June 21, 2017: The smallest satellite in the world, called “KalamSat’, was launched by NASA. The 64 gms weighing satellite was designed and built by Rifath Sharook, an 18-year-old Indian boy.

Sharook, hailing from Pallapati in Tamil Nadu, and his team of six rejoiced as the record was set on Wednesday. His experiment was selected by NASA after he demonstrated his invention in a competition called ‘Cubes in Space’. An organization called ‘Space Kidz India’ funded the satellite. Rafith has been a member of the organization since class 8th.

To create the satellite, Rafith and team used carbon fiber polymer. KalamSat was able to operate for 12 minutes in microgravity. According to the inventor, the purpose of the satellite is to “demonstrate the performance of 3-D printed carbon fiber.”

Rafith was generous enough to dedicate his record-setting invention after APJ Abdul Kalam, former President, and a remarkable nuclear scientist.

Sharook is a genius scientist. In 2015, he reportedly launched a 1200g helium weather balloon from a ground in Kelmabakkam.

The 64 gram glory has made another record as this is the first time NASA has carried out an experiment by Indian students. Unfortunately, the group could not attend the launch which took place in Wallop’s islands.

Rifath aims to start a private space organization in India.

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.
