in a 3-second period of bad data that, in turn, led the on-board computer to calculate an incorrect value for the spacecraft momentum. The erroneous momentum indication then triggered the safe mode,” NASA said in a statement late on Monday.

The team has completed plans to switch gyroscopes and place the gyroscope that experienced the glitch in reserve.

Once configured with a series of pre-tested flight software patches, the team will return Chandra to science operations which are expected to commence by the end of this week, NASA said.

On October 10, Chandra X-ray Observatory entered safe mode, in which the observatory is put into a safe configuration, critical hardware is swapped to back-up units, the spacecraft points so that the solar panels get maximum sunlight, and the mirrors point away from the Sun.

Chandra is 19 years old, which is well beyond the original design lifetime of five years. In 2001, NASA extended its lifetime to 10 years.

The US space agency said that it was also continuing to work towards resuming science operations of the Hubble Space Telescope that on October 5, entered safe mode after one of the three gyroscopes (gyros) being used to point and steady the telescope failed.

Gyroscopes help spacecraft maintain proper orientation.

Scientists are currently performing analyses and tests to determine what options were available to recover the gyro to operational performance.

Till that time, science operations with Hubble have been suspended.

Besides Chandra and Hubble, NASA’s planet-hunting Kepler space telescope is also almost out of fuel. Kepler has found about 70 per cent of all known alien worlds to date.

The space agency’s Mars rovers Opportunity and Curiosity too have faced issues of late. (IANS)
